The Dynamics Of Bay Anchovy In The Hudson River Estuary: Process-Oriented Studies And Long-Term Changes, Eric T. Schultz, Kamazima M. M. Lwiza, John R. Young, Kyle J. Hartman, R. C. Tipton

EEB Articles

We review three areas of recent research on Hudson River bay anchovy. One focus has been the along-estuary movement of early life stages. A cohort analysis of samples collected in a spatiotemporally extensive monitoring program has confirmed that early-stage anchovy migrate up-estuary, at an estimated rate of 0.6 km/d. Complementary fine-scale field sampling was designed to clarify behaviors that effect the migration. This work found that early-stage anchovy can show preferences for depth and can conduct periodic vertical migration. To determine whether these behaviors were sufficient to produce up-estuary migration, larval flux and velocity were estimated. These estimates were consistent …

Assessment Of Anti-Poaching Effort In Ruaha National Park, Tanzania, C. L. Nahonyo

Tanzania Journal of Science

Anti-poaching effort in Ruaha National Park for the period between January 1996 to June 1999 was evaluated in terms of strength, frequency and duration of patrols, area covered and success of patrols. It was found that the park spent 72.4 US$ km-2 year-1 on law enforcement. There were 72 rangers each required to patrol on the average 143 km2. A total of 1,255 patrols were conducted; patrols ranged from 14 to 43 trips per month and each lasted between 1 to 25 days and most were foot and vehicle patrols. Patrol units had 2 to 11 rangers while the average …

Spatial Autocorrelation Of Deer-Vehicle Accidents In Vigo County, J. Scott Horn

All-Inclusive List of Electronic Theses and Dissertations

Deer-vehicle accidents (DV As) are a problem in many areas. They cause millions of dollars in property damage, personal injury, and loss of life each year. This thesis examines whether DVAs in Vigo County, Indiana during the year 2000 were spatially autocorrelated; and whether DV As selected by deer habitat were spatially autocorrelated. Specifically using Moran's I to test for spatial autocorrelation this study determined if and to what degree spatial autocorrelation existed among these DVAs. A Moran's I value of .0023 shows that the accidents occurred randomly. These DV A data were then used to plot a map which …

The purpose of this project was to collect the biological and fishery information necessary to conduct a stock assessment of the sandbar (known locally as ‘thickskin’) shark, Carcharhinus plumbeus and to improve and update the existing stock assessment for the dusky shark, Carcharhinus obscurus. Results from this project have already been used by the Western Australian Department of Fisheries to determine appropriate management arrangements for the State’s shark fisheries to ensure the sustainable exploitation of these species. Results have also assisted the WA target-shark fisheries in conducting Ecologically Sustainable Development (ESD) assessment in order …

Celastrina Serotina (Lycaenidae: Polyommatinae): A New Butterfly Species From The Northeastern United States And Eastern Canada, Harry Pavulaan, David M. Wright

The Taxonomic Report of the International Lepidoptera Survey

A new light-venter Azure species, Celastrina serotina, is described from the northeastern United States and eastern Canada. The flight period of this univoltine spring species is interpolated (allochrony) between its sympatric congeners, C. lucia Auctorum (not Kirby) and C. neglecta (Edwards). In this regard it is similar to C. neglectamajor Opler & Krizek in the southern Appalachians and C. idella Wright & Pavulaan on the New Jersey coastal plain. In a significant portion of its range, C. serotina larvae feed on eriophyid mite-formed galls on the upper surface of Black Cherry Prunus serotina Ehrh. …

Comparing Immune Responses Of Juvenile And Adult Northern Fence Lizards, Sceloporus Undulatus, Zaïna Sandrine Kabange

All-Inclusive List of Electronic Theses and Dissertations

Sex steroid hormones affect behavior and morphological traits important in sexual selection. Steroid hormones also play a role in the development and functioning of immune system components. The immunocompetence handicap hypothesis (Folstad and Karter, 1992) proposes that tradeoffs, mediated by plasma levels of testosterone, exist between the immune system and elaboration of secondary sexual traits. Endocrine-immune interactions are well documented in birds and mammals, and steroid hormones can be immunoenhancing or immunosuppressive. Relatively little work has examined the ontogeny of immune function, and the interactions between steroid hormones and the immune system in reptiles. The first experiment addressed the question …

