Resumen

Introduction: Poor waste management led to mosquito breeding grounds. Previous research found that construction sites are the mosquito breeding area thus it’s important to understand how construction sites affect mosquito breeding. Methods: This study utilized a prospective study to determine the characteristic of breeding preference in residential construction sites. On-field breeding preference survey was conduct in the selected project site in 12 weeks (1st October 2021 until 31st December 2021).

Resumen

The breeding densities of migrant birds are subject to a wide range of influences that may cause their variation, within a site from one year to another, within years but among habitats and sites from one location to another, and also among species with different migration strategies in terms of travel distances and wintering habitats. First measuring, and then understanding, this variation and its drivers is a substantial challenge for breeding bird monitors and population ecologists. Variation in breeding bird densities in Grand Teton National Park have been monitored since the early 1990's,

The Whooper Swan Cygnus cygnus has shown a remarkable breeding population increase and range expansion in Northern Europe during recent decades. Here, I summarize the temporal and spatial pattern of the expansion in Oslo and Akershus counties in southeastern Norway, and assess current and potential future competition with Mute Swans Cygnus olor. The first breeding was reported in 1999, and in 2003 breeding was reported at a second site. From 2006 the number of breeding sites increased rapidly, and the species has now been reported breeding from a total of 20 sites. However, at least seven site

Resumen

The food resource hypothesis of breeding habitat selection in beach-nesting birds suggests that birds breed at sites with more prey to meet the increased energetic requirements associated with breeding. We compare prey resources using pitfall traps and core samples at breeding sites and absence sites of the eastern population of hooded plover, Thinornis rubricollis rubricollis, which, in this part of its range, is a threatened obligate beach bird. Breeding sites had higher abundances, equivalent species richness, and different assemblages of invertebrate prey compared with absence sites. Assem

Resumen

SummaryAn innovative approach to tree breeding called ‘breeding without breeding’ (BWB) is presented. The method, as applied on the material in hand, allows the capture of 75–85% of the genetic response to selection attained through conventional programmes without the need to do any controlled pollination and simplified or possibly no experimental field testing: both considered to be the most resource-demanding activities in breeding programmes. BWB combines the use of genotypic or phenotypic pre-selection of superior individuals, informative DNA markers for fingerprinting and pedigree reconst

Resumen

Waterbirds across Australia are in significant decline. Aerial surveys have been used to estimate waterbird abundance, but their efficacy for estimating breeding is unclear. I collated records of ibis breeding to complement aerial survey data. These data from across Victoria between 1980–1981 and 2023–2024 are from birdwatchers, BirdLife Australia’s Birdata, eBird and the Australian Waterbird Surveys databases and from the literature. Ibis were recorded breeding at 79 sites across Victoria, including 53 sites where the only ibis species to breed was Australian White Ibis Threskiornis moluccus,

Resumen

Red-throated Loons Gavia stellata have disappeared from breeding sites regularly used in the mid-1990s, but it is not clear if this reflects a population decline or movements to other sites. Therefore, we searched for potential breeding sites, including sites with old records, in three regions in southern Sweden, where it was possible to repeat surveys conducted in the past. A pattern of abandonment and return to breeding sites was verified; around 30% of the sites were abandoned over a 10-year period, but the loss was largely compensated by establishment at new sites or return to sites used i

A colonization experiment was used to investigate landscape use of a commercially managed wet forest in southern Tasmania by the ground-dwelling frog, Crinia signifera. Replicated artificial ponds were placed at increasing distances (20, 100, 250 and 500 m) from nine permanent breeding sites to investigate the effect of pond isolation on colonization. Four of these permanent breeding sites were surrounded by coupes that had been logged within the previous five years and five permanent breeding sites were surrounded by unlogged forest to investigate the effect of recent logging on colonization.

