Testing Northern Bobwhite Reintroduction Techniques In The Northern Edge Of Their Range, William Macaluso, Christopher K. Williams, Theron M. Terhune Ii Nov 2017

Testing Northern Bobwhite Reintroduction Techniques In The Northern Edge Of Their Range, William Macaluso, Christopher K. Williams, Theron M. Terhune Ii

National Quail Symposium Proceedings

Pen-rearing young frequently fails as a reintroduction technique in game birds because of low postrelease survival rates in the wild. This may be caused by a combination of poor genetics from domestication, unhealthy birds, birds that do not exhibit wild behavior, or birds that are unfamiliar with their surroundings after hard releases. Recent research suggests that parent-rearing, involving pre- and posthatch imprinting of wild-strain northern bobwhite (Colinus virginianus) chicks by adults, may be a viable option for restoring populations. Imprinting potentially causes reintroduced birds to exhibit more natural behavior. We tested this method against a slightly modified traditional …

The Effect Of Age-At-Release On Survival Of Adoptive Parent-Reared Bobwhite Chicks, Kyle D. Lunsford, Theron M. Terhune Ii, James A. Martin Nov 2017

The Effect Of Age-At-Release On Survival Of Adoptive Parent-Reared Bobwhite Chicks, Kyle D. Lunsford, Theron M. Terhune Ii, James A. Martin

National Quail Symposium Proceedings

Translocation of wild northern bobwhites (Colinus virginianus) to restore local populations is a viable conservation tool under some scenarios; however, the supply of wild bobwhites is limited. Bobwhites can be artificially propagated, as an alternative to translocation, using methods that mimic natural brood-rearing. The parent-rearing adoptive process (PRAP) uses wild-strain bobwhite adults to brood and foster newly hatched wild-strain chicks in outdoor aviaries that emulate a natural environment. Adoptive parent-reared bobwhites have higher survival rates than artificially-reared bobwhites but only a single age-of-release (i.e., 6-weeks) has been tested. We tested the effect of age-at-release (3, 6, and 9-weeks) …

Contributions Of Translocation To Northern Bobwhite Population Recovery, D. Clay Sisson, Theron M. Terhune Ii, William E. Palmer, Reggie Thackston Nov 2017

Contributions Of Translocation To Northern Bobwhite Population Recovery, D. Clay Sisson, Theron M. Terhune Ii, William E. Palmer, Reggie Thackston

National Quail Symposium Proceedings

The National Bobwhite Conservation Initiative (NBCI 2.0) is a range-wide plan for recovering northern bobwhites (Colinus virginianus; hereafter, bobwhite[s]). Using geospatial analysis informed by expertise from practitioners, the plan categorizes landscapes into restoration potential by weighing biological constraints and opportunities such that targeted habitat management will produce bobwhite population growth. A fundamental assumption of the NBCI 2.0 for achieving recovery goals is that bobwhite source populations currently exist on the landscape at densities necessary to (re)colonize newly established or improved habitat. However, we have found that these source populations can be very low or non-existent, especially in northern …

Response Of Grassland Birds To Agricultural Intensity At Different Spatial Scales In Texas, Anna Matthews, M. Clay Green, James Giocomo Nov 2017

Response Of Grassland Birds To Agricultural Intensity At Different Spatial Scales In Texas, Anna Matthews, M. Clay Green, James Giocomo

National Quail Symposium Proceedings

The decline in grassland birds is often associated with habitat loss due to intensity of conversion to agricultural lands and the alterations of natural disturbances. We sought to identify agricultural effects at differing scales that correlate to Texas grassland bird abundance, especially northern bobwhite (Colinus virginianus). Ninety-five roadside routes were surveyed in 20 Texas counties ranging from the Oklahoma border to the coastal plains. We conducted point counts in May and June from 2013 to 2016. To estimate the coarse effects of agriculture on bird abundance at a county level, we used number of cattle and area of …

