Thermal acclimation of leaf respiration consistent with optimal plant function

Main Main References Introduction Terrestrial plant respiration is a major component of the global carbon cycle, releasing ca. 60 Pg C yr-1 to the atmosphere: six times more than anthropogenic CO2 emissions from all sources combined (Ciais et al. 2014). About half this flux is leaf maintenance respiration in darkness (Rd) (Atkin et al. 2007). Rd is highly temperature-dependent, following a near-exponential relationship over short time-scales (Heskel et al. 2016). It has been predicted that global warming will increase Rd and accelerate future climate change via a carbon-climate feedback (Cox et al. 2000; Huntingford et al. 2013). However, large uncertainties in future ...

Natural diversity of the malaria vector Anopheles gambiae

The sustainability of malaria control in Africa is threatened by rising levels of insecticide resistance, and new tools to prevent malaria transmission are urgently needed. To gain a better understanding of the mosquito populations that transmit malaria, we sequenced the genomes of 765 wild specimens of Anopheles gambiae and Anopheles coluzzii sampled from 15 locations across Africa. The data reveal high levels of genetic diversity, with over 50 million single nucleotide polymorphisms across the 230 Mbp genome. We observe complex patterns of population structure and marked variations in local population size, some of which may be due at least in part to malaria control interventions. Insecticide resistance genes show strong signatures of recent selection associated with multiple independent mutations spreading over large geographical distances and between species. The genetic variability of natural populations substantially reduces the target space for novel gene-drive strategies for mosquito control. This large dataset provides a foundation for tracking the emergence and spread of insecticide resistance and developing new vector control tools.
