Herpetofaunal Inventory Of Arkansas Post National Memorial, Arkansas County, Arkansas, Malcolm L. Mccallum, Stanley E. Trauth, Robert G. Neal, Vernon E. Hoffman Jan 2003

Herpetofaunal Inventory Of Arkansas Post National Memorial, Arkansas County, Arkansas, Malcolm L. Mccallum, Stanley E. Trauth, Robert G. Neal, Vernon E. Hoffman

Journal of the Arkansas Academy of Science

The Arkansas Post National Memorial (ARPO) is a unique historical landmark with an interesting herpetofaunal community. We conducted an amphibian and reptile inventory of this national park from 2000-2002. We found eight amphibian and 21 reptilian species inhabiting the park. These included eight species not previously identified at ARPO. Overall species richness was highest at Alligator Slough, although the northern portion of ARPO was relatively rich. Aquatic trophic guilds included 7 (36.8%) piscivores, 7 (36.8%) omnivores, 4 (21.1%) insectivores, and one (5.3%) carnivore. The terrestrial trophic guilds included 13 (76.5%) insectivores, 2 (11.8%) carnivores, and 1 (5.9%) each of omnivores …

Biology Faculty Publications

The puddle frog genus Phrynobatrachus Günther, 1862 comprises about 64 currently recognized species (Frost, 1985). Of these, only the tadpoles of P. natalensis (Smith, 1849) (Power, 1927; Channing, 2001), P. guineensis Guibé & Lamotte, 1961(Rödel,1998) and P. alticola Guibé & Lamotte, 1961 (Rödel & Ernst, 2002) have been described. Phrynobatrachus mababiensis FitzSimons, 1932 (Dwarf Puddle frog, Wager, 1986; Mababe River frog, Frank & Ramus, 1996) is a small frog that usually calls from low in thick vegetation on flooded terrains close to the water. Very little has been published about the biology of this species. Passmore & Carruthers (1979) reported …

Bats Of Nevis, Northern Lesser Antilles, Scott C. Pedersen, Hugh H. Genoways, Matthew N. Morton, James W. Johnson, Siân E. Courts Jan 2003

Bats Of Nevis, Northern Lesser Antilles, Scott C. Pedersen, Hugh H. Genoways, Matthew N. Morton, James W. Johnson, Siân E. Courts

University of Nebraska State Museum: Mammalogy Papers

Only one species of bat, Molossus molossus, previously has been documented as occurring on the northern Lesser Antillean island of Nevis. Field research and reviews of existing museum collections have provided documentation based on voucher specimens for an additional seven species occurring on the island — Noctilio leporinus, Brachyphylla cavernarum, Monophyllus plethodon, Ardops nichollsi, Artibeus jamaicensis, Natalus stramineus, and Tadarida brasiliensis. The biological diversity of the chiropteran fauna on Nevis is similar to that found on other islands in the northern Lesser Antilles. Ecologically, this is a simple chiropteran fauna, including one …

Turkish Journal of Zoology

Sphaerospora elegans Thelohan, 1892 and Myxobilatus gasterostei Davis, 1944 infections in the three-spined stickleback (Gasterosteus aculeatus L., 1758) were studied from January to May 2000. Infection prevalence and intensity values were determined for mixed infections to be 26.5% and 3+ (0-5) parasites per fish, respectively. These values for each species were also determined. While infection prevalence and mean intensity values for S.elegans were 11.9% and 3+ (0-5), they were 17.9% and 3+ (0-5), respectively, for M. gasterostei. The existence of both parasite species in relation to the sex and length classes of the fish were determined and the infection interactions …

Nebraska's Sandhill Crane Population, Past, Present, And Future, Paul A. Johnsgard Dec 2002

Nebraska's Sandhill Crane Population, Past, Present, And Future, Paul A. Johnsgard

Nebraska Bird Review

Although the spring concentrations of Sandhill Cranes in Nebraska's Platte Valley are now an avian phenomenon known nationwide, a general appreciation and inventory of this unique concentration of birds has only been attempted in the last few decades. I am often asked how long this largest of all crane concentrations has been occurring in the Platte Valley, and why it has developed only there. Here I will try to summarize the little-known history of this marvelous assemblage, but not dwell on the ecological reasons for it. The latter are now generally well understood to revolve around abundant spring food supplies …

