Тaxonomic Position Of Orthochirus Olivaceus (Karsch, 1881), The Type Species Of The Genus Orthochirus Karsch, 1892 (Scorpiones: Buthidae), František Kovařík, Victor Fet, Manal Siyam
Euscorpius
We address the taxonomic position of Orthodactylus olivaceus Karsch, 1881, the type species of the genus Orthochirus Karsch, 1892. For over a century, this taxon was considered a synonym of Orthochirus scrobiculosus (Grube, 1873); however, the latter was recently limited to Central Asia (Turkmenistan) (Kovařík et al., 2020). Analysis of Karsch’s holotype confirmed that Orthochirus olivaceus (Karsch, 1881), is a valid species. Its type locality published as “Sicily” is clearly incorrect. It is a senior synonym of Butheolus aristidis Simon, 1882, syn. n., described from Sudan (Nubia). We confirm its distribution in northern Sudan and southern Egypt.
The Role Of Microhabitats In Structuring Cave Invertebrate Communities In Guatemala, Gabrielle S.M. Pacheco, Marconi Souza Silva, Enio Cano, Rodrigo L. Ferreira
The Role Of Microhabitats In Structuring Cave Invertebrate Communities In Guatemala, Gabrielle S.M. Pacheco, Marconi Souza Silva, Enio Cano, Rodrigo L. Ferreira
International Journal of Speleology
Several studies have tried to elucidate the main environmental features driving invertebrate community structure in cave environments. They found that many factors influence the community structure, but rarely focused on how substrate types and heterogeneity might shape these communities. Therefore, the objective of this study was to assess which substrate features and whether or not substrate heterogeneity determines the invertebrate community structure (species richness and composition) in a set of limestone caves in Guatemala. We hypothesized that the troglobitic fauna responds differently to habitat structure regarding species richness and composition than non-troglobitic fauna because they are more specialized to live …

Groundwater Quality In Two Semi-Arid Areas Of Algeria: Impact Of Water Pollution On Biodiversity, Redjaimia Lylia, Hadjab Ramzi, Khammar Hichem, Merzoug Djemoi, Saheb Menouar
Journal of Bioresource Management
The biodiversity and quality of subterranean waters were comparatively studied in the Tarf plain near Oum-El-Bouaghi and in the Ksar S’bahi in Oum-El-Bouaghi, in North-eastern Algeria. For this purpose, physicochemical and faunistic analyses were carried out on the water of ten stations located in the area of Tarf, and thirteen in the area of S’bahi. In the wells of Tarf, the average stygobiologic diversity was relatively high in the wells located upstream the dumping site from the city where the groundwater presented low contents of nitrates and orthophosphates. In contrast, the wells located in the spreading zone of Tarf wastewaters …

True morels collected from wild provide an economic source for the rural community of Mankial valley (District Swat, Khyber Pukhtunkhawa, Pakistan). Sale of approximately 334 kg in dry weight of five species of true morels (Morchella conica, M. esculenta, M. deliciosa, M. rotunda and M. semilibera) fetch US$ 57133 (under US$ 2015-16 exchange rate) to Mankial community and generate a revenue of US$ 62935 in Mingora (regional market) and US$ 87011 in Islamabad (national capital) markets. Morchella conica (average annual dry weight harvested 156 kg) has a high market price value (US$ 2964-44616) in all the three markets. …
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
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 …

We demonstrate for the first time that the name …
Description Of The Male Of Wernerius Mumai (Sissom, 1993) From Western Arizona, With Data On Reproduction (Scorpiones: Vaejovidae), Richard F. Ayrey, Brandon T. Myers
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
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
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
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 …
The Effects Of Elevation On Foraging Behavior Of Bats In Southern Appalachia, Victoria Long
The Effects Of Elevation On Foraging Behavior Of Bats In Southern Appalachia, Victoria Long
Electronic Theses and Dissertations
There are limited studies on bat activity in higher elevations in the Appalachian region. Levels of bat activity were compared in south central Appalachia at low (< 914.4 m) and high (> 1, 524 m) elevations in open, forest edge, and riparian habitats. Additionally, habitat suitability was modeled for a common species, big brown bat (Eptesicus fuscus). The study started May 27th 2019, and sites were monitored biweekly until October 2nd 2019. Six species and one genus were recorded during the study. Species from the Myotis genus were grouped together because of similar call characteristics. Results show that species were significantly more …

