Flight of the Freshwater Fish

The Hudson River provides for millions of people as a path for commercial and private transportation, a source of food and energy, and perhaps most importantly for many living in the tri-state area as a destination for recreation and relaxation. The most overlooked feature of the river is how the wildlife shows clear signs of a changing climate and rapid environmental response to the impacts of global warming on the river.

Entire populations of fish species in the lower Hudson have been forced to leave the river …

Ecology Of Sceloporus Consobrinus Populations In Two Thermally Different Habitats, Alyssa N. Bangs

Theses and Dissertations from 2016

Life history traits in ectotherms are tied to environmental temperature, and many species exhibit morphological and behavioral differences in thermally different habitats. Although these differences are generally attributed to differences in thermal regimes between habitats, most prior research on this topic has been performed across latitudinal or altitudinal gradients. Consequently, I wanted to determine if differences in morphology and behavior are also present among populations of Sceloporus consobrinus that inhabit thermally different habitats at the same latitude and elevation. In this study, I chose sites that fit one of two habitat types: warmer open rocky habitat and cooler, more vegetated …

Evolution In Light Of Mitonuclear Landscapes: An Examination Of Mitochondrial Replacement In Killifish (Fundulus Spp.), Stephen D. Flanagan

Dissertations

The mitochondria are responsible for the bulk of energy production in eukaryotes. They possess their own genome that works in conjunction with the nuclear genome to accomplish the extraordinarily important task of energy conversion. When species hybridize there will be a mismatch in evolutionary histories between these two genomes. The deleterious interactions of these genomes have been studied in great detail (i.e. hybrid breakdown). However, little work has been conducted to understand the population genetic, and morphological consequences of wide-ranging replacement. The Fundulus notatus complex is comprised of 3 species: F. notatus, F. olivaceus, and F. euryzonus. …

An Analysis Of Morphometric Differentiation In Lake And River Populations Of The Emerald Shiner, Notropis Atherinoides, John J.V. Lang

Biology Theses

Understanding mechanisms that account for phenotypic variation has been of interest to biologists since the advent of Darwin’s theory of evolution by natural selection. It is now understood that adaptive divergence is a key driving force of intraspecific differentiation. Further, differences in habitat (e.g., flow regime, prey regime) have been shown to drive adaptive divergence in fish. For instance, fish inhabiting faster flowing water generally exhibit more fusiform bodies than their lake counterparts. Similarly, the partitioning of benthic and pelagic morphs generally results in smaller heads with the latter. This study used geometric shape analysis to assess morphological differences between …

Distribution, Abundance, And Migration Timing Of Greater And Lesser Sandhill Cranes Wintering In The Sacramento–San Joaquin River Delta Region Of California, Gary L. Ivey, Bruce D. Dugger, Caroline P. Herziger, Michael L. Casazza, Joseph P. Fleskes

Proceedings of the North American Crane Workshop

The Sacramento-San Joaquin River Delta region of California (hereafter, Delta region) is an important wintering region for the Central Valley Population of greater sandhill cranes (Grus canadensis tabida) and lesser sandhill cranes (G. c. canadensis), but basic information about the ecology of these birds is lacking to design a biologically sound conservation strategy. During the winters of 2007-08 and 2008-09, we conducted roost counts, roadside surveys, aerial surveys, and tracked radio-marked birds to define the geographic area used by sandhill cranes in the Delta region, document migration chronology, and estimate subspecies-specific abundance. Radio-marked sandhill cranes arrived in our study area …

Kin Selection And Its Discontents, David C. Queller

Biology Faculty Research

Kin selection is a core aspect of social evolution theory, but a small number of critics have recently challenged it. Here I address these criticisms and show that kin selection remains an important explanation for much (though not all) social evolution. I show how many of the criticisms rest on historical idiosyncrasies of the way the field happened to develop, rather than on the real logic and evidence.

Diversity And Impacts Of Mining On The Non-Volant Small Mammal Communities Of Two Vegetation Types In The Brazilian Amazon, Natália Carneiro Ardente, Átilla Colombo Ferreguetti, Donald Gettinger, Pricila Leal, Ana Cristina Mendes-Oliveira, Fernanda Martins-Hatano, Helena Godoy Bergallo

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The CarajaÂs National Forest contains some of the largest iron ore deposits in the world. The majority of the minerals are found below a plant community known as Savana Metalo fila, or ªCangaº, which represents only 3% of the landscape within the CarajaÂs National Forest (CNF). The aim of our study was to understand the diversity of community of non-volant small mammals in the two predominant vegetation types: Ombrophilous Forest and Canga, and to examine how mining impacts these communities. Sampling was conducted from January 2010 to August 2011 in 11 sampling sites divided by the total area of Canga …

