After a brief review of floristic classifications, ecological survey, as carried out in Quebec, is described. Three stages of development of ecological survey over the past twenty-five years are identified: (1) the pioneer work of Jurdant; (2) major ecological surveys from the late 1960s to the late 1970s; and (3) the diversification of the groups involved in ecological land surveys beginning in the 1980s, including universities, the Quebec Environment Department (MENVIQ) and the Quebec Department of Energy and Resources (MER). Intended for use in integrated land management, ecological survey must be an effective integrator of the various ecological evaluations; the information must be easily communicable and the methodology must be flexible. Ecological land classification has two dimensions: (1) taxonomic; and (2) cartographic. In the taxonomic units, the ecological region, the ecological type and the ecological phase are identified. In cartographic terms, local (ecological phase and type), regional (ecological system and subsystem) and national (ecological district and region) resolution is identified.Quebec universities, MER and MENVIQ are presently involved in ecological land surveys. The new Forest Act, which was enacted in 1986 and which provides for sustainable yield and more intensive forest management, is a major force behind the promotion of the use of ecological inventories as the basis for management activities. Mapping of the ecological regions (1:1,250,000) has almost been completed in Quebec. Total coverage of the commercial forest as a function of ecological districts (1:250,000) could be completed within five years, and the mapping of ecological types (1:20,000) could be completed in 20 years at a rate of 10,000 km2 a year. Although in the past ecological land surveys have been used primarily for environmental impact analyses (for instance, the installation of hydroelectric equipment and transportation corridors), the ecological framework is presently being used to prepare development plans for a number of regional county municipalities (RCMs). Pilot projects are under way to assess the potential applications of the ecological framework to forestry as part of intensive management efforts. Improvements are needed in both the accessibility of the information provided by the ecological framework (maps, site guides) and the development of interpretative tools for silvicultural measures. Key words: ecological survey, ecosystem mapping, ecological land classification, forest ecology, forest site classification, Quebec.

Purpose The article's purpose was to examine participants' impressions and experiences with smartphone-based ecological momentary assessment (EMA) to inform future EMA study design. Method Adults with hearing impairment (HI, n = 9) and with normal hearing (NH, n = 10) participated in a study using a smartphone-based EMA system to measure their auditory lifestyles. A 14-item survey was scheduled to deliver every 45 min by an EMA app. After a 1-week trial, participants were interviewed regarding their study experiences. The app log files were analyzed to understand how the participants interacted with the app. Results Across the two groups, 1,295 surveys were completed (compliance rate 74.4%). On average, HI participants completed 10.0 and NH participants completed 9.1 surveys per day. The mean survey completion time for HI and NH groups were 72 s and 51 s, respectively. For both groups, about 90% of the participants reported the app as easy to use; about 60% of the participants reported that repetitive surveys interrupted or somewhat interrupted their activities. Participants reported surveys disrupting situations, for example, working, driving, and social events, and that they were more likely to skip surveys in these situations. Additionally, 50% of NH and 30% of HI participants indicated that the survey was not delivered too frequently and none indicated that the survey was too long. Conclusion Overall, the app and EMA design seem to be appropriate. Insights from this study can help researchers design their studies to adequately assess listeners' experience in the field with optimal compliance and data quality.

Abstract Background Ecological momentary assessment (EMA) is a methodology involving repeated surveys to collect in situ data that describe respondents' current or recent experiences and related contexts in their natural environments. Audiology literature investigating the test-retest reliability of EMA is scarce. Purpose This article examines the test-retest reliability of EMA in measuring the characteristics of listening contexts and listening experiences. Research Design An observational study. Study Sample Fifty-one older adults with hearing loss. Data Collection and Analysis The study was part of a larger study that examined the effect of hearing aid technologies. The larger study had four trial conditions and outcome was measured using a smartphone-based EMA system. After completing the four trial conditions, participants repeated one of the conditions to examine the EMA test-retest reliability. The EMA surveys contained questions that assessed listening context characteristics including talker familiarity, talker location, and noise location, as well as listening experiences including speech understanding, listening effort, loudness satisfaction, and hearing aid satisfaction. The data from multiple EMA surveys collected by each participant were aggregated in each of the test and retest conditions. Test-retest correlation on the aggregated data was then calculated for each EMA survey question to determine the reliability of EMA. Results At the group level, listening context characteristics and listening experience did not change between the test and retest conditions. The test-retest correlation varied across the EMA questions, with the highest being the questions that assessed talker location (median r = 1.0), reverberation (r = 0.89), and speech understanding (r = 0.85), and the lowest being the items that quantified noise location (median r = 0.63), talker familiarity (r = 0.46), listening effort (r = 0.61), loudness satisfaction (r = 0.60), and hearing aid satisfaction (r = 0.61). Conclusion Several EMA questions yielded appropriate test-retest reliability results. The lower test-retest correlations for some EMA survey questions were likely due to fewer surveys completed by participants and poorly designed questions. Therefore, the present study stresses the importance of using validated questions in EMA. With sufficient numbers of surveys completed by respondents and with appropriately designed survey questions, EMA could have reasonable test-retest reliability in audiology research.

