Wed. Jan. 25 – Summer fog patterns of Santa Barbara County

Sunrise 3-15-13

During the dry summer months, coastal shrubs in California receive little to no rain. However, shrub-dominated plant communities can be inundated by periodic fog events. I will be sharing my dissertation work examining the patterns of summer fog deposition, chemical make-up of fog and plant uptake of fog water. Come on by and let’s talk fog while reminiscing about those sunny summer months.

Wed. Jan. 11 – Alaska’s salmon and people in the (rapidly changing) 21st century

Elmendorf Salmon Viewing Platform

This talk is an informal sketch of the emergent State of Alaska’s Salmon and People (SASAP) initiative, jointly told by many of the project’s leads. In addition to providing listeners with an understanding of the SASAP process, we aim to provide insights into our own motivations for joining the work, sketches of work in our laboratories, and a general sense of the importance of salmon to the overall health of Alaska.

Measuring the status of fisheries and factors leading to success

This talk will summarize the results to date of our SNAPP group of the same title.  We will summarize the data we have available on the status of fish stocks,  and how they are managed.
We now have reliable data from national and international scientific institutions on stocks constituting over 50% of global fish catch, with Asia south of Japan the major area that is not covered.  We also have less reliable estimates from  statistical models of most fisheries not covered by scientific assessments.  We have also collected data on how fisheries are managed in major fishing countries and international fisheries.  Our best estimates are that globally fish stock abundance has been stable for the last several decades,  but increasing in places were good scientific data are available and likely decreasing where such data is not available.  Our preliminary results suggest that there is not a strong relationship between the intensity of fisheries management and stock status because intensive management seems to result from poor stock status.  If we focus on stocks that are overfished then a clear relationship between intensity of management and stock recovery emerges.
At our current meeting we are asking two key questions.  (1) what factors have led to recovery of overexploited species and (2) Does science advice improve fisheries outcomes.

Using social media to advance your research career

Most of us use social media as an effective way to connect with
friends and family. For academics though, social media can be even
more effective at advancing professional goals. In this roundtable, I
will illustrate the many ways that roundtable participants can use
social media to powerfully further their career objectives. These
objectives include things like: keeping track of the latest
developments in the field, increasing awareness among colleagues of
your research, and furthering outreach goals. I will be focusing on
Twitter, though the principles are roughly the same across social
media platforms. At the end of the roundtable, my intention is that
participants will have gained actionable information about social
media that they can immediately put to work to further career goals.
This roundtable will involve some interactive activities, but
participants will not need to bring computers (or anything else) to
take part in these activities.

Introduction to Jupyter notebooks and quick dive into Python

Presenter: Julien Brun

Jupyter notebooks are a great way to share your data analysis and promote reproducible science.  These interactive notebooks mix executable computer code (e.g. Python, R, Julia, Bash, …) with rich text and data visualizations. Have a look here for some examples: https://nbviewer.jupyter.org. We will use this tool to do a quick dive into Python with specific tips for R users.

Note that the hands-on participation is space-limited and you need to register here. However, everybody is welcome to follow the session in person or remotely. The hands-on participants  will need to bring their laptop to connect to NCEAS’ server, but no specific installation is required.

Plant Community Responses to Global Change Drivers

Global change will alter resources, which are predicted to change the composition and functioning of plant communities. Here, I present the results of several projects studying plant community changes in response to resource manipulations. First, I present data from an experiment at Konza Prairie Biological Station in Manhattan Kansas. In this experiment, nutrient additions (nitrogen and phosphorus) turned the tallgrass prairie from being dominate by C4 grasses to C3 forbs. Next, I detail plant community responses to resource manipulations across ~100 experiments world-wide. This data synthesis found that when 5 factors are simultaneously manipulated, there are drastic changes in the plant community. Additionally, the greater number of factors that are manipulated, the greater the change in productivity. Lastly, I review my current postdoctoral work, focused on developing new ways to study patterns of community change using rank abundance curves.

Carbon Neutrality at University California: The TomKat Project

Abstract

In 2013, University of California President Janet Napolitano announced the UC Carbon Neutrality Initiative, which declares that all ten campuses in the University of California will have zero net emissions by the year 2025. Through a generous donation from the TomKat Foundation and supplemental funding from the University of California Office of the President, two groups of researchers have assembled to help address different facets of this multidimensional initiative. These two teams of the TomKat Project are hosted by the National Center for Ecological Analysis and Synthesis and supported by the Institute for Energy Efficiency at UCSB.

The Exit Strategies for Natural Gas working group is focusing on the challenge of eliminating natural gas emissions from the ten UC campuses and their medical centers. This is made difficult by the lock-in situation that exists at six campuses which rely on cogeneration power plants for heating and power. The Net-Zero Comm Strategy working group will work to develop and test best communication techniques for the University of California to achieve zero net emissions by 2025. This process will involve performing audience research on key stakeholders at the University of California, testing messages, and analyzing barriers to gaining support for the Carbon Neutrality Initiative.

The Day After: Bird Conservation in [Insert President-elect’s name]’s America! [Wed. Nov. 9th]

Come take your mind off the aftermath of the 2016 election by talking about birds, citizen science, and habitat restoration instead. I will present on the work done by the San Francisco Bay Bird Observatory (SFBBO), which is a nonprofit that works on bird conservation science and educational outreach projects. Although we work on many projects, I will primarily discuss our work with the South Bay Salt Pond Restoration Project, a new urban biodiversity project with Google, burrowing owls conservation, and our citizen science projects. SFBBO and many of its partners are always looking for collaborators and new projects so I look forward to any ideas for partnerships and gaps in knowledge.

 

I welcome discussion during roundtable and the following are some of my thoughts, although I welcome other ideas!
  • How to promote more linkages among academics and non-profits (i.e., applied ecology and conservation research!)
  • Working with citizen science derived data and how to get our data into the hands of more people
  • Ways to reach more diverse audiences with indoor and outdoor activities
  • Increasing corporate participation in urban ecology as well as the conservation value of urban greening and restoration

Species interactions as biotic filters of global change [Wed. Oct. 12]

The study of species interactions has greatly improved our appreciation of the importance of network structure for ecological community stability, sensitivity to invasion, and extinction. Because species interactions reflect past evolutionary constraints and niche partitioning within a particular local context, they constitute the underlying fabric of ecosystem dynamics, driving biomass and body size distributions, and ecosystem level processes. Here I propose that beyond being a simple witness of global change, species interactions can actually mediate their effects on population and ecosystem dynamics either locally via bottom-up or top-down mechanisms or regionally via spatial cascade processes. I will present case studies for each scenario and conclude with a discussion of future perspectives and challenges for the use of ecological networks in conservation biology.

Discussion on credit and collaboration in science today [Wed. Oct 5]

This week’s Roundtable will be a community discussion on credit and collaboration in science today, motivated by this recent article in The Chronicle of Higher Education: http://www.chronicle.com/article/The-Changing-Face-of/237451/

Here are a few questions we’ll use to structure the discussion:

Do you agree with the author’s assertion that the drive to apportion credit is hurting the spirit of collaboration in science?

Even if you disagree with the author’s argument, can you see any ways in which more precise accounting for credit in scientific collaboration might impact the spirit of collaboration?

What approaches could be used to help someone on the other side of this issue see and appreciate your point of view?

Please read the article and come to discuss evidence and experience you might have on this interesting and very relevant topic.  Hope you can join us!
