Offspring Defensive Investment Covaries With Brood Value in a Female Cobweb Spider

open access: yesIntegrative Zoology, EarlyView.
We performed a thorough field investigation on the web architectures of Campanicola campanulata to research its cobweb architecture variation under the condition of whether it carried egg sacs, in order to test the theory of its brood value. Our results demonstrate that retreat construction in female cobweb spiders is modulated by brood value.

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

open access: yesIntegrative 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.

Fragment Edges Benefit a Common Predator of Pollinators via Bottom‐Up Effects

open access: yesIntegrative Zoology, EarlyView.
This study investigated the hypotheses regarding the effects of habitat fragmentation on spider biomass and causing bottom‐up or top‐down effects on multi‐trophic relationships. ABSTRACT Defaunation following habitat fragmentation typically threatens predators at higher trophic levels, which further alter prey and plants via top‐down effects.

The First Quantitative Evidence of Ontogenetic Growth in the Early Cambrian Ecdysozoan Worm Cricocosmia jinningensis Reveals the Earliest Energy Reallocation

open access: yesIntegrative Zoology, EarlyView.
We report the first ontogenetic information for the compression‐preserved Cambrian ecdysozoan worm Cricocosmia jinningensis. Its mosaic growth strategy unifies panarthropod and priapulid developmental patterns. Sclerite allometry reverses at the juvenile‐to‐adult transition, providing the earliest evidence of developmental resource allocation ...

Descriptron‐GBIF Annotator: A browser‐based platform for crowdsourced morphological annotation of biodiversity images

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract The biodiversity crisis demands new approaches to describing and characterising species that can scale beyond the capacity of professional taxonomists alone. Hundreds of millions of specimen images are now openly available, yet almost none carry structured information about the morphology they depict. We present the Descriptron‐GBIF Annotator,
