Photos from the Field: Knowledge and Experience Predict Indiscriminate Bat-Killings

Carollia perspicillata is a common, fruit-eating bat across much of Latin America, but people sometimes confuse it for a vampire bat, exacerbating human-bat conflict.

Photos from the Field: Predicting the Terminal Velocity of Dipterocarp Fruit

The first author, James Smith, prepares to release a dipterocarp fruit from a tree tower in Danum Valley, Malaysian Borneo. Dipterocarp fruit were experimentally released to measure their terminal velocities (rate at which the fruit descends through the air column). We regressed species terminal velocity against fruit wing-loading (fruit mass divided by wing area), generating a model from which terminal velocities of dipterocarp fruit can be predicted from their morphological dimensions.

Photos from the Field: Does Fire Trigger Seed Germination in the Neotropical Savannas?

Figure 2. Fire experiments conducted in wet grasslands to evaluate how fire affects vegetation composition, structure and dynamics. Local people usually burn the wet grasslands every two years in order to stimulate the production of flowering stalks of Syngonanthus nitens (“capim dourado “ - golden grass/ Eriocaulaceae), which is used in handcraft.
