A new study from the University of Helsinki using miniaturized satellite-based tags revealed that during drier periods desert bats must fly further and longer to fulfil their nightly needs. According to researchers this signals their struggle in facing dry periods.
When Earth's species were rapidly diversifying nearly 500 million years ago, that evolution was driven by complex factors including global cooling, more oxygen in the atmosphere, and more nutrients in the oceans. But it took a combination of many global environmental and tectonic changes occurring simultaneously and combining like building blocks to produce rapid diversification into new species, according to a new study by Dr. Alycia Stigall, Professor of Geological Sciences at Ohio University.
Cooperative study conducted by University of Jyväskylä and Natural Resources institute Finland (Luke), revealed that enriched rearing of juvenile fish significantly enhances the survival of fish from bacterial infection commonly seen in rearing conditions. That may also improve the post release survival of the fish after stocking into the wild. The study has been published in Journal of Applied Ecology.
A new in-depth study from Ryerson University called 'The influence of environmental and health indicators on premature mortality: an empirical analysis of the City of Toronto's 140 neighborhoods' assesses the impact of several environmental, health, socioeconomic and demographic characteristics on lifespan. Authors Luckrezia Awuor and Stephanie Melles determined that premature mortality in Toronto neighborhoods was predicted by a combination of unhealthy environments and embedded socioeconomic imbalances.
'Coprolites' from the Must Farm archaeological excavation in East Anglia, UK, shows the prehistoric inhabitants were infected by parasitic worms that can be spread by eating raw fish, frogs and shellfish.
Researchers have discovered that the numbers of plant species recorded by botanists have increased in locations where the climate has changed most rapidly, and especially in relatively cold parts of the world.
Biologists Erol Akçay and Marco Smolla of the University of Pennsylvania used mathematical models to show that societies that favor generalists, who have a wide range of skills, are less well-connected than those societies that favor specialists, who are highly skilled at a smaller number of traits. The findings, have implications for improving information flow and problem-solving in settings from business to academia.
An unprecedented survey has revealed the loss of about 85 percent of historical tidal wetlands in California, Oregon, and Washington. The report, published today in PLOS ONE, also highlights forgotten estuary acreage that might now be targeted for restoration.
For their 19-year study, UC Davis scientists dug roughly 6 feet down to compare soil carbon changes in different cropping systems. They found that compost is a key to storing carbon, a strategy for offsetting CO2 emissions.
The diversity and ecology of African parasitoid wasps was studied for over a year during a project run by the Biodiversity Unit of the University of Turku in Finland. Parasitoid wasps are one of the animal groups that are the most rich in species. However, the tropical species are still very poorly known. Understanding the diversity of parasitoid wasps inhabiting rainforests is important, because tropical biodiversity is dwindling at an accelerating rate.
