dc.description.abstract | Eleven collection dates were used to sample the
population density of corixids in three lake types found on
the Southern High Plains of Texas from June 1990 to August
1991. Lakes were designated feedlot, saline, and vegetated
according to visual categorization. Abiotic and biotic
environmental parameters were sampled in each lake to
determine if correlations exist between these parameters and
the corixid species population density observed. The
parameters measured were turbidity, nitrogen, salinity, and
number of plant stems. Seven species of corixids were found
during the study. Corisella edulis, Corisella tarsalis and
Sigara alternata were well-established in feedlot and
vegetated lakes, whereas Trichocorixa reticulata and
Trichocorixa verticalis were found in great abundance in
saline lakes. Few significant differences were found between
the parameters measured and the density of any of the corixid
species found in these lakes. Cluster analysis showed that
the feedlot lakes were most similar to each other both in
species density and the correlation of these species with the
measured parameters. | |
