Biodiversity of Coreoidea and Pentatomidae (Heteroptera) from Atlantic forest protected areas. Insights into their conservation

An. acad. bras. ciênc; 90 (1), 2018
ABSTRACT Although the majority of threatened species are likely to be tropical insects, knowledge of the diversity, ecological role and impact of insect biodiversity loss on ecosystem processes is very limited. Specimens belonging to four families of Heteroptera: Pentatomidae, Coreidae, Alydidae and Rhop...

Bird diversity along a gradient of fragmented habitats of the Cerrado

An. acad. bras. ciênc; 90 (1), 2018
ABSTRACT Understanding the factors that affect biodiversity is of central interest to ecology, and essential to species conservation and ecosystems management.

Leptospira inadai is classified as a species of the Leptospira intermediate group that has been poorly studied due to its apparent insignificance to human and animal health. Nevertheless, over the last two decades the species has been described in human cases in India and in carrier animals in Ecuador. H...

Study of Microbial Interaction Formed by "Candida krusei" and "Candida glabrata": "In Vitro" and "In Vivo" Studies

Braz. dent. j; 28 (6), 2017
Abstract Recently, the non-albicans Candida species have become recognized as an important source of infection and oral colonization by association of different species in a large number of immunosuppressed patients. The objective of this study was to evaluate the interactions between C. krusei and C. gl...
