Conserving wildlife corridors is increasingly important for maintaining ecological and genetic connectivity in times of unprecedented habitat fragmentation. Documenting connectivity loss, assessing root causes, and exploring restoration options are therefore priority conservation goals. A 2009 nationwide assessment in Tanzania documented 31 major remaining corridors, the majority of which were described as threatened. The corridor between the Udzungwa Mountains and the Selous Game Reserve in south-central Tanzania, a major link between western and southern wildlife communities, especially for the African elephant Loxodonta africana, provides an illuminating case study. A preliminary assessment in 2005 found that connectivity was barely persisting via two remaining routes. Here we present assessments of these two corridors conducted from 2007-2010, using a combination of dung surveys, habitat mapping and questionnaires. We found that both corridor routes have become closed over the last five years. Increased farming and livestock keeping, associated with both local immigration and population growth, were the main reasons for corridor blockage. However, continued attempts by elephants to cross by both routes suggest that connectivity can be restored. This entails a process of harmonizing differing land owners and uses towards a common goal. We provide recommendations for restoring lost connectivity and discuss the prospects for preventing further loss of corridors across the country. © Trevor Jones, Andrew J.

Zootaxa | Year: 2011
In August 2009 the Natural History Museum London, Hungarian Natural History Museum and Systematic Zoology Research group, Entomological Museum in Leon and The Society for Environmental Exploration, mounted the first earthworm collection expedition to Nicaragua. No native earthworm species had previously been recorded for this country. This paper lists 18 new species records for the Country with the description of two new taxa to science: Eutrigaster (Graffia) azul sp. n. and Eutrigaster (Graffia) nicaraoi sp. n. New data on the species Eutrigaster (Eutrigaster) oraedivitis Cognetti, 1904 is also presented here. Copyright © 2011 Magnolia Press.
