Non-Nutritive Suck Parameter In Preterm Infants With Rds, Meredith Estep, Steven M. Barlow, Rajesh Vantipalli, Donald Finan, Jaehoon Lee

Department of Special Education and Communication Disorders: Faculty Publications

Objective—To characterize the integrity of non-nutritive suck (NNS) parameters among three groups of preterm infants ranging from normal to those with progressive degrees of respiratory distress syndrome (RDS).

Study Design—NNS compression waveforms were sampled from 55 infants in the neonatal intensive care unit using a silicone pacifier electronically instrumented for intraluminal pressure. Seven select NNS parameters were measured at two different sessions, and statistically analyzed using a General Linear Model Analysis of Covariance.

Results and Conclusions—Preterm infants with a more extensive history of RDS and oxygen therapy manifest significantly (p≤0.001) degraded performance on six of the seven NNS measures. This …

Development And Evaluation Of A Bioenergetics Model For The Inland Silverside In Freshwater Systems, Christopher J. Chizinski, Caleb G. Huber, Kevin L. Pope

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Consumption and respiration parameters were fit for inclusion in a bioenergetics model developed to predict the growth of the inland silverside Menidia beryllina. Although this model accurately predicted inland silverside growth through the initiation of spawning, it failed to predict the growth of reproductively active inland silversides. Model simulations provided initial evidence that a single model cannot predict the lifetime growth patterns of this species. Instead, a two-stage model is probably necessary to account for the physiological differences between the prespawning and active-spawning stages. In addition, the bioenergetics models of short-lived (life span,< 2 years) fishes may need to include a better means for assessing the direct energy expenditure for reproduction.

Power Laws, Discontinuities And Regional City Size Distributions, Ahjond S. Garmestani, Craig R. Allen, Colin M. Gallagher

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Urban systems are manifestations of human adaptation to the natural environment. City size distributions are the expression of hierarchical processes acting upon urban systems. In this paper, we test the entire city size distributions for the southeastern and southwestern United States (1990), as well as the size classes in these regions for power law behavior. We interpret the differences in the size of the regional city size distributions as the manifestation of variable growth dynamics dependent upon city size. Size classes in the city size distributions are snapshots of stable states within urban systems in flux.

Management Plan 2008-2012

National Invasive Species Council

The 2008–2012 National Invasive Species Management Plan (2008 Plan) is the first revision of the 2001 Plan, as mandated by EO 13112. This document will direct Federal efforts (including overall strategy and objectives) to prevent, control and minimize invasive species and their impacts within the next five fiscal years (2008 through 2012). If necessary, it may be updated more frequently to reflect changes in circumstances, agency plans and priorities. NISC member agencies, ISAC members, NISC staff, stakeholders and other experts have provided input in drafting this revision, which replaces the 2001 Plan.

The 2008 Plan is focused upon five “Strategic …

Remarks Of The Director, U.S. National Park Service, At The Plenary Session On North American Park Directors And Global Change, Mary A. Bomar

United States National Park Service: Publications

Thank you, Ernie [Ortega] for your kind introduction. I am honored to be here this evening and to share the microphone with my colleagues, Ernesto Enkerlin and Alan Latourelle. Global change is expansive, inescapable, and all encompassing—and central to the challenges and opportunities the three of us share with everyone in this room. It is our shared privilege to have this chance to address the George Wright Society, which collectively represents the thoughtful analysis of what we manage and where we are headed. Management of protected areas is impossible unless we recognize the need for anticipation of and reaction to …

Effective Resource Advising And Suppression Rehabilitation, Baer Teams, Planning, And Assessments, Sandee Dingman

United States National Park Service: Publications

During fire management activities, whether that management is suppression or wildland fire use (where natural ignitions are allowed to burn under specific conditions for resource benefit), it is essential that resource concerns are communicated to the incident commander. The most common approach is to assign one or more people from the resource management staff to the incident, in the role of resource advisor(s). The resource advisor provides daily input to the incident commander or his/her designee, often the plans chief, in the development of fire suppression strategies and tactics to minimize or mitigate the expected impacts of fire and fire …

