Assessment Of Anadromous Alewife And Blueback Herring Populations In Connecticut Coastal Streams And Connecticut River Tributaries, Justin P. Davis, Eric T. Schultz

EEB Articles

Alewife (Alosa pseudoharengus) and blueback herring (A. aestivalis) occur in anadromous populations that have a largely overlapping distribution from Florida to Newfoundland (Loesch 1987). Anadromous populations of these species are commonly collectively referred to as “river herring”. Adults inhabit coastal shelf waters until sexual maturity is reached at age 3-5 (Neves 1981). Sexually mature individuals make spawning migrations, commonly referred to as “runs”, into freshwater systems during spring months (Loesch 1987). Spawners can survive and return to spawn in subsequent years (Mullen et al. 1986). Juveniles reside in freshwater for 3-7 months, at which time they undertake a gradual migration …

The Natural History And Thermal Ecology Of A Population Of Spotted Turtles (Clemmys Guttata) And Wood Turtles (Glyptemys Insculpta) In West Virginia, Ariana N. Breisch

Theses, Dissertations and Capstones

An ecological study was conducted from 19 March 2001 to 2 April 2003 on a population of Spotted Turtles (Clemmys guttata) and Wood Turtles (Glyptemys insculpta) in West Virginia. Live-trapping, mark-recapture, radio telemetry and temperature data logging techniques were used to gather information on morphometrics, capture success, movements, home range, behavior, and thermal regime during activity and over-wintering seasons. Twenty-one Spotted Turtles were captured 260 times. Population structure was 42.9% juvenile, 38.1% male, and 19.0% female. Mean home range was 0.52 ha. Fifty Wood Turtles were captured 230 times. Juveniles were 36%, and males and females were 32% each. Mean …

Feeding Habits Of Common Snook, Centropomus Undecimalis, In Charlotte Harbor, Florida, David A. Blewett, Rebecca A. Hensley, Philip W. Stevens

Gulf and Caribbean Research

We examined the feeding habits, ontogenetic and seasonal diet variations, and predator size–prey size relationships of common snook, Centropomus undecimalis, in Charlotte Harbor, Florida, through stomach contents analysis. A total of 694 stomachs were extracted from common snook (300–882 mm standard length [SL]) during a 24-month period (March 2000–February 2002); 432 stomachs contained prey items. At least 37 prey taxa were identified, including 19 that had not been previously reported. Fishes made up 71% of the prey by number and 90% by weight. Three prey items made up almost 50% of the diet numerically—Lagodon rhomboides, Anchoa spp., …

Phytoremediation: An Affordable Green Technology For The Clean-Up Of Metal-Contaminated Sites In Sri Lanka, Nishanta Rajakaruna, Kathleen M. Tompkins, Peter G. Pavicevic

Biological Sciences

Phytoremediation, the use of plants to remediate sites contaminated with organic and inorganic pollutants, and phytomining, the technology involved in extracting the pollutants removed for commercial purposes, are rapidly-growing industries with multi-million dollar markets. This solar-driven, green technology is oftenfavored over more conventional methods of clean-up due to its low cost, low impact, and wider public acceptance. In this paper we discuss phytoremediation as a valid alternative for remediating contaminated bodies of soils and water in developing countries like Sri Lanka, where clean-up can often be stalled due to the high costs associated with traditional remediation technologies. While phytoremediation techniques …

Interpolation Of Tracking Data In A Fluid Environment, Y Tremblay, Scott A. Shaffer, S L. Fowler, C E. Kuhn, B I. Mcdonald, M J. Weise, C -A Bost, H Weimerskirch, D E. Crocker, M E. Goebel, D P. Costa

