[ECOLOG-L] Application deadline approaching: Grimm & Railsback individual-based modeling short course
The May 5 application deadline is approaching for Humboldt State's annual individual-based modeling short course, taught by Steve Railsback and Volker Grimm. The course is intended first for faculty interested in teaching individual-based modeling, but we also welcome people interested primarily in research applications. The course is based on "Agent-based and Individual- based Modeling: A Practical Introduction" by Railsback and Grimm: http://www.railsback-grimm-abm-book.com/ . See http://www2.humboldt.edu/ibm/ for information and the very simple application process.
[ECOLOG-L] Humboldt State short course on individual/agent-based modeling, 30 July - 3 August 2018
Steve Railsback, Volker Grimm, and Steve Lytinen will conduct our eighth summer short course on individual-based (agent-based) modeling, July 30 - August 3, 2018, at Humboldt State University. The course is intended primarily for university faculty and instructors interested in teaching their own modeling courses, but we also welcome participants interested mainly in research applications. The course will be based on the textbook "Agent-based and Individual-based Modeling: A Practical Introduction" by Railsback and Grimm: http://www.railsback-grimm-abm-book.com/ . The instructors are the textbook's authors and Steve Lytinen, professor of Computer Science at DePaul University. The course's main goal will be to introduce participants to both the software - NetLogo - and the modeling concepts in the book, to the point that they can then teach themselves and others how to become productive modelers. We will focus especially on developing NetLogo programming skills, via exercises and projects with a high level of instructor interaction. The course will be held at Humboldt State, on northern California's beautiful redwood coast. The fee is expected to be $600, which includes instruction and materials, social events, and lunches. Participants will provide their own transportation to and lodging in Arcata; low-cost campus lodging will be available. Applications are being accepted through May 5th.

[ECOLOG-L] 2017 Dresden summer course in individual-based modeling
The Dresden University of Technology announces their 11th annual summer course in individual/agent-based modeling. The 2017 course will be a non-beginners course, intended primarily for graduate students and researchers who have been developing their own model and seek guidance on finishing, analyzing, and doing science with the model. The instructors--Uta Berger, Volker Grimm, and Steve Railsback--have many years of experience using and teaching individual-based modeling. The overall goal of the course is to guide researchers through the process of completing and publishing research based on individual-based models. We expect participants to have at least a working draft model before the course starts. Instruction will be via lectures, exercises, and independent work under close supervision of the instructors. Topics will include software testing, parameterization, analyzing model sensitivity and robustness, designing simulation experiments, and publishing model-based research. While the instructors are ecologists, participants in any field are welcome. Instruction will use NetLogo software and the textbook of Railsback and Grimm (2012; "Agent-based and individual-based modeling: a practical introduction", Princeton University Press), but modelers using other software platforms will be able to participate fully. The course will be 20-28 July 2017, in a small village outside Dresden (Germany). To provide a high level of instructor interaction, course size is limited to 25 participants. The application period is now open, and closes 28 February.

[ECOLOG-L] 4-Year Researcher in Evolutionary Ecology (Modelling)
The deadline for applications to this position is 27 March. Topic: The research project which the position belongs to (Adapted heuristics and architecture: towards an understanding of personalities and phenotypic diversity), studies the architecture for decisions in animals, and effects of it. The research will focus on adaptive effects of this architecture on individuals, gene pools, and on phenotypic variation in the populations, included personality variation. The project idea is developed for pelagic fish and shall be expanded and utilized in other habitats and for other animals. The project's working method is mathematical modeling. The researcher is expected to take an active role in the activities within the Theoretical Ecology Group. The project is carried out in collaboration with specialists in Bristol, Santa Cruz and Berkeley. The project is led by Jarl Giske (email: jarl.gi...@bio.uib.no) and the workplace will be the Theoretical Ecology Group at the University of Bergen. Application deadline is 27 March 2015.
