TL;DR: The variable frequency of paternal care in H. fleischmanni is a response to the fluctuating nature of the climate and resulting hydration requirements of embryos in combination with the allocation of effort to parental care versus mating activity, finding that both the adaptive value of parental care and flexibility in parental behavior are impacted by spatial and temporal conditions.

TL;DR: It is discovered that a brief period of maternal care is widespread and occurs in species previously thought to lack care, and this change is associated with substantial increases in care levels – a pattern supporting the hypothesis that male‐only care evolved via constraints on maternal expenditure.

TL;DR: In regions where H. fleischmanni and T. cirrhosus co-occur, both calling males and egg masses were more frequently found on ‘less exposed’ lower surfaces of leaves, where risk of attack from aerial predators may be reduced.

TL;DR: This study demonstrates that embryos can respond to conditions resulting from parental abandonment, and provides insights into how variation in care can affect selection on egg-stage adaptations.

TL;DR: Peru is well known for amphibian diversity and endemism, yet there have been relatively few field studies of glassfrog (Centrolenidae) diversity in this country, and based on phylogenetic analysis of DNA sequences, combined with bioacoustic and morphological analyses of new and available material the authors now recognize 33 species from the country.
