Cyanobacterial blooms have substantial direct and indirect negative impacts on freshwater
ecosystems including releasing toxins, blocking light needed by other organisms, and …

BRCA1 is a large multi-domain protein with a pivotal role in maintaining genome stability
and cell cycle progression. Germline mutations in the BRCA1 gene confer an estimated …

Perennially cold habitats are diminishing as a result of climate change; however, little is
known of the diversity or biogeography of microbes that thrive in such environments. Here …

Lake Untersee is one of the largest (11.4 km2) and deepest (> 160 m) freshwater lakes in
East Antarctica. Located at 71° S the lake has a perennial ice cover, a water column that …

Clues to the evolutionary steps producing innovations in oxygenic photosynthesis may be
preserved in the genomes of organisms phylogenetically placed between non …

Lake Fryxell is a perennially ice-covered lake in the McMurdo Dry Valleys, Antarctica, with a
sharp oxycline in a water column that is density stabilized by a gradient in salt concentration …

Cyanobacteria are commonly thought of as microbial phototrophs that are characteristic of
warm water environments such as hot springs (Steunou et al., 2006), stratified lakes during …

Perennially cold environments in which temperatures remain below 5° C are common
throughout the biosphere (Margesin and Häggblom 2007). In these habitats, the persistent …

By way of metagenomics and high‐throughput pyrosequencing, we addressed the
hypothesis that cyanobacterial mats in polar aquatic ecosystems maintain a nutrient‐rich …

This study measured the primary productivity (PP eu) of phytoplankton in Wuliangsuhai Lake
from April 2014 to January 2019 based on the monitoring and on-site exploration of 20 …
