Caddisflies (Trichoptera) Of The Buffalo National River, Arkansas, David E. Bowles, Cameron Cheri, Faron D. Usrey, Jeffrey M. Williams

Insecta Mundi

We report 106 species of caddisflies (Trichoptera) representing 44 genera and 16 families that were collected across 50 sampling sites in the Buffalo River watershed. The species collected represent about 45% of the known Interior Highlands caddisfly fauna. The most speciose families collected were the Hydroptilidae (30), Leptoceridae (21), and Hydropsychidae (17). Two species found during this study, Paduniella nearctica and Ochrotrichia contorta, are listed as species of special concern in the state of Arkansas due to their relative rarity. Similarity analysis values among collection sites ranged from 9% to 77%. Seriation analysis of caddisfly genera and species showed …

Arcola Malloi (Pastrana), The Alligatorweed Stemborer, A New Synonym Of Macrorrhinia Endonephele (Hampson) (Lepidoptera: Pyralidae: Phycitinae), James E. Hayden, Jean-François Landry

Insecta Mundi

Arcola malloi (Pastrana, 1961) is a junior subjective synonym of Macrorrhinia endonephele (Hampson, 1918) syn. nov. (Lepidoptera: Pyralidae). The species is a biological control agent introduced in United States and Australia to control alligatorweed, Alternanthera philoxeroides (Mart.) Griseb. (Amaranthaceae). The synonymy is recognized by comparison of type specimens, genitalic dissections, and DNA COI barcoding. Vogtia Pastrana, 1961 syn. nov. and Arcola Shaffer, 1995 syn. nov. are synonymized with Macrorrhinia Ragonot, 1887. Macror­rhinia megajuxta (Neunzig and Goodson, 1992) comb. nov. is transferred from Ocala Hulst, 1892. Lectotypes are designated for Divitiaca ochrella Barnes and McDunnough, 1913, and Divitiaca simulella Barnes and …

Estimating The Potential Blue Carbon Gains From Tidal Marsh Rehabilitation: A Case Study From South Eastern Australia, Anne Gulliver, Paul E. Carnell, Stacey M. Trevathan-Tackett, Micheli Duarte De Paula Costa, Pere Masqué, Peter I. Macreadie

Research outputs 2014 to 2021

© Copyright © 2020 Gulliver, Carnell, Trevathan-Tackett, Duarte de Paula Costa, Masqué and Macreadie. Historically, coastal “blue carbon” ecosystems (tidal marshes, mangrove forests, seagrass meadows) have been impacted and degraded by human intervention, mainly in the form of land acquisition. With increasing recognition of the role of blue carbon ecosystems in climate mitigation, protecting and rehabilitating these ecosystems becomes increasingly more important. This study evaluated the potential carbon gains from rehabilitating a degraded coastal tidal marsh site in south-eastern Australia. Tidal exchange at the study site had been restricted by the construction of earthen barriers for the purpose of reclaiming …

Migratory Behavior And Winter Geography Drive Differential Range Shifts Of Eastern Birds In Response To Recent Climate Change, Clark S. Rushing, J. Andrew Royle, David J. Ziolkowski Jr, Keith L. Pardieck

Ecology Center Publications

Over the past half century, migratory birds in North America have shown divergent population trends relative to resident species, with the former declining rapidly and the latter increasing. The role that climate change has played in these observed trends is not well understood, despite significant warming over this period. We used 43 y of monitoring data to fit dynamic species distribution models and quantify the rate of latitudinal range shifts in 32 species of birds native to eastern North America. Since the early 1970s, species that remain in North America throughout the year, including both resident and migratory species, appear …

A Late Blancan Local Fauna From Northern Idaho, Marlena Blua, Jonathon Welch, Neville Magone

2020 Symposium Posters

Mammal specimens from a new Pleistocene-age locality near Priest River, Idaho have been identified from at least nine different taxa including muskrat, beaver, porcupine, deer, horse, pronghorn antelope, canid, lynx and bear. A right mandible containing i1 and m1-m2 is of an Ondatra sp. of muskrat. The m1is significantly shorter, narrower and the L/W ratio smaller than that of extant and extinct O. zebethicus. Yet the m1 length and width are both larger than either O. idahoensis and O. annectens. The beaver is represented by an isolated incisor, two lower molars and one upper molar. All three molars share the …

Storm Surges In The Bohai Sea: The Role Of Waves And Tides, Yuanyi Li, Huan Feng, Guillaume Vigouroux, Dekui Yuan, Guangyu Zhang, Xiaodi Ma, Kun Lei

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

A storm surge is a complex phenomenon in which waves, tide and current interact. Even though wind is the predominant force driving the surge, waves and tidal phase are also important factors that influence the mass and momentum transport during the surge. Devastating storm surges often occur in the Bohai Sea, a semi-enclosed shallow sea in North China, due to extreme storms. However, the effects of waves on storm surges in the Bohai Sea have not been quantified and the mechanisms responsible for the higher surges that affect part of the Bohai Sea have not been thoroughly studied. In this …