Perotto-Baldivieso, Fidel Hernández, Eric D. Grahmann, Atiye Z. Okay, X. Ben Wu, Markus J. Peterson, Heather Hannusch, Jose Mata, Jaclyn Robles

National Quail Symposium Proceedings

The northern bobwhite (Colinus virginianus) has experienced range wide declines over the last several decades, primarily due to loss and fragmentation of habitat. As populations decline, there is a need for understanding factors that impact bobwhite population persistence at local and regional spatial scales. Our goal was to assess changes in land use and their relationship to bobwhite declines at 3 different spatial scales (region, county, and home range) in Texas, Oklahoma, and Louisiana. We used North American Breeding Bird Survey (BBS) data from 1974-2014 to create abundance maps and trends. At the regional scale, we compared bobwhite …

The Law Of Interspersion And The Principle Of Edge: Old Arguments And A New Synthesis, Mark M. Mcconnell, L. Wes Burger Jr., James A. Martin Nov 2017

The Law Of Interspersion And The Principle Of Edge: Old Arguments And A New Synthesis, Mark M. Mcconnell, L. Wes Burger Jr., James A. Martin

National Quail Symposium Proceedings

Leopold’s interspersion hypothesis has experienced fluctuating acceptance, opposition and neglect due to its unintentional ambiguous description and seemingly simplistically universal application. Originally developed to describe the positive association between animal density and habitat heterogeneity in the landscape, the hypothesis has been mischaracterized as the principle of edge resulting from Guthery and Bingham’s (1992) assertion that the interspersion hypothesis could be modeled by the amount of ‘high contrast’ edge and that edge density and interspersion were synonymous. We contend that Leopold’s original intention was not to promote more edge density is always better but rather to promote interspersion of habitat types …

An Evaluation Of Northern Bobwhite Conservation Research: A Call For Large-Scale Studies, Lex J. Gomez, Kelly S. Reyna Nov 2017

An Evaluation Of Northern Bobwhite Conservation Research: A Call For Large-Scale Studies, Lex J. Gomez, Kelly S. Reyna

National Quail Symposium Proceedings

Northern bobwhite (Colinus virginianus) populations have declined throughout the species’ range since the 1960s. Habitat loss and degradation are thought to have largely contributed to this decline by reducing the amount of space and resources required to sustain viable quail populations. Previous studies have attempted to address this issue by focusing on ranch-level management of bobwhites instead of on the effectiveness of large-scale techniques. Here, we review current and historical studies that have facilitated the implementation of management techniques on multiple scales. In doing so, we will also reveal the shortcomings of such studies by highlighting their narrowed …

The Role Of Joint Ventures In Northern Bobwhite Conservation, Stephen Demaso Nov 2017

The Role Of Joint Ventures In Northern Bobwhite Conservation, Stephen Demaso

National Quail Symposium Proceedings

Partnerships are crucial part of northern bobwhite (Colinus virginianus) conservation. A key principle is that no single entity can effectively address the complex landscape-level conservation issues to sustain populations and their supporting habitats in perpetuity. Joint Ventures (JVs) use a partnership based approach to deliver specific bird population and habitat objectives within their geography. Currently, 7 of the 12 JVs that occur in the North American bobwhite range have bobwhites listed as a priority species. This presentation will cover various topics including: 1) the history of JVs in North America; 2) an overview of the variety of models …

Predicting Northern Bobwhite Habitat In Semiarid Rangeland Using Landsat Imagery, Jeffrey G. Whitt, Kelly S. Reyna Nov 2017

Predicting Northern Bobwhite Habitat In Semiarid Rangeland Using Landsat Imagery, Jeffrey G. Whitt, Kelly S. Reyna

