Acclimatisation affects synchrony in space use and the frequentation of multiple colonies in translocated Griffon Vultures (Gyps fulvus)

Jacopo Cerri, Davide De Rosa, Mauro Aresu, et al.

Published: 2024-10-16
Subjects: Behavior and Ethology, Zoology

Translocations are fundamental for the conservation of large raptors, including Old-World vultures. Different release methods are usually assessed by comparing the movement patterns and survival of released individuals. However, these approaches fail to capture important aspects related to the gregarious behaviour of many vulture species. We compared the effect of long (15 months, n = 7) and [...]

Reassessing a Holocene extinction: multiple lines of evidence do not support the historical presence and recent extirpation of a protected anole on the island of Anguilla

Subjects: Biodiversity, Genomics, Integrative Biology, Other Ecology and Evolutionary Biology, Zoology

Accurate assessment of historical species ranges is important for conservation science and management. Inaccurate historical species ranges can lead to incorrect assumptions about local extinctions, population trends, and potential sites for reintroductions. Yet, historical knowledge is often lacking for many species. Here, we examine the case of the bearded anole, Anolis pogus, which has long [...]

Demographic expansion and panmixia in a St. Martin endemic, Anolis pogus, coincides with the decline of a competitor

Subjects: Biodiversity, Ecology and Evolutionary Biology, Evolution, Genomics, Population Biology, Zoology

Understanding patterns of differentiation at microgeographic scales can enhance our understanding of evolutionary dynamics and lead to the development of effective conservation strategies. In particular, high levels of landscape heterogeneity can strongly influence species abundances, genetic structure, and demographic trends. The bearded anole, Anolis pogus, is endemic to the topographically [...]

Molecular plasticity contributes to thermal resilience in two coastal fish species

Breana Marie Riordan, Ludovic Dutoit, Tania King, et al.

Published: 2024-09-03
Subjects: Life Sciences, Zoology

Understanding species capacities to adjust to shifting thermal environments is crucial amidst current climate-mediated ocean warming. Fish populations displaying high thermal plasticity can undergo molecular, metabolic, and mitochondrial modifications in response to heat stress. Under the context of heat stress, such acclimation provides a means to maintain normal biological functions through [...]

Sunlight and diel behaviors promote coexistence of frogs through temporal acoustic partitioning

Bryan Hernandez Juarez, Yuren Sun, Trevor Hebert, et al.

Published: 2024-08-12
Subjects: Behavior and Ethology, Longitudinal Data Analysis and Time Series, Statistical Methodology, Statistical Models, Terrestrial and Aquatic Ecology, Zoology

Understanding how species coexist is one of the main goals in ecology. While many have documented how species coexist in nature, there is much interspecific and spatial heterogeneity in which resources are partitioned and in the contributing environmental factors. Overall, we lack a general understanding of how stable coexistence is maintained for particular groups of organisms. Thus, we studied [...]

Subjects: Applied Statistics, Biodiversity, Biostatistics, Ecology and Evolutionary Biology, Longitudinal Data Analysis and Time Series, Natural Resources and Conservation, Population Biology, Statistical Methodology, Statistical Models, Survival Analysis, Terrestrial and Aquatic Ecology, Zoology

Expanding populations of mesopredators threaten biodiversity and human health in many ecosystems across the world. Lethal control through harvest is commonly implemented as a mitigation measure, yet the effects of harvest and its interaction with environmental conditions on mesopredator population dynamics have rarely been assessed quantitatively due to data constraints. Recent advances [...]

Strong small-scale differentiation but no cryptic species within the two isopod species Asellus aquaticus and Proasellus coxalis in a restored urban river system (Emscher, Germany)

Martina Weiss, Armin W. Lorenz, Christian K. Feld, et al.

Published: 2024-07-04
Subjects: Biodiversity, Ecology and Evolutionary Biology, Genetics and Genomics, Life Sciences, Zoology

Worldwide, humans have strongly altered river networks. Key changes resulted in modified hydromorphology, poor habitat quality and availability, migration barriers, and pollution. Restoration measures aim at mitigating anthropogenic stressors and to restore connectivity, but the biological success of the measures is not guaranteed. Analyzing genetic diversity and population structure of target [...]

Light Pollution at Sea: Implications and Potential Hazards of Human Activity for Offshore Bird and Bat Movements in the Greater North Sea

Human activity in the North Sea is intensifying, as emerging uses, such as offshore wind farms (OWFs) and liquid natural gas (LNG) terminals, are added to fishing, freight shipping and fossil fuel production as traditional forms of resource exploitation. The volume and scale of these additional installations are projected to increase substantially in the coming decades, which amplifies the need [...]

Nest-site selection and nest predation in a tropical passerine in relation to food, friends and foes

Arne Van Eerden, Jan Komdeur, David S Richardson, et al.

Published: 2024-03-04
Subjects: Behavior and Ethology, Ornithology, Zoology

Nest-site selection is an important determinant of avian reproductive success, mainly through its effect on predation risk. However, how environmental and social factors affect nest-site selection and predation risk remains less well understood. Optimal nest positioning may depend on the balance of many distinct factors such as nest predation, food availability, extra-pair mating opportunities, [...]

Global exposure risk of frogs to increasing environmental dryness

Nicholas C. Wu, Rafael P Bovo, Urtzi Enriquez-Urzelai, et al.

Published: 2024-02-08
Subjects: Comparative and Evolutionary Physiology, Ecology and Evolutionary Biology, Zoology

Compared with the risks associated with climate warming and extremes, the risks of climate-induced drying to animal species remain understudied. This is particularly true for water-sensitive groups, such as anurans (frogs and toads), whose long-term survival must be considered in the context of both environmental changes and species sensitivity. Here, we mapped global areas where anurans will [...]

Puma space use and dispersal in tropical biodiversity hotspots: bridging a gap to connect individuals to populations
