A Revision Of The North American Papillose Allocreadiidae (Digenea) With Independent Cladistic Analyses Of Larval And Adult Forms, Janine N. Caira

Bulletin of the University of Nebraska State Museum (1924–2023)

Adult specimens of all 19 North American species of papillose allocreadiids were examined. A description and figure is given for the adult of each species; details of the cirrus sacs are presented for most spesies for the first time. Descriptions were emended where necessary and judgments were made on synonymies. Scanning electron micrographs of the oral sucker of 10 species are presented as is a new key to the 19 species. A cladistic analysis was performed on the group based on adult characters. The analysis indicated that the group is monophyletic on the basis of the ventral papillae associated with …

The Water Vapor Conductance Of Squamate Reptilian Eggs: The Influence Of Scaling On Nesting Ecology., Louis A. Somma

Papers in Herpetology

Flexible-shelled eggs of squamate reptiles are strongly influenced by their surrounding microclimate, particularly the hydric conditions of the nest. The eggshell water vapor conductance of an egg can be an indication of its requirement for water from the nest. Ackerman et al. (1985. Physiol. Zool. 58:129-137) have described the scaling relationship for eggshell water vapor conductance (G_H2O) of flexible-shelled reptilian eggs (G_H2O = 981.8M^0.52). This scaling relationship was investigated with water vapor conductance data obtained from 8 species of lizards representing the families Iguanidae (Anolis carolinensis, A. sagrai, Sceloporus woodi, S. virgatus) …

As beads of water on the snake's head rolled down to the upper labial sceles. swallowing was observed. The water on the labial scales was drawn Into the mouth while It was closed. This behavior lasted 42 sec. This behavior was repeated 23 out of 24 trials conducted during the next 24 days. The duration of swallowing wes 9-62 sec (avg 35.8, N = …

The Bats Of Fountain Cavern, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

First paragraph:

During May 1988, two species of bats--Brachyphylla cavernarum (Antillean cave bat) and Natalus stramineus (funnel-eared bat)--were captured at the opening of Fountain Cavern. Only Brachyphylla cavernarum was captured inside of the cave. The weather was extremely wet during our visit to Anguilla so our work in Fountain Cavern was limited by hazardous conditions. Nevertheless, we did make a thorough survey of the bats inside the cave. There is only one other species on Anguilla--Monophyllus redmani (Antillean long-tongued bat)--that might be expected to utilize Fountain Cavern as a roosting site.

Includes the author's recommendations about conservation for …

Caribbean Island Zoogeography: A New Approach Using Mitochondrial Dna To Study Neotropical Bats, Carleton J. Phillips, Dorothy E. Pumo, Hugh H. Genoways, Phillip E. Ray

University of Nebraska State Museum: Mammalogy Papers

Genetic analysis of animal mitochondrial DNA is a new and valuable addition to the battery of techniques available to zoogeographers. This paper describes characteristics of mitochondrial DNA (mtDNA) that make it applicable for the study of island zoogeography.

Some traditional zoogeographic questions are examined using mtDNA from the Neotropical fruit bat, Artibeus jamaicensis. The specific questions are: 1) To what extent are island populations isolated (that is, does interbreeding occur between the insular subspecies)? 2) Can a single founding female account for the mitochondrial genomes on specific islands in the Antilles? 3) Is there a correlation between the genomic …

Lasiurus Blossevilli (Chiroptera: Vespertilionidae) In Texas, Hugh H. Genoways, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

First paragraph:

A bat netted in the ZH Canyon in the Sierra Vieja Mountains, 9 mi. W Valentine, Presidio Co., Texas, appears to be the first record of the western red bat (Lasiurus blossevillii teliotis) from the state of Texas. The specimen is an adult female that was taken on the night of 15 July 1969 by T. R. Mollhagen. The vegetation in ZH Canyon is typical low desert scrub but permanent water is present. Nets were placed in such positions as to catch bats attempting to drink at this water source.

A Monograph Of The Genus Polyphylla Harris In America North Of Mexico (Coleoptera: Scarabaeidae: Melolonthinae), Ronald M. Young

Bulletin of the University of Nebraska State Museum (1924–2023)

The North American species of the genus Polyphylla Harris, 1841, are defined and revised for the first time since Fall (1928). All name bearing types were examined except those of P. oklahomensis Hatch and P. subvittata LeConte (synonyms of P. hammondl), which are lost. A lectotype is designated for P. gracilis Horn, and neotypes for P. decemlineata (Say), P. occidentalis (L.), and P. variolosa (Hentz). New synonyms of P. decemlineata are P. comstockiana von Bloeker, P. matrona Casey, and P. potsiana Casey. New synonyms of P. crinita …

Can We Guarantee The Safety Of Genetically Engineered Organisms In The Environment?, Kathleen H. Keeler, Frances E. Sharples

