AbstractPopulation growth metrics such asR0are usually asymmetric functions of temperature, with cold-skewed curves arising when the positive effects of a temperature increase outweigh the negative effects, and warm-skewed curves arising in the opposite case. Classically, cold-skewed curves are interpreted as more beneficial to a species under climate warming, because cold-skewness implies increased population growth over a larger proportion of the species’ fundamental thermal niche than warm-skewness. However, inference based on the shape of the fitness curve alone, and without considering the synergistic effects of net reproduction, density, and dispersal may yield an incomplete understanding of climate change impacts. We formulate a moving-habitat integrodifference equation model to evaluate how fitness curve skewness affects species’ range size and abundance during climate warming. In contrast to classic interpretations, we find that climate warming adversely affects populations with cold-skewed fitness curves, positively affects populations with warm-skewed curves and has relatively little or mixed effects on populations with symmetric curves. Our results highlight the synergistic effects of fitness curve skewness, spatially heterogeneous densities, and dispersal in climate change impact analyses, and that the common approach of mapping changes only inR0may be misleading.

What explains variation in the tactical choices of non-governmental organizations (NGOs)? This article uses network autocorrelation models to establish how the tactical choices of climate change NGOs are shaped by their embeddedness in transnational advocacy networks. Specifically, it finds that NGOs are more likely to adopt protest tactics when adjacent organizations – those with whom they have direct ties – have already done so. The choices of equivalent organizations – those that occupy similar relational roles in the network – do not appear to be influential. Qualitative evidence also shows that NGOs are affected by relational pressure from their peers, which alters their perception of costs and benefits. These findings enhance understanding of how networks influence actors’ behavior and offer insights into the relational processes that generate protest in global politics.

Boreal Forest Birds

Many North American boreal forest birds reach the southern periphery of their distribution in the montane spruce–fir forests of northeastern United States and the barren coastal forests of Maritime Canada. Because the southern periphery may be the first to be impacted by warming climates, these populations provide a unique opportunity to examine several factors that will influence the conservation of this threatened group under climate change. We discuss recent research on boreal birds in Northeastern US and in Maritime Canada related to genetic diversity, population trends in abundance, distributional shifts in response to climate change, community composition, and threats from shifting nest predators. We discuss how results from these studies may inform the conservation of boreal birds in a warming world as well as open questions that need addressing.

Agriculture in the context of climate change is often a provocative subject because agriculture is both heavily impacted by the warming world and also a principal contributor to climate change. As efforts to reduce greenhouse gas emissions increase, the EU is pushing all sectors to integrate measures to combat climate change. This article argues that the agricultural sector has instigated a process of integrating climate concerns. However, these efforts will not lead to a large number of disruptive changes in the agricultural sector. While the EU is putting climate change firmly on the agricultural agenda, ranking the issue even higher than the environment, the Union’s primary goal is still to support the income of farmers. Hence, the EU’s intentions will likely lead to raising awareness of the issue of climate change in the context of agriculture but will not lead to any transformative changes in European agricultural policymaking.
