No evidence for asymmetric sperm deposition in a species with asymmetric male genitalia

The study investigates whether asymmetric male genitalia in Drosophila pachea lead to differential sperm allocation in female storage organs, but finds no evidence for asymmetric sperm deposition.

Zoogeographic patterns on very small spatial scales in rock-dwellingPlectostoma snails from Borneo(Gastropoda: Caenogastropoda: Diplommatinidae)

The paper maps fine-grained distribution patterns of two Plectostoma snail species on small limestone outcrops in Borneo, revealing differences in hybrid zone formation and predation rates between sites.

Children's Species Literacy as Estimated and Desired by Biodiversity Communicators: a Mismatch with the Actual Level

The paper compares biodiversity communicators' estimates of children's species literacy with actual levels, finding a mismatch and differing views on its importance.

A transplantation experiment yields no evidencefor phenotypic plasticity in shell band width in Cepaea nemoralis

A transplantation experiment on Cepaea nemoralis snails found no evidence that habitat change affects shell band width, suggesting little phenotypic plasticity in this trait.

Selection for imperfection: A review of asymmetric genitalia in araneomorph spiders (Araneae: Araneomorphae)

The paper reviews genital asymmetry in araneomorph spiders, finding it more common than previously thought, with detailed documentation of directional asymmetry in Teutamus politus.

Snail shell colour evolution in urban heat islands detected via citizen science

The paper uses citizen science data to show urban heat islands in the Netherlands lead to more yellow snails with dark shell bands in Cepaea nemoralis.

Postmating sexual selection and the enigmatic jawed genitalia of Callosobruchus subinnotatus

The study investigates the function of jaw-like male genitalia in Callosobruchus subinnotatus by ablation experiments, finding that these structures increase female egg production rather than sperm competition success.
