Polyploidy and Sex Chromosome Evolution in Amphibians
Chapter 18 Polyploidization and Sex Chromosome Evolution in Amphibians Ben J. Evans, R. Alexander Pyron and John J. Wiens Abstract Genome duplication, including polyploid speciation and spontaneous polyploidy in diploid species, occurs more frequently in amphibians than mammals. One possible explanation is that some amphibians, unlike almost all mammals, have young sex chromosomes that carry a similar suite of genes (apart from the genetic trigger for sex determination). These species potentially can experience genome duplication without disrupting dosage stoichiometry between interacting proteins encoded by genes on the sex chromosomes and autosomalPROOF chromosomes. To explore this possibility, we performed a permutation aimed at testing whether amphibian species that experienced polyploid speciation or spontaneous polyploidy have younger sex chromosomes than other amphibians. While the most conservative permutation was not significant, the frog genera Xenopus and Leiopelma provide anecdotal support for a negative correlation between the age of sex chromosomes and a species’ propensity to undergo genome duplication. This study also points to more frequent turnover of sex chromosomes than previously proposed, and suggests a lack of statistical support for male versus female heterogamy in the most recent common ancestors of frogs, salamanders, and amphibians in general. Future advances in genomics undoubtedly will further illuminate the relationship between amphibian sex chromosome degeneration and genome duplication. B. J.

Ecological Functions of Neotropical Amphibians and Reptiles: a Review
Univ. Sci. 2015, Vol. 20 (2): 229-245 doi: 10.11144/Javeriana.SC20-2.efna Freely available on line REVIEW ARTICLE Ecological functions of neotropical amphibians and reptiles: a review Cortés-Gomez AM1, Ruiz-Agudelo CA2 , Valencia-Aguilar A3, Ladle RJ4 Abstract Amphibians and reptiles (herps) are the most abundant and diverse vertebrate taxa in tropical ecosystems. Nevertheless, little is known about their role in maintaining and regulating ecosystem functions and, by extension, their potential value for supporting ecosystem services. Here, we review research on the ecological functions of Neotropical herps, in different sources (the bibliographic databases, book chapters, etc.). A total of 167 Neotropical herpetology studies published over the last four decades (1970 to 2014) were reviewed, providing information on more than 100 species that contribute to at least five categories of ecological functions: i) nutrient cycling; ii) bioturbation; iii) pollination; iv) seed dispersal, and; v) energy flow through ecosystems. We emphasize the need to expand the knowledge about ecological functions in Neotropical ecosystems and the mechanisms behind these, through the study of functional traits and analysis of ecological processes. Many of these functions provide key ecosystem services, such as biological pest control, seed dispersal and water quality. By knowing and understanding the functions that perform the herps in ecosystems, management plans for cultural landscapes, restoration or recovery projects of landscapes that involve aquatic and terrestrial systems, development of comprehensive plans and detailed conservation of species and ecosystems may be structured in a more appropriate way. Besides information gaps identified in this review, this contribution explores these issues in terms of better understanding of key questions in the study of ecosystem services and biodiversity and, also, of how these services are generated. -

Mating Patterns and Post-Mating Isolation in Three Cryptic Species of the Engystomops Petersi Species Complex Abstract Determining the extent of reproductive isolation in cryptic species with dynamic geographic ranges can yield important insights into the processes that generate and maintain genetic divergence in the absence of severe geographic barriers. We studied mating patterns, propensity to hybridize in nature and subsequent fertilization rates, as well as survival and development of hybrid F1 offspring for three nominal species of the Engystomops petersi species complex in Yasuní National Park, Ecuador. -

Breeding Biology of Neotropical Accipitriformes: Current Knowledge and Research Priorities
Revista Brasileira de Ornitologia 26(2): 151–186. ARTICLE June 2018 Breeding biology of Neotropical Accipitriformes: current knowledge and research priorities Julio Amaro Betto Monsalvo1,3, Neander Marcel Heming2 & Miguel Ângelo Marini2 1 Programa de Pós-graduação em Ecologia, IB, Universidade de Brasília, Brasília, DF, Brazil. 2 Departamento de Zoologia, IB, Universidade de Brasília, Brasília, DF, Brazil. 3 Corresponding author: [email protected] Received on 08 March 2018. Accepted on 20 July 2018. ABSTRACT: Despite the key role that knowledge on breeding biology of Accipitriformes plays in their management and conservation, survey of the state-of-the-art and of information gaps spanning the entire Neotropics has not been done since 1995. We provide an updated classification of current knowledge about breeding biology of Neotropical Accipitridae and define the taxa that should be prioritized by future studies. We analyzed 440 publications produced since 1995 that reported breeding of 56 species. There is a persistent scarcity, or complete absence, of information about the nests of eight species, and about breeding behavior of another ten. Among these species, the largest gap of breeding data refers to the former “Leucopternis” hawks. Although 66% of the 56 evaluated species had some improvement on knowledge about their breeding traits, research still focus disproportionately on a few regions and species, and the scarcity of breeding data on many South American Accipitridae persists. We noted that analysis of records from both a citizen science digital database and museum egg collections significantly increased breeding information on some species, relative to recent literature. We created four groups of priority species for breeding biology studies, based on knowledge gaps and threat categories at global level.
