Abstract:
Context. Nest boxes are a useful tool in the reintroduction, conservation and monitoring of many hollow-using species. Aims. All forms of nest-box monitoring involve some form of invasion, often upsetting their continued use by occupants. We conducted a pilot study to investigate and validate the innovative use of temperature dataloggers (iButtons®) to remotely monitor nest-box use, leaving the nest-box occupants untouched. Methods. In captivity, iButton recordings revealed the duration and time of day when each of the three nest-box designs was occupied by Pseudocheirus occidentalis (western ringtail possums); the accuracy of occupancy data was validated by unobtrusive infrared video recording. In the field, where translocated P. occidentalis and naturally occurring Trichosurus vulpecula (common brushtail possum) populations are present, hair sampling at the nest-box entrances (in addition to iButton recording) was used to identify the mammal species present. Key results. Nest-box use by captive P. occidentalis validated iButtons as a useful remote-monitoring tool, with <5–6% error for two nest-box designs. Although there was limited use of nest boxes at the field site, our results confirmed that iButtons are useful for remote-monitoring of nest-box use in the field; iButton data revealed both short (<2 h) and long (>10 h) periods of continuous occupancy (T. vulpecula only). In addition to the convenience (to researcher and animal) of continuous (24-h) monitoring with minimal disturbance, a major advantage from using iButtons is that occupancy can be matched with environmental temperature or rainfall records, as well as other events (e.g. storms or frost). Conclusions. iButtons are a useful remote-monitoring tool of nest boxes, and it is possible that their use in this manner may be extended to tree-hollow occupation. Most importantly, this approach can inform us as to the conditions under which the nest boxes are used by fauna, as well as preferences for different nest-box designs. Implications. It is important to note that the criteria used for determining the presence or absence in the nest box (i.e. temperature difference, Tin– Tout, of 2°C) in the present study will not be relevant for all nest-box designs and before using these methods, the thermal properties of the nest box or tree hollow will require investigation.

Abstract:
Swiftlet nest farming is one of the businesses found in Indonesia due to its bigeconomic value. Nest quality at the time when harvest is able to impact the selling price ofswiftlet nest. Farmers usually monitor the swiftlet nest by checking the nest directly in thebuilding, this matters because the swiftlet is shocked. Monitoring is needed for checking thephysical condition of the swiftlet nest. This research will make a prototype hopefully useful toswiftlet nest farmers as a reference to increase nest quality with high economic value. Theresearch has been done on software and hardware design by ESP32-CAM and Arduino IDEsoftware for making the source code. The result from research of a monitoring system onswiftlet nest farming based ESP32-CAM equipped with telegram is able to send commandsmenu to telegram, capturing photo of swiftlet nest, turning on flash and turning off flash onESP32-CAM. The research has been realized successfully as design.

Abstract:
In the breeding seasons of 2013–2023, monitoring of the permanent breeding territory of a pair of Short-Toed Eagles (Circaetus gallicus) was conducted in the southern shore of Lake Balkhash, in the transition landscape of wetland to desert biome, in a wooded area dominated by Turanga Poplar (Populus diversifolia). It was found that, at least during the 2017, 2021, and 2022 breeding seasons, nearly fully feathered nestlings were eaten by an Asiatic Wildcat (Felis lybica ornata) shortly before they fledged from their nests. All nests observed during the monitoring periods were located in the uppermost center of a poplar tree crown. Starting in 2021, a DJI Mavic 2 PRO quadrocopter was used for monitoring. Using a Bushnell Nature View 12MP camera trap in 2017, an Asiatic wildcat was found to have repeatedly visited the nest at the top of a tall poplar tree during the breeding season, but did not eat neither the egg nor the nestling at various stages of its development. A pair of Short-Toed Eagles from this nest was tolerant of a pair of Shikras, or little banded Goshawkes (Accipiter badius), nesting 5 m away in a neighboring poplar. Adult Shikras, on the contrary, showed aggressive behavior toward Short-Toed Eagles approaching their nest, especially after their nestlings had hatched. Notably, in 2022 and 2023 the Short-Toed Eagles reused the same nest. Moreover, despite a negative breeding outcome in 2022, the pair successfully raised a nestling in 2023 until it fledged from the nest. The nestling, sometimes accompanied by one of the parents, was still in this poplar grove in late August and early September of 2023, often resting in a large poplar 70 m from the nest. The nest itself also continued to be used as a roost and foraging area, where prey, mainly Long-Eared Hedgehogs (Hemiechinus auritus), were brought and eaten.

