Harnessing The Four-Dimensional Ecology Education Framework To Redesign An Introductory Ecology Course In A Changing Higher Education Landscape, Nathan Ruhl, Patrick Crumrine, Jennifer Oberle, Courtney Richmond, Shelly Thomas, Sara Wright

School of Earth & Environment Departmental Research

As higher education undergoes rapid and fundamental change, eco-educators need to be prepared to promote the inclusion of the ecological sciences in the biological sciences curriculum of the future. Here, we present an instructional alignment for an introductory ecology course, which is informed by and integrated with the Four-Dimensional Ecology Education (4DEE) Framework. Our instructional alignment was created collaboratively among faculty involved in teaching the course and emphasizes the relevance and utility of the ecological sciences. We believe that this approach positions the ecological sciences for continued success and inclusion in the biological sciences curriculum of tomorrow.

Toxical Effect Of Euphorbia Guyoniana Aqueous Extracts (Euphorbiaceae) On Mortality, Larval Development And Sexual Behavior Of Drosophila Melanogaster (Diptera: Drosophilidae), Chabi Lila, Habbachi Wafa, Tahraoui Abdelkrim

Journal of Bioresource Management

Euphorbia guyoniana (Boiss and Reut) is a plant of Euphorbiaceae family common throughout the northern Sahara and pre-desert regions. In traditional medicine, they are used in the treatment of various infections. Euphorbiaceae contain various chemical compounds families such as alkaloids, which give them a toxic effect. The toxic effects of seeds decoctions on mortality and development of 3rd instar larvae of Drosophila melanogaster are studied. A treatment by ingestion shows a good larvicidal activity of this extract. It was shown that the chemical compounds contained in the extract, act on the fly development cycle as most of pupae do not …

Preliminary Survey And Diet Analysis Of Anurans In The Riparian Zone Of Calayagon Watershed, Agusan Del Norte, Philippines, Jenessa Verna B. Salo, Chennie L. Solania

Journal of Bioresource Management

Watersheds are critical habitats for a diverse array of organisms. Among all the fauna, anurans are excellent biological indicators of environmental health. The community structure is often associated with a relationship between species diversity and diet. An anuran survey was conducted along riparian zones of three selected barangays of Calayagon Watershed (Guinabsan, Rizal, and Malpoc), Philippines. Extensive opportunistic methods for a total of 480 man-hours were spent traversing the area. A total of 195 individuals, consisting of seven species from four families, were recorded. Seventy-two percent of the individual species were regarded as Least concern, and 14 % were Near-threatened. …

Temperature-Induced Multi-Species Cohort Effects In Sympatric Snakes, Richard B. King

Faculty Articles, Papers, and Other Scholarship

In reptiles, reproductive maturity is often determined by size rather than age. Consequently, growth early in life may influence population dynamics through effects on generation time and survival to reproduction. Because reproductive phenology and pre- and post-natal growth are temperature dependent, environmental conditions may induce multi-species cohort effects on body size in sympatric reptiles. I present evidence of this using 10 years of neonatal size data for three sympatric viviparous snakes, Dekay's Brown snakes (Storeria dekayi), Red-bellied Snakes (S. occipitomaculata), and Common Garter snakes (Thamnophis sirtalis). End-of-season neonatal size varied in parallel across species such that snout–vent length was 36%–61% …

Adultery and Fidelity in the Lais of Marie de France

Using both literary and historical analysis, I will examine contrasting depictions of adultery and fidelity within the lais written by 12th-century poet Marie de France. A lai is a type of narrative poem, ranging in length from 118 to 1184 lines. Many of Marie de France’s lais follow the literary trope known as courtly love; however, the reader is encouraged to sympathize with different characters depending on the lai. In some lais, the reader …

Optimizing Management Of Invasions In An Uncertain World Using Dynamic Spatial Models, Kim M. Pepin, Amy J. Davis, Rebecca S. Epanchin-Niell, Andrew M. Gormley, Joslin L. Moore, Timothy J. Smyser, H. Bradley Shaffer, William L. Kendall, Katriona Shea, Michael C. Runge, Sophie Mckee