Paleontological Parks And Global Change, Regan Dunn, Theodore Fremd, Matthew Smith

United States National Park Service: Publications

Paleontology, the study of organisms and processes preserved in a geologic context, can be practiced in over 180 units of the national park system. Much more than just the collecting of different kinds of fossils to be stored in a museum, the study of the fossil record is the only means by which we can understand past climatic changes and the effects of such changes on biotas (changes such as extinction, speciation, immigration, and evolutionary events). In combination with the fossil record, comprehensive studies of geological, sedimentological, and geochemical records can inform us about other aspects of major climatic perturbations …

The Science Of Large Dam Removal: Removing Dams On The Elwha River, Olympic National Park, Jerry Freilich

United States National Park Service: Publications

This paper centers on the development of a research consortium to study ecological effects of dam removal. Long-time public interest has centered on the National Park Service’s plan to remove two hydropower dams from the Elwha River in Olympic National Park. The Elwha is not only the largest dam removal ever attempted but is also unique in that land above the dams is within Olympic National Park, removing the confounding anthropogenic factors in other dam removals nationwide. I will provide a general update on the project to set the scene for the science part, which is actually the story I …

When It’S Better Not To Manage Nps Resources, Jerry Freilich, Phillip Cafaro

United States National Park Service: Publications

We believe that this means preserving the full complement of native flora and fauna, and allowing these species to live their lives without interference from humans. It also means preserving unruly, unpredictable processes such as fires, floods, and insect outbreaks that have shaped park landscapes and, over the eons, helped create wild species themselves.

Since its inception, the “leave nature alone” philosophy has had strong advocates within the Park Service and among its friends. In the 1920s, for example, George Wright (NPS scientist), Joseph Grinnell (Zoology professor at the University of California–Berkeley), and Charles C. Adams (at the College of …

Great Lakes Research And Education Center, Indiana Dunes National Lakeshore: Connecting Research, Education, And Outreach Through Research Internships, Joy Marburger

United States National Park Service: Publications

The National Park Service (NPS) initiated the Natural Resources Challenge in 1999. The Challenge resulted in the development of research learning centers (RLCs) throughout the country. The RLCs increase the effectiveness and communication of scientific research in national parks by (1) facilitating use of parks for scientific inquiry; (2) supporting sciencebased decision-making; (3) communicating current research information; and (4) promoting resource stewardship through partnerships. RLCs initiate, support, and implement a wide variety of research projects and provide opportunities for university students to work with researchers and park managers. The Great Lakes Research and Education Center initiated a university student research …

Historic Resource Study: Agate Fossil Beds National Monument, Gail Evans-Hatch

United States National Park Service: Publications

As steward of many of the United States' most important cultural and natural resources, the National Park Service (NPS) is required to create background documents along with specific plans aimed at managing and protecting these resources for the enjoyment of present and future generations. An important aspect of managing cultural landscapes requires knowing the past of those landscapes. A historic resource study (HRS) project involves researching and presenting the history of a park. A HRS also attempts to identify and evaluate the importance of all cultural resources within that park. Researching and presenting the broader historical context of a park …

The Role Of Protected Areas As Bird Stop-Over Habitat: Ecology And Habitat Utilization By Migrating Land Birds Within Colorado River Riparian Forests Of Southwestern North America, Charles Van Riper Iii, Kristina L. Paxton, Carena J. Van Riper, Kimberly A. Van Riper, Laura Mcgrath, J. J. Fontaine

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

In southwestern North America, riparian habitats have declined precipitously in the last century both within and outside protected areas such as national parks,U.S. Fish and Wildlife Service refuges, and Bureau of Land Management and biosphere reserve lands. These declines are primarily due to anthropogenic perturbations such as alterations in river flow regimes, agricultural conversion, livestock grazing, and urban expansion (Webb et al. 2003). In the southwestern United States and northwestern Mexico the decline of riparian habitat and loss of native cottonwood (Populus fremontii), willow (Salix gooddingii) gallery forests, and adjacent mesquite (Prosopis sp.) bosques has …

