A research group of scientists from North America, Europe and Africa concluded that animals' ability to respond to climate change likely depends on how well they modify their habitats, such as nests a...
This paper presents an introductory synthesis for mapping potential habitats of arthropod vectors responsible for animal trypanosomiasis diseases in Northern Nigeria, where there is high production of...
An unprecedented study integrating data from around the globe has shown that honey bees are the world’s most important single species of pollinator in natural ecosystems and a key contributor to natur...
Mathematics of gamete diffusion and fertilization in aquatic habitats
Cold-Water Corals is the first comprehensive synthesis of one of the most active areas of current deep-sea research. It is a timely contribution to this field, which is experiencing a rapid increase i...
Modern mountain climbers typically carry tanks of oxygen to help them reach the summit. It’s the combination of physical exertion and lack of oxygen at high altitudes that creates one of the biggest c...
An extensive study of global habitat fragmentation--the division of habitats into smaller and more isolated patches--points to major trouble for the world's ecosystems.The study shows that 70 percent ...
EUGENE, Ore. — Nov. 18, 2014 — Leave it to long-dead short-tailed shrew and flying squirrels to outfox climate-modelers trying to predict future habitats.
Antarctic krill (Euphausia superba) were sampled in contrasting habitats: a seasonally ice-covered deep ocean (Lazarev Sea), ice-free shelves at their northern range (South Georgia) and the Antarctic...
The Ha˚kon Mosby Mud Volcano is a highly active methane seep hosting different chemosynthetic communities such as thiotrophic bacterial mats and siboglinid tubeworm assemblages. This study focus...
Historical drainage improvements have created complex hydrological regimes in many low-lying, wet coastal grassland areas. The manipulation of ditch water levels is a common management technique to m...
Alongside other countries that are signatories to the UNECE Convention Long Range Transboundary on Air Pollution, the UK is committed to reducing the impact of air pollution on the environment. To adv...
We sampled three habitats (main channel, side channels, and backwater lakes) during 2 yr along 32 km of the Illinois River to compare zooplankton distribution and dynamics, as well as evaluate the pos...
Oxytropis glabra (Lam.) DC. (Papilionaceae) and Carex pycnostachya Kar. & Kir. (Cyperaceae) are reported as new records for the flora of Iran. These species occur in wetland habitats sharply embedded ...
