Duetting as a collective behavior Logue, David M.; Krupp, Daniel B. Mated birds of many species vocalize together, producing duets. Duetting behavior occurs at two levels of organization: the individual level and the pair level. Individuals initiate vocalizations, answer their mates’ vocalizations, and control the structure and timing of their own vocalizations. Pairs produce duets that vary with respect to duration, temporal coordination, and phrase-type combinations, among other properties. To make sense of this hierarchical structure, organize duetting research, and identify new avenues of investigation, we advocate a “collective behavior” approach to the study of duets. We critically review key terminology in the duetting literature in light of this approach, and elucidate six insights that emerge from the collective behavior approach: (1) Individual-level behaviors describe pair-level behaviors, but the opposite is not true; (2) The level of organization informs how we test for the rules that govern behavior; (3) Functional hypotheses about duetting must distinguish individual from group characters; (4) Stimulus-response, cybernetics, and entrainment offer alternative hypotheses for the cognitive control of duetting behavior; (5) Avian duetting has the potential to be a model system for the ontogeny of vocal interaction; and (6) The collective behavior approach suggests new avenues of research. Ultimately, we argue that nearly every aspect of duetting research stands to benefit from adopting a collective behavior approach. This approach also has applications to other forms of interactive vocal communication in birds and primates, including humans. Sherpa Romeo green journal. 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.

The Centre has questioned the legality of SEZs in absence of any provision for the same in the Master Plan Delhi (MPD) 2021.

A recent Intelligence Bureau (IB) report has claimed that some well-known NGOs are working to stall economic development at the behest of their foreign donors. Activists and rights groups have been up in arms ever since the report was leaked.

The refugee question in the Indian subcontinent dates back to 1947 when India was partitioned. A horrifying feature of the birth of free India – and Pakistan – was the large mass of refugees who were forced to relocate in the most adverse conditions and amidst brutal violence.

In the next 3-4 weeks researchers would be able to get at least 200-300 isolates and this information would help them to make some further conclusion about the behaviour of this virus.