Seagrass–Pathogen Interactions: ‘Pseudo-Induction’ Of Turtlegrass Phenolics Near Wasting Disease Lesions, Latina Steele, Melanie Caldwell, Anne Boettcher, Tom Arnold

Biology Faculty Publications

Marine protists of the genus Labyrinthula cause the seagrass wasting disease, which is associated with regional die-offs of eelgrass Zostera marina and also infects turtlegrass Thalassia testudinum . The ability of seagrasses to resist pathogen attack is determined by multiple factors, which are poorly understood. One factor hypothesized to influence seagrass disease resistance is the presence of (poly)phenolic natural products such as caffeic acid, which inhibits the growth of L. zosterae in in vitro laboratory bioassays. This hypothesis has been supported by reports of pathogen-induced phenolic accumulations in eelgrass Z. marina. To test the response of T. testudinum to …

Cortical Complexity In Cetacean Brains, Patrick R. Hof, Rebecca Chanis, Lori Marino

Veterinary Science and Medicine Collection

Cetaceans (dolphins, whales, and porpoises) have a long, dramatically divergent evolutionary history compared with terrestrial mammals. Throughout their 55–60 million years of evolution, cetaceans acquired a compelling set of characteristics that include echolocation ability (in odontocetes), complex auditory and communicative capacities, and complex social organization. Moreover, although cetaceans have not shared a common ancestor with primates for over 90 million years, they possess a set of cognitive attributes that are strikingly convergent with those of many primates, including great apes and humans. In contrast, cetaceans have evolved a highly unusual combination of neurobiological features different from that of primates. As …

Development Of Biological Reference Conditions Of Wadeable Streams In The Major Ecoregions And Subecoregions Of Georgia, Duncan L. Hughes

Theses and Dissertations

One bioassessment tool available to resource managers to indicate NPS impairment of wadeable streams and rivers are multi-metric invertebrate indices. Such indices are assembled from metrics in broad categories that represent different aspects of community structure and function (e.g. richness, composition, tolerance/intolerance, feeding group, and habit). Indices must incorporate suites of metrics that are ecologically relevant, quantifiable, non-redundant, and that best individually discriminate between reference sites and impaired sites. More than 240 wadeable streams in Georgia were sampled during the September thru February index period using RBP protocols during three successive sample seasons (1999-2003). Ecoregional reference (minimally impaired) sites, as …

Ecological Costs And Benefits Of Defenses In Nectar, Lynn S. Adler, Rebecca E. Irwin

Dartmouth Scholarship

The nectar of many plant species contains defensive compounds that have been hypothesized to benefit plants through a variety of mechanisms. However, the relationship between nectar defenses and plant fitness has not been established for any species. We experimentally manipulated gelsemine, the principal alkaloid of Carolina jessamine (Gelsemium sempervirens), in nectar to determine its effect on pollinator visitation, nectar robber visitation, and male and female plant reproduction. We found that nectar robbers and most pollinators probed fewer flowers and spent less time per flower on plants with high compared to low nectar alkaloids. High alkaloids decreased the donation of fluorescent …

Impact Of Bythotrephes Invasion On Zooplankton Communities In Acid-Damaged And Recovered Lakes On The Boreal Shield, Angela L. Strecker, Shelley E. Arnott

Environmental Science and Management Faculty Publications and Presentations

Invasive species introductions into freshwater ecosystems have had a multitude of effects on aquatic communities. Few studies, however, have directly compared the impact of an invader on communities with contrasting structure. Historically high levels and subsequent reductions of acid deposition have produced landscapes of lakes of varying acidity and zooplankton communitystructure. We conducted a 30-day enclosure experiment in Killarney Provincial Park, Ontario, Canada, to test the effects ofBythotrephes longimanus, an invasive invertebrate predator, on two contrasting zooplankton communities at different stages of recovery from acidification: recovered and acid damaged. Bythotrephes significantly decreased zooplankton biomass and abundance in both communities but …

Fisheries Occasional Publication No. 32 - Allocation Of The Western Australian Abalone Resource Between User Groups, Department Of Fisheries Western Australia

Fisheries Occasional Publications

In this submission to the Integrated Fisheries Allocation Advisory Committee (IFAAC), the Department will outline what it believes are the most practical and cost effective ways of managing a system for allocating the abalone resource between the commercial, customary and recreational sectors.

