Alfred Russel Wallace Notes 28. Wallace's 'Change Of Mind', Revisited, Charles H. Smith 2023 Western Kentucky University

Alfred Russel Wallace Notes 28. Wallace's 'Change Of Mind', Revisited, Charles H. Smith

Faculty/Staff Personal Papers

Alfred Russel Wallace (1823−1913) is best known for his work on the theory of evolution by natural selection, and studies on biogeography. This fame has not, however, prevented appraisals of his work that sometimes depart from rational interpretations of his actual words. In this study, the frequently-offered notion that his adoption of spiritualism in late 1866 caused him to reverse himself on the universality of natural selection is taken to task, with arguments linked to his own words on the subject.

Freshwater Macroinvertebrate Communities In Baldwin County, Georgia, Heath Michael Ghioto, Michelle K. Murdock, Nadya S. Gutierrez, Kristine N. White Ph.D. 2023 Georgia College & State University

Freshwater Macroinvertebrate Communities In Baldwin County, Georgia, Heath Michael Ghioto, Michelle K. Murdock, Nadya S. Gutierrez, Kristine N. White Ph.D.

Georgia Journal of Science

Freshwater ecosystems are critical habitats for maintaining biodiversity, often providing refuge for organisms especially in urban settings. Baldwin County, GA is home to many freshwater lakes that are part of the Oconee River watershed. Despite ongoing water quality monitoring, aquatic macroinvertebrates are under studied in the area. Aquatic macroinvertebrate diversity of one forested and one residential lake in Milledgeville, GA was documented for the first time. Despite low sample size, community composition was significantly different between lakes, with 27 families in Lake Laurel (forested), 44 families in Lake Oliver Hardy (residential), and only 19 families collected from both lakes. Seasonal …

Southern California Marine Protected Areas Promote Bolder Fish Populations, Lucian Himes, Florybeth F. La Valle 2023 Pepperdine University

Southern California Marine Protected Areas Promote Bolder Fish Populations, Lucian Himes, Florybeth F. La Valle

Summer Undergraduate Research in Biology Program

Marine protected areas (MPAs) aim to protect habitats and ecosystems to promote the diversity and health of marine populations. To evaluate the health of fish populations within and outside of MPAs in Southern California, we used flight initiation distance (FID). FID is the distance at which an individual will flee from a perceived predator and is a direct measure of boldness. Lower FIDs are indicative of bolder populations. Lower FID values indicate that fish will have the opportunity to dedicate less energy to fleeing from predators which could then be used for increased foraging. Data was collected from eight locations …


Textbook Tasks For Social Change: Instantiation Of Development Debates And Interposition Of Pedagogical Interventions In Media Literacy Education, John N. Ponsaran 2023 University of the Philippines Manila

Textbook Tasks For Social Change: Instantiation Of Development Debates And Interposition Of Pedagogical Interventions In Media Literacy Education, John N. Ponsaran

Journal of Sustainable Social Impact

As materialization of their discursive stance as instructional communicators and media producers, textbook authors instantiate various development debates as well as interpose a wide range of pedagogical interventions for critical reflection and adoption by learners. This qualitative study sought to situate these development debates and the counterpart pedagogical interventions within the context of textbook task design as an application and embodiment of social justice communication. The development debates serve as the proposed contexts for media text analyses, reflective exercises, case studies, and media production, among others. Correspondingly, the interposition of interventions allows students to make sense of and act upon …

Climate Science Research Articles

Habitat loss is a key factor in the ongoing freshwater biodiversity crisis. A promising way to help tackle the rapid decline in freshwater biodiversity is to improve the potential for artificial wetlands to provide habitat for aquatic wildlife. Farm dams (also known as agricultural ponds) are among the most abundant waterbodies in agricultural landscapes and can act as “oases” against droughts for many species. Despite their prominent role in agriculture, predictive models to evaluate their ecological potential are yet to emerge. Here we use a continental-scale data set of 104,013 audio recordings from citizen scientists to identify and locate 107 …


D-Shaped Nematode Eggs In The Feces Of Rangifer Tarandus: A Story In Pictures, Olga A. Loginova 2023 A.N. Severtsov Institute of Ecology and Evolution, Russian Academy of Sciences, Moscow, Russia

D-Shaped Nematode Eggs In The Feces Of Rangifer Tarandus: A Story In Pictures, Olga A. Loginova