School of Biological Sciences: Faculty Publications

Can we guarantee the safety of genetically engineered organisms in the environment? To anticipate my remarks, the answer to the title question is “No, we cannot guarantee the safety of genetically engineered organisms released into the environment.” Indeed, it is a tenet of the scientific method that nothing can be proved, only disproved. Thus, we can never show that a release will be safe. We could only show that it would be unsafe, if that were the case. However, if the question is posed differently, for example, can we safely release genetically engineered organisms into the environment?, the answer is …

Mitochondrial Dna Polymorphism In Three Antillean Island Populations Of The Fruit Bat, Artibeus Jamaicensis, Dorothy E. Pumo, Everett Z. Goldin, Beth Elliot, Carleton J. Phillips, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

The Neotropical fruit bat, Artibeus jamaicensis, occurs throughout Latin America and on many islands in the Caribbean. Populations from Jamaica (in the Greater Antilles) to Barbados (in the Lesser Antilles) have been classified as a subspecies (A. j. jamaicensisi separate from that on the Lesser Antillean island of St. Vincent (A. j. schwartzi). Mitochondrial DNA (mtDNA) was isolated from 54 individuals collected on these islands, analyzed by digestion with restriction endonucleases, and the restriction sites were mapped. Three different mtDNA genotypes (16,000 ± 200 bp) were identified: J-1 (16 animals from Jamaica, one from St. Vincent, …

Revised Checklist Of North American Mammals North Of Mexico, 1986, J. Knox Jones Jr., Dilford C. Carter, Hugh H. Genoways, Robert S. Hoffmann, Dale W. Rice, Clyde Jones

University of Nebraska State Museum: Mammalogy Papers

As in previous lists, orders, families, and genera are listed in conventional phylogenetic sequence mostly following Hall (1981) but, in a departure from previous lists, species are entered alphabetically within each genus. This will facilitate use of the checklist by those unfamiliar with intrageneric taxonomy. Some assemblages are not well enough understood to create a meaningful hierarchy at the specific level.

Wildlife And Nature Liberation, Michael W. Fox

Conservation Collection

Humane ethics--animal welfare--and animal rights are not incompatible with ecologically sound wildlife stewardship. They are an integral part of it, from treating wildlife for necessary research purposes humanely, to finding humane ways to control the populations of species that are out of balance and thus threatening the viability of other species and the diversity and integrity of the ecosystem. That mistakes may be made in stewardshipmanagement policies is inevitable. It is, for instance, difficult to know if the sudden abundance of one or more species and the dwindling of others is part of the natural process of succession and should …

Wildlife Conservation And Animal Rights: Are They Compatible?, Michael Hutchins, Christen Wemmer

Conservation Collection

The purpose of this paper is to explore the philosophical tenets of the animal rights/humane ethic as they relate to the environmental ethic and, more specifically, as they relate to wildlife management and conservation. The two ethics will be compared in an effort to identify potential sources of conflict. Recent criticisms of the animal rights ethic, most notably by Fox (1978, 1979), Rodman (1977), Callicott (1980), Gunn (1980), and Hutchins et al. (1982) have identified several major discrepancies. The implications of these differences will be discussed.

Classification, Paleoecology, And Biostratigraphy Of Crinoids From The Stull Shale (Late Pennsylvanian) Of Nebraska, Kansas, And Iowa, Roger K. Pabian, Harrell L. Strimple

Bulletin of the University of Nebraska State Museum (1924–2023)

Thirteen species of crinoids representing the families Diphuicrinidae, catacrinidae, Pirasocrinidae, Erisocrinidae, Cromyocrinidae, Cymbiocrinidae, Scytalocrinidae, and Ampelocrinidae have been collected from the Stull Shale Member of the Kanwaka Formation in the Shawnee Group of the Virgil Series (Upper Pennsylvanian) from near Weeping Water and Plattsmouth, Nebraska, and near Pacific Junction, Iowa. Exposures of the Stull Shale near Melvern, Kansas, have yielded 14 species of crinoids representing the families Diphuicrinidae, Catacrinidae, Pirasocrinidae, Lophocrinidae Allagecrinidae, Cymbiocrinidae, Erisocrinidae, Apographiocrinidae, and Stellarocrinidae. All but two of the species present in the Stull Shale have been previously reported from other stratigraphic horizons, including the Vinland Shale …

Fluctuations And Relationships Of Selected Physiochemical Parameters In Dardanelle Reservoir, Arkansas, 1975-1982, John D. Rickett, Robert L. Watson

Journal of the Arkansas Academy of Science

Annual and seasonal fluctuations and relationships are described for discharge, turbidity, chloride, total hardness, conductivity and suspended solids over an eight-year period in Dardanelle Reservoir. The parameters fluctuated rather widely primarily in response to seasonal patterns of rainfall. Chloride and conductivity were related and generally fluctuated together as did turbidity and suspended solids. Hardness appeared to vary independently of the others prior to 1979 then varied more closely with chloride after March 1979. Inherent differences between the Illinois Bayou arm and the main Arkansas River sections complicated the precise identification of any overall impact of power plant operation. No significant …

Notes On Maternal Behavior And Post-Brooding Aggression In The Prairie Skink, Eumeces Septentrionalis, Louis A. Somma

Papers in Herpetology

Observations of three female prairie skinks (E. septentrionalis) obtained in Omaha, NE, in 1983, including nest building, oviposition, incubation, defensive behavior, grooming of hatchlings, neonatal care, and post-brooding aggression.

