Entropika, Defenzoor del Año 2015

"Defenzoor del Año" (Animal Defender of the Year) is a tribute created 11 years ago by Defenzoores with the support of the University of Antioquia, Colombia, which recognizes the outstanding work of individuals and entities in the promotion of respectful coexistence with animals.

"Last Wednesday, 30th September, in the Auditorium of the University of Antioquia, the Defenzoor del Año Award was given to Fundación Entropika, an entity of the Colombian Amazon that has been working for the animals and communities of that region.

The public law suit filed in 2011 by the foundation and its Director against the indiscriminate and massive use of the only nocturnal monkeys of the new world, gave rise to a sentence of the State Council that reinforced the status of animals as sentient beings and the State's duty to protect the rights of nature and all of its species; which the Sentence C 666 of the Constitutional Court already had declared in 2010.

The Scientific Director of the foundation, Angela Maldonado, who enjoys a growing admiration of environmentalists and animalists from around the country, travelled from Leticia to receive the Award."

New IPS (International Primatological Society) policy on trade in primates captured in the wild

Entropika is leading the working group "On the use of primates and their trade", created during the last International Congress of Primatology in Hanoi, Vietnam. This group proposed a policy to IPS (being the most important international community in the field of Primatology) that seeks to regulate the use of primates in research, zoos and parks, amongst others.

The proposal provides recommendations on the trade of primates to prevent the use of wild animals, asserting the exclusive use of animals bred in captivity, due to the high trafficking of primates that are declared as bred in captivity, but that really are being trafficked from tropical countries to breeding centres. Moreover, cooperation with international authorities such as INTERPOL and CITES is emphasized.

The working group consists of Angela M. Maldonado, Mary Blair, Claire Beastall, Drew Cronin, Nicholas Malone, Sian Waters, Daniel Stiles, and Janette Wallis. The new policy has been approved by IPS shareholders with 205 votes in favour and 3 against.

Cleaning day in La Esperanza neighbourhood, Leticia

Together with the help of the Municipal Administration of Leticia, the Environmental Police, the Army, Fundación FATA, Fundación Amazonas Sin Límites, the local school of Pacho Vela and Corpoamazonía, Entropika organized a cleaning day in La Esperanza, marginal neighbourhood in Leticia. People living in the neighbourhood were invited by the students of Pacho Vela to bring their recyclable (plastic, cardboards, paper, etc.) and non-recyclable waste (organics and others) to two recollection points. The recyclable waste was then transported by the Environmental Police to the recycling plant of Fundación Amazonas Sin Límites, and the non-recyclable was transported by the Municipal Administration to the city’s sanitary landfill. Fundación FATA and the Army were in charge of cleaning the main park and roads of the neighbourhood. The president of the Communal Action Board and Corpoamazonía socialized the new timetable of waste recollection in Leticia; responsibility which will be taken over by the Municipal Administration of Leticia on the 28th of August 2015.

Entropika's primate census database published on the GBIF website

Entropika’s dataset of visual detections of primates was developed to provide long-term and reliable census records of the occurrence of primates at the Colombian – Peruvian Amazonian border. This study provided baseline information on the primate community at 11 sampling sites exposed to different levels of hunting (low, medium and high hunting pressure) and under different protection categories (protected area, indigenous land, private reserve, state reserve and forest without any protection). These data provide crucial information for the implementation of conservations strategies. The dataset is composed out of 1,623 visual detections of 11 primate species (5 families, 10 genera) collected between March 2005 and May 2015 over 761 days of effective diurnal and nocturnal census fieldwork. It is currently the most complete census dataset of primates in the Colombian – Peruvian Amazonian border, making it an invaluable resource for research in the area.

The dataset is freely available in English and its metadata in Spanish from the Global Biodiversity Information Facility website.

