Climate change to affect fish sizes and complex food webs
(University of Tasmania) Global climate change will affect fish sizes in unpredictable ways and, consequently, impact complex food webs in our oceans, a new IMAS-led study has shown.Led by IMAS and Centre for Marine Socioecology scientist Dr Asta Audzijonyte and published in the journal Nature Ecology and Evolution, the study analysed three decades of data from 30 000 surveys of rocky and coral reefs around Australia.
North Atlantic’s capacity to absorb CO2 overestimated, study suggests
The North Atlantic may be a weaker climate ally than previously believed, according to a study that suggests the ocean’s capacity to absorb carbon dioxide has been overestimated. A first-ever winter and spring sampling of plankton in the western North…

Deep-sea worms and bacteria team up to harvest methane
(California Institute of Technology) Scientists uncover an unusual partnership at the bottom of the ocean.
Plant disease primarily spreads via roadsides
A precise statistical analysis reveals that on the Åland Islands a powdery mildew fungus that is a common parasite of the ribwort plantain primarily spreads via roadsides because traffic raises the spores found on roadsides efficiently into the air.
‘The losses could be profound’: floods wreak havoc on wildlife
For 900 years, Lugg and Hampton wildflower meadows in Herefordshire have bloomed into a wash of colour in spring. These fertile meadows were highly prized, and the Norman lords who owned them used the hay crop to help fund Hereford’s…
Landmark study concludes marine life can be rebuilt by 2050
(King Abdullah University of Science & Technology (KAUST)) An international study recently published in the journal Nature that was led by KAUST professors Carlos Duarte and Susana Agustí lays out the essential roadmap of actions required for the planet’s marine life to recover to full abundance by 2050.
When warblers warn of cowbirds, blackbirds get the message
(University of Illinois at Urbana-Champaign, News Bureau) This is the story of three bird species and how they interact. The brown-headed cowbird lays its eggs in other birds’ nests and lets them raise its young — often at the expense of the host’s nestlings. To combat this threat, yellow warblers have developed a special ‘seet’ call that means, ‘Look out! Cowbird!’ In a new study, researchers report that red-winged blackbirds respond to the seet call as if they know what it means.
Sturgeon genome sequenced
Sturgeons lived on earth already 300 million years ago and yet their external appearance seems to have undergone very little change. A team of researchers has now succeeded in sequencing their genome, delivering a missing piece of the puzzle essential to understanding the ancestry of vertebrates.
Where lions roam: West African big cats show no preference between national parks, hunting zones
(University of Michigan) West African lions are a critically endangered subpopulation, with an estimated 400 remaining and strong evidence of ongoing declines.