Abstract: starting with the works of V.I. Vernadsky, the history of the development of ideas about the interaction of the abiotic spheres of the Earth (upper lithosphere, pedosphere, lower atmosphere and surface hydrosphere) and the living (society, microorganisms, vegetation and land wildlife, hydrobionts (bacterioplankton, phytoplankton, zooplankton, macrobenthos)) is presented. The modern ideas about the content of the concept "ecological functions of abiotic spheres of the Earth", including the resource, geochemical, geophysical and geodynamic, involved in the resource and energy support of life and development of biota, are formulated. Three time stages of formation of the ecological functions of abiotic spheres of the Earth are allocated and characterized. It is shown that at the third technogenic-natural stage of development of these functions, when engineering-ecological surveys are carried out, at local sites, the consequences of technogenesis are leading in the assessment of the current state of ecosystems. The interaction of the lithosphere, pedosphere, surface hydrosphere, Earth's atmosphere with each other and the technosphere is described. The issues of necessity of taking into account perception of ecological functions of the Earth in the code of rules (SP) for engineeringecological surveys and the input of new terminology are considered. It is noted that each ecological function of the abiotic spheres of the Earth is characterized by a large number of indicators of private and complex properties, the study of which has long been mandatory during engineeringecological surveys. The statistics on the composition of the work on the study of the spheres of the Earth in the technical guidance documents of different years on engineering-ecological surveys is adduced. It is stated that in the current SP 47.13330.2016 “Engineering surveys for construction. Main provisions” in terms of engineering-ecological surveys, the vast number of characteristics of ecological functions of the abiotic spheres of the Earth, including the study and evaluation of modern geological processes affecting biota are taken into account. The recommendations on improvement of technical guidance documents for engineering-ecological surveys are formulated.

The vegetation of greenstone hills in the Kalgoorlie area of the Eastern Goldfields region of Western Australia was studied to identify the key environmental influences on community and species distribution. This information was needed to determine if plant communities of the hills could provide analogues for the rehabilitation of waste rock dumps that are produced as a consequence of open cut mining. The ridges, slopes and flats adjacent to the main slope were examined and the floristic data sorted into communities. Two structurally and floristically distinct alliances were identified, one dominated by eucalypt species and the other by Acacia quadrimarginea. The eucalypt woodland displayed a taller upper stratum and few groundlayer species and was the dominant vegetation of the flats at the base of the hills. The acacia community was a low woodland and is the dominant vegetation of the hill slopes. Both communities were dominant at an equal number of sites on the ridges of the hills. An investigation of the environmental variables found that edaphic, rather than topographic, factors were responsible for the community distribution on the hills. The eucalypt woodland showed a strong affinity to soils derived from calcrete, which had higher levels of electrical conductivity and lower exchangeable sodium percentages than the soils of the acacia low woodland. Under such conditions, the clay fraction of the soil remains in a more flocculated state allowing higher rates of water infiltration and hydraulic conductivity compared to the acacia soils. Soil nutrients were found to have a secondary influence on community distribution and had a greater effect on species distribution within alliances. A study of the seasonal variation in water content of the soils showed that more moisture is retained in the upper soil horizons in the acacia community than in the eucalypt community during the wetter part of the year, indicating the acacia soils had poorer infiltration properties than the eucalypt soils. The distribution of drought tolerant species such as A. quadrimarginea and Prostanthera incurvata was found to be correlated to soil moisture content of the dry season whilst no correlation was found for the eucalypts at any time of the year. Seasonal comparisons of leaf moisture content and xylem pressure potential showed that the eucalypts maintained their total leaf moisture content throughout the year whereas species such as A. quadrimarginea and Allocasuarina campestris recorded high levels of desiccation of their leaf tissue over the summer. The eucalypts also maintained a more consistent pre-dawn xylem pressure potential throughout the year than either A. quadrimarginea or the shrub species Dodonaea microzyga, indicating a greater degree of stomatal control and access to a more consistent soil water supply. The eucalypts require access to a greater soil volume than the acacias or shrubs in order to ensure sufficient water supplies for the maintenance of tissue moisture levels throughout the year. In this way, the eucalypts are able to effectively avoid the summer drought, whereas the acacias and shrubs are able to tolerate desiccation of their leaf tissues over this period. Investigations of the germination requirements and early seedling survival of prominent species from the greenstone hills indicated that fire may be a factor in the regeneration of most hills species. All studied species were either tolerant of or responded positively to the application of dry heat. In relation to seedling establishment on waste dumps, increasing the soil moisture content of waste dump soils increased the germination rate of most species but did not result in greater seedling survival at the end of the first summer. The provision of microsites which encouraged root development and provided protection for the young seedlings was found to be more important in reducing mortality rates in the first year than increasing the total germination. The study emphasized the importance of physical soil factors and the soil moisture regime in the distribution of eucalypt and acacia communities on the greenstone hills. A species' response to drought stress strongly influences its ability to compete for soil water on different soil types. The eucalypts studied in this project dominated on soils where there is better recharge of subsoil water reserves which can be accessed over the summer period to maintain tissue water levels. Acacias are tolerant of tissue desiccation and will compete successfully on shallower soils and where hydraulic conductivity is poor. Although the project was valuable in identifying water relations as the main control on community distribution on the hills, waste dumps are not strictly analogues of intact greenstone hills due to the differences in rock type and profile formation. Electrical conductivity levels are also higher due to extraction processes. However, the environmental relationships of the different species show that the more drought tolerant species such as Allocasuarina campestris, Acacia quadrimarginea and understorey species associated with them, may be suitable species to form the basis of vegetation reinstatement on waste dumps in the Kalgoorlie region.