A Simple Model For Predicting Survival Of Angler-Caught And Released Largemouth Bass, Gene R. Wilde, Kevin L. Pope

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

We conducted a controlled experiment in the laboratory to assess the influence of anatomical hooking location and water temperature on survival of angler-caught and released largemouth bass Micropterus salmoides. Survival was 98% (58 of 59 fish) among fish that were hand-hooked within the oral cavity (including the gills), whereas survival was 66% (33 of 50 fish) among fish that were hand-hooked in the esophagus. Survival of hooked fish was not significantly influenced by water temperature (7–27 °C) or the hooking location × water temperature interaction. We combined our results with prior research to develop a predictive model of largemouth bass …

Temporal Distribution Of Harvested Mid-Continent Sandhill Cranes Within The Central Flyway States During The 1997–2001 Hunting Seasons, Adrianna C. Araya, James A. Dubovsky

Proceedings of the North American Crane Workshop

Since 1975, annual harvest estimates for Mid-Continent sandhill cranes (Grus canadensis) have been collected in all states for which a hunting season has been authorized by the U.S. Fish and Wildlife Service (Service). Although these data have been used to monitor the harvest of the Mid-Continent population, analyses to promote understanding of the temporal distribution of harvested sandhill cranes by individual states throughout the Central Flyway have not been conducted. For the 1997-2001 hunting seasons, we collected harvest questionnaires from 4,408 hunters in the Central Flyway who provided information about the date, location, and number of harvested sandhill …

Is Magnitude Of Fat Storage By Spring-Staging Sandhill Cranes Declining In The Central Platte River Valley, Nebraska?, David A. Brandt, Gary L. Krapu

Proceedings of the North American Crane Workshop

Proximate analyses of carcasses of sandhill cranes (Grus canadensis) collected in the Central Platte River Valley (CPRV), Nebraska, during spring 1999 indicated a marked decline in fat levels from springs 1978 and 1979. Concern that amounts of fat cranes stored by their spring departures from the CPRV may have further declined prompted this evaluation. For our assessment, we made use of morphological measurements (culmen post nares, tarsus, flattened wing chord) along with body mass on each of 810 sandhill cranes that were collected for proximate analysis or captured with rocket nets at widely distributed sites in the CPRV during 1978-1979 …

Hunting Success For Mid-Continent Sandhill Cranes In The Central Flyway: Comparing Current And Historic Results, James A. Dubovsky, Adrianna C. Araya

Proceedings of the North American Crane Workshop

Sport hunting for the Mid-continent population of sandhill cranes (Grus canadensis) in the United States resumed in New Mexico in 1961 after a 45-year moratorium. Interest in crane hunting continued to increase and by 1975, 8 states were participating in sandhill crane hunting. Currently, hunting seasons have been established in all Central Flyway states except Nebraska. Efforts to collect information on the annual harvest of sandhill cranes began in 1975 when hunters were required to obtain federal sandhill crane hunting permits. The permits included a hunting diary whereby hunters were asked to record information about their daily hunting …

Feather Molt Of Nonmigratory Whooping Cranes In Florida, Martin J. Folk, Stephen A. Nesbitt, Jeannette M. Parker, Marilyn G. Spalding, Stephen B. Baynes, Kristen L. Candelora

Proceedings of the North American Crane Workshop

Molt patterns of wild whooping cranes (Grus americana) are largely unknown, and what knowledge we have has been based on scant data. We documented patterns of feather molt in nonmigratory whooping cranes in Florida during 1993-2005. All birds replaced flight feathers (remiges) in a synchronous (simultaneous) manner and spent time flightless. It took 38-46 days (mean = 44 days, n = 8) for feathers to regrow and birds to regain flight ability. When flightless due to remigial molt, cranes became more secretive and spent more time in wetlands during feather regrowth. Most (70%) whooping cranes first molted their …

Factors Influencing Greater Sandhill Crane Nest Success At Malheur National Wildlife Refuge, Oregon, Gary L. Ivey, Bruce D. Dugger

