3-YEAR FUNDED PhD POSITION ON EVOLUTIONARY GENOMICS TITLE: How the loss of genes has shaped the genome as we know it SUPERVISOR: Antonio Marco ORGANIZATION: University of Essex LOCATION: Colchester, United Kingdom DEADLINE: April 30th, 2014 DESCRIPTION: Genomes are the product of a long evolutionary process. Many genes have multiple copies, reflecting the importance of gene duplication during genome evolution. The duplication of genes with regulatory functions has been associate with the development of novel functions. However, there is strong evidence that the loss of gene functions has also influenced the evolution of species. Gene loss is often associated with redundant functions, but the loss of non-redundant regulatory genes also happens with relative frequency. In recent years, the characterization of novel types of regulatory genes, such as microRNAs or long-non-coding RNAs, showed that gene loss is much more important that previously thought. Nevertheless, gene loss as a driving evolutionary force has not been systematically explored. This project aims to understand how gene losses have shaped genomes. A PhD student will compare the genomes of related species and characterize which genes have been lost in specific lineages. The work will focus in transcription factors as well as in other regulatory genes such as microRNAs. By analysing the function, evolutionary age and regulatory connections of lost genes, we will be able to generate a model of genome evolution by gene loss. The candidate will be trained in computational biology / bioinformatics, with a focus on evolutionary genetics and comparative genomics. No prior knowledge of computer programming is required, but the candidate will have the chance to learn one programming language and state-of-the-art computational approaches. Depending on the interest of the student, the project may also involve molecular genetics in Drosophila melanogaster.

A new specimen of Manchurochelys manchoukuoensis from the Early Cretaceous Jehol Biota of Chifeng, Inner Mongolia, China and the phylogeny of Cretaceous basal eucryptodiran turtles
Background: Manchurochelys manchoukuoensis is an emblematic turtle from the Cretaceous Yixian Formation of Liaoning, China, a geological rock unit that is famous for yielding perfectly preserved skeletons of fossil vertebrates, including that of feathered dinosaurs. Manchurochelys manchoukuoensis was one of the first vertebrates described from this fauna, also known as the Jehol Biota. The holotype was lost during World War II and only one additional specimen has been described since. Manchurochelys manchoukuoensis is a critical taxon for unraveling the phylogenetic relationships of Cretaceous pancryptodires from Asia, a group that is considered to be of key importance for the origin of crown-group hidden-neck turtles (Cryptodira). Results: A new specimen of Manchurochelys manchoukuoensis is described here from the Jiufotang Formation of Qilinshan, Chifeng, Inner Mongolia, China. This is the third specimen described and expands the range of this taxon from the Yixian Formation of the Fuxin-Yixian Basin in Liaoning to the Jiufotang Formation of the Chifeng-Yuanbaoshan Basin. A possible temporal extension of the range is less certain. The new finding adds to our understanding of the morphology of this taxon and invites a thorough revision of the phylogeny of Macrobaenidae, Sinemydidae, and closely allied forms. Conclusions: Our comprehensive phylogenetic analyses of Cretaceous Asian pancryptodires yielded two main competing hypotheses: in the first these taxa form a paraphyletic grade, whereas in the second they form a monophyletic clade. The inclusion of problematic tree changing taxa, such as Panpleurodires (stem + crown side-neck turtles) has a major influence on the phylogenetic relationships of Sinemydidae and closely allied forms. Manchurochelys manchoukuoensis nests within Sinemydidae together with Sinemys spp. and Dracochelys bicuspis in the majority of our analyses.

Dear babblers, in the past I followed the "total evidence" approach quite doubtlessly, especially when only DNA regions of one genome type (cp, n, mt) were involed. I merely checked if the (good supported) backbone nodes in all trees from individual markers agreed. They mostly did, so I didn't bother any further and created the supermatrix with respective partitioning.
My question is: Is there any standard procedure or common practice I missed, to decide on a quantitative basis if one is allowed to combine the data sets?
I found hints to a couple of tools that should provide such tests [e.g. concaterpillar - couldn't make it run with recent RAxML and is only for amino acid data(?); arn - a package from Farris (yes, THE Farris), which I couldn't locate], but none of them seemed to be working for me.
I then calculated Robinson Foulds distances between the individual trees and the tree from the supermatrix, but I am unsure what distance value should be considered as a threshold (if this is at all a good way to go for my aim).