Abstract:
The People's Trust for Endangered Species (PTES) owns a private woodland on the Isle of Wight (IoW) that is managed predominantly for woodland bats, Red Squirrels and Hazel Dormice. Dormice are considered to be widespread across the island in suitable habitat. The IoW is different from the mainland as it has no wild deer species. PTES has been monitoring dormice in its woodland since 1992, when nest boxes were first put up by Paul Bright. However, in spite of appropriate woodland management for dormice at the reserve, dormouse numbers there appear to be declining. This raised the question: "Is the apparent decline in dormice recorded in nest boxes, real or perceived?" If the decline was real, it may be necessary to reconsider management advice that we give for dormice. If the decline was perceived, then it may be necessary to reconsider advice that we give for monitoring dormice. The first challenge was to identify what the woodland may have looked like 30 years ago and identify why high numbers of dormice were recorded. We could then apply the known woodland management that was done in the intervening years, to determine why dormouse nest box occupancy changed by varying amounts in different parts of the wood. We were able to check some of our ideas using data from footprint tunnels and this work is ongoing in 2022. This talk will discuss woodland state, woodland management and dormouse next box occupancy in a dormouse hotspot in southern England.

Abstract:
Population size assessments for nocturnal burrow-nesting seabirds are logistically challenging because these species are active in colonies only during darkness and often nest on remote islands where manual inspections of breeding burrows are not feasible. Many seabird species are highly vocal, and recent technological innovations now make it possible to record and quantify vocal activity in seabird colonies. Here we test the hypothesis that remotely recorded vocal activity in Cory’s shearwater (<i>Calonectris borealis</i>) breeding colonies in the North Atlantic increases with nest density, and combined this relationship with cliff habitat mapping to estimate the population size of Cory’s shearwaters on the island of Corvo (Azores). We deployed acoustic recording devices in 9 Cory’s shearwater colonies of known size to establish a relationship between vocal activity and local nest density (slope = 1.07, <i>R2</i> = 0.86, <i>p</i> &lt; 0.001). We used this relationship to predict the nest density in various cliff habitat types and produced a habitat map of breeding cliffs to extrapolate nest density around the island of Corvo. The mean predicted nest density on Corvo ranged from 6.6 (2.1–16.2) to 27.8 (19.5–36.4) nests/ha. Extrapolation of habitat-specific nest densities across the cliff area of Corvo resulted in an estimate of 6326 Cory’s shearwater nests (95% confidence interval: 3735–10,524). This population size estimate is similar to previous assessments, but is too imprecise to detect moderate changes in population size over time. While estimating absolute population size from acoustic recordings may not be sufficiently precise, the strong positive relationship that we found between local nest density and recorded calling rate indicates that passive acoustic monitoring may be useful to document relative changes in seabird populations over time.

Abstract:
In late 2020, a private volunteer group operating through a Facebook group approached Toronto and Region Conservation Authority (TRCA) with an interest in participating in the Citizen Science Nest Protection and Monitoring Volunteer Program. During the 2021 season, TRCA staff virtually trained volunteers in turtle nest detection, protection, and monitoring due to COVID-19 social constraints, and provided necessary supplies and equipment. In 2021 volunteers and staff detected 181 turtle nests and were able to protect 75 nests with simple predator-exclusion devices, while in 2022, 165 nests were detected, and 155 were protected. The volunteers also collected data, including nesting location, date, and species in addition to the number of successful hatchlings (2021 only). In 2021, the 75 protected nests yielded 81 Midland Painted Turtle and 665 Snapping Turtle hatchlings. Five Midland Painted Turtle’s eggs were also recovered from an injured turtle, and 44 Snapping Turtle eggs were recovered from a partially predated nest, transported to the Ontario Turtle Conservation Centre, incubated, hatched, and overwintered, and then released back into the local wetlands. The partnership with a local community group proved effective, and we would recommend this practice to other conservation organizations interested in turtle nest protection.

Abstract:
Abstract Accurate assessment of great ape populations is a prerequisite for conservation planning. Indirect survey methods using nest and dung, and a set of conversion parameters related to nest decay rates, are increasingly used. Most surveys use the standing crop nest count (SCNC) method, whereby nests are counted along transects and the estimated nest density is converted into chimpanzee density using an often non-local nest decay rate. The use of non-local decay rate is thought to introduce substantial bias to ape population estimates given that nest decay rates vary with location, season, rainfall, nest shape, and tree species used. SCNC method has previously been applied in Mbam-Djerem National Park (MDNP) in Cameroon, for chimpanzee surveys using a non-local nest decay rate. This current study aimed to measure a local nest decay rate for MDNP and implications for chimpanzee population estimates in the MDNP. The mean nest decay rate estimated using a logistic regression analysis was 127 [95% CI (100–160)] days. Moreover, the results suggested that rainfall strongly influenced the nest decay rate over the early stage of the lifetime of the nests. The study confirms that estimates of chimpanzee density and abundance using non-local decay rates should be treated with caution. Our research emphasized the importance of using local nest decay rates and other survey methods which do not depend on decay rates to obtain more accurate estimates of chimpanzee densities in order to inform conservation strategies of these great apes in MDNP.

