Distribution And Abundance Of Anopheles Spp. In The Lower Rio Grande Valley, South Texas, Norma Hermelinda Martinez
Distribution And Abundance Of Anopheles Spp. In The Lower Rio Grande Valley, South Texas, Norma Hermelinda Martinez
Theses and Dissertations - UTB/UTPA
This study investigated the relationship between Anopheles abundance, collection sites and environmental variables in the Lower Rio Grande Valley, South Texas. In addition, species composition in the Lower Rio Grande Valley was determined in 2011. A total of 6772 female mosquitoes were identified to six genera and 27 species. The most prevalent genera collected were Culex (53.9%), Ochlerotatus (25.6%) and Aedes (13.6%). Anopheles mosquitoes were collected using resting boxes during summer 2012 at multiple locations along the Lower Rio Grande Valley. ArcGIS was used to identify land cover characteristics and nearest water sources at mosquito collection sites. Estero Llano Grande …
A Comparison Of Site Fidelity And Habitat Use Of Red Snapper (Lutjanus Campechanus) To Evaluate The Performance Of Two Artificial Reefs In South Texas Utilizing Acoustic Telemetry, Andres Garcia
Theses and Dissertations - UTB/UTPA
Evaluation of artificial reefs is becoming an increasingly important component of fisheries management. This is particularly true for the northwestern Gulf of Mexico where natural hard substrate is limited and 359 petroleum platforms are scheduled for removal in 2013 due to the “idle iron” policy. This study compared the performance of two artificial reef configurations off the south Texas coast, the Texas Clipper and South Padre Island Near Shore Reefs that differ in material, depth, and distance from shore, with respect to behavior of red snapper, Lutjanus campechanus, an important recreational and commercial species. Red snapper were implanted with depth …
Effects Of Habitat Enrichment On The Stress Level Of The Sit-And-Wait Predator Sand Boa (Gongylophis Colubrinus), Jose Manuel Cantu Martinez
Effects Of Habitat Enrichment On The Stress Level Of The Sit-And-Wait Predator Sand Boa (Gongylophis Colubrinus), Jose Manuel Cantu Martinez
Theses and Dissertations - UTB/UTPA
Conditions in which the animals are housed vary according to animal use. Conditions unfamiliar or unsuited to organisms usually induce stress. Stress is mirrored by a hormone cascade resulting in glucocorticoids. Of the glucocorticoids corticosterone is regarded as the most important. The corticosterone levels of sand boas (Gongylophis colubrinus) were measured under enriched and barren soil and cage features. Enriched soil consisted of enough dirt to allow borrowing. Enriched cage featured consisted of a wooded ball. Barren soil consisted of newspaper as substrate. Barren cage features consisted of plane newspaper. Snakes were subject to treatment for two weeks. No significant …
