Microbial responses to warming enhance soil carbon loss following translocation across a tropical forest elevation gradient.

abstract：:What explains variation in the strength of sexual selection across species, populations or differences between the sexes? Here, we show that unifying two well-known lines of thinking provides the necessary conceptual framework to account for variation in sexual selection. The Bateman gradient and the operational sex r...
