Behavioral Feeding Specialization In Pinaroloxias Inornata, The “Darwin's Finch” Of Cocos Island, Costa Rica, Tracey K. Werner, Thomas W. Sherry

Dartmouth Scholarship

As a population, Cocos Finches exhibit a broad range of feeding behaviors spanning those of several families of birds on the mainland, while individuals feed as specialists year-round. Although this extreme intraspecific variability occurs as predicted in a tropical oceanic island environment, these specializations challenge contemporary ecological theory in that they are not attributable to individual differences in age, sex, gross morphology, or opportunistic exploitation of patchy resources. Instead, they appear to originate and be maintained behaviorally, possibly via observational learning. This phenomenon adds another direction to the evolutionary radiation of the Darwin's Finches and underscores the necessity for detailed …

1986 (Twenty-Ninth) Fall Occurrence Report

Nebraska Bird Review

Two hundred ninety-three species (plus the possibility that the Loon sp. was not one listed) were reported from 13 "full-time" locations and 4 "spot check" locations in this report; the comparable figures for 1985 are 283 a!ld the possibility that the Empidonax species was not one listed, from 11 "full-time" and 8 "spot check" locations, 278 from 12 locations in 1984, and 262 from 10 locations in 1983.

1986 Christmas Count

Nebraska Bird Review

One hundred nine species are reported in this year's Christmas Count, eight more than last year. One species was reported present during the count week but not reported on any count, compared to two last year. Calmus-Loup made its first report this year, bringing to eleven the number of localities reporting. Fourteen species were reported on all counts; the comparable figure for. last year was also fourteen. The total individual count this year was 279,291, compared to 124,642 last year and 345,092 the year before. The Snow Goose count at DeSoto NWR and Red-winged Blackbirds and Starlings at Omaha account …

Cartographic Trend Analysis Of Furbearer Harvest Distributions In Arkansas, C. Renn Tumlison, Mark Trail, V. Rick Mcdaniel

Journal of the Arkansas Academy of Science

Average by-county fur harvest for the last nine harvest seasons (1977-1985) was used as data points to be interpolated using nearest neighbor algorithms in computer-assisted trend analyses. COMPLOT maps were produced which represented a surface of harvest densities drawn over a map of Arkansas. Twelve furbearer species are examined, and "topographic" features of harvest density for each are interpreted in terms of ecology and/or buyer distribution. The trend surface technique removed some of the error inherent to harvest records, and produced an aesthetic graphical display of the information that was more easily interpreted and explained than other methods of analysis …

The Primary Structure Of Hemoglobins Of The Adult Jaguar (Panthera Onco, Carnivora), Aftab Ahmed, Meeno Jahan, Zafar H. Zaidi, Gerhard Braunitzer, Reinhard Göltenboth

Pharmacy Faculty Articles and Research

The primary structure of the hemoglobins from Jaguar (Panthera onco) are presented. Electrophoretic separations without and with a dissociating agent revealed the presence of two hemoglobin components, OL2ß\ and a2 02. The separation of the hemoglobin components was achieved by ion-exchange chromatography. The globin chains were separated by ion-exchange chromatography and also by reversed phase HPLC. The amino-acid sequences of the native chains and peptides were determined by liquid-phase and gas-phase sequencing. N-Acetylserine was detected by FAB-mass spectroscopy as N-terminal group of the ßl chain. The sequences are compared with that of human hemoglobin (Hb A).

The Computer As A Collection Management Tool, Suzanne B. Mclaren, Hugh H. Genoways, Duane A. Schlitter

University of Nebraska State Museum: Mammalogy Papers

Since the mid-1960s, discussion of computer use for information retrieval in museum collections has usually focused on research potential. Much attention has been given to the idea of networking and the ability to access data across great distances. However, the potential for collection management usage has also proven to be a legitimate rationale for computerization. Numerous aspects of collection management are discussed for which the computer may be employed. Topics include creating cross-reference files, updating taxonomic and geographic information, pinpointing mismatched specimens, locating lost and uncataloged material, controlling loan procedures, producing accession files for insurance purposes, curating all or part …

Distribution And Current Status Of The Threatened Dismal Swamp Southeastern Shrew, Sorex Longirostris Fisheri, Robert K. Rose, Roger K. Everton, Thomas M. Padgett

Biological Sciences Faculty Publications

The Dismal Swamp southeastern shrew, Sorex longirostris fisheri, was given "Threatened" status by the U.S. Fish and Wildlife Service in 1986 because of its limited distribution and the potential threat of interbreeding with the nearby upland subspecies, Sorex l. longirostris. Known from about 20 specimens collected before 1980 and a few dozen taken since then, "fisheri" seems to have morphologically diverged from the smaller upland "longirostris" in association with the development of the Dismal Swamp. The detection of southeastern shrews that are intermediate in size between the two subspecies, coupled with the location of these collection sites on …
