Current Research

In addition to continued interest in previous research areas, current research also includes an assessment of the role of tropical forests in global processes; ecological studies of tropical tree plantations; comparisons of plantations and natural forests; response of tropical forests to disturbances; studies of tropical wetlands; studies of introduced species; and the ecological characteristics of novel tropical forests including urban ecosytems.

Research Interests

Tropical forests including mangroves, forested wetlands, and urban forests; ecosystem functioning including productivity, nutrient cycling, succession, and response to natural and anthropogenic disturbances; social-ecological studies including natural processes of novelty and emerging novel ecosystems.

Past Research

Research has been conducted and published for the following ecosystems: subtropical wet forest at El Verde in Puerto Rico (1963-1966). Granite outcrops in Southeastern United States (1965-1969). Tropical wet forest at the Osa Peninsula in Costa Rica (1971). Mangrove forests of Florida (1971-1973 and 1977-1982), Puerto Rico, and the Caribbean (1973-present). Hardwood forest in Gainesville, Florida (1969-1973). Sand pine forest in Ocala, Florida (1971-1973). Río Dulce river in Guatemala (1972). Oklawaha river and floodplain wetlands in Florida (1972-1973). Farm pond in Gainesville, Florida (1970-1972). Fresh water prairie (Paynes Prairie) and associated lakes in Gainesville, Florida (1972-1975). Laboratory microcosms (1969-1975). Subtropical dry forest in Puerto Rico (1974-1977 and 1981-present). Sandhill forest in Gainesville, Florida (1976-1978). Palm wetlands in subtropical wet and subtropical rain forest life zones in Puerto Rico (1980-present).

Why This Research is Important

In the Anthropocene era (era of human domination over the world), tropical forests are more important than ever due to their biodiversity and global world. Understanding the interactions between humans and tropical forests, particularly their response and adaptation to people, becomes a vital activity if we are to maintain a healthy relationship with natural systems.