In the study of ecological community structure, the multivariate niche model has always been the assumed structural model. This model is closely connected to the multivariate two-sample problem. Important to the understanding of species interactions in a community is the measurement of the degree to which the niches of two species overlap, or to measure the similarity between the resource use distributions of the species. Discriminant analysis is the tool used most often to analyze the similarity. In this study, we discuss the most commonly used similarity measures, and develop measures that are less dependent on the assumptions of the usual discriminant analysis. Specifically measures arc derived assuming normal distributions with heterogeneous variance-covariance matrices arc derived. The problem of estimating the measures and their precision and accuracy is investigated. Two methods, the jackknife and the bootstrap, arc described for estimating the bias and variance of an estimated measure. The performance of these methods was evaluated using simulation. When the number of variables involved in the model is large, the estimates of these measures may be severely biased, and the bias is consistently negative. By collecting larger samples the bias can be reasonably adjusted. Two potentially important factors affecting results arc the disparity in the means and the heterogeneity of the variance-covariance matrices. It is shown that when the mean separation is small, the heterogeneity of the covariance matrices has a moderate effect on the bias, but the effect is diminished when the mean separation becomes larger. The variance of the similarity estimates is also related to the value of the measure and is a quadratic function of the similarity. The logarithmic transformation of the similarity is seen to linearize the variance of the similarity estimate. The jackknife method gives good adjustment of the bias of the estimated measures. Generally, the bootstrap method performs worse than the jackknife method. In some cases, especially when there are many redundant variables neither method gives reliable results.

Resumo:
Longline fishing is the most common elasmobranch capture method in the world, both for commercial fishing, and to a lesser extent for scientific surveys. The capture of an animal on a longline initiates a series of physiological responses designed to promote survivorship in the short term, but if unchecked, can cause reduced individual fitness and/or mortality in the long term. Given widespread declines in shark populations, an improved understanding of the physiological costs of longline capture is needed. The aim of this thesis was to investigate the physiological response of sharks to capture and restraint, to assess novel, non-invasive alternatives to scientific longline surveys, and to generate scientific insight into poorly understood elasmobranch populations in The Bahamas. The results presented herein suggest that some species of shark are able to recover from the physiological stress of capture despite the presence of persistent negative stimuli. Tonic immobility was assessed as a means of generating baseline blood chemistry data, but was found to be inappropriate given that it increases the magnitude of physiological perturbation in the short term. To avoid the stress of capture altogether, Baited Remote Underwater Video Surveys (BRUVS) were considered as a non-invasive alternative to capture based surveys, however, it was concluded that they lack the resolution necessary to answer fine scale demographic questions. For the Caribbean reef shark, longline surveys yielded high resolution data allowing the identification of fine scale spatiotemporal shifts in demographic population structure with minimal cost (mortality). Nevertheless, the ethics of using capture based surveys on sensitive species are questionable when alternative techniques are available. Deep water sharks caught on longline surveys exhibited high mortality rates, however, for these very poorly understood species moribund specimens have great scientific value which in some cases can offset the high ecological costs of the surveys. The results presented in this thesis highlight the on-going need for improved biological and ecological research into the majority of elasmobranch populations, particularly with regards to anthropogenic interactions such as capture. Given the tenuous conservation status of many species, the acquisition of applied, management focused data should remain the priority of elasmobranch scientists.

