Taking a Long Look at Lakes

Date: Monday, 6 June 2016   Time: 16:15 - 17:30
Location: Sweeney Ballroom E-F

Speaker: Emily Stanley, University of Wisconsin-Madison, Center for Limnology, Madison, Wisconsin, USA

Presentation Description: In an era of increasing human influence and sometimes slow and sometimes rapid environmental change, lakes have proven to be excellent study systems for observing and understanding temporal dynamics over multiple time scales. Maintaining long-term data sets comes with a variety of challenges, but the value of the investment becomes increasingly apparent as these records lengthen. I will provide several examples of environmental changes revealed by long-term data sets from the North Temperate Lakes Long-Term Ecological Research site and from other long-term lake studies to demonstrate the diversity of types, patterns, and rates of change- and thus to highlight the value of these records for understanding basic ecological phenomena as well as lake responses to human activities.

Metabolic Signatures of Streams and Rivers

Date: Tuesday, 7 June 2016   Time: 16:15 - 17:30
Location: Sweeney Ballroom E-F

Speaker: Bob Hall, Professor, Department of Zoology and Physiology, University of Wyoming, Laramie, Wyoming, USA

Presentation Description: Metabolism of streams and rivers in part controls the degree to which the process downstream transport of organic carbon. Additionally primary production supports a large fraction of animal production in rivers. Long term oxygen monitoring coupled with new statistical modeling methods enables conversion of these data into time series of gross primary production (GPP) and ecosystem respiration (ER), with the outcome of many more long time series of metabolism than currently exist. My presentation will address how to ecologically interpret these metabolism time series and show how we can use them to address questions of C cycling in rivers and assess human impacts to rivers.

Biographical Information: Bob Hall is a limnologist at University of Wyoming where he started in 1998. Since graduate school at University of Georgia he has been interested in stream carbon cycling and food webs, but with a career trajectory of studying ever larger rivers. Current work links geomorphology to stream metabolism and nitrogen cycling, statistical analyses of river metabolism, isotope tracers, and DOC dynamics in streams.

The Good, the Bad and the Ugly: Understanding Evolution with Multiple Environmental Drivers

Date: Wednesday, 8 June 2016   Time: 11:00 - 12:30
Location: Sweeney Ballroom E-F

Speaker: Sinead Collins, Royal Society University Research Fellow, University of Edinburgh, Ashworth Laboratories, Edinburgh, United Kingdom

Presentation Description: Environmental changes seldom occur alone, and while evolutionary theory tends to focus on cases where the environment worsens from the point of view of organisms, there are many cases where the environment also improves organismal fitness. Dr. Collins will discuss recent experiments that deal with limits to evolution under environmental enrichment, as well as empirical and theoretical results for understanding how evolution in the presence of several drivers differs from evolution in response to single environmental changes.

Biographical Information: Sinead Collins has been a Royal Society University Research Fellow in the Institute of Evolutionary Biology at the University of Edinburgh since 2010. This is her second fellowship at the University of Edinburgh, with the first being a NERC Research Fellow. After receiving her Ph.D. at McGill University in Montréal, Québec, Canada, Dr. Collins was a Postdoctoral Fellow at the Max Planck Institute for Plant Breeding in Cologne, Germany. Her research focuses on building the theory needed to predict the evolutionary potential of microbial populations.

Resource and Consumer Control of Cross-habitat Trophic Interactions in Shallow Lakes

Date: Thursday, 9 June 2016   Time: 16:15 - 17:30
Location: Sweeney Ballroom E-F

Speaker: Sebastian Diehl, Professor, University of Umeå, Department of Ecology and Environmental Science, Umeå, Sweden

Presentation Description: Dr. Sebastian Diehl presents a lake ecosystem model where producers and grazers in benthic and pelagic habitats are coupled through carnivore movement and fluxes of resources (light, nutrients). This system exhibits an intriguing mix of top-down and bottom-up regulation. Within each habitat, primary production is top-down controlled by carnivores, but the cross-habitat interaction is driven from the bottom-up by spatially asymmetric resource competition. Producers mutually inhibit fluxes of the resources that most limit production in the other habitat: pelagic producers shade out light and benthic producers intercept sediment nutrients. The resulting positive feedbacks cause abrupt transitions between dominance of benthic vs. pelagic primary and secondary production along environmental gradients. Model predictions are largely congruent with data from unproductive lakes covering a wide gradient of colored dissolved organic matter (cDOM). Notably, the model correctly predicts a negative correlation of pelagic nutrients with primary and fish production, the underlying mechanism being that cDOM-shading suppresses primary production and releases nutrient transport from the sediment to the pelagic habitat.

Biographical Information: Dr. Diehl is a Professor of Ecology at Umeå University. He studied at the Universities of Constance, Göttingen and Lund, and holds a Ph.D. in Animal Ecology from Umeå University. He was a postdoc at the University of California at Santa Barbara and a Professor of Aquatic Ecology at the University of Munich before returning to Umeå in 2009. His research focuses on understanding how environmental factors, organismal traits, and the presence/absence of particular species or functional groups drive and constrain consumer-resource interactions and the resulting community and ecosystem dynamics. He frequently translates assumptions into dynamical models and uses numerical and analytical tools to derive qualitative and quantitative expectations that are subsequently tested with experiments and comparative studies.

Carbon, Carbon, Carbon, and More Carbon

Date: Friday, 10 June 2016   Time: 16:15 - 17:30
Location: Sweeney Ballroom E-F

Speaker: Paul del Giorgio, Professor, Department of Biological Sciences, University of Québec at Montréal, Montréal, Québec, Canada

Presentation Description: There is a growing realization that inland waters are major contributors to the global C balance, as transporters of material from land to the oceans, and also as sites for intense C processing, storage and emission to the atmosphere. This is an area of extremely active research and debate, clearly evidenced by the multiple sessions that in one way or another touch upon C-related issues in this ASLO meeting in Santa Fe. This talk will include an outline of some of the major questions concerning C and greenhouse gas dynamics in inland waters that are the current focus of attention of the community. The presentation has some examples drawn from the work by Dr. del Giorgio’s group, as well as an attempt to summarize and integrate some of the developments and highlights that will be presented in the various C-centric sessions during this ASLO meeting. The talk is addressed to the less carbonaceous audience to provide the broader ASLO community with an overview of this issue of global importance.

Biographical Information: Paul del Giorgio is originally from Argentina. He carried out his undergraduate studies in biology and ecology at the Universidad de Buenos Aires, and then moved on to McGill University in Montréal, Québec, Canada, where he completed a Ph.D. exploring the patterns of metabolism and carbon cycling in lakes. He later expanded these interests into the ecology of aquatic microbes and their role in the functioning of freshwater and marine ecosystems. In recent years, his group has increasingly focused on carbon and greenhouse dynamics in boreal surface waters, including rivers, lakes and wetlands, their connections to the terrestrial landscape, and the role that these aquatic ecosystems play in regional and global C budgets. His group is also exploring the large scale biogeography of freshwater bacterioplankton, and the interactions between microbes and organic matter across the boreal waterscape. Paul is currently professor at the University of Quebec at Montreal (Québec, Canada), where he also holds the NSERC Industrial Research Chair in Carbon Biogeochemistry in Boreal Aquatic Systems (CarBBAS Chair).
