Macroinvertebrate community of ecology of lowland, subtropical streams in Louisiana
Freshwater ecosystems, particularly streams and rivers, have been the subject of prodigious research. Unfortunately, in comparison to neighboring regions, the Gulf of Mexico coastal plain has not received as much attention. Therefore, I collected data on the macroinvertebrates of these streams to …

The agro-economic development of the lowland region of Lesotho
… the intensification of crop production in the lowland of Lesotho. The methodology used went through the following steps: a) A representative "village model" based on studies of lowland conditions was formulated. b) The alternative ways of intensifying crop production in the lowlands were …

Restoring Abandoned Agricultural Lands in Puget Lowland Prairies: A New Approach
Puget Lowland Prairies are one of the most endangered ecosystems in the United States. Restoration has been occurring for more than thirty years and has focused on extant sites with some native species present. Generally, actions first began with invasive species control, followed by reintroduction …

THE DEVELOPMENT OF DIATOM-NUTRIENT PALAEOLIMNOLOGICAL INFERENCE MODELS FOR UK LOWLAND RESERVOIRS
Deterioration of UK lowland reservoir water quality through cultural eutrophication is of concern for both water supply and conservation. This study represents the first attempt to develop diatom-based palaeolimnological inference models for the assessment of eutrophication in UK lowland …

Clarence River lowland floodplain : a morphostratigraphic analysis of a complex Holocene floodplain
The Clarence Holocene fluvio-estuarine basin is, in fact, a double basin (inner and outer) separated by a bedrock barrier which acts as a "double" protector for the inner basin against marine influences. The Clarence fluvio-estuarine basin was inundated by the Holocene sea-level transgression about …
