Metabarcoding the Antarctic Peninsula biodiversity using a multi-gene approach

Benthic Megafaunal Community Structure and Biodiversity Along a Sea Ice Gradient on the Western Antarctic Peninsula:

The Western Antarctic Peninsula (WAP) is experiencing some of the fastest rates of regional warming in the world, resulting in the collapse of ice shelves, warming ocean temperatures, and increased melt and retreat of glaciers. Winter sea ice coverage in the waters off the WAP has decreased in duration and extent over the last half century. The significant changes observed off the WAP are extre...

Leg 178 Antarctic Peninsula

Leg 178 will drill eight sites off the Pacific margin of the Antarctic Peninsula to provide a highresolution record of Antarctic continental climate over the past 6-10 m.y. and a direct check on the presumed glacio-eustatic origin of global sea-level change over the same period. Moreover, it is an essential preliminary to the more difficult task of extracting the complete Cenozoic record of Ant...

Next-generation monitoring of aquatic biodiversity using environmental DNA metabarcoding.

Global biodiversity in freshwater and the oceans is declining at high rates. Reliable tools for assessing and monitoring aquatic biodiversity, especially for rare and secretive species, are important for efficient and timely management. Recent advances in DNA sequencing have provided a new tool for species detection from DNA present in the environment. In this study, we tested whether an enviro...

Marine pelagic ecosystems: the west Antarctic Peninsula.

The marine ecosystem of the West Antarctic Peninsula (WAP) extends from the Bellingshausen Sea to the northern tip of the peninsula and from the mostly glaciated coast across the continental shelf to the shelf break in the west. The glacially sculpted coastline along the peninsula is highly convoluted and characterized by deep embayments that are often interconnected by channels that facilitate...