Please let me know if you have hints in this respect, especially some automizable thing (in R?) would be nice.
PhD thesis unknown to me, which does Bayesian inference of a tree of cells, as well as many other things
Erick Matsen wrote:
The thesis is interesting. It's quite ambitious: in one chapter he sets up a Bayesian inference algorithm for a tree of cells (cc @mathmomike) that explicitly models sequencing error. On the other hand, I can't see how he got any of this to work efficiently for the sizes of data sets discussed, and his software, called ImmuniTree, is not to be found on the web.
@jeetsukumaran and others may know this fellow from his Genovo de novo assembly software for mixed populations.
Following on from the previous post Rethinking annotating biodiversity data, here are some more thoughts on annotating biodiversity data.
Annotations as sticky notes
I get the sense that most people think of annotations as "sticky notes" that someone puts on data. In other words, the data is owned by somebody, and anyone who isn't the owner gets to make comments, which the owner is free to use or ignore as they see fit. With this model, the focus is on how the owner deals with the annotations, and how they manage the fact that their data may have changed since the annotations were made.
This model has limitations. For a start, it privileges the "owner", and puts annotators at their mercy. For example, I posted an issue regarding a record in the Museum of Comparative Zoology Herpetology database (see https://github.com/mcz-vertnet/mcz-subset-for-vertnet/issues/1). VertNet has adopted GitHub to manage annotations of collection data, which is nice, but it only works if there's someone at the other end ready to engage with people like me who are making annotations. I suspect this is mostly not going to be the case, so why would I bother annotating the data? Yes, I know that VertNet has only just set this up, but that's missing the point. Supporting this model requires customer support, and who has the resources for that? If I don't get the sense that someone is going to deal with my annotation, why bother?
So, the issues here are that the owner gets all the rights, the annotators have none, and in practice the owners might not be in a position to make use of the annotations anyway.
OK, if the owner/annotator model doesn't seem attractive, what about wikis? Let's put the data on a wiki and let folks edit it, that'll work, right? There's a lot to be said in favour of wikis, but there's a disadvantage to the basic wiki model. On a wiki, there is one page for an item, and everyone gets to edit that same page. The hope is that a consensus will emerge, but if it doesn't then you get edit wars (e.g., When taxonomists wage war in Wikipedia). If you've made an edit, or put your data on a wiki, anyone can overwrite it. Sure, you can roll back to an earlier version, but so can anyone else.
Wikis bring tools for community editing, but overturn ownership completely, so the data owner, or indeed any individual annotator has no control over what happens to their contributions. Why would an expert contribute if someone else can undo all their hard work?
So, if sticky notes and wikis aren't the solution, what is? I've been looking at Fluidinfo lately. There's an interview here, and a book here. The company has gone quiet lately (apparently focussing on enterprise customers), but what matters here is the underlying idea, namely "social data".
Fluidinfo's model is that it is a database of objects (representing things or concepts), and anyone can add data to those objects (they are "openly writable"). The key is that every tag is linked to the user, and by default you can only add, edit, or delete your own tags. This means that if a data provider adds, say a bibliographic reference to the database, I can edit it by adding tags, but I can't edit the data provider's tags. To make this a bit more concrete, suppose we have a record for the article with the DOI 10.1163/187631293X00262. We can represent the metadata from CrossRef like this:
"crossref/doi" : "10.1163/187631293X00262",
"crossref/title" : "A taxonomic review of the pondskater...",
"crossref/journal" : "Insect Systematics & Evolution",
"crossref/issn" : [ "1399-560X", "1876-312X"]
Note the use of the namespace "crossref" in the tags. This is data that, notionally, CrossRef "owns" and can edit, and nobody else. Now, as I've discussed earlier (Orwellian metadata: making journals disappear) some publishers have an annoying habit of retrospectively renaming journals. This article was published in Entomologica Scandinavica, which has since been renamed Insect Systematics & Evolution, and CrossRef gives the latter as the journal name for this article. But most citations to the article will use the old journal name. Under the social data model, I can add this information (in bold):
"crossref/doi" : "10.1163/187631293X00262",
"crossref/title" : "A taxonomic review of the pondskater...",
"crossref/journal" : "Insect Systematics & Evolution",
"crossref/issn" : ["1399-560X", "1876-312X"],
"rdmpage/journal" : "Entomologica Scandinavica","rdmpage/issn" : ["0013-8711" ]
My tags have the namespace "rdmpage", so they are "mine". I haven't overwritten the "crossref" tags. Somebody else could add their own tags, and of course, CrossRef could update their tags if they wish. We can all edit this object, we don't need permission to do so, and we can rest assured that our own edits won't be overwritten by somebody else.
