New discovery suggests trees evolved camouflage defense against long extinct predator
... of humans New Zealand had no native land mammals, but was home to moa, giant flightless birds, closely related to the modern ostrich and the top herbivore
predator in the food chain. However moa were hunted to extinction 750 years ago.

Diversity of plant-eating fishes may be key to recovery of coral reefs
... mixes of herbivorous species, we might see more rapid recovery of the reefs."
Believed to be the first study to demonstrate the importance of herbivore
diversity in enhancing the growth of coral reefs, the research was conducted at the National Undersea Research Center in Key Largo, Florida. It was ...
Emerging field of neuroecology is showcased in December issue of the Biological Bulletin
... MBL, WOODS HOLE, MA A plant laces its leaves with a noxious chemical, forcing a hungry herbivore
to choose between starving, eating a potentially toxic item, or moving on. A newt secretes a potent neurotoxin to defend against predators, ...
Parasites' impact goes beyond host to affect ecosystem
... Hampshire, looks at parasitism by the trematode Cryptocotyle lingua in Littorina littorea, a snail known as the common periwinkle and the dominant herbivore
in the intertidal zone. "We wanted to find out what was this parasite’s impact on the community," says Byers, who advised Wood during the research, ...

Batfish to the rescue!
... GBR reefs may be closely tied to the fate of mangroves and their suitability for batfish recruitment."
Batfishes may be one of the last intact herbivore
populations capable of reversing serious weed overgrowth of inshore coral reefs, he adds. The reef has already all-but lost one major group of ...
Plants tell caterpillars when it's safe to forage
... in a new study in the open access journal PLoS Biology, Kaori Shiojiri, Rika Ozawa, and Junji Takabayashi show that plant signals can indeed regulate herbivore

Tyrannosaur survivorship -- tough times for teens
... quarry. It is the best evidence that exists to suggest that tyrannosaurids may have been gregarious, or pack, animals. The almost complete lack of herbivore

Invasive exotic plants helped by natural enemies
... times to make room for their own domesticated and feral herbivores from the old world," said Parker.
He also noted that this radical shift in herbivore
composition may favor exotic plants over natives.
Recent research, including a paper authored by Parker in Ecology Letters last year, suggests ...
