Unravelling Evolutionary Dynamics of Female Sexual Cannibalism and Male Reproductive Strategies in Spiders

Integrative Zoology, EarlyView.
Sexual cannibalism (SC), where one mating partner consumes the other in the context of mating, is especially prevalent among spiders. However, the evolution of SC in spiders is still not fully understood. We review key hypotheses for SC and explore how female‐initiated SC has driven the evolution of various male counter‐adaptations to mitigate its ...

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

Integrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Multi‐Omics Analysis Reveals Coordinated Adaptations in Genes, Metabolism, and Gut Microbiota Underpinning Herbivory in Lordiphosa Flies

Integrative Zoology, EarlyView.
Multi‐omics analysis reveals that herbivorous adaptation in Lordiphosa flies arises from coordinated interactions across the genome, transcriptome, and gut microbiota: genomic expansions of detoxification (e.g., cytochrome P450s) and carbohydrate metabolism gene families, transcriptomic upregulation of energy pathways like lipid oxidation and ...

Gonadal Development–Related Genes and a Male‐Specific Genetic Marker Identified in the Endangered Sichuan Taimen (Hucho bleekeri)

Integrative Zoology, EarlyView.
Integrated transcriptomic and proteomic analyses were used to validate gonadal development–related genes and to identify a sex‐specific molecular marker in Hucho bleekeri. ABSTRACT Sex determination and differentiation represent fundamental topics in reproductive biology. Sichuan taimen (Hucho bleekeri), a first‐class national protected fish species in

The Australian Hydromyine Rodents—Their Interspecific Diversity and Reproductive Biology: A Review

Integrative Zoology, EarlyView.
There are two major groups, the Rattus species and the Hydromyini, in Australia. Clearly, the hydromyine rodents, unlike the Rattus genus, exhibit a diverse array of reproductive biological traits in both males and females, the full evolutionary significance of which has yet to be ascertained.
