Abstract

In November 2005 Calyptrogyne brachystachys palm inflorescences were examined for the presence of phoretic bat mites (tribe Melichari) in the Cloud Forest of Monteverde. Sixty-seven Calyptrogyne brachystachys plants were studied over a two-week period for flower and inflorescence phenology. Forty-six inflorescences were examined thoroughly for mite presence of which 11 were found to harbor mites. Flower phenology studies suggest a temporary flowering lag. Abundances of mites on both inflorescence and site scales were found at much lower frequencies than the Atlantic slope (Tschapka and Cunningham 2004), The lower abundance in Monteverde is attributed to abiotic differences such as recent weather patterns and biotic influences such as low flower abundance. Se examinaron inflorescencias de la palma Calyptrogyne brachsrachys en Noviembre del 2005 para determinar la presencia o ausencia de los ácaros foréticos en murciélagos (Tribu Melichari) en el bosque nuboso de Monteverde. Se estudiaron sesenta y siete plantas de Calyptrogyne brachsrachys por dos semanas para averiguar la fenología de las flores e inflorescencias. Once de las cuarenta y seis inflorescencias examinadas contenían ácaros. Los estudios de la fenología de las inflorescencias sugieren que hay un retraso temporal en la floración. Las abundancias de ácaros, examinadas por escala del sitio e inflorescencia, ocurrieron con frecuencias más bajas que en la Costa Atlántica de Costa Rica (Tschapka and Cunningham 2004). La abundancia más baja tal vez sea debida a las diferencias abióticas tales como patrones climáticos recientes e influencias bióticas como la baja abundancia de las flores.
