Direct and indirect effects of environmental factors, spatial constraints, and functional traits on shaping the plant diversity of montane forests

open access: yesEcology and Evolution, 2020
Understanding the relative importance of the factors driving the patterns of biodiversity is a key research topic in community ecology and biogeography. However, the main drivers of plant species diversity in montane forests are still not clear.

Emerging experimental and computational methods for studying redox‐regulated structural transitions

open access: yesFEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Dynamics of Invertebrate Diversity in a Tropical Stream

open access: yesDiversity, 2014
Regional studies of biotic communities are important for characterising their normal spatial and temporal variation, but there are few such studies of tropical streams.

RNA‐related functions of BRCA2 in transcription, replication, and genome stability

open access: yesFEBS Letters, EarlyView.
Beyond its role in homologous recombination, BRCA2 regulates R‐loop homeostasis, DNA–RNA hybrid resolution, RNA polymerase II dynamics, and transcriptional activation. Disruption of any of these functions can contribute to genome instability, inflammatory signaling, and tumorigenesis. BRCA2 is a central tumor suppressor protein best known for its roles

Jackknife Estimator of Species Richness with S-PLUS [PDF]

open access: yes
An estimate of the number of species, S , usually called species richness by ecologists, in an area is one of the basic statistics used to ascertain biological diversity. Traditionally ecologists have used the number of species observed in a sample, S_0 ,

Re-structuring of marine communities exposed to environmental change [PDF]

open access: yes, 2011
Species richness is the most commonly used but controversial biodiversity metric in studies on aspects of community stability such as structural composition or productivity.

Breeding bird communities in a morain landscape (Affi, North-Western Venetia): a preliminary survey.

open access: yesRivista Italiana di Ornitologia - Research in Ornithology, 2012
A pilot study was conducted on a moraine hilly landscape (Affi, Verona). We found 43 species of birds overall (40 breeding, two migrants, one exotic species).

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

open access: yesFEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.

SPECIES: An R Package for Species Richness Estimation [PDF]

open access: yes
We introduce an R package SPECIES for species richness or diversity estimation. This package provides simple R functions to compute point and confidence interval estimates of species number from a few nonparametric and semi-parametric methods.

A new model to describe the relationship between species richness and sample size [PDF]

open access: yes, 2017
In the sampling of species richness, the number of newly found species declines as increase of sample size, and the number of distinct species tends to an upper asymptote as sample size tends to the infinity. This leads to a curve of species richness vs.