First Occurrence Of The Invasive Hydrozoan Gonionemus Vertens A. Agassiz, 1862 (Cnidaria: Hydrozoa) In New Jersey, Usa, John J. Gaynor, Paul A.X. Bologna, Dena J. Restaino, Christie Barry

Department of Biology Faculty Scholarship and Creative Works

Gonionemus vertens A. Agassiz, 1862 is a small hydrozoan native to the Pacific Ocean. It has become established in the northern and southern Atlantic Ocean as well as the Mediterranean Sea. We report on the first occurrence of this species in estuaries in New Jersey, USA,and confirm species identification through molecular sequence analysis. Given the large number of individuals collected, we contend that this is a successful invasion into this region with established polyps. The remaining question is the vector and source of these newly established populations.

Monk Parakeets, Michael L. Avery, James R. Lindsay

Wildlife Damage Management Technical Series

Since their introduction to the United States in the 1960s, monk parakeets (Myiopsitta monachus) have thrived (Figure 1). Until recently, annual Christmas Bird Count data have shown the population to be increasing exponentially. In the U.S., monk parakeets are an urban and suburban species with few natural predators, diseases or other factors limiting their population growth. They exploit backyard bird feeders and non-native ornamental plants for food. Monk parakeets often construct nests on man-made structures, such as electric utility facilities and cell phone towers. Because the birds build and maintain nests throughout the year, management of parakeet populations …

Parajulid Milliped Studies Xi: Initial Assessment Of The Tribe Gosiulini (Diplopoda: Julida), Rowland M. Shelley, Jamie M. Smith

Insecta Mundi

The parajulid milliped tribe Gosiulini (Diplopoda: Julida) comprises two genera – Gosiulus Chamberlin, with three projections on the posterior gonopod and two species in the southcentral/southwestern United States (US) [Arizona, Colorado, New Mexico, and Texas], and monotypic Minutissimiulus Shelley, n. gen., with two projections, in Nuevo León, Mexico. Gosiulus conformatus Chamberlin occupies the plains/fl atlands of Texas, while its congener inhabits high elevations to the west in all four US states. Both are anticipated in Mexico (Coahuila, Chihuahua, and Sonora), and G. conformatus is expected in southeastern Colorado, eastern New Mexico, and the Oklahoma panhandle. The eastern boundary …

Reproductive Schedule Of The Silver Shiner (Notropis Photogenis) In The Flint River Of Alabama, Kelly Hodgskins, Stephanie Greenleaf, Jonathan Hillman, Bruce Stallsmith

Southeastern Fishes Council Proceedings

Many river-dwelling species of fish are dependent upon and stimulated by fluctuations in river flow for successful reproduction. This is especially true of pelagophils, a reproductive guild whose eggs and larvae require free drifting on river currents for several days. Notropis photogenis (Silver Shiner) is a rheophilic species with a broad distribution from Ontario to the southeastern United States including northern tributaries to the Tennessee River in Alabama. Little is known of its reproductive biology. The purpose of this study was to describe aspects of reproductive biology such as timing and pattern of ovarian development and oocyte maturation of N. …

To Fish Or Not To Fish? What Effect Do California’S Marine Protected Areas Have On Up-And-Coming Kellet’S Whelk Fishery?, Jennifer Greene

STAR Program Research Presentations

Kellet’s whelk, Kelletia kelletii, were observed at sample sites throughout their range from Baja California, Mexico, to Monterey, CA to determine patterns of population density. Sample sites in each region were either located within California marine protected areas where take of the Kellet’s whelk in prohibited, or in non-protected areas where the whelks can be fished both commercially and recreationally. Kellet’s whelk population density was compared between all MPA and non-MPA sample sites. These mean densities were also found for sites in Santa Barbara and San Diego near active fishing ports and compared to data from the same sites collected …

Harpy Eagle (Harpia Harpyja) Conservation: Juvenile Behavior And Diet At A Nest Near Pijibasal, Darien, Hannah Rodgers

Independent Study Project (ISP) Collection

The Harpy Eagle (Harpia harpyja), the largest and most powerful bird of prey in the Americas, is declining throughout its range in Neotropical forests. Hunting and deforestation threaten populations in the most important remaining eagle habitat in Central America, the Darien province of Panama. These eagles may have the longest postfledging juvenile dependency of any raptor, though juvenile behavior during this period is poorly studied. This study monitored an 11-month-old juvenile for 7 days at a nest near the indigenous community of Pijibasal in order to study behavior and diet. Researchers recorded the juvenile’s location and behavior, studied prey remains …

Uncommon/Rare Avian Species Decline And Extirpation In Nested Assemblages Of Northeastern Illinois Wetlands, James M. Mcaley

All Capstone Projects

Baisa found that avian assemblages are highly nested in palustrine emergent wetlands in northeastern Illinois. He measured nestedness by constructing a binary matrix of species presence and absence across sites. Nestedness was also quantified using the Mann-Whitney U-test in his study.

