Changing Patterns of Emerging Zoonotic Diseases in Wildlife, Domestic Animals, and Humans Linked to Biodiversity Loss and Globalization.

Abstract

The fundamental human threats to biodiversity including habitat destruction, globalization, and species loss have led to ecosystem disruptions altering infectious disease transmission patterns, the accumulation of toxic pollutants, and the invasion of alien species and pathogens. To top it all, the profound role of climate change on many ecological processes has affected the inability of many species to adapt to these relatively rapid changes. This special issue, "Zoonotic Disease Ecology: Effects on Humans, Domestic Animals and Wildlife," explores the complex interactions of emerging infectious diseases across taxa linked to many of these anthropogenic and environmental drivers. Selected emerging zoonoses including RNA viruses, Rift Valley fever, trypanosomiasis, Hanta virus infection, and other vector-borne diseases are discussed in detail. Also, coprophagous beetles are proposed as important vectors in the transmission and maintenance of infectious pathogens. An overview of the impacts of climate change in emerging disease ecology within the context of Brazil as a case study is provided. Animal Care and Use Committee requirements were investigated, concluding that ecology journals have low rates of explicit statements regarding the welfare and wellbing of wildlife during experimental studies. Most of the solutions to protect biodiversity and predicting and preventing the next epidemic in humans originating from wildlife are oriented towards the developed world and are less useful for biodiverse, low-income economies. We need the development of regional policies to address these issues at the local level.
