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.

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
Subjects: Ecology and Evolutionary Biology
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 [...]
Seven principles for engaging schools with nature: pooling the expertise of teachers and nature educators
Published: 2026-03-05
Subjects: Ecology and Evolutionary Biology, Education, Environmental Studies, Nature and Society Relations
Nature connection in schools can address several issues faced in both environmental and educational fields. However, guidance is limited and many aspects can feel daunting or risky for schools under multiple other constraints. As a group of researchers, schoolteachers, and nature educators, we have co-produced seven guiding principles for integrating nature within UK schooling, particularly in [...]
Measuring biodiversity impact, change and restoration opportunity for business
Published: 2026-03-04
Subjects: Biodiversity, Ecology and Evolutionary Biology
Most pressures that cause biodiversity loss are driven by economic activity. There is significant interest from the private sector in understanding impacts and dependencies of business activity on biodiversity. However, measuring the impacts of direct and indirect business activities on biodiversity, including species, at multiple scales remains a considerable challenge. There are no currently [...]
Do harbour porpoise mortality records reflect living population structure? A matrix population model diagnostic
Published: 2026-03-04
Subjects: Ecology and Evolutionary Biology, Population Biology
Effective conservation of marine mammals depends on reliable demographic information, yet acquiring such data for highly mobile cetaceans is challenging. Harbour porpoises (Phocoena phocoena) are widely used as sentinel species, but much of what is known about their demography comes from opportunistic sources, such as stranding and bycatch records. While invaluable, these data may be subject to [...]
Three decades later: A resurvey of vegetation biodiversity in Italian coastal dunes
Published: 2026-02-26
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
Mediterranean coastal dunes have undergone substantial transformations over the last 70 years due to increasing anthropogenic pressure and environmental change. However, most studies on dune vegetation dynamics have been conducted at local scales, limiting our understanding of long-term plant diversity trends across broader regions. Here, we present the first national-scale assessment of [...]
pynnotate: a flexible tool for retrieving and processing GenBank data in molecular evolution research and education
Published: 2026-02-26
Subjects: Bioinformatics, Ecology and Evolutionary Biology, Evolution
Pynnotate is a Python-based tool designed for automated retrieval, parsing, and extraction of annotated gene sequences from GenBank records. The tool addresses the common challenges researchers face when working with GenBank data, including inconsistent gene nomenclature, redundant sequences, and the need for standardised gene extraction across multiple taxa. Pynnotate operates through both a [...]
Beyond Observed Diversity: A Completeness-Based Invasion Theory
Published: 2026-02-26
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Population Biology, Terrestrial and Aquatic Ecology
Charles Elton proposed that species-rich communities resist invasion better, but support is mainly from local studies, possibly because studies use observed richness alone, ignoring the dark diversity. I propose Completeness-Based Invasion Theory, linking invasibility inversely to community completeness, an index linking observed and dark diversity, enabling unified insights across scales.
Tapping into symbiosis to advance human microbiome research
Published: 2026-02-25
Subjects: Bacteriology, Ecology and Evolutionary Biology, Environmental Microbiology and Microbial Ecology Life Sciences, Life Sciences, Other Microbiology, Pathogenic Microbiology
In human microbiome research, the term commensal is often used to describe organisms that benefit their hosts. In ecology, where the term originates, a commensal organism has no impact on its host, whereas a mutualist organism benefits its host. While others have recognized this discrepancy in terminology use, old habits are hard to break, and the human microbiome community has continued in this [...]
A new conceptual framework for host-microbe symbiosis
Published: 2026-02-25
Subjects: Ecology and Evolutionary Biology, Life Sciences
Host-microbe relationships are studied across biological disciplines, with unique but overlapping conceptual frameworks arising from each of them. Without a unified framework that can be applied across all host-microbe symbioses, we cannot do the interdisciplinary work necessary to understand the underlying rules that govern them. Here I present a new conceptual framework for host-microbe [...]
A comparison of methods to assess selective disappearance and quantify ageing
Published: 2026-02-25
Subjects: Ecology and Evolutionary Biology, Research Methods in Life Sciences
1. Age-dependent change in traits at the population-level level can diverge from the within-individual ageing trajectory due to selective disappearance, the biased removal or death of individuals with certain phenotypes. 2. Commonly used methods to assess, and account for, selective disappearance have been developed for relatively simple settings. As such, we currently lack a clear understanding [...]
