iDeer: A decision-support tool for managing deer alongside woodland creation
Published: 2026-03-19
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Forest Management, Life Sciences, Terrestrial and Aquatic Ecology
Increasing deer (Cervidae) densities driven by land-use change and climate warming represent a growing challenge to the establishment and management of woodlands across temperate biomes. Targeting deer management is challenging without spatially explicit information on potential impact risks under alternative management scenarios. Here we present the iDeer Tool [...]
The Finite Element method to aid modelling of complex ecological systems
Published: 2026-03-18
Subjects: Ecology and Evolutionary Biology, Life Sciences
Predicting how biodiversity responds to environmental change and management interventions remains a major challenge in ecology. Ecological systems are shaped by the interplay of demographic processes, species interactions, dispersal, and spatial heterogeneity across landscapes. Yet, many existing modelling approaches face a trade-off between spatial and ecological complexity, which limits their [...]
The scent of survival in a warming world: how monoterpenes drive thermal adaptation in thyme
Published: 2026-03-18
Subjects: Comparative and Evolutionary Physiology, Ecology and Evolutionary Biology, Evolution, Life Sciences, Other Ecology and Evolutionary Biology, Other Plant Sciences, Physiology, Plant Biology, Plant Sciences, Population Biology
1 Monoterpenes are key plant secondary metabolites with well known defensive and ecological functions, yet their role in abiotic stress tolerance remains poorly understood. In many Mediterranean plants, monoterpene composition varies markedly within and among species and is associated with climatic gradients, suggesting that these compounds may mediate plant responses to extreme heat. 2 We [...]
Flexibility training does not increase behavioral flexibility of Florida scrub-jays
Published: 2026-03-18
Subjects: Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Life Sciences
Human modifications of environments are expanding, causing global changes that other species must adjust to or suffer from. Behavioral flexibility (hereafter 'flexibility') could be key to coping with rapid change. Behavioral research can contribute to conservation by determining which behaviors can predict the ability to adjust to human modified environments and whether these can be manipulated. [...]
Heterogeneity: Meaning and Measurement, Causes and Consequences
Published: 2026-03-16
Subjects: Ecology and Evolutionary Biology, Life Sciences
Heterogeneity—the variation within and among collectives whose constituent entities interact and integrate into larger, functioning wholes, distinguished fundamentally from diversity as mere variation within non-interacting populations—has emerged as a central organizing principle across ecology and its allied fields. Yet the term remains ambiguously defined, often conflated with diversity [...]
Evaluating population resilience to anticipated stressors using integrated population modeling: a case study of Peregrine Falcons
Published: 2026-03-15
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Life Sciences, Ornithology, Population Biology
Reliable estimates of demographic parameters are fundamental to understanding population dynamics and guiding conservation efforts. Integrated population models (IPMs) provide a powerful framework for jointly analyzing diverse data sources to estimate demographic rates and population trajectories, evaluate resilience to environmental stressors, and project population dynamics info the future. We [...]
Are earthworms really in decline? Representative data and rigorous models are needed to assess large-scale, long-term trends in earthworm populations
Published: 2026-03-15
Subjects: Ecology and Evolutionary Biology
Declines in aboveground invertebrates have been reported widely but similar assessments belowground are rare. A recent quantitative study aimed to address this gap, presenting findings which suggested alarming long-term declines in earthworm abundance in the UK. Estimating temporal trends in abundance from diverse sources of data presents many challenges and there is a need for rigour toward [...]
Assessing the dual utility of nuptial patterning in the rainbow darter (Etheostoma caeruleum)
Published: 2026-03-15
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
In this study, we assessed the possible dual utility of nuptial color patterns in male rainbow darters (Etheostoma caeruleum) in the context of male-male territorial interactions and female mate choice. Using a cohort of wild-caught male E. caeruleum, we conducted simulated territorial contests between pairs of males in the lab. We scored the “winner” and the “loser” of each contest based on [...]
