Correction to the 2001 (13th) Report of the NOU Records Committee

Joel Jorgensen reports that the photo of the White Ibis mentioned in the 13th NOURC Report (NBR 71: 98) was taken at Johnson WPA 19 Aug, not Funk WPA. The bird was originally discovered at Funk WPA on 9 Aug, and then it presumably moved to Johnson WPA 12-19 Aug. See Silcock, W.R., "Fall Field' Report, August-November 2001".

In Memory Of George W. Brown, Neal Ratzlaff

Nebraska Bird Review

NOU member, supporter and friend George Brown passed away on February 9, 2002, at the age of 80 following a 10 year battle with leukemia.

His many contributions to this organization include service as President on two occasions, 1974-5 and 1992-4. Some of us remember smaller but equally memorable contributions, including the flower arrangements, gifts from George's garden, that appeared on the tables at our Halsey Fall Field Days; his wonderful stories and good humor; his personal thriftiness which he applied with equal vigor to the NOV budget; and his love of only the most brief and concise presentations. The …


Spring Field Report, March-May 2004, W. Ross Silcock Jun 2004

Spring Field Report, March-May 2004, W. Ross Silcock

Nebraska Bird Review

This was a fairly typical spring with wide variations in temperature, although severe storms May 22 and 24 caused considerable damage to property and presumably nesting birds; dead robins and their blown-down nests were ubiquitous.

There continues to be an accumulation of observations indicative of earlier arrival of some species as well as possibly related range expansion northward of others (see species accounts for details). Notably early were most of the swallow species, Long-billed Curlew, and Bobolink. Northward range expansion seems to be occurring with Scissor-tailed Flycatcher, Hooded Warbler, and Summer Tanager. Numbers of Piping Plovers and Snowy Plovers at …

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.


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.

Extinction is a natural process. Today, however, plant and animal species are disappearing world-wide at an accelerated pace. Based on current trends, half of the species on earth will be extinct within the next 100 years. The major cause of this phenomenon is large-scale destruction of native habitats, which has increased since European settlement began in the mid 1800's - in Oregon and throughout the New World.

Once lost, a species can never be recovered, and there is no way of knowing how useful it may have been. We do know that human beings and many of their industries depend …

Eurasian Collared-Dove (Streptopelia Decaocto) Expnasion In Nebraska: 1997-2003, Mark A. Brogie, W. Ross Silcock Mar 2004

Eurasian Collared-Dove (Streptopelia Decaocto) Expnasion In Nebraska: 1997-2003, Mark A. Brogie, W. Ross Silcock

Nebraska Bird Review

Following the recognition of its presence in Florida in the mid-1980s (Smith and Kale 1986), the Eurasian Collared-Dove has spread in spectacular fashion northward and mostly westward in the interior of the United States, arriving in Nebraska only about 15 years after its discovery in Florida. Prior to its establishment in the United States, the Eurasian Collared-Dove had undergone a similarly spectacular expansion westward across Europe beginning in the area of Albania and the former Yugoslavia in the 1930s and finally colonizing Great Britain in the late 1950s. Available evidence regarding the source population for its establishment in Florida points …

2003 Christmas Bird Counts In Nebraska Mar 2004

2003 Christmas Bird Counts In Nebraska

Nebraska Bird Review

There were 11 Christmas Bird Counts conducted in Nebraska in December of 2003. One (the DeSoto National Wildlife Refuge count) is partly in Iowa. The total of 132 species recorded is 5 fewer than last year's total of 137. This year 222,405 individuals were counted, as compared to the unusually high individual count of 303,619 in 2002, largely because of Snow Goose numbers. In 2002, 129,415 Snow Geese were reported, compared to this year's report of 10,940. There were 16 species which were seen on every count: Bald Eagle, Red-tailed Hawk, American Kestrel, Ring-necked Pheasant, Rock Pigeon, Downy Woodpecker, Northern …

New Editor For The Nebraska Bird Review

Nebraska Bird Review

On behalf of the Nebraska Ornithologists' Union, I would like to take this opportunity to announce a change in The Nebraska Bird Review. Dr. Bill Clemente, Professor of English at Peru State College, has resigned as Editor, due to increasing demands on his time from his teaching and research and his family in Wisconsin. His resignation is accepted with regrets, for he has served the publication ably since he took over the job from Rosalind Morris at the beginning of 1998. We thank Dr. Clemente for his years of service and wish him well in the future.

