Bryophyte Diversity Is Related To Vascular Plant Diversity And Microhabitat Under Disturbance In Karst Caves, Hai Ren, Faguo Wang, Wen Ye, Qianmei Zhang, Taotao Han, Yao Huang, Guowei Chu, Dafeng Hui, Qinfeng Guo

Biology Faculty Research

Plant diversity, habitat properties, and their relationships in karst caves remain poorly understood. We surveyed vascular plant and bryophyte diversities and measured the habitat characteristics in six karst caves in south China with different disturbance histories (one had been disturbed by poultry feeding, three had been disturbed by tourism, and two were undisturbed). The plant diversity differences among the six caves were analyzed using cluster analysis, and the relationships of plant diversity and microhabitat were assessed using canonical correspondence analysis. We found a total of 43 angiosperm species from 27 families, 20 lycophyte and fern species from 9 families, and …

Evolution Of Breeding Plumages In Birds: A Multiple-Step Pathway To Seasonal Dichromatism In New World Warblers (Aves: Parulidae), Ryan S. Terrill, Glenn F. Seeholzer, Jared D. Wolfe Sep 2020

Evolution Of Breeding Plumages In Birds: A Multiple-Step Pathway To Seasonal Dichromatism In New World Warblers (Aves: Parulidae), Ryan S. Terrill, Glenn F. Seeholzer, Jared D. Wolfe

Michigan Tech Publications, Part 1

Ecology and Evolution published by John Wiley & Sons Ltd Many species of birds show distinctive seasonal breeding and nonbreeding plumages. A number of hypotheses have been proposed for the evolution of this seasonal dichromatism, specifically related to the idea that birds may experience variable levels of sexual selection relative to natural selection throughout the year. However, these hypotheses have not addressed the selective forces that have shaped molt, the underlying mechanism of plumage change. Here, we examined relationships between life-history variation, the evolution of a seasonal molt, and seasonal plumage dichromatism in the New World warblers (Aves: Parulidae), a …

Description Of The Male Of Wernerius Mumai (Sissom, 1993) From Western Arizona, With Data On Reproduction (Scorpiones: Vaejovidae), Richard F. Ayrey, Brandon T. Myers

Euscorpius

A male of Wernerius mumai (Sissom, 1993) is described for the first time, collected at the type locality (Gold Road, Black Mountains, Mohave County, Arizona). Originally placed in the genus Vaejovis, this species later was transferred by Soleglad & Fet (2008) to the genus Wernerius. It is one of the smallest vaejovid species known. The pedipalp fixed finger usually has 6 ID denticles and the movable finger has 7. The most unique characteristic of this species is the long, pointed, subaculear tubercle.

Integrative Species Delimitation And Taxonomic Status Of The Scorpion Genus Vaejovis Koch, 1836 (Vaejovidae) In The Santa Catalina Mountains, Arizona, Emma E. Jochim, Lillian-Lee M. Broussard, Brent E. Hendrixson

Euscorpius

Scorpions belonging to the Vaejovis vorhiesi species complex are widely distributed throughout the southwestern United States and northern Mexico. Most species are endemic to single mountain ranges but two species, Vaejovis deboerae Ayrey, 2009 and V. brysoni Ayrey & Webber, 2013, have been documented from the Santa Catalina Mountains in Arizona. We reevaluated the taxonomic diversity of these scorpions by integrating data from several different sources. Phylogenetic analyses indicate that scorpions in the Santa Catalina Mountains are monophyletic but comprise two divergent mitochondrial lineages that overlap at the type locality of V. deboerae. We failed to detect congruence between …

Assessment Of Wild Ring-Tailed Lemur (Lemur Catta) Populations In Southwestern Madagascar With Implications For The Illegal Pet Trade, Samantha D. Calkins Aug 2020

Assessment Of Wild Ring-Tailed Lemur (Lemur Catta) Populations In Southwestern Madagascar With Implications For The Illegal Pet Trade, Samantha D. Calkins

