Socioecology and the role of scramble competition
Published: 2025-03-11
Subjects: Animal Sciences, Animal Studies, Anthropology, Behavior and Ethology, Biological and Physical Anthropology, Biology, Ecology and Evolutionary Biology, Evolution, Life Sciences, Zoology
Ecological explanations for social organization and behavior are central to behavioral ecology. Unfortunately, the continuing mismatch between theoretical predictions and some empirical data led to increasingly complex hypotheses with numerous factors, raising doubts about their predictive value or even falsifiability. Moreover, several taxon-specific socioecological hypotheses have been [...]
Historical legacies of spatial and temporal climate exposure on thermal physiology shape butterfly vulnerability to recent climate change
Published: 2025-03-11
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Few observations are more indelible in ecology than widespread variation in the spatial and temporal occurrence of species. Although the mechanistic underpinnings of such variation are likely multifarious, temperature is argued to be a key driver. Understanding how temperature shapes species ranges and seasonal activity not only provides insights into historical biogeographic patterns, but also [...]
Minimal viable sound systems for language evolution
Published: 2025-03-10
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences, Neuroscience and Neurobiology, Physiology, Systems Biology
Human vocal gamut covers 3000 unique speech sounds comprising the world’s languages, with each new speaker having to learn the sounds of its new language. Since large, expandable repertoires are facilitated by vocal learning, this capacity has long been considered a prerequisite for speech and language evolution. The postulation of a vocal learning and repertoire size ceiling has, however, never [...]
Pattern-informed energetics: Energy allocation modeling for predicting trait variation and population persistence
Published: 2025-03-07
Subjects: Ecology and Evolutionary Biology, Life Sciences, Physiology
Energetics drive emergent ecosystem processes, shaping behavior and population dynamics in response to environmental conditions. While energy budget models can be used to effectively link resource dynamics to fitness outcomes, they often lack empirical grounding for energy allocation under resource constraints. Here, we introduce the Pattern-Informed Energetics (PIE) framework, which leverages [...]
Modelling the distribution of the tick Ixodes ricinus in England and Wales using passive surveillance data from citizen science reports
Published: 2025-03-07
Subjects: Ecology and Evolutionary Biology, Entomology, Environmental Public Health, Public Health
Background: The tick Ixodes ricinus is the most common tick species in the UK and a significant vector of Borrelia burgdorferi s.l. (causative agent of Lyme borreliosis) and Tick-Borne Encephalitis virus (TBEv) to humans and Anaplasma phagocutphilum, Babesia divergens and louping ill virus to animals.Methods: The Tick Surveillance Scheme (TSS) administered by the UK Health Security Agency (UKHSA) [...]
AmphiTherm: a comprehensive database of amphibian thermal tolerance and preference
Published: 2025-03-07
Subjects: Ecology and Evolutionary Biology, Life Sciences
Thermal traits are crucial to our understanding of the ecology and physiology of ectothermic animals. While rising global temperatures have increasingly pushed research towards the study of upper thermal limits, lower thermal limits and thermal preferences are essential for defining the thermal niche of ectotherms. Through a systematic review of the literature in seven languages, we expanded an [...]
Individual variation in perceived density and its impacts on the realization of ecological niches
Published: 2025-03-06
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Organisms gain information about their local environment using different senses. Variation in both reception and assessment of stimuli leads to differences among individuals in their perception of environments. Here, we highlight the importance of acknowledging and investigating such individual differences by focusing on perceived density, the individual’s assessment of local density. We [...]
Indirect effects dominate ecosystem service losses in response to agricultural intensification
Published: 2025-03-05
Subjects: Agriculture, Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Feeding a growing human population while preventing biodiversity loss is a major challenge. Land conversion impacts multiple ecosystem services (ESs), including food production and biodiversity-dependent services; yet, the role of indirect effects on ESs within this context, such as parasitoids boosting crop yield by controlling herbivores, remains poorly understood. Using species-network data [...]
Tracheal chambers as a key innovation for high frequency emission in bat echolocation.
Published: 2025-03-05
Subjects: Animal Sciences, Biology, Ecology and Evolutionary Biology, Evolution, Life Sciences, Zoology
Key innovations play a crucial role in driving biodiversity and facilitating evolutionary success by enabling organisms to adapt to various ecological niches through the diversification of phenotypic traits. These innovations have been observed in different vertebrate clades, such as mammals evolving hypsodonty to graze on contemporary grasses and bats with the evolution of echolocation, [...]
Exploring the interplay of epigenetics and individualization
Published: 2025-03-04
Subjects: Ecology and Evolutionary Biology, Evolution
Considering individual differences enhances our understanding of eco-evolutionary processes. Epigenetic modifications, which enable the same genotype to produce different phenotypes, may serve as a key proximate mechanism underlying these differences. We propose that epigenetic mechanisms mediate the realization of individualized niches. This process is best understood by distinguishing between [...]
Agroecological farming promotes yield and biodiversity but may require subsidy to be profitable
Published: 2025-03-04
Subjects: Agriculture, Biodiversity, Ecology and Evolutionary Biology, Entomology, Life Sciences, Other Ecology and Evolutionary Biology
1. Intensive arable agriculture uses agrochemicals to replace ecosystem services (e.g. pest control and soil health) while simultaneously degrading others (e.g. pollination). Agroecological farming aims to reduce this reliance. Whether these practices maintain yields at a scale relevant to farm business viability is unclear. 2. In a 4-year replicated study across 17 English farms we assessed [...]
Beyond the obstetric dilemma: evolutionary maternal-fetal conflict causes health problems in pregnancy and childbirth
Published: 2025-03-03
Subjects: Anthropology, Biological and Physical Anthropology, Ecology and Evolutionary Biology, Evolution, Genetics, Life Sciences, Maternal and Child Health, Medicine and Health Sciences, Translational Medical Research
In excellent recent work, Webb and colleagues challenged the so-called “obstetric dilemma”—the long-standing hypothesis that human childbearing is particularly dangerous because we have a narrow pelvis but large infant heads (we are bipedal and smart). They showed that humans and chimpanzees have a comparable fetal-pelvic squeeze. What, then, causes risky childbirth in humans? Webb and colleagues [...]
The effect of sex, age, and boldness on inhibitory control
Published: 2025-03-03
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
Inhibitory control requires an individual to suppress impulsive actions in favour of more appropriate behaviours to gain a delayed reward. It plays an important role in activities such as foraging and initiating mating, but high within-species variation suggests that some individuals have greater inhibitory control than others. A standard index of inhibitory control used in many taxa is measuring [...]
Heterogeneous individuals impede the establishment of cultures in animal groups
Published: 2025-02-27
Subjects: Ecology and Evolutionary Biology
Social learning facilitates the diffusion of novel behaviours (i.e., inventions) through groups and is a key component in the development of culture. The speed with which an invention spreads through a group is largely determined by the strength of social connections and network structure; however, research concerning the establishment of inventions (i.e., culture) has typically overlooked that [...]
No refuge at the edge for European beech as climate warming disproportionately reduces masting at colder margins
Published: 2025-02-27
Subjects: Ecology and Evolutionary Biology, Forest Sciences, Physical and Environmental Geography
Reproduction is vital for forest resilience to climate change, as tree populations depend on adequate seed production to recover demographically from disturbances and migrate to more suitable sites. Neglecting reproduction in projections of habitat suitability and range shifts risks overestimating forest resilience to climate change. For many tree species, including European beech (Fagus [...]
