Population trends of the mantled howler monkey groups of La Pacifica, Guanacaste, Costa Rica
A complete survey of La Pacifica in Guanacaste Province, Costa Rica was conducted in July 1984 in order to determine whether the howler (Alouatta palliata) population had declined since 1972 as a result of deforestation. During the 6-day survey, 257 howlers were located, representing 16 different social groupings and nine solitary animals. The total number of howlers, the number and location of gr

The use of stable isotopes in the study of photosynthesis in freshwater plants
The ratio of 13C/12C for photosynthetic tissues of 22 aquatic species was unrelated to photosynthetic pathway. In three aquatic environments CAM and non-CAM species were shown to have similar δ13C values. Although these CAM species derive up to half of their net carbon gain through dark fixation their δ13C values are similar to associated non-CAM species in part because the carbon source for dark