Theses and Dissertations

Accurate population estimates are critical to inform conservation management of species. Incomplete sampling can lead to population underestimates and lacking conservation efforts. Population surveys are important for assessing human and animal welfare to allow for targeted conservation action. Recent ring-tailed lemur (Lemur catta) surveys have led researchers to conclude that L. catta populations are crashing. This has generated much attention and alarm, but may also be based on incomplete information. To better understand population dynamics, more thorough sampling is needed. Here, we survey five such sites to reassess the presence and abundance of L. catta in these locations. …

Documenting West And Central African Dung Beetle (Coleoptera: Scarabaeinae) Community Structures And Their Vulnerability To Climate Change, Christie A. Sukhdeo Aug 2020

Documenting West And Central African Dung Beetle (Coleoptera: Scarabaeinae) Community Structures And Their Vulnerability To Climate Change, Christie A. Sukhdeo

LSU New Orleans Theses and Dissertations

The Guineo-Congolian (GC) region of West and Central Africa contains high levels of species richness (SR) and endemism. Within the GC region, the Cameroon Volcanic Line (CVL) is an important biodiversity hotspot in part due to montane habitats that constitute important ‘sky islands’ refugia during warm periods of the Pleistocene glacial cycles. However, little is known about the diversity of many taxa in the GC region, especially for insects. The main goals of this dissertation are to: 1) document dung beetle (Coleoptera: Scarabaeinae) species diversity across the GC region and assess the potential impacts of future climate change on species …

Heterotrophic Carbon Fixation In A Salamander-Alga Symbiosis, John A. Burns, Ryan Kerney, Solange Duhamel Aug 2020

Heterotrophic Carbon Fixation In A Salamander-Alga Symbiosis, John A. Burns, Ryan Kerney, Solange Duhamel

Biology Faculty Publications

The unique symbiosis between a vertebrate salamander, Ambystoma maculatum, and unicellular green alga, Oophila amblystomatis, involves multiple modes of interaction. These include an ectosymbiotic interaction where the alga colonizes the egg capsule, and an intracellular interaction where the alga enters tissues and cells of the salamander. One common interaction in mutualist photosymbioses is the transfer of photosynthate from the algal symbiont to the host animal. In the A. maculatum–O. amblystomatis interaction, there is conflicting evidence regarding whether the algae in the egg capsule transfer chemical energy captured during photosynthesis to the developing salamander embryo. In experiments …

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 …

Feral Swine, Michael P. Glow, Nathan P. Snow, Kurt C. Vercauteren Aug 2020

Feral Swine, Michael P. Glow, Nathan P. Snow, Kurt C. Vercauteren

Wildlife Damage Management Technical Series

Feral swine (Sus scrofa; Figure 1), also known as feral hogs, feral pigs, wild pigs, wild boar, or other similar derivations, are a non-native species considered to be one of the most destructive invasive terrestrial vertebrates in North America. While feral swine populations remained relatively small and confined in the continental United States following initial introductions by European explorers during the 15th century, substantial range expansion has occurred across every geographical region of the United States (Figure 2). This expansion has primarily been attributed to human-mediated movements, predominately for the purpose of establishing populations for recreational hunting, and facilitated by …

Urban Air Quality Modeling: Evaluating Impacts Of Ecoroofs On Urban Air Quality In Portland, Oregon, Danlyn L. Brennan, Selina Teng Aug 2020

Urban Air Quality Modeling: Evaluating Impacts Of Ecoroofs On Urban Air Quality In Portland, Oregon, Danlyn L. Brennan, Selina Teng

altREU Projects

In this work, the authors present a mathematical model simulating the impact of ecoroof vegetation on air quality in an urban microclimate. An ecoroof is a layer of vegetation established on rooftops to reduce stormwater runoff, mitigate heat, and enhance air quality. Certain plant species in ecoroofs may however have a detrimental effect on air quality, due to their emission of biogenic volatile organic compounds (BVOCs), which include potentially reactive species such as isoprene. These chemical species can interact with urban air pollution, particularly NOx produced by car traffic, to create other harmful pollutants such as ozone and particulate matter …