Drivers of roe deer use in fragmented forest landscapes; implications for management in the context of policy driven forest expansion
Published: 2026-03-13
Subjects: Animal Sciences, Behavior and Ethology, Ecology and Evolutionary Biology, Forest Management, Forest Sciences, Life Sciences, Zoology
Forest expansion is a major current land use change across Europe. How this will affect the forest use of the most common European wild ungulate species, roe deer (Capreolus capreolus), and associated forest ecosystem services and disservices is poorly understood. Using a forest-agricultural mosaic landscape in northeast Scotland, we selected forests across a size and connectivity gradient as a [...]
Understanding Conservation Decision-makers’ Preferences for Evidence
Published: 2026-03-11
Subjects: Biodiversity, Ecology and Evolutionary Biology, Environmental Policy, Other Ecology and Evolutionary Biology, Other Economics, Other Social and Behavioral Sciences, Terrestrial and Aquatic Ecology
1. Effective conservation depends on decisions informed by evidence that is both trustworthy and relevant to specific local contexts. However, little is known about which characteristics of evidence conservation decision-makers prioritise when deciding what information to trust. 2. We explored decision-makers’ preferences for different attributes of evidence using a discrete choice experiment in [...]
The lens of the Sonic Holobiont. A perspective on acoustic influence on microbial communities and its application as an additional layer to the holobiont concept.
Published: 2026-03-11
Subjects: Arts and Humanities, Biochemistry, Biophysics, and Structural Biology, Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Microbiology, Other Arts and Humanities, Other Physical Sciences and Mathematics, Physical Sciences and Mathematics
When studying micro and macro biomes in the quest for a more general understanding, we can hardly escape from a holistic perspective. At first, symbiosis was demonstrated to be a ubiquitous phenomenon in living cells, shaping evolutionary patterns across species at very different scales. The “holobiont” concept gains a central role in modern biology. The observation of the complex inter- and [...]
Global latitudinal and bathymetric gradients in body size among cartilaginous fishes (Gnathostomata: Chondrichthyes)
Published: 2026-03-11
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology
Understanding the macroecological rules governing body size variation across environmental gradients has long been a central focus of biology for centuries. Bergmann’s rule – the tendency for animals to reach larger body sizes in colder environments – has been studied in endotherms but with mixed support. However, phylogenetically informed tests of this rule in ectotherms remain scarce, and there [...]
Separating good from bad – a methodological assessment of the critical temperature that separates stressful and permissive temperatures in ectotherms
Published: 2026-03-11
Subjects: Ecology and Evolutionary Biology, Life Sciences
Context and aim: Estimating the thermal limits of ectothermic organisms is critical for predicting their responses to climate change. A key physiological threshold in this context is the critical temperature (Tc), which separates the permissive temperature range, where organisms maintain homeostasis and complete their life cycle, from the stressful range, where thermal stress causes physiological [...]
Population genomics of Uperoleia daviesae (Anura: Myobatrachidae) highlights the vulnerability of naturally fragmented short-range endemics to urban development
Published: 2026-03-10

Urbanisation and land use change threaten short-range endemic amphibians. Uperoleia daviesae, the Howard River toadlet, is a threatened frog species endemic to sandsheet heath, a unique, naturally patchy mosaic of habitats near Darwin in Australia’s Northern Territory. We generated a chromosome-level genome assembly and performed genome-wide SNP analyses using data from 115 individuals across 15 [...]
Who leads diversity efforts in science? Evidence of minority tax in DEI committees of international learned societies in Ecology and Evolutionary Biology
Published: 2026-03-10
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences
Learned societies are key in shaping scientific communities, yet many face inequities rooted in their histories and governance. The inequities can be addressed by Diversity, Equity, and Inclusion (DEI) committees or officers, but little is known about these organisational structures. We present the first analysis of 70 DEI structures across 50 international ecology and evolutionary biology [...]
