TL;DR: Using national crop and livestock production records and satellite-derived data on pasture greenness from 1982-2003, it is shown that the productivity of crops, livestock, and pastures in Africa is predictably associated with the El Niño Southern Oscillation and the North Atlantic Oscillations.

TL;DR: This is the first study to demonstrate that a consideration of both natural selection and artificial selection is needed to fully explain time-varying trait dynamics in harvested populations.

TL;DR: It is shown that the time of fruiting has changed considerably over this time period, with an average delay in fruiting since 1980 of 12.9 days, and early-fruiting species have experienced a stronger delay than late fruiters, resulting in a more compressed fruiting season.

TL;DR: In this paper, the authors explored the effect of climate on the recruitment of North Atlantic cod Gadus morhua, and concluded that cod recruitment is density-dependent, although the new analysis does not unequivocally support the existence of general pat- terns of densitydependent climate effects, possibly caused by demographic changes in the cod stocks (e.g. fishing-induced) and changes in biotic or abiotic environment (regime shifts).

TL;DR: It is demonstrated that climate conditions, through the effects of rainfall and temperature on mosquito abundance and dengue transmission rate, play key roles in explaining the temporal dynamics of d Dengue incidence in the human population.
