After 10 years, myth of Crotalaria plantation as a means to prevent dengue fever remains alive


For decades, the controversial method of planting of Crotalaria spp. to attract predatory dragonflies and control insect vectors has been under debate. However, a recent study leaded by BRC researchers elucidate why dragonflies are not attracted by Crotalaria and, thus, cannot not be considered an efficient method for vector control.

Publication of students from BRC's field course highlights the plasticity on aquatic plants


The study investigated one aquatic plant specie (Eichhornia azurea) in Amazon in what regards its capacity of morphological and allometric plasticity in response to plant density. They concluded that such adjustments are important when there is a need for increasing resource uptake. Also, the plasticity observed can help to explain its success across different habitats.

Habitat Integrity Index is shown as a good predictor for organisms in Amazonian streams


Recent publication involving researchers from BRC demonstrates that Habitat Integrity Index (HII) is a good alternative for aquatic biomonitoring in Brazilian streams and other Amazonian countries. The study highlights that the use of HII in field surveys is relatively simple and low-cost, as it does not rely upon specific equipments or technical skills, thus simplifying its implementation in biomonitoring programs. ​

A new species of litter bug (Heteroptera) is found at the BRC study sites!!!


A new species, Voragocoris weirauchae sp.n., is described based on specimens collected in the Brazilian Amazon, representing the first record of the genus from Brazil. ​The study was recently published in the journal Zootaxa. The article contains the description, photographs of habitus, and scanning electron micrographs of the diagnostic features.

Land-use change favors mainly emergent and amphibious species of aquatic plants


The article, published in the scientific journal Ecological Indicators, suggest that different aspects of  macrophyte communities should be considered when creating indexes for environmental integrity. Results are highly relevant for management decisions regarding the preservation of Amazonian freshwater ecosystems.

Study shows the impact of degraded habitats for mammals


In a recent published article (PlosOne), researchers from BRC evaluated the adaptive plasticity of threatened mammal species. Among the four studied species, the peccary presented the least ability to survive in more altered environments. The authors reinforce the importance of forest remnants for the survival of endangered mammal species in regions of high anthropogenic pressure, as in the eastern Brazilian Amazon. The full article can be accessed by clicking in the figure (left).

Course in Biological Interactions


The Biological Interactions project, in partnership with the PPGBE (MPEG), offered the course from 16-20 November. Twenty-five participants attended the course, including many postgraduate students from different institutions. The course comprehended analyzes of biological interactions and how they can be applied to contexts related ecology, conservation and restoration of ecosystems. It also focused on setting up networks and calculating metrics. The BRC congratulates the organizers and all involved.

BRC on newspaper!


Brazilian newspaper publish a report highlighting the importance of the research consortium on forest recovery of the Hydro mining activities in Paragominas. The report emphasize the different techniques to bring back the vegetation to the areas where bauxite was extracted in order to recompose the biodiversity, as well the program for monitoring the mammals in the region.

Field Course part II - Norway


The second part of the Field Course in tropical rainforest ecology and biodiversity just ended. What a pity! Students loved the experience of being in Norway. This part of the course comprises two weeks, where students from Brazil and Norway join again, now in Oslo. Activities included DNA extraction and analysis, scientific writing, city tour, and hiking in the mountains. Fortunately, they even managed to see snow!

Jaguar project


Yeah! The jaguar team was in the field this month and successfully managed to capture a jaguar for tagging with GPS collars. The transmitters from the collar will give GPS positions for the instrumented animal every 1.5 hours, for more than a year. The purpose is to monitor the movement, habitat use, and living area of the largest feline in the Americas. Congratulations for everyone involved in this great achievement!!

BRC is awarded in a Conference in Russia


On September 2019, in Krasnoyarsk (Russia), Hydro's biologist Victor Barbosa presented a report containing the researches developed by BRC. The work, based on the compilation of the BRC's results, received a prize in the section "International Bauxite, Aluminum and Aluminum Study Committee (ICSOBA)". Congrats Victor!

BRC signing cerimony


Congratulations BRC! Thanks to all our efforts, the cooperation is now extended to 2023. There was a fantastic signing ceremony in Belém on Tuesday. Thanks everybody that participated and we are looking forward for new challenges!

Norwegian ambassador at BRC seminar


The new Norwegian ambassador to Brazil, Nils Martin Gunneng, speaking at the BRC seminar "Amazon biodiversity and Evolution" at MPEG 31 October. The auditorium was full, the presentations interesting, and the potential for expanded cooperation great.

Two international BRC seminars coming soon


Belém will host two international seminars on October 31st. In the morning, the topic will be biodiversity and in the afternoon, the discussion is about geoscience. Join us! Free registration for both seminars!

BRC master students


BRC has two master thesis in the pipeline. Juliana Santos is surveying about habitat use for herbivorous mammals in a mosaic of degraded land in the eastern Amazon. Ana Ribeiro investigates the distribution and habitat use for the order Carnivora (Mammalia) in a mosaic of degraded land in the eastern Amazon.

Here are some pictures of the master students during fieldwork for maintenance and collection of camera trap photos.

Jaguar project


We are already testing the equipment for the jaguar project. This is an extension of the camera traps. Some jaguars will be tagged with telemetry collars. The data will contribute for the environmental management and conservation of the wildlife.

The Biodiversity Research Consortium Brazil-Norway (BRC) was established in 2013. Uniting five Brazilian and Norwegian institutions, the main aim of the cooperation is to develop environmental research in the eastern Brazilian Amazon.
