Gene chips forecast ecological impacts of climate change

... Coastal marine ecosystems, from the intertidal zone to the continental shelves, are particularly vulnerable to global climate change. The physical factors that are changing in these systems are more than temperature alone. Due to the interaction of oceans with the atmosphere and the role of the ocean ...

Tracking sperm whales and jumbo squid

...of the world’s largest ecosystems, the mesopelagic zone [650 to 3,300 feet below sea level]," the authors wrote. "How sperm whales search for, detect and capture their prey remains uncertain." To find out, the researchers traveled to the Gulf of California, also called the Sea of Cortez—a narrow stretc...

Study finds antibiotic resistance in poultry even when antibiotics were not used

... they were still well above the reasonable comfort zone for antibiotic resistance ?roughly five to 10 percent. Seventy-three percent of the bacteria from one flock in the antibiotic-free commercial group were resistant to the drug oxytetracycline, for example, while 90 percent were resistant to the dru...

Parasites' impact goes beyond host to affect ecosystem

... grazing normally on algae in the rocky intertidal zone of the North Atlantic, is that you may not be infected by a parasite. But the better news is, according to new research from the University of New Hampshire, that you might have more to eat if plenty of your neighbors are infected. The research, pub...

Why do oysters choose to live where they could be eaten?

...t more than 95 percent of an oyster reef is a safe zone for larvae. Given this low cannibalism risk at settlement, future payoffs appear to have driven the evolution of a gregarious settlement cue that promotes group living in oysters. ...

Massive herds of animals found to still exist in Southern Sudan

...Boma National Park. The team also identified a key zone of semi-arid habitat supporting several species, which will be proposed as a new protected area. (OVER) In an effort to protect this newly discovered natural resource, WCS has signed cooperation agreements with both GoSS and its Ministry of Env...

Research identifies protein that signals flowering in squash plants

...s of such induced plants showed that the infection zone of ZYMV was not coincident with the plant’s floral meristems, indicating that FT mRNA is unlikely to be the florigenic signal in this system. Next, heterografting studies were conducted using flowering Cucurbita maxima (pumpkin) stocks (the stock is ...
