Lepidopteran Granivory Reduces Seed Counts In A Rare Species Of Riparian Scour Prairies, Cheyenne Moore, Angela J. Mcdonnell, Scott Schuette, Christopher T. Martine
Lepidopteran Granivory Reduces Seed Counts In A Rare Species Of Riparian Scour Prairies, Cheyenne Moore, Angela J. Mcdonnell, Scott Schuette, Christopher T. Martine

In Pennsylvania Baptisia australis var. australis is found along only four waterways: the Allegheny River, Youghiogheny River, Clarion River, and Red Bank Creek. Because of its limited distribution and small number of extant populations, the species is considered state-threatened in Pennsylvania. In addition, the riparian prairie habitat that Pennsylvania Baptisia australis var. australis is restricted to is also in decline and considered vulnerable. Because of these conservation concerns, insights into the natural history of the taxon in the state is valuable and will inform conservation efforts. Field surveys and fruit collections along the Allegheny River and herbarium collections were used …
Investigation Into The Genetic Provenance Of Three Rare Plants With East-West Disjunction Patterns In Pennsylvania., Scott Schuette, Christopher T. Martine
Investigation Into The Genetic Provenance Of Three Rare Plants With East-West Disjunction Patterns In Pennsylvania., Scott Schuette, Christopher T. Martine
Other Faculty Research and Publications
Rare plant conservation relies on an understanding of the natural history, biology and ecology, and real and potential threats to their populations to inform state regulations that serve to protect the species from extirpation. This work often involves extensive field surveys over several years to determine population sizes and whether those populations are seeing reductions in number of individuals necessary to maintain the genetic diversity within and between those populations. Species and populations with high genetic diversity are better equipped to withstand sudden changes to their habitats that derive from land use changes and changing climate. There are a variety …
Everyone In: A Road Map For Science-Based, Collaborative Restoration Of Western Quaking Aspen, Sue Miller
Everyone In: A Road Map For Science-Based, Collaborative Restoration Of Western Quaking Aspen, Sue Miller
Aspen Bibliography
With concern over the health of aspen in the Intermountain West, public and private land managers need better guidance for evaluating aspen condition and selecting and implementing actions that will be effective in restoring aspen health. The Utah Forest Restoration Group collaboratively synthesized a step-by-step approach for aspen restoration that was applicable to western U.S. forests. In a successful case study in shared stewardship, these restoration guidelines were applied to a challenging real-world setting.The Monroe Mountain Aspen Ecosystem Restoration Project, addressed diverse public and private lands needs and interests using an “All Hands, All Lands” strategy. The Monroe Mountain Working …

Cuba is an ecological rarity in Latin America and the Caribbean. Its complex political and economic history shows limited disturbances, extinctions, pollution, and resource depletion by legal or de facto measures. Vast mangroves, wetlands, and forests play key roles in protecting biodiversity and reducing risks of hazards caused or aggravated by climate change. Cuba boasts coral reefs with some of the region’s greatest fish biomass and coral cover. Although Cuba has set aside major protected areas that safeguard a host of endemic species, its environment is by no means pristine. Its early history is one of deforestation and agricultural production …
Historic Distribution And Ecology Of Tall-Grass Prairie In Western Canada, Darcy C. Henderson, Nicola Koper
Historic Distribution And Ecology Of Tall-Grass Prairie In Western Canada, Darcy C. Henderson, Nicola Koper
The Prairie Naturalist
Rapid settlement and agricultural development of western Canada in the late 1800s and early 1900s nearly eliminated the tall-grass prairie, and pre-empted a detailed description by ecologists. A combination of literature review and historical ecological analysis of soils, climate, and composition data are applied to estimate the historic distribution, and area occupied by tall-grass prairie in southern Manitoba and southeastern Saskatchewan, Canada. The resulting area estimate of 20,830 km2 is more than three times any previously reported value. Some confusion of terms from the first half of the 1900s, and the impact of invasive species on vegetation patterns observed …
Genetic Structure Of The Florida Key Tree Cactus, Pilosocereus Robinii, Using Restriction Site Associated Dna (Rad) Markers, Tonya D. Fotinos
Genetic Structure Of The Florida Key Tree Cactus, Pilosocereus Robinii, Using Restriction Site Associated Dna (Rad) Markers, Tonya D. Fotinos
FIU Electronic Theses and Dissertations
Rare plant conservation efforts must utilize current genetic methods to ensure the evolutionary potential of populations is preserved. One such effort involves the Key Tree Cactus, Pilosocereus robinii, which is an endangered columnar cactus native to the Florida Keys. The populations have precipitously declined over the past decade because of habitat loss and increasing soil salinity from rising sea levels and storm surge. Next-generation DNA sequencing was used to assess the genetic structure of the populations. Twenty individuals representative of both wild and extirpated cacti were chosen for Restriction Site Associated DNA (RAD) analysis. Samples processed using the HindIII …
Burrowing Owl Associations With Black-Tailed Prairie Dog Colonies In Southwestern Kansas And Southeastern Colorado, Stephen L. Winter, Jack F. Cully Jr.
Burrowing Owl Associations With Black-Tailed Prairie Dog Colonies In Southwestern Kansas And Southeastern Colorado, Stephen L. Winter, Jack F. Cully Jr.
The Prairie Naturalist
We quantified the use of black-tailed prairie dog (Cynomys ludovicianus) colonies as habitat for the burrowing owl (Athene cunicularia) in southwestern Kansas and southeastern Colorado. We used incidental sightings and breeding season avifauna surveys to document the presence of the burrowing owl on black-tailed prairie dog colonies, non-colonized rangeland, and cropland during the spring and early summer. Burrowing owl rarely was observed on noncolonized rangeland and cropland sites, and black-tailed prairie dog colonies appear to be used substantially as a habitat type for the burrowing owl in the region encompassing Cimarron and Commanche National Grasslands in …
Vascular Flora Of Van Horn Woods, Plainfield Township, Will County, Il, Joseph Traina
Vascular Flora Of Van Horn Woods, Plainfield Township, Will County, Il, Joseph Traina
Faculty Publications & Research
The vascular flora at Van Horn Woods Park was surveyed during the 1998-2000 growing seasons. This park is a 30 hectare site located in Plainfield Township, Will County, Illi- nois (SE1/4 S27 T36N R9E). A total of 246 taxa, representing 160 genera and 67 fami- lies, were identified within or immediately adjacent to the park. Seventy-one percent of these taxa were native. Four taxa were collected and submitted to the Morton Arboretum as new county records for Will County. The quality of this site as a natural area was also assessed using quantitative methods based on floral composition and diversity. …