Bibliography: pages 71-83.
A variety of studies have shown the problems of energy supply faced by low-income communities in southern Africa. Most of these communities are dependent upon indigenous fuelwood supplies. In addition, many of these communities use indigenous wood for construction. This largely uncontrolled utilisation imposes severe threats on woody vegetation communities. The Eastern Cape/Ciskei region is an area where energy supply problems are particularly severe and impacts on woody vegetation correspondingly severe. This study aimed to investigate the feasibility of using remote sensing techniques to monitor the the impact caused by collection of wood in the Eastern Cape/Ciskei forest and thicket communities. A variety of remote sensing techniques for landcover analysis were investigated. In all cases, visual interpretation was used because it is considerably cheaper and demands less technical expertise than would computer processing. In addition, many studies have shown visual interpretation to be superior. Maps were drawn from multitemporal aerial photograph sequences and from Landsat and SPOT satellite images. These maps showed that there has been relatively little change in area of woody vegetation in the study area since 1956. However, field studies showed that vegetation community structure had been degraded as a result of intense and sustained human impact. This qualitative decline also reflected a decline in usefulness of the woody vegetation of the area to local communities. This substantial degradation was not visible on any of the remote sensing imageries. This emphasises that field-based checks to monitor human impacts on forest and thicket formations are essential. Strategies for reducing the dependence of low-income communities on indigenous vegetation for energy supplies and constructional timber have been reviewed from the literature and these are descibed in Appendix 1. Most successful strategies in other parts of the world have been the result of a national commitment to tree planting, recognition of a multiplicity of constraints and the voluntary involvement of the communities the strategies are intended to assist.

AbstractThis chapter provides an overview of the theoretical approaches to environmental attitudes and behaviors. It includes a discussion of different scales and surveys used in other programs with a focus on this topic. Scales measuring general environmental behavior, just like items in surveys, tend to focus on behavioral intentions and are correlated with environmentally friendly attitudes. In contrast, emission-related behavior depends more on context and socio-demographic characteristics and is rarely asked in surveys. Gaps frequently occur between environmental attitudes and general behaviors—the value-action gap—and between environmental behaviors and the actual ecological consequences of actions—the behavior-impact gap. Finally, previous results and problems encountered in the validation of self-reports on environmental behavior are highlighted.

AbstractCurrent urban development practices are predicted to be largely unsustainable, placing an increasing burden on surrounding ecological systems. One mitigation effort involves expanding green infrastructure and alleviating urban ecological challenges by building in cooperation with ecological processes. Cities are investing in large-scale green infrastructure projects such as urban parks, bioswales (roadside plantings), and green roofs. Recently, scientists have begun to explore the ecological principles that govern the assembly and long-term performance of rooftop communities. In Fall 2013 and Spring 2017, students in the Microbiology and Molecular Biology laboratory courses at Barnard College engaged in surveys of soil microbial communities from different types of green infrastructure installations to evaluate the factors that structure community assembly. These projects enabled students to witness and contribute to developing urban ecological sustainability measures. The results contributed to a successful grant application, a Master’s thesis, and several peer-reviewed publications with students as lead or co-authors. Two students, inspired by their exposure to green infrastructure, demonstrated the negative impacts of nitrogen deposition on sensitive roadside green infrastructure installations. Students expressed an increased feeling of ownership and pride due to the authenticity and novelty of their work and increased engagement with both the course project and ecological sustainability.

