The aims of the original proposed project remain the same, that is, to test the hypothesis that Managed Aquifer Recharge (MAR) for stormwater harvesting is a technically feasible, socially and environmentally acceptable, economically viable, and legally feasible option for developing new water supplies for arid Western urban ecosystems experiencing increasing population, and climate change pressures on existing water resources. The project is being carried out via three distinct but integrated components that include: 1) Monitoring of existing distributed MAR harvesting schemes involving a growing number of demonstration Green Infrastructure (GI) test sites; 2) Integrated stormwater/vadose zone/groundwater/ ecosystem services modeling; and …
Investigation Of Seed And Seedling Predation And Natural History Of Bushveld Savanna Rodents, Christopher Banotai
Investigation Of Seed And Seedling Predation And Natural History Of Bushveld Savanna Rodents, Christopher Banotai
Masters Theses & Specialist Projects
There is currently a decline in large, old trees within many ecosystems where they play important ecological and economic roles. One ecosystem suffering from this decline is the bushveld savanna of South Africa. One particularly important species in decline is the ecologically, economically, and culturally significant marula tree (Sclerocarya birrea subsp. caffra). This species’ decline is characterized by a steep drop in recruitment of seedlings into the population. Rodents are known to influence plant communities across many ecosystems through herbivory of adult plants as well as predation of seeds and seedlings. This research provides a record of rodent species present …
There’S More Than One Way To Climb A Tree: Limb Length And Microhabitat Use In Lizards With Toe Pads, Travis J. Hagey, Scott Hart, Matthew Vickers, Luke J. Harmon, Lin Schwarzkopf
There’S More Than One Way To Climb A Tree: Limb Length And Microhabitat Use In Lizards With Toe Pads, Travis J. Hagey, Scott Hart, Matthew Vickers, Luke J. Harmon, Lin Schwarzkopf
Biology
Ecomorphology links microhabitat and morphology. By comparing ecomorphological associations across clades, we can investigate the extent to which evolution can produce similar solutions in response to similar challenges. While Anolis lizards represent a well-studied example of repeated convergent evolution, very few studies have investigated the ecomorphology of geckos. Similar to anoles, gekkonid lizards have independently evolved adhesive toe pads and many species are scansorial. We quantified gecko and anole limb length and microhabitat use, finding that geckos tend to have shorter limbs than anoles. Combining these measurements with microhabitat observations of geckos in Queensland, Australia, we observed geckos using similar …
A Multi-Indicator Assessment Of Conservation Success Across A Populated Forest Anthrome, Emma Cook, Natalie Ribble, John Quinn
A Multi-Indicator Assessment Of Conservation Success Across A Populated Forest Anthrome, Emma Cook, Natalie Ribble, John Quinn
Biology Presentations
The heterogeneous landscape of the eastern United States has resulted in a diversity of conservation interventions including public protected areas, private lands held in easements, and open space managed at various levels of intensity. Given the pressures of expected land use and land cover change, particularly in the Southern Piedmont ecoregion, multi-scale and comprehensive data are needed to prioritize conservation actions. We assessed local and regional indicators of conservation success across an urban-rural gradient by analyzing local bird abundance and diversity as a factor of forest patch area, land use matrix, and land management strategy. The study was conducted across …

Creative Nonnatives: Painting Invasive Insects Of The United States, Monica Tynan
Creative Nonnatives: Painting Invasive Insects Of The United States, Monica Tynan
Senior Honors Projects
An invasive species is a nonnative organism that may cause damage to an ecosystem. Invasive species cause problems in an environment by outcompeting native organisms for resources or by feeding upon native species. Invasive insects in particular can harm an ecosystem by consuming foliage and decreasing biodiversity. During my experience at the Preisser Lab at the University of Rhode Island, I witnessed rsthand the damage that invasive insects can do to a tree population, and I learned about how ecosystem dynamics can be disrupted by the introduction of a nonnative species.
My project portrays an aesthetically pleasing visualization of several …

Perception Of The Horizon Predicts Bird Abundance Better Than Habitat Patch Size In A Tidal Marsh Species Of Conservation Concern, Hallie Marshall
Perception Of The Horizon Predicts Bird Abundance Better Than Habitat Patch Size In A Tidal Marsh Species Of Conservation Concern, Hallie Marshall
Honors College
The Saltmarsh Sparrow (Ammodramus caudacutus) is a tidal marsh bird species facing rapid population decline throughout its range. A major cause of this decline is degradation and loss of breeding habitat, and thus there is a need to preserve coastal marshes in the northeastern United States. To do so requires an understanding of the habitat features that support robust populations. Previous studies have shown increases in Saltmarsh Sparrow abundance with marsh size increases. In other grassland bird species, habitat patches with low horizons are preferred to those with tall objects (e.g., trees, telephone poles, wind turbines). This study tests how …