Abstract:
Artificial shelters show great promise as novel, non-invasive tools for studying hellbenders, but their use thus far has faced several challenges. During initial trials in multiple river networks, artificial shelters routinely became blocked by sediment and dislodged during high stream discharge events, and were rarely used by hellbenders. We sought to determine whether these complications could be overcome via alternative shelter design, placement, and maintenance. Between 2013 and 2018, we deployed 438 artificial shelters of two different designs across ten stream reaches and three rivers in the upper Tennessee River Basin. We assessed evidence for several hypotheses, postulating broadly that the availability, stability, and use of artificial shelters by hellbenders would depend on how shelters were constructed, deployed, and/or maintained. We found that maintaining shelters at least once every 40 days limited sediment blockage, and building ~ 40 kg shelters with 3-4 cm thick walls and recessed lids improved their stability during high discharge events. Additionally, we found that hellbenders most frequently occupied and nested in artificial shelters when they were deployed in deeper (~50+ cm) portions of reaches with high adult hellbender densities. Our results suggest that artificial shelters can serve as effective tools for studying hellbenders when designed, deployed, and maintained with these advancements, but also highlight some limitations of their use.<br>Master of Science<br>Hellbenders are large, fully-aquatic salamanders that live primarily in cool, rocky, swift-flowing streams in portions of Appalachia and the lower Midwest. They are imperiled across most of their native range due to human-caused habitat degradation, but their declines, conservation needs, and population status have historically been difficult to study due to the fact that they spend the majority of their lives beneath large, often inaccessible boulders. While these boulders are sometimes possible to lift, doing so can disturb critical hellbender habitat. Therefore, alternate, less invasive hellbender sampling methods are necessary in order to improve knowledge about their conservation status and needs. Artificial shelters, which are large, hollow, concrete structures that mimic natural boulder crevices and feature removable lids, show promise as a novel, innovative tool for non-invasively studying hellbenders. However, initial trials of these shelters have yielded mixed results, with shelters often becoming swept away and destroyed during floods, becoming blocked by sand and sediment and thus inaccessible to hellbenders, or simply not being used by hellbenders when accessible. We sought to determine whether these complications could be overcome by optimizing the way that shelters were constructed, deployed, and maintained in streams inhabited by hellbenders. Between 2013 and 2018, we deployed 438 artificial shelters of two different designs across ten stream reaches and three rivers in the upper Tennessee River Basin. Using multiple analyses, we tested one broad overall hypothesis: that the efficacy of using artificial shelters to study hellbenders would depend on how they were constructed, how frequently they were maintained, and where they were placed in the stream. We found that maintaining shelters at least once every 40 days limited sediment blockage, and building ~ 40 kg shelters with 3-4 cm thick walls and recessed lids improved their stability during flood events. Additionally, we found that hellbenders most frequently occupied and nested in artificial shelters when they were deployed in deeper (~50+ cm) portions of reaches with high adult hellbender densities. Our results suggest that artificial shelters are effective tools for studying hellbenders when designed optimally, maintained frequently enough, and placed in appropriate locations. However, exceptions to these findings may exist in certain heavily degraded stream reaches.

