Atualidades no tratamento da laminite em equinos

Laminitis is still a major cause of lameness in horses, causing damage to many interested in it. It has been long studied, but there are several points that are not yet fully understood. Doubts about its pathogenesis end up extending at the treatments. Just as there are several theories that attempt to explain the mechanisms of its development, also appear treatments that are sometimes contradictory and inconsistent. Mostly times, laminitis is a consequence of another disease process that occurs systemically in the body. Among them are the main grain overload and processes that cause the animal to the table of endotoxemia, strangled colic, metritis with retained placenta and pleuropneumonia. The proposed treatments include the use of anti-inflammatory drugs, cryotherapy, use of vasodilators and correction of Starling forces, and other measures to support the frog. The stall should be bedded deeply with sand or other material that provides support to the frog

O estado da arte das vocalizações de anfíbios anuros da Mata Atlântica

The vocals are the most conspicuous means of communication between frogs and can express evolutionary relationships among species. Call descriptions of frogs, in general, not standard acoustic parameters which are greatly diversified and usually restricted to comparisons between closely related taxa. The Atlantic Forest is considered one of the biodiversity hotspots of the world, however, it appears that the number of species to be known is still very large. To anurans from this Brazilian Domain, vocalizations are complex and can vary intra and interpopulations. Thus, we presented a quantitative and qualitative analysis of the work descriptions of anuran advertisement call from the Atlantic Forest, available in the literature so far. The frog species from this Domain and their descriptions of the advertisement call have been raised in the literature, organized into families and threat category IUCN Red List Threatened Species. The analysis of the descriptions were made based on the presence of preset parameters. It was observed that the species which the advertisement call is described within the standard are expected within the Brazilian Atlantic Domain, but efforts to describe the advertisement call of frogs of the Atlantic are concentrated in non-threatened species. Among the descriptions works, there is a large discrepancy between the information presented, giving preference to the use of abiotic data in this kind of work, to the detriment of biotic data about choir where the songs were recorded. The results point to the need for advancements in the descriptions of the advertisement of endangered species or to those with deficient information on their conservation status in the Atlantic Forest, and also for greater communication between works that describe vocalizations of frogs. It will be important to know about the state of the art of descriptions works of frogs in other Brazilian Domains, and relate this information with knowledge...

Linking genetic and environmental factors in amphibian disease risk

A central question in evolutionary biology is how interactions between organisms and the environment shape genetic differentiation. The pathogen Batrachochytrium dendrobatidis (Bd) has caused variable population declines in the lowland leopard frog (Lithobates yavapaiensis); thus, disease has potentially shaped, or been shaped by, host genetic diversity. Environmental factors can also influence both amphibian immunity and Bd virulence, confounding our ability to assess the genetic effects on disease dynamics. Here, we used genetics, pathogen dynamics, and environmental data to characterize L.yavapaiensis populations, estimate migration, and determine relative contributions of genetic and environmental factors in predicting Bd dynamics. We found that the two uninfected populations belonged to a single genetic deme, whereas each infected population was genetically unique. We detected an outlier locus that deviated from neutral expectations and was significantly correlated with mortality within populations. Across populations, only environmental variables predicted infection intensity, whereas environment and genetics predicted infection prevalence, and genetic diversity alone predicted mortality. At one locality with geothermally elevated water temperatures, migration estimates revealed source-sink dynamics that have likely prevented local adaptation. We conclude that integrating genetic and environmental variation among populations provides a better understanding of Bd spatial epidemiology, generating more effective conservation management strategies for mitigating amphibian declines.
