Although most conservation efforts focus on preserving biodiversity in relatively pristine ecosystems, we investigated possible conservation opportunities in human-dominated landscapes. We evaluated butterfly diversity in a tropical countryside that was converted about four decades ago from continuous forest to a mosaic of coffee farms, pasture, and forest fragments. We compared the butterfly f...

We observed the mating behavior of the neck-banded snake Scaphiodontophis annulatus (a common species of colubrid in the South Pacific of Costa Rica) in the pre-montane wet forest of Las Cruces Biological Station (San Vito de Java, Costa Rica).

Nowadays, organic fertilizers play an important role in agriculture. They are progressively substituting chemical fertilizers to prevent their harmful impact on human health and the environment. They provide high yield, better quality products and a shorter period of harvesting crops. In this study, the mineral elements: primary macronutrient (N, PO3- and K+), secondary macronutrient: (Ca2+, Mg...
