Consequences Of Hatch Phenology On Stages Of Fish Recruitment, David M. Bogner, Mark A. Kaemingk, Melissa R. Wuellner Jan 2016

Consequences Of Hatch Phenology On Stages Of Fish Recruitment, David M. Bogner, Mark A. Kaemingk, Melissa R. Wuellner

School of Natural Resources: Faculty Publications

Little is known about how hatch phenology (e.g., the start, peak, and duration of hatching) could influence subsequent recruitment of freshwater fishes into a population. We used two commonly sympatric fish species that exhibit different hatching phenologies to examine recruitment across multiple life stages. Nine yellow perch (Perca flavescens) and bluegill (Lepomis macrochirus) annual cohorts were sampled from 2004 through 2013 across larval, age-0, age-1, and age-2 life stages in a Nebraska (U.S.A.) Sandhill lake. Yellow perch hatched earlier in the season and displayed a more truncated hatch duration compared to bluegill. The timing of hatch …

Estimating Carbon Storage In Windbreak Trees On U.S. Agricultural Lands, W. B. Possu, James R. Brandle, G. M. Domke, M. Schoeneberger, Erin E. Blankenship Jan 2016

Estimating Carbon Storage In Windbreak Trees On U.S. Agricultural Lands, W. B. Possu, James R. Brandle, G. M. Domke, M. Schoeneberger, Erin E. Blankenship

School of Natural Resources: Faculty Publications

Assessing carbon (C) capture and storage potential by the agroforestry practice of windbreaks has been limited. This is due, in part, to a lack of suitable data and associated models for estimating tree biomass and C for species growing under more opengrown conditions such as windbreaks in the Central Plains region of the United States (U.S.). We evaluated 15 allometric models using destructively sampled Pinus ponderosa (Lawson & C. Lawson) data from field windbreaks in Nebraska and Montana. Several goodness-of-fit metrics were used to select the optimal model. The Jenkins’ et al. model was then used to estimate biomass for …

Foraging Decisions Underlying Restricted Space Use: Effects Of Fire And Forage Maturation On Large Herbivore Nutrient Uptake, Edward J. Raynor, Anthony Joern, Jesse B. Nippert, John M. Briggs Jan 2016

Foraging Decisions Underlying Restricted Space Use: Effects Of Fire And Forage Maturation On Large Herbivore Nutrient Uptake, Edward J. Raynor, Anthony Joern, Jesse B. Nippert, John M. Briggs

School of Natural Resources: Faculty Publications

Recent models suggest that herbivores optimize nutrient intake by selecting patches of low to intermediate vegetation biomass. We assessed the application of this hypothesis to plains bison (Bison bison) in an experimental grassland managed with fire by estimating daily rates of nutrient intake in relation to grass biomass and by measuring patch selection in experimental watersheds in which grass biomass was manipulated by prescribed burning. Digestible crude protein content of grass declined linearly with increasing biomass, and the mean digestible protein content relative to grass biomass was greater in burned watersheds than watersheds not burned that spring (intercept; F1,251 …

A Remotely Sensed Pigment Index Reveals Photosynthetic Phenology In Evergreen Conifers, John A. Gamon, K. Fred Huemmrich, Christopher Y.S. Wong, Ingo Ensminger, Steven Garrity, David Y. Hollinger, Asko Noormets, Josep Peñuelas

School of Natural Resources: Faculty Publications

In evergreen conifers, where the foliage amount changes little with season, accurate detection of the underlying “photosynthetic phenology” from satellite remote sensing has been difficult, presenting challenges for global models of ecosystem carbon uptake. Here, we report a close correspondence between seasonally changing foliar pigment levels, expressed as chlorophyll/carotenoid ratios, and evergreen photosynthetic activity, leading to a “chlorophyll/carotenoid index” (CCI) that tracks evergreen photosynthesis at multiple spatial scales. When calculated from NASA’s Moderate Resolution Imaging Spectroradiometer satellite sensor, the CCI closely follows the seasonal patterns of daily gross primary productivity of evergreen conifer stands measured by eddy covariance. This discovery …

Mesoscale Climatology And Variation Of Surface Winds Over The Chukchi–Beaufort Coastal Areas, Jing Zhang, Fuhong Liu, Wei Tao, Jeremy Krieger, Martha Shulski, Xiangdong Zhang

