There is no such thing as an herbivore: incidental and intentional ingestion profoundly affects both herbivores and plant-dwelling invertebrates.

Eric Lopresti, Eric F. LoPresti

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

Baptiste Bongibault, Laurent Godet, Régis Morel, et al.

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

Gerard Martínez De León, Ludovico Formenti, Jörg-Alfred Salamon, et al.

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

Jonathan A. Walter, Levi Lewis, James Hobbs, et al.

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

Koenraad Van Meerbeek, Senne Spreij, Marijke Geuskens, et al.

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 [...]

Projected climate change scenarios spatially decouple desert EFN-ant mutualisms

Jenna L. Braun, Chris Lortie

Published: 2025-02-21
Subjects: Desert Ecology, Ecology and Evolutionary Biology, Life Sciences

Aim: Climate change is changing species distributions globally, but predicting these impacts on assemblages and their spatial overlaps under future scenarios is an ongoing challenge. Here, we explore how climate change influences distributions among two mutualistic assemblages. Location: The Mojave and Colorado Deserts, California, United States Methods: We developed stacked species [...]

estar: An R package to measure ecological stability

Ludmilla Figueiredo, Cédric Scherer, Stephanie Kramer-Schadt, et al.

Published: 2025-02-21
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology

1. Assessing ecological stability across populations or communities is a prime goal in biodiversity monitoring and conservation research. Quantifying stability is not trivial because its different aspects can be measured with various metrics. However, to date, no software enables measuring different stability metrics on ecological time-series data. 2. We present the estar R package that [...]

Repeated mitochondrial capture with limited genomic introgression in a lizard group

Wesley Read, Rebecca J Laver, Ching Ching Lau, et al.

Published: 2025-02-19
Subjects: Ecology and Evolutionary Biology, Evolution, Genetics and Genomics, Life Sciences

Mitochondrial introgression is common among animals and is often first identified through mitonuclear discordance — discrepancies between evolutionary relationships inferred from mitochondrial DNA (mtDNA) and nuclear DNA (nuDNA). Over recent decades, genomic data have also revealed extensive nuclear introgression in many animal groups, with implications for genetic and phenotypic diversity. [...]

Climate change intensifies plant-pollinator mismatch and increases secondary extinction risk for plants in northern latitudes

Shijia Peng, Aaron M Ellison, Charles Davis

Published: 2025-02-19
Subjects: Biodiversity, Ecology and Evolutionary Biology

Climate change is altering the timing of species’ life-cycle events (i.e., phenology), but the rates of phenological shifts vary across taxa. These mismatches in phenological response may disrupt interactions between interdependent species, such as plants and their pollinators, which may lead to reduced plant reproduction via pollen limitation and contribute to secondary extinction risks for [...]

Northward expansion of the thermal limit for the tick Ixodes ricinus over the past 40 years

Daniele Da Re, Gaelle Gilson, Quentin Dalaiden, et al.

Published: 2025-02-14
Subjects: Bioinformatics, Biology, Ecology and Evolutionary Biology, Entomology, Life Sciences, Population Biology

The tick Ixodes ricinus is the main pathogen vector in Europe. Many speculations have been made about the effect of past climate change on the potential distribution of this ectothermic organism, despite a poor understanding of how climate change has resulted in distribution changes to date. In this study, we used a public cross-sectional dataset of I. ricinus abundance at the northern edge of [...]

Algorithm selection for optimal ecological monitoring design

Kari E Norman, Timothée Poisot

Subjects: Biodiversity, Bioinformatics, Ecology and Evolutionary Biology

Comprehensive monitoring of biodiversity to direct conservation action is foundational to addressing the ongoing biodiversity crisis. As integrative monitoring programs increasingly come online in response to multilateral biodiversity agreements, establishing best practices for optimal design is critical. Selecting the appropriate algorithm for identifying sample sites is both necessary for [...]

Location-scale Meta-analysis and Meta-regression as a Tool to Capture Large-scale Changes in Biological and Methodological Heterogeneity: a Spotlight on Heteroscedasticity

Shinichi Nakagawa, Ayumi Mizuno, Kyle Morrison, et al.

Published: 2025-02-11
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology

Heterogeneity is a defining feature of ecological and evolutionary meta-analyses. While conventional metal-analysis and meta-regression methods acknowledge heterogeneity in effect sizes, they typically as-sume this heterogeneity is constant across studies and levels of moderators (i.e., homoscedasticity). This assumption could mask potentially informative patterns in the data. Here, we introduce [...]

Seeing herbaria in a new light: leaf reflectance spectroscopy unlocks predictive trait and classification modeling in plant biodiversity collections

Dawson M White, Jeannine Cavender-Bares, Charles Davis, et al.

Published: 2025-02-10
Subjects: Biodiversity, Bioinformatics, Botany, Ecology and Evolutionary Biology, Integrative Biology, Life Sciences

Reflectance spectroscopy is a rapid method for estimating traits and discriminating species. Spectral libraries from herbarium specimens represent an untapped resource for generating broad phenomic datasets across space, time, and taxa. We conducted a proof-of-concept study using trait data and spectra from herbarium specimens up to 179 years old alongside data from recently dried, pressed [...]

Harnessing meta-analyses’ insights in ecology and evolution research

Pietro Pollo, April Robin Martinig, Ayumi Mizuno, et al.

Published: 2025-02-10
Subjects: Ecology and Evolutionary Biology

Meta-analyses are powerful tools to synthesise the literature in several fields of study, including ecology and evolution. However, it remains uncertain whether ecologists and evolutionary biologists fully comprehend meta-analyses’ findings or effectively apply them when citing these studies in their own research. Here, we first discuss key meta-analytical concepts and provide a guide to [...]

Geography, taxonomy, extinction risk and exposure of fully migratory birds to droughts and cyclones

Henry Hakkinen, Rhys G. G. Preston-Allen

Published: 2025-02-10
Subjects: Ecology and Evolutionary Biology, Life Sciences

Anthropogenic climate change is predicted to drive unprecedented increases in the frequency and intensity of extreme climatic events, such as drought and cyclones. The impacts of these events on fully migratory species could be particularly severe and have cascading effects on the functioning of many ecosystems. We explore the relationships between geography, taxonomy, extinction risk and the [...]