AbstractA project entitled, “Building village economies through climate farming & forest gardening” (BeChange) was implemented in four municipality areas of the Tanahun and Lamjung districts of Nepal from May 2015. In order to assess changes in the social-ecological system that result from this project targeting abandoned agricultural lands, this case study was conducted using various methods: triad grouping, GPS point surveys, household surveys, focus group discussions (FGDs), field observation and reports. A participatory approach in reforestation on abandoned agricultural land with introduction of carbon credits has become a new livelihood strategy for local communities. It has not only attracted domestic and international tourists, but also helped to conserve biodiversity and local ecology. This activity also united village women and indigenous communities as triad groups for collaborative outcomes. A total of 42,138 seedlings of mixed tree species such as Michelia champaca, Elaeocarpus ganitrus, Bassia butyraceae, Bauhinia purpurea, and Cinnamon tamala were planted by 276 families on abandoned agricultural land between May 2015 and July 2018. However, as of 2020, this range has expanded to include 635 families with plantations of more than 65,000 seedlings. The set-up and maintenance of these forest gardens were financed with advanced payments for the carbon sink services of the planted trees. Farmers who succeeded with tree survival rates above 80% received an additional yearly carbon sink payment. The outcomes of the project show significant improvements in food security and tree biodiversity in the project villages. Of the total sampled households, almost half (45%) were under extreme poverty and had food sufficiency for only 3 months/year before the project. With the project, this percentage dropped to 22%, signals the emergence of seeds for transformative change.

AbstractThe oceanic islands of the Gulf of Guinea (Príncipe, São Tomé, and Annobón) are an exceptional centre of endemism for flora and fauna. Remarkable progress has been made in biological research during the last few decades: from species being described and reported for the first time, to general patterns of species-habitat associations found across terrestrial, coastal, and marine taxa. Despite this increase in knowledge, key aspects of Gulf of Guinea species ecology remain poorly understood. This chapter reviews existing knowledge on the biodiversity of the islands, focusing on species distributions, population abundance estimates, traits, habitat associations and interactions. To promote these islands as ecological models, and to ensure the future of their endemic-rich biodiversity, it is essential to overcome current knowledge gaps and reduce existing taxonomic, spatial, and temporal biases in the information available. Therefore, future studies should favour systematic island-wide surveys and prioritize understudied areas and taxonomic groups. Moreover, long-term monitoring studies are urgently needed to assess biodiversity trends and to advise conservation actions. The future of ecological research and conservation of the unique biodiversity of these islands must increasingly rely on the development of local biodiversity-focused scientific expertise, through outreach, capacity building, and advanced training, paired with international collaborations and the development of local organizations.