Winter Field Report, December 2003 To February 2004, W. Ross Silcock Mar 2004

Winter Field Report, December 2003 To February 2004, W. Ross Silcock

Nebraska Bird Review

Last year, I wrote: "Overall, this was a pretty quiet winter season. There were no major weather events, no major invasions (just one minor incursion), and, with one big exception, no real rarities." This is pretty much true of this winter too, except that there weren't even any minor incursions, unless Common Redpoll and Purple Finch qualify, and no drop-dead rarities, although Black-headed Gull comes close! In fact, we returned to a fairly normal type of winter with some cold weather and accumulating snow cover. This caused birds to leave in fall in normal fashion, and, in general, to arrive …

Cheloniidae (Marine Turtle) Nest Predation, John Woolard, Richard M. Engeman, Henry T. Smith, John Griner Feb 2004

Cheloniidae (Marine Turtle) Nest Predation, John Woolard, Richard M. Engeman, Henry T. Smith, John Griner

United States Department of Agriculture Wildlife Services: Staff Publications

On 19 June 2003 at 0217 h, an opossum (Didelphis virginiana) was observed for 10 min while digging into a marine turtle nest and eating 4 eggs on the beach at St. Lucie Inlet Preserve State Park (SLIPSP) on Jupiter Island, Florida. The predation event was observed using night vision equipment as part of nightly patrols to protect turtle nests from raccoon (Procyon lotor) and armadillo (Dasypus noverncinctus) predation during the nesting season. After verification of an ongoing predation event, the opossum was euthanized and removed. Prior to implementing predator removal on this beach, …


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.


Agroforestry, Elephants, And Tigers: Balancing Conservation Theory And Practice In Human-Dominated Landscapes Of Southeast Asia, Philip J. Nyhus, R L. Tilson Jan 2004

Agroforestry, Elephants, And Tigers: Balancing Conservation Theory And Practice In Human-Dominated Landscapes Of Southeast Asia, Philip J. Nyhus, R L. Tilson

Faculty Scholarship

Large mammal populations theoretically are best conserved in landscapes where large protected areas are surrounded by buffer zones, connected by corridors, and integrated into a greater ecosystem. Multi-use buffer zones, including those containing complex agroforestry systems, are promoted as one strategy to provide both economic benefits to people and conservation benefits to wildlife. We use the island of Sumatra, Indonesia to explore the benefits and limitations of this strategy. We conclude that conservation benefits are accrued by expanding the habitat available for large mammals but more attention needs to be focused on how to reduce and respond to human–wildlife conflict …


Minnesota Banded Darters (Etheostoma Zonale) Exhibit A High Degree Of Genetic Similarity In Mitochondrial Dna Sequences Occurrence, Jean Porterfield, Molly Fee, Jessica Theorin Jan 2004

Minnesota Banded Darters (Etheostoma Zonale) Exhibit A High Degree Of Genetic Similarity In Mitochondrial Dna Sequences Occurrence, Jean Porterfield, Molly Fee, Jessica Theorin

Journal of the Minnesota Academy of Science

Hylogeography, or the historical interpretation of population genetic data, is a useful tool for addressing historical processes like the colonization history of organisms. North American freshwater fishes have experienced glacial ebb and flow in their relatively recent past (as little as 10,000 years before present in Minnesota), and studies of variation in intraspecific DNA sequences of these fishes can shed light on their radiations into previously glaciated areas. This study assessed intraspecific variation in two mitochondrial genes of the banded darter (Etheostoma zonale) from seven Minnesota localities. A high degree of similarity was found among all individuals in the study. …


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 Jan 2004

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 …


Hatching Asynchrony, Survival, And The Fitness Of Alternative Adult Morphs In Ambystoma Talpoideum, Travis J. Ryan Jan 2004

Hatching Asynchrony, Survival, And The Fitness Of Alternative Adult Morphs In Ambystoma Talpoideum, Travis J. Ryan

