I wrote a text about the development and evolution of the turtle shell on The Node: Turtles in a nutshell.
It shows the beginning of shell formation in embryos and how this can help us understand the evolution of such unique body pattern. 3D animations and fossils are included!
Never thought I would post a vertebrate on this website… but having shoulders inside the rib cage made me make an exception, poor things :p
I was already playing with Mendeley API and took the opportunity to put an idea into practice: aggregate bibliographic references related to a taxon. It is not a particularly new idea, and it also does not differ much from searching a taxon name on google or scopus, but since Mendeley database is based on its users’ collections, it is possible to extract some interesting information. For example, find out which articles are more popular ou create trending topics with popular taxa based on the number of readers and related publications.
Regardless of the source, article data also allows to extract useful information such as the most active authors on a certain taxon, network of collaborators, annual variation in the number of related articles, popular research topics for each group, etc. Integrating the data and using visualization tools it would be possible to “see” holes in the knowledge or follow the history of one’s research.
Imagine if every article was freely available with contained information (metadata) about the studied organisms with taxonomic classification, occurrence data, collection sites, dna sequences, citations with semantic markup, research topics, hypotheses to test, methods, raw data, etc. Anyone would be able to have a summary of the current knowledge about an organism. Specially interesting to set research quidelines and avoid spending money with the same mistakes; optimization of science. And do not forget about the possibility to attach observations, annotations, discussions, unsolved questions, and other collaborative activities.
Well, after creating a prototype of the idea, I have just pust the basic functions of the aggregator to work. Nothing I wrote above is included, just a search interface where you can use a scientific or common name and a page for each taxon with a list of related references and some sorting options. If a taxon is not in the database, it searches in realtimes, therefore, it is necessary to wait a little and reload the page (at least until I automate this).
If you are interested you can test the Living Bibliography at livingbib.organelas.com. Just remember it is completely experimental, I do not garantee that your favorite articles will appear or that the information will be accurate (there are many duplicated articles, wrong author names, badly formatted titles, swapped journal names, and so on at Mendeley). I don’t know how much I’ll be able to work on it, but the source code is open and I would love to hear ideas and suggestions :)
Metamorphosis is a dramatic life-changing event for many invertebrates. It’s the intersection between two distinct lives – larval and adult. It is how a caterpillar becomes a butterfly.
The process is fascinating, specially when you have the chance to see it happening with your own eyes. You too can see it in the video A Sea Biscuit’s Life.
Because intersection is essentially another word for metamorphosis, I submitted a photomicrograph of a metamorphosing sea biscuit from my master’s thesis research. It made it to the final and was a runner-up!
