Phenological Mismatch Is Correlated With Fitness Outcomes And Adaptive Behavior In A Generalist Avian Predator Distributed Across North America, Kathleen R. Callery Aug 2020

Phenological Mismatch Is Correlated With Fitness Outcomes And Adaptive Behavior In A Generalist Avian Predator Distributed Across North America, Kathleen R. Callery

Boise State University Theses and Dissertations

Climate-driven advances in the start of spring may result in a phenological mismatch between peak-prey abundance and the breeding season of secondary consumers. Phenological mismatch has been well-studied in insectivorous birds for which reproductive productivity is strongly linked to caterpillar abundance. The effects of mismatch on the productivity of dietary generalists, that forage on several types of prey, are less well-understood. Further, few studies have addressed questions about the effects of mismatch on survival, an important component of fitness that can be affected by breeding in sub-optimal conditions. We examined the relationship between phenological mismatch and fitness for a widespread …


Testing Flowering Perennial Plants In A Bermudagrass (Cynodon Spp.) Lawn, Paige Elizabeth Boyle, Michelle Wisdom Aug 2020

Testing Flowering Perennial Plants In A Bermudagrass (Cynodon Spp.) Lawn, Paige Elizabeth Boyle, Michelle Wisdom

Horticulture Faculty Publications and Presentations

Most pollinating insects require a season-long succession of floral resources to fulfill life-cycle requirements. Incorporating forbs into turfgrass sites may create a season-long sequence of flowers to support foraging pollinators. However, persistence of forbs in warm-season turfgrasses such as bermudagrass (Cynodon spp.) may be affected by the competitive nature of the turfgrass and routine management practices such as mowing. A 2-year study was conducted to evaluate seven forbs (Bellis perennis L., Lotus corniculatus L., Prunella vulgaris L., Trifolium fragiferum L. ‘Fresa’, Trifolium repens L. ‘Durana’ and ‘Resolute’, Trifolium subterraneum L.) for persistence and ability to produce floral resources …


Patterns And Drivers In Counts Of Migratory Raptors At Hawk Mountain Sanctuary, Usa, Patricia Kaye Tahura Dumandan Aug 2020

Patterns And Drivers In Counts Of Migratory Raptors At Hawk Mountain Sanctuary, Usa, Patricia Kaye Tahura Dumandan

Boise State University Theses and Dissertations

Understanding the mechanisms driving biodiversity patterns amidst an era of global environmental change is the core of modern ecological research. The magnitude of biodiversity losses associated with anthropogenic activities has prompted resource managers and ecologists alike to identify strategies to address conservation issues. Broadly, two types of approaches are employed to answer ecological research questions: 1) single-species and 2) ecosystem-based approach. Single-species approaches are often useful to elucidate mechanisms driving population trajectories of individual species. On the other hand, ecosystem-based approaches can help in identifying general patterns that may be useful for multi-species management.

Here, I used both approaches in …

Interrelationships Among Monorchiid Trematodes With Special Emphasis On Some Northwestern Atlantic Genera, Apryle Panyi Aug 2020

Interrelationships Among Monorchiid Trematodes With Special Emphasis On Some Northwestern Atlantic Genera, Apryle Panyi

Master's Theses

The Monorchiidae Odhner, 1911 is a cosmopolitan family of flukes (Trematoda: Digenea) comprising species that parasitize the digestive tract of estuarine and marine fishes as adults. Compared with other oceans, recent morphological or molecular taxonomic work conducted on monorchiid species from the northwestern Atlantic Ocean has been sparse (Manter, 1931; Overstreet, 1969; Andres et al., 2018; Wee et al., 2018, 2019, 2020). Therefore, the present work investigated the interrelationships of some monorchiids from the northwestern Atlantic Ocean with emphasis on several genera and investigated if Lasiotocus minutus (Manter, 1931) Thomas, 1959 constitutes a complex of cryptic species. New morphological and …


