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?

MicroplasticsVibro

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.

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

BeechForest
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

GlobalAerosols
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 […]
