Fruit bats 'vitally important' to Guam's forests

Seed dispersal on Guam, a crucial process for regenerating and diversifying the island's forests that has significantly declined with the diminishing bird population, is still being carried out by the few remaining Mariana ...

Weka: Sandwich-stealing scallywags or ecosystem managers?

Weka are often portrayed as little more than sandwich-stealing scallywags. The large, brown flightless bird's tendency to be curious and gobble any food available (whether it be an unwatched biscuit, penguin egg or endangered ...

Ancient teeth shed light on Miocene 'mouse' migration

A new species of prehistoric murine—the group of mammals that includes mice, rats, and their relatives—has been identified from fossils discovered in Lebanon. The findings, presented in Scientific Reports, represent the ...

Solitude breeds aggression in spiders (rather than vice versa)

Spiders start out social but later turn aggressive after dispersing and becoming solitary, according to a study publishing July 2 in the open-access journal PLOS Biology by Raphael Jeanson of the National Centre for Scientific ...

Assessing air-quality forecasting for London

An assessment of local and regional air-quality forecasts for London, UK is reported in the International Journal of Environment and Pollution. In their evaluation, Amy Stidworthy, Mark Jackson, Kate Johnson, David Carruthers, ...

Deciphering seed dispersal decisions of agouti rodents

Much like the squirrels and chipmunks in deciduous climates, there is a cat-sized creature in tropical regions that practices scatter hoarding – burying the seeds they find if they don't eat them right away.

Bacterial mix helps predict future change

A controlled, laboratory approach, along with computer simulations, has helped KAUST researchers to show that bacterial communities can homogenously disperse within aquatic ecosystems, even with slow-flowing water and the ...

Dispersant

A dispersant or a dispersing agent or a plasticizer or a superplasticizer is either a non-surface active polymer or a surface-active substance added to a suspension, usually a colloid, to improve the separation of particles and to prevent settling or clumping. Dispersants consist normally of one or more surfactants, but may also be gases.
