A Multivariate Approach To Assessing Landscape Structure Effects On Wildlife Crossing Structure Use, Thomas J. Yamashita, Humberto L. Perotto-Baldivieso, David B. Wester, Kevin W. Ryer, Richard J. Kline, Michael E. Tewes, John H. Young Jr., Jason V. Lombardi

School of Earth, Environmental, & Marine Sciences Faculty Publications

Background

Complexity in landscape structure is often assessed using individual metrics related to ecological processes. However, this rarely incorporates important relationships among metrics and may miss landscape structure effects. Multivariate statistics provide techniques for assessing overall landscape structure effects. We assessed how multivariate statistics could be used to connect landscape structure with an ecological process [bobcat (Lynx rufus) wildlife crossing structure (WCS) use]. We tested how landscape structure at WCS sites compared to the surrounding landscape and how structure affected detections at WCS sites. Our study was conducted in Cameron County, Texas, USA where WCSs are in various …

Stable Isotope Analysis Of Antipatharian Diets From The Northwestern Gulf Of Mexico, Keir J. Macartney, Victoria Salinas, Zachary Rivera, David Hicks

School of Earth, Environmental, & Marine Sciences Faculty Publications

Antipatharians, or black corals, form a key component of the benthic fauna found throughout the Gulf of Mexico (GOM). In the northwestern GOM, they are a common member of the communities found on the natural relic coral—algal banks known as the South Texas Banks as well as on artificial reefs. They are known to provide important habitat for many ecologically and economically important species in the area but are relatively understudied. Here we present a study on their trophic ecology using stable isotope analysis of carbon and nitrogen from 2 species, Antipathes atlantica and Stichopathes luetkeni from a mesophotic artificial …

Semiautomated Generation Of Species-Specific Training Data From Large, Unlabeled Acoustic Datasets For Deep Supervised Birdsong Isolation, Justin Sasek, Brendan Allison, Andrea Contina, David Knobles, Preston Wilson, Timothy Keitt

School of Integrative Biological & Chemical Sciences Faculty Publications

Background

Bioacoustic monitoring is an effective and minimally invasive method to study wildlife ecology. However, even the state-of-the-art techniques for analyzing birdsongs decrease in accuracy in the presence of extraneous signals such as anthropogenic noise and vocalizations of non-target species. Deep supervised source separation (DSSS) algorithms have been shown to effectively separate mixtures of animal vocalizations. However, in practice, recording sites also have site-specific variations and unique background audio that need to be removed, warranting the need for site-specific data.

Methods

Here, we test the potential of training DSSS models on site-specific bird vocalizations and background audio. We used a …

Shining Light On The Invisible: Fluorescent Detection Of Reactive Oxygen Species, Alex Zuo

Research Colloquium

Background

Reactive oxygen species (ROS) play an important role in cell signaling and homeostasis. However, overproduction of ROS leads to oxidative stress, as well as other related diseases, including cancer, neurodegenerative diseases, and cardiovascular disorders. Conventional ROS detection methods are limited by their low sensitivity and low specificity in real-time measurements. Fluorescent probes can offer valuable tools to detect ROS in biological systems. This study is focused on the detection of ROS formation during hypoxia and reoxygenation.

Methods

We used fluorescence detection techniques to study ROS in isolated rodent skeletal muscle models, which were exposed to alternating hyperoxia and hypoxia. …

Investigating Therapeutic Activity Of Br-Ormeloxifene (Br-Orm) Against Cervical Cancer, Mohammed Sikander, Shabnam Malik, John Apraku, Sonam Kumari, Parvez Khan, Daniel Zubieta, Hassan Mandil, Aditya Ganju, Bhavin Chauhan, Maria C. Bell, Man Mohan Singh, Sheema Khan, Murali Yallapu, Fathi T. Halaweish, Meena Jaggi, Subhash Chauhan