ZusammenfassungDer Ausbau der Windenergie findet zunehmend im Wald statt, da hier häufig windhöffige und damit ökonomisch attraktive Standorte zu finden sind. Allerdings ist hier der Konflikt mit dem Artenschutz im Allgemeinen und dem Fledermausschutz im Speziellen besonders hoch. In diesem Beitrag beleuchten wir vor dem Hintergrund des gesetzlich vorgegebenen normativen Rahmens den artenschutzrechtlichen Teil der Windkraftplanung im Wald mit Bezug auf Fledermäuse – von der Untersuchungsplanung über die eingesetzten Methoden bis zur Bewertung. Bezogen auf Fledermäuse stehen hier insbesondere die Vermeidung der direkten Tötung sowie die Verminderung der Beeinträchtigung ihres Lebensraums im Fokus der Betrachtung. Bundesland-spezifische Arbeitshilfen stecken den Untersuchungsumfang, die einzusetzenden Erfassungsmethoden und den räumlichen und zeitlichen Untersuchungsrahmen ab. Sie empfehlen zudem Maßnahmen zur Kompensation potenziell negativer Auswirkungen eines Eingriffs. Ihr Effekt auf die methodische Qualität der Fachbeiträge zu Fledermäusen ist jedoch gering. Meist kommen im Rahmen der speziellen artenschutzrechtlichen Prüfung zu Fledermäusen die Quartierbaumsuche, Netzfang, unterschiedliche Varianten des akustischen Monitorings (aktiv und passiv) sowie die Radiotelemetrie zum Einsatz. Insbesondere bei der bevorzugt empfohlenen akustischen Erfassung mindern zahlreiche methodische Probleme auf der technischen und der analytischen Ebene die Aussagekraft. Auch der Erfolg des Fangs von Fledermäusen mit Netzen hängt von zahlreichen Parametern ab. Die Quartierbaumerfassung lässt sich in ihrem Erfolg deutlich durch die Radiotelemetrie verbessern. Zur sinnvollen Quantifizierung des Lebensraumanspruchs einer Fledermauspopulation jedoch werden mittels Radiotelemetrie in der Regel zu wenige Tiere zu kurz untersucht. Die Bewertung der erhobenen Daten, hier gezeigt anhand akustisch ermittelter Aktivitätsdichten, erfolgt subjektiv, da Bewertungskriterien fehlen. Die am häufigsten empfohlenen und somit umgesetzten Methoden der Konfliktvermeidung und -minimierung sind CEF- (= Continued Ecological Function) und FCS-Maßnahmen (= Favourable Conservation Status) sowie das Gondelmonitoring und die selektive Abschaltung der WEA. Auch diese Maßnahmen entfalten z. T. Schwächen; die Bewahrung und Entwicklung von Waldstandorten als/zu ökologisch wertvollen Lebensräumen sowie die Verminderung der Schlagopferzahl durch spezielle Algorithmen (ProBat-Tool) sehen wir jedoch als sinnvoll an. Abschließend formulieren wir Anregungen zur Verbesserung und Objektivierung der Eingriffsplanung von WEA im Wald.SummaryThe development of wind energy is concentrating in forests, as windy and thus economically favourable sites can often be found here. However, the conflict with species conservation in general and bat conservation in particular is especially high in forests. We here examine the impact assessment on bats in the context of the legally prescribed normative framework in wind farm planning in the forest – from the study design to the methods used and the assessment itself. With regard to bats, the focus here is on avoiding direct killing and reducing the impairment of their habitat. Guidance documents for the German federal states define the extent of the surveys, the survey methods, and the spatial and temporal scope of a survey. They also recommend measures to compensate for potential negative impacts of wind energy plants (WEP). However, their effect on the quality of the expert reports on bats is low. In most cases, the search for roost trees, mist netting, different types of acoustic monitoring (active and passive) and radio tracking are used. In particular, numerous methodological problems at the technical and analytical levels reduce the validity of acoustic surveys. The success of mist netting bats also depends on numerous parameters. The success of roost tree surveys can be significantly improved by radio tracking. However, for a meaningful quantification of the habitat requirements of a bat population, radio tracking is usually used on too few animals for too short a time. The evaluation of the collected data, shown here on the basis of acoustically determined activity densities, is subjective because evaluation criteria are lacking. The most frequently recommended and thus implemented methods of conflict mitigation are CEF (= Continued Ecological Function and FCS (= Favourable Conservation Status) measures as well as nacelle monitoring and selective shut-down of wind turbines. These measures also show some weaknesses, but we consider the maintenance and development of forest sites as or into ecologically valuable habitats, as well as the reduction of the number of bat fatalities by means of specific algorithms (ProBat tool), to be sensible. Finally, we make suggestions for improving and objectifying the impact assessment of wind-energy facilities in forests.

AbstractTermites are the major ecosystem service providers and contribute significantly to soil processes and nutrient cycling in tropical ecosystems. The ecological services provided by termites are often discredited due to their commonly-regarded status as pest in human-dominated landscapes, however. In order to understand the potential roles of termites in peatland ecosystems, termite samplings were conducted in abandoned degraded peatland and peatland cultivated with oil palm in Riau, Sumatra. Surveys found a total of six species of termite of the family Rhinotermitidae. (rhinotermitid) in study plots of disturbed lands. In particular, Coptotermes spp. are notorious pests to oil palm, and may also be a potential pest in indigenous tree replanting programs. Based on analysis of termite feeding groups and documentation of wood susceptibility to termite attack, this study provides a reference of tree species that must be avoided in indigenous tree replanting programs so that the trophic relations of termite populations are of most benefit to peatland soil biodiversity and thereby to resilient peatland ecosystems.

Many ecological studies and conservation policies are based on field observations of species, which can be affected by systematic variability introduced by the observation process. A recently introduced causal modeling technique called 'half-sibling regression' can detect and correct for systematic errors in measurements of multiple independent random variables. However, it will remove intrinsic variability if the variables are dependent, and therefore does not apply to many situations, including modeling of species counts that are controlled by common causes. We present a technique called 'three-quarter sibling regression' to partially overcome this limitation. It can filter the effect of systematic noise when the latent variables have observed common causes. We provide theoretical justification of this approach, demonstrate its effectiveness on synthetic data, and show that it reduces systematic detection variability due to moon brightness in moth surveys.

The results of cartographic modeling of the temperature fields of soils of the land fund of the Novosibirsk region using satellite data obtained by the MODIS/Terra spectroradiometer are considered. The developed cartographic models give a clear idea of the spatial structure of the temperature fields of the soil cover of the Novosibirsk region and the qualitative changes in the temperature regime of soils in different years. According to the data of daytime and nighttime surveys, the peculiarities of the temperature distribution of the soil cover for 2001 and 2010 were established. The values of the average annual temperature of the underlying surface for 2001–2014 were calculated. It is assumed that thermal resources not reflected in the generalization of zonal zoning can be identified on cartographic models. These resources have independent ecological significance and characterize the diversity of landscape, anthropogenic and other types of climate.