Freeze-dried yellow chilli in the shops of the Wingham Wildlife Park

In an attempt to reduce pressure on natural resources Entropika and the Wingham Wildlife Park, Kent, UK, are looking for sustainable economic alternatives that might help to replace the income obtained by local people from the trade of wildlife. In November 2013, Entropika won a public benefit law suit (popular action) using night monkeys as flagship species that were live caught for the malaria research market. Currently, trapping permits were revoked by the highest Colombian Court. Although this represents a milestone ruling that improves ecosystems conservation in the Colombian Amazon, many indigenous families that were trapping the monkeys have lost this income. Entropika, with the support of the Wingham Wildlife Park, are looking for ways to commercialise the freeze-dried yellow chilli pepper, a high quality and completely organic product. If together we can guarantee the long term commercialization of the yellow-chilli, we will involve the families of ex-collectors of night monkeys in this project and guarantee an alternative income for them.

The chilli can be bought online from the Wingham Wildlife Park's website here.

Interview of Angela Maldonado for Nocturna RCN

Who is Angela Maldonado? The conservationist who holds the research of Manuel Elkin Patarroyo in check:

"RCN Nocturna interviewed Angela Maldonado, founder of Fundación Entropika, who defends primates of the Colombian Amazon from being used as guinea pigs in biomedical research. The primatologist announced that on May 26, 2014, authorities will verify the implementation of the sentence of the State Council concerning the case of the scientist Manuel Elkin Patarroyo, who was questioned for capturing monkeys."

29th November 2013

State Council's final sentence protects owl monkeys and their habitats revoking hunting permits

The second instance ruling of the State Council (Consejo de Estado) of Colombia, revoked the hunting permits of owl monkeys (Aotus vociferans) for malaria research that were granted to the Foundation Institute of Immunology of Colombia (FIDIC). The sentence adheres to the first instance ruling issued by the Administrative Court of Cundinamarca (Popular Action No. 25000232400020110022701, filed by the primatologist Dr. Angela Maldonado and the solicitor Gabriel Vanegas).

Magistrate Enrique Gil Botero protected the collective rights regarding administrative morality as well as the sustainable use of natural resources in border areas, focusing in the conservation of owl monkeys. In addition, he ordered environmental authorities to regulate repopulation fees, as established by law.

"The courtroom emphasized that the decision is not an attempt to undermine scientific research in the country, but that, for the use and exploitation of animals by humans, it is necessary to comply with legal requirements and to ensure they are not subject to cruel and degrading treatments".

The sentence of the State Council, which orders the creation of a verification committee in order to guarantee compliance to the judgment, sets out a new challenge for Entropika's team as member of this committee: ensure the implementation and fulfillment of the sentence. For example, if a new permit is granted, the FIDIC is obliged to implement a captive breeding program of the species it wants to use.

We believe the decision to be a historic achievement for the conservation of Colombian wildlife and their ecosystems. It also makes it clear that we can still put our hopes in the Colombian judicial system, and we wholeheartedly welcome the decision of the State Council. Fundación Entropika once again would like to convey its gratitude for the continuous and unconditional support of the following institutions and individuals, who joined our cause for the last five years:

  • Funding institutions: The Whitley Fund for Nature, The Rufford Small Grants, Rainforest Concern, WWF - EFN, The International Primate Protection League (IPPL – US), The British Union for the Abolition of Vivisection (BUAV - UK), The Kilverstone Charitable Trust, and The American Society of Primatologists.
  • Campaign and institutional support: Tikuna communities in Colombia and Peru.

Visit from The DuMond Conservancy

We had the visit of Dr Sian Evans, director of the DuMond Conservancy (US), and Dr. Robert Cooper, one of the first scientists conducting primate census in Colombia during the early 70s. Both of them are experts in the Aotus (night monkeys). We gave them an update of the current advances of the popular action to stop the illegal trade in night monkeys for biomedical research. Although currently trapping permits are revoked, however the regional environmental authority and the biomedical facility continue releasing monkeys after experimentation into indigenous territories. A supporting letter for the popular action was submitted by Dr Evans and Dr. Cooper to the court. In addition, we established collaboration between volunteers from the DuMond Conservancy and the participatory video group “Omagua” from Mocagua indigenous community. This project will start in April-May, 2013.

