Microtubules in Plant Growth and Morphogenesis

Dr. Jessica Lucas

Plant Biologist, Assistant Professor, Santa Clara University

View Now

Request Transcript

One of the main differences between plant and animal cells lies with tiny structures within cells that are made of protein and called microtubules. As Dr. Lucas explains, one of the major differences between plant and animal cells is that the microtubules are organized in completely different ways. She notes their importance to both growth (an organism getting bigger, increasing in cell number and size) and morphogenesis (the creation of an organism’s shape, including the organization and the shaping of cells). After explaining what microtubules are and illustrating their arrays with colorful slides, Dr. Lucas talks about some of the larger questions driving her research, such as, “How do microtubules control morphogenesis?”

Request Transcript

Matan Shelomi provides insight into the remarkably complex digestive system of the phasmatodea, an insect also known as the “walking stick.” He has produced an award-winning two-minute film, “Mystery tubes in the stick bug’s gut,” that has circulated widely online. Shelomi explains that this insect eats a diet of leaves, a diet that presents many digestive problems. He has studied how the insect’s physiology has developed to process the leaves, some of which even contain poisons. He has concluded that the walking stick has a digestive system completely unlike that of other insects.

Effects of a Responsive Surrogate on Nursery-Reared Rhesus Macaques

Dr. Rebecca Brunelli

Department of Biological Sciences, California State University, Chico

View Now

Request Transcript

Dr. Rebecca Brunelli developed an interest in animal welfare, particularly the welfare of animals in captivity, while doing research at the Primate Research Center at UC Davis. The center includes a research and breeding colony of over 5,000 monkeys. Most of the infants stay with their mothers after birth, but some are separated due to rejection by their mothers or use in the studies of infants. Dr. Brunelli was concerned with signs of distress of the baby monkey who had been separated from their mothers. She worked on developing surrogates, usually furry objects, with some looking like a stuffed toy animal. Through the surrogates, the young monkeys displayed more positive traits, including playfulness, curiosity, and confidence.

Feeding in Flow: The Impact of Waves on Predator-Prey Interactions in the Rocky Intertidal

Dr. Eve Robinson

University of California, Berkeley

View Now

Request Transcript

A common sight for visitors to the rocky beaches on the Pacific Coast is the large colonies of sea anemones clinging to the rocks. How do these creatures, which look like plants but are really animals, manage to catch the zooplankton that swim by – the prey that the anemone, as predator, must catch in order to survive? In this presentation, Dr. Eve Robinson, currently a California State Sea Grant Fellow, shares the results of her research in both British Columbia and in Sonoma County, California. She explains that many factors impact the capture of prey by anemones, including the type of site, neighboring predators, and the wave/flow environment, including the changing tides.

The Role of MUTYH in Cancer Progression

Dr. Alan Raetz

Lawrence Berkekley Natinal Laboratory

View Now

Request Transcript

Dr. Raetz, a graduate of the CSU, Chico biological sciences master’s degree program, discusses how DNA damage and repair relates to cancer. His primary PhD research at UC Davis was to study these effects in the cells of mammals. Dr. Raetz explains that DNA is constantly being damaged (mutated) and constantly being repaired. The vast majority of the repairs are effective; but improper DNA repair leads to such conditions as cancer and aging.  MutY and MUTYH are enzymes that repair cells.  The loss of MUTHY has been linked to the early stages of a specific form of colorectal cancer.  This approach to cancer research is called the Ocogene Theory of Cancer.

Restoring a Diverse Forest Understory Plant Community with Variable-density thinning

Dr. Eric Knapp

United States Fish & Wildlife Service (USFWS) Pacific Southwest Research Station

View Now

Request Transcript

Dr. Knapp explains the importance of the forest understory – that is, the plants on the forest floor. He explains that the forest overstory and understory are substantially altered from their historic old-growth condition. Much of the change can be attributed to the absence of fire – humans put out fires that used to burn uncontrolled. Dr. Knapp presents two methods of forest thinning; methods which pushed forest stands closer to their historic state. However, long-term effects are still being studied.

