Of Lice and Birds

About host-parasite coevolution in general with an emphasis on host-parasite cospeciation in lice and birds.

Comparative tests of ectoparasite species richness in seabirds.

This is the first time that I have published in a BMC journal and I have been very impressed with the speed at which it has been published. It went through a tough reviewing process of almost 5 months. The comments made were very useful and detailed but once accepted, it all went very fast. I would definitely recommend publishing with biomed central.

The lice of the Tristan da Cunha Archipelago

Christine Hanel has just published her paper with Ricardo Palma on the lice of Tristan da Cunha Archipelago with detailed information on the hosts and the distribution on the different islands of the Archipelago.

Pectinopygus and Pelecaniforme cospeciation

We have recently published "Multiple Cophylogenetic Analyses Reveal Frequent Cospeciation between Pelecaniform Birds and Pectinopygus Lice." All the additional data for this paper can be obtained from my website, Treebase and GenBank.
Hopefully, this will provide a dataset for future tests of cospeciation methodologies.

Lousebuster

Dale Clayton has invented a huge hair dryer that sucks the life out of head lice. The study shows that it is very effective and significantly reduces the number of lice in 30 to 35 min. No need for those powerful delousing shampoos.

Sharing comparative data


I've recently been trying to gather useful information for comparative analyses in birds and lice. Unfortunately, I have had to follow the tracks of others, repeating their work, simply because most researchers are selfish with their data. The researchers I have contacted have not answered my request for their published comparative datasets. I find this very frustrating. No wonder research in the field of evolutionary ecology is particularly slow. We continuously repeat the work of others instead of building upon it. Wouldn't it be lovely if ecologists were obliged to publish their raw data on the web as is required for other fields of biology like phylogenetics, genomics and proteomics (it is a prerequisite to publication that the sequence data should be online). Why is this not the case for ecologists? Is it because there is no appropriate database? Well, I don't think the infrastructure is needed. Just publishing the data as a text file on the web would be enough.
Today, we even have applications like EditGrid on the web. This provides an ideal solution for gathering ecological data and sharing it. I have been using EditGrid to gather information on various seabirds and I am making it available to the public. The following graph illustrates the variables used and the number of data entries for each variable.
If you believe in open access and have any type of ecological or morphological data for birds that you would like to share with the world, please do get in touch.

Pelecaniform birds and lice

Our article on cospeciation Pectinopygus lice and Pelecaniform birds has been recently accepted for publication in Systematic Biology. It unambiguously support cospeciation between the birds and the lice by using multiple cophylogenetic methods (TreeMap, TreeFitter, ParaFit, Coalescence, ILD) including the calibration of host and parasite phylogenies to provide support for similar timing of speciation in both hosts and parasites.
