Hyperkeratosis of (a) the footpads and (b) the nasal planum. ABSTRACT Background Canine leishmaniosis (CanL) due to Leishmania infantum remains common, and veterinarians do not always follow scientifically sound approaches for diagnosis, treatment and prevention. Objectives To provide consensus guidelines for diagnosis and evidence‐based guidelines for

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

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
