Oxygen & the Ecology of Upwelling Margins In a Changing Ocean - An MEB Thursday Noon Seminar

UC San Diego

Sept. 25 @ 12 PM
AHF Torrey Webb Room

Persistent hypoxia (low oxygen) alters both structural and functional aspects of benthic communities, with major consequences for ecosystems services at shallow and bathyal depths. Continental margins subject to upwelling exhibit strong gradients in oxygen, CO2 and temperature, and can serve as ideal natural laboratories for the study of environmental stressors.  Several decades of study of open ocean oxygen minimum zones (OMZs) reveal massive influence of oxygen on benthic abundance, biomass, body size, species composition, species distributions, lifestyles and biodiversity. Differing low-oxygen sensitivities exist among taxa as a function of phylogeny, body size and exposure history, leading to very different oxygen thresholds and responses. Functional consequences of the structural changes include shifts in trophic pathways and efficiency, enhanced roles for chemosynthesis, altered predator and prey encounter dynamics, changing pathways of carbon processing and burial, reduced ecosystem resilience, connectivity and a host of other emergent properties.

As a result of rising CO2 in the atmosphere, upwelling margins are experiencing increased coastal hypoxia and hypercapnia (high CO2).  The strong natural variability of O2 and CO2 on multiple time scales poses a challenge for understanding population and ecosystem responses to OMZ expansion. Approaches for resolving the effects of declining oxygen and pH on margin ecosystems and their services include the use of natural environmental gradients, laboratory manipulations, geochemical proxies and time series data. Scientists today are faced with a need to integrate the influence of natural variability, climate-driven change and direct human activities in management of continental margin ecosystems and resources. The US West coast is increasingly becoming a testbed for ways to address this challenge.

ChIP-seq: unleashing its full potential through data integration - Computational Biology Colloquium

Computational Biology Colloquium

“ChIP-seq: unleashing its full potential through data integration”

One major goal of functional genomics is to comprehensively characterize the regulatory circuitry behind coordinated spatial and temporal gene activities. With the ability to map genome-wide transcription factor binding sites and histone modifications, ChIP-seq has quickly become an indispensable tool for studying gene regulation. Despite its unprecedented power, a number of challenges must be overcome before one can take full advantage of this high-throughput technology. First, ChIP-seq is increasingly used for analyzing dynamic changes of regulatory circuitry across different biological contexts (i.e., different cell types, time points, etc.). The conventional methods for analyzing data for one protein in one cell type cannot meet the emerging needs for characterizing quantitative and synergistic changes of DNA binding of multiple proteins between different conditions. New methods are required for dealing with the exponentially growing number of multi-protein combinatorial patterns, and for evaluating the statistical significance given the background biological and technical variation. Second, ChIP-seq is high-throughput with respect to analyzing the whole genome, but low-throughput with respect to analyzing gene regulation in a large number of biological contexts. New strategies need to be developed to better utilize ChIP-seq data originally collected from one biological system to gain insight into gene regulation in other biological systems or diseases. Third, ChIP-seq data also contain information on allele-specific binding (ASB). However, applying ChIP-seq to study ASB often suffers from low statistical power due to the limited number of reads mapped to heterozygote SNPs. In this talk, I will demonstrate that the problems above may be approached computationally by developing new statistical methods for jointly analyzing multiple ChIP-seq datasets and methods for integrating ChIP-seq data with enormous amounts of gene expression data in Gene Expression Omnibus (GEO).

From Correlative to 3D – Recent Advances in Bio Scanning Electron Microscopy
September 25,12.30

Biological structures, such as organelles, bacteria, somatic cell layers, tissues and model organisms are inherently three-dimensional (3D) and technologies that aid visualization and analysis of 3D biological samples is growing rapidly. Specifically, recent developments in Bio Scanning Electron Microscopy allow high-resolution imaging of samples embedded in resin, then physically sliced and the resulting sections collected in a serial ribbon on tape, glass slide or slotted grid. Each approach has unique benefits and allows access to antibody and other affinity probes for interrogation of specific molecules.  Alternatively, 3D tomograms of entire sliced volumes can be automated with serial block face imaging, where an ultramicrotome is either integrated directly into the electron microscope chamber or a focused ion beam (FIB) is used to mill away the specimen. Block face images have significantly lower distortions associated with material removal than the compression seen in thin sections, thus final 3D EM reconstructions from this approach align closely with the 3D LM volume image. Furthermore, a far greater understanding of the structure-function relationship in cells and tissues is now achievable via high resolution correlation of chemical markers and structural components in both 2D and 3D dimension. This presentation will focus on contemporary methods and probes, methods and workflow for array tomography, serial block face imaging and correlative light and electron microscopy (CLEM) and demonstrate with practical examples how these tools can provide  powerful and novel  insights into biological problems.

Tropical forests in the Anthropocene - Special Seminar

Please consider attending the following special seminar. It should be an overview from a leading forest ecologist that would appeal to anyone with a general interest in historical and contemporary environmental change (from megafaunal extinctions to climate change).

Tropical forests in the Anthropocene

Abstract: The Anthropocene is characterized as an epoch when human influence has begun to fundamentally alter many aspects of the Earth system, and many of the planet¹s biomes. Here I review and synthesize our understanding of Anthropocene change in tropical forests, in the context of the long-term environmental history of humanity in the tropics from the Pleistocene to the present. I explore possible reactions and responses to change in the tropics. Key facets of Anthropocene change in tropical include deforestation, timber and wood extraction, the loss of fauna that maintain critical ecological connections, the spread of fire, landscape fragmentation and the spread of second-growth forests, invasion and pathogen spread, and increasing CO2 and climate change. The patterns of change are spatially heterogeneous, often have strong interactions among them, can have both large-scale and remote effects and play out through ecological cascades over long time scales. As a consequence, most tropical forests are on a trajectory to becoming altered ecosystems, and many are becoming novel ecosystems. I explore strategies for shaping the transition of tropical forests through the early Anthropocene, as well as highlight opportunities and challenges for the tropical forest science and conservation community.
