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.

Growth forecasts cut as outbreak hits pharmaceutical, electronics and car supply chains

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.

There are multiple UX solutions for tabs and menus and each of them have their own advantages over another, you just need to pick the best for the case you are trying to solve. At design and development agency Kollegorna we were debating on the most appropriate UX technique for tabs for our client’s website…
