He was a past chair of the Scientific Technical Advisory Panel (STAP) for the Global Environment Facility (GEF), the multibillion-dollar funding mechanism for developing countries in support of their obligations under international environmental conventions.
Barro Colorado Island is located in the man-made Gatun Lake in the middle of the Panama Canal. The island was formed when the waters of the Chagres River were dammed to form the lake in 1913. When the waters rose, they covered a significant part of the existing tropical forest, but certain hilltops remained as islands in the middle of the lake. It has an area of 15.6 km2 (6.0 sq mi).
A liana is a long-stemmed woody vine that is rooted in the soil at ground level and uses trees, as well as other means of vertical support, to climb up to the canopy in search of direct sunlight. The word liana does not refer to a taxonomic grouping, but rather a habit of plant growth – much like tree or shrub. It comes from standard French liane, itself from an Antilles French dialect word meaning to sheave.
The sun bear is a species in the family Ursidae occurring in the tropical forests of Southeast Asia. It is the smallest bear species, standing nearly 70 cm (28 in) at the shoulder and weighing 25–65 kg (55–143 lb). It is stockily built, with large paws, strongly curved claws, small, rounded ears and a short snout. The fur is generally short and jet black, but can vary from grey to red. The sun bear gets its name from its characteristic orange to cream-coloured chest patch. Its unique morphology—inward-turned front feet, flattened chest, powerful forelimbs with large claws—suggests adaptations for climbing.
The 1958 Atlantic hurricane season included every tropical cyclone either affecting or threatening land. There were ten named storms as well as one pre-season tropical storm. Seven of the storms became hurricanes, including five that were major hurricanes, or the equivalent of a Category 3 on the Saffir-Simpson scale. The strongest storm was Hurricane Helene, which became a strong Category 4 hurricane with 150 mph (240 km/h) winds and a barometric pressure of 930 millibars (27 inHg) while just offshore the southeastern United States.
Capsicum annuum var. glabriusculum, a chili-pepper variety of Capsicum annuum, is native to southern North America and northern South America. Common names include chiltepín, Indian pepper, grove pepper, chiltepe, and chile tepín, as well as turkey, bird’s eye, or simply bird peppers. Tepín is derived from a Nahuatl word meaning "flea". This variety is the most likely progenitor of the domesticated C. annuum var. annuum. Another similar-sized pepper, 'Pequin' is often confused with tepin, although the tepin fruit is round to oval where as the pequin's fruit is oval with a point, and the leaves, stems and plant structures are very different on each plant.
The Smithsonian Tropical Research Institute is located in Panama and is the only bureau of the Smithsonian Institution based outside of the United States. It is dedicated to understanding the past, present, and future of tropical ecosystems and their relevance to human welfare. STRI grew out of a small field station established in 1923 on Barro Colorado Island in the Panama Canal Zone to become one of the world's leading tropical research organizations. STRI's facilities provide for long-term ecological studies in the tropics and are used by some 1,200 visiting scientists from academic and research institutions around the world every year.
The Smithsonian Conservation Biology Institute (SCBI) is a unit of the Smithsonian Institution located on a 3,200-acre (13 km2) campus located just outside the town of Front Royal, Virginia. An extension of the National Zoo in Washington, D.C., the SCBI has played a leading role in the fields of veterinary medicine, reproductive physiology and conservation biology since its founding in 1974.
Seed predation, often referred to as granivory, is a type of plant-animal interaction in which granivores feed on the seeds of plants as a main or exclusive food source, in many cases leaving the seeds damaged and not viable. Granivores are found across many families of vertebrates as well as invertebrates ; thus, seed predation occurs in virtually all terrestrial ecosystems.

The Ngel Nyaki Forest Reserve, whose site is historically known as Majang, is situated on the Mambilla Plateau in North East Nigeria, covering 46 km2. It can be reached on foot from Yelwa village past the Mayo Jigawal, from where it is less than half an hour’s walk to the upper edge of the forest. The elevation ranges from 1,400 metres (4,593 ft) to 1,600 metres (5,249 ft). Ngel Nyaki was formally gazetted a local authority Forest Reserve under Gashaka - Mambilla Native Authority Forest order of April 1969, but presently it is under the management of the Taraba State Government and the Nigerian Conservation Foundation (NCF), with the Nigerian Montane Forest Project (NMFP) as a project partner.
