It is our pleasure to present this new number of the journal Biodiversidad Neotropical, to the academic and scientific community, a as well as sharing good news related with our editorial advances. The journal recently acquired its own DOI (Digital Object Identifier) 10.18636, allowing to find each item with its own internet address on the web. In addition, the journal has been included in new index platforms: MIAR and Sciary, promoting the international diffusion of scientific results in our contents, and generating a greater impact on the society, the environment and biodiversity.

It is a great honor for us to include in this issue, a work on the characterization of ancestry, crossbreeding and genetic diversity of human population of the Colombian Chocó. This is a collaborative work, conducted by prestigious American (IHRC-Georgia Tech, Applied Bioinformatics Laboratory, School of Biology, Georgia Institute of Technology, and the National Center for Biotechnology Information) and Colombian institutions (PanAmerican Bioinformatics Institute, Biomedical Research Institute of the Universidad Libre, BIOS Centro de Bioinformática y Biología Computacional, Centro de Investigaciones en Biodiversidad y Hábitat of the Universidad Tecnológica del Chocó). Results in this work, demonstrate that human Chocoan populations, have a predominantly African ancestry, with similar contributions from European and Native American ancestors, and suggest a unique genetic heritage for the people of Chocó. Thereupon the Chocó recognition as one of the most bio-diverse places on the planet is now also supported by the significant human genetic diversity.

Nine more contributions complete the content of the present issue, including a floristic characterization of three tropical rain forests of different ages, in the Jardín Botánico del Pacífico at Bahía Solano, Chocó, Colombia. The evaluation of the repellent activity of six total extracts, against adult insects of Tribolium castaneum; an analysis of the trophic ecology Ceratophrys calcarata. The description of the Craugastor stejnegerianus thermal frog litter ecology in Costa Rica. Two inventories of birds, one for the campus of the Universidad de la Amazonia in Caquetá, Colombia, and the other for the nature reserve Laguna Blanca in Paraguay. A study on the performance of a GPS tracking collar on a spectacled bear (Tremarctos ornatus) in the Colombian Andes; and finally, notes about new locations for Caluromys derbianus in Honduras.

We hope for the readers to enjoy this issue.