Research Colloquium

Aberrant activation of β-catenin signaling is strongly associated with cancer proliferation, invasion, migration, and metastasis, thus small molecules that can inhibit this pathway might have great clinical significance. Our molecular modeling studies suggest that Ormeloxifene (ORM), a triphenylethylene molecule docks with β-catenin, and its brominated analogue (Br-ORM) bind more effectively with relatively less energy (-7.6 kcal/mol) to the active site of β-catenin as compared to parent ORM. Herein, we report the synthesis and characterization of a Br-ORM by NMR and FTIR, as well as its anti-cancer potential in cervical cancer models in vitro and in vivo. Br-ORM treatment effectively …

Ormeloxifene Suppresses Emt In Hepatocellular Carcinoma By Targeting Β-Catenin Signaling Pathway, Shabnam Malik, Mohammed Sikander, Daniel Zubieta, Anyssa Rodriguez, Murali Yallapu, Meena Jaggi, Subhash C. Chauhan

Research Colloquium

Background: Hepatocellular carcinoma (HCC) is one of the deadliest cancers, with a five-year survival rate. While Sorafenib (SRB) is the standard therapy, it is only effective in prolonging survival for some patients, emphasizing the urgent need for alternative treatment options. Resistance to apoptosis is a defining characteristic of cancer cells and a crucial factor in cancer recurrence and relapse. Although, anticancer potential of the FDA-approved compound Ormeloxifene (ORM), which has well-defined pharmacokinetic and pharmacodynamic properties, has been explored in a variety of cancers, its efficacy in HCC has remained unknown. Therefore, the purpose of this study was to investigate the …

Enhanced Bmp Signaling Via Alk2 In Osteoclasts Decreases Bone Density In Mice, Yolanda V. Gutierrez, Hiroyuki Yamaguchi, Yuji Mishina, Yoshihiro Komatsu

Research Colloquium

Bone remodeling is a complex biological process that has been extensively studied. Bone Morphogenetic Proteins (BMPs) are recognized as one of the critical growth factors that coordinate bone remodeling. Previous studies have demonstrated that BMP signaling in osteoclasts has a positive effect on osteoclast function. However, little is known about how each BMP type I receptors control osteoclastogenesis. To investigate this question, we utilized the Cre-LoxP system to specifically activate BMP signaling through ALK2 in mice. We utilized Cathepsin K (Ctsk)-Cre driver to activate BMP signaling in osteoclasts in mice. Compared with aged- and gender-matched controls, gain-of-function of BMP mutant …

Preparing For The Worst: Enhancing Seedling Traits To Reduce Transplant Shock In Semi-Arid Regions, Douglas Evan Mainhart, Bradley O. Christoffersen, R. Alexander Thompson, Charlotte M. Reemts, Alejandro Fierro-Cabo

School of Integrative Biological & Chemical Sciences Faculty Publications

The spatial extent of semi-arid hot regions is forecasted to grow through the twenty-first century, complicating restoration and reforestation plans. In arid and semi-arid climates, seedlings are more susceptible to transplant shock due to lower soil moisture throughout the year. Determining strategies to reduce seedling stress and improve survival post-planting will be paramount to continued reforestation efforts in a changing climate. We quantified seedling physiological, morphological, and field performance (mortality and growth) response for five species native to the semi-arid region of South Texas (Erythrina herbacea L., Celtis pallida Torr., Fraxinus berlandieriana DC, Malpighia glabra L., and Citharexylum berlandieri B.L …

A New Record Of Fleas From Nilgai Antelope In Southern Texas And Fleas From Other Wildlife, Sarah E. Mays Maestas, Jason Tidwell, John A. Goolsby, Lauren P. Maestas

School of Integrative Biological & Chemical Sciences Faculty Publications

Wildlife are hosts of ectoparasites, such as fleas and ticks that may transmit human and animal pathogens. Little is known about the ecology of many ectoparasite species native to southern Texas, or their role in pathogen maintenance and transmission. Much attention has been given to the role of nonnative nilgai antelope as cattle fever tick hosts and agents of dispersal, but little attention has been given to other ectoparasites that may utilize nilgai antelope as hosts. As southern Texas is a hot-spot for flea-borne (murine) typhus, it is important to examine flea species presence, abundance, and host use in this …

