Reproduction, growth, survivorship and activity patterns in the southwestern earless lizard (Cophosaurus texanus scitulus) (phrynosomatidae) from the Big Bend region of Texas.
August 1, 2000... Abstract. -- This study reports on various aspects of reproduction, growth and survivorship in a population of the southwestern earless lizard, Cophosaurus texanus scitulus, from Big Bend Ranch State Park in west Texas (U.S.A.) over a two...

Trap-revealed microhabitat use by small mammals in monoculture grasslands.
August 1, 2000... Abstract. -- This study was conducted to determine if microhabitat differences in canopy cover of weeping lovegrass (Eragrostis curvula) monoculture grasslands influenced presence of small mammals. Canopy cover of weeping lovegrass was...

Small mammals of the Post Oak Savannah in east-central Texas.
August 1, 2000... Abstract. -- Inventory of the terrestrial vertebrate fauna at two Texas Parks and Wildlife Department sites during 1994-1995 presented the opportunity to examine the diversity of the small-mammal community of the Post Oak Savannah...

Mapping of antisense inhibition sites in the leader region of brome mosaic virus RNA 3.
August 1, 2000... Abstract. -- Antisense oligonucleotides (ASOs) are used as therapeutic agents in medicine and antisense genes are used in agriculture to modulate the gene expression in transgenic crops. One mechanism of antisense action is by interfering...

The mutagenic effects of anthracyclines in the bacterium Salmonella typhimurium: induction of transition mutations with daunomycin.
August 1, 2000... Abstract. -- This study examined the mutagenic effects of the anthracycline daunomycin in a new set of Salmonella strains. Results show that daunomycin can induce base-substitution transition mutations in Salmonella typhimurium. Specifically,...

A fossil marine turtle from east central Louisiana.
August 1, 2000... Abstract. -- A turtle carapace fragment from the well known Tunica Hills Locality, West Feliciana Parish, Louisana is referable to the marine genus Caretta. Attributed to the Citronelle Formation, its best comparisons are to a member of the...

Influence of water dynamics and land use on the avifauna of basin wetlands near Riviera in south Texas.
August 1, 2000... Abstract. -- Monthly surveys of 16 basin wetlands east of Riviera in south Texas were used to assess the importance of these wetlands to waterbirds throughout the year and to develop a conservation plan. Fifty-two bird censuses were made from...

Mortality of prairie stream fishes confined in an isolated pool.(GENERAL NOTES)
August 1, 2000... Prairie stream fishes confined to isolated pools during periods of drought are subject to highly variable abiotic conditions, which may cause physiological stress and ultimately death (Tramer 1977; Matthews et al. 1982; Mundahl 1990). There...

A new coloration in the broadhead skink, Eumeces laticeps (Sauria: Scincidae).(GENERAL NOTES)
August 1, 2000... The discovery of an undescribed color morph of Eumeces laticeps was made at the Temple-Inland Experimental Forest, located 7 km E and 4 km S of Spurger, Tyler County, Texas (30[degrees]38'45.0"N 94[degrees]04'36.0"W). Lizards were collected...

Utilization of fish as a food item by a mountain lion (Puma concolor) in the Chihuahuan Desert.(GENERAL NOTES)
August 1, 2000... Post-ingestion samples (scats, pellets) commonly have been used to determine individual food items used by wild animals. Such studies have proved valuable in learning the degree to which mountain lions (Puma concolor Linnaeus) use specific...

Noteworthy records of mammals from the Orinoco River drainage of Venezuela.(GENERAL NOTES)
August 1, 2000... The most thorough documentation of mammals found in Venezuela resulted from the Smithsonian Venezuelan project with field work occurring between 1965 and 1968 (Handley 1976). One area that was sparsely sampled, however, was the transition...

Evaluating germination protocols for Chinese tallow (Sapium sebiferum) seeds.(GENERAL NOTES)
August 1, 2000... Chinese tallow (Sapium sebiferum L. Roxb) is an exotic deciduous tree that was introduced from China into the United States in the mid-1800s (Scheld et al. 1984; Bruce et al. 1997). In Texas, tallow is expanding its range (NRCS 1993) and is a...
