Information about my e-books


Here, you can find supporting information for the e-books that I have prepared. The books themselves are published with Leanpub, where they can be downloaded (see my author page). You decide the price: there is a suggested price, but you are also allowed to download them for free, no problem. Preparing these books, the Matlab software, and maintaining this website, is done in my own time. So, the more money I can collect with book sales, the more time I can invest in these activities. You need to create an account at Leanpub, with your email address. The good thing is that I can see how many people have downloaded my books, and you get a message whenever I publish a new version. Furthermore, you can comment on the book at the Leanpub site.

At this moment, the following books are on offer:
  • Making sense of chemical stress. Applications of Dynamic Energy Budget theory in ecotoxicology and stress ecology. By Tjalling Jager. Support page.
  • DEBkiss. A simple framework for animal energy budgets. By Tjalling Jager. Support page.
  • Modelling survival under chemical stress. A comprehenisve guide to the GUTS framework. In preparation (first release expected end of 2017). By Tjalling Jager & Roman Ashauer. Support page.
  • My PhD thesis from 2003 (the unpublished Chapter 2 is a thorough introduction into TK modelling). By Tjalling Jager. Download from Leanpub.
More books might be prepared in the future.

Please do not modify these e-books or post them on another website. Feel free to link to these web pages though, or to Leanpub, which ensures a connection to the latest version.

Why (free) e-books?


First and foremost because I want to make this information available to as broad an audience as possible. Furthermore, an e-book is more environment friendly: you can read it from a pc, e-reader or tablet, or you can print the specific parts you would like to read, and I can easily keep the contents up-to-date. I now publish it with Leanpub, which offers people the option to pay for the book (though they can also set the price to 0$). I get a fair share from the proceedings, I keep all copyrights, and I can update the books whenever I like. It does not get any better!

Why the PDF format?


Because that is easiest to do with LaTeX, and it allows you to print (parts of) it yourself. PDF also offers the possibility to work with hyperlinks in the document, which helps the reader navigate through the text. Let me know if you would like to see a different format (such as a dedicated e-book format). If I receive enough requests, I may be tempted to dive into this matter.

How often do you update the books?


Difficult to say; it also depends on how many people pay for the e-books (I mostly write them in my own time). When I spot clear errors, I will correct them ASAP. Further, I expect to add new literature with some regularity. In any case, I will keep a version log to clarify what changes I made in each new version. The PhD thesis will certainly not be updated anymore.
