University of Hong Kong - codeveloped automated laser-scanning ‘hunter drone’ seeks out fossils, minerals and biological targets

Science fiction has machine-intelligent hunter drones and they have now become science fact with a new University of Hong Kong (HKU) - codeveloped autonomous ‘hunter drone’ that seeks out targets at night using a scanning laser.

Wind beneath their wings –study finds albatrosses fine-tuned to wind conditions

A new study of albatrosses has found that wind plays a bigger role in their decision to take flight than previously thought, and due to their differences in body size, males and females differ in their response to wind.

How fish got onto land, and stayed there

Research on blennies, a family of fish that have repeatedly left the sea for land, suggests that being a ‘jack of all trades’ allows species to make the dramatic transition onto land but adapting into a ‘master of one’ allows them to stay there.

African lion numbers are being overestimated by survey methods

Two Griffith led collaborations published this week indicate that Lion populations in Africa may be lower than current estimates suggest. TeaserBlah

Research shows recovering pine marten population benefits red squirrels, but the grey squirrel still poses a problem in urban areas

Research led by Queen’s University Belfast has found that whilst red squirrels are responding positively to the increased presence of the pine marten across Ireland and Britain, its ability to control the grey squirrel is limited by the lack of forest cover and the presence of urban refugia.

Human presence weakens social relationships of giraffes

Living close to human settlements disturbs the social networks of giraffes. They have weaker bonds with other giraffes and fewer interactions with other members of the species, an international study led by the University of Zurich on the social structure of over 500 female giraffes in Tanzania has shown.

New evidence on bed bug burden in urban neighborhoods

Researchers at UMass Amherst find more risk of bed bugs in poorer, crowded urban areas.

Birds, bees and butter – new study underlines importance of biodiversity for crop production and West African livelihoods

Shea trees are in important crop in Senegal and Uganda and they benefit from bees pollinating their flowers to produce fruit. New research finds that in sites with low tree and shrub diversity, fruit production is severely limited by a lack of pollination.

Lack of insects in cities limits breeding success of urban birds

Urban insect populations would need to increase by a factor of at least 2.5 for urban great tits to have same breeding success as those living in forests.

How does an increase in nitrogen application affect grasslands?

Researchers at the University of Bern share the first results of the largest biodiversity-ecosystem functioning experiment in Switzerland

Indigenous voices reveal key strategies for navigating the challenging return of sea otters

Severe coral loss leaves reefs with larger fish but low energy turnover

Research on the Great Barrier Reef has found severe coral loss to be associated with substantial increases in the size of large, long-living herbivorous fish. However, decreased recycling of this fish biomass could leave the ecosystem vulnerable to crashing.

Wolf spiders may turn to cannibalism in a warming Arctic

Wolf spiders in a warming Arctic are getting bigger, reproducing more and eating different foods. Including other spiders.

Nature reserve under water

Researchers present a new method for establishing protection zones for highly biodiverse deep sea areas.

“Superfoods”, a super-impact on the environment

Eating quinoa may not be as “eco-friendly” as you think: the environmental impact of “superfoods” under the spotlight.