Faculty Publications, Biological Sciences

Interpolation of geolocation or Argos tracking data is a necessity for habitat use analyses of marine vertebrates. In a fluid marine environment, characterized by curvilinear structures, linearly interpolated track data are not realistic. Based on these two facts, we interpolated tracking data from albatrosses, penguins, boobies, sea lions, fur seals and elephant seals using six mathematical algorithms. Given their popularity in mathematical computing, we chose Bézier, hermite and cubic splines, in addition to a commonly used linear algorithm to interpolate data. Performance of interpolation methods was compared with different temporal resolutions representative of the less-precise geolocation and the more-precise Argos …

Early Ontogenetic Diet In Gray Wolves, Canis Lupus, Of Coastal British Columbia, Heather M. Bryan, Chris T. Darimont, Thomas E. Reimchen, Paul C. Paquet

Biogeography and Ecological Opportunity Collection

Within populations, different age classes often consume dissimilar resources, and provisioning of juveniles by adults is one mechanism by which this can occur. Although the diet of Gray Wolves (Canis lupus) has been studied extensively, the diet of pups is largely unknown. We examined faeces deposited by altricial pups and adult providers during the first two months following birth at two den sites over two years on the central coast of British Columbia, Canada. Pups and adult wolves consumed similar species, and Black-tailed Deer (Odocoileus hemionus) constituted most of the diet for both age groups. Pup and adult diet, however, …

Further Evidence For Seed Size Variation In The Genus Zostera: Exploratory Studies With Z. Japonica And Z. Asiatica, Sandy Wyllie-Echeverria, Victoria R. Wyllie-Echeverria, Algernon C. Churchill, Paul A. Cox

Aliso: A Journal of Systematic and Floristic Botany

Recent studies found seed size variation within the seagrass Zostera marina, one of nine species in the genus Zostera. The objectives of this study were to determine if variation also exists in the seeds of two other species Zostera japonica and Zostera asiatica within this genus. Results indicate that: (1) length and weight varied between two populations (one indigenous population from Akkeshi-Ko, Japan, and one exotic population from Willapa Bay, Washington, USA) of the small-bodied intertidal seagrass species Z. japonica, and (2) seed-size classes were discernable. Preliminary investigations were also initiated with a Japanese population of Z. asiatica …

Structural Response Of Caribbean Dry Forests To Hurricane Winds: A Case Study From Guanica Forest, Puerto Rico, Skip Van Bloem, Ariel E. Lugo, Peter G. Murphy

Publications

Tropical dry forests in the Caribbean have an uniquely short, shrubby structure with a high proportion of multiple-stemmed trees compared to dry forests elsewhere in the Neotropics. Previous studies have shown that this structure can arise without the loss of main stems from cutting, grazing, or other human intervention. The Caribbean has a high frequency of hurricanes, so wind may also influence forest stature. Furthermore, these forests also tend to grow on soils with low amounts of available phosphorus, which may also influence structure. The objective of this study was to assess the role of high winds in structuring dry …

Spatial Autocorrelation And Pseudoreplication In Fire Ecology, Amanda L. Bataineh, Brian P. Oswald, Mohammad M. Bataineh, Daniel Unger, I-Kuai Hung, Daniel Scognamillo

Faculty Publications

Fire ecologists face many challenges regarding the statistical analyses of their studies. Hurlbert (1984) brought the problem of pseudoreplication to the scientific community’s attention in the mid 1980’s. Now, there is a new issue in the form of spatial autocorrelation. Spatial autocorrelation, if present, violates the traditional statistical assumption of observational independence. What, if anything, can the fire ecology community do about this new problem? An understanding of spatial autocorrelation, and knowledge of available methods used to reduce the effect of spatial autocorrelation and pseudoreplication will greatly assist fire ecology researchers.

Fastgroupii: A Web-Based Bioinformatics Platform For Analyses Of Large 16s Rdna Libraries, Yanan Yu, Mya Breitbart, Pat Mcnairnie, Forest Rohwer

Marine Science Faculty Publications

Background: High-throughput sequencing makes it possible to rapidly obtain thousands of 16S rDNA sequences from environmental samples. Bioinformatic tools for the analyses of large 16S rDNA sequence databases are needed to comprehensively describe and compare these datasets.