Abstract:
Uma das abelhas solitárias sugeridas para programas de polinização controlada foi Centris analis, pela constância e abundância no Brasil. Estudos mostraram a importância de C. analis na polinização de algumas culturas agrícolas, e vários trabalhos trazem informações a respeito da sua biologia. No entanto, ainda faltam informações a respeito de fatores capazes de aumentar ou diminuir a população de C. analis. Assim ninhos-armadilha confeccionados com cartolina foram oferecidos no campus da Universidade de São Paulo Ribeirão Preto, com dimensões de 0,6cm de diâmetro e em quatro comprimentos diferentes (6, 7, 8 e 9cm), de outubro de 2010 a setembro de 2012. Resultando em 500 ninhos de onde emergiram 369 fêmeas e 562 machos de C. analis, a mortalidade ocorreu em decorrência dos parasitas Leucospis sp. (100), Coelioxys sp. (55), Anthrax sp (3), por causa de fungos (107) e por causas desconhecidas (100). Ninhos-armadilha de 6 e 7cm apresentaram até quatro células, já os ninhos de 8 e 9cm apresentaram até seis células, sendo os ninhos de 8cm os mais utilizados. A razão sexual apresentou-se desviada para machos e os resultados indicam que o comprimento dos ninhos-armadilha não foi capaz de influenciar a razão sexual dessa abelha. Fêmeas de C. analis que nidificaram entre outubro de 2010 a abril de 2012 foram monitoradas (n=28) quanto ao seu comportamento na área; a atividade delas variou de 6 a 24 dias. Cinco fêmeas apresentaram comportamento considerado diferente do padrão e foram coletadas para dissecção, apresentando uma larva parasitoide em seu abdômen. Três delas fizeram depósitos adicionais de óleo em ninhos terminados dias antes, e normalmente não recebem mais materiais; as outras duas fêmeas foram coletadas após fazerem um falso fechamento, quando fecham a entrada do ninho-armadilha sem construir células de cria nele. As cinco fêmeas construíram ninhos convencionais nos primeiros dias de monitoramento, mas cessaram a construção de ninhos com células de cria e passaram a realizar os comportamentos atípicos. Esses comportamentos sugerem que as fêmeas tornam-se estéreis conforme a larva parasitoide cresce, primeiramente pela perda do espaço para transportar néctar para o ninho, e depois pela perda dos órgãos internos. Antes de morrer várias C. analis, machos e fêmeas, ocultaram-se dentro dos ninhos-armadilha, possivelmente por influência do parasitoide. C. analis encontradas mortas tem sido recolhidas de janeiro de 2008 a setembro de 2012, totalizando 186 abelhas mortas, de onde emergiram 113 conopideos adultos, pertencentes a oito espécies. A maioria foi encontrada nos três primeiros meses do ano, período de maior atividade dos hospedeiros. Assim, conclui-se que somente o comprimento dos ninhos-armadilhas utilizados não é capaz de influenciar a razão sexual da prole; as mortes nos ninhos ocorre principalmente pelos ataques de Leucospis sp., por fungos ou por causas desconhecidas, e um importante inimigo natural dos adultos são os conopideos.<br>One of the solitary bees suggested to programs of controlled pollination was Centris analis, because of its constancy and abundance in Brazil. Several studies have shown the importance of C. analis in the pollination of some crops, and some papers brought information on the biology of this species. However, it still lacks information about factors that can increase or decrease C. analis population. Hence trap-nests made of black cardboard were offered in the campus of Universidade de São Paulo Ribeirão Preto from October of 2010 to September of 2012. The trap-nests measured 0.6cm in internal diameter and 6, 7, 8 and 9cm in length. Five hundred nests were obtained during the study period. From these nests emerged 369 females and 562 males of C. analis, and the immature mortality occurred due the parasites Leucospis sp. (100), Coelioxys sp. (55), Anthrax sp. (3), probably fungi (107) and unknown causes (100). Trap-nests with 6 and 7cm had up to four cells, and nests with 8 and 9cm had up to six cells, the most used length of trap-nest was 8cm. Sex ratio was male biased, and it seems that the trap-nests lengths did not influence the sex ratio of this bee. Twenty-eight females of C. analis were monitored during their nesting activities that occurred from October 2010 to April 2012. These females worked in the trap-nests from 6 to 24 days. Five females showing behavior considered different from normal pattern had a parasitoid larva inside their abdomen. Three of them made additional deposits of oil on nests finished days before, which usually dont receive more materials; the other two females were collected after making a fake nest plug, when they close the nest entrance without building brood cells in it. The five females built normal nests during the first days of monitoring, but stopped building nests with brood cells and started to make behaviors considered as atypical. These behaviors suggest that females become sterile as the parasitoid larva grows, first because the loss of space to carry nectar to the nest, and later because the loss of internal organs. Before dying many C. analis, males and females, concealed themselves inside trap-nests, possibly by influence of the parasitoid. The dead bees found inside trap-nests have been collected from January 2008 to September 2012, totaling 186 bees, from where emerged 113 adult conopids, belonging to eight species. Most of them were found in the three first months of the year, period of the hosts higher activity. Therefore, the conclusion is that the lengths of trap-nests alone do not influence the brood sex ratio; mortality in nests occurred mainly because of Leucospis sp. attacks, fungi or unknown causes, and an important natural enemy of the adults C. analis are the conopids.

ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada<br>Historically, aircraft power monitoring has required the use of multiple signal conditioning functions to measure various parameters including voltage, current, frequency and phase. This information was then post processed to determine the characteristics of the 3-phase power quality on the aircraft. Recent developments in embedded DSP processors within signalconditioning systems provide the instrumentation engineer with expanded capabilities for realtime on-board power quality monitoring. Advantages include reduced space and bandwidth requirements and minimal wiring intrusion. For each phase, output data may include peak positive and negative voltages and currents, peak-to-peak, average and RMS voltages and currents, phase power (real and apparent), phase power factor, phase period (frequency), phase shift measurement from phase 1 (the reference phase) to phase 2, and from phase 1 to phase 3. In addition, a Fast Fourier Transform (FFT) is performed on each phase voltage to provide Total Harmonic Distortion measurements. This paper describes the methods employed in the implementation of these functions on a single signal-conditioning card in order to provide detailed information about the power quality of a three-phase aircraft power source.

