Phytoplankton (/ ˌ f aɪ t oʊ ˈ p l æ ŋ k t ə n /) are the autotrophic (self-feeding) components of the plankton community and a key part of oceans, seas and freshwater basin name comes from the Greek words φυτόν (phyton), meaning "plant", and πλαγκτός (planktos), meaning "wanderer" or "drifter".
Most phytoplankton are too small to be individually seen with. As much as m of land subsidence was observed in in the Houston-Galveston region as a result primarily of inelastic compaction of aquitards in the Chicot and Evangeline aquifers between and The preconsolidation pressure heads for aquitards within these two aquifers were continuously updated in response to lowering groundwater levels, which in turn was caused by continuously.

The potential for long-range transport (LRT) is a concern for synthetic chemicals of commerce, including pesticides.
Concentrations of synthetic chemicals measured at locations distant from sources, in conjunction with mass-balance modeling, have combined to provide information on key contributing processes involved in LRT, especially for persistent organic pollutants (POPs) that have.

Regime shifts are abrupt, substantial and persistent changes in the state of natural systems. Such shifts have been observed in the atmosphere (Lo & Hsu, ; Xiao et al., ), ecosystems (Hastings & Wysham, ) and human social systems (Campbell & Allen, ).Three regime shifts (s, s and s), distinguished by marked increases in temperatures or by abrupt.A detailed study during showed that fox squirrels (Sciurus niger) prefer open, mature pine/oak habitat, especially Pinus palustris/Quercus laevis, and the ecotones between pine and other vegetation types.
In summer, broadleaved and wetland forests were also important. The population biology of the squirrel and response to habitat factors are described, and its future management is.