Evaluating The Effect Of The Removal Of Non-Native Trout In Two High Elevation Tributary Streams In The Intermountain West, Clint Brunson Aug 2020

Evaluating The Effect Of The Removal Of Non-Native Trout In Two High Elevation Tributary Streams In The Intermountain West, Clint Brunson

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Native fish species such as Bonneville Cutthroat Trout (BCT) require cold, clear, well-connected streams for spawning and rearing as well as access to complimentary habitats. Increasing river temperatures and lower water flows may have allowed non-native Brown Trout (BNT) to migrate into higher elevation pristine streams. Additionally, anthropogenic actions such as stocking non-native Brown and Brook (BKT) and Rainbow Trout (RBT) for angling opportunities impact BCT. Invasion of these tributaries by non-native species may reduce or eliminate cutthroat trout by predation, competition, displacement, genetic suppression, and exclusion. A seven-fold increase in BNT numbers of 50 to 350 from 2017 to …


Improving Our Ability To Estimate Vital Rates Of Endangered Fishes On The San Juan River Using Novel Applications Of Pit-Tag Technology, J. Benjamin Stout Aug 2020

Improving Our Ability To Estimate Vital Rates Of Endangered Fishes On The San Juan River Using Novel Applications Of Pit-Tag Technology, J. Benjamin Stout

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Estimating demographic parameters, such as survival and abundance, with accuracy and precision is vital for detecting trends in populations and assessing the effectiveness of management actions. In most cases, a lack of capture data make estimating parameters very challenging. The use of new technologies to increase the amount of remotely collected data is increasing, but brings new limitations and analytical issues to be resolved. One of those new technologies is the use of a mobile floating PIT-tag antenna to detect PIT-tagged fish. The issue that arises with this technology is determination of the status of detected tags (i.e., live fish …


Ecology And Economic Impact Of The Invasive Brown Marmorated Stink Bug (Hemiptera: Pentatomidae; Halyomorpha Halys) In The Utah Agricultural Landscape, Zachary R. Schumm Aug 2020

Ecology And Economic Impact Of The Invasive Brown Marmorated Stink Bug (Hemiptera: Pentatomidae; Halyomorpha Halys) In The Utah Agricultural Landscape, Zachary R. Schumm

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The brown marmorated stink bug (BMSB) is a major insect pest that causes economic loss to a diversity of U.S. fruit and vegetable crops, and invades homes and human structures, causing nuisance issues for homeowners. This destructive insect causes millions of dollars of crop damage annually, and is difficult to manage due to its resistance to some common insecticides. BMSB is a relatively new pest to Utah, and its biology and ecology is not well known in the high elevation, arid Intermountain West region. In Chapter II, I explored the potential impact of BMSB to tart cherry, an unstudied crop …


A Data-Driven Regional Model Of Stomatal Conductance For Kruger National Park, Rebecca L. Tobin Aug 2020

A Data-Driven Regional Model Of Stomatal Conductance For Kruger National Park, Rebecca L. Tobin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Stomata are the gateway between the lithosphere, the biosphere, and the atmosphere. Because of photosynthesis, plants inevitably lose water through their stomata. The rate at which water moves through stomata is stomatal conductance. As stomatal conductance increases, the rate of CO2 assimilation increases, therefore, plants must reach a balance between acquiring CO2 and losing H2O. Plants achieve this balance by adjusting stomatal aperture. Therefore, modeling stomatal conductance is important to global circulation models and land surface models, as well as for predicting how changing climate conditions affect water use efficiency and plant productivity, and has implications …


Harmful Algal Blooms: Dominance In Lakes And Risk For Cyanotoxin Exposure In Food Crops, Austin D. Bartos Aug 2020

Harmful Algal Blooms: Dominance In Lakes And Risk For Cyanotoxin Exposure In Food Crops, Austin D. Bartos

