Cím:	Multiple paternity is related to adult sex ratio and sex determination system in reptiles / Ivett Pipoly, Robert Duffy, Gábor Mészáros, Veronika Bókony, Balázs Vági, Tamás Székely, András Liker

Megjegyzések:	The adult sex ratio (ASR, the proportion of males in the adult population) is an emerging predictor of reproductive behaviour, and recent studies in birds and humans suggest it is a major driver of social mating systems and parental care. ASR may also influence genetic mating systems. For instance male-skewed ASRs are expected to increase the frequency of multiple paternity (defined here as a clutch or litter sired by two or more males) due to higher rates of coercive copulations by males, and/ or due to females exploiting the opportunity of copulation with multiple males to increase genetic diversity of their offspring. Here, we evaluate this hypothesis in reptiles that often exhibit high frequency of multiple paternity although its ecological and life-history predictors have remained controversial. Using a comprehensive dataset of 81 species representing all four non-avian reptile orders, we show tha increased frequency of multiple paternity is predicted by more male-skewed ASR, and this relationship is robust to simultaneous effects of several life-history predictors. Additionally, we show that the frequency of multiple paternity varies with the sex determination system: species with female heterogamety (ZZ/ZW sex chromosomes) exhibit higher levels of multiple paternity than species with male heterogamety (XY/XX) or temperature-dependent sex determination. Thus, our across species comparative study provides the first evidence that genetic mating system depends on ASR in reptiles. We call for further investigations to uncover the complex evolutionary associations between mating systems, sex determination systems and ASR.

Megjegyzések:	Complex parenting has been proposed to contribute to the evolutionary success of vertebrates. However, the evolutionary routes to complex parenting and the role of parenting in vertebrate diversity are still contentious. Although basal vertebrates provide clues to complex reproduction, these are often understudied. Using 181 species that represent all major lineages of an early vertebrate group, the salamanders and newts (Caudata, salamanders henceforth) here we show that fertilisation mode is tied to parental care: male-only care occurs in external fertilisers, whereas femaleonly care exclusively occurs in internal fertilisers. Importantly, internal fertilisation opens the way to terrestrial reproduction, because fertilised females are able to deposit their eggs on land, and with maternal care provision, the eggs could potentially develop outside the aquatic environment. Taken together, our results of a semi-aquatic early vertebrate group propose that the diversity and follow-up radiation of terrestrial vertebrates are inherently associated with a complex social behaviour, parenting.

Cím:	Parental care and the evolution of terrestriality in frogs / Balázs Vági, Zsolt Vegvári, András Liker, Robert P. Freckleton, Tamás Székely
Dátum:	2019

Megjegyzések:	Frogs and toads (Anura) exhibit some of the most diverse parental strategiesin vertebrates. Identifying the evolutionary origins of parenting is funda-mental to understanding the relationships between sexual selection, socialevolution and parental care systems of contemporary Anura. Moreover, par-enting has been hypothesized to allow the invasion of terrestrial habitats bythe ancestors of terrestrial vertebrates. Using comprehensive phylogeneticanalyses of frogs and toads based on data from over 1000 species that rep-resent 46 out of 55 Anura families, we test whether parental care isassociated with terrestrial reproduction and several life-history traits. Here,we show that both the duration of care and offspring protection by malesand females have coevolved with terrestrial reproduction. Sexual sizedimorphism is also related to care, because the large male size relative tofemale size is associated with increased paternal care. Furthermore,increased egg size and reduced clutch volume are associated with increasedcare in bivariate but not in multivariate analyses, suggesting that therelationships between care, egg size and clutch volume are mediated by ter-restrial reproduction. Taken together, our results suggest that parenting bymales and females has coevolved, and complex parenting traits haveevolved several times independently in Anura in response to breeding in ter-restrial environments.
