Preventing the Catch and Release of Teachers In South Carolina: A Look Into the Induction Program Components That Influence Induction Teacher Retention
<p>Catch and release is a practice within recreational fishing intended as a technique of conservation. After capture, the fish are unhooked and returned to the water before experiencing serious exhaustion or injury. This prevents a shortage in the supply and sustains a supply of fish. However, in …

Biological Impacts and Uses of Black Bass Competitive Fishing Tournaments on Large Lake Systems
… North America are valued between $47.3 billion and $56.8 billion. Fisheries managers must make strategic decisions based on sound science and knowledge of population ecology, to effectively conserve populations. Competitive fishing, in the form of tournaments, has become an important part of …

Evaluating the effects of angler behavior on the efficacy of harvest regulations in recreational fisheries
… modified to compare various regulation schemes and determine how they are affected by angler non-compliance and voluntary catch-and release fishing. Combinations of three creel limits and five length limits were simulated. Scenarios for no regulations and catch-and-release were also simulated. …

Ecological and recreational interactions of the native pike Esox lucius and the invasive pikeperch Sander lucioperca in England.
In England, freshwater angling is an important recreational pastime with substantial socio-economic benefits, but is also a major introduction pathway for non-native fishes. As recreational anglers often prefer targeting large-bodied fishes, introductions of non- native species have become an …

Do Angler Handling Practices Influence the Short-Term Post-Release Behaviour of Black Bass?
… benefits to local communities. Anglers often release Black bass due to seasonal regulations, tournament regulations or because of personal conservation ethic, with the expectation that released fish will survive the angling interaction. Biologgers were used to analyse the short-term …

Conjugation of oligonucleotides for drug delivery via a linker derived from Meldrum’s acid and A capture-release method to synthesize long oligonucleotides
… facilitating the stepwise attachment of an amine and a thiol under mild and neutral aqueous conditions. This methodology uniquely enables the subsequent decoupling reaction with a specific chemical trigger. A novel aspect of this research is the substitution of dithiothreitol which is not …

Characterizing a Hidden Fishery: Setline Fishing in the New River, Virginia
… New River, Virginia by multiple methods, yet standard creel survey approaches do not accurately sample setline effort, a popular fishing gear for catfish. I characterized the New River setline fishery by estimating setline effort and catch rates of catfish and by-catch in 2011, and by …

Recreational specialization as an indicator of attitudes and management preferences of Virginia river anglers
… fisheries managers must identify the subgroups and their corresponding attributes to guide management programs. This study was designed to evaluate the concept of recreational specialization for differentiating angler subgroups, and to determine if angler attitudes and management preferences …

Modelling to compare harvest regulations in recreational fisheries: case study of smallmouth bass fisheries
… of complete trip creel survey data from the New and Shenandoah Rivers in Virginia and West Virginia. The fits for eight of ten datasets were not significantly different from the observed distributions (P< 0.05). The negative binomial provides a good alternative when complete trip data are …

Biologging for marine megafauna conservation: animal tracking, environmental monitoring, and modelling approaches.
… including fishing pressure, habitat destruction, and climate change. Biologging—the use of electronic tags to study animal movement, behaviour, physiology—has emerged as a critical tool for understanding animal ecology and informing conservation strategies. This thesis explores the application of …

A small molecule synthesizer
… remains a relatively complex, unsystematized, and time-intensive process practiced almost exclusively by highly trained specialists. Collectively, these limitations represent a major bottleneck in the efforts to study, understand, and harness the vast functional capacity of small molecules. In …

New Purification Strategies and Monomer Platforms for Ruthenium-Initiated Living Ring-Opening Metathesis Polymerization
… 1: Introduction to Covalent Capture Purification and Ring-Opening Metathesis Polymerization In chemical spaces where difficult purifications are commonplace, innovative purification methodologies have been developed to circumvent the limitations associated with classical physiochemical …

Local and Regional Aspects of Habitat Quality Jointly Affect the Biodiversity of Ephemeral Ponds
… is likely affected by both local habitat quality and by the quality of the landscape surrounding the locality. In pond environments, habitat quality may be affected by the kind of leaf litter present because leaf species differ in the kind of habitat structure they provide and the rate at which …

Stereoselective synthesis and iterative coupling of Csp3 boronates for automating small molecule synthesis
… many important functions in nature, medicine, and technology. However, efforts to discover and optimize new small molecule function are often impeded by limitations in synthetic access to this class of compounds. In contrast to peptide and oligonucleotide syntheses, small molecule syntheses …

Impacts of population-level reproductive success on recruitment dynamics in largemouth bass (Micropterus salmoides)
Understanding the mechanisms that govern recruitment in fish populations is fundamental to informing management decisions that are designed to provide sustainable recreational fisheries. The Largemouth Bass (Micropterus salmoides) is a popular and widely exploited sport fish that provides …

An Inferentially Robust Look at Two Competing Explanations for the Surge in Unauthorized Migration From Central America
… immigrant advocates, progressive media outlets, and human rights organizations identify poverty and violence (the Poverty and Violence Hypothesis) in Central America as the primary triggers responsible. In contrast, while most government officials, conservative think tanks, and the agencies that …