Genetic Biocontrol For Invasive Species, John L. Teem, Luke Alphey, Sarah Descamps, Matt P. Edgington, Owain Edwards, Neil Gemmell, Tim Harvey-Samuel, Rachel L. Melnick, Kevin P. Oh, Antoinette J. Piaggio, J. Royden Saah, Dan Schill, Paul Thomas, Trevor Smith, Andrew Roberts

United States Department of Agriculture Wildlife Services: Staff Publications

Invasive species are increasingly affecting agriculture, food, fisheries, and forestry resources throughout the world. As a result of global trade, invasive species are often introduced into new environments where they become established and cause harm to human health, agriculture, and the environment. Prevention of new introductions is a high priority for addressing the harm caused by invasive species, but unfortunately efforts to prevent new introductions do not address the economic harm that is presently manifested where invasive species have already become established. Genetic biocontrol can be defined as the release of organisms with genetic methods designed to disrupt the reproduction …

The Effect Of Intensified Illuminance And Artificial Light At Night On Fitness And Susceptibility To Abiotic And Biotic Stressors, Grascen Shidemantle

Biological Sciences Student Scholarship

Changing light conditions due to human activities represents an important emerging environmental concern. Although changes to natural light conditions can be independently detrimental, in nature, organisms commonly face multiple stressors. To understand the consequences of altered light conditions, we exposed a model amphibian (wood frog; Lithobates sylvaticus) to a control and two anthropogenic light conditions: intensified daytime illuminance and artificial light at night - ALAN (intensified daytime illuminance + extended photoperiod). We measured (1) metrics of fitness (hatching success as well as survival to, size at, and time to metamorphosis) (2) susceptibility (time to death) to a commonly cooccurring anthropogenic …

Size Selective Parasitism Of Rainbow Trout (Oncorhynchus Mykiss) By Chestnut Lampreys (Ichthyomyzon Castaneus) In An Artificial Setting, Jeremiah M. Salinger, Ronald L. Johnson

Southeastern Fishes Council Proceedings

Paradigms of optimal resource utilization by animals, both classical and more recent, were not originally developed in the context of parasitism. Though this oversight has slowly been reversed, little attention has been paid to optimal resource utilization by parasitic fishes, such as lampreys. Multiple explanations for host size selection by parasitic lampreys may be plausible, but results from previous studies have been inconsistent. We studied host size selection by Chestnut Lampreys (Ichthyomyzon castaneus) parasitizing Rainbow Trout (Oncorhynchus mykiss) in fish hatchery raceways in north central Arkansas during the late winter and early spring of 2013. Parasitized …

Movement Of Translocated Adult Sicklefin Redhorse (Moxostoma Sp.) In The Oconaluftee River, North Carolina: Implications For Species Restoration, Jessica L. Davis, David P. Gillette, C. Reed Rossell Jr., Michael J. Lavoie

Southeastern Fishes Council Proceedings

The Sicklefin Redhorse is a rare, undescribed species of Moxostoma, endemic to the Hiwassee and Little Tennessee River basins of western North Carolina and northern Georgia, where it has been eliminated from much of its native range. It is listed as endangered in Georgia and threatened in North Carolina. Although it has not been granted federal protected status, this species is the subject of a Candidate Conservation Agreement between federal, state, tribal, and private stakeholders, of which one objective calls for the re-establishment of Sicklefin Redhorse populations throughout its historical range. The objective of our study was to evaluate …

The Evolution Of Bivalve Shell Matrix Proteins, Mark Ira Duhon Ii

LSU Doctoral Dissertations

This dissertation focuses on the molecular underpinnings surrounding the evolution of the biomineralized shells of marine bivalves. Bivalve molluscs synthesize remarkably complex shells from calcium carbonate and an organic matrix of proteins secreted from the dorsal edge of the mantle. Molecular analyses of shell matrix proteins (SMPs) have suggested high rates of gene turnover despite the conserved nature of the shell itself. Here, I used proteomic and transcriptomic data to identify the SMPs and other biomineralization proteins from seven bivalve species that diverged 3-513 Mya. Contrary to previous studies that identified only a few shared biomineralization transcripts across the Bivalvia, …

Ecosystem Metabolism In Small Ponds: The Effects Of Floating-Leaved Macrophytes, Daniel J. Hornbach, Emily G. Schilling, Holly Kundel

