Neon green gecko key to preventing Mauritian plant extinction
(4/17/2007) A vibrantly colored gecko plays a key role in a highly threatened ecological community in Mauritius reports new research published in American Naturalist. Studying plant-animal interactions in Mauritius, an Indian Ocean island famous for its extinct dodo bird, researchers found that a rare plant, Trochetia blackburniana, benefits from its proximity to Pandanus plants because they house high densities of geckos responsible for pollination. The findings, which unusually identify a lizard as a key pollinator, are significant because they provide "valuable management insights for ongoing conservation efforts to save the highly endangered flora of Mauritius.

Moray eels and groupers hunt together
(12/4/2006) Moray eels and groupers hunt together according to research published in the December 5 issue of PLoS Biology. A team of researchers lead by Redouan Bshary, a biologist at the University of Neuchatel in Switzerland, found that moray eels and groupers practice cooperative hunting in Red Sea coral reefs -- behvaior not before described outside primates and birds. The hunting habits of groupers, which are diurnal (day-active) predators that hunt in open water, are markedly different from moral eels, which are evasive nocturnal hunters that sneak through reef crevices in an attempt to ambush and corner prey. As such prey have distinctly different evasive behvaior when confronted by groupers versus morays.

Symbiotic relationships in the rainforest
(3/1/2005) Rainforests are characterized by a unique vegetative structure consisting of several vertical layers including the overstory, canopy, understory, shrub layer, and ground level. The canopy refers to the dense ceiling of leaves and tree branches formed by closely spaced forest trees. The upper canopy is 100-130 feet above the forest floor, penetrated by scattered emergent trees, 130 feet or higher, that make up the level known as the overstory. Below the canopy ceiling are multiple leaf and branch levels known collectively as the understory. The lowest part of the understory, 5-20 feet (1.5-6 meters) above the floor, is known as the shrub layer, made up of shrubby plants and tree saplings..
