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 [...]
Explanations of the obstetric dilemma: evolutionary conflict exacerbates 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 their recent Nature Ecology and Evolution paper, Webb and colleagues show that chimpanzee pelvises present a tight fit for newborn infants, just like in humans. Their detailed 3D characterization shows that the degree of the squeeze is comparable between humans and chimpanzees, and that both have sexually dimorphic pelvises. The authors challenge the so-called “obstetric dilemma” – the [...]
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 [...]
There is no such thing as an herbivore: incidental and intentional ingestion profoundly affects both herbivores and plant-dwelling invertebrates.
Published: 2025-02-26
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Entomology, Life Sciences, Other Ecology and Evolutionary Biology
Real-life ‘herbivores’ are not the herbivores of our simplistic ecological and behavioral models – real-life herbivores constantly consume other organisms both incidentally and intentionally, with the ‘prey’ usually consisting of plant-dwelling arthropods, smaller invertebrates, and carrion. A remarkable amount of disparate literature has amassed on these phenomena, yet the implications of these [...]
Landscape anthropization drives composition and diversity of butterfly communities at a regional scale
Published: 2025-02-25
Subjects: Biodiversity, Ecology and Evolutionary Biology, Other Ecology and Evolutionary Biology
Aim While landscape anthropization is a key driver of biodiversity change, its effects on communities are underexplored, especially at regional scales. In the Anthropocene, climate and habitat diversity alone are insufficient to explain community structure. However, until recently, ecologists lacked accessible, synthesized data describing anthropization gradients, which limited studies to [...]
Belowground communities in lowlands are less stable to climate extremes across seasons
Published: 2025-02-24
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
Ecological responses to climate extremes vary drastically in different spatiotemporal contexts. For instance, the seasonal timing could be a major factor influencing community responses, but its importance is likely to vary at different spatial settings, such as high or low elevation. Here, we investigate how soil communities at high- and low-elevation sites respond to extreme heat events at [...]
Quantifying changes in fish population stability using statistical early warnings of regime shifts
Published: 2025-02-24
Subjects: Ecology and Evolutionary Biology, Life Sciences, Population Biology
Ecological conservation and management benefits from tools that can foresee impending problems, or those in early stages. Statistical early warnings of regime shifts, which can identify generic changes in system behavior associated with stability loss and potential abrupt changes to a new, distinct state, are theoretically well grounded and have been successfully applied in real-world settings. [...]
Functional assisted migration to sustain ecosystem functions under climate change
Published: 2025-02-21
Subjects: Ecology and Evolutionary Biology, Life Sciences
1. Climate change is rapidly altering habitats, forcing many plant species to shift their distribution. However, slow dispersal rates and habitat fragmentation hinder their ability to track these changes, risking local extinctions and reduced ecosystem functioning. Current management strategies may not suffice to address these challenges. 2. We propose functional assisted migration (FAM) as a [...]