The reuse of assembly equipment allows the exploitation of its unused potential, thus complying with both the economic objective of a high level of cost efficiency and the ecological objective of a high level of resource efficiency. Surveys have revealed manifold challenges for practitioners. Lack of experiences with the reuse process, the insufficiently designed and prepared equipment, missing life-cycle documentation as well as missing holistic planning concepts for the reuse where identified as main obstacles. In order to meet these challenges, a framework consisting of methods, tools and business process reference models for assembly equipment reuse is proposed. The core element is a computer aided reuse planning application that allows planners to generate reuse options and provides decision support during the planning process. The knowledge based approach, including its structure and core inference processes, which support the application is explained. The service oriented architecture for the realization of the framework is presented.

In Korea, recycling of garbage has been emphasized by the government and various sectors for a long time, and various systems have been established to ensure the implementation of sorting. In addition, people are becoming more aware of environmental protection and are making beautiful handicrafts out of garbage. However, little research and attention has been paid to waste segregation in areas with multicultural backgrounds. Some scholars believe that there is a positive relationship between values and lifestyles and ecological behavior. DeYoung says that simple and moderate lifestyles are positively associated with glass and paper recycling. Livers proved that people with religious values and conservative lifestyles like to contribute positively to the improvement of society. This article focuses on the residential neighborhood of University Street in Chonnam University. The residential area is characterized by single apartments, international students, and art studios, and the problem of garbage sorting has not been improved in the neighborhood, and illegal dumping is often found. As people with different habits and diverse backgrounds live in the same area, it is difficult to separate garbage, and it would be more beneficial to develop an area-specific garbage separation program. Therefore, this thesis utilizes the service design methodology to solve the problem.in the discovery stage, field visits are made to investigate the publicity of sorting and recycling, overseas and AI examples are grasped, and user surveys are conducted. In the definition stage, we organize the results of user surveys and in-depth interviews and analyze the problem of garbage sorting through Personas. In the development stage, design insights were drawn from the existing problems and needs. In the final Delivery stage, design value suggestions are made. It is hoped that the program of this thesis can improve the local garbage sorting problem.

Throughout the eastern deciduous forests of North America, a lack of disturbance coupled with advancing ecological succession in many regions has led to forests dominated by even-aged sawtimber with very little in the early successional stage. Monitoring of response of these target species to early successional communities created through Working Lands for Wildlife and Regional Conservation Partnership Programs have been completed. ARU-based regional monitoring protocol was used to assess whip-poor-will occupancy across various landscapes contexts, silvicultural treatments, and forest types in the Appalachian Mountain and New England regions. Researchers conducted milkweed, monarch egg, and larvae surveys simultaneously with the pollinator surveys. Preliminary results support that increasing milkweed and nectar-rich plants within alder and upland early successional communities will provide valuable resources for the monarchs and other pollinators in the northern Great Lakes.--

