Too many choices complicate female frogs’ sex lives
Recent research reveals a surprising complexity in female frog mating behavior. Laboratory studies demonstrate that as the number of male mating calls increases, female frogs exhibit a decreased likelihood of selecting their preferred partners. This phenomenon suggests a potential shift in mating dynamics, possibly offering less dominant males increased opportunities for reproduction. Understanding these nuanced behaviors is crucial for accurate ecological modeling.

Effects of ultraviolet-B radiation on the reproduction, germling growth, and physio-biochemical characteristics of green alga Ulva pertusa (Chlorophyta)
Increased ultraviolet-B (UV-B) radiation, a consequence of ozone depletion, presents a significant global environmental challenge. This study investigates the impact of varying UV-B doses on the green alga *Ulva pertusa*, a species commonly found in shallow, high-radiation intertidal zones. We examined the effects on reproduction, germling development, and key physio-biochemical parameters. Results demonstrate a dose-dependent reduction in propagule density, germination rates, and germling growth, alongside increased oxidative stress and a compensatory, yet ultimately insufficient, antioxidant response.
