National-scale estimates of mammal species abundance in Italy for the Habitat Directive reporting
Published: 2025-08-08
Subjects: Ecology and Evolutionary Biology, Population Biology
This report describes the methodological frameworks developed in collaboration with ATIt ETS (https://www.mammiferi.org) to estimate the abundance of mammal populations at the scale of Italy for the species listed under Annexes II, IV, and V of the Habitats Directive. For each species, the estimation methodology was defined based on the availability and quality of data supplied by the individual [...]
Improving the temporal transferability of species distribution models under climate change by incorporating historical species-climate relationship
Published: 2025-08-04
Subjects: Ecology and Evolutionary Biology, Life Sciences
Understanding how species will respond to climate change is one of the current key challenges in ecology and nature conservation. The tempo-spatial variations of climate makes it more challenging to predict species responses to climate change across their entire ranges. Species distribution models have been widely used for identifying how species distributions respond to climatic drivers. Despite [...]
Trait shifts during range expansions: A meta-analysis
Published: 2025-08-03
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Populations undergoing range expansions often undergo phenotypic shifts at the leading edge. Understanding how traits change during range expansions could provide insight into predicting invasive species dynamics and responses to climate change. Theory predicts that edge populations should increase in dispersal capability and shift towards reproductive traits that maximize fecundity over [...]
An Evolutionary Hypothesis on the Persistence of Non-Coding DNA in Complex Genomes: The Passive Selfish DNA Model
Published: 2025-08-02
Subjects: Ecology and Evolutionary Biology, Life Sciences
Non-coding DNA constitutes the vast majority of eukaryotic genomes, yet its evolutionary role remains largely unresolved. This manuscript proposes a theoretical model in which non-coding DNA persists not due to functional utility, but as "passive selfish DNA"—elements that replicate by coexisting with coding sequences in vital genomes. Drawing analogies with endogenous retroviruses and vertically [...]
TADA! Simple guidelines to improve code sharing
Published: 2025-08-02
Subjects: Ecology and Evolutionary Biology, Life Sciences
Code sharing is important for transparency and facilitates computational reproducibility of published research. However, even as the number of journals that encourage or mandate code sharing continues to increase, the prevalence of open code remains low. Furthermore, even when shared, code is often non-functional, which hinders computational reproducibility. One reason for low levels of code [...]
Exploring the Integration of Traditional Ecological Knowledge with Artificial Intelligence to Mitigate Human-Wildlife Conflict in Kerala, India
Published: 2025-08-01
Subjects: Animal Sciences, Behavior and Ethology, Biodiversity, Biology, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology, Zoology
Increasing human-wildlife conflict (HWC) in forest-fringe landscapes necessitates innovative and culturally acceptable mitigation strategies. This note proposes integrating Traditional Ecological Knowledge (TEK) with Artificial Intelligence (AI) to mitigate HWC in Kerala. The proposition aims to translate African rural traditional knowledge of using alarm calls of Guinea fowls (Numida meleagris) [...]
Causal models as a scientific framework for next-generation ecosystem and climate-linked stock assessments
Published: 2025-07-31
Subjects: Biostatistics, Ecology and Evolutionary Biology, Environmental Sciences, Marine Biology, Natural Resources and Conservation, Population Biology, Statistical Methodology, Statistical Models, Terrestrial and Aquatic Ecology
Rapid changes in marine ecosystems highlight the need to account for time-varying productivity in stock assessment models used to support fisheries management. Common approaches incorporate annual variation or regress processes like recruitment, natural mortality, or growth on environmental covariates. While the latter represents a step towards biological realism, it often fails accounting for [...]
What's really happening on the Barro Colorado Island 50 ha forest plot?
Published: 2025-07-28
Subjects: Biodiversity, Ecology and Evolutionary Biology
1. Over the decades, Barro Colorado Island (BCI) has incubated major conceptual and empirical advances in ecology. For example, the theoretical zero-sum multinomial (ZSM), log series, and Poisson log normal (PLN) models have been used to describe abundance distributions and quantify diversity in the BCI 50 ha forest plot. 2. A new model called the compound exponential-geometric series (CEGS) [...]

DeepResearch_Eco: A Recursive AgenticWorkflow for Complex Scientific Question Answering in Ecology
Published: 2025-07-27
Subjects: Computer Sciences, Ecology and Evolutionary Biology
We introduce DeepResearch_Eco, a novel agentic LLM-based system for automated scientific synthesis that supports recursive, depth- and breadth-controlled exploration of original research questions—enhancing search diversity and nuance in the retrieval of relevant scientific literature. Unlike conventional retrieval-augmented generation pipelines, DeepResearch enables user-controllable synthesis [...]
The Marsupial Database: A comprehensive dataset on the ecology and life history of American and Australasian marsupials
Published: 2025-07-25
Subjects: Ecology and Evolutionary Biology, Life Sciences
Marsupials are an important but typically neglected group of mammals that have been overlooked in many comparative analyses of vertebrate ecology and life-history evolution. In order to address this knowledge bias, we have developed The Marsupial Database. The Marsupial Database contains traits for a phylogenetically diverse set of 414 extant and recently extinct (last 200 years) species from all [...]
Physical and Migration Metrics of White Storks (Ciconia ciconia) and the influence that landfills play in their variation
Published: 2025-07-25
Subjects: Comparative and Evolutionary Physiology, Ecology and Evolutionary Biology, Life Sciences, Ornithology, Zoology
1. White storks (Ciconia Ciconia) are a traditionally fully migratory species and their numbers in western Europe were decimated in the last century. Their numbers have since boomed and they have altered their migratory strategy to have become a partially migratory species. This change has been ascribed in large part to anthropogenic food subsidies, particularly in the form of landfill sites. 2. [...]
Assessing direct effects of insect change on insectivore populations in the United Kingdom
Published: 2025-07-25
Subjects: Biodiversity, Ecology and Evolutionary Biology, Population Biology
1. Declines in insect abundance are a cause for concern, with potential downstream impacts on the function of ecosystems. Insects are key food resources for insectivorous vertebrates, with evidence that declines in these species could be driven by changing insect abundance. 2. Quantifying the direct effect of insect abundance on vertebrate population dynamics is challenging especially at large [...]
Recruitment bottlenecks and reinforcing environmental degradation drive marsh collapse
Published: 2025-07-24
Subjects: Ecology and Evolutionary Biology
Ecosystem collapse is often attributed to the absence of stress-tolerant species, yet many climate-stressed systems fail even when these species remain regionally present. This raises a critical, unresolved question: does collapse result from species pool depletion, or from failed recruitment? We addressed this by combining vegetation surveys and a three-year transplant experiment in sea level [...]
Location–scale models in ecology and evolution: heteroscedasticity in continuous, count and proportion data
Published: 2025-07-22
Subjects: Ecology and Evolutionary Biology
Ecological data seldom meet the assumption of constant variance. Yet patterns of heteroscedasticity often reflect biologically meaningful variation, such as differences in plasticity or variable responses to environmental stresses. However, most studies model only the mean, treating variance as statistical noise. Here, we describe location–scale regression modeling, which estimates mean [...]
