The Spring 2016 Biology Seminar Series continues with Dr. Erin Brinton's talk: Drowning corn: Molecular responses of Zea mays ssp. mays to flooding

Flooding is the second leading cause of corn (Zea mays ssp. mays) crop loss in the United States and is further exacerbated by global climate change. While plants require water for growth, too much can impart multiple stresses, one of the greatest of which is limited oxygen availability due to decreased gas diffusion. This limits aerobic respiration, which when coupled with reduced photosynthesis, promotes unchecked carbohydrate consumption to offset inefficient ATP production. Some of the earliest studies of plant low-oxygen responses were undertaken in corn and included observations of changes occurring at multiple levels of gene regulation, from gene transcription through mRNA translation. However, very little has been reported at the genome scale of the responses of corn to...

The Spring 2016 Biology Seminar Series continues with Dr. Gargi Kulkarni's talk: Bacterial hopanoids and their role in plant symbiosis

Symbiosis means "living together”, i.e. when two organisms live in close association to benefit each other. For instance, soil bacteria called rhizobia, like Bradyrhizobium diazoefficiens, can enter into symbiosis with leguminous plants, like soybean. In this relationship, the plants provide the bacteria with a food source and the bacteria provide the plant with the essential nutrient nitrogen. Our recent research suggests that hopanoids or cholesterol-like lipids produced by rhizobia are required for proper growth of bacteria in both free-living soil and symbiotic plant states. More research into how hopanoids help bacteria to survive may aid in engineering of more robust agricultural strains that are resistant to harsher climates.

Participate in the BioBlitz@Oxy event on April 2, 2016

The Bioblitz@Oxy is a citizen science event to document the biodiversity of Occidental College. During this one day event, we will identify as many species as possible on the Occidental College campus. These data will provide baseline knowledge about local biodiversity so we can measure how these species respond to future environmental changes.

To sign up and view more information, please visit the BioBlitz website: http://biodiversity.oxycreates.org/

The 2016 Spring Biology Seminar Series continues with Miguel Ordeñana's talk: #NatureinLA: Documenting L.A. Wildlife Using Cameras, Citizen Science, and Social Media

I will be talking about urban wildlife research projects that I have been involved in along the urban edge and core of the Los Angeles area. I will discuss how technology and citizen science has provided new opportunities to conduct research on elusive species in understudied ecosystems at new scales. Citizen science has also provided scientists and non-scientists with unprecedented access to extremely urban ecosystems made up of primarily private property. Together, citizen science, social media and new advancements in technology offer a bright future for urban wildlife research and the inclusion of non-scientists in the scientific process.
