Sex Role–Dependent Behavioral and Architectural Divergence in a Jumping Spider

  Sex Role–Dependent Behavioral and Architectural Divergence in a Jumping Spider ABSTRACT Sex differences in behavior and functional traits are often attributed to differences in mating effort intensity, but the role of sex-specific parental demands remains poorly understood. Using the jumping spider Toxeus maxillosus —where males engage in mate searching and courtship without providing parental care, while females provide extended maternal care from egg attendance to offspring maturity (around 3 months)—we conducted an exploratory investigation into whether these distinct selective pressures led to divergence in spatial behaviors and nest architecture. Results revealed that males and females showed equivalent accuracy, latency, and learning-related performance in both a route-planning test under water stress and a color-pattern associative memory task. In contrast, during nest-construction assays, females built complex, multi-entrance structures that closely matched the container'...

ABSTRACT

Genome sequences of two Stenotrophomonas sp. strains are reported. Isolates were obtained from the venom of the tarantula Stichoplastoris elusinus (Araneae: Theraphosidae) and are closely related to the recently described Stenotrophomonas muris. The announcement highlights the presence of multiple antibiotic resistance genes and their relevance to veterinary and human health.
