High functional diversity is related to high nitrogen availability in a deciduous forest - evidence from a functional trait approach [PDF]

open access: yes, 2010
The current study tested the assumption that floristic and functional diversity patterns are negatively related to soil nitrogen content. We analyzed 20 plots with soil N-contents ranging from 0.63% to 1.06% in a deciduous forest near Munich (Germany ...

Differential temporal beta‐diversity patterns of native and non‐native arthropod species in a fragmented native forest landscape [PDF]

open access: yes, 2018
An important factor that hinders the management of non‐native species is a general lack of information regarding the biogeography of non‐natives, and, in particular, their rates of turnover.

Chloroplast phylogenomic analysis provides insights into the evolution of the largest eukaryotic genome holder, Paris japonica (Melanthiaceae)

open access: yesBMC Plant Biology, 2019
Background Robust phylogenies for species with giant genomes and closely related taxa can build evolutionary frameworks for investigating the origin and evolution of these genomic gigantisms. Paris japonica (Melanthiaceae) has the largest genome that has

Stand structural diversity rather than species diversity enhancesaboveground carbon storage in secondary subtropical forests in Eastern China

open access: yes, 2016
. Stand structural diversity, typically characterized by variances in tree diameter at breast height (DBH) and total height, plays a critical role in influencing aboveground carbon (C) storage.
