Consumo de polen de una colonia de maternidad de Leptonycteris curasoae yerbabuenae en Tuxtla Gutierrez, Chiapas, México

Abstract

WE REPORT POLLEN CONSUMPTION OF LEPTONYCTERIS CURASOAE YERBABUENAE BASED ON THE ANALYSIS OF 62 ADULT FEMALE PELLETS (16 PREGNANT, 40 LACTANT, FIVE POSLACTANT AND ONE FEMALE WITHOUT REPRODUCTIVE SIGNS) FROM A MATERNITY COLONY IN CUEVA LOS LAGUITOS, TUXTLA GUTIERREZ, CHIAPAS. WE TOOK SAMPLES TWICE A MONTH, FROM OCTOBER 1996 TO JANUARY 1997, AND WE GATHERED BAT PELLETS WERE INCLUDED IN GELATINE. THE MICROSCOPIC ANALYSIS ALLOWED THE IDENTIFICATION OF POLLEN GRAINS OF 19 SPECIES, THE MOST ABUNDANT BEING CEIBA AESCULIFOLIA, C. PENTANDRA, AGAVE SP., ASTERACEAE, BAUHINIA UNGULATA, OPERCULINA SP. AND BAUHINIA SP. CHI-SQUARE ANALYSIS (Z2) INDICATED THAT NUTRITIOUS DIFFERENCES EXIST FOR REPRODUCTIVE STATE, MONTH AND REPRODUCTIVE STATE/MONTH, BUT THESE DIFFERENCES CAN BE DUE THE TEMPORARY READINESS OF THE FOOD MORE THAN TO NUTRITIOUS PREFERENCES.
