Origin And Evolution Of Large Brains In Toothed Whales, Lori Marino, Daniel W. Mcshea, Mark D. Uhen Dec 2004

Origin And Evolution Of Large Brains In Toothed Whales, Lori Marino, Daniel W. Mcshea, Mark D. Uhen

Veterinary Science and Medicine Collection

Toothed whales (order Cetacea: suborder Odontoceti) are highly encephalized, possessing brains that are significantly larger than expected for their body sizes. In particular, the odontocete superfamily Delphinoidea (dolphins, porpoises, belugas, and narwhals) comprises numerous species with encephalization levels second only to modern humans and greater than all other mammals. Odontocetes have also demonstrated behavioral faculties previously only ascribed to humans and, to some extent, other great apes. How did the large brains of odontocetes evolve? To begin to investigate this question, we quantified and averaged estimates of brain and body size for 36 fossil cetacean species using computed tomography and …


Apparent Sibling Rivalry In The Freshwater Clam Sphaerium Striatinum, Mark Beekey, Ronald H. Karlson Nov 2004

Apparent Sibling Rivalry In The Freshwater Clam Sphaerium Striatinum, Mark Beekey, Ronald H. Karlson

Biology Faculty Publications

In Sphaerium striatinum, a freshwater brooding bivalve, up to 97.5% of offspring that adults initially produce fail to reach independence. Marsupial sacs, specialized extensions of gill filaments that act as nurseries, initially contain multiple offspring in various sizes and stages of development. However, by the time offspring reach later stages of development, marsupial sacs typically contain only one offspring. Brood mortality is hypothesized to be the result of competition among embryos for nutrients and/or space. Sphaeriid eggs do not contain enough yolk for offspring to complete development. Adults supply additional nutrients required to reach independence. Brood capacity is limited by …


Historical Biogeography Of The Woodchuck (Marmota Monax Bunkeri) In Nebraska And Northern Kansas, Zachary P. Roehrs, Hugh H. Genoways Aug 2004

Historical Biogeography Of The Woodchuck (Marmota Monax Bunkeri) In Nebraska And Northern Kansas, Zachary P. Roehrs, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Discusses the historical biogeography of the Woodchuck (Marmota monax bunkeri) in Nebraska and northern Kansas.

First paragraph:

Jones et al. described the western limit of Marmota monax in the United States as the eastern edge of the northern Great Plains in Oklahoma, Kansas, Nebraska, and the Dakotas. Mengel introduced the idea of the Great Plains grasslands as a barrier to contact between birds of eastern and western North American forests. In his studies of bird biogeography on the Platte River, Knopf reported that this barrier has eroded with development of riparian forests along river courses of the Great …

A New Toad (Anura: Bufonidae) From Uruguay, Raúl Maneyro, Diego Arrieta, Rafael O. De Sá Jun 2004

A New Toad (Anura: Bufonidae) From Uruguay, Raúl Maneyro, Diego Arrieta, Rafael O. De Sá

Biology Faculty Publications

A new species of toad is described from small streams in the hills of Cuchilla de Haedo and Cuchilla Grande in northeastern Uruguay. Specimens of the new species were previously mistaken for Bufo arenarum; they differ from B.arenarum by having elongated parotoid glands and reddish-brown parotoid and cephalic crests. A discriminant analysis resulted in three groups corresponding to B. arenarum, Bufo rufus, and the specimens herein described as a new species.


A New Species Of Callulina (Anura: Microhylidae) From The West Usambara Mountains, Tanzania, Rafael O. De Sá, Simon P. Loader, Alan Channing Jun 2004

A New Species Of Callulina (Anura: Microhylidae) From The West Usambara Mountains, Tanzania, Rafael O. De Sá, Simon P. Loader, Alan Channing

Biology Faculty Publications

The description of the species Callulina kreffti was based on specimens collected in the East Usambara Mountains of Tanzania. Successive collecting has shown this species to be widely distributed through the Eastern Arc Mountains. Advertisement calls from populations in the type locality of Callulina kreffti were compared with calls from populations in the West Usambara Mountains. Analysis of the calls suggested that these two populations of Callulina represent two separate taxa. Subsequent morphological and molecular investigations indicated that these two populations are distinct. Herein, we describe a new Callulina species on the basis of call, morphology and molecular sequences.


Habitat Preferences Of Four Species Of Lizards Found At The Las Vegas Springs Preserve, Scott Garncarz May 2004

Habitat Preferences Of Four Species Of Lizards Found At The Las Vegas Springs Preserve, Scott Garncarz

UNLV Theses, Dissertations, Professional Papers, and Capstones

Developing an understanding of the habitat usage of reptiles is important when trying to develop a management or restoration plan that is compatible with what is known of the reptile species that are being investigated. There are many lizard species found in the Mojave Desert, but there are only four known to inhabit the Las Vegas Springs Preserve (LVSP) in Las Vegas, Nevada. In the LVSP, sites are going to be restored with native Mojave Desert vegetation. Since there are many habitat types in the Mojave Desert, we must determine which types would be best suited for the four species …

A New Subspecies Of Cicindela Nevadica Leconte (Coleoptera: Carbidae: Cicindelinae) From The Badlands Of South Dakota, Stephen M. Spomer Jan 2004

A New Subspecies Of Cicindela Nevadica Leconte (Coleoptera: Carbidae: Cicindelinae) From The Badlands Of South Dakota, Stephen M. Spomer

University of Nebraska State Museum: Entomology Papers

A new subspecies of Cicindela nevadica LeConte, Cicindela nevadica makosika Spomer, is described from the South Dakota Badlands. Geographically, the population occurs at the periphery of the range of C. nevadica knausii Leng. However, this new population is geographically isolated from the nearest C. n. knausii populations, which occur ca. 100 air miles north and over 100 air miles south. Phenotypically, C. n. makosika appears most similar to C. n. tubensis Cazier from northeast Arizona. A possible threat to this population is habitat destruction by cattle.

