These birds were originally collected and mounted by Sammy Ray between 1937 and 1940. Those are slide 2-8; slides 9-31 are of birds and circumstances of collecting in the Pacific theater of World War II (1943-1945) while Dr. Ray was serving in the U.S. Arm

The development of a hyperbaric reactor for the biological oxidation of a colloid
No full textIn order to investigate limitations in a mechanism for biological oxidation of colloids, an experimental scheme was derived. The system employs the use of (1) cell disruption by high frequency sound to facilitate hydrolysis through increased enzyme activity and (2) oxygen enrichment using a hyperbaric reactor to support the anticipated oxygen demand of increased biological solids. The study objectives are concerned with (1) comparison of hydrolysis rates in a disrupted and undisrupted system, (2) comparison of hydrolysis product removal rates in a pressurized and unpressurized system, (3) optimum process operation for starch degradation. Assayed are the rate processes of oxygen uptake, solids growth, hydrolysis, and substrate uptake. A hyperbaric reactor of 3.38 liter capacity was constructed from plexiglass tubing. Included were provisions for a flow control valve, pressure gauge, sample port, oxygen probe and internal air spargers. Compressed air was fed to the reactor through copper tubing and controlled by a flow meter. Operating pressures were typically 1, 2, 3, 4 and 4.8 atm. ..
A study of the zooplankton assemblage of San Antonio Bay, Texas, and of the effects of river inflow on the composition and the persistence of this assemblage
No full textVita.The composition and abundance of the zooplankton community in San Antonio Bay were studied. Particular attention was paid to the occurrences and densities of selected taxa and to the effects of floods on this zooplankton community. Samples were collected twice per month over a 29-month period from March 1972 through July 1974. Each sample consisted of a one-minute oblique tow using a #10 mesh conical nylon net having a half-meter diameter mouth fitted with a flowmeter. A total of 279 taxa belonging to groups such as protozoans, rotifers, cladocerans, copepods, decapod zoeae, insect larvae, and fish larvae were identified from the 568 samples analyzed. This zooplankton community contained species and taxa which were typical of most Texas estuaries and which represented an indicator group. These were: Acartia tonsa, Pseudodiaptomus coronatus, Paracalanus crassirostris, Oithona colcarva, Copepod nauplii, Balanus spp. nauplii and cyprids, Gastropod veligers, Bivalve veligers, Cyphonautes larvae, and Polychaete larvae. During floods several freshwater species and taxa became abundant in the bay. These were: Arcella discoides, Brachionus calyciflorus and B. quadridentatus, Moina micrura, Diaphanosoma brachyurum, Diaptomus spp., Cyclops spp., Eucyclops agilis, and several insect larvae. The seasonal abundance of zooplankton (all-inclusive) varied each year of the study. It was highest during the first 12 months. Maxima occurred in late winter or early spring when Balanus spp. nauplii rose to 100,000/m^3 at several sites. A smaller peak occurred during the summer due to Acartia tonsa populations which rose to 35,000/m^3 at several sites during the summer of 1972. Floods caused total zooplankton densities to decrease between one and two orders of magnitude in all zones. Zooplankton densities were unable to regain initial values after the first flood in 1973, and they decreased more and more with each successive flood. Only when river flow rates returned to less than 100 m^3/sec could the typical estuarine indicator group return to dominance. The recovery period was from two weeks to two months for the lower bay and the upper bay respectively. The return to dominance of the estuarine indicators was predominantly due to importation of large populations of these taxa with influxes of saline water from Espiritu Santo Bay..
A survey of the occurrence, distribution and incidence of infection of helminth parasites of marine and estuarine mollusca from Galveston, Texas
No full textThe results of a 3-year study of the helminth parasite fauna of the marine Mollusca of the Galveston Bay, Texas area are presented, including data on morphology, behavior, ecology, systematics and life cycles of the parasites, and their effects upon their molluscan hosts. Three species of Turbellaria, 34 species of digenetic Trematoda, eight species of Cestoda and one species of Nematoda were found among the 12,131 individual molluscs examined. Most of the parasites are identifiable with previously-described species, but five species of larval digenetic trematodes appear to be significantly different from known forms and may represent new species. These include a tail-less fellodistomatid cercaria, a trichocercous fellodistomatid cercaria, a renicolid xiphidiocercaria, a cercariaeum which encysts in its own redia, and a setose cystophorous appendiculate cercaria of the family Hemiuridae. The three turbellarians appear to utilize no other host in their life cycle. Of the 34 trematode species, 18 resemble species whose adult forms are parasites of warm-blooded aquatic vertebrates and 16 appear to be related to species whose adult forms are parasites of marine fishes. The eight cestode larvae are all forms whose adult stages occur in the gut of elasmobranch fishes, and the single nematode larva probably utilizes marine teleost fishes as hosts for the adult stage
