ARBIMON in IBAC, Brazil 2013

Between September 6 -15, 2013, the ARBIMON team was in Pirenópolis, Brazil participating in the International Bioacoustics Congress. On September 8, Mitch Aide and Marconi Campos-Cerqueira gave a workshop titled, “Automated species identification of birds, frogs, insects, and monkeys from audio recordings using ARBIMON software”.  The workshop was attended by 20 scientists from around the world.  In addition, Mitch presented a talk describing the development and application of the ARBIMON system, and he participated in a roundtable discussion on “Bioacoustics and Animal Diversity.”   Marconi presented a poster highlighting the use of ARBIMON for long-term population monitoring, with examples of species from Costa Rica and Puerto Rico.



ARBIMON in "Día a Día"

August 1, 2013

Jay Fonseca, a Puerto Rican journalist, radio host, lawyer, and political analyst, and currently appears in "Día a Día" and Television news on Telemundo Puerto Rico, interviewed Professor Carlos Corrada Bravo of the Computer Science Department and Mitchell Aide of the Department of Biology from the University of Puerto Rico, Río Piedras Campus. They discussed about the ARBIMON software, and its contributions. Check out the interview in the link below!

ARBIMON Acoustics in Brazil

July 3, 2012


Between June 17 and June 22, 2012, the ARBIMON team was in Bonito, Brazil participating in the annual meeting of the Association for Tropical Biology. On June 17 and 18, we gave a workshop titled, “Automated species identification of birds, frogs, insects, and monkeys from audio recordings using ARBIMON software”. During the meeting, Carlos Corrada gave a talk in a symposium, “New approaches for the biotic inventory of hyperdiverse tropical forests”, and Carlos Milan presented a poster comparing Eleutherodactylus coqui calling activity between wetland and forest habitats in Puerto Rico. In addition, we had a booth where we showed potential users the ARBIMON software package.



A new published article: Real-time monitoring and automated species identification

July 16, 2013

Today, we published an article, Real-time monitoring and automated species identification, in the journal PeerJ. The article describes the hardware and software used to automate audio data collection and species identification. Below are the links to the press coverage of the article. 












ARBIMON’s first species identification workshop

May 1, 2012


On April 28, ARBIMON held its first species identification workshop at the University of Puerto Rico – Rio Piedras. The participants included scientists from US Fish and Wildlife, the Department of Natural Resources, InterAmericana University, and two PhD graduate students. The workshop included an overview of the ARBIMON project, but the majority of the time was spent learning how to use the species identification software. By the end of the workshop all participants had created an algorithm for automating the identification of Eleutherodactylus coqui(common coqui).





US tags tiny PR frog as endangered

October 4, 2012 


By CB Online Staff / The Associated Press

A Puerto Rican frog about the size of a peanut has received federal protection, ending a long battle to list it as an endangered species.

The habitat of the coquí llanero also received protection, covering 615 acres (249 hectares) of freshwater wetland in northern Puerto Rico.Wednesday’s announcement comes two years after the non-profit, Florida-based Center for Biological Diversity sued the U.S. Fish and Wildlife Service so it would respond to a 2007 petition seeking to have the frog classified as an endangered species. The FWS proposed the designation in October 2011.Its new designation now means that it is illegal to kill, harm or capture the frog.The coquí llanero was discovered in 2005, and its eggs have only been found on the bulltongue arrowhead plant. It is one of 17 coquí species.The coquí llanero has a call with such a high-pitched frequency that it can barely be heard. The FWS has said scientists do not have even a rough estimate of how many coquí llaneros exist in the wild.Most of the critical habitat designation, roughly 518 acres, is located in a wetland within the closed Sabana Seca Naval Base and adjacent open military lands in Toa Baja. Managed by the U.S. Department of Defense, this area is identified for residential development. The remaining 97 acres of the wetland designation are managed by the commonwealth of Puerto Rico.The endangered species designation means that the Puerto Rico government and U.S. Department of Defense would have to consult with the U.S. Fish & Wildlife Service before any development is approved.As the demand to revitalize towns and transform impacted lands into productive areas increases, the FWS is seeking to protect and restore the lands that are most important to the coqui llanero’s’ survival while responsibly promoting sustainable development for the benefit of the public.In addition to urban development, the coquí llanero is threatened by many factors, including habitat degradation for flood control projects and competition from invasive wetland plant species. It also is challenged by its highly specialized ecological requirements and limited population distribution, low reproductive capacity, water and soil pollution, use of herbicides, brush fires, and inadequate regulations for its protection.The coquí llanero is one of 17 coquí endemic to Puerto Rico. The common coquí is a cultural symbol of Puerto Rico whose name comes from the male frog’s iconic singing-call “ko-kee.” The coquí llanero’s limited range in the Sabana Seca area is likely the result of historical and current land uses — including urban development, a go-kart track and a landfill. The coquí’s presence in this wetland is significant, indicating a healthy wetland whose benefits include providing habitat for a variety of species, protecting against flooding and recharging groundwater.The coquí llanero’s Latin name (Eleutherodactylus juanariveroi) comes from biologist Juan A. Rivero in recognition of his contributions to Puerto Rican reptiles and amphibians.

XXVII Interuniversity Seminar on Research in the Mathematical Sciences (SIDIM) 2012

March 6, 2012


Last week, Giovany Vega Viera, a MS student in the Department of Computer Sciences and an ARBIMON team member, participated in the XXVII Interuniversity Seminar on Research in the Mathematical Sciences (SIDIM Conference) held at the University of Puerto Rico – Mayaguez. He presented his thesis research in a talk titled, “Improving ROI (Regions of Interest) Pattern Recognition Using Random Markov Fields”. Giovany won the Mathematical Biosciences Institute Conference Award for the best talk among young professors and MS and PhD students. Congratulations Giovany!!!
