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.
Observations on the Reproductive Behavior of a Neotropical Glassfrog, Hyalinobatrachium fleischmanni (Anura: Centrolenidae)
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.
A review of Northern Peruvian glassfrogs (Centrolenidae), with the description of four new remarkable species.
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.
Parents adjust care in response to weather conditions and egg dehydration in a Neotropical glassfrog
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.
Maternal care in a glassfrog: care function and commitment to offspring in Ikakogi tayrona
The finding of maternal care in I. tayrona reveals previously unknown diversity in glassfrog parental care and contributes to emerging evidence that care functions are similar among frogs with female-only and male-only egg attendance.

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.

Recovery of consistent results across multiple genera of glassfrogs is recovered, supporting that hatching plasticity is widespread, ancient, and has been maintained by shared selective trade-offs in this family.
The evolution of extended parental care in glassfrogs: Do egg‐clutch phenotypes mediate coevolution between the sexes?
