Remains of artificial turf is an important source of pollution of the aquatic environment      (via sciencedaily.com)     Original source 

Every year, around 1,200 and 1,400 artificial turf sports fields are installed in the European Union. These fields are made up of synthetic fibers, mainly plastics, that mimic the appearance of natural grass. Recently, scientists conducted a study that characterizes and quantifies the presence of artificial turf fibers in samples collected from surface waters of the Catalan coast and the Guadalquivir River. The findings indicate that artificial turfs can be an important source of pollution in the aquatic environment, accounting for up to 15% of the plastics larger than 5 mm in length that are found floating in the aquatic environment.

Study clearly identifies nutrients as a driver of the Great Atlantic Sargassum Belt      (via sciencedaily.com)     Original source 

Under normal conditions, the floating macroalgae Sargassum spp. provide habitat for hundreds of types of organisms. However, the Great Atlantic Sargassum Belt (GASB) that emerged in 2011 has since then caused unprecedented inundations of this brown seaweed on Caribbean coastlines, with harmful effects on ecosystems while posing challenges to regional economies and tourism, and concerns for respiratory and other human health issues.

Evolutionary secrets of 'Old Tom' and the killer whales of Eden revealed by genetic study      (via sciencedaily.com)     Original source 

Evolutionary biologists have for the first time decoded the genetic lineage of a famous killer whale and a pod that once worked alongside whale hunters off the coast of Australia. In the Australian tradition of claiming New Zealand's celebrities as its own, Old Tom, the leader of a pod of killer whales that famously helped whalers hunt baleen whales in the 20th century, has ancestral links to modern-day killer whales in New Zealand, according to new DNA research. Old Tom also shared a common ancestor with killer whales from Australasia, the North Pacific, and North Atlantic Oceans, but is most similar to modern New Zealand killer whales. However, most of Tom's DNA code is not found in other killer whales globally suggesting that the killer whales of Eden may have become extinct locally.

Discovery of invisible nutrient discharge on Great Barrier Reef raises concerns      (via sciencedaily.com)     Original source 

Scientists using natural tracers off Queensland’s coast have discovered the source of previously unquantified nitrogen and phosphorus having a profound environmental impact on the Great Barrier Reef. Groundwater discharge accounted for approximately one-third of new nitrogen and two-thirds of phosphorus inputs, indicating that nearly twice the amount of nitrogen enters the Reef from groundwater compared to river waters.

Newly-discovered 'margarita snails' from the Florida Keys are bright lemon-yellow      (via sciencedaily.com)     Original source 

A newly-discovered, bright yellow snail has been discovered in the Florida Keys and named in honor of Jimmy Buffet's song 'Margaritaville.' The lemon-colored marine snail, along with its lime-green cousin from Belize, is the subject of a recent study ; researchers think these snails' bright colors might help deter predators.

Consistent metabolism may prove costly for insects in saltier water      (via sciencedaily.com)     Original source 

Increased salinity usually spells trouble for freshwater insects like mayflies. A new study finds that the lack of metabolic responses to salinity may explain why some freshwater insects often struggle in higher salinity, while other freshwater invertebrates (like mollusks and crustaceans) thrive.

DNA from discarded whale bones suggests loss of genetic diversity due to commercial whaling      (via sciencedaily.com)     Original source 

Commercial whaling in the 20th century decimated populations of large whales but also appears to have had a lasting impact on the genetic diversity of today’s surviving whales, new research shows.

Sustainable protection of rapidly subsiding coastlines with mangroves      (via sciencedaily.com)     Original source 

Along the Asian coast lines there are many areas where rural communities experience alarming rates of sea level rises due to land subsidence up to 10 cm per year. This causes tremendous challenges on how to live there and protect these coasts. Scientists have now investigated the potential and limitation of mangrove restoration as a cost-effective and sustainable solution for coastal protection in rapidly subsiding areas.

Did animal evolution begin with a predatory lifestyle?      (via sciencedaily.com)     Original source 

Surprising findings on the development of sea anemones suggest that a predatory lifestyle molded their evolution and had a significant impact on the origin of their nervous system. The researchers were able to show that the young life stages (larvae) of the small sea anemone Aiptasia actively feed on living prey and are not dependent on algae. To capture its prey, the anemone larvae use specialized stinging cells and a simple neuronal network.
