A Glimpse Into The Ecological Communities Of Camp Greenwood, Rachael Noteboom Nov 2018

A Glimpse Into The Ecological Communities Of Camp Greenwood, Rachael Noteboom

Honors Projects

There is a Presbyterian summer camp near Greenville, Michigan that is home to beautiful wetlands with a variety of wildlife. This camp is nestled between multiple larger connected lakes and surrounded by many large waterfront properties. The number of campers has dwindled in recent years and the council in charge of the land is desperate to sell the most ecologically important sections of the camp, if not all of the land, to developers for multi-million dollar price tags. My dad is on the committee trying to convince the council and the community to save the camp from development.

I surveyed …


Impacts Of Natural And Anthropogenic Colonized Habitats On The Range Shifting Mangrove Tree Crab (Aratus Pisonii), Zachary John Cannizzo Oct 2018

Impacts Of Natural And Anthropogenic Colonized Habitats On The Range Shifting Mangrove Tree Crab (Aratus Pisonii), Zachary John Cannizzo

Theses and Dissertations

Mis-matches in climate-mediated shifting rates cause the ranges of some species to become decoupled from their historic ecosystem, leading to the colonization of ecosystems they have not previously inhabited. When this occurs, the shifting species may experience suboptimal conditions which challenge its ability to persist and expand into the novel ecosystem. However, within the colonized ecosystem, shifting species may encounter artificial habitat analogues: artificial habitats that more closely resemble the species’ historic ecosystem than the surrounding habitat and which mitigate some of the negative impacts experienced elsewhere in the novel ecosystem. Despite their importance to the ecology, life history, and …

Confirming World-Wide Distribution Of An Agriculturally Important Lacewing, Chrysoperla Zastrowi Sillemi, Using Songs, Morphology, Mitochondrial Gene Sequencing, And Phylogenetic Reconstruction, Zoe Mandese Aug 2018

Confirming World-Wide Distribution Of An Agriculturally Important Lacewing, Chrysoperla Zastrowi Sillemi, Using Songs, Morphology, Mitochondrial Gene Sequencing, And Phylogenetic Reconstruction, Zoe Mandese

Honors Scholar Theses

The Chrysoperla carnea-group of green lacewings is a cryptic species complex. Species within the group are morphologically similar, yet isolated from one another via reproductive mating song. Chrysoperla zastrowi, a species within the carnea-group, is currently described with a distribution ranging from South Africa to the Middle East and India. However, recent collections of carnea-group lacewings from Guatemala and California were preliminarily identified as Chrysoperla zastrowi based upon similarities in their vibrational courtship songs. This analysis aims to place six specimens, collected by collaborators in Guatemala, Armenia, Iran, and California, into a pre-existing phylogeny of the …

The Population Ecology And Behavior Of The Cave Salamander, Eurycea Lucifuga (Rafinesque, 1822)., Joseph Gavin Bradley Aug 2018

The Population Ecology And Behavior Of The Cave Salamander, Eurycea Lucifuga (Rafinesque, 1822)., Joseph Gavin Bradley

Electronic Theses and Dissertations

The Cave Salamander, Eurycea lucifuga (Rafinesque, 1822), is a little-known species, yet a common inhabitant of caves in the eastern United States. Salamanders are often important components of ecological communities and ecosystems, influencing critical processes such as nutrient cycling and community composition through their predation on invertebrates. Cave-dwelling salamanders such as E. lucifuga may thus appreciably influence the relatively simple ecosystems and communities of caves. Any such influence may be particularly important because these habitats and the organisms that reside in them are often of conservation concern. I used non-invasive methods to study the demographics, movements, and habitat selection of …


Opportunities To Enhance Environmental Flows On The Rio Chama, Anjali Bean Aug 2018

Opportunities To Enhance Environmental Flows On The Rio Chama, Anjali Bean

Water Resources Professional Project Reports

The construction of El Vado dam on the Rio Chama in 1935 dramatically changed the natural flow of the river, reducing spring runoff and summer scouring floods in favor of providing a constant water supply to downstream users. The San Juan-Chama Project, a trans-basin water diversion built as part of the Colorado River Compact, also significantly increased water flow in the river, a unique situation in the state of New Mexico. This increase in management of the river for human benefit has permanently altered the natural hydrograph of the river and the ecology and geomorphology of the system that depends …


