Climate Change
Climate change refers to a change in the state of the climate that can be identified (e.g., by using statistical tests) by changes in the mean and/or the variability of its properties and that persists for an extended period, typically decades or longer. Climate change may be due to natural internal processes or external forcings such as modulations of the solar cycles, volcanic eruptions and persistent anthropogenic changes in the composition of the atmosphere or in land use.
Ecological Invasion
Interspecific competition where native species are competing with nonnative species for resources (e.g., nutrients, space, water, etc.)
Nitrogen Cycle
The sequence of biochemical changes undergone by nitrogen, wherein it is used by a living organism, liberated upon the death and decomposition of the organism and converted to its original state of oxidation.

Quick Guide to Environmental Factors Impacting Subtropical and Tropical Fruit Crops in Florida
Jonathan H. Crane, Bruce Schaffer, Young Gu Her, Haimanote K. Bayabil, Jeff Wasielewski, andClyde Fraisse
Commercial tropical fruit crop acreage is expanding in Florida outside the traditional extreme south Florida and coastal counties. This largely results from the significantly warmer climate, less frequent freezing events, and less severity and duration of freezing events throughout the state, especially south-central counties. In addition, as the loss of citrus acreage continues, citrus growers and entrepreneurs are seeking alternative crops to remain in business. The successful establishment and maintenance of tropical and subtropical fruit crops in Florida depend on the crop’s tolerance to critical abiotic factors, including tolerance to flooded or waterlogged soil conditions, its ability to withstand high soil and irrigation water salinity, and its high and low temperature ranges for growth, flowering, and production. This publication aims to provide an understanding of the impacts of environmental factors on subtropical and tropical fruit crops grown in Florida.
