We investigated several aspects of the nesting biology of Epicharis metatarsalis Friese (Hymenoptera: Apidae) in a lowland wet-forest of northeastern Costa Rica. Five large aggregations were found 30Ð100 m from larger rivers at the La Selva Biological Station. The relatively short nesting season, from May to August, indicates that E. metatarsalis is probably univoltine. Four nests were excavate...

Background: Despite the various medicinal applications of Glyphaea brevis, no toxicology data are available that could guarantee its safety or describe possible toxic effects. We studied acute and subacute toxicity leaf aqueous extract G. brevis (GbAE) in animal models.
 Materials methods: In study, mice were given a single oral administration GbAE at doses 1000, 2000 5000 mg/kg body weigh...

Background. Various parts of Glyphaea brevis (Spreng) Monachino (Tiliaceae) find a use in traditional medicine in the treatment of pain and oedema among others. This study evaluates the anti-inflammatory, antiallergic, and antiarthritic effects of a 70% (v/v) aqueous ethanol extract of the stem bark of Glyphaea brevis in murine models. Materials and Methods. The effect of the aqueous ethanol ex...