This model can be quite liberating. If you are a data provider/owner, you don't have to worry about people trampling over your data, because you (and any users of your data) can simply ignore tags not in your namespace ("ignore those rdmpage' tags, that Rod Page chap is clearly a nutter"). Annotators are freed from their reliance on data providers doing anything with the annotations they created. I don't care whether CrossRef decides to revert the journal name Insect Systematics & Evolution to Entomologica Scandinavica for earlier article (or not), I can just use the "rdmpage/journal" (if it exists) to get what I think is the appropriate journal name. My annotations are immediately usable. Because everyone gets to edit in their own namespace, we don't need to form a consensus, so we don't need the version control feature of wikis to enable roll backs, there are no more edit wars (almost).
A key feature of the Fluidinfo social data model is that the data is stored in a single, globally accessible place. Hence we need a global annotation store. Fluidinfo itself doesn't seem to have a publicly accessible database, I guess in part because managing one is a major undertaking (think Freebase). Despite Nicholas Tollervey's post (FluidDB is not CouchDB (and FluidDB's secret sauce)), I think CouchDB is exactly the way I'd want to implement this (it's here, it works, and it scales). The "secret sauce" is essentially application logic (every key has a namespace corresponding to a given user).
The more I think about this model the more I like it. It could greatly simplify the task of annotating biodiversity data, and avoid what I fear are going to be the twin dead ends of sticky note annotation and wikis.

A field assistant is required to help with research on speciation in Heliconius butterflies. We are studying the genetic basis of traits causing reproductive isolation between a pair of recently diverged sister species ( http://bit.ly/OgJqtx). The field assistant will help to collect data for QTL mapping of the genomic regions involved in the production of colour patterns, pheromones and host plant choice. The field assistant will be required from June - December 2014, but the exact dates are flexible and shorter time periods could be considered. The assistant will work with a postdoctoral researcher in Tarapoto, Peru (a medium sized town at the Amazonian/Andean ecotone). The field assistant’s primary tasks will be to help run experiments on captive populations of butterflies and to collect wild butterflies to supplement captive stocks. The field assistant will develop an excellent practical knowledge of Heliconius butterflies and their host plants (Passifloraceae). S/he will improve his/her understanding of evolutionary ecology and genetics, be actively involved in experimental design, preliminary data analysis, and likely gain co-authorship on a published study. The project will provide excellent preparation for a PhD on tropical biodiversity. The field assistant’s return airfare to Peru and accommodation will be covered, in addition to a small stipend for food and basic living costs. Applicants should hold an undergraduate or Master’s degree in Life Sciences with an interest in Evolutionary Biology, and have a passion for natural history and biodiversity. The successful applicant will need to be independent and comfortable in a culturally challenging environment. Spanish language skills are highly desirable but not essential. Latin Americans are particularly encouraged to apply. Interested candidates should write to Neil Rosser (firstname.lastname@example.org) before 1st May 2014. email@example.com via Gmail

Background: Polytypism in aposematic species is unlikely according to theory, but commonly seen in nature. Ranitomeya imitator is a poison frog species exhibiting polytypic mimicry of three congeneric model species (R. fantastica, R. summersi, and two morphs of R. variabilis) across four allopatric populations (a "mimetic radiation"). In order to investigate chemical defenses in this system, a key prediction of Müllerian mimicry, we analyzed the alkaloids of both models and mimics from four allopatric populations. Results: In this study we demonstrate distinct differences in alkaloid profiles between co-mimetic species within allopatric populations. We further demonstrate that R. imitator has a greater number of distinct alkaloid types than the model species and more total alkaloids in all but one population. Conclusions: Given that R. imitator is the more abundant species in these populations, R. imitator is likely driving the majority of predator-learned avoidance in these complexes. The success of Ranitomeya imitator as a putative advergent mimic may be a direct result of differences in alkaloid sequestration. Furthermore, we propose that automimicry within co-mimetic species is an important avenue of research.
