Os trópicos úmidos brasileiros caracterizam-se por médias anuais de temperaturas em torno 25ºC e índices pluviométricos entre 1.250 mm a 2.000 ocorrem, principalmente, no litoral oriental do Brasil. Tais características climáticas se associam acelerados mecanismos meteorização rochas, solos e, consequentemente, levando à remoção intensa material superfície e/ou subsuperfície.

Tropical Australia. Streams and rivers of the Australian tropics have been subject substantial hydrological process research spanning last 50 years. In this review, we highlight initial efforts to understand response forested ecosystems in humid tropics, how has more recently followed by work savannas seasonal tropics. We describe recent findings from modelling tracer studies derive a framework...

Tropical forests are experiencing a growing fire problem driven by climatic change, agricultural expansion and forest degradation. Protected areas are an important feature of forest protection strategies, and sustainable use reserves (SURs) may be reducing fire prevalence since they promote sustainable livelihoods and resource management. However, the use of fire in swidden agriculture, and oth...

Background: We deciphered thermoregulatory activities of exotic breeds of rabbit in the event of least thermal discomfort in Ibadan, Nigeria. This investigation was carried out between July and August during the least temperature-humidity index (THI). Twenty bucks and 14 doe per breed, housed individually and randomly assigned to experimental units in a completely randomized design, were used f...
