Ecotourism As A Means Of Sustaining Livelihood, Wildlife Management And Biodiversity Conservation-A Case In Nameri National Park Of Assam: India, Niranjan Das

IGC Proceedings (1977-2023)

Community-based Ecotourism (CBET) is an emerging concept. It is being discussed as an important tool for economically benefiting communities that have a feature that fulfils a tourist’s desire for uniqueness. Ecotourism is potentially important for communities reside nearby protected areas. Here, an attempt has been made to evaluate ecotourism initiatives in Nameri National Park, steps that have been introduced by the Assam (Bhorelli) Angling and Conservation Association (ABACA). This association began naturebased tourism ventures in 1956, bringing benefits to the local populace in terms of income, improved infrastructure, employment opportunities and exposure. The community’s capacity to facilitate resourcerelated conflicts has …

Tree Legumes As Sustainable Ecosystem Services In Livestock Systems, James P. Muir, C. E. Cooper, V. Corriher-Olson

IGC Proceedings (1977-2023)

Arboreal legumes provide multiple uses in pastures and rangelands. Trees directly and indirectly feed, house, doctor, and warm humans at minimal environmental cost through forage (fodder), timber, biofuel, medicines, as well as edible leaves, pods, and seeds. Leguminous trees, because they foster biological nitrogen fixation (BNF) and acquire deep-soil nutrients and moisture, compete less with herbaceous plants for shallow-horizon soil moisture and nutrients. Their ecosystem services (ES) are generally less obvious and quantifiable. These include converting CO₂ to sequestered C and released O₂ in N-poor soils where trees without BNF do not thrive. Other ES include shade for …

Conservation Innovation In Pastoral Lands Around The Globe: Challenges, Lessons And Opportunities, R. S. Reid

IGC Proceedings (1977-2023)

Pastoralists and ranchers have a long history of sustained management of rangelands around the world. Several decades ago, some pastoralists and ranchers started new alliances with environmental organizations, businesses and government agencies to diversify their approaches to land management to include what can be called ‘conservation’. These efforts highlight conserving aspects of rangeland ecosystems, but often have an equal or greater emphasis on supporting pastoral livelihoods and culture. This paper asks: What types of innovations are pastoralists now pursuing in ‘conservation’? How are these innovations performing?

This paper provides a synthesis of some of the types of conservation innovations being …

The Importance Of Forage Legume Inclusion In Agricultural Swards To Enhance Earthworm Activity And Water Infiltration Rates, A. Shnel, S. Tracy, O. Schmidt, P. Murphy, M. B. Lynch, C. Grace, T. M. Boland, H. Sheridan

IGC Proceedings (1977-2023)

Increased grassland productivity in temperate regions has largely been achieved through perennial ryegrass Lolium perenne (PRG), coupled with large quantities of nitrogen fertiliser. However, concern is growing regarding the negative implications of excessive dependence on nitrogen fertilisers. Research has demonstrated the benefits of legume inclusion on primary productivity, however, their potential to influence other processes is less well established.

Sampling was undertaken in autumn 2017 on twenty randomised plots representing five sward types, replicated four times. These had been established and managed by cutting since 2013. Sward types included: 1) PRG (250kg N ha^-1 yr^-1 ); 2) PRG; …

Winston Churchill On The American Constitution, Gerard N. Magliocca

St. John's Law Review

(Excerpt)

Though best known for leading Britain during World War II, Winston Churchill was a keen observer of constitutional law. Most of his insights concerned the unwritten conventions of the British Constitution, but Churchill also commented extensively on the American Constitution. Intellectual curiosity and a desire to forge a closer alliance between Great Britain and the United States were at the root of Churchill’s interest in the institutions of what he called “The Great Republic.” As with all things Churchill, his observations on our Constitution were sometimes inspiring, sometimes illuminating, and sometimes noxious.

Investigating The Effect Of Community-Based Educational Robotics Programs On Underrepresented Youth, Eric Flaningam, Hanna Keyerleber, Christopher Embry

Purdue Journal of Service-Learning and International Engagement

Traditional STEM academic programs have a large discrepancy in participation and engagement between low-income and minority students as compared to their peers from other demographics. This underrepresentation is visible beginning in the classroom and carrying through to higher education and the STEM workforce. The Ware Research Group previously studied the STEM learning environments of low-income communities in Lafayette, IN. Study results suggested that traditionally structured classroom environments were not effective in achieving high levels of participation and engagement in STEM material. To address this deficit, the research group is observing how community-centered STEM programs affect participation and engagement from low-income …

The Response Of Selected Temperate Forages To Increasing Summer Drought Conditions And High Summer Temperatures In Northern Victoria, Australia, M. E. Rogers, A. R. Lawson, K. B. Kelly, W. J. Wales, J. L. Jacobs

IGC Proceedings (1977-2023)

In the dairy region of northern Victoria, Australia, the performance of temperate perennial dairy pastures is often poor over summer due to a combination of high temperatures and limited water availability that can restrict dry matter production and plant survival. A series of field experiments examined the effects of heat and restricted irrigation (as a consequence of drought) on the growth and nutritive characteristics of selected forage species, and whether survival under experimental conditions was influenced by plant genotype, irrigation and grazing management strategies, as well as endophyte presence. The major focus was on perennial ryegrass.

