In the northern Atlantic Forest, hunting and habitat loss have eliminated most large mammals that disperse zoochoric fruits. Due to the decrease in populations of large seed dispersers, yellow-breasted capuchins (Sapajusxanthosternos) are currently one of the largest arboreal fruit-eating mammals in the region. During 26 months, we followed 14-25 capuchins aiming to (1) present data on their di...

Endophytic fungi were isolated from healthy leaves of Manilkara bidentata (Sapotaceae) collected in Puerto Rico. One leaf was collected from each of three trees. Four 5 X 20 mm panels were cut from each leaf, surface sterilized, cut into 50 1 X 2 mm pieces, and plated on malt agar. Petioles were cut into ten 1 mm segments. Fungi were isolated from 90%-95% of the leaf pieces and all of the petio...

—The diverse graminoid-dominated savannas of Central America remain poorly described. The flora and environment of a hyperseasonal coastal savanna near Sapodilla Lagoon, Stann Creek District, Belize were examined. Percent cover and frequency using plots and line transects were used to assess the community structure. We used non-metric multidimensional scaling and correlation to describe communi...

Myasthenia gravis (MG) is a neuromuscular disorder leading to fluctuating muscle weakness and fatigue. Rarely, long-term stabilization is not possible through the use of thymectomy or any known drug therapy. We present our experience with extracorporeal immunoglobulin (Ig) elimination by immunoadsorption (adsorbers with human Ig antibodies). Acetylcholine receptor antibodies (AChRAs) were measu...