Abstract:
The purpose of this dissertation was to explore the potential use of net impulse and its characteristics in vertical jumping to monitor athletes' performance status and responses/adaptations to interventions. Five variables were proposed as net impulse characteristics: net impulse height and width, rate of force development, shape factor, and net impulse proportion. The following were then examined: 1) test-retest reliability of a new approach to identify net impulse in a force-time curve and of net impulse characteristics and criterion validity of the new approach; 2) effective measures of net impulse characteristics; 3) relationships between training-induced changes in its characteristics and force production ability. The following are major findings of the dissertation. Rate of force development particularly for the countermovement jump require a large magnitude of change to overcome the variable's inherent variability. Shape factor and net impulse proportion for the static jump should be used with caution and requires further investigations. Alternative net impulse can be used interchangeably to criterion net impulse. Of the proposed net impulse characteristics, net impulse height and width and shape factor were found to contribute to countermovement jump height, whereas all the net impulse characteristics were found to contribute to static jump height. Of the characteristics found to contribute, relative net impulse height (net impulse height divided by system mass) appears to be an important characteristic to achieve a high jump height for the countermovement and static jumps and net impulse proportion for the static jump. A mechanism behind increased countermovement jump height may be an increased countermovement displacement as a result of increased force production ability. A mechanism behind increased static jump height is the increased proportion of the entire positive impulse occupied by net impulse (i.e. increased net impulse proportion). The findings of this dissertation show the possibility of the use of the net impulse characteristics to monitor athletes' performance status and responses/adaptations to interventions. However, because this dissertation was the first to explore the potential use of the net impulse characteristics for athletes' performance monitoring, the existing knowledge is still preliminary and further research is required before practical recommendations are made.

Abstract:
<p>The Frequency Disturbance Recorder (FDR) is a specialized data acquisition device designed to monitor fluctuations in the overall power system. The device is designed such that it can be attached by way of a standard wall power outlet to the power system. These devices then transmit their calculated frequency data through the public internet to a centralized data management and storage server. </p><p> By distributing a number of these identical systems throughout the three major North American power systems, Virginia Tech has created a Frequency Monitoring Network (FNET). The FNET is composed of these distributed FDRs as well as an Information Management Server (IMS). Since frequency information can be used in many areas of power system analysis, operation and control, there are a great number of end uses for the information provided by the FNET system. The data provides researchers and other users with the information to make frequency analyses and comparisons for the overall power system. Prior to the end of 2004, the FNET system was made a reality, and a number of FDRs were placed strategically throughout the United States. </p><p> The purpose of this thesis is to present the elements of a new generation of FDR hardware design. These elements will enable the design to be more flexible and to lower reliance on some vendor specific components. Additionally, these enhancements will offload most of the computational processing required of the system to a commodity PC rather than an embedded system solution that is costly in both development time and financial cost. These goals will be accomplished by using a Field Programmable Gate Array (FPGA), a commodity off-the-shelf personal computer, and a new overall system design.</p><br>Master of Science

Abstract:
This thesis focuses on the manufacturing, indoor characterisation and outdoor monitoring of Perovskite solar cells (PSCs) and Organic photovoltaics (OPVs). In order for emerging PV technologies to become commercially viable it is important that their performance under these conditions is defined. In this thesis, the outdoor performance parameters of PSCs and OPVs monitored over the course of several campaigns are reported and benchmarked against polycrystalline silicon (poly-Si) solar cells. The data has been analysed in detail against solar irradiance dose, climatic conditions and stability. It was discovered that in common with poly-Si PVs, PSCs also exhibits a distinctive negative temperature coefficient across all performance parameters (VOC, ISC, FF and PCE) which decreases with increasing irradiation dose. In all outdoor campaigns the main causes for early-life degradation were noted to be sealant failure leading to oxygen and water ingress, although longer-term degradation has been observed and assigned to photo-oxidation which in some cases was effectively suppressed by the utilisation of UV filtering. The stability of PSCs and active layers was improved by the use of luminescent down-shifting coatings which were applied as a substitute to conventional UV filters. This thesis also demonstrates the benefit of multidirectional orientation of OPVs laminated onto an industrial building prototype for building-integrated applications. It is shown that positioning OPVs to more directions than South improves the overall diurnal yield and can potentially double the energy produced per year, in particular for peak generation hours in the UK. The benefit of unreacted lead iodide as partial filter to the highly damaging UV component of sunlight is shown. The importance of a thin residue lead iodide layer in PSCs shows an improvement in the stability of fabricated devices. One of the most significant findings in this thesis is the first report on the stability of perovskite absorber layers and solar cells conducted with irradiance levels at 1sun or 100sun concentrated natural sunlight. By accelerating the aging process, this method provides invaluable information about the long-term performance of absorber layers and devices which is an immense contribution to the PV community in improving the compositions and structure of PSCs. The stability of 3rd generation PV remains a critical issue preventing the appearance of these new and exciting, flexible and highly efficient PVs on the market. The last part of this thesis shows the second important finding in this thesis which focuses on an in-depth study of the stability of OPVs subjected to a multi-stress accelerated lifetime testing (ALT). This study is conducted indoors which facilitates the most destructive elements to the life of an OPV exposed outdoors to be clearly determined by exposing the modules to well-defined exposure conditions.