Proceedings of the North American Crane Workshop

We used logistic regression to model the effects of weather, habitat, and management variables on Greater Sandhill Crane (Grus canadensis tabida) nest success at Malheur National Wildlife Refuge in southeast Oregon. We monitored 506 nests over 9 breeding seasons. Mean apparent nest success was 72% ± 4% and varied from 51 to 87%. Nest success was lower one year after a field was burned and declined with nest initiation date. Nest success was higher during warmer springs, in deeper water, and in years with moderate precipitation. Haying, livestock grazing, and predator control did not influence nest success. We …

Sandhill Crane Wintering Ecology In The Sacramento–San Joaquin Delta, California, Gary L. Ivey, Caroline P. Herziger

Proceedings of the North American Crane Workshop

We studied wintering sandhill crane (Grus canadensis) ecology in 2002–2003 in the Sacramento-San Joaquin Delta of California, focusing on Staten Island, a corporate farm which was acquired by The Nature Conservancy and managed to promote sustainable agriculture that is beneficial to wildlife. Our purpose was to define habitat conservation needs for cranes, including the state-threatened greater subspecies (G. c. tabida). Research was conducted through intensive surveys by vehicle of crane foraging and roosting behavior. We estimated that about 1,500 greaters used Staten Island, which is a significant portion of the Central Valley Population of greater sandhill …

Risk Factors Associated With Developmental Limb Abnormalities In Captive Whooping Cranes, Cristin Kelley, Barry K. Hartup

Proceedings of the North American Crane Workshop

This retrospective survey identifies potential risk factors for developmental limb abnormalities in whooping crane (Grus americana) chicks reared at the International Crane Foundation between 1990 and 2006. We summarized a series of biologicallyrelevant pre- and post-hatch variables from this population using in-house aviculture and veterinary records, and then compared them between chicks with and without developmental carpal, toe and leg deformities. Chi-square analysis revealed associations between 1) rearing style and each type of deformity, 2) egg source and carpal and toe deformities, and 3) the pre-existence of a toe deformity and carpal and leg deformities. Multivariate analyses using …

Habitat Characteristics Influencing Sandhill Crane Nest Site Selection, Anne E. Lacy, Su Liying

Proceedings of the North American Crane Workshop

The breeding population of greater Sandhill cranes (Grus canadensis tabida) in Wisconsin has greatly increased since the population was nearly extirpated in the mid-1930’s (Henika 1936). The International Crane Foundation (ICF) has been studying these birds for over 10 years in an area with one of the highest density of breeding cranes in the Midwest; we have calculated a nesting density of over 5 pairs/km2 (ICF unpublished data). Prior to this study, little was known about the habitat characteristics that may be influencing nest site selection. We conducted nest surveys by helicopter during the last week of April …

Selection Criteria For Important Sites For Wintering Sandhill Cranes In The Mexican Altiplano, Alberto Lafon Terrazas, Eduardo Carrera Gonzalez

Proceedings of the North American Crane Workshop

Conservation of natural resources has increased worldwide, and Mexico shows the same tendency. Unfortunately, selection criteria for conservation areas and objectives do not always follow a methodology that will allow for optimum selection. In Mexico and other countries we have a series of priority sites proposed by experts in various biodiversity areas, based on knowledge of the existing biological resources of the site. This results in two situations: more attention and resources are given to certain areas, but no resources are invested in sites that could be of equal or greater importance than those currently proposed. This leads to knowledge …

Sandhill Crane Nest Habitat Selection And Factors Affecting Nest Success In Northwestern Minnesota, Stephen J. Maxson, John R. Fieberg, Michael R. Riggs

Proceedings of the North American Crane Workshop

We studied 62 greater sandhill crane (Grus canadensis tabida) nests in northwestern Minnesota during 1989-1991 to document nest habitat use and selection, nest success, and factors associated with nest success. We recorded 15 habitat variables at each nest and at a randomly selected site in the same wetland. Nests were in basins 0.01-601 ha (Median = 2.2 ha) and at water depths 0-35.7 cm (Median = 9.7 cm). Cattail (Typha sp.) was the dominant vegetation at 58.0% of nests while 21.0% were at sites dominated by phragmites (Phragmites australis). Conditional logistic regression models indicated …