Results: FastGroupII is a web-based bioinformatics platform to dereplicate large 16S rDNA libraries. FastGroupII provides users with the option of four different dereplication methods, performs rarefaction analysis, and automatically calculates the Shannon-Wiener Index and Chao1. FastGroupII was tested on a set of 16S rDNA sequences from coral-associated Bacteria. The different grouping algorithms produced similar, but not identical, results. This suggests that 16S …

Speciation In Duckweeds (Lemnaceae): Phylogenetic And Ecological Inferences, Daniel J. Crawford, Elias Landolt, Donald H. Les, Rebecca T. Kimball

Aliso: A Journal of Systematic and Floristic Botany

Species of duckweeds (Letnnaceae) that were resolved as sister taxa in a phylogeny based on combined molecular and non-molecular data were compared for morphological, physiological, and ecological attributes to infer factors important in the initial divergence leading to speciation. The ability to survive extreme conditions such as desiccation and cold temperatures is the most common difference identified between species. Two morphological characters facilitating survival in extreme environments are production of special resting buds called turions and increased seed production. The prevalent geographic pattern for species pairs consists of one restricted species occurring on the periphery of a more widespread taxon; …

Biodiversity Loss And The Taxonomic Bottleneck: Emerging Biodiversity Science, Ke Chung Kim, Loren B. Byrne

Arts & Sciences Faculty Publications

Human domination of the Earth has resulted in dramatic changes to global and local patterns of biodiversity. Biodiversity is critical to human sustainability because it drives the ecosystem services that provide the core of our life-support system. As we, the human species, are the primary factor leading to the decline in biodiversity, we need detailed information about the biodiversity and species composition of specific locations in order to understand how different species contribute to ecosystem services and how humans can sustainably conserve and manage biodiversity. Taxonomy and ecology, two fundamental sciences that generate the knowledge about biodiversity, are associated with …

Our Places To Tell Stories: Making Connections With Our Audiences, Public Lands Institute

Our Places to Tell Stories

The idea for an annual Our Places Tell Stories conference was prompted by discussions that took place within a unique partnership of federal, state, university, and public organizations in southern Nevada. Members identified the need to share and learn from successful educational and interpretive strategies. Our increasingly urban surroundings and rapidly changing populations hinder personal connections between people and their natural environment. However, the right tools and techniques will help us inspire children and adults to understand, value, and take care of our shared natural places.

This first conference supports professionals in creating and evaluating effective educational programs and interpretive …

Asymmetric Vegetation Responses To Mid-Holocene Aridity At The Prairie-Forest Ecotone In South-Central Minnesota, Charles Umbanhowar, Phil Camill, Christoph Geiss, Rebecca Teed

Biology Faculty Work

The mid-Holocene (ca. 8000–4000 cal yr BP) was a time of marked aridity throughout much of Minnesota, and the changes due to midHolocene aridity are seen as an analog for future responses to global warming. In this study, we compare the transition into (ca. 9000–7000 yr ago) and out of (ca. 5000–2500 yr ago) the mid-Holocene (MH) period at Kimble Pond and Sharkey Lake, located along the prairie forest ecotone in south-central Minnesota, using high resolution (∼5–36 yr) sampling of pollen, charcoal, sediment magnetic and loss-on-ignition properties. Changes in vegetation were asymmetrical with increasing aridity being marked by a pronounced …

A Practical Look At The Variable Area Transect, Solomon Z. Dobrowski, Shannon K. Murphy

Forest Management Faculty Publications

The variable area transect (VAT) is a plotless density estimator that has received little attention in the ecological literature despite having potentially robust estimation properties. VAT allows for density estimations without the lengthy search times associated with other plotless density estimators. In spite of this, little has been written about the effect of varying transect widths on its density estimation properties or on the practical implementation of the VAT in field settings. An artificial population sampler was used to examine the effect of transect width on density estimates obtained using the VAT. Three transect widths were chosen corresponding to the …
