From Biology To Consciousness To Morality, Ursula Goodenough, Terrence W. Deacon Dec 2003

From Biology To Consciousness To Morality, Ursula Goodenough, Terrence W. Deacon

Biology Faculty Publications & Presentations

Social animals are provisioned with prosocial orientations that operate to transcend self-interest. Morality, as used here, describes human versions of such orientations. We explore the evolutionary antecedents of morality in the context of emergentism, giving considerable attention to the biological traits that undergird awareness and our emergent human forms of mind. We suggest that our moral frames of mind emerge from our primate prosocial capacities, transfigured and valenced by our symbolic languages, cultures, and religions.

Portions of this article were given by Deacon in a paper at the forty-ninth annual conference of IRAS, “Is Nature Enough? The Thirst for …


Left-Sided Directional Bias Of Cloacal Contacts During House Sparrow Copulations, Karen B. Nyland, Michael P. Lombardo, Patrick A. Thorpe Dec 2003

Left-Sided Directional Bias Of Cloacal Contacts During House Sparrow Copulations, Karen B. Nyland, Michael P. Lombardo, Patrick A. Thorpe

Peer Reviewed Publications

Most female birds have only a left ovary and associated oviduct. The entry to the oviduct is on the left side of the urodeum of the cloaca. This arrangement may favor males that mount females from the left during copulation if it results in sperm being placed closer to the opening of the oviduct. Therefore, we predicted a left-sided directional bias of cloacal contacts during House Sparrow (Passer domesticus) copulations. Cloacal contacts from the left outnumbered those from the right 74 to 25 (3:1) during 25 bouts of copulation at 11 House Sparrow nests. While this pattern suggests …

Living On The Edge-Plants And Global Change In Continental And Maritime Antarctica, Sharon A. Robinson, J. Wasley, A. K. Tobin Dec 2003

Living On The Edge-Plants And Global Change In Continental And Maritime Antarctica, Sharon A. Robinson, J. Wasley, A. K. Tobin

Faculty of Science - Papers (Archive)

Antarctic terrestrial ecosystems experience some of the most extreme growth conditions on Earth and are characterised by extreme aridity and sub-zero temperatures. Antarctic vegetation is therefore at the physiological limits of survival and, as a consequence, even slight changes to growth conditions are likely to have a large impact, rendering Antarctic terrestrial communities sensitive to climate change. Climate change is predicted to affect the high latitude regions first and most severely. In recent decades, the Antarctic has undergone significant environmental change, including the largest increases in ultraviolet B (UV-B; 290-320nm) radiation levels in the world and, in the maritime region …

Elucidation Of The Players And Events Regulating The First Meiotic Division In Mouse Spermatocytes, Amy Lynn Inselman Dec 2003

Elucidation Of The Players And Events Regulating The First Meiotic Division In Mouse Spermatocytes, Amy Lynn Inselman

Doctoral Dissertations

Meiosis is the process that ensures the continued propagation of new organisms and is a source of genetic variability within a population. During meiotic prophase many dynamic rearrangements occur in the nucleus of the cell. These rearrangements include homologous chromosome pairing, recombination, synaptonemal complex breakdown, chromosome condensation and spindle assembly. The regulatory mechanisms behind these complex processes at the G2/MI transition have not been completely elucidated, preventing our complete understanding of the processes. The purpose of this work is to provide new insight to the events and players involved in the regulation of the G2/MI transition in mouse spermatocytes.

Another Sandhill Crane Breeding Record In The Eastern Rainwater Basin, Joel G. Jorgensen Dec 2003

Another Sandhill Crane Breeding Record In The Eastern Rainwater Basin, Joel G. Jorgensen

Nebraska Bird Review

Jorgensen (2002) recently summarized breeding-season occurrences of the Sandhill Crane (Grus canadensis) in the Eastern Rainwater Basin (eRWB). Summering birds were first detected in 1992 (The Nebraska Bird Review 60: 145). Breeding first occurred in 1994 with four additional nesting or breeding records in subsequent years. The most recent breeding records were in 1999 when breeding activity was detected at both Kissinger Basin Wildlife Management Area (WMA) (Hoffman 1999) and Harvard Waterfowl Production Area (WPA) (Silcock and Jorgensen 1999), both in Clay County. Since late 1999 the eRWB has experienced persistent drought. This has affected wetland conditions …


