Healthy soil lifts animal weight

Individual pastures on livestock farms yield surprisingly dissimilar benefits to a farm's overall agricultural income, and those differences are most likely attributable to the varying levels of "soil health" provided by its grazing livestock, reveals a study published today.

The study, produced by an interdisciplinary team of 13 scientists and two PhD students from Rothamsted Research,...

Crowded urban areas have fewer songbirds per person

People in crowded urban areas -- especially poor areas -- see fewer songbirds such as tits and finches, and more potential "nuisance" birds, such as pigeons, magpies and gulls, new research shows.

The University of Exeter and the British Trust for Ornithology examined ratios of birds-to-people and found areas of high-density housing have fewer birds overall...

Extremely fast dives help peregrine falcons maneuver to catch agile prey

Computer simulations of peregrine falcon attacks show that the extreme speeds reached during dives from high altitudes enhance the raptors' ability to execute maneuvers needed to nab agile prey that would otherwise escape. Robin Mills and colleagues of the University of Groningen, Netherlands, and Oxford University, UK, report this discovery in PLOS Computational Biology.

Viruses can evolve in parallel in related species

Viruses are more likely to evolve in similar ways in related species -- raising the risk that they will "jump" from one species to another, new research shows.

Scientists from the universities of Exeter and Cambridge compared viruses that evolved in different species and found "parallel genetic changes" were more likely if two host species were...

Droughts mean fewer flowers for bees

Bees could be at risk from climate change because more frequent droughts could cause plants to produce fewer flowers, new research shows.

Droughts are expected to become more common and more intense in many parts of the world, and researchers studied the impact on flowering plants using a field experiment.

They found that drought roughly halved the...
