Three Essays on the influence of company Facebook and traditional channel activities on recruitment success
… components have extended the spectrum of recruitment channels. The new recruitment media channels have led the selection and analysis of their impact out of interaction on each other to a new challenge within academical literature. This dissertation addresses these issues in three separate …

Carry-Over Effects in Complex Life Cycles: Linking Larval Food Supply with Juvenile Recruitment Success in Sea Stars
The supply of new individuals into a population is one of the most important factors impacting species distributions and ecological interactions within a community. For marine invertebrates with complex life cycles, the supply of new individuals into a population can be influenced by factors …

High School Forensics Services and Recruitment: a Study of High School Faculty Opinion
… to debate. Although forensics services and recruitment are expanding at the University, no research has been done to evaluate their effectiveness. This thesis attempts to evaluate Southwest Missouri State University forensics services and offers recommendations for future study. A …

Genetic Dissection of Anthropogenic Impacts on a Declining Antarctic Fur Seal Population
… individuals is increasing and occurs before recruitment. This leaves two, non-exclusive possibilities: selection acts during the pup life-history stage or the juvenile life-history stage. Studies of other pinnipeds have shown that the highest mortality occurs in the juvenile life-history …

Applications of fish scale analysis to understand growth dynamics of fish populations
… to examine the differences between regional recruitment success, and found similarities and differences at both the regional and national level. With recruitment success a key requirement of monitoring fish populations under the WFD, it is hoped the information provided here will aid …

Evaluating the effects of rainbow smelt on native piscivores in freshwater systems with a special focus on walleye recruitment and larval bioenergetics
… piscivores and adult rainbow smelt can limit recruitment success of piscivores. In other cases, rainbow smelt have no such impacts on piscivores and only serve as a forage fish. In a literature review, I exploredrainbow smeltinteractions withthree different piscivore species, Atlantic salmon …

Episodic Recruitment and Climate Analysis of Ponderosa Pine on the Palmer Divide, Eastern Colorado
<p>Previous recruitment studies on populations of ponderosa pine (<em>Pinus ponderosa</em> P. & C. Lawson) in Colorado have been limited to the western mountains and the Front Range. In this research I used tree-ring data to reconstruct recruitment for ponderosa pine near the eastern limits of its …

Spatial Distribution and Stock-Recruitment Analysis of the Atlantic Surfclam, <i>Spisula solidissima</i>, in the Mid-Atlantic Bight and on Georges Bank
… independent statistical analyses of the stock-recruitment relationship found little evidence of a significant association in any of the 5 regions, suggesting that factors besides spawning stock biomass are primary determinants of recruitment success. The recruitment index obtained from the …

Recruitment to randomised controlled trials with children
Recruitment to randomised controlled trials is known to be difficult. Poor recruitment has several adverse consequences. It affects the validity of study findings, is a common cause of trial extensions and may result in premature termination of trials, which is a huge loss in terms of invested …

Modeling the processes affecting larval haddock (Melanogrammus aeglefinus) survival on Georges Bank
… the past century has been to better understand recruitment variability. Recruitment is the single most important natural event controlling year-class strength and biomass in fish populations. As evident in Georges Bank haddock, Melanogrammus aeglefinus, there is a strong relationship between …

Bet- hedging reproduction strategies in the massive Caribbean coral Favia fragum
… cues that have previously secured reproductive success in tropical scleractinian corals and enabled them to fine-tune their reproductive patterns to time periods that optimize external fertilization success, appropriate larval dispersal and efficient coral recruitment. This study tested the …

Larval ecology and synchronous reproduction of two crustacean species : Semibalanus balanoides in New England, USA and Gecarcinus quadratus in Veraguas, Panama
… potential sources of larval mortality and recruitment success. High-frequency observations revealed that early-stage larval abundance of S. balanoides was related to storms, and possibly turbidity. Field observations and experiments studied the effect of turbidity and phytoplankton on …

Spatial and Temporal Variation in Growth Rate of Blue Rockfish (Sebastes mystinus) in Nearshore Central California Determined Using a Physiological Biomarker
… as somatic growth rate, which can be central to recruitment success and survival. In this study, we employed a novel physiological approach using the hormone insulin-like growth factor-1 (Igf-1) as a blood-based ‘biomarker’ for recent growth rate to determine patterns of spatial and temporal …

Ecology of the Early Life History of the Caribbean Spiny Lobster, <i>Panulirus argus:</i> Recruitment, Predation, and Habitat Requirements
<p>Recruitment variability of the early life history stages of marine benthic organisms can have profound consequences on population dynamics. I studied factors affecting recruitment success of postlarvae and early juveniles of the Caribbean spiny lobster. I examined patterns in postlarval supply, …
