Researchers from the Institute of Deep-sea Science and Engineering (IDSSE) of the Chinese Academy of Sciences, in collaboration with the University of Pisa, Italy, and the National Institute of Water and Atmosphere Research, New Zealand, have now documented the world’s deepest and largest known aggregation of whale fossils and active whale-fall ecosystems. This deep-sea site, referred to as a “whale necropolis” due to its vast size, is located in the Diamantina Zone of the southeastern Indian Ocean and contains evidence of cetacean falls for at least 5.3 million years.

The number of icebergs in the Arctic has increased sharply since the 2000s. This is due to the destabilisation of large glaciers in north-east Greenland and parts of the Russian Arctic as well as the increasing mobility of sea ice. The result: Stones rain down from the melting icebergs, forming new hard-substrate habitats for marine life on the soft seafloor. This gradually alters the existing communities in the deep sea. At the same time, the increasing presence of icebergs also poses greater risks to shipping and fisheries. These findings were reported by a research team led by the Alfred Wegener Institute and the Woods Hole Oceanographic Institution in the journal Nature.

The deep sea is a unique ‘evolutionary engine’ with one of the richest and most unexplored sources of genetic diversity on Earth, according to a major new study that has assessed its potential to transform biotechnology and DNA sequencing technologies.

To the point:

Fruit first, fancy footwork later: A new study finds the courtship dances of the manakins – one of the most charismatic groups of birds on Earth – trace back to changes deep in their ancestry and may be linked to their fruit-rich diet.

Same answer, different routes: Manakins re-evolved a sense of sweet taste, as hummingbirds, songbirds and woodpeckers each did separately, by repurposing the receptor for savory taste.

Genome-enabled discovery: Manakins are one of the most intensively-studied groups of birds: this first set of genomes provides resources to the community to explore the genomic changes underlying their unique behaviors and physiologies.
