Patterns And Sources Of Variation In Heterospecific Pollen Deposition In Flowers Of The Native Blue Cardinal Flower (Lobelia Siphilitica), Allie Drinnon 2023 East Tennessee State University

Patterns And Sources Of Variation In Heterospecific Pollen Deposition In Flowers Of The Native Blue Cardinal Flower (Lobelia Siphilitica), Allie Drinnon

Undergraduate Honors Theses

Plants species interactions via pollinators are a model system to understand the mechanisms that generate plant diversity in nature. However, most studies have focused on plant-plant interactions via pollinator attraction while ignoring the role of plant-plant interactions via pollen transfer. Heterospecific pollen transfer (henceforth HP) can be common and have negative fitness effects. Negative HP fitness effects may prompt the evolution of adaptive strategies to minimize them. However, the extent of spatial variation in HP load size within and among populations, a tenet for natural selection, remains unexplored. Such knowledge would hence constitute a first step in advancing our understanding ...


Potential Effects Of Road Proximity On Zooplankton Communities And Water Quality In Lakes In The Northwest Territories, Marie N. Hannan 2023 Wilfrid Laurier University

Potential Effects Of Road Proximity On Zooplankton Communities And Water Quality In Lakes In The Northwest Territories, Marie N. Hannan

Theses and Dissertations (Comprehensive)

Studies conducted along Canada’s Dempster Highway in the Northwest Territories have shown that road dust can affect water quality in roadside lakes, leading to higher calcium, conductivity, and pH levels. These water quality changes have the potential to affect important members of the lower aquatic food web, such as zooplankton.

For my thesis research, I had two main objectives: 1) To determine if changes in water chemistry caused by deposition of road dust affects zooplankton communities; and 2) To examine if the type of roadside vegetation influences the effects of road dust on aquatic habitats. To achieve these objectives ...


Avian Species Distribution Models: Using Location Data To Inform Management Decisions, Marilyn E. Wright 2022 Utah State University

Avian Species Distribution Models: Using Location Data To Inform Management Decisions, Marilyn E. Wright

All Graduate Theses and Dissertations

Both state and federal wildlife agencies strive to conserve and protect wildlife and their habitats as an important public resource. Applied management decisions often rely on being able to obtain data that can efficiently and effectively enhance the understanding of these systems for informing management actions. Wildlife managers often focus efforts on a small subset of species from an ecosystem, typically called focal species, who can serve as surrogates for understanding the health and function of the system. Models that consider how these focal species interact with the ecosystem are often used to better understand important aspects of their life ...


Rainfall Increases Alpha And Has No Effect On The Beta Diversity Of Animal-Dispersed Shrubs In Panama, Rosemary Hopson 2022 Utah State University

Rainfall Increases Alpha And Has No Effect On The Beta Diversity Of Animal-Dispersed Shrubs In Panama, Rosemary Hopson

All Graduate Theses and Dissertations

Climate patterns affect where plants can grow and survive. In tropical areas, the main form of precipitation is rain, and rainfall has been demonstrated to influence tree species distributions. For this thesis, I examined the relationship between rainfall and the diversity of animal-dispersed tropical shrubs. To do this, I used data on shrub diversity collected in the summer of 2017. Plots were established across the Isthmus of Panama, from the drier Pacific side to the wetter Atlantic side, to survey animal-dispersed shrubs. I analyzed three metrics of diversity that weigh rare and common species differently. The first weighs rare species ...

Based on the body of literature and available data, this species conservation assessment provides an overview of our current knowledge of timber ...


Report Of Thanatosis In The Central American Scorpions Tityus Ocelote And Ananteris Platnicki (Scorpiones: Buthidae), Felipe Triana, Fabián Bonilla, Adriana Alfaro-Chinchilla, Carlos Víquez, Cecilia Díaz, Mahmood Sasa 2022 Marshall University

Report Of Thanatosis In The Central American Scorpions Tityus Ocelote And Ananteris Platnicki (Scorpiones: Buthidae), Felipe Triana, Fabián Bonilla, Adriana Alfaro-Chinchilla, Carlos Víquez, Cecilia Díaz, Mahmood Sasa

Euscorpius

Thanatosis, or tonic immobility, is a behavior where animals adopt a motionless posture after a physical contact or very close proximity of a predator. This behavior has been described in a wide range of taxa, from invertebrates to vertebrates. For scorpions, tonic immobility has been reported in two buthids, Tityus pusillus and Tityus cerroazul, one hormurid, Liocheles australasiae, and one scorpiopsid, Scorpiops jendeki. Here we report other cases of this thanatosis for two buthid scorpions from lower Central America: Tityus ocelote and Ananteris platnicki. Thanatosis in these species were observed in wild, but was better documented in the laboratory. After ...

