Cyclosa Menge, 1866 (Araneidae) Orb‐Weavers Build Stabilimenta That Resemble Larger Spiders

open access: yesEcology and Evolution, Volume 15, Issue 11, November 2025.
The orb‐weaving spider Cyclosa longicauda from Peru constructs unique stabilimenta from detritus and silk that visually resemble a larger spider. This previously undescribed behavior likely functions as a sophisticated anti‐predator strategy, with the structure serving as a decoy to misdirect or repel attacks.

Histological and Gene Expression Analyses of the Arm and Finger Macroglands of Two Hyloxalus Frogs (Dendrobatidae)

open access: yesMolecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Chemical communication during courtship is well documented in salamanders and newts, but its role in frogs is less understood. In some Neotropical poison frogs, males exhibit specialised mucous glands (SMGs) in the hand integument that express high levels of sodefrin precursor‐like factors (SPFs), an amphibian pheromone. Some species also show
