Managing an endangered river across the US–Mexico border


A new IIASA study shows how improving communication and involvement could bring consensus solutions for the embattled Rio Grande/Bravo, which is shared between the USA and Mexico.

Pathogenic bacteria hitchhiking on tiny plastic particles to North and Baltic Seas?


With increasing water temperatures comes an increasing likelihood of potentially pathogenic bacteria appearing in the North and Baltic Seas. Scientists have now demonstrated that a group of such bacteria known as vibrios can survive on microplastic particles.

Hunting for Mars-like life a kilometre below Earth’s surface


Kate Ravilious takes an 8-minute lift ride to an underground lab in Yorkshire, UK, doing research that could help NASA’s Mars 2020 rover mission find life

‘Biblical’ moth influx threatens to devastate crops

Scientists have learned that cabbage and cauliflower crops could potentially be “devastated” by an infestation of moths from continental Europe.

More is better: Diversity, number of soil animals determine leaf decomposition in the forest

Small animals that decompose fallen leaves in the forest form complex food webs and are essential to a functioning ecosystem. A study comprising over 80 forests in Germany and on Sumatra (Indonesia) has now shown that two factors particularly influence this function when examined over larger landscapes: the number of animals and their species diversity. In previous studies, the connection between biodiversity and ecosystem functioning had been investigated mostly in small test areas.

Coral bleaching solution could be just beneath the surface

A ‘lifeboat’ for coral reefs could lie in deeper mesophotic coral ecosystems.

Microplastics killing fish before they reach reproductive age, study finds

Tiny particles of plastic litter in oceans causing deaths, stunted growth and altering behaviour of some fish that feed on them, research shows

Saharan dust affects marine bacteria, potential pathogen Vibrio

Originally Published by Earth & Climate News — ScienceDailyIron can be hard to hard to come by in open marine waters — except each summer, when atmospherically transported dust from north Africa’s Sahara Desert provides pulses of biologically important nutrients, including iron, to the tropical marine waters of the Caribbean and southeastern US. Researchers found […]

Pizzly or grolar bear: grizzly-polar hybrid is a new result of climate change

Deep-water seaweed evolved into a multi-cellular plant more than 540 million years ago

Originally Published by Earth & Climate News — ScienceDailyThe discovery of a deep-water seaweed that evolved into a multi-cellular plant more than 540 million years ago has added a new branch to the tree of life, according to biologists. Topic: Biodiversity