Alpine Plants: Their Adaptations & Use as Biological Indicators of Climate Change

Dr. Jim Bishop

California and Nevada Region of the GLORIA project

View Now

Transcript with PowerPoint

 

 

Since 2004, Dr. Bishop has been an active participant in a project called GLORIA (Global Observation Research In Alpine Environments). The program is run completely by volunteers, who monitor plant growth at alpine zones around the world. Alpine zones are defined as areas in high elevations above the upper limit of tree growth, or the tree line. The monitoring is done with two goals: 1) to learn how plants adapt in order to survive in a harsh environment; and 2) to see how plants respond to climate change in that environment. Dr. Bishop examines the factors that limit growth above the tree line, and postulates that if the climate warms, the higher elevations will become more favorable environments and gradually inhabitable by a wider variety of plants.

Presentation Time:  54 minutes

A special message from Dr. Bishop: “Volunteers do much of the field work and are always appreciated.  GLORIA data may be of some use to students and faculty.  For more information please contact Adelia Barber at the address given on our GLORIA California website http://www.gloriacalifornia.org/.”

 

The Genomics of Physiological Resilience in Killifish

Dr. Andrew Whitehead

Department of Environmental Toxicology, University of California, Davis

View Now

Transcript with PowerPoint

Dr. Whitehead studies the resistance and resilience of species to environmental stress exposure; he uses the killifish as his primary lab species. He explains that individuals, populations, and species vary in their sensitivity to stressors. Dr. Whitehead presents as an example dioxin tolerance variations among a variety of fish species.  A key question in his research is “What are the genomic variants that enable resistance and resilience?” In searching for the answer to this question, he explores the consequences of chemical exposure and shrinking habitat on resident species.

Transcript with PowerPoint

The importance of conserving pollinators is underscored by the fact that the value of pollinator-dependent crops in California is $11.7 billion. Most of these crops are pollinated by a single species, the European honey bee. Ms. Guisse points out that the numbers of honey bees have declined precipitously, making conservation and restoration vital to the State’s economy as well as to the environment. She notes that honey bee decline has been caused by disease, pests, pesticides, honey prices, and Colony Collapse disorder. She is working with the Xerces Society to restore natural habitat. Ms. Guisse also outlines other conservation practices that support pollinators, including how to reduce bee poisoning from pesticides.

Transcript with PowerPoint

Dr. Epstein’s job with the State of California is to identify Lepidoptera (moths) in California that threaten the state’s economy, mainly as threats to agriculture. He is on the watch for invasive pests from all over the world as well as domestic species. These invasive moths are often brought into California on trucks, on boats, and on the bottom of bee hive boxes. Scattered through his presentation are some surprising facts about moths; for example, there are 200,000 species of moths and, in the pre-adult stage, they must shed their skin 10 to 12 times in order to grow. He shows brief movies to demonstrate the locomotion of various species and some of the mechanisms they have developed to defend themselves.

Transcript with PowerPoint

PREDICT is a project of the USAID  (United States Agency for International Development). Dr. Goldstein is one of the coordinators for this project, the goal of which is to help governments predict where new, emerging pandemic infections might crop up. The project came out of research regarding humans and avian influenza, when it was recognized that no one was doing research regarding wildlife. Dr. Goldstein is a molecular wildlife biologist and works with a collaboration of non-profit organizations and universities to pre-empt or combat at their source the first stages of the emergence of zoonotic diseases that post a significant threat to public health. Zoonotic diseases are those diseases that can be transmitted between animals and humans.

Transcript with PowerPoint

Dr. Ramsey has been exploring mechanisms that contribute to aging. In this presentation, he shares the results of his work regarding these issues. He explains that, overall, his research indicates that the first part of the question – can calories change the rate of aging – may, indeed be true.  As for dietary fat, the verdict is out. Regarding humans, Dr. Ramsey notes that increased lifespan over the centuries is not from lessening the basic effects of aging specifically, but rather is mostly due to improvements in hygiene and improvements in the treatment of infectious diseases.  It is his hope that a deeper understanding of aging processes will help with medical treatment of the elderly.

The California Phenology Project

Dr. Liz Matthews

Post-Doctoral Scientist, University of California at Santa Barbara

View Now

PowerPoint with Transcript

The subtitle of this presentation is “Linking plant phenology to climate change through Citizen Science.” Phenology is the study of periodic plant and animal life cycle stages and how these are influenced by seasonal and by longer-term variations in climate.  The California Phenology Project began in 2010 and is focused on plants in seven California National Parks. Volunteers help identify and monitor species. Phenology is an indicator of environmental change – for example, over time, for some plant species, the date of the first leaf and/or the date of the first flower is earlier in the spring than 10 or 20 years ago. Dr. Matthews shows how such changes can affect an entire ecosystem.
