rbgeColombia, eight years of ongoing collaborative research

Last week, we had the opportunity to present the results of more than eight years of ongoing collaborative research between Colombia and the UK during the Colombia State visit. The event, hosted by the Natural History Museum in London, brought together leading institutions in biodiversity research with a particular focus on Colombia.

Some photos of the event below.

Neotropical dry forests make it to the cover of Science!

science-cover

We are very excited to announce that a new paper on the plant diversity and conservation of neotropical dry forests has been published in the journal Science. This paper is the result of a massive collaborative effort from DryFlor – the Latin American and Caribbean Seasonally Dry Tropical Forest Floristic Network – and highlights the challenges facing the conservation of this highly threatened biodiversity hotspot.

The Wild Magic of Colombian biodiversity

We were delighted to attend the screening of the documentary Colombia Magia Salvaje on Thursday 28th June at the Royal Botanic Garden Edinburgh (RBGE). Along with one hundred and fifty enthusiastic attendants, we embarked on a journey through Colombia’s incredibly diverse ecosystems. The magnificent shots took us from immaculate snow capped peaks in the Andes to the endless Amazon rainforest. The film also features some of the country’s most representative animals and plants. Animals such as the jaguar – the largest feline in the Americas – and the spectacled bear – the only bear species native to South America – made an appearance. So did the wax palm, Colombia’s national tree which can be found from 2000 meters above sea level, growing up to 45 m on the steep Andean slopes! Just to give you a taster.

Colombia Magia Salvaje is the first of its kind for Colombia and it is the most watched documentary in the history of the country’s cinema. It has successfully introduced global audiences to the extraordinary biodiversity of Colombia, the second most biodiverse country in the World, and raised awareness about the unfortunate but very real threats facing its ecosystems – expansion of agricultural and industrial activities, illegal logging, illegal trade of wildlife, water pollution, extensive mining exploitation and habitat degradation.

The event was jointly organised by RBGE and the Embassy of Colombia in the United Kingdom. A selection of photos from the reception preceding the screening is shown below. All photos by Amy Fokinther.

Congratulations Eugenio

Congratulations to Eugenio Valderrama who successfully defended his PhD thesis at RBGE one week ago (apologies for the late posting!). Eugenio´s PhD utilized DNA sequence data obtained from a screen of markers from transcriptomes of three species of Renealmia (Zingiberaceae). The markers were used to produce a dated phylogeny of nearly all the species that was then used to compare diversification rates between African and Neotropical lineages of the genus. Faster rates were found in the Neotropical lineages, consistent with the hypothesis of more rapid speciation in the Neotropics being responsible for the greater diversity found there. This rapid speciation may be associated with the uplift of the Andes mountains in Northwestern South America from the mid to late Miocene. Eugenio also produced an account fo the Colombian species of Renealmia.

The Age of Chocolate

Together with researchers at the University of the Andes, University of Miami and the USDA we have recently published an article that investigates the diversification history of Theobroma (the genus to which Theobroma cacao, the source of chocolate, belongs). We show that the genus and its relative Herrania diversified from approximately thirteen million years ago. This diversification coincided with, and may in part have been caused by, the formation of the Andes Mountains in Northwestern South America. Colombia is home to 50% of the 20 or so species in Theobroma and is thus a centre of diversity for the genus.

We also show that Theobroma cacao evolved 10 million years ago which means that we should not be surprised to see extensive genetic diversity within the species. Varieties of cacao that have different flavours or may be resistant to fungal diseases may be of benefit to a growing chocolate industry. Maintenance of this genetic diversity in its natural state, together with the animals that pollinate flowers and disperse fruits in native ecosystems, has the potential to assist with improving the quality and quantity of production that could help ensure an environmentally and economically sustainable future for the chocolate industry.
