Chorus song of the indri (Indri indri: Primates, Lemuridae): Group differences and analysis of within-group vocal interactions Baker-Medard, Merrill S. A.; Baker, Myron C.; Logue, David M. The loud chorus songs of the group-living lemur Indri indri are a striking feature of rainforest areas of eastern Madagascar. Despite some research on the conspicuous vocal display of the indri, two hypotheses have not been addressed: do groups differ in the acoustic properties of their songs, and is there evidence of coordinated singing between individuals within groups. We recorded and analyzed the songs of three indri groups to examine these two questions. To answer the first question, we made quantitative spectral measures on songs of the three groups and performed multivariate analyses of the acoustic features of the notes constituting the songs. Our results showed songs of the three groups differed significantly, although there was overlap between groups. To answer the second question, we classified note types and quantified their occurrence as overlapping and abutting pairs. We found non-random associations between sequential note types in all three indri groups. These associations were consistent among groups, suggesting that individuals follow consistent answering rules when contributing to choruses. Whether indris use acoustic group identifiers in management of behavioral strategies and how within-group coordinated note production might function remain unknown. We compare our results to a number of taxonomically diverse species that live in groups and broadcast chorus and duet vocal signals. Open access article.

A locally funded Puerto Rican parrot (Amazona vittata) genome sequencing project increases avian data and advances young researcher education Oleksyk, Taras K.; Pombert, Jean-Francois; Siu, Daniel; Mazo-Vargas, Anyimilehidi; Ramos, Brian; Guiblet, Wilfried; Afanador, Yashira; Ruiz-Rodriguez, Christina T.; Nickerson, Michael L.; Logue, David M.; Dean, Michael; Figueroa, Luis; Valentin, Ricardo; Martinez-Cruzado, Juan-Carlos Background: Amazona vittata is a critically endangered Puerto Rican endemic bird, the only surviving native parrot species in the United States territory, and the first parrot in the large Neotropical genus Amazona, to be studied on a genomic scale. Findings: In a unique community-based funded project, DNA from an A. vittata female was sequenced using a HiSeq Illumina platform, resulting in a total of ~42.5 billion nucleotide bases. This provided approximately 26.89x average coverage depth at the completion of this funding phase. Filtering followed by assembly resulted in 259,423 contigs (N50=6,983 bp, longest=75,003 bp), which was further scaffolded into 148,255 fragments (N50=19,470, longest=206,462 bp). This provided ~76% coverage of the genome based on an estimated size of 1.58 Gb. The assembled scaffolds allowed basic genomic annotation and comparative analyses with other available avian whole-genome sequences. Conclusions: The current data represents the first genomic information from and work carried out with a unique source of funding. This analysis further provides a means for directed training of young researchers in genetic and bioinformatics analyses and will facilitate progress towards a full assembly and annotation of the Puerto Rican parrot genome. It also adds extensive genomic data to a new branch of the avian tree, making it useful for comparative analyses with other avian species. Ultimately, the knowledge acquired from these data will contribute to an improved understanding of the overall population health of this species and aid in ongoing and future conservation efforts.

News flash! Both Mastering SVG and The HTML and CSS Workshop are available as eBooks for $5 starting today.

Like many of you I’m working from home for a while. As a mental health strategy, I’m going to do some writing and coding in the hour or so I get back each day from not having to commute. The first post, which will follow today, will be my thoughts on working from home. I […]

While we’re preparing an upcoming release, I didn’t want the day to go by without mentioning that ten years ago today, HTML5 Boilerplate was released. Here’s the story of the project as we wrote it up a few years ago. The History of HTML5 Boilerplate Sometime in 2009… “Wouldn’t it be great if we created […]

And so it happened that I published the latest post of mine on Codrops, not here this time. It’s about styling <input type="file" /> by taking the advantage of <label>. The technique is not perfect – nothing is perfect that imitates native HTML elements – but having in mind its pros & cons, I found it to be the most appropriate solution for styling file inputs.

It’s common to present dates on the Web in a format such as "Published on September 12th, 2015", or "09/12/2015 09:41:23".

Each of these examples tells the full date and/or time of some kind of activity – be it a published article, or a reader comment, or perhaps an uploaded video.

Date formats like this might seem perfectly reasonable. After all, they’re informative and human-readable. Well yes, but “human-readable” doesn’t necessary mean users will readily be able to understand how recently the activity has occurred. The Web is a fast-moving place, and giving your content a sense of freshness could be the key to engaging with your audience.

I combined my ideas and practical solutions into an article which you are very welcome to read on SitePoint.

You've been hard at work optimizing your site. You've already done things like lazy-loading Google Maps and been wondering if there was anything else you could do. For example, is there anything we can do to improve the loading of ads? Good news, there is some things you can do. You can respect user's mobile data plan by loading ads only when they are likely to appear in the viewport zone. You can also serve ads in the right size in accordance to the screen of the device. That would be nice of you. That would not only be responsive but also responsible.

I've written an article on that and got it published on CSS-Tricks.

Lately, I've been obsessed with optimizing performance through lazy-loading. Recently, I've written on how to lazy-load Google Maps and on how to lazy-load responsive Google Adsense. Now it's time for Disqus, a service for embedding comments on your website. It's a great service. It eliminates the headache of developing your own local commenting system, dealing with spam, etc. Recently, I've been working on implementing the widget in one of my projects.
