Insect Science, EarlyView.We studied oviposition site selection in a leaf‐mining moth (Stigmella sorbi) on rowan trees (Sorbus aucuparia) in northwestern Russia, assessing larval performance across different shoot types, leaf positions, and leaflets. Larval survival was highest on long vegetative shoots, yet females showed no preference for these optimal sites.

Assessing the Presence, Pattern, and Environmental Correlates of Seasonal Skin Thickening in Anurans
Integrative Zoology, EarlyView.Histological sections, like that of the ventral pectoral skin of Lithobates pipiens, were measured to assess variation in skin thickness throughout the year in three North American anuran species. After correcting for individual body size, we test whether skin thickness changes throughout the year and which factors (environment or life history) explain
