We reviewed the evidence on the extent and efficacy of conservation of tropical forest biodiversity for each of the classes of conservation action defined by the new International Union for Conservation of Nature (IUCN) classification. Protected areas are the most tested conservation approach, and a number of studies show they are generally effective in slowing deforestation. There is some docu...
[1] The number of North Atlantic tropical storms lasting 2 days or less exhibits a large increase starting from the middle of the 20th century, driving the increase in recorded number of tropical storms over the past century. Here we present a set of quantitative analyses to assess whether this behavior is more likely associated with climate variability/ change or with changes in observing syst...

We provide some new local obstructions to approximating tropical curves in smooth tropical surfaces. These obstructions are based on the relation between tropical and complex intersection theories which is also established here. We give two applications of the methods developed in this paper. First we classify all locally irreducible approximable 3-valent fan tropical curves in a non-singular f...
One of the more mysterious and still rather poorly understood diseases seen in the tropical regions of the world is Tropical Sprue (TS). TS is a clinical syndrome with an unknown etiology typically characterized by an acquired chronic diarrheal illness, small bowel mucosal abnormalities and malabsorption resulting in nutritional deficiencies and weight loss [1]. These are vague symptoms which c...