MANTER: Journal of Parasite Biodiversity

D-shaped nematode eggs in the feces of Rangifer tarandus are expected to be oxyurid nematodes (Nemata: Oxyurida) of the genus Skrjabinema. The species S. tarandi is considered species-specific for this host. There is no consensus regarding the cross-infection of reindeer and sheep with S. ovis and S. tarandi. The drawings proposed by descriptors complicate differential diagnostics. Micrographs of S. tarandi eggs obtained via light microscopy and scanning electron microscopy as well as photographs of S. ovis eggs and drawings made on their basis are proposed to confidently distinguish between representatives of these two species, taking into account morphometric data. Thus, …


The Uses And Limitations Of Citizen Science For Monitoring The Australian Grey Nurse Shark (Carcharias Taurus) Population, Leah Corckran 2023 SIT Study Abroad

The Uses And Limitations Of Citizen Science For Monitoring The Australian Grey Nurse Shark (Carcharias Taurus) Population, Leah Corckran

Independent Study Project (ISP) Collection

iNaturalist is a citizen science photographic database, which is an underutilized resource in photographic identification research studies. Grey nurse sharks are critically endangered and there is a lack of knowledge regarding the estimated population size, longevity, and interactions with fisheries of this species off the coasts of Australia. To determine how photos submitted to iNaturalist can be used in Carcharias taurus conservation, the photographs were evaluated on a number of criteria including: location, date, visibility of spot patterns, visible sex characteristics, and visible injuries. In total, 814 photographs of grey nurse sharks were obtained from the iNaturalist database. Only 23.2% …

Community Complexity Of A Pollination Network: Analysis Of Plant-Pollinator Interactions In The Eastern Ecuadorian Cloud Forest, Anisa López-Ruiz

Independent Study Project (ISP) Collection

Global declines in pollinators and temporal/spatial mismatches between plants and pollinators threaten the integrity of plant-pollinator networks. Ecological network analysis provides a powerful framework for understanding the dynamics of plant-pollinator networks and measures of community complexity that can help inform areas of priority in conservation. This study observed a plant-pollinator network in a secondary forest close to the Río Zuñac Reserve in the eastern Ecuadorian cloud forest to identify assemblages of plants and pollinators and evaluate measures of community complexity, including specialization and nestedness. Flowering plants were identified and observed along a 1.2 km transect, and floral visitors to these …


Friends In High Places: Establishing Pollination Networks For The Páramos Of Central Ecuador, Emma Diaz 2023 SIT Study Abroad

Friends In High Places: Establishing Pollination Networks For The Páramos Of Central Ecuador, Emma Diaz

Independent Study Project (ISP) Collection

Well-known for being a global biodiversity hotspot, the Andean Páramos hosts a unique array of floristic diversity seen nowhere else in the world (Luteyn, n.d.). With the resiliency of this ecosystem dependent on the successful reproduction of these plants, it is crucial to understand the pollination network which sustains them. Modern-day research has outlined networks in the Chilean, Venezuelan, and Argentinean Páramos, but one has yet to be defined for Ecuador, despite being the suspected home to nearly half of floristic diversity in the Páramos (Arroyo et al., 1985; Pelayo et al., 2021; Medan et al., 2023; Caranqui et al., …


Reef Fish Wariness Behavior: Fish Flight Initiation Distance Mediated By Territoriality And Body Size In Three Reef Sites Off The Western Coast Of Isla Colón, Bocas Del Toro, Panamá, Alina G. Irvine 2023 SIT Study Abroad

Reef Fish Wariness Behavior: Fish Flight Initiation Distance Mediated By Territoriality And Body Size In Three Reef Sites Off The Western Coast Of Isla Colón, Bocas Del Toro, Panamá, Alina G. Irvine

Independent Study Project (ISP) Collection

Coral reefs are highly productive and diverse underwater ecosystems, providing a variety of environmental services including sand generation, nutrient processing, fish supply, and tourism. However, coral reefs have been increasingly impacted by natural and anthropogenic disturbances, which has negatively affected fish security within their environment. A significant observation is the reduction in evasive behaviors among reef fish in marine reserves compared to those exposed to anthropogenic threats. The present research aims to investigate the factors mediating fish wariness behavior through an exploration of the roles of territoriality and body size on fish flight initiation distance (FID). FID is the distance …


Lha, Lu, And Shipda: Religious Landscape In A Conservation Area, Luke Stumpfl 2023 SIT Study Abroad

Lha, Lu, And Shipda: Religious Landscape In A Conservation Area, Luke Stumpfl

Independent Study Project (ISP) Collection

Living in a political, cultural, and geographic border region between Nepal and Tibet (People’s Republic of China), the families of Tsum Valley face many demands from their sociopolitical, religious, and economic climate. Practicing Tibetan Buddhism, the people uphold a set of rules implemented by the community with leadership from Serap Dorje Drukpa Rinpoche over 100 years ago that prohibits the intentional murder of all animals. Hailed by leaders and scholars as a haven of biodiversity conservation due to this customary-turned- municipal law, Tsum Valley also exists within Manaslu Conservation Area governed by an entity of the federal government of Nepal …

