Sperm Transfer Under Behavioral and Morphological Constraints in the Orb‐Web Spider Genus Argiope

open access: yesIntegrative Zoology, EarlyView.
The polygamous mating system of the orb‐web spider genus Argiope provides a model to study the evolution of sperm transfer under morphological and behavioral constraints. This helps us to understand how male and female behavioral and morphological reproductive traits influence sperm transfer.

The Impact of Whole‐Animal Fluid Preservation on the Observed Gut Microbiome of Vertebrates: Implications for the Use of Museum Specimens in Microbiome Research

open access: yesMolecular Ecology Resources, EarlyView.
ABSTRACT The vertebrate gut houses diverse microbial communities that provide insights into their host's ecological and evolutionary histories. Nevertheless, microbiome research has not been distributed equally across host taxonomy, geography and timescales. The millions of fluid‐preserved specimens stored in natural history museums worldwide represent