Results Of The Alcoa Foundation-Suriname Expeditions. Ix. Bats Of The Genus Tonatia (Mammalia: Chiroptera) In Suriname, Hugh H. Genoways, Stephen L. Williams

University of Nebraska State Museum: Mammalogy Papers

Five species of Tonatia (bidens, brasilense, carrikeri, schulzi, and silvicola) are known to occur in Suriname. Tonatia bidens and silvicola are the largest in overall size (forearm length over 50 mm and greatest length of skull over 27.0 mm). However, T. bidens has a broader postorbital region (5.0 mm or more) and narrower mastoid region (less than 13.0 mm). The lower incisors of T. bidens are also noticeably broader than those of T. silvicola. These two species were found throughout most of the forested areas of Suriname. T. bidens displayed no secondary sexual …

Whales Are Not Cetacean Resources, Dale Jamieson, Tom Regan

Conservation Collection

What we know about whales is sufficient for ascribing to them the analogues of human rights, including the fundamental right to be treated with respect. Once we recognize their possession of this right, it follows that whales are not to be used or exploited by us for the promotion of our ends, however "benign" they may appear. In the case of humans, to refrain from killing them is to discharge only a small part of our total duties. We must also refrain from exploiting them, whether "consumptively" or "nonconsumptively." Having come as far as we have in our understanding of …

Skeleton Weed : How Serious A Threat In Western Australia?, F D. Panetta, J. Dodd

Journal of the Department of Agriculture, Western Australia, Series 4

Skeleton weed is probably the most serious weed ever to threaten the Australian wheat industry. It interferes with wheat cropping at two stages: through competition with the growing crop, particularly for nitrogen and water during the crop's development: and later through the production of a tall, wiry flowering stem which tangles in harvesting machinery and can make harvesting difficult, if not impossible.

The weed is a major problem in eastern Australia although a combination of cultural, chemical and biological control programmes is helping to reduce its impact.

In Western Australia, skeleton weed is being contained mainly by eradication efforts. Weed …

1080 : A Selective Poison For Pests, D R. King

Journal of the Department of Agriculture, Western Australia, Series 4

Since the 1960s, the control programmes for rabbits and dingoes in Western Australia have relied heavily on the use of sodium monofluoroacetate, more commonly known as compound 1080. Large quantaties are used each year as it is a valuable substance for the control of vertebrate pests.

Once in the animal's body 1080 is converted to fluorocitrate, a poison which is highly toxic to most mammals. Fluorocitrate blocks the Krebs cycle, a fundamental pathway of energy exchange in animals and plants. The animal dies as a result of damage to the heart, or to the brain and central nervous system, or …

A Checklist Of Parasites Of California, Oregon, And Washington Marine And Estuarine Fishes, Milton S. Love, Mike Moser

Harold W. Manter Laboratory of Parasitology: Faculty Publications

This report is a summary of the published records of parasites found from the marine and estuarine fishes of California, Oregon, and Washington. Coverage has not been limited to the western United States, but rather includes parasite reports from throughout each fish's range. Included is a host-parasite list and parasite-host cross index.

We have produced this survey because we felt there was a need for a single source which would list all the parasites infecting marine and estuarine fish from California, Oregon, and Washington. Pertinent sources are scattered over a number of journals, covering many years. Workers find it time …

Additional information is provided on Centronycteris maximiliana, Sigmomys alstoni, Zygodontomys brevicauda, and Cavia aperea from Suriname.

Areographic Representation Of Faunal Characteristics Through A "Second Order" Relational Approach, Charles H. Smith

DLPS Faculty Publications

Areographic analysis has traditionally depended on primary data consisting of location-specific tallies of presence or absence of given forms. In the present work, an alternate manner of representing distributions is suggested. Regional units are first established, and presence and absence of the forms under consideration in these units is noted. The relation of the biota at any given point location to all others is then established through examination of the former's characteristics of inclusion in the latter. This is accomplished by detailing regional level trends of inclusion and setting up a "second-order" distribution of associations. Two kinds of descriptive information …

The Suriname Small Mammal Survey: A Case Study Of The Cooperation Between Research And National Conservation Needs, Hugh H. Genoways, Henry A. Reichart, Stephen L. Williams

University of Nebraska State Museum: Mammalogy Papers

A cooperative program between the Foundation for Nature Preservation in Suriname and the Carnegie Museum of Natural History to survey the small mammals of Suriname is reviewed. The program has proven to be mutually beneficial and it is presented as a model for development of similar programs in the future. The technical assistance requested by the Foundation for Nature Preservation in Suriname concerned the distribution and natural history of small mammals, especially those occurring in the Nature Parks and Reserves. The Government of Suriname has established an excellent system of Reserves and Parks throughout the country. They are trying to …
