Global patterns of vulnerability to wildlife exploitation in tropical birds and mammals
Published: 2026-05-01
Subjects: Ecology and Evolutionary Biology
Wildlife exploitation is one of the most pervasive anthropogenic pressures in tropical ecosystems and a major driver of vertebrate population declines, yet global assessments of species vulnerability to hunting remain spatially imprecise and methodologically inconsistent. We combine exposure to hunting with species-specific sensitivity and adaptive capacity to deliver a spatially explicit [...]
Resprouting responses to light environment and cutting season differ across resprouting stages and leaf habit in a heavy-snow Japanese beech forest.
Published: 2026-05-01
Subjects: Life Sciences
Resprouting is a key mechanism of recovery after aboveground damage and strongly influences forest regeneration and dynamics. This is also true in heavy-snow Japanese beech forests, where canopy-gap formation and snow pressure damage woody species. Understanding how light environment and disturbance season shape resprouting is therefore essential for interpreting life-history strategies and [...]
Sex differential effects of developmental heat stress on life-history and reproductive traits
Published: 2026-05-01
Subjects: Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Evolution, Life Sciences
Global warming has led to increased mean global temperatures with projections suggesting continued warming throughout this century, posing an escalating threat to biological systems worldwide. Ectotherms are most vulnerable to this change as heat stress conditions can have severe implications on their development, mating interactions, and fitness. However, the sex-specific effects of [...]
Synthesis of Anthropogenic Impacts on Birds - Systematic Map and Bibliometric Analysis of Meta-Analyses
Published: 2026-05-01
Subjects: Life Sciences
Anthropogenic environmental change is a major driver of global bird declines, affecting species across continents, ecosystems, and life-history strategies. As such, it has drawn much attention in both primary research studies and meta-analyses. Because meta-analyses influence scientific consensus and conservation policy, it is essential to evaluate the representativeness and transparency of this [...]
When Policy Shapes Selection: Anticipating Evolutionary Feedbacks in Conservation
Published: 2026-05-01
Subjects: Physical Sciences and Mathematics
Applied ecology and conservation increasingly operate in systems where ecological and evolutionary processes are tightly coupled and can unfold on management-relevant timescales, yet most policy still treats populations as evolutionarily static. As a result, interventions often generate unintended outcomes, from resistance evolution and harvest-induced trait shifts to hidden losses of adaptive [...]
The significance gap: statistical significance rates decrease from primary literature to effects used in ecological meta-analyses

IUCN Red List of Ecosystems, Mangroves of the Warm Temperate Northwest Pacific
Published: 2026-05-01
Subjects: Life Sciences
Mangroves of the Warm Temperate Northwest Pacific is a regional ecosystem subgroup (level 4 unit of the IUCN Global Ecosystem Typology). It includes intertidal forests and shrublands of the marine ecoregions of the East China Sea, that extend across China, Taiwan and South Korea. The Warm Temperate Northwest Pacific mangrove province mapped extent in 2023 was 6.83 km2, representing 0.0038% of the [...]
Extending {spatsoc} to measure intragroup social dynamics
Published: 2026-05-01
Subjects: Animal Studies, Behavior and Ethology, Ecology and Evolutionary Biology, Software Engineering
Beyond proximity-based social networks and home range overlap, animal telemetry data can also be used to measure intragroup social dynamics including individual position within groups, individual and group level movement directions, leadership patterns and lagged follower behaviours. We used a scoping review of literature across domains, including behavioural ecology, collective movement, and [...]
Achieving Target 1 through effective spatial planning underpins the long-term success of the Convention on Biological Diversity’s Global Biodiversity Framework
Published: 2026-05-01
Subjects: Life Sciences
The first target of the Kunming–Montreal Global Biodiversity Framework (KM-GBF) mandates signatory nations of the Convention on Biological Diversity (CBD) to address biodiversity loss across all regions within their national jurisdictions by 2030 by implementing Participatory, Integrated, and Biodiversity-Inclusive Spatial Planning (BISP). Delivering Target 1 through coordinated, inclusive [...]
Lead and slant on the geometry of coiling in gastropods
Published: 2026-05-01
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences, Other Ecology and Evolutionary Biology, Physical Sciences and Mathematics
Molluscan shells have been studied with various geometric models. Here I show that lead angle, the defining slope of a conical helix, emerges as a more useful parameter in morphometric analyses and (adaptationist) interpretation of covariation in coiling parameters. The widely used apical semiangle becomes redundant and uninformative, a passive consequence of taxon-specific lead angles and [...]
A Substrate-Driven Plasticity Hypothesis for the Monterey Ensatina Salamander (Ensatina eschscholtzii)
Published: 2026-04-30
Subjects: Behavior and Ethology
Abstract.—Phenotypic plasticity allows many amphibians, including several salamander species, to adjust skin luminance in response to background brightness. In habitats with heterogeneous substrates in color and brightness, such plasticity may generate substantial individual variation within a population. In a population of the terrestrial salamander Ensatina eschscholtzii, a recent study [...]
Learning, motivation, and social interaction in modern dolphin training
Published: 2026-04-30
Subjects: Life Sciences, Social and Behavioral Sciences
Dolphin training is widely practiced in zoological facilities for performance, husbandry, research, and daily management, yet many of its practical principles remain insufficiently formalized in the scientific literature. This Perspective aims to provide a citable academic framework for modern dolphin training by synthesizing trainer-based practical knowledge within established concepts from [...]
aae.pop: Flexible population dynamics simulations in R
Published: 2026-04-30
Subjects: Applied Mathematics, Ecology and Evolutionary Biology
1. Matrix population models (MPMs) are commonly used to address fundamental ecological questions and guide real-world management decisions. Several open-source software packages support the fundamental analysis of MPMs, but few options exist to simulate from models that include realistic ecological complexity, such as density dependence, covariate effects, and interspecific interactions. 2. The [...]
Spatial Behavior and Long-Term Decline of Radiocesium in Green Pheasants (Phasianus versicolor) in Fukushima: A Left-Censored Regression Approach
Published: 2026-04-30
Subjects: Life Sciences
Long-term monitoring of radiocesium (137Cs) in wildlife is important for assessing environmental recovery after the Fukushima Daiichi Nuclear Power Plant accident. We integrated GPS telemetry data with muscle 137Cs concentrations in green pheasants (Phasianus versicolor) to evaluate whether observed declines in radiocesium are consistent with reduced local environmental availability. Winter [...]
Reindeer habitat selection and movement changes with cumulative impacts from mining and wind power development
Published: 2026-04-30
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Forest Management, Life Sciences, Terrestrial and Aquatic Ecology, Zoology
Industrial expansion often occurs in landscapes already affected by multiple disturbances, leading to cumulative impacts on biodiversity and local communities. With the societal pressure for an rapid ‘green transition’, land-use changes intensifies, yet most impact assessments remain local and project-based, disregarding cumulative impacts. We conceptualized and disentangled key dimensions of [...]