Fall Field Report, August-November 2002, W. Ross Silcock

Nebraska Bird Review

A few words on documentation of sightings reported is in order. I receive many reports each season of rare or hard-to-identify birds. If they fit a pattern that has developed over the years (see "Birds of Nebraska"), I tend to accept them as correct. However, if they fall outside the range of prior reports, I usually email the observer and ask for some details about the identification and circumstances of the sighting. Everyone has been very nice about this process; observers sometimes take these requests as a questioning of their ability, but I haven't run into this problem with Nebraska …

Individual, Temporal, And Seasonal Variation In Sperm Concentration In Tree Swallows, Michael P. Lombardo, Armetris N. Forman, Matthew R. Czarnowski, Patrick A. Thorpe Nov 2002

Individual, Temporal, And Seasonal Variation In Sperm Concentration In Tree Swallows, Michael P. Lombardo, Armetris N. Forman, Matthew R. Czarnowski, Patrick A. Thorpe

Peer Reviewed Publications

We determined sperm concentrations in Tree Swallows (Tachycineta bicolor) by manually expressing semen samples from males during prelaying, egg-laying, incubation, and nestling periods. Sperm concentrations varied by orders of magnitude (0-109 sperm mL-1) among males. Sperm concentrations were highest during the incubation period and lowest during the prelaying period. None of the samples collected during the prelaying, egg-laying, and incubation periods were devoid of sperm. In contrast, 45% of samples collected during the nestling period lacked sperm. Sperm concentrations (1) did not vary over the course of the morning during prelaying, egg-laying, and incubation periods …

The Effect Of A Predator Gradient On Female Oviposition Site Selection And Larval Performance, Josef F. Rieger Oct 2002

The Effect Of A Predator Gradient On Female Oviposition Site Selection And Larval Performance, Josef F. Rieger

Biological Sciences Theses & Dissertations

Patterns of larval amphibian distribution and abundance have historically been ascribed to direct predation. However, adult oviposition site selection is an alternative mechanism that can produce identical patterns and significantly influence community assembly. Although such behavioral habitat selection has been documented in several amphibian species whose larvae lack particular anti-predator defenses, the sensitivity of adult amphibians in detecting predator cues and avoiding these habitats has not yet been determined. If larval survivorship is greatly reduced in sites containing predatory fish, selection to detect and avoid habitats with low fish densities should be strong. I conducted three experiments which, (1) evaluated …


Hermit Warbler In Knox County: First Accepted Record For Nebraska, Mark A. Brogie Sep 2002

Hermit Warbler In Knox County: First Accepted Record For Nebraska, Mark A. Brogie

Nebraska Bird Review

The 2002 Nebraska Ornithologists' Union Record Committee has reviewed the following record and accepted it as a Class III. This Knox County sighting constitutes the first confirmed record of Hermit Warbler in Nebraska.

On 15 May, 2002, while birding with Ben Brogie, we stopped at an isolated planting of mixed hardwoods and Ponderosa Pine (Pinus ponderosa) on a high hill 5.5 miles north (Road 530) of Creighton. We noticed several birds moving among the branches along the roadside and upon "spishing" for just a few seconds we attracted a female Cape May Warbler (Dendroica tigrina) and …


The Changing Status Of Sandhill Crane Breeding In The Eastern Rainwater Basin, Joel G. Jorgensen Sep 2002

The Changing Status Of Sandhill Crane Breeding In The Eastern Rainwater Basin, Joel G. Jorgensen

Nebraska Bird Review

Prior to extirpation as a breeder before 1 900, the Sandhill Crane (Grus canadensis) formerly bred throughout Nebraska (Bruner et al. 1 904; Ducey 1988; Sharpe et al. 2001). During the 1990s, several summer observations of Sandhill Crane in the Eastern Rainwater Basin region of south-central Nebraska suggested the probability of breeding. In 1999, I discovered direct breeding evidence at Harvard Waterfowl Production Area, Clay County. This breeding record, along with another by different observers in the same county during the same season are the first modern breeding records for Nebraska. In this note, I describe my observations, …

Summer Field Report, June-July 2002, W. Ross Silcock

Nebraska Bird Review

The big news this summer was the drought which affected most of southern and western Nebraska. Conditions were particularly severe in the southern Panhandle and in the southwest. As one observer (DP) wryly noted: "The cool, cloudy weather in the sixties this morning was a welcome contrast to the stinkin' hot dirt blowing blast furnace in the low one hundreds that was in south central Nebraska Sunday afternoon [June 3]." Some comments from western Kansas by birder-rancher Scott Seltman are pertinent: "I think there's no question that because of the ongoing drought most farmers delayed their fieldwork this spring" perhaps …
