Ecological Networks are more Sensitive to Plant than to Animal Extinction under Climate Change

by Leta Ames

There is a growing need for climate change models that can accurately represent not only the effects on individual species, but also the interactions and compounding effects within ecosystems. These interactions between species form different “mutualistic networks”. Schleuning et al. (2016) modeled the impact of individual species’ responses to climate change in plant-animal mutualistic networks. Specifically, climatic tolerance of 295 plant species, in eight pollinator networks and five seed-disperser networks in unique areas of central Europe were used to understand the relationship between sensitivity to climate change, climatic niche breadth, and biotic specializations.

Tracking Vulnerabilities to the Risks of Infectious Disease Transmission due to Climate Change in Europe

by Amelia Hamiter

Suk et al. (2014) examine vulnerability as a measurement of both the impact of climate change on infections disease transmission in a region and the region’s ability to respond (described here as adaptive capacity). This concept of vulnerability differs from that used in most public health practices, which generally do not take adaptive capacity as a component of vulnerability. Indeed, the authors note that the health sector has produced little research that examines infectious disease transmission due to climate change or the effects of different socioeconomic development pathways in studies of vulnerability. Thus, they take on the task of creating a quantitative indicator to measure regional vulnerabilities that combines all of these factors. Their projections assess which regions are projected to undergo climate changes more significant than their adaptive capacities, and thus are particularly vulnerable. They evaluate that some of these high vulnerabilities are driven by low adaptive capacities, while others have high adaptive capacities yet face enough projected climate change that they are still highly vulnerable. The researchers recommend that the next steps forward are to carry out more disease-specific and more detailed health indicators of vulnerability studies. Continue reading
