Small mammals use Borneo pitcher plant as toilet in exchange for nectar

(11/08/2011) Tree shrews and nocturnal rats in the forests of Borneo have a unique relationship with carnivorous pitcher plants. The mammals defecate, and the pitchers are happy to receive. A study published on May 31 in the Journal of Tropical Ecology shows a species of giant mountain pitcher plants (Nepenthes rajah) supplements its diet with nitrogen from the feces of tree shrews (Tupaia montana) that forage in daylight and summit rats (Rattus baluensis) active at night. When the small mammals lick nectar from the underside of the pitcher’s lid, they stand directly over the jug-shaped pitcher organ.


Invasive ant interferes with gecko's role in pollinating endangered plant

(11/28/2008) Invasive ants are destroying the symbiotic relationship between a colorful gecko and a critically endangered flower on the island of Mauritius, reports New Scientist citing research published by Dennis Hansen and Christine Müller in the journal Biotopica.


Lemurs are key to health of Madagascar's rainforests

(06/12/2008) Lemurs play a key role in the health of Madagascar's tropical rainforests said a renowned primatologist speaking at a meeting of conservation biologists in Paramaribo, Suriname.


Disappearance of elephants, giraffes causes ecological chain reaction

(01/10/2008) The disappearance of elephants, giraffes and other grazing animals from the eastern African savanna could send ecological ripple effects all the way to the savanna's ants and the acacia trees they inhabit, warns a new study published in the journal Science.


Neon green gecko key to preventing Mauritian plant extinction

(04/17/2007) 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.


Lavender and symbiotic fungi key to Cypress reforestation in Morocco

Moray eels and groupers hunt together

(12/05/2006) 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.