Woodpeckers In The City: Habitat Use And Minimum Area Requirements Of Woodpeckers In Urban Parks And Natural Areas In Portland, Oregon, Adam Baz Jun 2018

Woodpeckers In The City: Habitat Use And Minimum Area Requirements Of Woodpeckers In Urban Parks And Natural Areas In Portland, Oregon, Adam Baz

Dissertations and Theses

Urbanization has contributed to the fragmentation and alteration of natural habitats around the globe, and is rapidly increasing. In this context, forested parks play a critical role for many species by providing patches of usable habitat within the urban matrix. Such patches may be particularly valuable to forest-specialists like woodpeckers (Picidae). Yet many woodpeckers require large forest patches, which are limited in fragmented landscapes. Despite their recognized value as ecosystem engineers and keystone species, almost no research exists on woodpecker ecology or space-use in urban settings. What habitat components influence woodpecker abundance and what are their functional minimum area requirements …

Feeding Patterns Of Two Commercially Important Fish Species Scomberoides Commersonnianus And S. Tol In The Northern Arabian Sea Coast Of Pakistan, Nazia Qamar, Sher Khan Panhwar, Ralf Riedel

Faculty Publications

Port landing of Scomberoides commersonnianus and S. tol were obtained between July 2013 and June 2015 for stomach content analysis. Analysis of prey composition was done using permutational analysis of variance (permanova), with species, life stage (juvenile and adults), gender, and weather (rainy and dry season) as factors. Patterns of empty stomachs were investigated to estimate feeding intensity. Feeding intensity was estimated with logistic regression, using the same independent variables as above. Prey importance was also investigated. Prey importance was assessed using a Wilcox Rank Correlation analysis on the Index of Relative Importance (IRI) by species and life-stage. Permanova analysis …

A Quantitative Analysis Of The Effects Of Urbanization, Mesophication And Prescribed Burns On Oak Woodlands In The Chicago Metropolitan Area, Chad Populorum May 2018

A Quantitative Analysis Of The Effects Of Urbanization, Mesophication And Prescribed Burns On Oak Woodlands In The Chicago Metropolitan Area, Chad Populorum

Celebration of Learning

Urban expansion has had devastating impacts on forest ecosystems, especially within the past century. Human attempts to dominate nature have diminished natural disturbance regimes, which have maintained the biodiversity and historic composition of these ecosystems. Fires have been a prominent force in maintaining the structure of oak, hickory and other heliophytic (sun loving and fire-adapted) forest systems. Human induced fire suppression has led to mesophication across North America. Mesophication is the transition from drier conditions with open canopies to wetter conditions with closed canopies. These new conditions decrease the survival rates of these important species and begin to favor mesophytic …


The Effects Of Gopher Tortoise (Gopherus Polyphemus) Herbivory On Plant Community Composition And Seed Germination, And The Effects Of Gut Passage On The Germinability Of Seeds: A Meta-Analysis, Jason C. Richardson May 2018

The Effects Of Gopher Tortoise (Gopherus Polyphemus) Herbivory On Plant Community Composition And Seed Germination, And The Effects Of Gut Passage On The Germinability Of Seeds: A Meta-Analysis, Jason C. Richardson

USF Tampa Graduate Theses and Dissertations

Herbivory produces direct and indirect effects on plants and at different spatial scales will have varied consequences. Consumption of plants by vertebrate grazers may affect the plants on an organismal level through direct mortality, on a community level by changing species composition or by altering the rate of succession, and even at a whole ecosystem level by altering nutrient cycles.

The majority of the scientific literature has focused extensively on herbivory by mammals and birds. With regard to mammals, studies have shown how folivory affects individual plants, plant populations, and communities of plants.

Mammals, as well as birds, also ingest …

Modified Landscapes, Esther Nooner May 2018

Modified Landscapes, Esther Nooner

Graduate Theses and Dissertations

Modified Landscapes is a body of work that reflects serious thought regarding Nature and its future. My personal experience and beliefs are at the core of why I believe this subject to be of great importance and why it will sustain many artists’ investigations for the time to come. The influences that informed this process are explored through experiences I had traveling, reading and exploring the photograph as a material object. The manipulation of the photograph is meant to question the beautiful, untouched scene and break the Romantic gaze that is historically tied to representations of Nature and insist upon …