United States Department of Agriculture Wildlife Services: Staff Publications

Dispersal drives invasion dynamics of nonnative species and pathogens. Applying knowledge of dispersal to optimize the management of invasions can mean the difference between a failed and a successful control program and dramatically improve the return on investment of control efforts. A common approach to identifying optimal management solutions for invasions is to optimize dynamic spatial models that incorporate dispersal. Optimizing these spatial models can be very challenging because the interaction of time, space, and uncertainty rapidly amplifies the number of dimensions being considered. Addressing such problems requires advances in and the integration of techniques from multiple fields, including ecology, …

An Efficient Method Of Evaluating Multiple Concurrent Management Actions On Invasive Populations, Amy J. Davis, Randy Farrar, Brad Jump, Parker Hall, Travis Guerrant, Kim M. Pepin

United States Department of Agriculture Wildlife Services: Staff Publications

Evaluating the efficacy of management actions to control invasive species is crucial for maintaining funding and to provide feedback for the continual improvement of management efforts. However, it is often difficult to assess the efficacy of control methods due to limited resources for monitoring. Managers may view effort on monitoring as effort taken away from performing management actions. We developed a method to estimate invasive species abundance, evaluate management effectiveness, and evaluate population growth over time from a combination of removal activities (e.g., trapping, ground shooting) using only data collected during removal efforts (method of removal, date, location, number of …

Sex-Related Differences In Aging Rate Are Associated With Sex Chromosome System In Amphibians, Hugo Cayuela, Beth Reinke, 48 Other Co-Authors

Biology Faculty Publications

Sex-related differences in mortality are widespread in the animal kingdom. Although studies have shown that sex determination systems might drive lifespan evolution, sex chromosome influence on aging rates have not been investigated so far, likely due to an apparent lack of demographic data from clades including both XY (with heterogametic males) and ZW (heterogametic females) systems. Taking advantage of a unique collection of capture–recapture datasets in amphibians, a vertebrate group where XY and ZW systems have repeatedly evolved over the past 200 million years, we examined whether sex heterogamy can predict sex differences in aging rates and lifespans. We showed …

Singing Strategies Are Linked To Perch Use On Foraging Territories In Heart-Nosed Bats, Grace C. Smarsh, Ashley M. Long, Michael Smotherman

Faculty Publications

Acoustic communication allows animals to coordinate and optimize resource utilization in space. Cardioderma cor, the heart-nosed bat, is one of the few species of bats known to sing during nighttime foraging. Previous research found that heart-nosed bats react aggressively to song playback, supporting the territorial defense hypothesis of singing in this species. We further investigated the territorial defense hypothesis from an ecological standpoint, which predicts that singing should be associated with exclusive areas containing a resource, by tracking 14 individuals nightly during the dry seasons in Tanzania. We quantified the singing behavior of individuals at all perches used throughout the …

Alfred Russel Wallace Notes 19: Social Evolution's Useful Idiots, Charles H. Smith

Faculty/Staff Personal Papers

In today’s world liberals look at conservatives as the villains, and vice versa. How did this come to pass? In this essay a model of the biological roots of liberalism and conservatism is advanced; this is followed by a discussion of why cognitive dissonance may represent the key process in our social evolution. Alfred Russel Wallace’s experience with cognitive dissonance is then detailed, including how he dealt with it.

