Global exposure risk of frogs to increasing environmental dryness
Published: 2024-02-08
Subjects: Comparative and Evolutionary Physiology, Ecology and Evolutionary Biology, Zoology
Compared with the risks associated with climate warming and extremes, the risks of climate-induced drying to animal species remain understudied. This is particularly true for water-sensitive groups, such as anurans (frogs and toads), whose long-term survival must be considered in the context of both environmental changes and species sensitivity. Here, we mapped global areas where anurans will [...]
The impact of acoustic signalling on offspring performance varies between three biparentally caring species
Published: 2024-02-08
Subjects: Social and Behavioral Sciences
Communication plays a fundamental role in the evolution of any form of cooperative behaviour such as parental care. However, it can be challenging to understand the specific role of certain signals and how they might have evolved into complex communication systems. To investigate what effect a lack of acoustic communication can have on brood care and offspring performance, we silenced parents of [...]
Large-scale spatio-temporal variation in vital rates and population dynamics of an alpine bird
Published: 2024-02-01
Subjects: Applied Statistics, Ecology and Evolutionary Biology, Population Biology, Statistical Models
Quantifying temporal and spatial variation in animal population size and demography is a central theme in ecological research and important for directing management and policy. However, this requires field sampling at large spatial extents and over long periods of time, which is not only prohibitively costly but often politically untenable. Participatory monitoring programs (also called citizen [...]
Sexual system variation in legumes (Leguminosae): underpinning genomic study with new tools to describe inflorescence morphology
Published: 2024-02-01
Subjects: Biology, Botany, Plant Biology, Plant Breeding and Genetics Life Sciences, Plant Sciences
Although the great majority of legume species are cosexual with hermaphrodite flowers, a variety of sexual systems are observed in the family, including monoecy, andromonoecy, androdioecy and dioecy. Such broad terms conceal much variation, details that may be of importance in understanding the evolutionary and ecological basis of reproductive systems. This variation is often inadequately [...]
Selection versus Transmission: Quantitative and Organismic Biology in Antibiotic Resistance
Published: 2024-02-01
Subjects: Life Sciences, Medicine and Health Sciences
We aimed to determine the importance of selection (mostly dependent on the anthropogenic use of antimicrobials) and transmission (mostly dependent on hygiene and sanitation) as drivers of the spread of antibiotic-resistant bacterial populations. The first obstacle to estimating the relative weight of both independent variables is the lack of detailed quantitative data concerning the number of [...]
What is the evidence that counter-wildlife crime interventions are effective for conserving African, Asian, and Latin American wildlife directly threatened by exploitation? A Systematic Map
Published: 2024-02-01
Subjects: Ecology and Evolutionary Biology
1. Counter-wildlife crime interventions ̶ those that directly protect target wildlife from illegal harvest/persecution, detect and sanction rule-breakers, and interdict and control illegal wildlife commodities ̶ are widely applied to address biodiversity loss. This systematic map provides an overview of the literature on the effectiveness of counter-wildlife crime interventions for conserving [...]
How bottlenecks shape adaptive potential: from theory and microbiology to conservation biology
Published: 2024-02-01
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences
Wild populations frequently undergo demographic changes that can destabilize their persistence and, thus, the equilibrium of ecosystems. For instance, habitat loss due to human activities leads to a drastic population size reduction, a process called a bottleneck. By reducing genetic diversity, a bottleneck may prevent a population from adapting to subsequent environmental changes. In the context [...]
Adult telomere length is positively correlated with survival and lifetime reproductive success in a wild passerine
Published: 2024-02-01
Subjects: Evolution
Explaining variation in individual fitness is a key goal in evolutionary biology. Recently, telomeres, repeating DNA sequences capping the ends of chromosomes, have gained attention as a biomarker for body state, individual quality, and ageing. However, existing research has provided mixed evidence for whether telomere length correlates with fitness components, including survival and reproductive [...]
The relative contribution of acoustic signals versus movement cues in group coordination and collective decision-making
Published: 2024-01-30
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
To benefit from group living, individuals need to maintain cohesion and coordinate their activities. Effective communication thus becomes critical, facilitating rapid coordination of behaviours and reducing consensus costs when group members have differing needs and information. In many bird and mammal species, collective decisions rely on acoustic signals in some contexts but on movement cues in [...]
Satellite observations reveal a positive relationship between trait-based diversity and drought response in temperate forests
Published: 2024-01-30
Subjects: Life Sciences
Mapping and predicting ecosystem responses to climate extremes is crucial in the face of global change. To what extent the behavior of non-experimental systems at large scales corresponds to the relationships discovered in biodiversity-ecosystem functioning (BEF) experiments remains unclear. We investigated the relationship between remotely-sensed trait-based diversity and drought responses in [...]
The Distraction Function of Extrafloral Nectaries: Keeping Ants Away From Flowers and Preventing Disruption of Pollination
Published: 2024-01-30
Subjects: Desert Ecology, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
In exchange for extrafloral nectar, ants deter herbivores from the plants, reducing the amount of herbivory they suffered. However, this defensive mutualism can sometimes have negative effects on plants, as ants may also visit flowers, deterring pollinators and reducing plant fitness. The Distraction Hypothesis posits that extrafloral nectaries (EFNs) have the function of attracting ants and [...]
Multiple habitat graphs: how connectivity brings forth landscape ecological processes
Published: 2024-01-30
Subjects: Other Ecology and Evolutionary Biology, Population Biology, Terrestrial and Aquatic Ecology
Purpose: Habitat connectivity is integral to current biodiversity science and conservation strategies. Originally, the connectivity concept stressed the role of individual movements for landscape-scale processes. Connectivity determines whether populations can survive in sub-optimal patches (i.e., source-sink effects), complete life cycles relying on different habitat types (i.e., landscape [...]
The genetic basis of a regionally isolated sexual dimorphism involves cortex
Published: 2024-01-29
Subjects: Biology, Evolution, Genetics and Genomics, Other Ecology and Evolutionary Biology, Population Biology
Sexual dimorphisms represent a source of phenotypic variation and result from differences in how natural and sexual selection act on males and females within a species. Identifying the genetic basis of dimorphism can be challenging, especially once it is fixed within a species. However, studying polymorphisms, even when fixed within a population, can provide insights into the genetic basis of [...]
Evolutionary outcomes arising from bistability in ecosystem dynamics
Published: 2024-01-29
Subjects: Life Sciences
While it is known that shallow lakes ecosystems may experience abrupt shifts (ie tipping points) from one state to a contrasting degraded alternative state as a result of gradual envi- ronmental changes, the role of evolutionary processes and the impact of trait variation in this context remain largely unexplored. It is crucial to elucidate how eco-evolutionary feedbacks affect abrupt ecological [...]
Thresholds and prediction models to support the sustainable management of herbivorous insects in wheat. A review

daily calorific intake for countries across the globe. Wheat crops are attacked by a diverse range of herbivorous invertebrates (pests) that cause significant yield loss. It is anticipated that yield loss caused by pests will increase in response to a changing climate. Currently, these pests are primarily controlled using pesticides, however there is an increased need for more sustainable pest [...]