Ecological Implications Of Intraspecific Behavioral Variation In A Small Mammal Community, Allison Brehm 2022 University of Maine

Ecological Implications Of Intraspecific Behavioral Variation In A Small Mammal Community, Allison Brehm

Electronic Theses and Dissertations

Variation among individuals is at the root of all evolution by means of natural selection. However, only in recent years has intraspecific behavioral variation been embraced as a potential driver of community and ecosystem processes, rather than considered statistical noise. Animal personalities, or behavioral differences between conspecifics that are consistent across time and contexts, are one such form of variation that has received considerable attention in the last two decades. Investigations of the ecological and ecosystem consequences of personality variation is at the current forefront of the field, but much work on this topic remains conceptual. Here, I apply large-scale ...

The Evolution Of Quail Research: Trends In Themes, Cognitive Extent, And Lexical Diversity, Fidel Hernández

National Quail Symposium Proceedings

Language is an interesting characteristic that is unique to humans. Language represents a method of human communication and is believed to reflect a person’s view of reality (Kramsch 2004). The words used by a person or a community provide insight into the ideas, concepts, and worldview held by people (Pennebaker et al. 2003). In science, publications represent a primary form of communication of ideas among scientists. Publications provide a historical record of a discipline and reflect the relative interest of a scientific community in particular concepts during a given era (Kim et al. 2018). Consequently, how word use in ...


Effects Of Climate Change On Northern Bobwhite Nesting Chronology And Clutch Size, Justin A. Rectenwald, D. Clay Sisson, James A. Martin 2022 Tall Timbers Research Station Albany Quail Project

Effects Of Climate Change On Northern Bobwhite Nesting Chronology And Clutch Size, Justin A. Rectenwald, D. Clay Sisson, James A. Martin

National Quail Symposium Proceedings

Widespread changes to breeding bird phenology in response to climate change have been apparent in North America for several decades. While the impact of an earlier breeding season may be minimal by itself, changes in community-level interactions can be greatly influenced because of varying responses to climate change in different trophic levels. Climate change has been shown to alter the onset of breeding season and chick survival, and lead to population declines for game birds in high latitudes, at high elevations, and on the periphery of their range. The topic of climate change in relation to northern bobwhite (Colinus virginianus ...


Examining A Habitat-Weather Threshold For Northern Bobwhite Populations In The Southwestern United States, John T. Edwards, Fidel Hernández, Andrea Montalvo, Masahiro Ohnishi 2022 Caesar Kleberg Wildlife Research Institute

Examining A Habitat-Weather Threshold For Northern Bobwhite Populations In The Southwestern United States, John T. Edwards, Fidel Hernández, Andrea Montalvo, Masahiro Ohnishi

National Quail Symposium Proceedings

In semiarid portions of the northern bobwhite (Colinus virginianus; hereafter, bobwhite) geographic distribution, weather is a strong driver of interannual abundance. However, the strength of this relationship may depend on habitat amount. Given this habitat–weather dependence, there is likely to be a threshold value for habitat that determines how strongly a bobwhite population responds to weather. Our objective was to evaluate the relationship between habitat amount and the relative influence of weather on bobwhite abundance in Texas and Oklahoma, USA and determine a potential land-cover threshold value. We collected bobwhite abundance and land-cover data from the Breeding Bird Survey ...


Climate Impacts On North American Quail, Shelby M. Perry, Erin Moser, Jeffrey G. Whitt, Kelly S. Reyna 2022 Texas A&M University Commerce

Climate Impacts On North American Quail, Shelby M. Perry, Erin Moser, Jeffrey G. Whitt, Kelly S. Reyna

National Quail Symposium Proceedings

North America’s quail population trends are often linked to regional climate. Extreme climate events such as severe drought, hard freezes, or excessive winter precipitation can reduce quail populations by as much as 84%. Above-average spring and summer temperatures coincident with drought can reduce the laying season for quail by ≤60 days. Exposure of quail eggs to high temperatures during preincubation can initiate and alter embryonic development. Here, we review the impacts of extreme climate events and a changing climate on the survival, reproduction, and population trends of 6 North American quail species: California quail (Callipepla californica), Gambel’s quail ...