National Quail Symposium Proceedings

Multiple studies have attempted to model northern bobwhite (Colinus virginianus) distribution using classified remotely sensed imagery in combination with pattern recognition software. These models tend to be more accurate in humid subtropical regions. To identify bobwhite habitat in subhumid and semiarid rangeland, we performed our own classification on 4 LANDSAT scenes of Clay County, Texas, from July and December 2015. Stands of mature little bluestem (Schizachyrium scoparium) provide excellent bobwhite nesting cover and could be identified using LANDSAT imagery. Habitat was scored from 0 to 1.0 based on estimated range health, presence of little bluestem, and …

Vegetation And Arthropod Responses To Brush Reduction By Grubbing And Stacking, Carter Crouch, J. Alfonso Ortega-Santos, David B. Wester, Fidel Hernández, Leonard A. Brennan, Greta L. Schuster Nov 2017

Vegetation And Arthropod Responses To Brush Reduction By Grubbing And Stacking, Carter Crouch, J. Alfonso Ortega-Santos, David B. Wester, Fidel Hernández, Leonard A. Brennan, Greta L. Schuster

National Quail Symposium Proceedings

Grubbing is a mechanical brush-reduction technique that allows targeting of mesquite (Prosopis glandulosa) and huisache (Vachellia farnesiana) and can be used to open lanes for hunting northern bobwhites (Colinus virginianus). Follow-up treatments of stacking allow the piling up of downed brush. We initiated this study on the Santa Gertrudis Division of the King Ranch, Inc., Texas, to determine effects of grubbing and stacking on vegetation and arthropod communities important to bobwhite. We hypothesized that grubbing and stacking would be able to selectively remove mesquite and huisache while leaving mixed brush species largely intact. We …

Temperature Assessment On A Reclaimed Surface Mine During Northern Bobwhite Breeding Season: Considerations For Habitat Management, Donald M. Yow, Jeremy P. Orange, John J. Morgan, Gary Sprandel, Danna L. Baxley, Eric Williams Nov 2017

Temperature Assessment On A Reclaimed Surface Mine During Northern Bobwhite Breeding Season: Considerations For Habitat Management, Donald M. Yow, Jeremy P. Orange, John J. Morgan, Gary Sprandel, Danna L. Baxley, Eric Williams

National Quail Symposium Proceedings

Ground-level air temperatures were assessed within 4 distinct habitat areas on a managed reclaimed surface mine at Peabody Wildlife Management Area, Kentucky, 26 June–17 July 2015, during the northern bobwhite (Colinus virginianus) brood season. Habitat consisted of disked and nondisked areas of native grass and an invasive species, sericea lespedeza (Lespedeza cuneata). Disked areas offered more open space for bobwhite mobility and experienced higher average temperatures than nondisked sites. Although statistically significant, differences in air temperature between disked and nondisked areas were likely too small to have practical implications for bobwhite habitat management in Kentucky under …

Temporal And Spatial Assessment Of Usable Space And Cover Type Interspersion For Northern Bobwhites On Private Farmlands In Southwestern Ohio, Robert J. Gates, Mark J. Wiley, Adam K. Janke, Marjorie R. Liberati Nov 2017

Temporal And Spatial Assessment Of Usable Space And Cover Type Interspersion For Northern Bobwhites On Private Farmlands In Southwestern Ohio, Robert J. Gates, Mark J. Wiley, Adam K. Janke, Marjorie R. Liberati

National Quail Symposium Proceedings

Contemporary landscape change driven by socio-economic forces and advances in agricultural technology do not favor northern bobwhites (Colinus virginianus) in the Midwestern United States. The challenge of bobwhite conservation is to provide sufficient quantities of habitat with optimal configurations in proportions that satisfy needs throughout the year on private-owned working lands. We radio-tracked 58 coveys and 98 individual birds throughout the year in 2009-10 and 2010-11 on privately owned farmland in southwestern Ohio. We investigated temporal changes in usable space from use-availability data. Estimated proportions of usable space based on analyses of habitat selection across four study sites …

