Distribution et noyaux périphériques de la Pie-grièche méridionale Lanius meridionalis en France : apport d’un modèle de distribution d’espèces
Published: 2025-09-05
Subjects: Life Sciences
Cette étude analyse les facteurs environnementaux influençant la distribution de la Pie-grièche méridionale Lanius meridionalis en France à partir d’observations 2020–2023 collectées en période de reproduction. La probabilité de présence est principalement expliquée par des variables climatiques, topographiques et d’occupation du sol. Elle augmente avec la température moyenne du trimestre le plus [...]
Systematic review of heatwave experiments on plant health and survival
Published: 2025-09-04
Subjects: Life Sciences
Background: Heatwaves, which are becoming more intense and more frequent due to global warming, are a major threat to the stability of plant populations and ecosystems. Safeguarding ecosystem function requires a clear understanding of vulnerability to these extreme events. Yet vulnerability cannot be reliably inferred from experiments that manipulate only mean temperatures or from standard [...]
Interaction Matrices as Unifying Tools for Navigating Ecological Complexity
Published: 2025-09-04
Subjects: Ecology and Evolutionary Biology, Life Sciences
Interaction matrices summarise pairwise species impacts within ecological communities into an analytically tractable format and have been central to advancing our understanding of ecosystem dynamics. However, despite their ubiquity, they have faced constant, recurring, criticism for oversimplifying ecological complexity. While suggested extensions address specific shortcomings, they often come [...]
Contribution to the knowledge of the distribution of bats (Chiroptera) in Algeria
Published: 2025-09-04
Subjects: Biodiversity, Biology, Life Sciences, Zoology
Algeria is the largest country in Africa and for the most part has not yet been surveyed for bat species. To contribute to the knowledge of the distribution of Algerian bat fauna, between 2010 and 2025 we surveyed 69 sites from across the country, mostly roost sites but also using mist nets. We found 19 species from six families, out of a total of 27 species from seven families currently [...]
Potential for academic institutions to support international biodiversity commitments
Published: 2025-09-04
Subjects: Environmental Policy, Environmental Studies
The implementation of the Kunming-Montreal Global Biodiversity Framework (KMGBF) of the Convention on Biological Diversity (CBD) emphasises a “whole of government and whole of society” approach to achieving ambitious biodiversity conservation Goals and Targets. The CBD invites academic and research institutions to support these efforts and has recently launched regional/sub-regional Technical and [...]
Advancing single species abundance models by leveraging multi-species data to reveal lake-specific patterns for fisheries predictions
Published: 2025-09-03
Subjects: Environmental Monitoring, Sustainability, Water Resource Management
Predicting species abundance is critical for understanding ecological dynamics and guiding conservation and management strategies. Traditional species abundance models (SAMs) rely on environmental variables and the presence or absence of key species, but often overlook community context and unmeasured environmental variation. Community composition can serve as a proxy for both unobserved [...]
Genetic Structure and Population Differentiation of Chrysanthemum zawadzkii in Its Isolated European Range
Published: 2025-09-03
Subjects: Population Biology
This study investigated the genetic structure and diversity of Zawadzki's chrysanthemum (Chrysanthemum zawadzkii), a relict and endemic species with an isolated population in the Pieniny Mountains, Central Europe. The primary objective was to determine whether this population is genetically homogenous or consists of distinct subpopulations. To achieve this, plant material was collected from 13 [...]
Relational Thinking for Landscape Management and Conservation: can we really embrace a human/nature continuity?
Published: 2025-09-01
Subjects: Biodiversity, Environmental Studies
It is increasingly recognized that the conservation of natural and degraded landscapes requires rethinking our relationships with nature by considering social-ecological complexity. Currently, managers are faced with a wealth of knowledge in landscape ecology, restoration ecology and related fields, that are all mobilized to solve management problems. However, many conceptual propositions fall [...]
What time is it? Interactions between trees and fossils
Published: 2025-09-01
Subjects: Life Sciences
Molecular sequence data is not in itself informative about absolute evolutionary timescales. Fossils are therefore often analysed alongside molecular data in order to generate time-scaled reconstructions of the tree-of-life. Here, I analyse interactions between fossils and molecular based reconstructions of the tree-of-life, and explore the implications of these interactions for time-scaling the [...]

Revealing the unknown world of the endangered Lear's macaw using GPS-tracking data: identification of critical habitats for conservation
Published: 2025-08-31
Subjects: Biology, Ecology and Evolutionary Biology
Understanding space use and home range is essential for the conservation planning of threatened species as it helps to assess the suitability, extent, and placement of conservation areas that are imperative for species survival and protection. The Endangered Lear’s macaw (Anodorhynchus leari), a highly mobile frugivore, feeding specialist and endemic to Brazil’s Caatinga dry forest, faces ongoing [...]
BPGA: an interactive Shiny application for basic population genetic analysis of genotype data
Published: 2025-08-31
Subjects: Bioinformatics, Education, Genetics and Genomics, Higher Education, Life Sciences
Background: Population structure and ancestry inference are routine in human genetics, yet remain inconvenient for non-experts because canonical tools (PLINK, GCTA, ADMIXTURE) require command-line expertise and careful data management. Results: BPGA (Basic Population Genetic Analysis) is an open‑source R/Shiny application that provides an interactive workflow for educational and [...]
Persefone.jl: Modelling Biodiversity in Dynamic Agricultural Landscapes
Published: 2025-08-31
Subjects: Agriculture, Behavior and Ethology, Biodiversity, Population Biology
Agricultural landscapes are highly dynamic, constantly changing in space and time due to the effects of farm management and environmental factors. To forecast the effects of changes in agricultural systems on biodiversity, we need to understand these landscape dynamics and how they impact different species. Here, we present Persefone.jl, an open-source process-based model of agricultural [...]
Mapping multiple dimensions of forest diversity using spaceborne spectroscopy
Published: 2025-08-31
Subjects: Biodiversity, Life Sciences
Observing biodiversity across space and time is essential for advancing and verifying conservation efforts toward global biodiversity and sustainability goals. Spaceborne imaging spectroscopy has emerged as a revolutionary tool for quantifying and tracking forest diversity, yet its application at large spatial scales remains a central challenge. We develop a framework to map multiple dimensions [...]
An evolving view of character macroevolution
Published: 2025-08-31
Subjects: Life Sciences
Phenotypes serve as the interface between organisms and their environments and are thus pivotal for comprehensive biological understanding. However, comparative analyses of species’ phenotypes must account for the non-independence of characters imposed by the branching pattern of macroevolution. Methods to account for this phylogenetic non-independence have historically been conceived of as their [...]