New investigation from the BUAV on the trade in night monkeys in Peru and Colombia

The British Union for the Abolition of Vivisection is a leading animal protection organisation based in the UK. Sarah Kite, BUAV Director of Special Projects stated:

"Our investigation reveals not only the cruel nature in which these owl monkeys have been torn from their homes and families, but also the destruction that hunting causes to forests that are home to a host of species. We urge the Colombian and Peruvian CITES authorities and governments to put an end to this cruel trade and to focus efforts on preserving their rich and diverse native wildlife."

XXIV Congress of the International Primatological Society (IPS), Cancun, Mexico

New information on the ecology (Argentina), conservation (Colombia) and non-invasive use of owl monkeys (Aotus spp.) in laboratories (U.S.) was presented during the IPS symposium titled "The Biology of Owl Monkeys: A Poorly Understood and Unique Anthropoid". Several primatologists backed the request of A. Maldonado of obtaining the IPS’s institutional support for the popular action that aims at eradicating the illegal trafficking of this genus used for malaria research in Colombia. As a result, we obtained a letter of institutional support from the IPS which was approved during the assembly.

5th July 2012

Sentence of Popular action in favour of the conservation of night monkeys in Colombia

On 5th July 2012, Judge Claudia Elizabeth Lozzi Moreno from the Administrative Court of Cundinamarca provided a first instance ruling against the Institute of Immunology Foundation of Colombia - FIDIC, the Ministry of Environment and Sustainable Development of Colombia, and the Corporation for the Sustainable Development of the Southern Amazon - CORPOAMAZONÍA. The Popular action instituted by Angela Maldonado and the environmental solicitor Gabriel Vanegas, protects the collective rights and interests of Colombian society which are infringed by the permits granted to the FIDIC, legally represented by Dr. Manuel Elkin Patarroyo, for the studying and scientific hunting of the Aotus vociferans (Amazonian night monkey), used in the research of a "synthetic vaccine for malaria caused by Plasmodium falciparum" in the Colombian department of Amazonas.

The verdict recognizes the defending entities as culpable of not complying with their duty to ensure the protection of biodiversity and the integrity of the environment, and of not complying with Colombia's international commitments to the Convention on International Trade in Endangered Species of Wild Fauna and Flora – CITES; simultaneously incurring in a number of environmental, administrative and, in general, anti-juridical, irregularities and anomalies.

This Popular action was instituted in April 2011 and accepted by the court in June 2011. The hard evidence provided was compiled by more than 50 appendices composed of:

  1. Legal documents regarding the permits granted to the FIDIC since 1999, acquired through right of information requests to the environmental authorities.
  2. Scientific publications from the FIDIC that presented the use of Aotus nancymaae and Aotus nigriceps in their research (including translations into Spanish done by sworn English-Spanish translators).
  3. Interviews and trapping methods carried out by Peruvian collectors of night monkeys recorded in 2010, while we collected Aotus nancymaae from Peru, under the research permit (Resolution) N° 428-2009-AG-OGFFS-OGEFFS, granted by the Peruvian Ministry of Environment. This work was done in collaboration with Peruvian biologists from the San Marcos University (Lima, Peru).
  4. Several technical concepts granted by Colombian universities.
  5. Scientific publications confirming the population status of Aotus spp. in the Colombian-Peruvian border (2010-2011).
  6. Denounces made by Peruvian community authorities regarding the continuous trade in night monkeys.


