The evidence of how organisms and populations are currently responding to climate change through phenotypic plasticity, genotypic evolution, changes in distribution and, in some cases, local extinction is reviewed.Abstract:
We review the evidence of how organisms and populations are currently responding to climate change through phenotypic plasticity, genotypic evolution, changes in distribution and, in some cases, local extinction. Organisms alter their gene expression and metabolism to increase the concentrations of several antistress compounds and to change their physiology, phenology, growth and reproduction in response to climate change. Rapid adaptation and microevolution occur at the population level. Together with these phenotypic and genotypic adaptations, the movement of organisms and the turnover of populations can lead to migration toward habitats with better conditions unless hindered by barriers. Both migration and local extinction of populations have occurred. However, many unknowns for all these processes remain. The roles of phenotypic plasticity and genotypic evolution and their possible trade-offs and links with population structure warrant further research. The application of omic techniques to ecological studies will greatly favor this research. It remains poorly understood how climate change will result in asymmetrical responses of species and how it will interact with other increasing global impacts, such as N eutrophication, changes in environmental N : P ratios and species invasion, among many others. The biogeochemical and biophysical feedbacks on climate of all these changes in vegetation are also poorly understood. We here review the evidence of responses to climate change and discuss the perspectives for increasing our knowledge of the interactions between climate change and life.read more

Drought-Induced Reduction in Global Terrestrial Net Primary Production from 2000 Through 2009
Maosheng Zhao,Steven W. Running +1 more
TL;DR: In this article, the authors suggest a reduction in the global NPP of 0.55 petagrams of carbon, which would not only weaken the terrestrial carbon sink, but would also intensify future competition between food demand and biofuel production.

Climate change and interconnected risks to sustainable development in the Mediterranean

TL;DR: In this paper, a dedicated effort to synthesize existing scientific knowledge across disciplines is underway and aims to provide a better understanding of the combined risks posed in the Mediterranean Basin, where fewer systematic observations schemes and impact models are based.

TL;DR: It is suggested that changes in aridity, such as those predicted by climate-change models, may reduce microbial abundance and diversity, a response that will likely impact the provision of key ecosystem services by global drylands.

Zavala,Jakob Zscheischler +26 more
TL;DR: It is found that ecosystem responses can exceed the duration of the climate impacts via lagged effects on the carbon cycle, and forests are expected to exhibit the largest net effect of extremes due to their large carbon pools and fluxes, potentially large indirect and lagged impacts, and long recovery time to regain previous stocks.

Transpiration modulates phosphorus acquisition in tropical tree seedlings
TL;DR: It is suggested that transpiration can influence the rate of P uptake from soil in tropical tree and liana seedlings through transport of inorganic phosphate and organic P compounds to root surfaces by transpiration-induced mass flow of the soil solution.

Ecological speciation without host plant specialization; possible origins of a recently described cryptic Papilio species
J. Mark Scriber,Gabriel Ording +1 more
TL;DR: It is hypothesized that strong selection against the facultative diapause (od‐)trait in regions with 2800 °F degree‐days or less, and divergent selection in favor of Pgd‐100 (or a closely linked trait) combined with allochronic reproductive isolation, has resulted in recombinational, parapatric, hybrid speciation.