Strategic Habitat Conservation For Declining Grassland Wildlife Populations In The Oaks And Prairies Joint Venture, James Giocomo, Johnathan Hayes, Kenneth Gee, Jeff Raasch, Robert Perez Nov 2017

Strategic Habitat Conservation For Declining Grassland Wildlife Populations In The Oaks And Prairies Joint Venture, James Giocomo, Johnathan Hayes, Kenneth Gee, Jeff Raasch, Robert Perez

National Quail Symposium Proceedings

Degradation and conversion of functioning grassland ecosystems in North America has driven significant declines in grassland wildlife populations across multiple taxa. In an effort to address declines in the grasslands of Oklahoma and Texas, a number of governmental agencies and Non-Governmental Organizations have partnered to form the Oaks and Prairies Joint Venture (OPJV) to more strategically and collaboratively deliver conservation actions in this region. With northern bobwhite (Colinus virginianus) as the flagship species, OPJV has worked to implement a fully integrated Strategic Habitat Conservation framework that works at multiple scales to conduct biological planning, landscape conservation design, habitat …

Molecular Ecology Of New World Quails: Messages For Managers, Damon Williford, Randy W. Deyoung, Leonard A. Brennan Nov 2017

Molecular Ecology Of New World Quails: Messages For Managers, Damon Williford, Randy W. Deyoung, Leonard A. Brennan

National Quail Symposium Proceedings

Recent genetic studies of New World quails (Odontophoridae) have yielded important, and sometimes, counter-intuitive insights regarding their evolutionary relationships, genetic diversity, population structure, and biogeographic history. Many of these new insights have important implications for managers. New World quails are a distinct family within galliforms, most closely related to guineafowl (Numididae) and pheasants (Phasianidae) rather than guans and chachalacas (Cracidae). The African stone partridges (Ptilopachus spp.) are the closest living relatives of the New World quails. The combination of phylogeographic studies with ecological niche modeling has revealed the biogeographic history of several species of New World quails, including Pleistocene …

Response Of Northern Bobwhites To Habitat Improvement On Private Lands In The Rolling Plains Of Texas, C. Brad Dabbert, Robin Verble-Pearson Nov 2017

Response Of Northern Bobwhites To Habitat Improvement On Private Lands In The Rolling Plains Of Texas, C. Brad Dabbert, Robin Verble-Pearson

National Quail Symposium Proceedings

Northern bobwhites (Colinus virginianus) in the Rolling Plains of Texas have experienced significant declines in recent years. Examination of the Texas Parks and Wildlife Department Quail Roadside Counts reveals a steep decline since 2007 in the Rolling Plains of Texas. Biologists only detected 2.91 birds/counting route in 2013. This number marked 2 years in a row of record lows (counts started in 1978) below the long-term mean of 19.7 birds/route (Texas Parks and Wildlife 2015). These numbers are not surprising given the historically damaging drought Texas has suffered. Texas Parks and Wildlife Department counts improved to 7.5 bobwhites/counting …

A Focused Habitat Approach For Northern Bobwhite Restoration In Kentucky, John J. Morgan, John M. Yeiser, Danna L. Baxley, Gary Sprandel, Ben A. Robinson, Keith Wethington Nov 2017

A Focused Habitat Approach For Northern Bobwhite Restoration In Kentucky, John J. Morgan, John M. Yeiser, Danna L. Baxley, Gary Sprandel, Ben A. Robinson, Keith Wethington

National Quail Symposium Proceedings

The Kentucky Department of Fish and Wildlife Resources has measured northern bobwhite (Colinus virginianus) population trends since 1960. During that span, northern bobwhite steadily declined because clean agriculture, fescue-sod, plant succession, and development eroded habitat suitability. Multiple efforts have failed with regard to restoring northern bobwhite numbers. Over 3.5 million northern bobwhite were released by the Department over a three decade period. Habitat efforts on private lands were deployed for over 20 years with mixed results. Support for the habitat restoration efforts waned. In 2008, the Department unveiled a new strategy centered on restoring concentrated habitat in focal …

