Plant communication: Sagebrush engage in self-recognition and warn of danger

...hat sagebrush (Artemisa tridentata) became more resistant to herbivores after exposure to volatile cues from experimentally damaged neighbors." The ecologists wrote that "naturally occurring herbivores caused similar responses as experimental clipping with scissors and active cues were released for up to thr...

Early Man Was A Prey Rather Than A Predator

...n evolved from being a prey rather than a predator, "In fact, all diurnal primates (those active during the day) live in permanent social groups. Most ecologists agree that predation pressure is one of the major adaptive reasons for this group living. In this way there are more eyes and ears to locate the preda...

The value of variation: Ecologists consider the causes and consequences

KNOXVILLE, Tenn. Consider the case of the three-spine stickleback. These tiny fish that thrive in oceans and in fresh water might appear to be the same, yet ecologists are finding that they are actually a diverse collection of very specialized individuals. Understanding the ecological causes ...

Studies of small water fleas help ecologists understand population dynamics

(Santa Barbara, Calif.) A study of populations of tiny water fleas is helping ecologists to understand population dynamics, which may lead to predictions about the ecological consequences of environmental change. The study is published in today's issue of the journal Nature . The water flea, ...

Biofuels and biodiversity don't mix, ecologists warn

Rising demand for palm oil will decimate biodiversity unless producers and politicians can work together to preserve as much remaining natural forest as possible, ecologists have warned. A new study of the potential ecological impact of various management strategies published in the British Ecolog...

Predators keep the world green, ecologists find

Predators are, ironically, the key to keeping the world green, because they keep the numbers of plant-eating herbivores under control, reports a research team lead by John Terborgh, a professor of environmental science at Duke University's Nicholas School of the Environment and Earth Sciences. Th...

Internet viruses help ecologists control invasive species

Studying how computer viruses spread through the internet is helping ecologists to prevent invasions of non-native species. New research published today in the British Ecological Society's Journal of Applied Ecology, describes the use of network theory to predict how the spiny water flea - a native...