In preparing this submission, it has been noted that because of the limited data on recreational catch outside of the metropolitan area, the Sustainable Harvest Limit (SHL) set for the fishery relates only to the area that is equivalent to Area 7 of the commercial fishery. Further, it is acknowledged that the Minister has approved that proportional catch …

A Phylogenetic Analysis Of Vanzolinius Heyer, 1974 (Amphibia, Anura, Leptodactylidae): Taxonomic And Life History Implications, Rafael O. De Sá, W. Ronald Heyer, Arley Camargo

Biology Faculty Publications

The validity of the monotypic leptodactylid frog genus Vanzolinius Heyer, 1974 has been questioned recently. We explore the relationship of Vanzolinius discodactylus within the cluster of closely related genera Adenomera, Leptodacylus, and Lithodytes with both morphological and molecular data sets. Morphological and combined morphological and molecular data were analyzed using maximum parsimony; molecular data sets were analyzed with maximum likelihood methods. The resultant relationships are unambiguous in Vanzolinius being imbedded within Leptodactylus. In order to maintain Leptodactylus as a monophyletic genus, Vanzolinius is placed in the synonymy of Leptodactylus Fitzinger, 1826. The implications of relationships analyzed in …

Biodemography Of A Long-Lived Tephritid: Reproduction And Longevity In A Large Cohort Of Female Mexican Fruit Flies, Anastrepha Ludens, James R. Carey, Pablo Liedo, Hans-Georg Müller, Jane-Ling Wang, Damla Senturke, Lawrence G. Harshman

Lawrence G. Harshman Publications

Age of sexual maturity, daily and lifetime reproductive rates, and life span were recorded in a laboratory cohort of Mexican fruit flies consisting of over 1100 females maintained individually. The results revealed that, relative to the medfly, the Mexfly is slower maturing (14 vs 17 days), more fecund (1400 vs 650–1100 eggs/female), and longer lived (50 vs 35 days). The results reinforced the generality of several earlier findings on the medfly including the deceleration of mortality at older ages and the weakness of the correlation between the rate of egg laying at early ages and both subsequent reproduction and remaining …

The Effect Of Human Predation, Rats And Goats On Small Colonies Of Wedge-Tailed Shearwaters (Puffinus Pacificus) In Southwest Madagascar, Alexis P. Will

Independent Study Project (ISP) Collection

Three islands: Betsiboko, Jamanjaky Be and Jamanjaky Roa, off the coast of Morombe in Southwest Madagascar were visited in November 2005 to verify the existence and evaluate the health of wedge-tailed shearwater (Puffinus pacificus) colonies that were described by Otto Appert in the 1960’s (Hawkins (a) 2005; Hawkins (b) 2005). These three islands experience varying degrees of human use, ranging from low: light human predation on shearwater chicks, to high: the presence of domestic animals, collecting fuelwood on the island and more intensive harvesting of chicks. Interviews were conducted with the local Vezo (fishing) people to quantify the human predation …

The Symmetry Of Longevity, Lawrence G. Harshman, Hans-Georg Müller, Xueli Liu, Yue Wang, James R. Carey

Lawrence G. Harshman Publications

We tested the hypothesis that relatively symmetrical flies live longer. Vein measurements on the left and right wings from the same individual were used to characterize bilateral symmetry in relationship to age-specific survival in defined cohorts. A longitudinal cohort study supported the hypothesis of a correlation between bilateral symmetry and longevity. For another type of experiment, wings were removed from females and males at approximately the beginning of adult life. Thus, there would be no effect of wings per se on adult survival. These wings were measured to characterize bilateral asymmetry, and the day of death of each dewinged individual …

Redescripción De La Morfología Larval Externa De Dos Especies Del Grupo De Leptodactylus Fuscus (Anura, Leptodactylidae), José A. Langone, Rafael O. De Sá

Biology Faculty Publications

Re-description of the larval external morphology of two species of the Leptodactylus fuscus group (Anura, Leptodactylidae). The larvae of Leptodactylus gracilis (D’Orbigny y Bibron, 1840) and L. mystacinus Bumeister, 1861 are re-described and compared with previous descriptions noting intraspecific variation in oral disc characteristics (arrangement of papillae and rows of cornified teeth). The external morphological analysis of larvae of the Leptodactylus fuscus group suggest that the lack of comparable descriptions among species, as well as the lack of analyses of their intraspecific variation, limits the use of larval characteristics for diagnostic purposes.
