Linking specific ecological factors to the evolution of parental care pattern and mating system is a difficult task of key importance. We provide evidence from comparative analyses that an ecological factor (breeding pool size) is associated with the evolution of parental care across all frogs. We further show that the most intensive form of parental care (trophic egg feeding) evolved in concert with the use of small pools for tadpole deposition and that egg feeding was associated with the… 
The biparental care hypothesis for the evolution of monogamy: experimental evidence in an amphibian
The hypothesis that selection for biparental care has driven the evolution of monogamy in an amphibian is tested and it is demonstrated that in addition to egg attendance and tadpole transport, male parental care is critical for offspring survival throughout larval development.
Biparental care and social monogamy in the Peruvian poison frog, Ranitomeya flavovittata (Anura: Dendrobatidae)
The parental behaviour and mating system of the Peruvian poison frog R. flavovittata is investigated and social monogamy is described to be one of the major evolutionary factors leading to a monogamous mating system.
Does environmental variability explain male parental care in a burying beetle
The load-lightening hypothesis, which holds that biparental care benefits future reproduction by lowering the costs of reproduction, is tested, and evidence of reproductive restraint associated with the higher temperature treatment in delayed egg-laying and increased feeding during second broods is found.
Strong male/male competition allows for nonchoosy females: high levels of polygynandry in a territorial frog with paternal care
It is hypothesized that female polyandry in this species has evolved because of enhanced offspring survival when paternal care is allocated to multiple partners.
The evolution of parental care, aposematism and color diversity in Neotropical poison frogs
This Special Issue demonstrates the breadth of evolutionary ecology research occurring on Neotropical poison frogs (Dendrobatidae) and draws attention to the incredible diversity of the poison frogs themselves, and the potential for research programs focusing on speciation, the evolution of toxicity, color pattern diversity, Mullerian and Batesian mimicry, sexual selection, mating systems and parental care.
Competitive Interactions in Phytotelmata—Breeding Pools of Two Poison-Dart Frogs (Anura: Dendrobatidae) in Costa Rica
Study of size-based habitat selection of artificial phytotelmata for deposition of tadpoles in two species of poison-dart frogs in Costa Rica found that the predaceous D. auratus selected large- and medium-sized pools, whereas O. granulifera selected all pool sizes but had a preference for small pools.
The power of the seasons: rainfall triggers parental care in poison frogs
It is suggested that R. variabilis, a species that typically isolates its cannibalistic offspring, has evolved a plastic feeding behaviour with regard to the risk of phytotelmata desiccation, and is interpreted that parents provide older tadpoles with younger ‘trophic’ tadpole in order to accelerate their development and save them from impending Desiccation.
The evolution of parental care in insects: A test of current hypotheses
Insect care evolution most closely resembled amphibian care in general trajectory, and was more labile in Holometabola than in Hemimetabola.
The evolution of parental care diversity in amphibians
It is shown that egg attendance, arguably one of the simplest care behaviours, is gained and lost faster than any other care form, while complex adaptations, like brooding and viviparity, are lost at very low rates, if at all.
Patterns of parental care in vertebrates
Vertebrate groups that show great variation in care types, like teleost fishes and shorebirds, have been particular useful models in the search for a better understanding of the evolution of parental behaviour.


Divergence in parental care, habitat selection and larval life history between two species of Peruvian poison frogs: an experimental analysis
This work manipulated breeding pool size in order to demonstrate experimentally that breeding habitat selection strategy has evolved in concert with changes in parental care and mating system and manipulated intra‐ and interspecific larval interactions to demonstrate that larval adaptation to the use of very small pools for breeding affected the evolution of larval competition and cannibalism.
Phytotelm size in relation to parental care and mating strategies in two species of Peruvian poison frogs
The results are consistent with the hypothesis that a key ecological difference between these species, involving the size of pools typically used for reproduction, is strongly associated with the evolution of biparental care and monogamy in D. imitator.
A cost of polygyny is unlikely to drive a female care strategy to fixation on its own; however, if caring males suffer a cost of lost mating opportunities then a cost-of-polygyny may destabilize male care and result in the evolution of uniparental female care.

A stage model traces key behavioural tactics and life-history traits that are involved in the transition from promiscuity with no parental care, the mating system that typifies reptiles, to that
Differential parental care behaviors of arboreal and terrestrial microhylid frogs from Papua New Guinea
Analysis of the ecology of parental care behaviors displayed by two closely related sympatric species of microhylid frogs in Papua New Guinea shows a significant positive effect of parental attendance on offspring survivorship and differential causes of egg mortality between microhabitats.
The influence of territoriality and mating system on the evolution of male care: a phylogenetic study on fish
It is argued that it is the combination of territoriality and pair spawning with sequential polygyny that favours the evolution of male care, and the results in relation to paternity assurance and sexual selection are discussed.
Predation and the evolution of complex oviposition behaviour in Amazon rainforest frogs
The strong negative relationship between the occurrence of fish and the egg predators suggests the surprising conclusion that the presence of fish actually protects aquatic anuran eggs from predation in this tropical system, and allows aquatic oviposition to dominate only in those waterbodies with moderate to high densities of fish.
Biology of Amphibians
This chapter discusses the origins and status of the lissamphibia cytogenetic, molecular and genomic evolution - cytogenetics, molecular evolution, genomic evolution phylogeny, and the evolutionary significance of metamorphosis.
The evolution of parental care and egg size: a comparative analysis in frogs
A phylogenetic supertree was developed by combining the results of multiple phylogenetic analyses in the literature using matrix representation parsimony and used recently developed maximum likelihood methods to infer the evolutionary order of specific transitions, revealing that the evolution of large egg size typically precedes the Evolution of parental care, rather than the reverse.
Tests of the mate-guarding hypothesis for social monogamy: male snapping shrimp prefer to associate with high-value females
Data suggest that males of A. angulatus engage in precopulatory mate-guarding behavior, and other factors (population density, sex ratio) may have played a role in the temporal extension of mate guarding to social monogamy.
