Crop species and climate shape amphibian communities and conservation significance of coffee agroforests in the Western Ghats
Published: 2026-04-03
Subjects: Biodiversity, Other Forestry and Forest Sciences, Population Biology, Terrestrial and Aquatic Ecology
Shade coffee agroforests are recognized as refuges for biodiversity and potential allies in conservation across the human-modified tropics. However, biodiversity is strongly influenced by coffee cultivation methods and climates, both of which vary widely and are increasingly dynamic. In this context, one significant but understudied change is the shift in cultivated species from arabica (Coffea [...]
Male scent-marks predict fitness via socio-spatial dominance, but not female choice, in a lacertid lizard
Published: 2026-04-03
Subjects: Animal Sciences, Biodiversity, Life Sciences, Zoology
Chemical communication via scent-marks is widely recognised as a key mediator of sexual selection in lizards, yet their role remains contentious because we mostly ignore how scent-mark composition ultimately impacts male fitness in nature. Male scent-marks are often proposed to function as condition-dependent honest sexual signals mediating female choice, but an arising alternative hypothesis is [...]
On the role of biogeography in the Extended Evolutionary Synthesis
Published: 2026-04-01
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
In the first half of the 20th century, the Modern Synthesis (MS) integrated Mendelian genetics, paleontology, systematics, natural history, common descent, and natural selection. Although the MS has been the guiding paradigm of evolutionary studies since 1950, by the beginning of the 21st century, a new synthesis incorporated themes such as evo-devo, phenotypic plasticity, and epigenetic [...]
Range-wide pangenomics reveals vulnerability and adaptation in a sedentary bird
Published: 2026-03-31
Subjects: Biodiversity, Ecology and Evolutionary Biology, Genetics and Genomics
Structural genetic variants are known to underlie evolutionary adaptations, but have never been evaluated across the entire geographic range of a species. We constructed the first range-wide pangenome to evaluate how such variants may influence conservation efforts of the Montezuma quail (Cyrtonyx montezumae). Profiles of local adaptation, population structure, and genomic diversity all support a [...]
Trophic niche structure of invertebrate-eating bats and birds in West African rice agroecosystems revealed by DNA metabarcoding
Published: 2026-03-30
Subjects: Biodiversity, Biology, Life Sciences
Knowledge of animal community diets is essential for understanding ecosystem functioning. Bats and birds are important groups of invertebrate predators, managing their populations. However, the diets of West African species and the mechanisms shaping them remain poorly understood. In this study, we investigated these mechanisms in agricultural landscapes of Guinea-Bissau using metabarcoding and [...]
Synergies and trade-offs between tree cover expansion efforts within and outside forests to achieve climate, biodiversity and human well-being outcomes
Published: 2026-03-23
Subjects: Biodiversity, Environmental Studies, Nature and Society Relations, Other Forestry and Forest Sciences, Physical and Environmental Geography, Remote Sensing
Increasing tree cover is hailed as a leading climate mitigation strategy, yet there is increasing evidence that there may be trade-offs between trees in different parts of the landscape. Existing science, policy, and practice on natural climate solutions (NCS) assumes that trees outside of forests, for example on farms, homesteads, or in urban areas, are synergistic with forest conservation: if [...]

We [...]
A widespread gap in U.S. Endangered Species Act implementation: Risk of genetic erosion within populations
Published: 2026-03-15
Subjects: Biodiversity, Life Sciences
Despite its importance to fitness and population viability, genetic diversity is rarely incorporated into biodiversity assessments. The recent adoption of indicators of intraspecific genetic diversity by the Convention on Biological Diversity has highlighted the importance of evaluating genetic diversity in wild species. Genetic indicators are useful even in the absence of genetic data because [...]
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.

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 [...]
Echo-dash: Keeping ecologists in the loop with an open source, online ecoacoustic dashboard for interactive exploration of spatiotemporal soundscape data

Subjects: Artificial Intelligence and Robotics, Biodiversity, Databases and Information Systems, Environmental Monitoring, Population Biology, Software Engineering, Terrestrial and Aquatic Ecology
Passive acoustic monitoring (PAM) is being adopted in a range of contexts. Emerging methods facilitate analysis of large-scale data sets, but ecological interpretation of acoustic indices is not straightforward. In addition, the technical and logistical requirements of using emerging AI methods for big data mean that conservation actors increasingly adopt third-party analysis solutions. We argue [...]
