Hispid Cotton Rat - Plant Communities

Plant Communities

Hispid cotton rats occur in mesquite (Prosopis spp.) bosques in Arizona and New Mexico. On the Coastal Plain, hispid cotton rats occupy the periphery of central ponds and more distant ecotonal areas of baldcypress (Taxodium distichum) swamps. Hispid cotton rats are abundant in fallow rice fields in Texas, primarily near heavily overgrown canalbanks and levees.

In Florida, hispid cotton rats are common in sabal palm (Sabal palmetto)-coconut palm (Cocos nucifera) savanna. In the Southeast, hispid cotton rats prefer grassy understories of fire-maintained loblolly pine (Pinus taeda)-shortleaf pine (P. echinata) and longleaf pine (P. palustris)-slash pine (P. elliottii) stands.

In Florida, sand pine (P. clausa) scrub has been invaded by hispid cotton rats for short periods. Reasons for the invasion were not clear but were probably related to increased population densities in nearby optimum habitat (pine flatwoods with a dense ground cover of grasses and herbs). Sand pine scrub has little ground cover and is marginal habitat for hispid cotton rats.

Famous quotes containing the words plant and/or communities:

    The North American system only wants to consider the positive aspects of reality. Men and women are subjected from childhood to an inexorable process of adaptation; certain principles, contained in brief formulas are endlessly repeated by the press, the radio, the churches, and the schools, and by those kindly, sinister beings, the North American mothers and wives. A person imprisoned by these schemes is like a plant in a flowerpot too small for it: he cannot grow or mature.
    Octavio Paz (b. 1914)

    Culture is the name for what people are interested in, their thoughts, their models, the books they read and the speeches they hear, their table-talk, gossip, controversies, historical sense and scientific training, the values they appreciate, the quality of life they admire. All communities have a culture. It is the climate of their civilization.
    Walter Lippmann (1889–1974)
