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 ...

An Easy Method to Sample Headspace Pheromones in the Field

Ethology, EarlyView.
Females of the orb‐web spider Argiope bruennichi produces a pheromone to attract males for mating. Most of our knowledge about the pheromone and its strategical use by the females is known from the laboratory. While we have confidence in the validity of these results, we wanted to make sure and measure pheromones in the field.

Microbial‐Immune Interplay in CNS Autoimmune Diseases: Lessons from Animal Models and Clinical Studies

European Journal of Immunology, Volume 56, Issue 2, February 2026.
Mechanism of action of the intestinal microbiota on CNS autoimmune diseases. Environmental factors shape gut microbiota composition; dysbiosis alters microbial metabolites and antigenic signals. These modulate innate and adaptive immunity, affect barrier integrity, and influence CNS‐resident cells such as microglia and astrocytes, contributing to ...

Does female control and male mating system predict courtship investment and mating outcomes? A comparative study in five widow spider species (genus Latrodectus) tested under similar laboratory conditions

BMC Ecology and Evolution
Background Male courtship investment may evolve in response to the male’s expectation of future mating opportunities or the degree of female control during mating interactions.

Game over: Conflict resolution through strategic growth in an invertebrate

Functional Ecology, Volume 40, Issue 1, Page 36-50, January 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In some multimember groups with unequal partitioning of reproduction and poor breeding opportunities outside the group, natural selection has favoured the evolution of adaptive mechanisms such as strategic growth modulation.

Envenomation by an arachnid (Latrodectus or Steatoda): Case report involving a woman and her female dog

Case Reports, 2020
Introduction: Accidents involving spiders bites usually cause mild medical reactions that lead to local symptoms and, less commonly, systemic effects. The most medically significant spiders belong to the genera Latrodectus and Loxosceles.

Airborne DNA and Spider Webs Outperform Other eDNA Sources for Monitoring Terrestrial Vertebrates

Molecular Ecology Resources, Volume 26, Issue 1, January 2026.
ABSTRACT Understanding the strengths and limitations of different environmental DNA substrates is essential for optimising terrestrial vertebrate surveys and monitoring. However, the performance of newly explored substrates (airborne eDNA, vegetation swabs, spiderwebs) compared to longstanding eDNA sources (water and soil) is uncertain.

Discovery of a Recombinant Human Monoclonal Immunoglobulin G Antibody Against α-Latrotoxin From the Mediterranean Black Widow Spider (Latrodectus tredecimguttatus)

Frontiers in Immunology, 2020
Widow spiders are among the few spider species worldwide that can cause serious envenoming in humans. The clinical syndrome resulting from Latrodectus spp.
