Phytogeography Of South Padre Island, Texas, Robert I. Lonard, Frank W. Judd

Biology Faculty Publications and Presentations

The phytogeographic affinities of the native flora of South Padre Island, Texas, are analyzed and the probable dispersal agent(s) for each species identified. The native flora consists of 99 species and 44% of the species also occur on the adjacent Texas mainland; 28% of the native species have tropical affinities. Only three species have probably dispersed from the island to the mainland. Two species may be endemic to Padre Island and the Tamaulipan barrier islands. Most of the tropical species have reached the island by oceanic drift, but birds are the most important dispersal agent for the native species. Man …

Cellulase Activities Of Soil Fungi, Jacobo Ortega

Biology Faculty Publications and Presentations

The cellulase activities of 8 isolates of fungi obtained from agricultural soils of Hidalgo County, TX were investigated by measuring the changes in the viscosity of a buffered solution of carboxymethylcellulose (CMC), produced by the fluids obtained from liquid cultures of these isolates. The change in the viscosity of the reaction mixture incubated at constant temperature (30 C) was measured with Cannon-Fenske routine viscometers. A buffered cellulase solution was used as a control.

Due to the variability that existed among the isolates investigated, it was possible to select active producers of cellulase with the method followed in this investigation. The …
