Caron Lett, University of York An international team of researchers has found that the majority of threatened species are ‘invisible’ when using modern methods to predict species distributions under climate change. Using African amphibians as a case study, the researchers found that more than 90 percent of the species listed as threatened on The IUCN Red List of Threatened Species are omitted by the most popular tools for species distribution modelling. The study, led by...

Extreme Weather Caused By Climate Change Decides Distribution Of Insects
2014-02-21 09:58:26

Christina Troelsen and Johannes Overgaard, Aarhus University Extreme weather caused by climate change in the coming decades is likely to have profound implications for distributions of insects and other invertebrates. This is suggested by a new study of insects in tropical and temperate regions of Australia. As climate change is progressing, the temperature of our planet increases. This is particularly important for the large group of animals that are cold-blooded (ectothermic),...

Moonlight Can Be A Benefit For Some Prey Species
2013-10-22 17:12:37

Lee Rannals for redOrbit.com – Your Universe Online According to a new study published online recently in the Journal of Animal Ecology, not all animal species are negatively affected by moonlight. One prevailing theory in ecology is that moonlight increases predation risk, but Laura Prugh, a wildlife biologist at the University of Alaska, Fairbanks, says that is not always the case. "Ecologists have long viewed the darkness of a moonless night as a protective blanket for...

Systematic conservation planning is a multiple-objective process. Identification of important areas and species with high conservation priority is two of the research objectives. China is one of mega-biodiversity countries of the world. Along with rapid economic development and environmental degeneration, native and endemic species of China are confronting growing threats in the last two decades. It is an urgent agenda to set up relevant conservation policies, researches and decision supports...

Victorian-Era Map Helps Researchers Redraw Distribution Of Biodiversity
2012-12-21 13:36:25

Brett Smith for redOrbit.com - Your Universe Online Ecologists have collected massive amounts of data over the past 130 years and a research team led by University of Copenhagen scientists has used that wealth of information to redraw a Victorian map used to illustrate the geographic distribution of animals. The original map by the renowned English naturalist Alfred Russel Wallace, with assistance from Charles Darwin, has been in use since it was drawn up in 1874, when it established...

Species Interactions Could Be Affected By Global Warming
2012-06-23 09:06:42

Yale and University of Connecticut researchers report that more extinctions will take place due to global warming should "scientists fail to account for interactions among species in their models." According to Phoebe Zarnetske, primary author and postdoctoral fellow at Yale´s School of forestry & Environmental Studies department, “Currently, most models predicting the effects of climate change treat species separately and focus only on climatic and environmental drivers."...

Marine and terrestrial species will likely differ in their responses to climate warming, new research by Simon Fraser University and Australia´s University of Tasmania has found. The study, published this week in Nature Climate Change, provides insights into why and how species are moving around the globe in response to global warming. Researchers gathered published data from tests determining the physiological temperature limits — tolerance to heating and cooling levels - on...

A new study led by Carrie Schloss, an analyst in environmental and forest sciences at the University of Washington, finds that nine percent of the Western Hemisphere's mammals, and nearly forty percent in particular regions, will fall victim to the changing climate. Some mammals are merely too slow to escape climate change in their natural habitats and are unable to move into different areas. The study seeks to understand if the mammals can actually adapt to these conditions by moving or not....

Hundreds of rare, endemic species in the Central Andes remain unprotected and are increasingly under threat from development and climate change, according to a Duke University-led international study. "These species require unique ecological conditions and are particularly vulnerable to changes in the environment or climate. Yet our analysis shows that region-wide, about 80 percent of the areas with high numbers of these species lack any protection," said Jennifer Swenson, assistant...

Competition plays a decisive role in climate change adaptation Species distribution models are of only limited use in predicting the future distribution of mammals. This is the finding of a study of the climate niches of 140 indigenous European mammals. The researchers analyzed data on species distribution, climate, land cover and topography, as well as the phylogenetic information of the species. Judging by the large differences in climate niches even for closely related species, mammals...


Word of the Day
humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