Faculty Authored Articles

Small ponds constitute a significant number of standing water bodies on earth and may contribute to CO2 uptake or release into the atmosphere. Despite their importance, few studies have examined ecosystem metabolism in ponds, especially in ponds that may be dominated by floating-leaved macrophytes. In this study, we examined ecosystem metabolism by measuring changes in dissolved oxygen levels every 10 min from late May through late October for four shallow ponds (0.5–1.5 m) in east-central Minnesota, USA. Ponds had varying levels of floating-leaved macrophytes from sparse (<1% coverage) to abundant (61% coverage). We found significant dierences in a number of physical/chemical factors including P, N, DOC, water temperature and light penetration. We also found significant dierence in gross primary production (GPP—average ranged from 2.2 to 5.5 mg O2/L/day), respiration (R—average ranged from 􀀀6.8 to 􀀀3.6 mg O2/L/day) and net ecosystem production (NEP—average ranged from 􀀀1.5 to 􀀀0.1 mg O2/L/day) among the ponds. On average, all of the ponds were heterotrophic (R > GPP). While it appeared that floating-leaved macrophytes provided a significant impact on ecosystem …

Status Of The Blackstripe (Fundulus Notatus) And Blackspotted (F. Olivaceus) Topminnows In The Ozark Uplands Of Central Missouri, Nathaniel Steffensmeier, Naznin Sultana Remex, Robert Hrabik, David D. Duvernell

Southeastern Fishes Council Proceedings

The topminnow species Fundulus notatus and F. olivaceus have broadly overlapping geographic distributions that extend throughout much of the central and southern United States. In the northern portion of their respective ranges, in Missouri, the regional distributions of the two species coincide largely with recognized ecoregions. In the unglaciated southern half of Missouri, F. olivaceus is distributed throughout Ozark upland habitats while F. notatus is abundant in marginal large river and prairie habitats along the Ozark borders. An exception to this partitioning is the historical report of abundant F. notatus in the Bourbeuse and upper Meramec River drainages within the …

Use Of Dead Mussel Shells By Madtom Catfishes In The Green River, Jacob F. Brumley, Philip W. Lienesch

Southeastern Fishes Council Proceedings

The Green River in Kentucky has high fish and macroinvertebrate diversity. As both fish and macroinvertebrates have evolved together in this system, relationships have developed between species. One type of relationship that has been observed is between madtom catfishes (Noturus spp.) and mussels in the Green River, where madtoms use dead mussel shells as cover when not actively foraging. In the fall of 2016 and 2017, surveys were conducted to determine if madtom catfishes use dead mussel shells more than rocks of similar size. We predicted that madtoms would select mussel shells as cover more frequently than rocks due …

Species Dispersal Modes In Amphitropical Plant Species Of North And South America, Samera Lemma Mulatu

Honors College Theses

Amphitropical disjunct plants are species that occur in both North and South America but not in the intermediate equatorial region. How amphitropical species dispersed across the Americas to their current distribution remains uncertain. To explain amphitropical distributions, three hypotheses were developed to test that (1) species dispersed successively through island hopping across the tropical zone in temperate microhabitats (= stepping stones), (2) species came to their current distribution through vicariance, or (3) species dispersed by a single long distance dispersal event. Twenty-five species were studied to infer their historical distributions with species distribution models in MaxEnt. Distribution models for each …

Anchialine Biodiversity In The Turks And Caicos Islands: New Discoveries And Current Faunal Composition, Brett C. Gonzalez, Alejandro Martínez, Jørgen Olesen, Sarit B. Truskey, Lauren Ballou, Marc Allentoft-Larsen, Joost Daniels, Paul Heinerth, Mark Parrish, Naqqi Manco, Jon Ward, Thomas M. Iliffe, Karen J. Osborn, Katrine Worsaae

International Journal of Speleology

Lying at the southernmost point of the Lucayan Archipelago, the Turks and Caicos Islands are amongst the better studied localities for anchialine cave biodiversity. For nearly five decades, novel invertebrate fauna, comprised primarily of crustaceans, have been collected from these tidally influenced pools – but new findings are always on the horizon. Herein we present new records of crustaceans and annelids from anchialine blue holes and horizontal caves of the Turks and Caicos. These findings include two potentially new species of meiofaunal annelids and a new species of remipede collected from a shallow water cave pool. Our 2019 expedition additionally …

Assessing Methods For Determining Reference Conditions For Riparian Restoration In Santa Clara County, Claire Mallen

Master's Theses

Valley Water is the primary water wholesaler and flood control agency in Santa Clara County, providing services to 1.9 million residents. The operation and maintenance of infrastructure for water supply and flood control often require work within legally protected natural resources such as riparian ecosystems. Riparian ecosystems are dynamic and diverse ecosystems that provide our society with valuable services such as wildlife habitat, water quality, and recreation. However, the threat of human development on native ecosystems has led to the degradation and loss of 85-98% of riparian ecosystems nationwide. Today, federal, state, and regional laws mitigate further impacts to riparian …
