Acaba de salir la segunda edición del Compendio Global de Malezas (A Global Compendium of Weeds) de Rod Randall de Australia. Es un listado de las malezas reportados a nivel mundial, con algunas otras indicaciones y fuentes.
|Un cultivo de calabaza en Sudáfrica, con malezas que provienen en su mayoría de Mesoamérica. Agosto de 2009, cerca de Komatipoort.|
Se añadieron más de 11,000 especies, comparado con la primera edición - ahora incluye alrededor 33,000 especies, o sea, más que el total de especies estimadas para México. ¡Y está disponible en la red! Pero cuidado: son más de 1000 páginas en pdf, y tarda bajarlo.

Dice el autor en un correo electrónico a varias listas de discusión:
It doesn’t seem like its been ten years but in 2002 the original A Global Compendium of Weeds was published. Of course I’ve not been sitting around referring to the same text all those years. I’ve continued to collect weed data and a few months ago it seemed about the right time to publish again. In 2002 I remember saying something like “a second edition was decades away”....
However thanks to a radical reworking of the underlying database by Philip Thomas from HEAR in the early norties publication this time around was a relatively painless, and quick, exercise.
This edition is in a similar format, albeit not as pretty as Rob and Fiona Richardson’s (original editors and publishers), but it looks and works in a similar manner. And yes it does have some differences brought about by my experience with the first compendium. Hopefully for the better.
Firstly there is more detail as to what weed status has been applied by which reference and the extensive index of synonyms and common names is gone. I decided to only list those synonyms that are also mentioned in the text so no matter what name you look up you should also be directed to the current name and any other synonyms listed in the book, without the use of an index. Common names, well they just take up space and added little real value.
As a database sourced document I cannot be certain that every entry is accurate but I spend crazy amounts of time working on the database as part of my everyday job and constantly update taxonomy and references on a daily basis, however there is bound to be errors and omissions and your welcome to send me your suggestions. I still get emails today about the first edition and every single communication is considered and responded to and I thank you one and all for taking the time to send those emails.
The bottom line, this edition is just over 200 pages longer than the first (now 1115 pages), but there are over 12,000 additional names listed (33,000+), and more than 1000 new references.
And I’ve left the best bit for last..... its free. Yes, free. You can download the pdf from the link below.
If you wish print it out, you’ll need a good laser printer that can do double sided printing and then find someone willing to bind 1100 loose leaf pages but I find its quicker and simpler to search as a pdf document, far faster even than as a word document.
And of course your feedback is still most welcome.
