A Pilot Investigation of the Hidden Communities Associated With Dryas octopetala L. (Rosaceae) in Svalbard Using DNA Metabarcoding. [PDF]

open access: yesEnviron Microbiol Rep
A single marker revealed a considerable diversity of organisms associate with Dryas octopetala. The rhizosphere contains more taxa than the phyllosphere. Some taxa are cited for the first time in the Svalbard Archipelago. The use of different DNA marker will increase diversity data in the Svalbard Archipelago.

Habitat-Based Predictions of Bridle Shiner (<i>Notropis bifrenatus</i>) in the Northeastern United States. [PDF]

open access: yesEcol Evol
We developed local and regional models for Maine and New Hampshire that may be used to focus bridle shiner (Notropis bifrenatus) surveys on areas with high predicted habitat suitability. This is significant because bridle shiners receive protection or concern status in thirteen states and two Canadian provinces: Limited data show that bridle shiners ...