The court's decision is the first step to stop the illegal trade in night monkeys, as current permits were revoked. From the 4 institutions that were sued, only the FIDIC and the Ministry of Environment appealed. The law case against the FIDIC will thus be transferred to another court. This achievement, that sets a step forward in strengthening the environmental law and the conservation of natural resources in Colombia, could not have been possible without the support of several institutions and individuals. We therefore would like to deeply thank:

  • Funding institutions: The Whitley Fund for Nature, The Rufford Small Grants, WWF - EFN programme (Andrea Santy), The International Primate Protection League (IPPL – US): Dr. Shirley McGreal and team, and The British Union for the Abolition of Vivisection (BUAV - UK).
  • Campaigning and institutional support: Tikuna communities in Colombia and Peru. The Colombian Primatological Society, San Marcos University and CITES, Peru (Fanny Cornejo and Dr. Victor Pacheco). The DuMond Conservancy (Dr. Sian Evans), ProWidlife, The Contraloria del Amazonas (Dr. Jairo Osorio - 2011).
  • Logistics, technical concepts, publications revisions and other relevant documents: National University of Colombia (Bogota): Claudia Brieva, Prof. Thomas Defler and Marta Bueno. Universidad Javeriana: Dr. Manuel Ruiz. Andes University: Dr. Pablo Stevenson. Oxford Brookes University: Prof. Simon Bearder. Amacayacu National Park: Eliana Martínez and Alex Alfonso.
  • Individuals: Lina Pelaez, Xyomara Carretero, Dr. Bernardo Ortiz, Dr. Eduardo Fernández-Duque, Dr. José Arturo Gutiérrez, Martin Stanley, Jaime Maldonado, Thomas Lafon, and Entropika’s volunteer team.
  • Research permits: Colombian Park system and Ministry of Agriculture of Peru.

Sounding the Amazon basin with the IDEAM

Together with Jennifer Fowler from the University of Montana, USA, Jaime Tamayo and Fredy Jiménez from the IDEAM (Colombian meteorological services) of Leticia, Entropika tested a radiosonde system developed by GRAW. The advantage of using GRAW is that it is cheaper than the system currently used by the IDEAM, while keeping similar standards of quality. This year, no soundings were launched in Leticia, as radiosonde prices have increased. It should be noted that this issue is recurrent in developing countries of Africa and South America.

The GRAW radiosonde system was found to work perfectly well, reaching altitudes of 30 kilometres without difficulties, for as much as half the price of the radiosondes currently used by the IDEAM. This system proves to be a viable alternative to conduct cheaper daily soundings in Leticia.

The week of soundings was concluded with a presentation and demonstration of a sounding flight to the orphanage "La Aljaba". Pictures of this educational outreach can be found here.

The floods in the tri-border area leave numerous victims behind

The level of the Amazon river over March to May 2012 was higher than ever recorded before in the tri-border area, engendering devastating floods and forced population migration. The Amacayacu National Park and houses in the communities located along the rivers have had to be evacuated.

Around 230 families from the indigenous communities of Mocagua, San Martin, Palmeras (Colombia), Vista Alegre and Yahuma (Peru) lost their cultivations. In places located on lower grounds, such as the community of Palmeras, houses have had to be evacuated. In Vista Alegre, and other communities on the Peruvian side of the Amazon River, floods and subsequent damages were more severe and, in some cases, entire communities were wiped off the map. However, support of the Peruvian authorities has been almost non-existent.

The indigenous communities of the Amazon river are currently going through a difficult period. The major impact on human livelihoods is the scarcity of food caused by the destruction of local crops. Other consequences of the floods see the discontinuation of a vast majority of economic and academic activities. At this point any help is welcome. Donations can be sent to Entropika in order to buy tools and seeds to re-locate local crops.

Testing AnaSonde-3M sounding equipment in the Colombian Amazon

Jennifer Fowler, physics instructional laboratory coordinator from the University of Montana, USA, and Abby Thane, her student, came to Leticia to test sounding equipment developed by AnaSphere and train Entropika's staff in the collection of meteorological data (temperature, relative humidity, atmospheric pressure). This project is to be integrated into Entropika’s work in climatology, aiming to raise awareness on climate change through local training and the setting up of weather stations in private reserves and other study sites.
