Historical data reveal earlier flowering under environmental change

open access: yesNordic Journal of Botany, EarlyView.
Global temperatures have risen ~ 1.1°C since the 1800s and the mean annual air temperature in the Arctic has increased by nearly four times the global average. Temperature has a significant effect on fundamental life‐cycle events of flora and fauna. With temperatures increasing, Arctic plants are expected to shift their active periods accordingly, with

Aiouea riedeliana comb. nov. (Lauraceae) from Brazil, with an amended description and provisional extinction threat assessment

open access: yesNordic Journal of Botany, EarlyView.
Aiouea riedeliana (Kosterm.) P.L.R.Moraes and Brotto is the new combination for Cinnamomum riedelianum Kosterm., whose type‐bringing synonym is Persea riedelii Meisn. The placement of this taxon in Aiouea is presented, justified, and illustrated here, disagreeing with its previous classification in Ocotea, as Ocotea riedeliana (Kosterm.) Kottaim., then

Linking hierarchical assembly rules and diversity patterns of soil fungi in primary succession

open access: yesOikos, EarlyView.
Ecological succession affects natural communities in numerous ways, including deterministic (e.g. environmental filtering and biotic interactions) and stochastic processes (e.g. ecological drift and homogeneous dispersal). These processes may act across different spatial scales to set local communities, including environmental drivers characterizing ...
