TLDR
It is argued that studies examining the ecological and evolutionary impacts of climate change should consider the 'thermal fertility limit' (TFL) of species; and a framework for the design of TFL studies across taxa be developed.Abstract:
Rising global temperatures are threatening biodiversity. Studies on the impact of temperature on natural populations usually use lethal or viability thresholds, termed the ‘critical thermal limit’ (CTL). However, this overlooks important sublethal impacts of temperature that could affect species’ persistence. Here we discuss a critical but overlooked trait: fertility, which can deteriorate at temperatures less severe than an organism’s lethal limit. We argue that studies examining the ecological and evolutionary impacts of climate change should consider the ‘thermal fertility limit’ (TFL) of species; we propose that a framework for the design of TFL studies across taxa be developed. Given the importance of fertility for population persistence, understanding how climate change affects TFLs is vital for the assessment of future biodiversity impacts.read more

TL;DR: Analysis of stage-specific thermal tolerance metrics for 694 marine and freshwater fish species shows that spawning adults and embryos consistently have narrower tolerance ranges than larvae and nonreproductive adults and are most vulnerable to climate warming.

The Impact of Population Growth on Natural Resources and Farmers’ Capacity to Adapt to Climate Change in Low-Income Countries
TL;DR: In this article, the authors reviewed publications on low-income countries with emphasis on sub-Saharan Africa and Southeast Asia to reveal the impacts of population growth on natural resources and uncover farmers' capacity to adapt to climate change in low income countries.

Climate change‐mediated temperature extremes and insects: From outbreaks to breakdowns
TL;DR: It is argued that TE can push insect herbivores and their natural enemies to and even beyond their adaptive limits, which may differ among species intimately involved in trophic interactions, leading to phenological disruptions and the structural reorganization of food webs.

Predicting temperature mortality and selection in natural Drosophila populations.
TL;DR: The model quantifies temperature-induced mortality in nature, which is crucial to study the effects of global warming on natural populations, and analyses highlight that critical temperatures are unreliable predictors of mortality.

TL;DR: The results show that warming in the tropics, although relatively small in magnitude, is likely to have the most deleterious consequences because tropical insects are relatively sensitive to temperature change and are currently living very close to their optimal temperature, so that warming may even enhance their fitness.

TL;DR: The way the Drosophila research has been used to understand the evolution of plastic responses, tradeoffs and limits to selection, and to develop links between laboratory studies and adaptive shifts leading to population and species differences is examined.

The Future of Species Under Climate Change: Resilience or Decline?
TL;DR: The fossil record suggests that most species persisted through past climate change, whereas forecasts of future impacts predict large-scale range reduction and extinction, but responses are highly variable.
