Variation in Winter Estuarine Habitat Use by Bluefish in Northeastern Florida with Implications for Growth and Condition
bluefish winter ecology age growth condition
2014/12/11
Age and growth were determined from otoliths for 181 juvenile bluefish, Pomatomus saltatrix, collected using a variety of gear in northeast Florida during 2003 and 2005. Three distinct cohorts were id...
Invertebrate Phenology and Prey Selection of Three Sympatric Species of Salmonids; Implications for Individual Fish Growth
Invertebrate Phenology Prey Selection Three Sympatric Species Salmonids Individual Fish Growth
2014/12/11
Growth plays an important roll in the survival of individual salmonid fish. Diet inevitably plays a significant role in the determination of salmonid growth, with these diets consisting primarily of a...
Growth of Atlantic Salmon (Salmo salar) in Freshwater

2014/11/26
Developing quantified establishment period estimates for newly planted trees will help set realistic goals for plant performance in the urban landscape. Nine years of tree planting records obtained fr...
Scientists have long been trying to understand how the Andes and other broad, high-elevation mountain ranges were formed. New research by Carmala Garzione, a professor of earth and environmental scien...
Cross-ecosystem differences in lipid composition and growth limitation of a benthic generalist consumer
Cross-ecosystem differences lipid composition growth limitation benthic generalist consumer
2014/4/2
In a field study, we analyzed the fatty acid (FA) composition of the benthic generalist Asellus aquaticus collected from boreal lakes, ponds, and streams across gradients in ambient nutrient levels. I...
Assessing the Sensitivity of Climate Change Targets to Policies of Land Use, Energy Demand, Low Carbon Energy and Population Growth
Climate Change Policy Sensitivity Analysis
2013/3/12
A reduced scale model of the coupled carbon cycle, population dynamics, energy system and land use characteristics is used to assess the sensitivity of atmospheric carbon to a variety of policies. Pol...
Growth Kinetics of Wildlife E. coli Isolates in Soil and Water
