Acanthocephala Of Cichlids (Pisces) In Lake Malawi, Africa, With A Description Of Acanthogyrus (Acanthosentis} Malawiensis Sp. N. (Quadrigyridae) From Labeo Cylindricus Peters, 1852 (Cyprinidae), Omar M. Amin, Sherman S. Hendrix

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Two species of acanthocephalans are reported from fishes collected during the summer of 1996 in the southeast arm of Lake Malawi (Lake Nyasa), East Africa. The common Acanthogyrus (Acanthosentis) tilapiae (Baylis, 1948) had infected 18 cichlid and 1 bagrid host species (all new host records) netted by divers wearing scuba gear around Harbor Island or caught by hook and line in deep water. The specimens of this parasite were some of the smallest ever reported for that species. Two males of a new species, Acanthogyrus (Acanthosentis) malawiensis, are described from 2 male Labeo cylindricus (Cyprinidae). This is the fifth …

Three New Species Of Eimeria From Bolivian Marsupials, S. Kimberly Heckscher, Brian A. Wickesberg, Donald Duszynski, Scott Lyell Gardner

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Faecal samples collected from 300 Bolivian marsupials (Didelphimorphia: Didelphidae) between 1984 and 1993 were examined for coccidian parasites. Sporulated oocysts were present in the faeces of 50 (17%) marsupials representing 11 genera and 22 species. Three new species of Eimeria are described and named from six host species. One species occurred in Marmosops dorothea, Monodelphis domestica and Thylamys venustus, another in Micoureus constantiae constantiae and Micoureus constantiae budini and a third in Marmosops dorothea. A discriminant analysis performed on five quantitative oocyst measurements revealed similarities between the first and third Eimeria species because of similar sizes and …

Calicotyle Californiensis N. Sp. And Calicotyle Urobati N. Sp. (Monogenea: Calicotylinae) From Elasmobranchs In The Gulf Of California, Stephen A. Bullard, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Two new species of Calicotyle (Monocotylidae: Calicotylinae) are described from elasmobranchs in the western Gulf of California. Calicotyle californiensis n. sp. is described from a single specimen collected from a gray smoothhound shark (Mustelus californicus, Carcharhiniformes: Triakidae). It is distinguished from its congeners by the combination of having vaginal pores opening within the intercecal space, distal regions of the vaginae twisting, proximal regions of the vaginae fusing medially to form a kidney bean-shaped structure, and a relatively long male copulatory organ recurving three times and passing between the distal penis bulb and the seminal vesicle.

Two-Photon Excitation Of Rhenium Metal-Ligand Complexes, Joseph R. Lakowicz, Felix N. Castellano, Ignacy Gryczynski, Zygmunt Gryczynski, Jonathan D. Dattelbaum Jan 1999

Two-Photon Excitation Of Rhenium Metal-Ligand Complexes, Joseph R. Lakowicz, Felix N. Castellano, Ignacy Gryczynski, Zygmunt Gryczynski, Jonathan D. Dattelbaum

Chemistry Faculty Publications

We describe the emission spectral properties of two rhenium metal-ligand complexes with one and two-photon excitation, Re(bpy)2(CO)3Cl and [Re(bpy)(CO)3CH3CN]+, where bpy is 2,2’-bipyridyl and CH3CN is acetonitrile. Similar emission spectra and intensity decay times characteristic of the metal-to-ligand charge transfer state were observed for one- and two-photon excitation. The lifetime and quantum yield of the acetonitrile complex are approximately 14-fold higher than that of the chloride complex. Both complexes display high anisotropies near 0.33 in frozen solution with one-photon excitation. Two-photon excitation results in anisotropies about 40% larger, …

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

There are no published records of Northern Beardless-Tyrannulet (Camptostoma imberbe) and Tropical Parula (Parilla pitiayumi) nesting in the Lower Rio Grande Valley of Texas since the late 1940s. In this 1996- 1998 study, both species were confirmed nesting at Santa Ana National Wildlife Refuge, and Northern Beardless-Tyrannulet was also confirmed at Bentsen Rio Grande Valley State Park. Most Northern Beardless-Tyrannulet nests were between clumps of ball-moss (Tillandsia recurvata) in cedar elm (Ulmus crassifolia) trees, and nests were active from 21 March-23 September. Only fe. males build nests or incubate. Two-three young fledged per successful nest, but three nests were abandoned …
