Recovery of insular seabird populations years after rodent eradication
Abstract Seabirds have been particularly affected by invasive non‐native species, which has led to the implementation of numerous eradication campaigns for the conservation of these keystone and highly vulnerable species. Although the benefits of eradication of invasive non‐native species for seabird conservation have been demonstrated, the recovery ...

Smaller species experience mild adversity under shading in an old‐field plant community
We characterized the light environment and tested for evidence of a size‐advantage in light competition in an old‐field plant community. We found that plots with taller species cast more shade, and that smaller species were less abundant and diverse in plots where light penetration was low; however, variation in mean plot height explained less than 10%

We use phylogenetic analysis to compare the effect of three different sequence clustering methods applied to long environmental rDNA amplicon sequences of soil microeukaryotic communities. We demonstrate that different clustering methods have a strong effect on estimated richness and identified taxa, but all methods recover large scale ecological ...

Abstract Coastal ecosystems are constantly buffeted by anthropogenic forces that degrade habitats and alter ecological processes and functions; in turn, this habitat degradation diminishes the ecosystem goods and services on which humans rely. Within the last few decades, the field of restoration ecology has burgeoned into a discipline that marries ...

Genomic analysis reveals deep population divergence in the water snake Trimerodytes percarinatus (Serpentes, Natricidae). [PDF]
In this work, we used both mtDNA data and SNP data to explore the population genetic structure, genetic diversity, and evolutionary history of a widespread, semiaquatic, non‐venomous snake Trimerodytes percarinatus. We hope our present study will be of wide interest to systematic researchers and phylogeographers.
