Panel discussion
- Hugh’s question on the usefulness of dynamic vs static models: do we have dynamical systems envy?
- Chris: are temporal dynamics historical artefact, and space the new frontier?
- Hugh: though decision theory is fundamentally temporal. really question of sequential decision vs single decision
- Hugh, on what would be his priority if he had time for new question: Solve the 2 player, 2 step SDP competition closed form.
- Paul: the narrow definitions of “math biology” with 1980s flavor.
- @mathbiopaul: Formulating the hard problems arising in application in an appropriate abstraction that mathematicians will attack.
- Leah raises issue of publishing software and reproducibility
- Julia mentions Environmental modeling and software journal
Notes from some discussions today
Sandy Leibold mentions potential for exploring early warning signals in larch budmoth data: Esper et al. (2007) ,
r citet("10.1111/j.1469 -8137.2009.02825.x").Bill Fagan mentions paper with Eli Holmes on quasi-extinction forecasting Holmes et al. (2007) and an analysis of the GPDD Fagan et al. (2001) as potentially interesting applications for our Bayesian nonparametrics work.
Matt Potts mentions DoD program in Strategic Environmental Research and Development Program (SERDP). E.g. see the current call for New Paradigms for Managing Species and Ecosystems in a Non-Stationary World (pdf)
pdg-control
Trying to understand pattern of increasing ENPV with increasing stochasticity. Despite having the same optimal policy inferred under increasing stochasticity (i.e. still in Reed’s self-sustaining criterion, below \(\sigma_g\) of 0.2 or so) the average over simulated replicates is higher. We don’t seem to obtain the theoretical ENPV, but something less, in either case. See code noise_effects.md.
ropensci
Schema.org defines a vocabulary for datasets (microdata/rdfa)
Rutger gives a one-liner solution for tolweb to nexml using bio-phylo perl library:
perl -MBio::Phylo::IO=parse -e 'print parse->to_xml' format tolweb as_project 1 url 'https://tolweb.org/onlinecontributors/app?service=external&page=xml/TreeStructureService&node_id=52643'Hmm, there’s a journal of Ecological Informatics.
