A New Species Of Ataenius Harold (Coleoptera: Scarabaeidae: Aphodiinae) From The Southeastern United States, With A Lectotype Designation, Kyle E. Schnepp, Krystal L. Ashman

Insecta Mundi

A new species of Ataenius Harold, Ataenius thomasi Schnepp and Ashman (Coleoptera: Scara­baeidae: Aphodiinae), from Florida, Georgia, and Mississippi, U.S.A. is described. The lectotype for Ataenius brevis Fall is designated.

In the United States and Canada the genus Ataenius Harold (Coleoptera: Scarabaeidae: Aphodiinae) contains 46 species (Stebnicka 2007; Smith 2009). The most recent faunal review of this genus in these countries was completed by Cartwright (1974). However, several species in that paper have been moved to other genera or syn­onymized (Stebnicka 2007). Stebnicka and Lago (2005) provide a key and catalog to the Ataenius strigatus group. Specimens of a putative …

Exploration Of Local Microorganisms From Rumen And Their Potential To Make Silage From Agricultural Waste, Purnamasari Listya, Purnomo Hari, Setyawan Hidayat Bambang

ASEAN Journal on Science and Technology for Development

Agricultural wastes are very diverse in type and have low nutrient values, especially in lignin and cellulose, which are difficult to digest. One way of overcoming this problem is by biological treatment using microorganisms, also known as silage. The availability of bio-activators that are both cost-efficient and easy to make further suggests that using local microorganisms may be an effective possible solution. This study focused on processing food crop waste (corn leaves) into silage using local microorganisms as the bio-activators. Research took place in the Agrotechnology Laboratory, University of Jember. The experimental design was completely randomized with four treatments: Treatment …

Vision-Based Size Estimation And Centroid Positioning Of Partially Occluded Fruits, Kyu Mya Thin Kyu, Aung Nay Zar

ASEAN Journal on Science and Technology for Development

The objective of this study was to propose a simple and efficient image processing algorithm for estimating the size and centroid of partially occluded round fruits. In the proposed method, the size and centroid of partially occluded fruit were estimated based on the mathematical properties of the arc-radius. The experimental tests were conducted in a laboratory with orange, Sunkist, apple, and tomato fruits by setting different occlusion conditions. The occlusion percentage was varied between 0% and 90%. The accuracy and processing time of the proposed method were compared with that of the widely-used conic-section circle fitting method. The results showed …

“We’Re, Like, The Most Unhealthy People In The Country”: Employing An Equity Lens To Reduce Barriers To Healthy Food Access In Rural Appalachia, Kathryn Cardarelli, Emily M. Dewitt, Rachel Gillespie, Heather Norman-Burgdolf, Natalie Jones, Janet Tietyen Mullins

Dietetics and Human Nutrition Faculty Publications

Introduction

Obesity disproportionately affects rural communities, and Appalachia has some of the highest obesity rates in the nation. Successful policy, systems, and environmental (PSE) interventions to reduce obesity must reflect the circumstances of the population. We used a health equity lens to identify barriers and facilitators for healthy food access in Martin County, Kentucky, to design interventions responsive to social, cultural, and historical contexts.

Methods

We conducted 5 focus groups in Martin County, Kentucky, in fall 2019 to obtain perspectives on the local food system and gauge acceptability of PSE interventions. We used grounded theory to identify perceived barriers and …

Two New Species Of Pharaxonotha Reitter Among The Early-Diverging Lineages, With A Key To The Species Of The Genus (Coleoptera: Erotylidae: Pharaxonothinae), Paul E. Skelley, William Tang

Insecta Mundi

Two species of the early-diverging lineages of Pharaxonotha Reitter (Coleoptera: Erotylidae: Pharaxonothinae) are described: Pharaxonotha taylori Skelley and Tang, new species, and Pharaxonotha thomasi Skelley and Tang, new species. A new key to described species of Pharaxonotha, based on previously unused characters, is presented.

In recent phylogenetic analyses of beetle diversity based on a large nuclear data set (McKenna et al. 2019) and on nuclear and mitochondrial legacy loci (Powell, pers. comm. 2020), the New World genus Pharaxonotha Reitter (Erotylidae: Pharaxonothinae) was shown to be sister to all remaining Erotylidae in a clade comprised of the Erotylidae+Phytophaga, …

Modeling Action Potential Reversals In Tunicate Hearts, John W. Cain, Luran He, Lindsay D. Waldrop

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Tunicates are small invertebrates which possess a unique ability to reverse flow in their hearts. Scientists have debated various theories regarding how and why flow reversals occur. Here we explore the electrophysiological basis for reversals by simulating action potential propagation in an idealized model of the tubelike tunicate heart. Using asymptotic formulas for action potential duration and conduction velocity, we propose tunicate-specific parameters for a two-current ionic model of the action potential. Then, using a kinematic model, we derive analytical criteria for reversals to occur. These criteria inform subsequent numerical simulations of action potential propagation in a fiber paced at …

African Land Mammal Ages, John Van Couvering, Eric Delson

Publications and Research

We define 17 African land mammal ages, or AFLMAs, covering the Cenozoic record of the Afro-arabian continent, the planet’s second largest land mass. While fossiliferous deposits are absent on the eroded plateau of the continent’s interior, almost 800 fossil genera from over 350 locations have now been identified in coastal deposits, karst caves, and in the Neogene rift valleys. Given a well-developed geochronologic framework, together with continuing revision to the fossil record—both stimulated by the story of human evolution in Africa—and also to compensate for the variation in fossil ecosystems across such great distances, the AFLMAs are biochronological units defined …

Water Availability For Cannabis In Northern California: Intersections Of Climate, Policy, And Public Discourse, Betsy Morgan, Kaitlyn Spangler, Jacob Stuivenvolt-Allen, Christina N. Morrisett, Mark W. Brunson, Shih-Yu Simon Wang, Nancy Huntly

Biology Faculty Publications

Availability of water for irrigated crops is driven by climate and policy, as moderated by public priorities and opinions. We explore how climate and water policy interact to influence water availability for cannabis (Cannabis sativa), a newly regulated crop in California, as well as how public discourse frames these interactions. Grower access to surface water covaries with precipitation frequency and oscillates consistently in an energetic 11–17 year wet-dry cycle. Assessing contemporary cannabis water policies against historic streamflow data showed that legal surface water access was most reliable for cannabis growers with small water rights ( < 600 m³) and …

Effect Of Treadmill Exercise And Probiotic Ingestion On Motor Coordination And Brain Activity In Adolescent Mice, Junechul Kim, Bo-Eun Yoon

Kinesiology Faculty Publications (Archived)

High-intensity exercise can lead to chronic fatigue, which reduces athletic performance. On the contrary, probiotic supplements have many health benefits, including improvement of gastrointestinal health and immunoregulation. However, the effects of probiotics combined with exercise interventions on motor functions and brain activity have not been fully explored. Therefore, this study aimed to identify the effects of probiotic supplements and aerobic exercise on motor function, immune response, and exercise intensity and probiotic ingestion. After four weeks of intervention, the motor functions were assessed by rotarod test, then the levels of cytokines, gamma-aminobutyric acid (GABA), and glutamate were detected. The improvement caused …
