Despite the importance of tropical forest ecosystems in the global carbon cycle, there have been few studies of carbon dynamics in this biome. The magnitude of carbon stocks in the tropics and their changes over time are poorly known since ground-based observations are lacking. In this study, total carbon stocks...
The number of endangered species is rapidly increasing while paucity of adequate information and resources delays establishment of conservation actions. The IUCN’s listing system is insufficient to determine conservation priorities and many species lack information even to be evaluated (i.e., “data deficient”). Here I proposed and tested the Rapid Endangered...
The purpose of this report is to provide the IDB with the available information on the current status of aquaculture in most of its South American member countries.
Ecosystems are highly heterogeneous systems subjected to important levels of environmental variability; however, it is common in terrestrial biogeochemical models to assume homogeneous properties of the elements of the system or constant environmental conditions. For some processes, heterogeneity in these models is treated very simplistically, but there is not much...
Volcanism is an agent of major disturbance in many parts of the world. While the effects of volcanic disturbance are fairly well-known among some groups of species, few studies have been performed in bird communities. Likewise, few studies have attempted to compare how communities in temperate and tropical biomes respond...
A farm level comparative study was conducted to
determine the extend to which the production component of
the tomato industry of Panama is competitive with its
American producer counterparts in California. In addition,
processing costs, and marketing conditions/costs are factors
that determine a competitive potential. The objective of
this study...
The Central American Free Trade Agreement (CAFTA) is between the United States and Costa Rica, Nicaragua, Honduras, Guatemala, El Salvador and the Dominican Republic. CAFTA was decided in Costa Rica by a national referendum in 2007, after years of delay that left Costa Rica as the only country to have...
The coastal zone is the area where the land, sea, air meet.
It has a unique combination of characteristics which favor human
development, trade and industry.
"Coastal climates are more moderate and stable than those of
the interior of the continents, and are usually associated with
sufficient rainfall to sustain...
What historical and political reality is reflected in the novels Gringo viejo and La frontera de cristal? What is revealed when the characters, plot, and setting of the novels are analyzed against research of the context of U.S.-Mexico relations? We begin to explore these questions by studying three periods crucial...
