Impacts Of Climate Change

Abstract This book is a collection of 77 expert opinions arranged in three sections. Section 1 on "Climate" sets the scene, including predictions of future climate change, how climate change affects ecosystems, and how to model projections of the spatial distribution of ticks and tick-borne infections under different climate change scenarios. Section 2 on "Ticks" focuses on ticks (although tick-borne pathogens creep in) and whether or not changes in climate affect the tick biosphere, from physiology to ecology. Section 3 on "Disease" focuses on the tick-host-pathogen biosphere, ranging from the triangle of tick-host-pathogen molecular interactions to disease ecology in various regions and ecosystems of the world. Each of these three sections ends with a synopsis that aims to give a brief overview of all the expert opinions within the section. The book concludes with Section 4 (Final Synopsis and Future Predictions). This synopsis attempts to summarize evidence provided by the experts of tangible impacts of climate change on ticks and tick-borne infections. In constructing their expert opinions, contributors give their views on what the future might hold. The final synopsis provides a snapshot of their expert thoughts on the future.

Radical Reduction

Climate change is a serious threat, and it is necessary to prepare for the future climate conditions of grazing areas. Dung beetle species can help mitigate global warming by contributing to intense nutrient cycling and reduction in greenhouse gas emissions caused by cattle farming. Additionally, dung beetles increase soil quality through bioturbation and reduce nematodes and hematophagous flies’ abundance in grasslands areas. There are several dung beetle species inhabiting South American pastures, however, the effects of climate change on their spatial distribution are still unknown. Here, we aimed to predict the potential effects of future climate change on the geographical spatial distribution of the four most important (“key”) pastureland dung beetle species that are native to South America. We used niche-based models and future climate simulations to predict species distribution through time. Our findings show radical reduction in the spatial range of dung beetle species, especially in recently opened areas, e.g., the Amazon region. We suggest that the consequences of these species’ spatial retraction will be correlated with ecosystem services depletion under future climate conditions, urgently necessitating pasture restoration and parasite control, as the introduction of new alien species is not encouraged.
