ECL 290s. Participatory seminars


Theoretical Models in Metacommunity Ecology. Gillian Bergmann, with Alan Hastings and Marcel Holyoak. Click here for more information.  

CRN: 39751

Time: Wednesdays, 11-11:50am

Location: Remote (Zoom)

Summary: In recent years, there has been increasing interest in understanding the drivers of variation in community composition across spatial scales. Metacommunity ecology, which explicitly accounts for scale, dispersal and environmental heterogeneity, provides a generalized framework for studying this variation (Leibold and Chase, 2018). The explicit consideration of scale in metacommunity theory allows for disentanglement of how local and regional processes contribute to community composition and dynamics (Leibold and Chase, 2018). This seminar will explore the history of modeling within and among the four archetypes of metacommunity ecology, how spatial and temporal scales are accounted for in these models, how empirical data have informed model development, and how these models can be applied in various ecological topics (e.g. community assembly and succession, response to global change and conservation).

Paradigms in Predator-Prey Interactions Across Spatial Scales. Ellie Bolas and Olivia Feldman, with Justine Smith. 

CRN: 39742

Time: Wednesdays at 3:10pm

Location: Remote (Zoom)

Summary: Predator-prey interactions are a fundamental relationship in ecology, with implications for the behavior, habitat use, fitness, and demography of the focal species and for composition and functioning of the ecosystem as a whole. We will examine how predator-prey relationships across taxa (including humans) and in diverse ecosystems vary across spatial scales, with a particular focus on how behavior and space-use are modified by predator-prey interactions. Please see attachment for further information and proposed readings.

ECL 290s. Participatory Seminar - Fall 2020


Fire and biodiversity. Drs. Hugh Safford, with Kyle Lunneberg and John Williams

CRN: 29558

Time: Thursdays, 1 pm

Location: Remote (Zoom)

Summary: Earth is a flammable place, and fire has a long history on earth. The first fossil evidence we have of fire comes from the Late Silurian Period, more than 420 million years ago. Earth is covered by carbon-based vegetation, it supports an oxygen-rich atmosphere, it has many regions where climates are seasonally dry, and there are plenty of ignitions from lightning, volcanic activity, and humans. As a result, many species are adapted to fire in one way or another. Human alterations to disturbance regimes have been a major source of ecosystem degradation on earth, and changes to fire regimes have had especially major impacts on biodiversity and ecosystem composition, structure and function. This seminar will investigate the roles that fire regimes, and changes to fire regimes, play in driving biodiversity patterns on earth. Participants are required to attend all sessions (absences must be cleared with the organizers) and to give a 20 min presentation on a relevant subject of their choice (to be cleared by the seminar organizers). Subjects can focus on ecosystems, species, taxonomic groups, geographic regions, specific fire regimes, and so on. 

The seminar will be held virtually. The 10 seminar meetings will include three to four guest speakers, and approximately six sessions dedicated to seminar participant presentations (two presentations per session).

Plant-herbivore physiology and foraging. Eric Tymstra,, with Maria Ospina,, and Dr. Gail Patricelli,

CRN: 29561

Time: Mondays, 5-6:30 pm

Location: Remote (Zoom)

Summary: Explore topics on plant physiology and herbivore foraging behavior to potentially (depending on interest) work towards a review paper focusing on the interactions between disturbance, plant and herbivore physiology, and foraging. The course will explore these interactions both as a broad topic and in the context of climate change. Click here for more information.

How do fuels affect fire behavior, and how does fire affect fuels? Derek Young, and Ashley Grupenhoff,

CRN: 29559

Time: Mondays, 1-2 pm

Location: Remote (Zoom)

Summary: Main guiding question: How do fuels affect fire behavior? We will stick to the topic of fuels to explore fire behavior models, so we’ll emphasize how models are driven by fuels (as opposed to how they work in general). Click here for more information.

Critical Issues in the Conservation Ecology of Bats. Leila Harris,, with Mary Clapp,, and Dr. Douglas A. Kelt.

CRN: 29619

Time: TBD - based on participant availability

Location: Remote (Zoom)

Summary: This seminar will focus on issues in ecological research and management of North American insectivorous bats. Click here for more information

Because bats intersect wetland and terrestrial systems, are highly mobile, and have cryptic spatial and temporal patterns, they present unique challenges for researchers and managers.  This seminar will use a format of participant presentations, literature discussion, data workshops, case studies, and guest lectures to better understand and tackle these challenges.

