Matrix Model Analysis Of A Coastal Northern California Subpopulation Of The Western Snowy Plover (Charadrius Alexandrinus Nivosus), Jaclyn Grace Stewart 2017 Claremont McKenna College

Matrix Model Analysis Of A Coastal Northern California Subpopulation Of The Western Snowy Plover (Charadrius Alexandrinus Nivosus), Jaclyn Grace Stewart

CMC Senior Theses

Shorebirds are increasingly threatened by introduced predators, invasive grasses, and human disturbance. Matrix models can be used to predict population growth and assess management options. The Pacific coast population of the western snowy plover, Charadrius alexandrinus nivosus, is listed as threatened under the Endangered Species Act, largely due to high rates of nest predation. A matrix model for the entire Pacific coast metapopulation of western snowy plovers was published in 1999 by Nur et al., but population growth has not been comprehensively reassessed since, even after development of a recovery plan (USFWS 2007) and extensive management intervention. I built and ...


Sandhill And Whooping Cranes, Jeb Barzen, Ken Ballinger 2017 Private Lands Conservation, LLC

Sandhill And Whooping Cranes, Jeb Barzen, Ken Ballinger

Wildlife Damage Management Technical Series

As sandhill crane populations continue to grow in the United States, so too does crop damage, property damage to homeowners, and the risk of crane collisions with aircraft. Whooping crane populations also continue to grow, but with a global population of about 500 individuals (as of 2017), damage is rare and problems often require different solutions due to the species’ endangered status. The behavioral characteristics and habitat needs of sandhill and whooping cranes set the stage for conflict between these birds and people. Recognizing behavioral differences between territorial and non-territorial cranes greatly improves the effectiveness of any management effort.

An Analysis Of Morphometric Differentiation In Lake And River Populations Of The Emerald Shiner, Notropis Atherinoides, John J.V. Lang 2016 Buffalo State College

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 ...


Evolution In Light Of Mitonuclear Landscapes An Examination Of Mitochondrial Replacement In Killifish (Fundulus Spp.), Stephen D. Flanagan 2016 University of Southern Mississippi

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. Within the ...


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 2016 Universidade do Estado do Rio de Janeiro

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

Faculty Publications from the Harold W. Manter Laboratory of Parasitology

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 ...


Monk Parakeets, Michael L. Avery, James R. Lindsay 2016 National Wildlife Research Center

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 has ...


Understanding The Impact Of Commercial Harvest On White Suckers (Catostomus Commersonii) In Maine, Megan A. Begley 2016 University of Maine - Main

Understanding The Impact Of Commercial Harvest On White Suckers (Catostomus Commersonii) In Maine, Megan A. Begley

Electronic Theses and Dissertations

The State of Maine issues an unlimited number of commercial permits for the harvest of White Suckers Catostomus commersonii in Maine’s inland waters. The fishery provides a necessary source of fresh lobster Homarus americanus bait to coastal communities at a time when other bait sources are scarce. The impacts of the increasing number of permits and subsequent numbers of fishermen on the white sucker population is unknown. The Maine Department on Inland Fisheries and Wildlife (MDIFW) has closed a number of waters due to concerns that overfishing and incidental catch of other fish species may occur.

Parajulid Milliped Studies Xi: Initial Assessment Of The Tribe Gosiulini (Diplopoda: Julida), Rowland M. Shelley, Jamie M. Smith 2016 University of Tennessee, Knoxville

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 of ...

Reproductive Schedule Of The Silver Shiner (Notropis Photogenis) In The Flint River Of Alabama, Kelly Hodgskins, Stephanie Greenleaf, Jonathan Hillman, Bruce Stallsmith 2016 University of Alabama in Huntsville

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 2016 California Polytechnic State University - San Luis Obispo

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 (STEM Teacher and Researcher) 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 ...


Cedar Waxwings, Michael L. Avery, Anthony G. Duffiney 2016 USDA National Wildlife Research Center

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 ...