Alfred Russel Wallace Notes 27. When Wallace Broke With Darwin., Charles H. Smith

Faculty/Staff Personal Papers

The year 1866 was the first year Alfred Russel Wallace showed definite signs of breaking with Darwin over the limits of natural selection. Attention is drawn to a July 1866 exchange of letters between the two, and how this foreshadowed what followed.


Civilian Oversight Of Police Through The Lens Of Polarities Of Democracy, Joseph A. McMillan, Jacqueline D. Smith, William J. Benet 2023 Walden University

Civilian Oversight Of Police Through The Lens Of Polarities Of Democracy, Joseph A. Mcmillan, Jacqueline D. Smith, William J. Benet

Journal of Sustainable Social Impact

Following the murder of George Floyd, the U.S. Congress called upon the National Organization for Black Law Enforcement Executives (NOBLE) to play a role in the reimagining of policing in America, including a transformation of policing from a warrior to a guardian mentality. In turn, NOBLE partnered with the Institute for Polarities of Democracy (the Institute) to conduct an analysis of the 21st Century Policing Report (the Report), which focused on addressing a myriad of issues that challenged the relationship between the police and communities. The Report determined there were six “pillars” necessary for effective policing in America, including (1) …


The Himalayan Uplift And Evolution Of Aquatic Biodiversity Across Asia: Snowtrout (Cyprininae: Schizothorax) As A Test Case, Binod Regmi, Marlis R. Douglas, Karma Wangchuk, Zachery D. Zbinden, David R. Edds, Singye Tshering, Michael E. Douglas 2023 University of Arkansas, Fayetteville

The Himalayan Uplift And Evolution Of Aquatic Biodiversity Across Asia: Snowtrout (Cyprininae: Schizothorax) As A Test Case, Binod Regmi, Marlis R. Douglas, Karma Wangchuk, Zachery D. Zbinden, David R. Edds, Singye Tshering, Michael E. Douglas

Biological Sciences Faculty Publications and Presentations

Global biodiversity hotspots are often remote, tectonically active areas undergoing climatic fluctuations, such as the Himalaya Mountains and neighboring Qinghai-Tibetan Plateau (QTP). They provide biogeographic templates upon which endemic biodiversity can be mapped to infer diversification scenarios. Yet, this process can be somewhat opaque for the Himalaya, given substantial data gaps separating eastern and western regions. To help clarify, we evaluated phylogeographic and phylogenetic hypotheses for a widespread fish (Snowtrout: Cyprininae; Schizothorax) by sequencing 1,140 base pair of mtDNA cytochrome-b (cytb) from Central Himalaya samples (Nepal: N = 53; Bhutan: N = 19), augmented with 68 GenBank …

Bryophyte (Sl) Growth And Environmental Factors Along An Altitudinal Gradient On Cerro Gaital, El Valle, Coclé, Panamá, Julian Grace-Martin

Independent Study Project (ISP) Collection

Research on bryophytes (SL) in the tropics has been lacking compared with the high number of species found there and the potential benefit of bryophytes (SL) as indicators of pollutants and other forms of human disturbance. This study investigated whether or not bryophyte (SL) growth patterns showed relation when compared with environmental factors on the mountain Cerro Gaital in El Valley, Panamá. Whether or not bryophytes (SL) are present, extent of the area covered by their growth, and height of their growth are all aspects of bryophyte (SL) growth that were used. In this study, these three aspects are compared …

Flujos De Servicios Ecosistémicos En Un Área Marina Protegida Del Atlántico Sur: Perspectivas Desde El Análisis De La Teoría De Redes, Mitch Porter

Independent Study Project (ISP) Collection

En cuestiones de gestión de áreas protegidas, los servicios ecosistémicos se tienen cada vez más en cuenta junto con la conservación de la biodiversidad. Sin embargo, las decisiones que se toman sobre la conservación de los servicios ecosistémicos no suelen incluir los posibles efectos en cascada de la pérdida de biodiversidad sobre la provisión de servicios. Los conocimientos de la teoría de redes y los estudios de robustez pueden proporcionar una metodología para evaluar la vulnerabilidad de estos servicios frente la estructura trófica de los ecosistemas que los proveen. A través de una serie de simulaciones de extinción para la …