Differentiation Activates Mitochondrial Opa1 Processing In Myoblast Cell Lines, Harpreet Kaur, Omar Carrillo, Iraselia Garcia, Isaiah Ramos, Shaynah St. Vallier, Patrick De La Torre, Alma Lopez, Megan Keniry, Daniela Bazan, Jorge Elizondo, Robert Gilkerson

School of Integrative Biological & Chemical Sciences Faculty Publications

Mitochondrial optic atrophy-1 (OPA1) plays key roles in adapting mitochondrial structure to bioenergetic function. When transmembrane potential across the inner membrane (Δψm) is intact, long (L-OPA1) isoforms shape the inner membrane through membrane fusion and the formation of cristal junctions. When Δψm is lost, however, OPA1 is cleaved to short, inactive S-OPA1 isoforms by the OMA1 metalloprotease, disrupting mitochondrial structure and priming cellular stress responses such as apoptosis. Previously, we demonstrated that L-OPA1 of H9c2 cardiomyoblasts is insensitive to loss of Δψm via challenge with the protonophore carbonyl cyanide chlorophenyl hydrazone (CCCP), but that CCCP-induced OPA1 processing is activated upon …

School of Earth, Environmental, & Marine Sciences Faculty Publications

Microeukaryotes are key contributors to marine carbon cycling. Their physiology, ecology, and interactions with the chemical environment are poorly understood in offshore ecosystems, and especially in the deep ocean. Using the Autonomous Underwater Vehicle Clio, microbial communities along a 1050 km transect in the western North Atlantic Ocean were surveyed at 10–200 m vertical depth increments to capture metabolic signatures spanning oligotrophic, continental margin, and productive coastal ecosystems. Microeukaryotes were examined using a paired metatranscriptomic and metaproteomic approach. Here we show a diverse surface assemblage consisting of stramenopiles, dinoflagellates and ciliates represented in both the transcript and protein fractions, …

Short-Term Hiit Impacts Hdl Function Differently In Lean, Obese, And Diabetic Subjects, Lin Zhu, Julia An, Thao Luu, Sara M. Reyna, Puntip Tantiwong, Apiradee Sriwijitkamol, Nicolas Musi, John M. Stafford

School of Medicine Publications

Introduction: High density lipoproteins (HDL) exert cardiovascular protection in part through their antioxidant capacity and cholesterol efflux function. Effects of exercise training on HDL function are yet to be well established, while impact on triacylglycerol (TG)-lowering has been often reported. We previously showed that a short-term high-intensity interval training (HIIT) program improves insulin sensitivity but does not inhibit inflammatory pathways in immune cells in insulin-resistant subjects. The purpose of this study is to evaluate HDL function along with changes of lipoproteins after the short-term HIIT program in lean, obese nondiabetic, and obese type 2 diabetic (T2DM) subjects.

Methods: All individuals …

School of Earth, Environmental, & Marine Sciences Faculty Publications

We present a framework for strategic dam planning under uncertainty, which includes GHG emissions mitigation as a novel objective. We focus on the Mekong River Basin, a fast‐developing region heavily relying on river‐derived ecosystem services. We employ a multi‐objective evolutionary algorithm to identify strategic dam portfolios for different hydropower expansion targets, using process‐related and statistical models to derive indicators of sediment supply disruption and GHG emissions. We introduce a robust optimization approach that explores variations in optimal portfolio compositions for more than 5,000 state‐of‐ the‐world configurations, regarding sediment origins and trapping and GHG emissions. Thus, we can rank dam projects' …