The goal of this project was to sample the wetlands as Baisa had done in his study. By doing so, we will have 2 sampling events, approximately 10 years apart. Nestedness of the wetland communities will be checked, and data compared to that of Baisa. Emergent wetlands in northeastern Illinois were found by Baisa to contain highly nested avian …

Cedar Waxwings, Michael L. Avery, Anthony G. Duffiney

Wildlife Damage Management Technical Series

Prevention and control of cedar waxwing (Bombycilla cedrorum) damage to small fruits such as blueberry, cherry, and strawberry is vexing to growers in many parts of the United States. Cedar waxwings (Figure 1) travel in flocks and descend in large numbers on berry crops, especially during winter and migration. In short feeding bouts, waxwings eat, peck, or knock substantial amounts of fruit from the plants. These frugivores are difficult to discourage once they become established at a given location. Harassment early and often using pyrotechnics or other sudden noisemakers can help prevent flocks from being established. The most effective preventative …

Rabbit Control: Bait Stations, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

This factsheet provides information on using bait stations for rabbit control.

Biological control agents such as the myxoma virus (myxomatosis), and rabbit haemorraghic disease virus (RHDV) or rabbit calicivirus disease, will not provide ‘magic bullets’ for reducing the impact of rabbits on agricultural production and the environment. Biological agents are more effective when they form part of an integrated approach to rabbit control. An integrated approach should use all available control options, including biological control, the use of vertebrate pesticides, shooting, and trapping programs. Control programs are most effective when they include the greatest number of properties possible (that is, …

A Novel Qtl Associated With Dwarf Bunt Resistance In Idaho 444 Winter Wheat, Jianli Chen, Mary J. Guttieri, Junli Zhang, David Hole, Edward Souza, Blair Goates

Green Canyon Environmental Research Area, Logan Utah

Dwarf bunt [Tilletia controversa J.G. Kühn [as ‘contraversa’], in Rabenhorst, Hedwigia 13: 188 (1874)] is a destructive disease of wheat (Triticum aestivum L.) that reduces grain yield and quality. A number of distinct genes conferring resistance to dwarf bunt have been used by breeding programs for nearly 100 years. However, few markers were identified that can be used in selection of dwarf bunt resistance. A recombinant inbred line (RIL) population derived from the bunt-resistant germplasm, Idaho 444 (IDO444), and the susceptible cultivar, Rio Blanco, was evaluated for phenotypic reaction to dwarf bunt inoculation in four trials in …

Under Pressure: Cetaceans And Fisheries Co-Occurrence Off The Coasts Of Ghana And Côte D’Ivoire (Gulf Of Guinea), Marijke N. De Boer, James T. Saulino, Koen Van Waerebeek, Geert Aarts

Anthropogenics and Population Decline Collection

Within the Gulf of Guinea high levels of fisheries-related cetacean mortality (bycatch and direct-capture) has been documented. For locally rare species such removals could potentially lead to significant population level effects. However, information on the cetacean abundance and distribution is scarce. Similarly, it remains largely unreported where fishing fleets operate offshore. A cetacean survey took place during geophysical surveys (2013–2014) along the coasts of Ghana and Côte d’Ivoire. This provided a unique opportunity to study both offshore cetacean and fishing communities. Due to large group-sizes, melon-headed whales were the most abundant (0.34 animals km−1) followed by Fraser’s dolphins and short-finned …

The Utilization Of Aquatic Bushmeat From Small Cetaceans And Manatees In South America And West Africa, A. Mel Cosentino, Sue Fisher

Anthropogenics and Population Decline Collection

Aquatic bushmeat can be defined as the products derived from wild aquatic megafauna (e.g., marine mammals) that are used for human consumption and non-food purposes, including traditional medicine. It is obtained through illegal or unregulated hunts as well as from stranded (dead or alive) and bycaught animals. In most South American and West African countries aquatic mammals are or have been taken for bushmeat, including 33 small cetaceans and all three manatee species. Of these, two cetacean species are listed in the IUCN red list as “near threatened,” and one as “vulnerable,” as are all manatee species. Additionally, 22 cetacean …