School of Natural Resources: Faculty Publications

The detailed mesoscale climatology of surface winds in the Chukchi–Beaufort Seas and adjacent Arctic Slope region is analyzed using the recently developed Chukchi–Beaufort High-Resolution Atmospheric Reanalysis (CBHAR). Within the study area, surface winds are mainly driven by the prevailing synoptic weather patterns of the Beaufort high and Aleutian low and are further modulated by local geographic features through thermodynamic and dynamic processes. Sea breezes, up- or downslope winds, and the mountain barrier jets are all clearly captured by CBHAR. Sea breezes emerge in June–September and last most of the day, with a maximum spatial extent 100km inland and 50 km …

Winter Diet And Hunting Success Of Canada Lynx In Colorado, Jacob S. Ivan, Tanya M. Shenk Jan 2016

Winter Diet And Hunting Success Of Canada Lynx In Colorado, Jacob S. Ivan, Tanya M. Shenk

School of Natural Resources: Faculty Publications

Information regarding the diet of Canada lynx (Lynx canadensis) at the southernmost extent of its range is critical for managing the species under current and predicted climate conditions. Therefore, from 1999–2009, we investigated winter diet and hunting strategies of Canada lynx in Colorado, USA by tracking individuals in the snow to identify sites where lynx encountered and killed prey. Similar to other parts of lynx range, snowshoe hares (Lepus americanus) were the primary winter food in Colorado, especially when considering total biomass consumed. Red squirrels (Tamiasciurus hudsonicus) comprised the bulk of the remaining food …

The Sensitivity Of Carbon Exchanges In Great Plains Grasslands To Precipitation Variability, M. D. Petrie, N. A. Brunsell, R. Vargas, S. L. Collins, L. B. Flanagan, N. P. Hanan, M. E. Litvak, Andrew E. Suyker Jan 2016

The Sensitivity Of Carbon Exchanges In Great Plains Grasslands To Precipitation Variability, M. D. Petrie, N. A. Brunsell, R. Vargas, S. L. Collins, L. B. Flanagan, N. P. Hanan, M. E. Litvak, Andrew E. Suyker

School of Natural Resources: Faculty Publications

In the Great Plains, grassland carbon dynamics differ across broad gradients of precipitation and temperature, yet finer-scale variation in these variables may also affect grassland processes. Despite the importance of grasslands, there is little information on how fine-scale relationships compare between them regionally. We compared grassland C exchanges, energy partitioning and precipitation variability in eight sites in the eastern and western Great Plains using eddy covariance and meteorological data. During our study, both eastern and western grasslands varied between an average net carbon sink and a net source. Eastern grasslands had a moderate vapor pressure deficit (VPD = 0.95 kPa) …

Status Of Knowledge Of The Shovelnose Sturgeon (Scaphirhynchus Platorynchus, Rafinesque, 1820), Q. E. Phelps, S. J. Tripp, M. J. Hamel, J. Koch, E. J. Heist, J. E. Garvey, K. M. Kappenman, M. A. H. Webb

School of Natural Resources: Faculty Publications

The range of Shovelnose Sturgeon (SVS) Scaphirhynchus platorynchus in the great rivers of central North America has contracted, but most remaining populations are considered stable, likely due to a combination of successful harvest regulations and longitudinal continuity of many river reaches, despite damming in upper reaches. The evolutionary relationships of SVS relative to sister taxa is still a matter of debate. Genetic diversity varies across the range, with substantial haplotype overlap among SVS and its congeners. Shovelnose Sturgeon mature early at 5–7 years, and spawn every 2– 3 years. Some individuals may spawn in fall. Whether this species migrates is …

Spatiotemporal Patterns Of Water Table Fluctuations And Evapotranspiration Induced By Riparian Vegetation In A Semiarid Area, Weifeng Yue, Tiejun Wang, Trenton E. Franz, Xunhong Chen Jan 2016

Spatiotemporal Patterns Of Water Table Fluctuations And Evapotranspiration Induced By Riparian Vegetation In A Semiarid Area, Weifeng Yue, Tiejun Wang, Trenton E. Franz, Xunhong Chen

School of Natural Resources: Faculty Publications

Groundwater evapotranspiration (ETg) links various ecohydrological processes and is an important component in regional water budgets. In this study, an extensive monitoring network was established in a semiarid riparian area to investigate various controls on the spatiotemporal pattern of water table fluctuations (WTFs) and ETg induced by riparian vegetation. Along a vegetation gradient (~1200 m), diurnal WTFs were observed during a growing season in areas covered by woody species (Populus sect. Aigeiros and Juniperus virginiana) and wet slough vegetation (Panicum virgatum and Bromus inermis) with deeper root systems; whereas, no diurnal WTFs were …