Northern Bobwhite Response To Control Of Red Imported Fire Ants In The Gulf Coast Prairie Of Texas, Kelly M. Redmond, Eric D. Grahmann, Fidel Hernández, Leonard A. Brennan, Michael E. Morrow, Timothy Anderson

National Quail Symposium Proceedings

The population decline of northern bobwhite (Colinus virginianus; hereafter, bobwhite) on the Texas Gulf Coast Prairie, USA is largely attributed to habitat loss. However, red imported fire ants (Solenopsis invicta) occur throughout the region and are considered a possible contributing factor to the bobwhite decline. The objectives of our study were to determine the influence of red imported fire ants on bobwhites by comparing bobwhite nest success, survival, and density between sites treated with fire ant bait (treatment) and reference (control) sites. Our study was conducted on 3 private ranches in Goliad and Refugio counties, Texas. Each ranch contained 2 ...

Northern Bobwhite And Fire: A Review And Synthesis, David A. Weber, Evan P. Tanner, Theron M. Terhune Ii, J. Morgan Varner, James A. Martin

National Quail Symposium Proceedings

Our understanding of the relationship between northern bobwhite (Colinus virginianus; hereafter, bobwhite) and fire began with Herbert Stoddard’s work in the early 20th century. Research on the topic has continued, but our application of fire is deeply rooted in Stoddard’s work, even as it has become evident that fire regimes must be adapted to variable environmental conditions that are evolving with a changing landscape and climate. A comprehensive review and synthesis of the literature on this topic would help formalize research advancements since Stoddard and identify knowledge gaps for future research. Results from experiments suggest fire creates favorable ...

Bobwhite Response To Cattle Grazing In South Texas, Bradley K. Johnston, J. Alfonso Ortega-S., Leonard A. Brennan, Fidel Hernández, Humberto L. Perotto-Baldivieso

National Quail Symposium Proceedings

Range management practices to improve habitat for wildlife by reducing brush and increasing herbaceous plants, coupled with reduced stocking rates, can lead to dense stands of dominant grasses, such as four-flower trichloris (Trichloris pluriflora). This monoculture of trichloris creates dense vegetation unsuitable for northern bobwhite (Colinus virginianus; hereafter, bobwhite), reduces plant species diversity, and alters ecosystem functions. The objectives of this study are to 1) evaluate the effects of a proper cattle grazing regime to improve bobwhite habitat and 2) develop a management guide documenting how cattle grazing can be used as a tool to reduce the density and cover ...


Northern Bobwhite Response To Vegetation Management And Recovery In South Texas, Rachel A. Smith, Leonard A. Brennan, Humberto L. Perotto-Baldivieso, Fidel Hernández 2022 Texas A&M University, Kingsville

Northern Bobwhite Response To Vegetation Management And Recovery In South Texas, Rachel A. Smith, Leonard A. Brennan, Humberto L. Perotto-Baldivieso, Fidel Hernández

National Quail Symposium Proceedings

The northern bobwhite (Colinus virginianus; hereafter, bobwhite) requires habitat structure and composition with grass cover for nesting, predator avoidance, and thermal refuge and forb cover for feeding on phytophagous arthropods and seeds. During the past 2 decades, many land managers with interest in promoting quail hunting opportunities have reduced or completely eliminated livestock across South Texas, USA, rangelands. Resting the land from grazing allows vegetation—especially grasses and forbs—to recover and thus provide nesting and foraging habitat for bobwhite and other birds. How bobwhite respond to postgrazing vegetation recovery is of keen interest to rangeland quail managers, but this ...


Efficacy Of A Preemergence Herbicide Following Postemergence Control To Reduce Sericea Lespedeza In Old Fields Managed For Northern Bobwhite, Mark A. Turner, Bonner L. Powell, Craig A. Harper 2022 University of Tennessee

Efficacy Of A Preemergence Herbicide Following Postemergence Control To Reduce Sericea Lespedeza In Old Fields Managed For Northern Bobwhite, Mark A. Turner, Bonner L. Powell, Craig A. Harper

National Quail Symposium Proceedings

Sericea lespedeza (Lespedeza cuneata; hereafter, sericea) is a nonnative forb that commonly invades sites managed for northern bobwhite (Colinus virginianus; hereafter, bobwhite). Sericea can reduce habitat quality for bobwhite as it outcompetes native plants that provide forage and cover. Bobwhite eat sericea seed, but seed are relatively indigestible and may limit nutrition intake and reduce the fecundity rate. Postemergence herbicides, including glyphosate, triclopyr, and fluroxypyr+triclopyr, control standing sericea, but do not provide preemergence control, which would increase long-term control because sericea annually produces large amounts of hard seed with high dormancy rates. Imazapic is labeled to provide preemergence control ...
