Amphibia, Anura, Odontophrynidae)
Neotropical Biology and Conservation 11(3):195-197, september-december 2016 Unisinos - doi: 10.4013/nbc.2016.113.10 SHORT COMMUNICATION Defensive behavior of Odontophrynus americanus (Duméril & Bibron, 1841) (Amphibia, Anura, Odontophrynidae) Comportamento defensivo de Odontophrynus americanus (Duméril & Bibron, 1841) (Amphibia, Anura, Odontophrynidae) Fábio Maffei1* [email protected] Abstract Anurans are a common prey of various animals and some species have developed de- Flávio Kulaif Ubaid2 [email protected] fense mechanisms against predators. One of these mechanisms is the stiff-legged, in which individuals change their posture to a flat body with stiff and stretched members. Here we report the first record of this behavior in Odontophrynus americanus, a small toad widespread in the southern portion of South America. We believe that this behavior aims to reduce the chances of being seen by the predator. Keywords: Brazil, Neotropical, frog, camouflage, defensive strategy, stiff-legged. Resumo Anuros são presas de diversos animais e algumas espécies desenvolveram mecanismos de defesa contra predadores. Um dos mecanismos de defesa é o stiff-legged, onde os indivíduos mudam sua postura ficando com o seu corpo achatado, membros rígidos e esticados. Aqui reportamos o primeiro registro desse comportamento em Odontophrynus americanus, um sapo de pequeno porte comum na porção sul da América do Sul. Acre- ditamos que esse comportamento tenha como objetivo reduzir as chances de ser visua- lizado pelo predador. Palavras-chave: Brasil, neotropical, sapo, camuflagem, estratégia defensiva. Anurans have an important role in the trophic chain, as a predator or prey of different species. They usually form aggregates during the rainy period, and can be found in great abundance throughout the breeding season. -

ABSTRACT Sixty specimens of Scinax fuscovarius (Lutz, 1925) were collected between May 2009 and October 2011 at Campo Belo do Sul, State of Santa Catarina, Brazil, and necropsied in search of helminth parasites. Only four helminth species were found: Pseudoacanthocephalus sp. Petrochenko, 1958, Cosmocerca brasiliense Travassos, 1925, C. parva Travassos, 1925 and Physaloptera sp. Rudolphi, 1819 (larvae). The genus of the female cosmocercids could not be determined. Only 30% of the anurans were parasitized. Scinax fuscovarius presented low prevalence, infection intensity, and parasite richness. Sex and size of S. fuscovarius individuals did not influence the prevalence, abundance, and species richness of helminth parasites. -

Reserve. 3 Costa Rica is internationally recognized as one of the most biologically diverse countries on the planet in total species numbers for many taxonomic groups of flora and fauna, one of those being amphibians. Costa Rica has 190 species of amphibians known from within its tiny 51,032 square kilometers territory. With 3.72 amphibian species per 1,000 sq. km. of national territory, Costa Rica is one of the richest countries in the world regarding amphibian diversity density. Amphibians are under constant threat by contamination, deforestation, climatic change, and disease. The majority of Costa Rica’s amphibians are surrounded by mystery in regards to their basic biology and roles in the ecology. Through intense research in the natural environment and in captivity many important aspects of their biology and conservation can become better known. The Costa Rican Amphibian Research Center (C.R.A.R.C.) was established in 2002, and is a privately owned and operated conservational and biological research center dedicated to studying, understanding, and conserving one of the most ecologically important animal groups of Neotropical humid forest ecosystems, that of the amphibians. -

Rua Purus, 33, 82520-750 Curitiba, PR, Brasil Manuscript received on September 17, 2014; accepted for publication on March 2, 2015 ABSTRACT Amphibian distribution patterns are known to be influenced by habitat diversity at breeding sites. Thus, breeding sites variability and how such variability influences anuran diversity is important. Here, we examine which characteristics at breeding sites are most influential on anuran diversity in grasslands associated with Araucaria forest, southern Brazil, especially in places at risk due to anthropic activities. We evaluate the associations between habitat heterogeneity and anuran species diversity in nine body of water from September 2008 to March 2010, in 12 field campaigns in which 16 species of anurans were found. Of the seven habitat descriptors we examined, water depth, pond surface area and distance to the nearest forest fragment explained 81% of total species diversity. -

Accepted September 20, 2007 We performed cytogenetic analyses on specimens from three population samples of Proceratophrys boiei from southeastern and northeastern Brazil. We stained chromosomes of mitotic and meiotic cells with Giemsa, C-banding and Ag-NOR methods. All specimens of P. boiei presented a karyotype with a full chromosome complement of 2n22, metacentric and submetacentric. We observed the secondary constriction within the short arm of pair 8, which was in the same position of the nucleolus organizer region (NOR). NOR heteromorphism was observed within two specimens from the municipality of Mata de Sa˜oJoa˜o (northeastern Bahia State). The C-banding evidenced an unusual heterochromatic pattern in the genome of P. boiei. In the southernmost population samples (Sa˜o Paulo State), we observed large blocks of heterochromatin in the centromeric regions of all chromosomes, whereas the northernmost samples (Bahia State) presented a small amount of constitutive heterochromatin. -

Hybrids of Amphibian Chytrid Show High Virulence in Native Hosts S

Haddad4 & C. G. Becker1 Received: 4 April 2018 Hybridization of parasites can generate new genotypes with high virulence. The fungal amphibian Accepted: 6 June 2018 parasite Batrachochytrium dendrobatidis (Bd) hybridizes in Brazil’s Atlantic Forest, a biodiversity Published: xx xx xxxx hotspot where amphibian declines have been linked to Bd, but the virulence of hybrid genotypes in native hosts has never been tested. We compared the virulence (measured as host mortality and infection burden) of hybrid Bd genotypes to the parental lineages, the putatively hypovirulent lineage Bd-Brazil and the hypervirulent Global Pandemic Lineage (Bd-GPL), in a panel of native Brazilian hosts. In Brachycephalus ephippium, the hybrid exceeded the virulence (host mortality) of both parents, suggesting that novelty arising from hybridization of Bd is a conservation concern. In Ischnocnema parva, host mortality in the hybrid treatment was intermediate between the parent treatments, suggesting that this species is more vulnerable to the aggressive phenotypes associated with Bd-GPL. Dendropsophus minutus showed low overall mortality, but infection burdens were higher in frogs treated with hybrid and Bd-GPL genotypes than with Bd-Brazil genotypes. Our experiment suggests that Bd hybrids have the potential to increase disease risk in native hosts. Continued surveillance is needed to track potential spread of hybrid genotypes and detect future genomic shifts in this dynamic disease system. Te host-parasite dynamic is a classic example of an evolutionary arms race; hosts face pressure to evolve defenses against parasites, while parasites face pressure to overcome host defenses1,2.