Chemistry Of Cirsium And Carduus: A Role In Ecological Risk Assessment For Biological Control Of Weeds?, Ingrid E. Jordon-Thaden, Svata M. Louda Dec 2003

Chemistry Of Cirsium And Carduus: A Role In Ecological Risk Assessment For Biological Control Of Weeds?, Ingrid E. Jordon-Thaden, Svata M. Louda

School of Biological Sciences: Faculty Publications

Prediction of host plant range and ecological impact of exotic phytophagous insects, such as insects for classical biological control of weeds, represents a major challenge. Recently, the flowerhead weevil (Rhinocyllus conicus Fröl.), introduced from Europe into North America to control exotic thistles (Carduus spp.), has become invasive. It feeds heavily on some, but not all species of native North American thistles (Cirsium spp.). We hypothesized that such non-target use among native plants could be better predicted by knowledge of characteristic chemical profiles of secondary compounds to supplement the results of host specificity testing. To evaluate this hypothesis, …


Case 3270: Isometrinae Clark, 1917 (Ecinodermata, Crinoidea): Proposed Emendation Of Spelling To Isometrainae To Remove Homonymy With Isometrinae Kraepelin, 1891 (Arachnida, Scorpiones), Victor Fet, Charles G. Messing Dec 2003

Case 3270: Isometrinae Clark, 1917 (Ecinodermata, Crinoidea): Proposed Emendation Of Spelling To Isometrainae To Remove Homonymy With Isometrinae Kraepelin, 1891 (Arachnida, Scorpiones), Victor Fet, Charles G. Messing

Marine & Environmental Sciences Faculty Articles

The purpose of this application, under Articles 55 and 29 of the Code, is to remove the homonymy between the crinoid subfamily name ISOMETRINAE Clark, 1917 (type genus Isometra Clark, 1908; family ANTEDONIDAE) and the scorpion subfamily name ISOMETRINAE Kraepelin, 1891 (type genus Isometrus Ehrenberg in Hemprich & Ehrenberg, 1828; family BUTHIDAE). It is proposed that the entire generic name of Isometra should be adopted as the stem, so that the correct spelling of the crinoid subfamily will become ISOMETRAINAE Clark, 1917.

Mitogenic Effect Of Bartonella Bacilliformis On Human Vascular Endothelial Cells And Involvement Of Groel, Michael F. Minnick, Laura S. Smitherman, D. Scott Samuels Dec 2003

Mitogenic Effect Of Bartonella Bacilliformis On Human Vascular Endothelial Cells And Involvement Of Groel, Michael F. Minnick, Laura S. Smitherman, D. Scott Samuels

Biological Sciences Faculty Publications

Bartonellae are bacterial pathogens for a wide variety of mammals. In humans, bartonellosis can result in angioproliferative lesions that are potentially life threatening to the patient, including bacillary angiomatosis, bacillary peliosis, and verruga peruana. The results of this study show that Bartonella bacilliformis, the agent of Oroya fever and verruga peruana, produces a proteinaceous mitogen for human vascular endothelial cells (HUVECs) that acts in a dose-dependent fashion in vitro with maximal activity at >72 h of exposure and results in a 6- to 20-fold increase in cell numbers relative to controls. The mitogen increases bromodeoxyuridine (BrdU) incorporation into HUVECs …

Fall Field Report, August-November 2003, W. Ross Silcock Dec 2003

Fall Field Report, August-November 2003, W. Ross Silcock

Nebraska Bird Review

New in this Seasonal Report, direct from the American Ornithologists' Union (along with Wilson's Snipe, Rock Pigeon, etc.), is the modified checklist order, featuring geese, swans, and ducks at the beginning, followed by gallinaceous birds, then resuming the familiar order with loons.

Perhaps the most important use for these reports, in addition to their incorporation into the Southern Great Plains Region summary in North American Birds, is the noting of significant avian events in Nebraska. Some are of obvious importance, but the meaning of others is obscure, perhaps only to be revealed as subsequent reports show a trend, or …
