Galapagos sharks (Carcharhinus galapagensis) are a large species belonging to the family Carcharhinidae, with poorly understood biology, especially along continental coastlines, which limits effective management of their populations. Here, we report preliminary findings of their movements along the Pacific Coast of Panama and Colombia, derived from satellite telemetry. Sharks were tracked for as long as 1.5 years, during which...

Leucaena leucocephala (leucaena) is an important agroforestry tree of tropics and subtropics due to its protein rich foliages, ability to grow on poor soils, and high level of tolerance to various stresses including drought and diseases. We hypothesized that leucaena have a unique set of genes which confer tolerance to various abiotic and biotic stresses and these genes are either absent or not expressed in other legumes that...

Aim The aims were: (1) evaluate the potential of Watson's framework for studying species composition in fragments and islands for a specific landscape type: cryptobiotic crust systems in the arid south‐western US; (2) expand Watson's original model to include ephemeral/non‐equilibrium systems by revising his categories of patch age and matrix contrast; and (3) examine the interplay between patch dynamics and species autecology...
