While polygyny is common among vertebrates, polygyny with mate fidelity has not yet been demonstrated in amphibians. A recent study by Fábio de Sá and colleagues shows that single male saxicolous frogs share a breeding territory with two females and mate multiple times with them over the course of a breeding season. These authors attribute the evolution of this mating system to the intense competition for territories and mates when access to these resources is scarce.

While much of the work examining the ecological effects of marine warming events focuses on the magnitude and duration of elevated temperatures, a recent study from Amatzia Genin and colleagues investigates how the rate of onset of warming affects the mortality of reef fish in the Red Sea. These authors document fish mortality following two warming events with dramatic increases in temperature and report that piscivores and benthic grazers were disproportionately represented among the found carcasses. Many of these fish were infected with a bacterial pathogen following the warming event. This study points to the rate of warming increase as a critical parameter to be considered when assessing the ecological effects of marine warming events, including those for which the peak temperature is not anomalous.

Climate change has been shown to affect the interannual variation and synchrony among individuals in seed production of masting trees, yet the proximate mechanisms driving these patterns remain unclear. A recent study by Michał Bogdziewicz and colleagues shows that the relationship between weather cues and seed initiation weakens in European beech as warming increases, resulting in progressive asynchrony of seed maturation. This study emphasizes the vulnerability of the relationship between environmental cues and forest reproduction to climate change.