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Climate change and human activities are promoting the dominance of a photosynthetic family of aquatic bacteria, cyanobacteria. Blooms of cyanobacteria are not only a visual nuisance but can produce a variety of cyanotoxins than can harm the liver, skin, and nervous system of animals and humans. We analyzed lakes in the contiguous United States and found that between 2007 and 2012, the number of lakes that produced measurable quantities of cyanotoxins increased from 33% to 45%. Nitrogen and phosphorus pollution were the main drivers of cyanobacteria blooms and toxin production between these years. Many of these lakes and reservoirs are …


Harvest Efficiency Of Forage Grazed By Cattle And The Effect Of Pinyon And Juniper Treatments On Vegetation Cover On The Grand Staircase Escalante National Monument, Ruger P. Carter Aug 2020

Harvest Efficiency Of Forage Grazed By Cattle And The Effect Of Pinyon And Juniper Treatments On Vegetation Cover On The Grand Staircase Escalante National Monument, Ruger P. Carter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Grand Staircase Escalante National Monument (GSENM), located in central south Utah, currently has 76,957 active grazing animal unit months on the monument. Recently, there has been questions whether the harvest and grazing efficiency coefficients developed in the Midwest are applicable to the arid, bunch grass dominated systems of the GSENM. Harvest and grazing efficiency defines the percentage of allocated forage that is being ingested by the animal, and the percentage that is being wasted. Harvest and grazing efficiency coefficients were calculated on the Lower Cattle allotment on the GSENM by taking total forage production and dividing that by expected …


Anthropogenic Influences On Bacterial Assemblages In Stream Biofilms, Elizabeth M. Ogata Aug 2020

Anthropogenic Influences On Bacterial Assemblages In Stream Biofilms, Elizabeth M. Ogata

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Bacteria within biofilms are an essential component of stream ecosystems, influencing the movement of carbon (C), nitrogen (N), and phosphorus (P) in watersheds. To better understand the ecological effects of human activities on stream ecosystems, my research examined how nutrients and pharmaceuticals, common pollutants in streams worldwide, influence bacterial assemblages in stream biofilms. First, I tested how nutrients (N, P, iron) and pharmaceuticals (caffeine, diphenhydramine) influenced biofilm bacterial microbiomes (taxa present in at least 75% of samples of a contaminant treatment). Nutrients allowed taxa known for their ability to thrive in nutrient-rich environments to dominate microbiomes, pharmaceuticals supported a rich …


Impacts Of Tourism On The Ecophysiology Of The Endangered Northern Bahamian Rock Iguana (Cyclura Cychlura), Alison C. Webb Aug 2020

Impacts Of Tourism On The Ecophysiology Of The Endangered Northern Bahamian Rock Iguana (Cyclura Cychlura), Alison C. Webb

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Increased interest in ecotourism over recent years has led to more direct human-animal interactions and a striking concomitant increase in the provisioning of non-natural food, that may have unintended consequences for the wildlife involved. The critically endangered Northern Bahamian Rock Iguana provides a valuable model to address the potential impact of food provisioning on health as there are populations that represent a graded variation in human presence, with sites experiencing high, low, or no tourism. To assess the potential impacts of tourism on iguana physiology I first reviewed the relevant literature on iguana physiology and then performed three investigations focusing …


Improving Aquatic Habitat Representation In Utah Using Large Spatial Scale Environmental Datasets, Gregory C. Goodrum Aug 2020

Improving Aquatic Habitat Representation In Utah Using Large Spatial Scale Environmental Datasets, Gregory C. Goodrum

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Rivers provide habitat for aquatic species, but widespread human water development degrades aquatic habitat, fragments stream networks, and threatens native fish populations. Habitat suitability models are commonly used to identify current instream habitat conditions, but are often species-specific, data-intensive, and rarely suitable to the large spatial scales required in conservation and water resources management. Thus, there is need to develop and validate habitat suitability models that provide ecologically-meaningful estimations of aquatic habitat, but are simple enough to apply at large geographic areas and flexible to incorporate different species. I tested the accuracy of 15 habitat suitability models estimating Bonneville Cutthroat …


