As a non-professional, I have a broad interest in different aspects of biology and herpetology. Although my focus lies on snakes, I am fascinated by the physiology of reptiles in general. Biogeography, systematics & nomenclature, ecology, and evolution are the other topics that are of interest. I am working on a book manuscript about the biology of snakes. By doing so and reading lots of great papers, I am getting a broader picture of it all. In short: I’d like to learn everything I can ;)

This was a comment I wrote back in 2009 as response to the Pauly et al. (2009) paper. Although it was accepted by Herpetologica, I withdrawn it from publication for some reasons. Nevertheless, I think it may be worth being read.

The International Code of Zoological Nomenclature (ICZN; hereafter, the Code) governs not only the availability and application of scientific zoological names once they enter the realm of nomenclature but also what is to be considered published work for the purpose of zoological nomenclature. Article 8.1.1 of the Code clearly demands that to be con...

McDiarmid et al. (1999) published the first part of their planned taxonomic catalog of the snakes of the world. Since then, several new python taxa have been described in both the scientific literature and non-peer-reviewed publications. This checklist evaluates the nomenclatural status of the names and discusses the taxonomic status of the new tax...

This study is the first comprehensive systematic study on the python genus Leiopython Hubrecht 1879 native to New Guinea. The taxonomic arrangement recently made is critically reviewed, and proper descriptions for taxa herein recognized as valid are provided. Twenty external morphological characters were recorded from 90 preserved specimens from th...


Question (1)
Some relevant words used in articles of the International Code of Zoological Nomenclature (ICZN, 1999) are not defined by the glossary and it seems that there are different interpretations for them that may differ from common sense.
I'd like to ask how the scientific community defines words like "obtainable" (Art. 8.1.2) or "durable copies" (Art. 8.1.3) in regard to criteria that have to be met for considering a work as published under the provisions of the Code:
8.1. Criteria to be met. A work must satisfy the following criteria:
8.1.1. it must be issued for the purpose of providing a public and permanent scientific record,
8.1.2. it must be obtainable, when first issued, free of charge or by purchase, and
8.1.3. it must have been produced in an edition containing simultaneously obtainable copies by a method that assures numerous identical and durable copies.

Projects (2)
Well, I started this project years back, especially collecting relevant literature and reading and understanding it. Spent quite some time on this yet. The project was stopped by my heart attack early last year. But now I do feel I have to do something different from my actual job again...Going to re-start that book project again, and perhaps as a byproduct there will be one or more review articles on snakes senses and biological rhythms.