National Quail Symposium Proceedings

Northern bobwhite (Colinus virginianus) abundance has declined precipitously for decades across much of the species range, to the point of widespread local, regional, and statewide extirpation. Because of successful translocations of other gallinaceous birds, bobwhite enthusiasts increasingly call for use of the approach. Consequently, the National Bobwhite Technical Committee (NBTC), on behalf of state agencies, requested a review and recommendation by the NBTC Science Subcommittee. Thus, our paper is co-authored by invited experts and includes reviews of peer-reviewed publications, manuscripts in these proceedings, state agency reports, experience by co-authors, and a survey of perspectives on translocations by state …

Modeling Aggregation Of Proliferating Microglia In Response To Amyloid-Beta In Dementia, Adrienne C. Kinney, Ellen R. Swanson Nov 2017

Modeling Aggregation Of Proliferating Microglia In Response To Amyloid-Beta In Dementia, Adrienne C. Kinney, Ellen R. Swanson

Spora: A Journal of Biomathematics

Amyloid-beta plaques are prominent biological markers in dementia brains. In response to plaque formation, the brain's immune cells, microglia, become reactive. Microglia are measurable cells that surround amyloid-beta plaques, indicating their location. A system of partial differential equations describes the concentration of microglia in dementia brains by incorporating chemotactic signaling. However, this system fails to incorporate increasing numbers of reactive microglia cells in response to amyloid-beta aggregation. A system of ordinary differential equations describing the number of significant cells and proteins in the brain suggests the amount of reactive microglia increases significantly during the progression of dementia. We couple these …

Wildland Resources Faculty Publications

Our study aimed to delineate seasonal habitats and assess differential fitness related to migration strategy and seasonal habitat use of greater sage‐grouse (Centrocercus urophasianus, hereafter “sage‐grouse”). In addition, we evaluated benefits gained for sage‐grouse through the implementation of the Wyoming Core Area Strategy relative to protection of habitat and differences in nest, brood, and annual female survival. We compared the proportion of seasonal habitats that were within or outside Core Areas as delineated with 75% and 95% kernel density contours (KDE). The proportion of summer and winter habitats (95% KDE) that overlapped Core Areas was 0.69 of summer and 0.50 …

The Impact Of Integrated Delivery On Undergraduate Biology Research Course Outcomes, Claudia Knezek, Roxie James Nov 2017

The Impact Of Integrated Delivery On Undergraduate Biology Research Course Outcomes, Claudia Knezek, Roxie James

NERA Conference Proceedings 2017

At Kean University, Adaptive Teaching Taxonomy (AT) methodology was previously used in research courses to expand traditional lecture based instruction. This approach had been restrictive since targeted teaching methods did not fully address student learning needs in the classroom. In spring 2017, an integrated electronic learning approach was piloted in Senior Biology Capstone sections. It was proven effective, since students in the electronically enhanced Capstone courses had earned higher final grades than those attending traditional sections. SPSS t-test results were significant at .01 with Electronic Delivery yielding a higher mean score (3.6/4.0) than Traditional Delivery (2.26/4.0) results.

The Intrigue Of Paradigmatic Similarity: Leibniz And China, Yu Liu Nov 2017

The Intrigue Of Paradigmatic Similarity: Leibniz And China, Yu Liu

Comparative Civilizations Review

The cosmology of China is indeed strikingly similar to the metaphysics of Leibniz, but precisely where the two resemble each other, the former is unmistakably different from Christianity. Scholars of Leibniz have so far generally taken it for granted that he was ideologically aligned with Christianity, but his paradigmatic similarity to China should alert us of a surprisingly different story. Leibniz was indisputably “the greatest of the seventeenth century sinophiles” and key Chinese cosmological ideas were introduced to Europe long before he formulated his worldview. Together, these two facts can help us decide whether he “owes to Chinese organic naturalism …
