Crassostrea Gigas Invasion In Southern California: Macrofaunal Diversity And Local Community Impacts Of Ecosystem Engineers On Estuarine Habitats, Noah Jansen-Yee 2022 University of San Diego

Crassostrea Gigas Invasion In Southern California: Macrofaunal Diversity And Local Community Impacts Of Ecosystem Engineers On Estuarine Habitats, Noah Jansen-Yee

Theses

Many marine ecosystems are facing the growing threat of biological invasions. These invasions can have a variety of different impacts on ecosystems and their inhabitants. The Pacific oyster, Crassostrea gigas, is currently in the relatively early stages of invasion in San Diego estuaries. Crassostrea gigas is a large, filter-feeding bivalve that forms dense oyster beds on hard substrate. These oysters are known to outcompete native counterparts and drastically alter habitats where they are present. Crassostrea gigas is an ecosystem engineer that, through shell creation and formation of a dense oyster matrix, impacts ecosystems in a variety of direct and indirect ...


Observations On Regeneration Of The Pedipalp And Legs Of Scorpions, Martin Watz, Jason A. Dunlop 2022 Marshall University

Observations On Regeneration Of The Pedipalp And Legs Of Scorpions, Martin Watz, Jason A. Dunlop

Euscorpius

An Opisthacanthus asper (Peters, 1861) (Hormuridae) shows a relatively rare example of pedipalp regeneration in which the lost tibia and tarsus was replaced by a smaller, curved element of uncertain homology to either the fixed or free finger. A comparable abnormal palp described in the literature hints that pedipalps can only regenerate a structure of this form, regardless of the site of amputation. An Olivierus caucasicus (Nordmann, 1840) (Buthidae) is described in which claws (pretarsus) of leg III regenerated directly at the distal end of the tibia, while in leg IV the claws regenerated at the end of a truncated ...

Artificial Intelligence System For Automatic Imaging, Quantification, And Identification Of Arthropods In Leaf Litter And Pitfall Samples, Pierce Helton, Khoa Luu, Ashley Dowling 2022 University of Arkansas, Fayetteville

Artificial Intelligence System For Automatic Imaging, Quantification, And Identification Of Arthropods In Leaf Litter And Pitfall Samples, Pierce Helton, Khoa Luu, Ashley Dowling

Inquiry: The University of Arkansas Undergraduate Research Journal

It is well known that arthropods are the most diverse and abundant eukaryotic organisms on the planet. Museum and research collections have huge insect accumulations from expeditions conducted over history that contain specimens of both temporal and spatial value, including hundreds of thousands of species. This biodiversity data is inaccessible to the research community, resulting in a vast amount of “dark data”. The primary objective of this study is to develop an artificial intelligence-driven system for specimen identification that greatly minimizes the time and expertise required to identify specimens in atypical environments. Successful development will have profound impacts on both ...


Differentiating The Effects Of Two Non-Native Fish In The Turnbull National Wildlife Refuge, Sarah Richardson 2022 Eastern Washington University

Differentiating The Effects Of Two Non-Native Fish In The Turnbull National Wildlife Refuge, Sarah Richardson

EWU Masters Thesis Collection

This study seeks to determine the individual effects of two non-native fish, the brook stickleback, Culaea inconstans, and pumpkinseed, Lepomis gibbosus, on the aquatic invertebrates and food webs of Turnbull National Wildlife Refuge (TNWR). Ten ponds were analyzed and compared with stable isotope analysis and invertebrate abundance data. Three ponds were chosen to represent each of the following categories: fishless, brook stickleback invaded (BS), and coinvaded, along with a single pumpkinseed (PS) pond. Overall, δ[superscript]13C and δ[superscript]15N values increased in invaded ponds, indicating shifts in the zooplankton community structure and the carbon source of predatory invertebrates ...


Understanding Caribou Population Cycles, Jack R. St. John 2022 University of Montana

Understanding Caribou Population Cycles, Jack R. St. John

Undergraduate Theses, Professional Papers, and Capstone Artifacts

The complex population dynamics of caribou (Rangifer tarandus) were studied to determine the patterns of their population cycles and the processes driving them. It is well established, via previous archaeological research and Indigenous knowledge, that large migrating caribou herds found in and around the tundra at northern latitudes experience population boom and busts roughly every several decades. However, the processes driving the dynamics of these cycles are relatively unknown, which makes managing caribou herds for recreational and subsistence harvests difficult. It has been hypothesized that a combination of intrinsic and extrinsic factors shape these cycles, with density-dependence, predation, harvest, climate ...