Specific topics will be guided by participant interest. Examples of topics include bats as the vehicle for:

·       Identifying meaningful spatial scales for research and management of highly mobile taxa

·       Evaluating anthropogenic impacts and designing mitigation approaches when dealing with data-deficient species

·       Examining the assumptions behind ecological interpretations of bioacoustic data

·       Understanding zoonosis and reverse zoonosis: fact v. fallacy and where we are in the state of the science

·       Exploring the effectiveness of adaptive management as applied to bats

·       Assessing relative contributions of aquatic and terrestrial systems to foraging budgets

To receive credit, participants will select material and lead a discussion on one course topic of their choice, and prepare one 20-minute presentation. 

Principles and Applications in Freshwater Ecology. Rachelle Tallman, rltallman@ucdavis.eduand Mattea Berglund, mkberglund@ucdavis.eduwith Dr. Robert Lusardi.

CRN: 29623

Time: Fridays, 12:10-1 pm

Location: Remote (Zoom)

Summary: Freshwater is essential to both ecological and human systems, and freshwater ecosystems are widely impacted by anthropogenic change. This seminar will explore seminal papers in freshwater ecology and their applications to management and conservation. Potential topics include flow regimes and environmental flows, aquatic food webs, nutrient cycling and subsidies, and restoration. A schedule of suggested papers will be provided, with the option for students to select different papers if they choose. Each student will lead a class session. Click for more information here.

Phylogenetic Methods and Principles. Reed Kenny,, and Daniel Potter, Click here for more information.

CRN: 20864

Time: Mondays, 2:10-3pm

Location: Remote (Zoom)

Summary: The goal of this course is to explore current topics in the principles and methods of phylogenetics in a participatory seminar format. This seminar should give students a good grounding in the most current methodologies in phylogenetics, but it is unlikely that we will dig into the minutiae of applying any particular method. Rather this should enable students to choose the most appropriate methods for a variety of applications. 

Identifying and addressing ecological knowledge gaps in managing California’s low-elevation ecosystems to minimize the impacts of wildfire, and enhance post-fire recovery. Valerie Eviner,, and Sarah Gaffney, Click here for more information.

CRN: 20905

Time: Tuesdays, 3:10-4pm

Location: Remote (Zoom)

Summary: While there has been substantial research in California forests on management to decrease wildfire impacts and enhance post-wildfire recovery, a lot less is known about pre- and post-wildfire management in California’s lower elevation ecosystems, including grasslands, oak woodlands and chaparral. The purpose of this seminar is to engage with diverse land managers to identify both the knowledge gaps that limit their ability to manage with increasing wildfire, and the knowledge they have gained on this subject through their experiences.

Quantitative Methods for Ecosystem-Based Management. Andrea Odell, Nima Farchadi, and Jack Buckner with Kiva Oken, kloken@ucdavis.eduClick here for more information.  

CRN: 45603

Time: Fridays, 9-9:50am

Location: Remote (Zoom)

Summary: Ecosystem-based management (EBM) is a paradigm in conservation and natural resource management that seeks to improve outcomes by applying a more holistic approach and leveraging more detailed ecological, social, and economic information. These efforts can be aided by quantitative tools designed to better describe key ecological, social, and economic processes acting on an ecosystem. In the context of ecological processes, these tools can describe species interactions, the effects of disturbance and abiotic conditions on species abundance and community composition, and the joint distribution of species and their habitats. 

A Critical Appraisal of The Dreamt Land. Kristin Dobbin, Alexandra Gulachenski, and Krista Marshall, with Tyler Scott, Click here for more information.  

CRN: 45604

Time: Mondays, 1:10-2pm

Location: Remote (Zoom)

Summary: Dreamt Land: Chasing Water and Dust Across California by prominent California author/journalist Mark Arax was published in 2019 and quickly became a national bestseller. The book uses reporting, historical accounts, and storytelling to explore the roots of water use in the Central Valley and how this complex system touches the lives of those who work and live in one of California’s most productive agricultural regions. In this seminar we will use this book as a starting point to broaden and diversify narratives about the Central Valley.

Dietary Metabarcoding. Ben Sacks, Click here for more information.

CRN: 20894

Time: Thursdays, 12:10-2pm  (Jan 7-Mar 11).