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 …

Plant Diversity And Nitrogen Addition On Belowground Biodiversity And Soil Organic Carbon Storage In Biofuel Cropping Systems, Jennifer Butt Aug 2020

Plant Diversity And Nitrogen Addition On Belowground Biodiversity And Soil Organic Carbon Storage In Biofuel Cropping Systems, Jennifer Butt

Boise State University Theses and Dissertations

Bioenergy production may reduce the emission of CO2 which contributes to climate change, particularly when management strategies are adopted that promote soil carbon (C) sequestration in bioenergy cropping systems. Planting perennial native grasses, such as switchgrass (Panicum virgatum L.) and big bluestem (Andropogon gerardii Vitman) may be used as a strategy to enhance soil C accumulation owing to their extensive root systems. Fertilizer use may further promote soil C sequestration, because of its positive impacts on plant production and soil C input. However,, the influence of fertilizer addition on soil C accumulation is variable across bioenergy cropping …

Notes On The Diet And Reproduction Of The Bark Scorpion Centruroides Gracilis (Scorpiones: Buthidae) On Utila Island, Honduras, Anna M. Davison, Tom W. Brown, Cristina Arrivillaga Jul 2020

Notes On The Diet And Reproduction Of The Bark Scorpion Centruroides Gracilis (Scorpiones: Buthidae) On Utila Island, Honduras, Anna M. Davison, Tom W. Brown, Cristina Arrivillaga

Euscorpius

The brown bark scorpion Centruroides gracilis (Latreille, 1804) (Buthidae) is an abundant and widespread species, however, fairly little is known about its ecology and natural history. We include several observations from Utila Island, Honduras, that expand on the known literature regarding the diet and reproductive behavior of C. gracilis. We report several prey items for this opportunistic species, which include invertebrates such as spiders (including tarantulas), centipedes, katydids, and crickets; as well as a case of cannibalism between two adult females C. gracilis. We suggest that such cannibalism may be driven by high population densities and/or strong intraspecific …

Determination Of The Summer Origins Of American Kestrels ( Falco Sparverius ) Wintering In Northern And Central Illinois, Taylor P. Joray Jul 2020

Determination Of The Summer Origins Of American Kestrels ( Falco Sparverius ) Wintering In Northern And Central Illinois, Taylor P. Joray

Theses and Dissertations

The seasonal and interannual movements of the American Kestrel (Falco sparverius) are not fully understood. Although one of the most widespread and abundant raptors found in North America, information on where many populations summer and overwinter is lacking. We used stable hydrogen isotope values obtained from feathers (δ2Hf) of known origin to create age-specific calibration functions for juvenile and adult American Kestrels. We then used these calibration functions to determine the most likely summer origins of the American Kestrels that wintered in northern and central Illinois during 2015-16, classified these individuals as year-round residents or wintering migrants, and validated these …

A New Lesser Antillean Scorpion Of The Genus Didymocentrus Kraepelin, 1905 (Scorpiones: Diplocentridae), Rolando Teruel, Karl Questel

Euscorpius

A new species of the diplocentrid scorpion of the genus Didymocentrus Kraepelin, 1905 is herein described from the Lesser Antillean island of Martinique. It long remained misidentified as Didymocentrus lesueurii (Gervais, 1844), the only species of this genus inhabiting the adjacent island of Saint Lucia. The direct comparison of adults of both sexes from these two islands revealed solid morphological characters, which warrant their recognition as two different taxa. Each one is endemic from a single major island, where it is widespread even in its satellite islets. This addition raises the known composition of the genus to 12 species, 10 …
