New bird to science emphasizes the critical need to conserve the remaining dry forests of Madagascar
Date:2/23/2011

In a recent issue of the scientific journal Zootaxa, researchers from Madagascar and the United States described a new species of forest-dwelling rail. The new bird was named Mentocrex beankaensis, with the genus Mentocrex being endemic to Madagascar and the new species beankaensis being coined after the type locality, the Beanka Forest in western central Madagascar. This species was distinguished from another in the same genus, known from the eastern portion of the island, based on aspects of size, plumage, and DNA.

The project resulting in this description was the joint efforts of scientists from the University of Antananarivo and Association Vahatra in Madagascar and the Pritzker Laboratory for Molecular Systematics and Evolution at The Field Museum in Chicago. Marie Jeanne Raherilalao and Steve Goodman conducted the morphological portion of the study, and the molecular genetics aspects by Nicholas Block, a graduate student with the University of Chicago's Committee on Evolutionary Biology who is based at The Field Museum.

The dry forests of western Madagascar have been drastically reduced in size. Estimates proposed by the World Wildlife Fund (WWF) indicate that 97 percent of the original forest cover in this portion of the island has disappeared since humans arrived some 2,500 years ago. Over the past decades these remaining dry forest areas have been the sites of numerous discoveries of plant and animal species new to science. The Beanka Forest is a largely intact area resting on exposed limestone formation with razor-sharp pinnacle like structures, which are known in Malagasy, the language of Madagascar, as tsingy.

The Beanka Forest in a remote portion of the island is managed since late 2007 by the Association Biodiversity Conservation Madagascar (BCM) and funded by Bioculture (Mauritius) Ltd., which has started programs for the socio-economic development of surrounding communities, forest re
