Development And Application Of A Gis-Based Long Island Sound Eelgrass Habitat Suitability Index Model, Jamie M.P. Vaudrey, Justin Eddings, Christopher Pickerell, Lorne Brousseau, Charles Yarish
Department of Marine Sciences
The primary objectives of the Eelgrass Habitat Suitability Index Model (EHSI Model) are to assist in the evaluation of sites being considered for eelgrass restoration efforts in the Long Island Sound (LIS) area and to identify areas where water quality issues reduce or eliminate the potential for natural eelgrass colonization. To achieve this goal, geospatial processing of data available from the Long Island Sound area was conducted using ArcGIS v10.0 including the 3D Analyst and Spatial Analyst extensions. The result is a series of maps presented in this report and a GIS-based model available for users to interact with the …

The General Qapp For Long Island Sound Volunteer Coastal Monitoring (With Adoption Form), Jamie M.P. Vaudrey, Kimberly Gallagher
Department of Marine Sciences
The General QAPP for Long Island Sound Volunteer Coastal Monitoring is designed to streamline the process of writing a QAPP for Monitoring Programs in the Long Island Sound area. This document does not replace guidance on developing a program and is not sufficient as a stand-alone document to guide the initial development and sample design process for a monitoring program.
Evaluation Of Current Community-Based Monitoring Efforts And Recommendations For Developing A Cohesive Network Of Support For Monitoring Long Island Sound Embayments., Jamie M.P. Vaudrey, Jamie Alonzo, Adrienne Esposito, Curt Johnson, Maureen Dolan Murphy, Charles Yarish

This project focuses on Long Island Sound embayments and represents an exploration of the potential for coordination among community-based water quality monitoring groups, and coordination between community-based groups and data end users, including scientists and managers. Community-based monitoring groups represent a potential valuable source of water quality information. The development of standardized protocols, training methods and reporting procedures will serve to provide end users with the confidence necessary to utilize the data collected as part of community-based monitoring programs. Both groups of stakeholders stand to benefit from this type of coordination with the ultimate benefit being a healthier, better understood …
The Effect Of Landlocking On Intestinal Aquaporin 1 Expression In Alosa Pseudoharengus (Alewife), Emily Funk
The Effect Of Landlocking On Intestinal Aquaporin 1 Expression In Alosa Pseudoharengus (Alewife), Emily Funk
Honors Scholar Theses
To determine the role of intestinal aquaporin 1 (AQP1), a passive water absorption channel, in the evolution of osmoregulatory physiology, I examined the differential expression of intestinal AQP1 between anadromous and landlocked ecotype of alewife in response to seawater challenges. I cloned and sequenced AQP1 from intestinal tissue of the alewife, following which I quantified the relative expression of AQP1 in each ecotype using Real-Time qPCR. In response to an acute seawater (30ppt) challenge, the anadromous alewives showed an upregulation of intestinal AQP1, while the landlocked alewives did not show a significant increased in AQP1 expression. After …

Direct And Indirect Selection On Floral Pigmentation By Pollinators And Seed Predators In A Color Polymorphic South African Shrub, Jane E. Carlson, Kent E. Holsinger
Direct And Indirect Selection On Floral Pigmentation By Pollinators And Seed Predators In A Color Polymorphic South African Shrub, Jane E. Carlson, Kent E. Holsinger
EEB Articles
The coexistence of different color morphs is often attributed to variable selection pressures across space, time, morph frequencies or selection agents, but the routes by which each morph is favored are rarely identified. In this study we untangle the interactions and trait pleiotropisms that influence floral color polymorphisms on a local scale in Protea, within which ~40% of species are polymorphic. Previous work shows that seed predators and reproductive differences likely influence polymorphism maintenance in four Protea species. Here, we explore whether selection acts on floral color directly or indirectly in Protea aurea, using path analysis of pollinator …
Euryhalinity In An Evolutionary Context, Eric T. Schultz, Stephen D. Mccormick
Euryhalinity In An Evolutionary Context, Eric T. Schultz, Stephen D. Mccormick
EEB Articles
This chapter focuses on the evolutionary importance and taxonomic distribution of euryhalinity. Euryhalinity refers to broad halotolerance and broad halohabitat distribution. Salinity exposure experiments have demonstrated that species vary tenfold in their range of tolerable salinity levels, primarily because of differences in upper limits. Halotolerance breadth varies with the species’ evolutionary history, as represented by its ordinal classification, and with the species’ halohabitat. Freshwater and seawater species tolerate brackish water; their empirically-determined fundamental haloniche is broader than their realized haloniche, as revealed by the halohabitats they occupy. With respect to halohabitat distribution, a minority of species (<10%) are euryhaline. Habitat-euryhalinity is prevalent among basal actinopterygian fishes, is largely absent from orders arising from intermediate nodes, and reappears in the most derived taxa. There is pronounced family-level variability in the tendency to be halohabitat-euryhaline, which may have arisen during a burst of diversification following the Cretaceous-Palaeogene extinction. Low prevalence notwithstanding, euryhaline species are potent sources of evolutionary diversity. Euryhalinity is regarded as a key innovation trait whose evolution enables exploitation of new adaptive zone, triggering cladogenesis. We review phylogenetically-informed studies that demonstrate freshwater species diversifying from euryhaline ancestors through processes such as landlocking. These studies indicate that some euryhaline taxa are particularly susceptible to changes in halohabitat and subsequent diversification, and some geographic regions have been hotspots for transitions to freshwater. Comparative studies on mechanisms among multiple taxa and at multiple levels of biological integration are needed to clarify evolutionary pathways to, and from, euryhalinity.