Resumen

Breeding site characteristics of Thick-billed Murres, Uria lomvia, differed significantly between Cape Hay, Bylot Island, and Coburg Island, N.W.T., Canada. Logistic regression analysis showed that at both colonies site characteristics had significant effects on breeding success. At Coburg Island the slope and width of the ledge were the most important factors, whereas at Cape Hay the number of walls and neighbours, and to a lesser extent the width of the ledge, best explained the variation observed in breeding success. Egg and chick mortality factors differed at each colony. At Coburg Island

We studied the use of nest-sites by Griffon Vultures (Gyps fulvus) and the breeding success in these sites during 1998–2002 in Gamla Nature Reserve (Israel). Nest-sites in which a breeding attempt succeeded in fledging a young, were more likely to be occupied by nesting vultures in the following breeding season, than nest-sites that experienced a failure. This suggests that Griffon Vultures in Gamla used a Win–Stay/Lose–Shift strategy regarding nest-site fidelity.

The main conclusion is as follows: in the clustered distributions, the prevalence is lower, but the eradication is more difficult to be achieved, as compared to homogeneous distributions.

Resumen

SummaryLear’s Macaw Anodorhynchus leari is currently listed as “Endangered” by IUCN. Although it only breeds on cliffs at two protected sites in Bahia State, Brazil, there is no accurate information on population parameters such as the number of breeding pairs and their breeding performance. Between 2009 and 2010, we sought to quantify, for the first time, breeding population size and the main breeding parameters for the species in the two known breeding sites, by quantifying the number of active nests and monitoring 75 breeding attempts. Overall, 80% of the breeding attempts were successful w

Resumen

AbstractRose's mountain toad Capensibufo rosei survives in a few isolated montane populations in the south-western Cape of South Africa. It comprises several cryptic species but it is uncertain whether the lineage on the Cape Peninsula is distinct. We tested the hypothesis that toads from the Peninsula form a single genetic lineage but that different breeding sites are divergent at a population level as a result of limited dispersal abilities. Directed surveys were carried out to locate breeding sites and samples obtained were analysed in a phylogenetic and population genetic framework, using

Resumen

AbstractGenetic improvement of Douglas-fir in New Zealand was initiated in 1955 with large provenance trials established in the late 1950’s. These trials illustrated that material from the coast of Oregon and California grew faster than other provenances tested. Further collections were made to evaluate provenance and familylevel performance from these two areas, and in 1996 additional trials were established at four low-altitude sites across New Zealand. Genotype×environment (GxE) interaction among these sites was found to be important for diameter at breast height (DBH), less important for s

Resumen

I visited 10 breeding sites across the range of Fiordland crested penguins (Eudyptes pachyrhynchus) in 1995. Based on the developmental stage of chicks at each of the sites, breeding begins progressively later in more northern colonies. Fiordland crested penguins had unusually high hatching success on Taumaka I. (Open Bay Islands) in 1995, and I suggest from anecdotal observations made at the nine other sites that 12% of pairs may have raised two chicks in that year. Together, these observations suggest that Fiordland crested penguins had an unusually good breeding season in 1995. The suggesti

Resumen

Protection from the elements, predators and parasitoids, and access to food is critical for insect larvae. Therefore, adult female insects are strongly selected to deposit offspring in safe, nutritious locations. Additionally, larvae may move to new feeding sites as food becomes depleted at the natal site. Maggots of carrion-breeding flies exploit patchy resources and are at risk from predators, desiccation and competition. Natural orifices, body folds, fur and feathers are protective locations that provide ready access to food, but their suitability as ovi- or larviposition sites may vary acc

Resumen

The fitness of female Pacific salmon (Oncorhynchus spp.) with respect to breeding behavior can be partitioned into at least four fitness components: survival to reproduction, competition for breeding sites, success of egg incubation, and suitability of the local environment near breeding sites for early rearing of juveniles. We evaluated the relative influences of habitat features linked to these fitness components with respect to selection of breeding sites by coho salmon (Oncorhynchus kisutch). We also evaluated associations between breeding site selection and additions of large wood, as the

Disease control programs are needed to identify the breeding sites of mosquitoes, which transmit malaria and other diseases, in order to target interventions and identify environmental risk factors. The increasing availability of very-high-resolution drone data provides new opportunities to find and characterize these vector breeding sites. Within this study, drone images from two malaria-endemic regions in Burkina Faso and Côte d’Ivoire were assembled and labeled using open-source tools.