Sentinel wetlands at Cuyahoga Valley National Park (NP) comprise a set of twenty important management areas and reference sites. These wetlands are monitored more closely than other wetlands in the wetlands monitoring program and are the focus of the volunteer monitoring program for water levels. We used the Ohio Rapid Assessment Method (ORAM) to evaluate habitat in the sentinel wetlands. A total of 37 long-term sample plots have been established within these wetlands to monitor biological condition over time using vegetation as an indicator. Vegetation is intensively surveyed using the Vegetation Index of Biotic Integrity (VIBI), where all plant species within the plot are identified to the lowest taxonomic level possible (genus or species). Sample plots were surveyed twice from 2008 to 2018 and the vegetation data were evaluated using five metrics: VIBI, Floristic Quality Assessment Index (FQAI), percent sensitive plant species, percent invasive graminoids, and species richness. These metrics are discussed for each location. This report also highlights relevant land use histories, common native plant species, and invasive species of concern at each wetland. This is the first report in a two-part series, designed to summarize the results from intensive vegetation surveys completed at sentinel wetlands in 2008–2018. Boston Mills, Virginia Kendall Lake, Stumpy Basin, Columbia, and Beaver Marsh are all in excellent condition at one or more plots. They have unique habitats with some specialized plant species. Fawn Pond is in good condition at most plots and scores very high in comparison to other wetlands within the riverine mainstem hydrogeomorphic class. Metric scores across mitigation wetlands were low. Two of the three wetlands (Brookside and Rockside) are not meeting the benchmarks originally established by the United States Army Corps of Engineers and Ohio Environmental Protection Agency. Krejci is still a young mitigation site and success will be determined over time. Park-supported invasive species control efforts will be crucial for long-term success of these sites and future mitigation/restoration projects. The wetlands monitored because of proposed ecological restoration projects (Pleasant Valley, Stanford, and Fawn Pond) have extensive invasive plant communities. These restoration sites should be re-evaluated for their feasibility and potential success and given an order of prioritization relative to the newer list of restoration sites. Cuyahoga Valley NP has added many new areas to their list of potential wetland restoration sites after these areas were selected, and there may be better opportunities available based on restoration objectives. Restoration goals should be based on the park's desired future conditions, and mitigation goals of outside partners may not always be in line with those. The multiple VIBI plots dispersed throughout the large wetlands at Cuyahoga Valley NP detected and illuminated spatial patterns in condition. Many individual wetlands had a wide range of VIBI scores within their boundaries, sometimes reflecting localized disturbances, past modifications, and management actions. Most often, these large fluctuations in condition were linked to local invasive plant infestations. These infestations appear to be the most obvious and widespread threat to wetland ecosystems within the park, but also the most controllable threat. Some sensitive species are still present in some of the lowest scoring plots, which indicates that invasive plant species control efforts may pay off immediately with a resurgence of native communities. Invasive plant control at rare habitat sites would have large payoffs over time by protecting some of the park's most unique wetlands. Reference wetlands would also be good demonstration sites for park managers to try to maintain exemplary conditions through active management. Through this work, park managers can evaluate the feasibility, effectiveness, and scalability of management practices required to maintain wetland condition.

Due to the multiple and extended openings of the Bonnet Carré Spillway in 2019, the University of Southern Mississippi (USM) was tasked by the Mississippi Department of Marine Resources to conduct ecological sampling in the Mississippi Sound and adjacent waters. in an effort to better understand the impacts of the extensive freshwater diversion of Bonnet Carré Spillway operations on Mississippi's coastal and marine resources. The period of performance for this project was June 1, 2019, to August 31, 2019. This technical report summarizes the three months of weekly surveys and analyses, over June - August 2019, conducted by the University of Southern Mississippi's research team.

St. Croix is home to a variety of threatened and endangered (T&E) species that are at risk for predation by the invasive red-tailed boa (Boa constrictor), such as the St. Croix ground lizard (Amevia polyps), the ground-nesting least tern (Sterna antillarum), and the hawksbill sea turtle (Eretmochelys imbricata). Genetic analysis determined the original red-tailed boa population on St. Croix sourced from a single female released by a pet owner and its range expands every year. Presently, the main population of red-tailed boa is established on the west end of St. Croix and extends as far east as Salt River. One individual was found in Salt River Marina and additional sightings have occurred in Salt River Bay National Historical Park and Ecological Preserve (SARI) more recently. This inventory aims to search for red-tailed boas in two focal areas that park staff are actively restoring. The park will use information from this inventory to develop a boa removal program and protect sensitive native species like the ground-nesting least tern, the St. Croix ground lizard and the hawksbill sea turtle nests and increase the success of restoration. Snakes are cryptic species, often occurring in low density, and utilize complex habitat patterns. To increase the likelihood of detecting red-tailed boa, the Maryland/Delaware/D.C. Wildlife Services detector dog handling team partnered with the USDA-APHIS National Detector Dog Training Center to train and develop detector dogs to assist in determining the presence/absence of red-tailed boa for this project. Canines were trained to locate red-tailed boa and indicate its presence to the handler via barking three times near the identified target. Two dog detector teams traveled to Salt River Bay National Park (SARI) in St. Croix to conduct surveys for red-tailed boa in habitats likely to contain red-tailed boa in June 2023. Habitat varied throughout the surveys. Close to the bay, mangrove forests dominated and, as elevation increased, transects took place in almost exclusively dry tropical shrub forest. Each transect was surveyed by one dog team. The canine teams had no red-tailed boa detections within SARI. Canines showed proficiency at surveying for red-tailed boa populations in SARI. Given the proximity of confirmed detections to SARI, it is likely red-tailed boa will be in the park in the future, if they are not already. Additional surveys, whether by humans, canines, or both, are recommended in areas of the park that have not been previously surveyed.
