PalEON at ESA and JSM 2015

Post by Jody Peters, PalEON Program Manager

Next week is a big week for PalEON at two meetings, the 100th annual meeting of the Ecological Society of America (ESA) in Baltimore, Maryland, August 9-14, and the Joint Statistical Meetings (JSM) in Seattle, Washington, August 8-13.

From the contingent of PalEON-ites at JSM, Colorado State graduate student, John Tipton will be giving both an invited talk and an invited poster on “A multi-scale reconstruction of bivariate paleoclimate from tree rings widths using a biologically motivated growth model.”
The poster is hosted by STATMOS from 9:30-10:15 on Sunday, August 9 and the talk is an invited ASA ENVR Student Paper Awards session from 8:30-10:20 on Tuesday, August 11.

We also have a large number of PalEON-ites that will be going to ESA. Below is the schedule of PalEON talks and posters.

It is going to be a great week of sharing the work PalEON has been doing!

PalEON Sessions at AGU, December 15-19, 2014

FM14-logo-483px

We have a number of PalEONistas leading, co-leading, or giving invited talks for AGU sessions that revolve around topics central to PalEON.  If you are going to the American Geophysical Union conference in December and these sessions are of interest to you, be sure to submit your abstract by Wednesday, August 6!

Sessions

1. Finding Signal in the Noise: Dealing with Multiple Sources of Uncertainty in Paleoclimate and Paleoecology, Session ID: 3722 

The session is sponsored by Paleoceanography and Paleoclimatology and co-sponsored by Biogeosciences,  Global Environmental Change, and Nonlinear Geophysics.

Paleoclimatic and paleoecological proxies contain useful signals of past environmental state and variability that are confounded by multiple forms of uncertainty. Identifying meaningful signals and rigorously quantifying the multiple sources of uncertainty is essential to making inferences about past environments and applying these inferences to validate or improve earth system models or to inform decision-makers. Uncertainty can arise from multiple sources including inexact chronologies, unrepresented processes, uncertainties in the mechanisms that sense and archive past environmental change, and our capacity to describe these processes mathematically. In this session we will explore advances in disentangling this complexity via the use of mechanistic forward models, hierarchical statistical models, and other techniques to make robust inferences about past environments with well-quantified uncertainties.

PalEONistas involved: Jack Williams, Connor Nolan, Andria Dawson, John Tipton

2. Constraining Ecosystem Carbon Uptake and Long Term Storage Using Models and Data, Session ID: 2624

This session will focus on both short and long term processes with controlling ecosystem carbon uptake and storage using both modeling and observational approaches. Find more details HERE.

PalEONistas involved: Dave Moore, Valerie Trouet, Mike Dietze

3. Ecological Disturbance: Observing and Predicting Disturbance Impacts, Session ID: 2482

This session focuses on studies that address the effects of ecological disturbance on carbon, water, and nutrient dynamics, as well as methods for understanding non-equilibrium conditions. Find more details HERE.

PalEONistas involved: Jaclyn Hatala Matthes, Dave Moore, Mike Dietze

4. Phenology, Session ID: 3265

We encourage the submission of abstracts that address topics including phenological modeling, scaling from organisms to ecosystems, fusion of models and data, ecologicalforecasting, relationships between phenology and ecosystem processes and services, and the role of phenology in policy decision-making. Find more details HERE.

PalEONistas involved: Dave Moore

5. Inter-site Syntheses to Explore the Biophysical Controls on Ecosystem Mass and Energy Cycling, Session ID: 3725

The session is sponsored by Biogeosciences and co-sponsored by Global Environmental Change and Hydrology.

Data syntheses across a small number of geographically- or ecologically-similar research sites, or ‘micro-network’, can be very useful for exploring the response of ecosystem mass and energy cycling to a constrained set of biophysical driving variables. Thus, micro-network syntheses represent an important bridge between studies focused on hypothesis testing and model development at the site level, and the upscaling of those results to regional and continental landscapes characterized by wide gradients in climate and land cover regimes.  In this session, we welcome studies focused on cross-site data syntheses from a small number (2-7) of field sites to better understand how ecosystem carbon, water, or energy fluxes respond to meteorological drivers, edaphic conditions, and/or land cover change.  We invite contributions that draw from a range of leaf-level, tree-level, plot-level, and/or ecosystem-scale eco-physicological data.

PalEONistas involved: Neil Pederson (with many PalEONista co-authors)

Simon Goring talks historic vegetation at IBS 2013

PalEON postdoc Simon Goring recently presented his work with historic vegetation data in the US Midwest at the International Biogeography Society 2013 meeting in Miami, Florida.  His talk, “Estimating pre-settlement vegetation in the American Midwest: Exploring climate relationships and links to proxy data for robust data assimilation,” builds on Simon’s work to generate spatial data layers providing settlement-era forest composition, density, and biomass estimates  derived from US Public Land Survey data from the 1800’s.  You can check out Simon’s thoughts on the IBS conference on his blog, Down with Time, or view slides from his presentation on figshare here.
