Causes of recent changes in bill length in Crozet wandering albatross, a long-lived seabird
Published: 2024-11-21
Subjects: Ecology and Evolutionary Biology, Evolution, Population Biology
Phenotypes are changing in many wild populations, largely in response to environmental changes due to human activities. Phenotypic change can be driven by several mechanisms, with contrasted consequences for the persistence of populations. Identifying those mechanisms is key to understand current responses to human pressures and to predict the future fate of populations. Here we attempt to [...]
Experimentally-induced low flows reveal climate change may shrink trophic niches of mountain stream predators.
Published: 2024-11-21
Subjects: Ecology and Evolutionary Biology
Climate change is projected to decrease snowpack and advance snowmelt in mountain ranges globally–including in California’s Sierra Nevada, where streamflow in snow-dominated rivers is expected to peak up to 2 months earlier, and remain in baseflow conditions for extended periods of time. Predators may be particularly sensitive to low flows, owing to their larger body sizes, higher metabolic [...]
The evolutionary conflict theory of aging
Published: 2024-11-20
Subjects: Biology, Evolution
Why we age is an enduring mystery. This manuscript proposes aging is microevolutionarily opposed, but macroevolutionarily favored. Such a conflict between microevolution and macroevolution is highly unusual since traits that are harmful to the organism are usually harmful to the survival of the species. In the case of aging, however, a shorter lifespan makes a species better able to adapt to a [...]
Foraging actively can be advantageous in heterogeneous environments
Published: 2024-11-17
Subjects: Life Sciences
A wealth of evidence indicates that the existence of active foragers and sit-and-wait foragers is widespread in nature. While active foragers visit foraging sites and leave them randomly, sit-and-wait foragers only do so if the benefit of leaving exceeds the cost. This dichotomy has been documented in the larval and adult stages of Drosophila melanogaster. For instance, when exposed to a [...]
Towards a unified ontology for monitoring ecosystem services
Published: 2024-11-16
Subjects: Life Sciences
The concept of ecosystem services (ES) has greatly evolved since it was first proposed and, as it gained popularity, has been used in diverse applications. Today, ES are an important part of global and national environmental policies. In this context, there is a call for the monitoring of ES to support their management. The proliferation of terms used with the concept of ES may be a barrier to [...]
Effect of bulb type on moth trap catch and composition in UK gardens
Published: 2024-11-15
Subjects: Biodiversity, Ecology and Evolutionary Biology, Entomology, Research Methods in Life Sciences
Abstract 1. A wide variety of light sources are employed to trap moths, differing in brightness and spectrum. Relatively little is known about how these factors affect the resulting sample. 2. We analyse 7 moth trap bulb types using 10 years of records from the Garden Moth Scheme to provide the largest and most comprehensive comparison of moth trap bulb types to date. 3. 125W Mercury Vapour (MV) [...]
The Influence of Light Colour on the Behaviour of Atlantic Cod in an Experimental Setting
Published: 2024-11-15
Subjects: Behavior and Ethology, Marine Biology
Fishing technologies often exploit the visual sensitivity of target species to alter their behaviours. Atlantic cod (Gadus morhua Linnaeus, 1758) are an economically important species, commonly targeted by fisheries in the North Atlantic, yet the behaviour of adult Atlantic cod in reaction to the simultaneous presentation of various light stimuli has not been assessed in an isolated setting to [...]
Do behavioural ecologists misuse the term multivariate?
Published: 2024-11-14
Subjects: Ecology and Evolutionary Biology
Clear communication of procedures and findings is critical for scientific progress. One problem facing many research disciplines is the incorrect labelling in the literature of multivariable (i.e. many Xs) statistical models as multivariate (many Ys). Multivariate and multivariable statistical models are different statistical approaches and should be described as such. I assessed whether [...]
Border biosecurity interceptions for air passengers – assessing intervention methods and analytic tools
Published: 2024-11-14
Subjects: Agriculture, Biosecurity, Life Sciences
At-border interventions are a critical step along the biosecurity continuum, to measure and control the risks associated with the cross-border movement of people and goods. Air passengers are a high-volume pathway for a range of biosecurity risk materials, against which various interventions may be used (e.g., manual searches, detector dogs, x-rays, etc.). Using a large interception database for [...]
Gut microbiome composition and function – including transposase gene abundance - varies with age, but not senescence, in a wild vertebrate
Published: 2024-11-14
Subjects: Bioinformatics, Ecology and Evolutionary Biology, Life Sciences, Microbiology, Ornithology
Studies on wild animals, mostly undertaken using 16S metabarcoding, have yielded ambigous evidence regarding changes in the gut microbiome (GM) with age and senescence. Furthermore, variation in GM function has rarely been studied in such wild populations, despite GM metabolic characteristics potentially being associated with host senescent declines. Here, we used seven years of longitudinal [...]
Prokaryotes Become Larger at High Temperatures but They Do Not Grow Faster
Published: 2024-11-14
Subjects: Education
Metabolic theory posits that metabolism governs the rate at which organisms transform energy into biological work and growth. Thus, it constitutes the main mechanism driving the evolution of organismal growth and size across almost all domains of life. One general prediction of metabolic theory suggests that populations of larger organisms grow more slowly than populations of smaller organisms. [...]
Advancing the spatiotemporal dimension of wildlife–pollution interactions

Subjects: Animal Sciences, Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Environmental Health Life Sciences, Life Sciences, Other Animal Sciences, Other Ecology and Evolutionary Biology, Other Pharmacology, Toxicology and Environmental Health, Pharmacology, Toxicology and Environmental Health, Toxicology, Zoology
Chemical pollution is a pervasive problem and is now considered the fastest-growing agent of global environmental change. Numerous pollutants are known to disrupt animal behaviour, alter ecological interactions, and shift evolutionary trajectories. Crucially, both chemical pollutants and individual organisms are non-randomly distributed throughout the environment. Despite this, the current [...]
Choosing friends in an uncertain world: information reduces relationship stability in a Bayesian learning model of cooperative partnership
Published: 2024-11-14
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
Social animals often form differentiated social relationships with conspecifics. Developing closer partnerships with some than others can facilitate cooperative interactions in which individuals share resources or risk. When choosing a partner, individuals face a decision: a known partner might be sub-optimal if better options are available, but switching partners can be risky if others' [...]
Social bonds between non-kin are common, but less stable, in a mixed-related society
Published: 2024-11-13
Subjects: Behavior and Ethology
Members of social groups often form social relationships, which are known to carry important fitness benefits. Kin selection predicts that these relationships should be prevalent between kin, yet there is increasing evidence that, in societies that feature a mixture of related and unrelated individuals, social bonds are also formed with non-kin. Nevertheless, quantitative research on non-kin [...]
