Abstract Toxoplasmosis is a parasitic disease, which is prevalent across the world and has a strong environmental component in its transmission chain. The present study determined the seroprevalence and factors related to Toxoplasma gondii infection among free-range chickens from an Atlantic Forest area ...

Abstract Haemoproteus spp. are protozoan parasites found in birds around the world. These parasites are identified through the morphology of gametocytes, phylogenetic analysis based on the mitochondrial cytb gene, and the parasite's geographic distribution. The absence of erythrocytic merogony, high intr...

Abstract The objective of this study was to investigate the frequency of antibodies to Toxoplasma gondii present in wild mammals that were trap captured in forest fragments in the State of Bahia, northeastern Brazil. A total of 368 individuals (246 rodents, 104 marsupials and 18 bats) were captured using...
Abstract INTRODUCTION: Haemagogus are mosquitoes with diurnal habits that live preferentially in forest areas. In Brazil, they are considered the primary vectors of wild yellow fever. METHODS: The ecological relationships between Haemagogus spegazzinii, the environment, and some of its activities in th...
BACKGROUND Southeast Brazil has recently experienced a Yellow Fever virus (YFV) outbreak where the mosquito Haemagogus leucocelaenus was a primary vector. Climatic factors influence the abundance of mosquito vectors and arbovirus transmission. OBJECTIVES We aimed at describing the population dynamics ...

Abstract To accelerate the recovery of degraded environments, it is necessary to use ecological restoration techniques, which require validation according to the ecosystem conditions where are implemented. This work aimed to evaluate soil microbiological attributes under different ecological restoration ...
BACKGROUND Deforestation, driven by anthropogenic change in land use, influences the behaviour and abundance of vector-borne diseases. For various species of Chagas disease vectors, there is evidence that change in land use affects population density and abundance. Triatoma dimidiata is the most importa...
Resumo O contexto da pandemia da Covid-19 está relacionado à interação dos seres humanos com a natureza, na medida em que invadimos e destruímos nichos ecológicos importantes, criando modelos de produção animal e de trocas comerciais não sustentáveis. Lavar as mãos é uma das ações mais efic...
Introduction: Estimating aboveground biomass (AGB) in protected forests is a challenge, due to high costs and legal restrictions for direct assessments, and also to frequently weak estimation provided by general AGB equations. Objective: We propose a new approach that uses dead fallen trees (DFTs) to imp...
Introducción: Los colémbolos epiedáficos participan en una amplia variedad de servicios ecosistémicos relacionados con la disponibilidad de nutrientes para las plantas, el almacenamiento y la regulación del agua, la estabilidad del suelo y el control de la humedad y el pH necesarios para la fertilid...
