Dissecting the mechanisms underlying attraction and repulsion to cat sensed cues: Worms and cats aren’t much different

Author Name(s) Brianna Ramos Faculty Advisor(s) Gareth Harris Abstract Organisms across the phyla are capable of sensing an array of sensory cues to control or shape complex behavioral responses needed to survive in an environment consisting of a multitude of attractive and repulsive cues. Mammalian systems extensively use olfactory (odor) and gustatory (taste) behavior to fine tune these sensory-dependent decision-making behaviors. Despite understanding the importance of behavioral responses to odor… Read More »Dissecting the mechanisms underlying attraction and repulsion to cat sensed cues: Worms and cats aren’t much different

To Flee or Not to Flee: Do Avian Chaparral Specialists Escape Wildfire by Flying to Adjacent Unburned Areas?

    Author Name(s) Ariana Cortez, David Morales, Carlin Riley Faculty Advisor(s) Allison Alvarado Abstract Consecutive years of severe drought has recently led to unprecedented and devastating large fires, including in the chaparral habitat of Ventura and Santa Barbara Counties. The population-level response by wildlife to large fire events has not been well-studied. For birds, in particular, it is often assumed that species can fly to safety. The local news media has… Read More »To Flee or Not to Flee: Do Avian Chaparral Specialists Escape Wildfire by Flying to Adjacent Unburned Areas?

    The effects of a nutritional supplement on honey bee brood production

      Author Name(s) John Duarte Faculty Advisor(s) Ruben Alarcon Abstract Since 2014, Ventura County beekeepers have been struggling to keep their colonies alive following the introduction of an unknown pathogen by a migratory beekeeper. In about four weeks, colonies infected with this pathogen can succumb to the disease because the queen stops laying eggs and much of the brood fail to develop into adults. In an effort to keep their colonies… Read More »The effects of a nutritional supplement on honey bee brood production

      Sex differences in decision-making during a multisensory behavior in worms

        Author Name(s) Chane Sevilla, Madison Lewis, Denise Carigo , Gareth Harris Faculty Advisor(s) Gareth Harris Abstract Human behavior and underlying differences in male and female is an intense area in research. Despite numerous studies, the mechanism underlying behavioral differences, such as sensation, perception of sensory cues and decision making, and how it is processed within the human brain is still not understood. Furthermore, the alterations in neural mechanisms resulting in… Read More »Sex differences in decision-making during a multisensory behavior in worms

        Preventing Senescent Associated Age-Related Diseases by Targeting the Anti-apoptotic Protein BCL-XL Using ICM Molsoft

          Author Name(s) Yareli MorenoIsabel MolinaDr. William Munroe Faculty Advisor(s) William Munroe Abstract The accumulation of unhealthy cells in organisms that have entered cellular senescence or irreversible cell cycle arrest has been known to cause many age-related diseases due to their anti-apoptotic properties. As aging increases cells are more prone to entering senescence. It is possible that by regulating senescence pathways, aging can be delayed and in sum enhance the health… Read More »Preventing Senescent Associated Age-Related Diseases by Targeting the Anti-apoptotic Protein BCL-XL Using ICM Molsoft

          Patterns among elevational distribution and prevalence of a fungal pathogen in Andean water frogs (Telmatobius)

            Author Name(s) Celena CamarilloBenjamin Martinez Faculty Advisor(s) Rudolf von May Abstract The Andean water frogs in the genus Telmatobius occupy various elevations (1000-5244 m) and are experiencing an array of threats in South America. In this study, we focus on the wild populations of these amphibians by reviewing the current data on elevational distribution, range and threat status. The data and analyses were acquired from the International Union for Conservation… Read More »Patterns among elevational distribution and prevalence of a fungal pathogen in Andean water frogs (Telmatobius)

            Investigation of aromatase inhibitors’ ability to affect pathways required for endometriosis formation

              Author Name(s) Alexis Figueroa Faculty Advisor(s) Dr.Munroe Abstract Senolytic drugs are being studied for their ability to selectively clear out (or kill) senescent cells that lead to aging, tissue damage, and potentially fatal diseases. This project aims to determine if senolytic agents could potentially be used for the treatment of endometriosis. Endometriosis is a gynecological disease in which endometrial (uterine lining) tissue implants itself outside of the uterus. Endometriosis affects… Read More »Investigation of aromatase inhibitors’ ability to affect pathways required for endometriosis formation

              Screening the effects of Psilocybin on complex behavior in worms

              Author Name(s) Alyssa Garbarino Leighton Ledesma, Maria Carillo, Nina Scalise, Chase Khedmatgozar, Chase Baker and Gareth Harris Faculty Advisor(s) Gareth Harris Abstract Neuro-pharmacological agents and their actions have been an intensive area of research in relation to treatment of neurological disorders and understanding human behavior. Both medically prescribed and recreationally used chemical compounds can have profound short and long-term effects on the neuro mechanisms in mammals, influencing decision making and… Read More »Screening the effects of Psilocybin on complex behavior in worms

              Glutamatergic transmission regulates worms staying on a food patch in C. elegans

                Author Name(s) Ariana Perez Trevor Wolf Gianina Pontrelli Gareth Harris Faculty Advisor(s) Gareth Harris Abstract The sensation of environmental cues and subsequent decisions made as a result of the processing of specific sensory cues underlies a myriad of behavioral responses that control every-day life decisions and ultimately survival in many organisms. Despite the appreciation that organisms can sense, process, and translate sensory cues into a behavioral response, the precise neural… Read More »Glutamatergic transmission regulates worms staying on a food patch in C. elegans

                Range and conservation status of harlequin frogs and glass frogs

                Author Name(s) Siomara ZendejasJonathan AlvaradoJenny Juarez Faculty Advisor(s) Rudolf von May Abstract Given growing concern about worldwide amphibian population declines, it is critical to conduct continuous conservation status assessments to assist in species and habitat protection programs. In the study, we review the current data on geographic distribution, elevational range, and threat status of harlequin grogs (Atelopus) and glass frogs, two groups of Neotropical amphibians facing similar threats.Our main goal… Read More »Range and conservation status of harlequin frogs and glass frogs