Hearing On The Fly: The Effects Of Wing Position On Noctuid Moth Hearing, Shira D. Gordon, Elizabeth Klenschi, James F. C. Windmill
Hearing On The Fly: The Effects Of Wing Position On Noctuid Moth Hearing, Shira D. Gordon, Elizabeth Klenschi, James F. C. Windmill
Dartmouth Scholarship
The ear of the noctuid moth has only two auditory neurons, A1 and A2, which function in detecting predatory bats. However, the noctuid's ears are located on the thorax behind the wings. Therefore, as these moths need to hear during flight, it was hypothesized that wing position may affect their hearing. The wing was fixed in three different positions: up, flat and down. An additional subset of animals was measured with freely moving wings. In order to negate any possible acoustic shadowing or diffractive effects, all wings were snipped, leaving the proximal-most portion and the wing hinge intact. Results revealed …
Examining Movement And Habitat Selection Of Everglades Fishes In Response To Seasonal Water Levels, Gregory J. Hill
Examining Movement And Habitat Selection Of Everglades Fishes In Response To Seasonal Water Levels, Gregory J. Hill
FIU Electronic Theses and Dissertations
Fish distribution patterns and seasonal habitat use play a key role in the food web dynamics of aquatic ecosystems, including the Florida Everglades. In this study I examined the fine scale habitat shifts and movements of spotted sunfish, Lepomis punctatus across varying seasons and hydrologic conditions using in-situ field enclosures and Passive Integrated Transponder (PIT) systems. Data on fish use of three dominant Everglades marsh habitats and activity level were recorded continuously from January to August, 2015. Fish were more active and had the highest use of higher elevation habitats when water levels rose during an experimental reversal in mid-April. …
Climate Dynamics, Invader Fitness, And Ecosystem Resistance In An Invasion-Factor Framework, Stephen L. Young, David R. Clements, Antonio Ditommaso
Climate Dynamics, Invader Fitness, And Ecosystem Resistance In An Invasion-Factor Framework, Stephen L. Young, David R. Clements, Antonio Ditommaso
West Central Research and Extension Center, North Platte
As researchers and land managers increasingly seek to understand plant invasions and the external (climate) and internal (plant genetics) conditions that govern the process, new insight is helping to answer the elusive question of what makes some invasions successful and others not. Plant invasion success or failure is based on a combination of evolutionary and ecological processes. Abiotic (e.g., climate) and biotic (e.g., plant competition) conditions in the environment and plant genetics (e.g., fitness) combine in either decreasing or increasing invasion, yet it has proven challenging to know exactly which of these conditions leads to success for a given species, …
The Effect Of Beaver Dams On Macroinvertebrate Communities, Anna Shampain
The Effect Of Beaver Dams On Macroinvertebrate Communities, Anna Shampain
Summer Research
Impacts of habitat alterations caused by beaver presence on the composition and disturbance tolerance of local macroinvertebrate communities were studied. Beavers act as ecosystem engineers by altering water flow, temperature, nutrient, organic carbon and groundwater storage, and by increasing the overall geomorphic complexity of river systems through dam construction. Macroinvertebrates are widespread across freshwater habitats, they act as primary processers of organic materials serve as a food source for various freshwater species. Samples of macroinvertebrate communities were collected in the streams within the Methow River Watershed in North-Central Washington. Streams with known beaver presence (n= 4) and without beaver activity …

The Philosophers' Paul For Earthlings: Stanislas Breton And The Ecological Significance Of The Way Of The Cross., Justin Klassen
Theology Faculty Publications and Presentations
Christian eco-theology, a maturing subfield in the area of religion and ecology, was born as a response to the historian Lynn White, Jr.'s suggestion that "we shall continue to have a worsening ecological crisis until we reject the Christian axiom that nature has no reason for existence save to serve man." Whether this claim is in fact axiomatic for Christianity is certainly debatable; nonetheless, many eco-theologians today agree that White was onto something.
Effects Of Habitat Restoration On Soil Retention On Santa Rosa Island, Michael Perez, Kathryn Mceachern, Ken Niessen
Effects Of Habitat Restoration On Soil Retention On Santa Rosa Island, Michael Perez, Kathryn Mceachern, Ken Niessen
STAR Program Research Presentations
Ranching began on Santa Rosa Island in the 1840’s, consequently introducing nonnative megafauna that put novel selective grazing pressures on endemic plant species. Their movement patterns also altered substrate integrity as the land became denuded of any stabilizing vegetation. Dense groves of island oak (Q. tomentella) are known to aid in sediment deposition and retention. The groves also function to collect water during periods of intense fog common to the island. This experiment sought to determine whether sediment is being lost or deposited on a ridge in the middle of the island containing a grove of Q. tomentella …

Crassulacean Acid Metabolism As A Continuous Trait: Variability In The Contribution Of Crassulacean Acid Metabolism (Cam) In Populations Of Portulacaria Afra, Lonnie J. Guralnick, Kate Gladsky
Arts & Sciences Faculty Publications
Portulacaria afra L. is a dominant facultative CAM species growing in the Southeastern Cape of South Africa. P. afra is well adapted to regions of the Spekboom thicket in areas of limited and sporadic rainfall. P. afra populations occur in isolated drainages. We hypothesized the utilization of CAM would vary in the different populations in response to rainfall and temperature gradients. Carbon isotope composition can be used to determine the contribution of CAM in leaf tissue. P. afra leaves of populations were analyzed in transects running south to north and east to west in locations from the coast to elevations …
