A recent collection of from the Dominican Republic is presented here. Macro- and micromorphological features of are described in detail, and its evolutionary (phylogenetic) position within sect. , in the subincarnata/brunneoincarnata clade, is assessed on the basis of a combined nrLSU + nrITS + + analysis. Additionally, high levels of deadly amatoxins were detected and quantified in for the first time by HPLC analysis; in particular, α-amanitin was found at concentrations up to approximately 4 mg/g dry weight, which render a potentially lethal mushroom, if ingested.

Anatomical knowledge is fundamental for all species. In particular, myology allows a deeper understanding of ecomorphology-especially for those species hard to observe in the wild-and may be an important source for phylogenetic information. In this study, we analyzed the myological variation of the musculature of the shoulder and arm of the forelimb in species of the suborder Feliformia and its relationship with the phylogenetic history and the locomotor behavior, habitat, and predatory habits of the species within this group, using Leopardus geoffroyi as a case study.

Yellow fever (YF) is a viral disease that affects both humans and non-human primates (NHPs). Neotropical monkeys are more severely stricken by YF and the impact of the disease can be devastating to the endangered golden-headed lion tamarins (GHLTs, Leontopithecus chrysomelas). Susceptible GHLTs were immunized with the commercial Brazilian YF 17DD live attenuated vaccine or two other experimental non-replicating YF vaccines: a purified whole-virus, b-propiolactone-inactivated vaccine and a plant-derived recombinant subunit vaccine.

Phenanthrene is considered a priority polycyclic aromatic hydrocarbon due to its ubiquitous presence in aquatic and terrestrial environments and its toxic potential. Tadpoles are sensitive ecotoxicological models that provide important information regarding effects of contaminants in amphibian species. The goal of the present study was to generate information regarding the acute and chronic toxicity of phenanthrene to the neotropical tree frog Dendropsophus branneri early life stages.