Ecoacoustic Methods For Multi-Taxa Animal Surveys In The Amazon, Leandro A. Do Nascimento Aug 2020

Ecoacoustic Methods For Multi-Taxa Animal Surveys In The Amazon, Leandro A. Do Nascimento

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Tropical regions host most of the biodiversity found on Earth, but these species-rich areas are constantly threatened by human development and other disturbances that put this diversity of life forms at risk. To avoid extirpations of animal and plant species, scientists and managers rely on accurate monitoring techniques to retrieve information about population trends. This task is not easy, especially in the tropics, where there is often a lack of personnel to conduct surveys, a lack of funding, and the areas are so extensive that many countries need to be involved in monitoring (e.g., Amazon biome). For this reason, scientists …


Impact Of Disturbance Regimes On Community And Landscape Biodiversity In Atlantic Coastal Pine Barren Ecoregion Streams, Sean T. Mccanty Aug 2020

Impact Of Disturbance Regimes On Community And Landscape Biodiversity In Atlantic Coastal Pine Barren Ecoregion Streams, Sean T. Mccanty

Graduate Doctoral Dissertations

Streams are dynamic systems shaped by geographic location, hydrology, riparian vegetation, and in-stream habitat. Furthermore, ecosystem disturbance plays a major role in structuring stream communities and ecosystem processes. Disturbances include natural occurrences, such as flooding, drought, and fire events and anthropogenic disturbances such as land use changes, damming, and pollution. Agricultural use acts as a press disturbance regime, homogenizing the surrounding landscape and simplifying in-stream habitat, leaving legacy effects after farming ceases. Active restoration is intended to ameliorate these effects by reintroducing variation, with the goal of shifting the ecosystem into a more diverse and natural state. The act of …

Beetles (Coleoptera) In Cones Of Cycads (Cycadales) Of The Northern Hemisphere: Diversity And Evolution, William Tang, Guang Xu, Thomas Marler, Jibankumar Singh Khuraijam, Rita Singh, Anders J. Lindström, P. Radha, Stephen Rich, Khang Sinh Nguyen, Paul E. Skelley

Insecta Mundi

Three groups of beetles inhabit cones of cycads (Cycadales) in the northern hemisphere and are believed to be involved in their pollination. The primitive weevil subtribe Allocorynina (Coleoptera: Belidae) is restricted to the New World cycad genera Dioon Lindl. and Zamia L. One group of weevils (Curculionidae), found only in Cycas L., appears to be a relatively recent colonizer of northern hemisphere cycads. Members of the beetle subfamily Pharaxonothinae (Erotylidae) occur in all Asian and New World cycad genera. Phylogenetic trees of these beetles, based on DNA analysis and supported with morphological studies, are compared to patterns of continental drift …

First Record Of The Orchid Bee Euglossa Dilemma (Hymenoptera: Apidae) In Hispaniola, The Antilles, Julio A. Genaro, Ismael A. Hinojosa-Díaz, Lisa Mcdowell Johnson

Insecta Mundi

The occurrence of the orchid bee Euglossa dilemma Bembé and Eltz (Hymenoptera: Apidae) is recorded for the first time for the island of Hispaniola in the Greater Antilles. Males were observed visiting varieties of sweet basil plants (Ocimum basilicum Linnaeus (Lamiaceae)) to obtain fragrances used during courtship and reproduction. Our observations showed that the species is established in Hispaniola and that it does not require the presence of orchids for reproductive success, being able to adapt to new plant resources it finds in the areas it colonizes. These observations correspond to what was found in Florida, United States, where …

Spatial Ecology And Resource Selection Of Bighorn Sheep (Ovis Canadensis) Ewes In A Prairie Badlands Population, Erin Wood Jul 2020

