pH-sensitivity in boreal streams – the influence of landscape characteristics por Isaksson, Linda

“…In the northern subcatchments, pH-sensitivity was positively correlated to water surfaces and coarse quaternary deposits with Scots pine forests. In the south, pH-sensitive streams were positively correlated to till soils and the concentrations of total organic matter (TOC). …”

Population genomics of the widespread African savannah trees Afzelia africana and Afzelia quanzensis reveals no significant past fragmentation of their distribution ranges por Donkpegan, A.S.L., Piñeiro, R., Heuertz, M., Duminil, J., Daïnou, K., Doucet, J.-L., Hardy, Olivier J.

“…We aimed to infer whether these species underwent range fragmentation and/or demographic changes, possibly reflecting how savannahs responded to Quaternary climate changes. We characterized the genetic diversity and structure of these species across their distribution ranges using nuclear microsatellites (SSRs) and genotyping‐by‐sequencing (GBS) markers. …”