Economics Of Cormorant Predation On Catfish Farms, Carole Engle, Ganesh Kumar, Terrel Christie, Brian S. Dorr, Brian Davis, Luke Roy, Anita Kelly

United States Department of Agriculture Wildlife Services: Staff Publications

The Double-crested Cormorant is the primary avian predator on catfish farms causing significant economic losses primarily due to 1) on-farm expenditures related to bird-management activities and 2) value of the catfish lost to cormorants. This comprehensive economic study quantified these two economic effects by surveying catfish farms in the delta regions of Mississippi and Arkansas. On-farm expenditures for bird scaring were used to quantify bird-management costs. Economic losses from fish consumed by cormorants were quantified by evaluating data from field studies of the abundance, distribution, and diet of cormorants in the Mississippi delta. This study found that catfish farmers …

Conservation, Comparative Genomics And Species Delimitation Of The Reindeer Lichens (Cladonia), Jordan R. Hoffman

Dissertations, Theses, and Capstone Projects

The genus Cladonia represents one of the most speciose genera of lichenized fungi, with more than 500 known species encompassing a diverse array of morphologies and habits. These lichens form keystone species in many habitats, serving a variety of ecological roles. However, despite being among of the more well studied lichens, there is much still unknown or under-studied about them. As is the case with most lichen study systems, phylogenetic study has been limited to a small number of partial loci, while adoption of next-generation sequence methods has been slow. As a consequence, there are still knowledge gaps in Cladonia …

Understanding Species Interactions And Their Impacts In Restored Communities, Jennifer Zhu

Dissertations, Theses, and Capstone Projects

Species interactions may mediate the ability of organisms to survive in a community and provide valued services but are rarely fully considered in restoration planning. To address this, I considered how service provisioning will change as restored marsh communities mature and the value of incorporating antipredator training into captive-rearing programs.

For chapter 1, I explored how a facultative mutualism between Atlantic ribbed mussels Geukensia demissa and cordgrass Spartina alterniflora may enhance marsh growth and nitrogen cycling in a eutrophic setting. I created experimental plots in Jamaica Bay, NY, that contained live mussels, mussel shells, or no mussels (control) and measured …

Feral Cats In The Subtropics Of Australia—The Shamrock Station Irrigation Project, Michael Thomas Lohr, Dave Algar, Neil Hamilton, Cheryl Anne Lohr

Research outputs 2022 to 2026

Environmental damage caused by the intensification of agriculture may be compensated by implementing conservation projects directed towards reducing threatening processes and conserving threatened native species. In Australia, feral cats (Felis catus) have been a ubiquitous threatening process to Australian fauna since European colonisation. On Shamrock Station, in the north-west of Western Australia, the Argyle Cattle Company has proposed intensifying agriculture through the installation of irrigation pivots. There is concern that irrigating land and storing agricultural produce may indirectly increase the abundance of feral cats and European red foxes (Vulpes vulpes) on the property, which in turn may negatively impact threatened …

Bottom-Up Drivers Of Future Fire Regimes In Western Boreal North America, Adrianna C. Foster, Jacquelyn K. Shuman, Brendan M. Rogers, Xanthe J. Walker, Michelle C. Mack, Laura L. Bourgeau-Chavez, Sander Veraverbeke, Scott J. Goetz

Aspen Bibliography

Forest characteristics, structure, and dynamics within the North American boreal region are heavily influenced by wildfire intensity, severity, and frequency. Increasing temperatures are likely to result in drier conditions and longer fire seasons, potentially leading to more intense and frequent fires. However, an increase in deciduous forest cover is also predicted across the region, potentially decreasing flammability. In this study, we use an individual tree-based forest model to test bottom-up (i.e. fuels) vs top-down (i.e. climate) controls on fire activity and project future forest and wildfire dynamics. The University of Virginia Forest Model Enhanced is an individual tree-based forest model …

Cold Shock Induces A Terminal Investment Reproductive Response In C. Elegans, Leah Gulyas, Jennifer R. Powell

Biology Faculty Publications

Challenges from environmental stressors have a profound impact on many life-history traits of an organism, including reproductive strategy. Examples across multiple taxa have demonstrated that maternal reproductive investment resulting from stress can improve offspring survival; a form of matricidal provisioning when death appears imminent is known as terminal investment. Here we report a reproductive response in the nematode Caenorhabditis elegans upon exposure to acute cold shock at 2 °C, whereby vitellogenic lipid movement from the soma to the germline appears to be massively upregulated at the expense of parental survival. This response is dependent on functional TAX-2; TAX-4 cGMP-gated channels …