Abstract:
The loggerhead turtle (Caretta caretta) is the most abundant sea turtle species in the Mediterranean Sea. In 2023, 454 nests were identified along Italian beaches, these results represent the absolute Italian nesting record. It was also an exceptional year (2023) for Tuscany, in the central of Italy, where 24 nests were found. This area of central Italy seems to be no longer an exceptional site, so it is necessary to organize monitoring activities in order to cover most of the Tuscan beaches where Caretta caretta could nest. Between the mouths of two rivers, the Serchio and the Arno, lies a natural park, owned by the Tuscany Region, called the Migliarino San Rossore Massaciuccoli Natural Park (MSRM Park), a protected area with 34 km of protected coastline. With the aim of identifying, protecting and managing Caretta caretta turtle nests in this area, a monitoring program has been initiated using UAVs (Unmanned Aerial Vehicles), or drones, inside MSRM Park. In the first working season, which ran from June to August 2023, one carcass and some possible Caretta caretta tracks were identified, but no nest at the moment.

Abstract:
AbstractPakistan is a key country in China’s Belt and Road Initiative (BRI) where the China–Pakistan Economic Corridor (CPEC) is under implementation. An investment model of financing through loans, grants and private investments, CPEC is an example of South-South cooperation (SSC) having a number of benefits for both countries. Aimed at developing energy, industry, and communication infrastructure, the corridor initially valued at $46 billion but is now worth $62 billion. CPEC is expected to contribute significantly to socio-economic development and regional connectivity and trade. The main research question is, while implementing projects in Pakistan, to what extent China adheres to its avowed principles comprising features such as mutual respect, non-conditionality, equality, building local capacity and addressing actual needs of partner countries. Based mainly on the analysis of primary data collected during fieldwork in Pakistan, this research explores the extent to which the official narrative influences the actual practice of China’s development cooperation on the ground. To critically examine CPEC, this chapter uses a monitoring and evaluation framework developed by the Network of Southern Think Tanks (NeST), which is dedicated to generating systematic and clearly comparable knowledge on SSC (Besharati et al. 2017). The findings illustrate that, as per the five broad dimensions of the SSC framework, the China–Pakistan partnership under CPEC has performed well in the four areas of inclusive national ownership, horizontality, self-reliance and sustainability, and development effectiveness, but it has lagged in accountability and transparency.

Abstract:
In this paper, an algorithm is developed for the robot to take odometry combined with LiDAR (Light Detection and Ranging) input to perform localization and 3D mapping inside a swiftlet house model. The position of the walls in the swiftlet’s house for calibrating LiDAR data is obtained beforehand and the robot system would superimpose the LiDAR map and swiftlet’s nest to the provided global swiftlet house map. The LiDAR is able to generate a 2D map from point clouds with its 360-degree scan angle. Additionally, it is mounted to a 1 DOF arm for height variation thanks to a Stepper motor to achieve a 3D map from 2D layers. Swiftlet’s nests are detected by differentiating their distinctive shape from the planar concrete wall, recorded by the robot, and monitored until they are harvested. When the robot is powered up, it can localize itself in the global map as long as the calibrating wall is in view in one scan. We evaluate the robot’s functionality in the swiftlet’s cell model with swiftlet’s nest scanned. We propose a bird nest-oriented Simultaneous Localization and Mapping (SLAM) system that builds a map of birds’ nests on wood frames of swiftlet houses. The robot system takes 3D point clouds reconstructed by a feature-based SLAM system and creates a map of the nests on the house frame. Nests are detected through segmentation and shape estimation. Experiments show that the system has reproduced the shape and size of the nests with high accuracy.

We reviewed current (2008-2023) protocols for monitoring American alligator nests in Everglades National Park (ENP) using a qualitative statistical review framework that emphasizes connecting measurable objectives with evaluation of survey design elements. Our review outlined the statistical assumptions that, if severely violated, would prevent defensible inferences from being drawn regarding the three alligator nesting metrics monitored in ENP’s systematic reconnaissance flight (SRF) surveys: nest effort (number of nests), nest distribution, and nest fate. After evaluating the current survey and inference methods, we offer potential adjustments or augmentations to the design and models currently used to better account for potential error sources and align the stated objectives with statistical inferences.

Emmons, Gavin. Prairie and peregrine falcon occupancy and productivity monitoring at Pinnacles National Park: 2023 annual report. National Park Service, 2024. http://dx.doi.org/10.36967/2302448.