Spatial Ecology And Resource Selection Of Bighorn Sheep (Ovis Canadensis) Ewes In A Prairie Badlands Population, Erin Wood

School of Natural Resources: Dissertations, Theses, and Student Research

The basic spatial ecology and habitat relationships of female bighorn sheep in Nebraska are poorly understood. Establishing seasonal patterns of space use and resource selection for this population at the margin of their historical and current range addresses a key knowledge gap and provides important baseline information for ongoing conservation efforts in Nebraska. We deployed GPS radio-collars on 56 adult ewes in western Nebraska to quantify seasonal space use, movements, and resource selection of ewes. To investigate spatial ecology, we quantified movements of ewes and the factors that influence home range size, seasonal use, and spatial stability across seasons. Home …

Shifts In The Microbiota Associated With Male Mosquitoes (Aedes Aegypti) Exposed To An Obligate Gut Fungal Symbiont (Zancudomyces Culisetae), Jonas Frankel-Bricker

University Author Recognition Bibliography: 2020

Research characterizing arthropod-associated microbiota has revealed that microbial dynamics can have an important impact on host phenotypic traits. The influence of fungi on these interactions are emerging as targets for research, especially in organisms associated with global human health. A recent study demonstrated colonization of a widespread gut fungus (Zancudomyces culisetae) in a larval mosquito (Aedes aegypti) digestive tract affected microbiomes in larvae and newly emerged adult females (Frankel-Bricker et al. Appl Environ Microbiol, 2020. https://doi.org/10.1128/AEM.02334-19) but did not investigate these processes in males. The objective of the study presented here was to assess fungal influences …

Snowy Plover Activity In The Central Platte River Valley In May 2019, Bethany L. Ostrom, Andrew J. Caven, Jenna M. Malzahn, Alyx Vogel

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

During five of eight site visits between 14 and 27 May 2019 we detected up to four Snowy Plovers (Charadrius nivosus nivosus) in the Central Platte River Valley (CPRV) near Mormon Island, Hall County, Nebraska, and recorded their behavior using an instantaneous scan sampling approach. We recorded loafing (47%), foraging (43%), mating (4%), flying (4%), and external threat (1%) related behavior. Most notably, we documented a copulation event on 23 May. During the 10-day span from 14 to 23 May when Snowy Plovers were detected, river stage and discharge were near median levels, but from 23 to 27 …


Consider The Agent In The Arthropod, Nicolas Delon, Peter Cook, Gordon Bauer, Heidi Harley Jul 2020

Consider The Agent In The Arthropod, Nicolas Delon, Peter Cook, Gordon Bauer, Heidi Harley

Animal Sentience

Whether or not arthropods are sentient, they can have moral standing. Appeals to sentience are not necessary and retard progress in human treatment of other species, including invertebrates. Other increasingly well-documented aspects of invertebrate minds are pertinent to their welfare. Even if arthropods are not sentient, they can be agents whose goals—and therefore interests—can be frustrated. This kind of agency is sufficient for moral status and requires that we consider their welfare.


What Is The Storage Effect, Why Should It Occur In Cancers, And How Can It Inform Cancer Therapy?, Anna K. Miller, Joel S. Brown, David Basanta, Nancy Huntly Jul 2020

What Is The Storage Effect, Why Should It Occur In Cancers, And How Can It Inform Cancer Therapy?, Anna K. Miller, Joel S. Brown, David Basanta, Nancy Huntly

Ecology Center Publications

Intratumor heterogeneity is a feature of cancer that is associated with progression, treatment resistance, and recurrence. However, the mechanisms that allow diverse cancer cell lineages to coexist remain poorly understood. The storage effect is a coexistence mechanism that has been proposed to explain the diversity of a variety of ecological communities, including coral reef fish, plankton, and desert annual plants. Three ingredients are required for there to be a storage effect: (1) temporal variability in the environment, (2) buffered population growth, and (3) species-specific environmental responses. In this article, we argue that these conditions are observed in cancers and that …