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 …

Population Status, Threats, And Conservation Of Preuss's Red Colobus (Piliocolobus Preussi) And Other Diurnal Primates In The Ndokbou Forest, Littoral Region, Cameroon, Ruth Bowers-Sword
Masters Theses, 2020-current
The Ebo-Makombe-Ndokbou forest block in southwest Cameroon lies within the Gulf of Guinea biodiversity hotspot, characterized by extremely high levels of species richness and endemism, including those of primates. These forests may contain one of the last populations of the Critically Endangered Preuss’s red colobus monkey (Piliocolobus preussi; PRC), which is found only in southeastern Nigeria and western Cameroon. Gun hunting for bushmeat and habitat loss and degradation from logging and agriculture are the main threats to PRC. The conservation status of PRC and other primates in the Ndokbou forest are largely unknown, with most regional research efforts occurring in …
Evaluating The Effect Of The Removal Of Non-Native Trout In Two High Elevation Tributary Streams In The Intermountain West, Clint Brunson
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 …
Interrelationships Among Monorchiid Trematodes With Special Emphasis On Some Northwestern Atlantic Genera, Apryle Panyi
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 …

Five New Species Of Euscorpius Thorell, 1876 (Scorpiones: Euscorpiidae) From Albania, Greece, North Macedonia, And Serbia, František Kovařík, František Šťáhlavský
Euscorpius
Five new species are described: Euscorpius bonacinai sp. n. (Albania), E. janstai sp. n. (North Macedonia), E. kabateki sp. n. (Greece), E. sadileki sp. n. (Serbia), and E. scheraboni sp. n. (Greece), fully complemented with color photographs. New species are distinguished from all other species of the genus on the basis of five taxonomic characters. Two other new characters, shape of the pedipalp chela fingers and number of chromosomes, are presented and discussed. In addition to the analyses of external morphology, we also describe karyotypes of two species: E. janstai sp. n. (2n=112) and E. sadileki sp. n. (2n=90).
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
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 …

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 …

Floodplain Forest Regeneration Dynamics In The Lower Mississippi River Alluvial Valley, Whitney Anne Kroschel
Floodplain Forest Regeneration Dynamics In The Lower Mississippi River Alluvial Valley, Whitney Anne Kroschel
LSU Doctoral Dissertations
Floodplain forest species diversity is driven, in part, by variation in disturbance regime. Flood patterns create heterogeneity in microsite quality from small differences in elevation across a floodplain which, in turn, influence flood timing and duration. Differences in species’ regeneration niches in relation to hydrologic patterns can account for long-term coexistence of various species. In the past century floodplain forests have exhibited a wide range of changes in stand development and species composition as a result of altered hydrology in rivers and floodplains. I evaluated the role of regeneration in floodplain forest systems of the Lower Mississippi River Alluvial Valley …
Vertebrates On The Brink As Indicators Of Biological Annihilation And The Sixth Mass Extinction, Gerardo Ceballos, Paul R. Ehrlich, Peter H. Raven
Vertebrates On The Brink As Indicators Of Biological Annihilation And The Sixth Mass Extinction, Gerardo Ceballos, Paul R. Ehrlich, Peter H. Raven
Harold W. Manter Laboratory of Parasitology: Library Materials
The ongoing sixth mass species extinction is the result of the destruction of component populations leading to eventual extirpation of entire species. Populations and species extinctions have severe implications for society through the degradation of ecosystem services. Here we assess the extinction crisis from a different perspective. We examine 29,400 species of terrestrial vertebrates, and determine which are on the brink of extinction because they have fewer than 1,000 individuals. There are 515 species on the brink (1.7% of the evaluated vertebrates). Around 94% of the populations of 77 mammal and bird species on the brink have been lost in …

Migration ecology and habitat use of spring migrating birds using the Central Platte River is a well-explored topic, yet less is known about use of the North and South Platte rivers (NSPR) in western Nebraska. The efficiency and effectiveness of conservation efforts in the NSPR could be greatly improved with access to information about where and when birds roost and landscape prioritization tools. We used aerial surveys to determine population distribution and migration phenology of sandhill cranes Antigone canadensis, Canada geese Branta canadensis, and ducks using the NSPR for roosting during the mid-February to mid-April spring migration. We used these …
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
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 …

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 …