Unusual Behavior By Bison, Bison Bison, Toward Elk, Cervus Elaphus, And Wolves, Canis Lupus, L. David Mech, Rick T. Mcintyre, Douglas W. Smith Jan 2004

Unusual Behavior By Bison, Bison Bison, Toward Elk, Cervus Elaphus, And Wolves, Canis Lupus, L. David Mech, Rick T. Mcintyre, Douglas W. Smith

USGS Northern Prairie Wildlife Research Center

Incidents are described of Bison (Bison bison) in Yellowstone National Park mauling and possibly killing a young Elk (Cervus elaphus) calf, chasing wolves (Canis lupus) off Elk they had just killed or were killing, and keeping the wolves away for extended periods. During one of the latter cases, the Bison knocked a wolf-wounded Elk down. Bison were also seen approaching wolves that were resting and sleeping, rousting them, following them to new resting places and repeating this behavior. These behaviors might represent some type of generalized hyper-defensiveness that functions as an anti-predator strategy.

Distribution, Habitat Use, Growth, And Condition Of A Native And An Introduced Catfish Species In The Hudson River Estuary, Stephen M. Jordan, Robert M. Neumann, Eric T. Schultz

EEB Articles

White catfish (Ameiurus catus) is native to the Hudson River and is now coexisting with the recently established channel catfish (Ictalurus punctatus). These species were sampled from four freshwater reaches and four habitat types of the Hudson River estuary to assess whether the two species overlapped in their habitat use, and whether any impact on the native species was evident. Catfishes were sampled in 1998 and 1999 using baited hoop nets (N = 708 net nights). Catch-per-unit-effort (CPUE, number of fish per net night; total catch = 368) of white catfish was significantly different among reaches …


Limulus In The Limelight: Exploring An Ancient Species, John Tanacredi Ph.D. Jan 2004

Limulus In The Limelight: Exploring An Ancient Species, John Tanacredi Ph.D.

Faculty Works: CERCOM

In an era when sports numbers shatter historical ceilings (especially in baseball) and fall by the wayside like fall leaves, a most enduring record of life continues to crawl along emerging from the sea early each spring pronouncing their incredible "record" of existences... over 350 million years. Now there is a number that even the rarified air of baseball salaries can admire. Yet, today the remarkable sea creature which endured over 100 million years of dramatically changing earth history prior to the existence of the dinosaurs, and which is comprised of only four species globally, is being tested for its …


Ichthyofaunal And Dietary Analysis Of Sympatric Piscivores In A Chesapeake Bay Littoral Zone: Including Bioenergetic Models Of Growth And Diel Temperature Sanctuary Use, Christian Harding Hager Jan 2004

Ichthyofaunal And Dietary Analysis Of Sympatric Piscivores In A Chesapeake Bay Littoral Zone: Including Bioenergetic Models Of Growth And Diel Temperature Sanctuary Use, Christian Harding Hager

Dissertations, Theses, and Masters Projects

The first section of this dissertation describes the ichthyofaunal community of a mesohaline Chesapeake Bay April--November. Fish assemblages were sampled using two seine gears, a small seine that sampled 352 m 2 and a 914m haul-seine that sampled 144,473 m2. The small seine collected 32 finfish species. The larger gear captured 31 finfish species, including 17 that were not sampled by small gear. Sampled diversity was greater but density estimates were similar to those determined previously by other investigators using flume-net, drop-ring, and otter trawl techniques. Nocturnal abundance of larger fishes far exceeded daylight. Fish abundance and size distribution varied …


The Effect Of Size-Limited Brood Capacity On Brood Size In A Freshwater Bivalve, Mark Beekey Jan 2004

The Effect Of Size-Limited Brood Capacity On Brood Size In A Freshwater Bivalve, Mark Beekey

Biology Faculty Publications

Size limited brood capacity is common among species with hard exoskeletons or shells. In these species, brood size is limited by the physical capacity to hold offspring. Here we present evidence that brood size is limited by physical constraints in Sphaerium striatinum , a small brooding bivalve. Sphaerium striatinum is a sequential brooder and produces offspring throughout the year. Offspring are brooded in marsupial sacs located on the inner demibranch. In an unconstrained brooder one would predict that brood size would increase as a function of adult length cubed, a volumetric relationship. In S. striatinum, brood size increases as less …


On The Cranial Anatomy Of The Polycotylid Plesiosaurs, Including New Material Of Polycotylus Latipinnis, Cope, From Alabama, F. Robin O’Keefe Jan 2004

On The Cranial Anatomy Of The Polycotylid Plesiosaurs, Including New Material Of Polycotylus Latipinnis, Cope, From Alabama, F. Robin O’Keefe

Biological Sciences Faculty Research

The cranial anatomy of plesiosaurs in the family Polycotylidae (Reptilia: Sauropterygia) has received renewed attention recently because various skull characters are thought to indicate plesiosauroid, rather than pliosauroid, affinities for this family. New data on the cranial anatomy of polycotylid plesiosaurs is presented, and is shown to compare closely to the structure of cryptocleidoid plesiosaurs. The morphology of known polycotylid taxa is reported and discussed, and a preliminary phylogenetic analysis is used to establish ingroup relationships of the Cryptocleidoidea. This study also presents new material referable to Polycotylus latipinnis from the Mooreville Chalk Formation of Alabama. This skeleton is largely …
