Assessing the Impact of Urbanization on Grasshopper Behaviour—A Fieldwork Approach

Journal of Applied Entomology, EarlyView.
ABSTRACT Urbanization is one of the most significant land‐use changes globally, profoundly impacting biodiversity across taxa. Insects, including grasshoppers (Orthoptera), are particularly sensitive to urban pressures, often exhibiting both morphological and behavioural adaptations.

Titin Is Present in the Elastic Tethers That Connect Separating Anaphase Chromosomes in Crane‐Fly Spermatocytes

Cytoskeleton, Volume 83, Issue 7, Page 496-514, July 2026.
ABSTRACT Elastic tethers connect telomeres of separating chromosomes in anaphase of animal cells. Immunofluorescence staining of titin in crane‐fly spermatocytes, using 4 different antibodies, shows that the giant elastic protein titin seems to be a component of mitotic tethers: titin “strands” extend between separating chromosomes, connecting their ...

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.

Impact of Female Mating Status on Male Courtship Behaviour in a Sexually Cannibalistic New Zealand Fishing Spider

Ethology, Volume 132, Issue 6, Page 373-384, June 2026.
Scoring of male courtship behaviour in Dolomedes minor revealed no effect of female mating status on courtship duration or sequence structure, but males delayed the initiation of courtship when encountering previously mated females. ABSTRACT The evolution of male courtship rituals has traditionally been attributed to female mate selection, but may also

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

Integrative Zoology, Volume 21, Issue 3, Page 485-498, May 2026.
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.

An Easy Method to Sample Headspace Pheromones in the Field

Ethology, Volume 132, Issue 5, Page 365-371, May 2026.
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.
