Causes and consequences of variation in early-life telomere length in a bird metapopulation
Published: 2021-10-16
Subjects: Animal Sciences, Biology, Ecology and Evolutionary Biology, Life Sciences, Ornithology, Physiology
1. Environmental conditions during early-life development can have lasting effects on individual quality and fitness. Telomere length (TL) may correlate with early-life conditions and may be an important mediator or biomarker of individual quality or pace-of-life, as periods of increased energy demands can increase telomere attrition due to oxidative stress. Thus, knowledge of the mechanisms that [...]
Predation impacts brain allometry and offspring production in female guppies (Poecilia reticulata)
Published: 2021-10-07
Subjects: Animal Sciences, Biology, Life Sciences, Zoology
Survivorship under predation exerts strong selection on reproductive traits as well as on brain anatomy of prey. However, how exactly predation and brain evolution are linked has not been resolved as current empirical evidence is inconclusive. This may be due to predation pressure having different effects across life stages and/or due to confounding factors in ecological comparisons of predation [...]
A practical conservation tool to combine diverse types of evidence for transparent evidence-based decision-making
Published: 2021-10-01
Subjects: Agriculture, Animal Sciences, Biodiversity, Life Sciences
Making the reasoning and evidence behind conservation decisions clear and transparent is a key challenge for the conservation community. Similarly, combining evidence from diverse sources (e.g., scientific vs non- scientific information) into decision-making is also difficult. Our group of conservation researchers and practitioners has co-produced an intuitive tool and template [...]
Learning from your mistakes: a novel method to predict the response to directional selection
Published: 2021-09-27
Subjects: Animal Sciences, Computational Biology, Ecology and Evolutionary Biology, Evolution, Genetics, Genetics and Genomics, Life Sciences, Other Ecology and Evolutionary Biology, Population Biology
Predicting how populations respond to selection is a key goal of evolutionary biology. The field of quantitative genetics provides predictions for the response to directional selection through the breeder’s equation. However, differences between the observed responses to selection and those predicted by the breeder’s equation occur. The sources of these errors include omission of traits under [...]
Matrix quality determines the strength of habitat loss filtering on bird communities at the landscape scale
Published: 2021-09-19
Subjects: Animal Sciences, Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Ornithology, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology
Habitat loss represent a major threat to biodiversity, however, the modulation of their effects by the non-habitat matrix surrounding habitat patches is still undervalued. The landscape matrix might change community assembly in different ways. For example, low-quality matrices can accentuate environmental filtering by reducing resource availability and/or deteriorating abiotic conditions but they [...]
Nest-boxes alter the reproductive ecology of urban cavity-nesters in a species-dependent way
Published: 2021-08-25
Subjects: Animal Sciences, Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Ornithology, Population Biology
To mitigate the shortage of natural breeding sites in cities, nest-boxes are provided for cavity-nesters. However, these are not the breeding sites these animals originally evolved in and optimised their breeding performance to. It thus remains inconclusive if nest-boxes can provide adequate substitutes, ensuring equivalent fitness returns for breeding animals. Additionally, the majority of [...]
WHY DO INSECTS EVOLVE IMMUNE PRIMING? A SEARCH FOR CROSSROADS
Published: 2021-08-24
Subjects: Animal Sciences, Ecology and Evolutionary Biology, Education, Entomology, Immunity, Immunology and Infectious Disease, Life Sciences
Until recently, it was assumed that insects lack immune memory since they do not have vertebrate-like specialized memory cells. Therefore, their most well studied evolutionary response against pathogens was increased basal immunity. However, growing evidence suggests that many insects also exhibit a form of immune memory (immune priming), where prior exposure to a low dose of infection confers [...]
The potential for physiological performance curves to shape environmental effects on social behaviour
Published: 2021-08-06
Subjects: Animal Sciences, Biology, Life Sciences, Zoology
As individual animals are exposed to varying environmental conditions, phenotypic plasticity will occur in a vast array of physiological traits. For example, shifts in factors such as temperature and oxygen availability can affect the energy demand, cardiovascular system, and neuromuscular function of animals that in turn impact individual behaviour. Here, we argue that non-linear changes in the [...]
Social capital: an independent dimension of healthy ageing
Published: 2021-05-24
Subjects: Animal Sciences, Ecology and Evolutionary Biology, Evolution, Life Sciences, Medicine and Health Sciences, Other Social and Behavioral Sciences, Physiology, Public Health, Research Methods in Life Sciences, Social and Behavioral Sciences, Zoology
Resources that are embedded in social relationships, such as shared knowledge, access to food, services, social support or cooperation, are all examples of social capital. Social capital is recognized as an important age-related mediator of health in humans and of fitness-related traits in animals. A rich social capital in humans can slow senescence and reverse age-related deficits. Animals have [...]
Implementing network approaches to understand the socioecology of human-wildlife interactions
Published: 2021-05-05
Subjects: Animal Sciences, Anthropology, Behavior and Ethology, Biological and Physical Anthropology, Biology, Ecology and Evolutionary Biology, Life Sciences, Social and Behavioral Sciences
Human population expansion into wildlife habitats has increased interest in the behavioral ecology of human-wildlife interactions. To date, however, the socio-ecological factors that determine whether, when or where wild animals take risks by interacting with humans and anthropogenic factors still remains unclear. We adopt a comparative approach to address this gap, using social network analysis [...]
Deploying Ecological Countermeasures as a Biosecurity Imperative

The COVID-19 pandemic has brought biosecurity to the forefront of national security policy. Land use change is a fundamental driver of zoonotic disease outbreaks, yet substantial study is yet required to unravel the mechanisms by which land use-induced spillover operates. Ecological degradation may be the 21st Century’s most overlooked security threat. Within the biosecurity context, we introduce [...]
Ecological Countermeasures for Pandemic Prevention: When Ecological Restoration is a Human Health Imperative

Ecological restoration should be regarded as a public health service. Unfortunately, the lack of quantitative linkages between environmental and human health has limited recognition of these principle. Advent of COVID-19 pandemic provides the impetus for the further discussion. We propose ecological countermeasures as highly targeted, landscape-based interventions to arrest the drivers of land [...]
Validating morphological condition indices and their relationship with reproductive success in great-tailed grackles
Published: 2020-11-19
Subjects: Animal Sciences, Animal Studies, Ecology and Evolutionary Biology, Life Sciences, Ornithology, Social and Behavioral Sciences
Morphological and physiological variation among individuals has the potential to influence multiple life history characteristics such as dispersal, migration, reproductive success, and survival. Individuals that are in better "condition" can disperse or migrate further or more successfully, have greater reproductive success, and survive longer, particularly in years where environmental conditions [...]
Wolf depredation hotspots in France: Clustering analyses accounting for livestock availability
Published: 2020-11-06
Subjects: Agriculture, Animal Sciences, Ecology and Evolutionary Biology, Life Sciences, Zoology
Depredation hotspots are the main source of conflict between humans and large carnivores. When locating depredation hotspots, previous studies have not adjusted for livestock availability, making it impossible for managers to discriminate hotspots resulting from underlying livestock clustering from those due to other factors such as environmental factors. We studied hotspots of wolf depredation [...]

Anthropogenic land use change is the major driver of zoonotic pathogen spillover from wildlife to humans. In response to the global spread of the SARS-CoV-2 virus (the agent of COVID-19 disease), there have been renewed calls for landscape conservation as a disease preventive measure. While protected areas are a vital conservation tool for wildlands, more than 50% of habitable land is now [...]
