Ancient fish ponds in the Bolivian savanna supported human settlement
A network of fish ponds supported a permanent human settlement in the seasonal drylands of Bolivia more than one thousand years ago, according to a new study.

Parents unknown: Mysterious larvae found in Panama's two oceans
Animals in hard-to-reach places, especially strange, 'unattractive,' animals, may completely escape our attention. We don't know what their role is in the environment. In fact, we don't even know they exist. New research may double the number of species of a little-known marine creature, based on DNA studies of its larvae.

Plastic pollution harms the bacteria that help produce the oxygen we breathe
Ten percent of the oxygen we breathe comes from just one kind of bacteria in the ocean. Now laboratory tests have shown that these bacteria are susceptible to plastic pollution, according to a new study.

Understanding relationship break-ups to protect the reef
Unravelling the secrets of the relationship between coral and the algae living inside it will help prevent coral bleaching, researchers believe. By using genomic data to look for genes that enhance resilience in the algae, researchers hope to help coral adapt to the environmental shifts created by climate change.

Use of robots and artificial intelligence to understand the deep sea
Artificial intelligence (AI) could help scientists shed new light on the variety of species living on the ocean floor, according to new research.

New type of highly sensitive vision discovered in deep-sea fish
The deep sea is home to fish species that can detect various wavelengths of light in near-total darkness. Unlike other vertebrates, they have several genes for the light-sensitive photopigment rhodopsin, which likely enables these fish to detect bioluminescent signals from light-emitting organs.

How sea level rise affects birds in coastal forests
Saltwater intrusion changes coastal vegetation that provides bird habitat. Researchers found that the transition from forests to marshes along the North Carolina coast due to climate change could benefit some bird species of concern for conservation.

The bird that came back from the dead
New research has shown that the last surviving flightless species of bird, a type of rail, in the Indian Ocean had previously gone extinct but rose from the dead thanks to a rare process called 'iterative evolution'.

Dexterous herring gulls learn new tricks to adapt their feeding habits
Observations of herring gulls have shown how the coastal birds have developed complicated behavior to 'skin' sea creatures to make them safe to eat. Researchers think this feeding habit may be a response to urbanization and changes in food availability.

Low oxygen levels could temporarily blind marine invertebrates
Scientists have found that low oxygen levels in seawater could blind some marine invertebrates. The results are the first demonstration that vision in marine invertebrates is highly sensitive to the amount of available oxygen in the water.

Radioactive carbon from nuclear bomb tests found in deep ocean trenches
Radioactive carbon released into the atmosphere from 20th-century nuclear bomb tests has reached the deepest parts of the ocean, a new study finds. Crustaceans in deep ocean trenches have incorporated this 'bomb carbon' into the molecules that make up their bodies.

Water flea can smell fish and dive into the dark for protection
Zoologists have discovered the messenger substance responsible for the flight of the small planktonic crustacean Daphnia from fish in lakes. This animal's dive into deeper waters has significant consequences for the concentration of algae in the lake's ecosystem. The scientists hope that in future, a better understanding of this interaction might help restore the biological balance in lakes.

Threatened sturgeon learns for the fitness
An international team is providing one of the first proofs of the complex learning behavior of fish in a recent study. The Atlantic sturgeon is thought to be locally extinct in Germany. Scientists are working toward sturgeon reintroduction and are investigating whether sturgeon training can increase their fitness for the wild. An important fitness factor is their feeding behavior. A two-week 'learning lead' made the search for food more efficient.

Freshwater mussel shells were material of choice for prehistoric craftsmen
Researchers have discovered that 6000-years-ago people across Europe shared a cultural tradition of using freshwater mussel shells to craft ornaments.

New species of fish parasite named after Xena, the warrior princess
A study of crustacean parasites attaching themselves inside the branchial cavities (the gills) of their fish hosts was conducted in order to reveal potentially unrecognized diversity of the genus Elthusa in South Africa. While there had only been one known species from South Africa, a new article adds another three to the list, including one named after fictional character Xena because of the strong appearance of the females.

Shipwrecks off North Carolina, U.S. coast harbor tropical migrants
Shipwrecks and sunken structures off the North Carolina coast may act as stepping stones for tropical fish searching for favorable habitats at or beyond the edge of their normal geographic range. A study finds these fishes prefer artificial reefs over natural ones and suggests linked networks of these human-made structures could be used to aid the survival of the ecologically and economically important species.

Oxygen linked with the boom and bust of early animal evolution
Extreme fluctuations in atmospheric oxygen levels corresponded with evolutionary surges and extinctions in animal biodiversity during the Cambrian explosion, finds a new study.

Nature's dangerous decline 'unprecedented,' species extinction rates 'accelerating'
Nature is declining globally at rates unprecedented in human history -- and the rate of species extinctions is accelerating, with grave impacts on people around the world now likely, warns a landmark new report from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES).

New strain of canine distemper in wild animals in NH, VT
A distinct strain of canine distemper virus, which is a widespread virus of importance to wildlife and domesticated dogs, has been identified in wild animals in New Hampshire and Vermont, according to pathologists.

Seagrass' strong potential for curbing erosion
A new study shows how seagrass can help to protect shorelines against erosion and help to mitigate damage from rising sea level, potentially providing useful guidance for seagrass restoration efforts.
