Concepts In Animal Parasitology, Chapter 69: A Short Introduction To Marine Parasitology: Marine Parasites Of Economic And Medical Importance [Auxiliary Concepts], Klaus Rohde, Robin M. Overstreet

Concepts in Animal Parasitology

Chapter 69 in Concepts in Animal Parasitology, S. L. Gardner and S. A. Gardner, editors. 2024. Zea Books, Lincoln, Nebraska, United States

Introduction

Parasitism, in this chapter, is defined as “a close association of two organisms, in which one—the parasite—depends on the other—the host—deriving some benefit from it. The benefit is often food” (Rohde, 2005b). Many bacteria, viruses, and fungi are parasitic but usually not studied by parasitologists sensu stricto; they are the domain of microbiologists. Parasites as defined here do not always harm their host; the border between so-called genuine parasites and other symbionts such as commensals is often …

Human–Wildlife Interactions

Feeding management can be a good strategy for avoiding wildlife–vehicle collisions (WVCs), which are a worldwide concern. In this study, we aimed to identify grass species that capybaras (Hydrochoerus hydrochaeris) reject as feeding material. These species could be planted to make roadsides less attractive to capybaras and, consequently, decrease WVCs involving this species. We planted 3 grass species (Brachiaria decumbens cv. Basilisk, B. hybrid Mavuno, and Zoysia japonica) in 4 blocks, applying a randomized-complete blocks design. The first 2 species we assumed would be rejected, since some animals do not consume them due to their high …


Grazing Management For Livestock, Free-Roaming Horses And Burros, And Resilience, Sherman R. Swanson Jan 2024

Grazing Management For Livestock, Free-Roaming Horses And Burros, And Resilience, Sherman R. Swanson

Human–Wildlife Interactions

Grazing management avoids overgrazing by allocating forage for livestock on the basis of animal unit months and managing wild and free-roaming horses (Equus caballus) and burros (E. asinus) to achieve and maintain an appropriate management level (AML) for each herd. Riparian green forage and water attracts cattle (Bos taurus) and equids when upland forage is brown. Key species that focus management for resilience to weather variation, fire, and floods are preferred forage plants for cattle and horses. They include riparian stabilizers such as densely rooted sedges and deep-rooted perennial grasses in sagebrush (Artemisia …

Survival Of Translocated Coyotes In The Chicago Metropolitan Area, Usa, Charlotte R. Milling, Chris Anchor, Stanley D. Gehrt Jan 2024

Survival Of Translocated Coyotes In The Chicago Metropolitan Area, Usa, Charlotte R. Milling, Chris Anchor, Stanley D. Gehrt

Human–Wildlife Interactions

For nuisance animals, the general public perceives translocation to be a humane alternative to lethal control measures, but survival of translocated wildlife is often quite low due in part to increased movement post-release. Thus, for common species whose relocation generally serves a social rather than conservation purpose, translocation might not be correctly characterized when presented as nonlethal. We quantified release site fidelity and survival of coyotes (Canis latrans) fitted with very high frequency radio-collars and translocated within the Chicago Metropolitan Area, Illinois, USA, from 2000 to 2006. We also compared survival for 14 weeks post-collaring for our translocated …

Impact Of Road Infrastructures On The Abundance Of Common Chameleon Populations, Pablo García-Quevedo, Francisco Díaz-Ruiz, Antonio Román Muñoz, Jesús Duarte, Adrián Martín-Taboada, José-María García-Carrasco, Miguel Ángel Farfán Jan 2024

Impact Of Road Infrastructures On The Abundance Of Common Chameleon Populations, Pablo García-Quevedo, Francisco Díaz-Ruiz, Antonio Román Muñoz, Jesús Duarte, Adrián Martín-Taboada, José-María García-Carrasco, Miguel Ángel Farfán

Human–Wildlife Interactions

The common chameleon (Chamaeleo chamaeleon) is a threatened species in Spain. The loss and transformation of their traditional habitats are among the main causes of its decline. Linear infrastructures, such as roads and highways, cause direct habitat loss, roadkill, and fragmentation of populations by acting as an artificial barrier. In this study, we investigated the potential effect of 2 high-speed road infrastructures in southern Spain on local populations of common chameleons. A total of 34 grids of 1x1 km were sampled, differentiating between grids without road presence (n = 17) and grids with road presence (n …