Full text
Abstract:
Pinnacles National Park (?Pinnacles?) provides diverse habitats for numerous cliff-nesting raptors, including prairie falcons (Falco mexicanus) and peregrine falcons (F. peregrinus), as well as a spectacular array of summits and cliff-wall routes for rock-climbers. This monitoring program was established to determine long-term trends in the number of occupied territories and productivity of nesting prairie and peregrine falcons. The monitoring program grew out of a need to reduce potential disturbance that climbers and off-trail hikers may have on cliff-nesting raptors. The falcon monitoring program began with a pilot effort in 1984, and after two years of no monitoring efforts in 1985 and 1986, monitoring data have been collected annually from 1987 to the present. This report summarizes the results from the 2023 breeding season and represents the 38th year of monitoring at the park, consistent with the standardized methods and procedures detailed in the Prairie Falcon Monitoring Protocol for Pinnacles National Monument (Emmons et al. 2011). To monitor falcons, field technicians surveyed all potential nest sites three times per breeding season, with visits spaced 21 to 28 days apart. We revisited those nests determined to be active to confirm rearing of nestlings and fledging of young. In 2023, we conducted monitoring from 1 January 2023 until 9 July 2023, with a total of over 150 possible and active nest sites monitored during 870 observation hours. For prairie and peregrine falcons combined, we documented 14 territorial pairs this year, with 12 pairs actively nesting. Six nests successfully fledged 17 young; six nests failed. For prairie falcons specifically, we documented ten territorial pairs, with three nests successfully fledging 10 young. For peregrine falcons, we documented four territorial pairs, with three nests successfully fledging 7 young. Falcon fecundity for the 2023 season was notably lower compared to the 37-year average. The data from 38 years of falcon monitoring at Pinnacles suggest an apparent cyclic population pattern in annual prairie falcon productivity, supplemented by increased peregrine falcon breeding efforts in recent years (Appendix C).

Full text
Abstract:
Breeding colonies of wading birds (orders Ciconiiformes, Pelecaniformes) and seabirds (orders Suliformes, Pelecaniformes) serve as important indicators of aquatic ecosystem health, as they respond to changes in food abundance and quality, contaminants, invasive species, and disturbance. The Comprehensive Everglades Restoration Plan, Restoration Coordination &amp; Verification program (CERP-RECOVER) has identified wading-bird colonies as an important ecosystem restoration indicator. The National Park Service South Florida/Caribbean Inventory &amp; Monitoring Network (SFCN) ranked colonial nesting birds eighth out of 44 vital signs of park natural resource conditions for ecological significance and feasibility. However, while large-scale monitoring efforts are occurring in the rest of the Greater Everglades Ecosystem, only minimal historic data collection and no extensive ongoing monitoring of wading bird and seabird nesting have occurred in Biscayne National Park. Consequently, due to their high importance as biological indicators and because they are a gap occurring in regional monitoring efforts, the network has initiated a monitoring program of colonial nesting birds in Biscayne National Park. This protocol provides the rationale, approach, and detailed Standard Operating Procedures for annual colonial bird monitoring within and close to Biscayne National Park and conforms to the Oakley et al. (2003) guidelines for National Park Service long-term monitoring protocols. The specific objectives of this monitoring program are to determine status and long-term trends in: Numbers and locations of active colonies of colonial nesting birds with a special focus on Double-crested Cormorants, Great Egrets, Great White Herons, Great Blue Herons, White Ibises, and Roseate Spoonbills. Annual peak active nest counts of colonial nesting birds in Biscayne National Park with a special focus on the species mentioned above. An annual nesting index (i.e., sum of monthly nest counts) with a special focus on the species mentioned above. Timing of peak nest counts for the focal species.

Full text
Abstract:
Harpers Ferry National Historical Park (NHP) includes grassland habitats that are maintained for the interpretation of historic Civil War battles. In 2022, as part of the National Park Service Inventory and Monitoring program, the University of Delaware conducted a grassland bird and raptor inventory in the park. The goals of this inventory were to determine the grassland bird use of Harpers Ferry grasslands during Spring and Fall migration, estimate the abundance and daily nest survival for focal breeding species, and determine the raptor use during migration. We established and used multiple avian sampling techniques to address these goals including distance sampling using line transects, mist-netting to capture passerine birds, point counts, hawk watching, and nest searching and monitoring. We conducted this inventory during the annual cycle starting in March 2022 and completed the sampling in October 2022. During the course of this effort, we detected 111 species using the Harpers Ferry grasslands at some time during the year. We found that the park is supporting migrating and breeding grassland birds and that the avian species composition changes over the course of the annual cycle. During migration, we detected focal grassland bird species including Bobolink, Savannah Sparrow, Grasshopper Sparrow, and Eastern Meadowlark. During the breeding season, we located and monitored Eastern Meadowlark and Grasshopper Sparrow nests with adequate sample sizes to estimate daily nest survival. We found that Eastern Meadowlark daily nest survival was relatively high (99%) and was influenced by the proximity of the nest to a forested edge. We recommend the park focus on Eastern Meadowlark and Grasshopper Sparrows as these two species used the park during both Spring and Fall migrations and successfully fledged young during the breeding season. The park could attempt to maintain or enhance Eastern Meadowlark and Grasshopper Sparrow use of the park during all stages of the annual cycle but especially during the breeding season. This could be achieved by continuing to keep the existing breeding areas intact through delayed mowing (no mowing from 15 May ? 15 July), removing tree lines and woody or non-native vegetation to increase the perceived openness and grassland patch size, and continuing to monitor the effects of any management actions that may influence grassland bird use of Harpers Ferry NHP. Grassland birds are a national conservation priority so any sites that have the capacity to maintain or enhance these declining habitat specialists should do so. Grassland birds provide an opportunity to integrate cultural and natural resources as these birds were most certainly present prior to, during, and after the Civil War Battles that Harpers Ferry was established to commemorate.

