taxizedb arose from pain in using taxize when dealing with large amounts of data in a single request or doing a lot of requests of any data size. taxize works with remote data sources on the web, so there’s a number of issues that can slow the response down: internet speed, server response speed (was a response already cached or not; or do they even use caching), etc.

Garnett et al. recently published a paper in PLoS Biology that starts with the sentence "Lists of species matter": This paper (one of a forthcoming series) is pretty much the kind of paper I try and avoid reading.

These are simply notes to myself about taxonomic classifications in Wikidata. Classifications in Wikidata can be complex and are often not trees. For example, if we trace the parents of the frog family Leptodactylidae back we get a graph like this: Each oval represents a taxon in Wikidata, and each arrow connects a taxon to its parent(s) in Wikidata.

Given my renewed enthusiasm for Wikidata, I'm trying to get my head around the way that Wikidata models biological taxonomy. As a first pass, here's a diagram of the properties linked to a taxonomic name. The model is fairly comprehensive, it includes relationships between names (e.g, basionym, protonym, replacement), between taxa (e.g., parent taxon), and links to the literature.

Our next Community Call, on March 27th, aims to help people learn about using rOpenSci’s R packages to access and analyze taxonomy and biodiversity data, and to recognize the breadth and depth of their applications. We also aim to learn from the discussion how we might improve these tools.

There's a slow-burning discussion on taxonomic concepts on Github that I am half participating in. As seems inevitable in any discussion of taxonomy, there's a lot of floundering about given that there's lots of jargon - much of it used in different ways by different people - and people are coming at the problem from different perspectives. In one sense, taxonomy is pretty straightforward.

Thanks to the second post of the series where we obtained data fromeBird we knowwhat birds were observed in the county of Constance. Now, not allspecies’ names mean a lot to me, and even if they did, there are a lotof them.

taxize was seven years old this last Saturday!What is taxize? taxize is designed around making working with taxonomic names easier - abstracting away the details of what each of 20 or so taxonomic data sources require for a given use case.

What is Taxonomy? Taxonomy in its most general sense is the practice and science of classification. It can refer to many things. You may have heard or used the word taxonomy used to indicate any sort of classification of things, whether it be companies or widgets. Here, we’re talking about biological taxonomy, the science of defining and naming groups of biological organisms.

Following on from adding DNA barcodes to GBIF I've now uploaded a taxonomic classification of DNA barcode BINs (Barcode Index Numbers). Each BIN is a cluster of similar DNA barcodes that is essentially equivalent to a species.