Raven Control From A Conservation Biology Perspective, David J. Delehanty 2022 Idaho State University, Department of Biological Sciences, Pocatello, ID 83209

Raven Control From A Conservation Biology Perspective, David J. Delehanty

Human–Wildlife Interactions

The common raven (Corvus corax; raven) is a large, highly intelligent passerine songbird with a Holarctic distribution attributable to a high degree of plasticity in its foraging and nesting behavior. Historically, ravens have received special attention in human culture, being either respected or vilified. In the western United States, ravens are exploiting the expanding human enterprise, which provides them with unintended subsidies of food, water, and breeding locations, allowing ravens to expand their range and increase in population density and resulting in raven depredation threatening species of conservation concern. From a conservation biology perspective, increased raven populations present a difficult ...


An Assessment Of Geographic And Taxonomic Biases In Research On Climate Change-Related Range Shifts, Evan J. Parker 2022 Yale University

An Assessment Of Geographic And Taxonomic Biases In Research On Climate Change-Related Range Shifts, Evan J. Parker

Library Map Prize

Geographic and taxonomic biases in ecological literature inhibit the ability of research to be generalized or translated to other systems. This is particularly true with research on climate change-related range shifts, where a diverse and representative set of observations is needed to understand the significant heterogeneity of range shifts and improve models. A literature review was conducted and biases were assessed by examining the geographic location of study areas, the taxonomic makeup of study species, and the location of study areas within species ranges. A substantial geographic skew towards terrestrial, mid-latitude North America and Europe was observed. However, taxonomic coverage ...

Biological Sciences Faculty Publications

Global biodiversitytargets require us to identify species at risk of extinction and quantify status and trends of biodiversity. The Red List Index (RLI) tracks trends in the conservation status of entire species groups over time by monitoring changes in categories assigned to species. Here, we calculate this index for the world’s fishes in 2010, using a sampled approach to the RLI based on a randomly selected sample of 1,500 species, and also present RLI splits for freshwater and marine systems separately. We further compare specific traits of a worldwide fish list to our sample to assess its representativeness ...


Increasing Detection Sensitivity For Rare And Endangered Species In Kansas Through Development Of An Aquatic Environmental Dna Sampling Protocol, Sarah Hallyburton 2022 Fort Hays State University

Increasing Detection Sensitivity For Rare And Endangered Species In Kansas Through Development Of An Aquatic Environmental Dna Sampling Protocol, Sarah Hallyburton

Master's Theses

Anthropogenic global climate change is forcing the mass extinction of wildlife across the globe. Humans depend on freshwater ecosystems for many aspects of life including agricultural production, sanitation, and recreation. Healthy levels of biodiversity in freshwater environments ensure economically beneficial ecosystem services are maintained. Freshwater ecosystems are hotspots for biodiversity and have higher levels of imperiled organisms compared to terrestrial and marine systems. Within freshwater systems, freshwater mussels (Family: Unionidae) are the most imperiled with over 70% of North American species assigned to a conservation class as judged by state or federal management agencies. The objective of this study was ...

Journal of Bioresource Management

The cedar forests in Algeria represent a model of forests very rich in entomological fauna and especially dictyopterans, notably blattopterans. In the cedar forest of Chelia in the Aurès Mountains, we chose three different sites according to altitude (2020 m, 1920 m, 1820 m) in order to collect existing cockroaches using the sight-hunting method (twice a month). The inventory allowed us to capture more than 1220 cockroaches and we were able to identify three genus (Dziriblatta, Phyllodromica ,Loboptera) and seven species: Dziriblatta stenoptera, Dziriblatta nigrivintris, Phyllodromica zebra, Pyllodromica trivittata, Phyllodromica sp, Loboptera angulata, Loboptera alluaudi, of which Dziriblatta nigrivintris is ...

An Assessment Of The Diverse Freshwater Turtle Fauna Of Mississippi, Lucas Haralson 2021 The University of Southern Mississippi

An Assessment Of The Diverse Freshwater Turtle Fauna Of Mississippi, Lucas Haralson

Master's Theses

Nestled within the Southeastern United States Turtle Priority Area, Mississippi boasts impressive freshwater turtle diversity and is home to 8.6% of extant turtle species. Despite this impressive richness, few studies have assessed freshwater turtle assemblages in this hotspot of aquatic diversity. This research aimed to elucidate the distributions and abundances of freshwater turtle species through a statewide investigation of all major river drainages of the state. Using baited hoop nets (90 cm and 120 cm diameter), turtles were collected, identified to species and sex, and measured, before being released. Turtle assemblages were assessed in both lotic and lentic environments ...