The Framework For 21st Century Learning: A First-Rate Foundation For Music Education Assessment And Teacher Evaluation, Ashley Danielle Gilbert Jan 2016

The Framework For 21st Century Learning: A First-Rate Foundation For Music Education Assessment And Teacher Evaluation, Ashley Danielle Gilbert

Glenn Korff School of Music: Faculty Publications

Federal laws and funding initiatives, such as the No Child Left Behind Act and the Race to the Top campaign, have created an increasing incentive for schools nationwide to document student progress, standardize assessment practices, and evaluate teachers according to student success. In response, the Common Core State Standards, a popular yet controversial policy, has emerged. Implemented at the state level, these standards focus heavily on the areas of English language arts and mathematics, subjects not traditionally incorporated to a great extent in music classrooms. In order for music to maintain a role as an essential subject in the school …

The highly stable spin of neutron stars can be exploited for a variety of (astro)physical investigations. In particular, arrays of pulsars with rotational periods of the order of milliseconds can be used to detect correlated signals such as those caused by gravitational waves. Three such 'pulsar timing arrays' (PTAs) have been set up around the world over the past decades and collectively form the 'International' PTA (IPTA). In this paper, we describe the first joint analysis of the data from the three regional PTAs, i.e. of the first IPTA data set. We describe the available PTA data, the approach presently …

Oh What A Tangled Web We Weave: Mind Mapping As Creative Spark To Optimize Transactional Clinic Assignments, Brett C. Stohs Jan 2016

Oh What A Tangled Web We Weave: Mind Mapping As Creative Spark To Optimize Transactional Clinic Assignments, Brett C. Stohs

Nebraska College of Law: Faculty Publications

Client assignments are among the most important factors that affect a student's experience in a live-client transactional law clinic. Student "attorneys" are presented with meaningful opportunities to engage with and learn from clients by applying their still-developing professional bona fides to real people with legal challenges. As a result, decisions regarding allocation and distribution of client matters are among the most important pedagogical decisions transactional clinical faculty make. By taking into account the unique and sometimes complex individual characteristics of each client and student, clinical faculty can optimize these allocations and maximize achievement of important objectives. Mind mapping can help …

Investigating Declining Enrolments In Secondary Mathematics, G Hine Jan 2016

Investigating Declining Enrolments In Secondary Mathematics, G Hine

Education Conference Papers

This research paper examines the perspective of the Heads of Learning Area: Mathematics (HOLAMs) within all Western Australian secondary schools as to why they felt capable students were not enrolling in the two higher-level mathematics courses of study. All HOLAMs were invited to participate in a single, anonymous online survey comprising predominantly qualitative items. Key findings indicate perceptions of student awareness that two mathematics courses are not needed for university entrance, there are other viable and less rigorous courses of study available, and students can maximise their Australian Tertiary Admissions Ranking (ATAR) score without completing these mathematics courses.

Captain Zero . . . Hero Or Villain?, C Hurst, D Hurrell

Education Conference Papers

Our current research into children's multiplicative thinking has shown that children have the capacity to think multiplicatively and that some aspects of multiplicative thinking are more thoroughly understood than others. We look at a data set obtained over three classes in the same year level and explore the considerable variation in responses to several key questions on a multiplicative thinking quiz. The questions relate to the 'times bigger' notion in comparing numbers, the ability to use standard place value partitioning when operating, the ability to articulate what happens when numbers are multiplied and divided by powers of ten, and the …

Does Cognition Matter? Current Pedagogical Practice And The Need For Reform, Clara Coleman, Shannon Kennedy-Clark, Thuan Thai Jan 2016

Does Cognition Matter? Current Pedagogical Practice And The Need For Reform, Clara Coleman, Shannon Kennedy-Clark, Thuan Thai

Education Conference Papers

Recent debate in the educational sphere highlights the continuing dilemma that is the creation and implementation of a true 21st century classroom in secondary schools across Australia. A difficulty with these ongoing attempts to reform teaching and learning is the behaviourist educational paradigm through which Western schools operate. This traditional perspective influences the ways in which modern researchers, policy-makers, teachers and the wider community all conceptualise education and its purpose. As such, this paper aims to establish that this understanding of education needs to be overthrown, in light of a changing global context and the evolving needs of students. …
