Size, Spines, and Nests: What Drives Variation in Death‐Feigning Behavior in Fungus‐Farming Ants?

Integrative Zoology, EarlyView.
We investigated death‐feigning (DF; thanatosis) in fungus‐farming ants, testing how stimulus intensity, morphology, and nest traits shape its occurrence and duration using generalized linear mixed models. Stronger stimuli increased both likelihood and duration, but most variation was structured across species, colonies, and individuals.

Discovering the unseen: A performance comparison of taxonomic classification methods for unknown DNA barcodes

Methods in Ecology and Evolution, EarlyView.
Abstract DNA barcoding and metabarcoding have emerged as cost‐efficient, standardized methods for characterizing local biodiversity. Based on the sequencing of a small targeted gene fragment, it is theoretically possible to identify a wide diversity of taxa by comparing them with reference sequence databases.

VTMaxBox: A reproducible practical tool for measuring voluntary thermal maximum in terrestrial ectotherms

Methods in Ecology and Evolution, EarlyView.
Abstract Thermal traits are central to understanding how ectotherms respond to environmental warming. However, not all thermal traits describe the same biological process. Critical thermal maxima quantify physiological failure, whereas preferred temperatures describe thermal selection under choice conditions.

Crushing and Cutting: Shape Variation and Morphological Integration Between the Claws of Two Swimming Crab Species (Brachyura: Portunidae)

Acta Zoologica, EarlyView.
ABSTRACT This study investigated shape variations and morphological integration between the components of crusher and cutter claws in two species of swimming crabs, Callinectes danae and Callinectes ornatus. The propodi and dactyli of the claws were analysed in males and females of both species, using geometric morphometric techniques to identify ...

A revised classification system of the marronoid clade of spiders (Araneae), based on dense sampling phylogenomics and comparative morphology

Cladistics, EarlyView.
Abstract The marronoid clade is a globally distributed, ecologically diverse group of spiders. It is an important faunal component in both natural and synanthropic environments, and even found in aquatic and extreme habitats such as desert salt flats. The systematics of the marronoid clade has been notoriously unstable due to the widespread character ...

Identifying the exposure of taxonomic, functional, and phylogenetic diversity of steppe birds to renewable energy development

Conservation Biology, EarlyView.
Abstract Biodiversity is globally threatened by human impacts, including land‐use transformation and climate change, which has prompted a rapid transition from fossil fuels to cleaner energy sources, such as photovoltaic (PV) energy. However, utility‐scale PV plants require vast areas and can lead to conflicts with biodiversity conservation, making ...

Coinvasional disruptions to island pollinator networks

Conservation Biology, EarlyView.
Abstract Biological invasions can adversely affect pollinator diversity by threatening the maintenance of animal‐pollinated plant communities. Although most studies have examined single invasive species, accelerating species introductions driven by global trade highlight the need to understand how multiple co‐occurring invaders jointly influence ...

Effects of restoration practices on biodiversity in temperate and boreal forests

Conservation Biology, EarlyView.
Abstract Several restoration practices are used to mitigate and compensate for the negative effects of large‐scale forestry on biodiversity in temperate and boreal forests. A comprehensive synthesis of the benefits of these practices across taxa is missing. We conducted a systematic review and meta‐analysis on this topic.

Experimental Tests of the Dependence of Arthropod Diversity on Plant Diversity

American Naturalist, 1998
Because a diversity of resources should support a diversity of consumers, most models predict that increasing plant diversity increases animal diversity. We report results of a direct experimental test of the dependence of animal diversity on plant diversity.

Diversity and function of arthropod endosymbiont toxins

Trends in Microbiology, 2022
Bacterial endosymbionts induce dramatic phenotypes in their arthropod hosts, including cytoplasmic incompatibility, feminization, parthenogenesis, male killing, parasitoid defense, and pathogen blocking. The molecular mechanisms underlying these effects remain largely unknown but recent evidence suggests that protein toxins secreted by the ...