Scholarship and Professional Work - LAS

The mole salamander, Ambystoma talpoideum, exhibits both aquatic (gilled) and terrestrial (metamorphosed) adult morphologies. Previous studies have shown the existence of body-size advantages associated with the terrestrial morph in A. talpoideum and other polymorphic salamanders (e.g., A. tigrinum). However, aquatic adult A. talpoideum mature at a younger age and often breed earlier than terrestrial adults. We tested the hypothesis that early maturation and reproduction in aquatic adults increase fitness (irrespective of body size). We reared larval A. talpoideum in mesocosms and varied the timing of hatching, with early-hatching larvae representing the offspring from early-breeding aquatic adults, and late-hatching larvae representing …


Investigation Into The Use Of Bait Stations For The Control Of The European Wild Rabbit (Oryctolagus Cuniculus) In The Urban Bushland Reserve Of Bold Park, Perth, Western Australia, Malin Kordes Jan 2004

Investigation Into The Use Of Bait Stations For The Control Of The European Wild Rabbit (Oryctolagus Cuniculus) In The Urban Bushland Reserve Of Bold Park, Perth, Western Australia, Malin Kordes

Theses : Honours

European rabbits in Australia have a significant impact on the environment and the economy. It is therefore necessary to implement control programs. In rural areas a number of methods including warren ripping and poisoning are frequently used. In urban areas though, rabbit control is not as easily accomplished because the use of many control methods is not appropriate. For example, the poison 1080 often cannot be used due to public health concerns and warren ripping cannot be used in conservation areas. Poisoning with pindone, an anticoagulant, is therefore one of few options available to the managers of urban reserves. However, …


Western Kingbird (Tyrannus Verticalis): Recently Established Breeding Bird In Arkansas, Elizabeth Ellis, Ragupathy Kannan Jan 2004

Western Kingbird (Tyrannus Verticalis): Recently Established Breeding Bird In Arkansas, Elizabeth Ellis, Ragupathy Kannan

Journal of the Arkansas Academy of Science

The Western Kingbird (Tyrannus verticalis) has nested for six consecutive years in Arkansas since 1998. Eleven nests of this species were observed in the summer of 2003 in urban areas of Fort Smith (Sebastian Co.) and Van Buren (Crawford Co.). All nests were on human-made structures. Of the 11, seven (64%) were located on power stations and the remaining four (36%) were on light posts. Mean nest height was 7.92 m (n = 11nests) and the mean width of nest poles was 31.18 cm (n= 4). Nest building lasted 12 to 13 days (mean = 12.5 days, n = 2 …

Characterization Of Association Patterns Of Coastal Migratory Bottlenose Dolphins, Tursiops Truncatus, In The Nearshore Waters Of Virginia Beach, Virginia, Holly Fearnbach

Biological Sciences Theses & Dissertations

Bottlenose dolphins, Tursiops truncatus, commonly occur in fission-fusion social systems. For this study, I analyzed photo-identification data from 1994 to 1999 to describe association patterns of bottlenose dolphins in the nearshore waters of Virginia Beach, Virginia. Bottlenose dolphins are present seasonally (late April until early November) in these waters and individuals are considered to be members of the North Atlantic coastal migratory stock. I selected 78 individuals for detailed analyses from the 972 dolphins identified in the study area. Those chosen as “select” dolphins had been sighted at least five times in three of the six study years; all …


Effect Of Pig Weaning Age And Commingling After The Nursery Phase On Humoral And Behavioral Indicators Of Well-Being And On Growth Performance, Sarah C. Arthur, Mari E. Davis, Jason K. Apple, Charles V. Maxwell Jan 2004

Effect Of Pig Weaning Age And Commingling After The Nursery Phase On Humoral And Behavioral Indicators Of Well-Being And On Growth Performance, Sarah C. Arthur, Mari E. Davis, Jason K. Apple, Charles V. Maxwell

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Two hundred and sixteen pigs were weaned at 14 or 21 d of age to determine the effect of weaning age and commingling after the nursery phase on growth and behavior of pigs in a wean-to-finish facility. Pigs were divided into older and younger age groups and allotted 12 pigs/pen with nine replications of each group. At the end of the nursery phase (d 34 after weaning), one-half of the pigs in each group were removed and commingled for the grower/finisher phase and the other half remained in their original pens. Beginning at weaning (d 0), pigs were monitored via …
