ACTN3 Allele Frequency in Humans Covaries with Global Latitudinal Gradient
A premature stop codon in ACTN3 resulting in α-actinin-3 deficiency (the ACTN3 577XX genotype) is common in humans and reduces strength, muscle mass, and fast-twitch fiber diameter, but increases the metabolic efficiency of skeletal muscle. Linkage disequilibrium data suggest that the ACTN3 R577X allele has undergone positive selection during human evolution. The allele has been hypothesized to...
متن کاملSoil organic nitrogen mineralization across a global latitudinal gradient
[1] Understanding and accurately predicting the fate of carbon and nitrogen in the terrestrial biosphere remains a central goal in ecosystem science. Amino acids represent a key pool of C and N in soil, and their availability to plants and microorganisms has been implicated as a major driver in regulating ecosystem functioning. Because of potential differences in biological diversity and litter...
متن کاملLatitudinal gradient in 2D:4D.
The potential dependence of second-to-fourth digit ratio (2D:4D) on latitude has been discussed in recent papers in this journal (Hurd & van Anders, 2007; Loehlin, McFadden, Medland, & Martin, 2006, 2007). Such an association was first suggested by Manning (2002), who proposed that 2D:4D was highest at intermediate latitudes and lowest at the equator and at high latitudes. In their Fig. 1, Hurd...
متن کاملLatitudinal gradient in species richness
What is the gradient? Amongst the earliest remarked, and best documented, of broad-scale spatial patterns of life on Earth is a trend for more species to be found towards lower latitudes. The latitudinal gradient in species richness is such that most extant eukaryote, perhaps also prokaryote, species are found in the tropics. Even when counted over quite small areas in which it is present, the ...
متن کاملA latitudinal phylogeographic diversity gradient in birds
High tropical species diversity is often attributed to evolutionary dynamics over long timescales. It is possible, however, that latitudinal variation in diversification begins when divergence occurs within species. Phylogeographic data capture this initial stage of diversification in which populations become geographically isolated and begin to differentiate genetically. There is limited under...
