The species concept is the cornerstone of biodiversity science, and any paradigm shift in the
delimitation of species affects many research fields. Many biologists now are embracing a …

The deep sea, the largest biome on Earth, has a series of characteristics that make this
environment both distinct from other marine and land ecosystems and unique for the entire …

Millions of metric tons of plastics are produced annually and transported from land to the
oceans. Finding the fate of the plastic debris will help define the impacts of plastic pollution …

The threat posed by plastic pollution to marine ecosystems and human health is under
increasing scrutiny. Much of the macro-and microplastic in the ocean ends up on the …

Plastic debris and marine microplastics are being discharged into the ocean at an alarming
scale and have been observed throughout the marine environment. Here we report …

The legacy and reach of anthropogenic influence is most clearly evidenced by its impact on
the most remote and inaccessible habitats on Earth. Here we identify extraordinary levels of …

Hadal trenches are the deepest and most remote regions of the ocean. The 11-kilometer
deep Challenger Deep is the least explored due to the technical challenges of sampling …

Covering about three quarters of the surface area of the earth, the ocean is a critical source
of sustenance, medicine, and commerce. However, such vast expanse in both surface area …

Hadal oceans at water depths below 6,000 m are the least-explored aquatic biosphere. The
Challenger Deep, located in the western equatorial Pacific, with a water depth of∼ 11 km, is …

While there are many generalized schemes representing the biogeographic distribution of
life in the deep sea, reviewed here, a comprehensive analysis has not been undertaken …