Soil Organic Carbon And Total Nitrogen In A Leucaena Leucocephala Silvopastoral System In The Chaco Region, Argentina, N. R. Banegas, N. Viruel, A. Radrizzani

IGC Proceedings (1977-2023)

The introduction of leucaena (Leucaena leucocephala) into hedgerow silvopastoral systems increases animal production and improves soil fertility, through biological nitrogen fixation and deep-rooted leguminous trees. There is limited information on carbon and nitrogen dynamics in hedgerow silvopastoral systems, particularly in long term periods and subsoil profiles. The concentrations and vertical distribution of organic carbon (OC) and total nitrogen (TN), and their fractions (particulate and associate forms) in the soil profile (0‒100 cm), with and without leucaena were compared 10 years after leucaena establishment into a 24-year-old tropical pasture (Urochloa brizantha-Chloris gayana). Leucaena increased the OC concentration …

Fite, Landys Z. Guo, Danielle K. J. Henry, Alana K. Kaffenberger, Katherine S. Manning, Tatum E. Mowery, Cecilia L. Pankau, Nyla Parker, Malina E. Serrano, Yamaan Shakhashiro, Hannah N. Tanner, Ruth. A. Ward, Aubrey H. Wehry, Robin L. Cooper

Biology Faculty Publications

Proprioception of all animals is important in being able to have coordinated locomotion. Stretch activated ion channels (SACs) transduce the mechanical force into electrical signals in the proprioceptive sensory endings. The types of SACs vary among sensory neurons in animals as defined by pharmacological, physiological and molecular identification. The chordotonal organs within insects and crustaceans offer a unique ability to investigate proprioceptive function. The effects of the extracellular environment on neuronal activity, as well as the function of associated SACs are easily accessible and viable in minimal saline for ease in experimentation. The effect of extracellular [Ca²⁺] on …

The Effect Of Optogenetically Activating Glia On Neuronal Function, Cecilia Pankau, Shelby Mccubbin, Robin L. Cooper

Biology Faculty Publications

Glia, or glial cells, are considered a vital component of the nervous system, serving as an electrical insulator and a protective barrier from the interstitial (extracellular) media. Certain glial cells (i.e., astrocytes, microglia, and oligodendrocytes) within the CNS have been shown to directly affect neural functions, but these properties are challenging to study due to the difficulty involved with selectively-activating specific glia. To overcome this hurdle, we selectively expressed light-sensitive ion channels (i.e., channel rhodopsin, ChR2-XXL) in glia of larvae and adult Drosophila melanogaster. Upon activation of ChR2, both adults and larvae showed a rapid contracture of body wall …

Associations Of Diet With Cardiometabolic And Inflammatory Profiles In Pregnant Women At Risk For Metabolic Complications, Kataryna Jaworsky, Jeffrey L. Ebersole, Petar Planinic, Arpita Basu

Dental Medicine Faculty Research

Dietary intakes play an important role in the development of metabolic complications during pregnancy. While reported observational studies reveal an inverse association of healthy diets with weight gain, gestational diabetes, and hypertensive complications during pregnancy, there is a paucity of studies conducted among women of specific ethnicities vulnerable to higher risks of pregnancy complications. This is a secondary cross sectional analysis using baseline data from a previously reported clinical trial. We aim to identify associations of maternal habitual dietary intakes with cardiometabolic risks and inflammatory profiles in primarily African American (AA) and Hispanic women in the first half of pregnancy. …

Microplastic In Agricultural Tile Drainage And Stream Water During Periods Of High And Low Flow, Laurel Grace Mcginnis

Theses and Dissertations

Microplastic accumulation is one of the greatest changes to every ecosystem on Earth. Microplastics, < 5 mm in diameter, are an emerging contaminant of concern and are found across every habitat. Microplastics are directly released into the environment from industrial and personal care products or are a result of degradation and fragmentation of larger plastic debris. Microplastic contamination in the natural environment can have negative chemical and ecological effects on aquatic biota and humans. Rivers are an important transport pathway of microplastics from terrestrial to marine ecosystems. There is very little data on the abundance of microplastics in freshwater. To better understand the magnitude of microplastic contamination in freshwater, the concentration of microplastic in agricultural drainage tile outlets and stream waters in McLean County, Illinois during Spring and Summer (high and low flow periods) were measured. Grab samples were collected from five tile and four stream sites across 4 watersheds. Microplastic concentrations at each site were compared using ArcGIS. Microplastics are present in both agricultural drainage tile outlets and agricultural streams during Spring and Summer with approximately 80% of the microplastic particles being fibers. We did find a significant difference in microplastic concentrations between Spring and Summer but no significant difference between tile and stream sites within seasons. Our results suggest tile outlets and the tiles themselves may be a significant source of microplastics to streams and may lead to substantial inputs to downstream systems like drinking water reservoirs. KEYWORDS: microplastic; contaminant; rivers; freshwater; agricultural drainage tile; drinking water reservoirs