Dust Management At An Active Construction Area Affects Monarch Distribution, Amy W. O'Donnell, Jeffery D. Sullivan, Carl R. Callahan, Peter C. Mcgowan, Diann J. Prosser Jan 2024

Dust Management At An Active Construction Area Affects Monarch Distribution, Amy W. O'Donnell, Jeffery D. Sullivan, Carl R. Callahan, Peter C. Mcgowan, Diann J. Prosser

Human–Wildlife Interactions

The North American population of monarch butterflies (Danaus plexippus) is experiencing dramatic declines, necessitating investigations into challenges facing this species that can be resolved through management actions. For instance, dust made airborne by heavy equipment driving along a dirt road can settle on roadside vegetation, resulting in reduced use by monarchs. Dust accumulation on areas where floral nectaries such as leaves, stems, and flowers may be present could reduce the ability of pollinators, such as monarchs, to access nectar from flowering plants needed during migration. One such challenge was observed on Poplar Island, an island restoration project located in …

The complex microbial ecosystem within sewage systems holds significant implications for environmental and public health. Unlike studies on wastewater treatment plant microbiomes, upstream sewage systems have not been studied widely. This research investigated the dynamic sewage microbiome across diverse serving neighborhoods in Charleston, Illinois, encompassing residential, hospital, industrial, and university areas. Drawing upon recent advancements in microbiome research, the study aimed to unravel the spatial and temporal variations in microbial structures. Three times between June to December 2023 sewage samples were collected from manholes in the areas mentioned above. Community DNA was extracted and sequenced for the V4-V5 region of …


Leaf To Canopy Functional Resilience: Plant Physiological And Carbon Cycling Stability Following Disturbances, Lisa T. Haber Jan 2024

Leaf To Canopy Functional Resilience: Plant Physiological And Carbon Cycling Stability Following Disturbances, Lisa T. Haber

Theses and Dissertations

Ecological disturbances impact core ecosystem functions, including production and biogeochemical cycling, by precipitating changes in biodiversity, physical environmental variables, vegetation structure, and functional trait distributions. As disturbance patterns intensify and abruptly transition to novel regimes under global change, future trajectories of ecosystem functions, including carbon (C) uptake and storage, are uncertain. A more complete understanding of the mechanisms underpinning ecosystem stability (or ability to return to baseline functioning) following disturbance is needed to forecast future C cycling.

Replicated ecosystem-scale disturbance experiments, particularly when coupled with modeling, are required to rigorously test hypothesized trajectories of ecosystem structural and functional change following …


Hunting Types In North American Eocene And Oligocene Carnivores And Implications For Nimravid Extinction, Miguel Andres Castellanos Jan 2024

Hunting Types In North American Eocene And Oligocene Carnivores And Implications For Nimravid Extinction, Miguel Andres Castellanos

Graduate Research Theses & Dissertations

The late Eocene and Oligocene is traditionally seen as a time of great climactic shift, with open habitats beginning to appear and forests receding. This time period saw both the diversification and subsequent extinction of North American nimravids. The causes of the extinction of this early sabertooth group in the Arikareean remain unclear. One possibility for their decline is that nimravids were competitively disadvantaged in open habitats relative to contemporary, possibly more cursorial caniform predators. Here I analyze and compare the hunting styles of Eocene and Oligocene predators in correlation with their ecological implications via discriminant function analysis of the …

The Energetics Of Seasonality In Wild Diademed Sifaka (Propithecus Diadema): A Technical And Biological Validation Of Fecal Triiodothyronine Radioimmunassay, Casey Farmer

Graduate Research Theses & Dissertations

The energetic state of an animal has vital consequences for its fitness, but it can be difficult to detect through behavioral observations. The development of techniques to determine an animals’ energetic state non-invasively would allow conservation planners to rapidly assess the energy balance and conservation potential of individuals, groups, and populations. Thyroid hormones like triiodothyronine (T3) regulate and reflect metabolic state in mammals. T3 is a non-invasive biomarker that can be detected in feces and could potentially be used for this purpose. I perform the first validation of a commercially available T3 radioimmunoassay designed for humans on a wild strepsirrhine …