Northwestern pond turtles have gained much attention in the past few decades due to dramatic population declines.

To build on that past data and better understand current pond turtle distribution, abundance, non-native co-inhabitants, demographics, nesting behavior, and nest site characteristics, we conducted distribution surveys here from 2015?2019. We found northwestern pond turtles using visual encounter and trapping surveys at 11 sites, mostly confirming past USGS observations at those sites. However, we detected pond turtles in only 38% of sites previously identified by USGS as having pond turtles. In our surveys, pond turtles were most abundant at two Martinelli ponds along the southeastern slopes of Tomales Bay. At this location, we have an estimated population size of 94 adults (carapace length range from 68 to 300) from mark-recapture trapping surveys. This site is also the largest nesting population in the park, with annual nest abundance of 13.75 nests per year and a mean clutch size of 4.9 eggs per nest. The demographic data from the Martinelli Ponds indicates a population skewed towards larger individuals, which is consistent with other locations elsewhere in California. This population data served to identify the Martinelli Ponds population as the donor site for a GOGA pond turtle headstart project. Nesting activity in 2017?2019 occurred from late May with activity peaking in mid-June and tapering off in mid-July. Visual surveys proved to be the most effective means of finding nesting females and nests; camera traps, VHF telemetry, and PIT antenna array costed time and money while not providing the desired information. Future inventory efforts should focus on resurveying lightly surveyed sites where we were not able to find northwestern pond turtles, periodic monitoring of abundance and demographic structure of main PORE population (Martinelli Ponds), and surveillance monitoring for invasive bullfrogs and turtles. Increasing public awareness of the status of northwestern pond turtles is another key action that will play a major role in their conservation.

Abstract:
The habitats within Biscayne National Park consist of rocky coast lines, Biscayne Bay (a shallow water bay), over 40 mangrove islands, and coral reefs. This ecosystem lies near the large metropolitan area of Miami, suburban development, a nuclear power plant, and has several canals that drain from the mainland into Biscayne National Park or close to park boundaries. As a result of the park?s proximity to a large population, it endures heavy usage. The park is a popular destination for anglers and boaters. All the aforementioned factors put stressors on the park ecosystem. The South Florida/Caribbean Network has developed a long-term monitoring program that focuses on the colonial nesting birds that use park resources for foraging, roosting, and nesting. The South Florida/Caribbean Network uses monthly helicopter flights to survey nine nesting colonies in or near the park. The nine colonies monitored are: Kings Road, Mangrove Key, West Arsenicker Key, Arsenicker Key, Jones Lagoon, Ragged Key 4, Ragged Key 5, Soldier Key, and Kings Bay. We focus on six species of birds: double-crested cormorants (Phalacrocorax auritus), great egrets (Ardea alba), great white herons (Ardea herodias occidentalis), great blue herons (Ardea herodias), white ibises (Eudocimus albus), and roseate spoonbills (Platalea ajaja). Data collection for this vital sign began in 2009. This report presents data regarding peak nesting, nesting indices, species abundance, and the nine nesting colonies. No forecasts are presented from the data collected in this report. Peak nest counts for five of the six focal species were lower in 2021?2022 than 2020?2021, except for white ibis, which increased relative to the previous nesting season. For the fourth consecutive season, peak nest counts for double-crested cormorants remain under 1,000 nests. For the number of species actively nesting by colony, our data indicate that two colonies increased, four colonies decreased, and three colonies remained the same relative to the previous nesting season. At least one of the focal species nested at all nine colonies, which has been consistent since the start of surveys.

Abstract:
Survey vehicles, operating at traffic-speed, are deployed across the road network to assess the condition of road pavements. These apply high-quality (and high cost) equipment to measure condition. However, significant progress has been made in the development of low-cost sensors and data collection units that may have potential for application in highways. This project has aimed to understand the capabilities of this emerging technology. The project explores the technologies and combines a Raspberry-Pi based Data Acquisition System, compact camera, GPS, inertial measurement system, Wifi and 4G GSM comms and a low-cost Solid State LiDAR into a prototype device. The total cost is a few hundred pounds. Trials characterise the prototype system. Although the solid-state LiDAR sensors are not found to be robust in this application, the remaining sensors show strong potential for use in road condition assessment. A wider trial of the prototype system in a potential application – the measurement of roughness (IRI) on developing world road networks – was carried out in El Salvador. The prototype shows comparable performance with alternatives, combined with higher levels of practicality and capability, and the potential for higher levels of consistency through a common low-cost measurement platform. In the light of this research, it is felt that, following refinements to the prototype, the initial application for the device would be for condition surveys in developing world nations.