Utilizing Unmanned Aerial Systems (Uas) And Computer Software To Assess Effects Of Cover Crops On Cash Crop Volumetric Mass And Plant Height, Carlos Andres Garcia Patlan

Theses and Dissertations

Sustainability in agriculture starts with the health of soil-- from its productivity and fertility, to its ability to retain water during droughts and allow for drainage during rain. One approach of improving soil health is the use of cover crops, a practice associated with improved nutrient availability in soils, the promotion of soil biodiversity and organic matter to improve density and structure, effective weed management, and ultimately improved yields of subsequent cash crops. Assessing the cumulative impacts of cover crops is difficult, with various metrics and indicators. Crop dry weight may be a way to predict the effects cover crops …

Documenting The Spatial And Temporal Dynamics Of Pair-Rule Genes In The Early Tribolium Embryo, Hasan Mahmud

Theses and Dissertations

Although Insects and vertebrates have different anatomical structures, they possess similar mechanisms for segmenting during embryogenesis. Clock and wavefront model exhibit a similar pattern of division as observed in Drosophila, like vertebrates, which emphasizes fundamental principles in the field of developmental biology. In contrast to Drosophila, the insect Tribolium castaneum exhibits posterior segmentation originating from the growth zone. The pair-rule genes’ expression is characterized by oscillatory patterns, which are controlled by a segmentation clock. Researchers found that the speed regulation model combines oscillatory and sequential gene activities to shape both elongating and non-elongating embryonic tissues. The adaptability of this model …

Co-Localization Of Osteoclasts Differentiation Markers In An Implant Model In Diabetic Mice, Diego Adobbati, Deborah Rocha Seixas, Danieli Rodrigues, Claudia C. Biguetti

School of Podiatric Medicine - Student Research

Introduction and Hypothesis: Diabetes can impair implant osseointegration and impact implant functionality. While significant research has focused on osteogenesis during the osseointegration, little attention has been given to pre-osteoclast differentiation. We hypothesize that diabetes increases pre-osteoclast activity potentially leading to implant failure. This study aims to identify and localize osteoclast markers, specifically DC-STAMP (Dendritic Cell-Specific Transmembrane Protein) and NFATc2 (Nuclear Factor of Activated T-cells, cytoplasmic 2), in diabetic (D) and non-diabetic (ND) mice.

Methodology: Twenty-four 16-week-old male 129 Sv mice (12 diabetic and 12 non-diabetic) underwent implantation with a 0.5x1.5 mm commercially pure titanium screw in the right maxillary bone. …

School of Earth, Environmental, & Marine Sciences Faculty Publications

Roads negatively impact wildlife through habitat fragmentation, loss of habitat connectivity, and wildlife-vehicle collisions, thus road mitigation structures, such as wildlife crossing structures (WCS), wildlife guards (WG), and fencing are commonly used to address this issue all over the world, including in the United States. In South Texas, such structures were built or modified along a State Highway in an effort to address road mortality for the endangered ocelot (Leopardus pardalis) and non-target wildlife species. The goal of this study was to examine temporal changes in wildlife interactions with WCS and WG during and after their construction and …

Red Harvester Ant, Pogonomyrmex Barbatus, Nests Impact Soil Compaction But Not Temperature In Peri-Urban Habitats Of The Lower Rio Grande Valley, Geovanni Hernandez, Hannah J. Penn, Richard Cano, Lilly Victoria Elliott-Vidaurri, Robin A. Choudhury

School of Earth, Environmental, & Marine Sciences Faculty Publications

Ants are vital ecosystem engineers that can influence soil properties, subsequent soil processes, and associated biota via underground nest construction. Harvester ants consume seeds and are often found in arid areas. They frequently alter the soil chemistry and bulk density of the soils in and around their nest sites. Many species of harvester ants also intentionally remove vegetation around their nest openings, which creates cones or discs of bare soil that may further alter soil temperatures. However, much of the work to study the impacts of harvester ants on soil properties has occurred in shrubland and grassland settings rather than …
