  Boyacá?s Forgotten Kingdom, Descrição: Colombia is known to be one of the most biodiverse countries in the world. Nevertheless, the current knowledge on inventory and monitoring of biodiversity and ecosystems does not fully reflect this richness, being incomplete in certain regions. Counteracting this situation, the nation-wide ?Colombia Bio? programme has recently been established by the Colombian government with the main aim of making sustainable economic use of Colombia?s biodiversity resources. This programme offers a unique opportunity for Kew and partner organisations in Colombia to undertake primary research on biodiversity and ecosystem services in parts of the country as yet completely unexplored. The goal of this exploratory research is to enable the establishment of a long-term agenda on the conservation and sustainable use of Colombia?s natural capital. Kew Science will be involved in a significant number of research projects over the next 4-5 years (from 2017) under the umbrella of the Colombia Bio programme. The goal of the project described here is to assess the unknown fungal diversity in the department (region) of Boyacá in Colombia, and will run for 10 months until March 2018.. , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Mestrado acadêmico: (1) . , Integrantes: Pepijn Wilhelmus Kooij - Coordenador / NISKANEN, TUULA - Integrante / GAYA, ESTER - Integrante / Suz, Laura M. - Integrante / Davies, Lee - Integrante / Hill, Rowena - Integrante / Aguirre-Hudson, Begoa - Integrante / José Aguilar - Integrante / Henry Arenas-Castro - Integrante / Paul Cannon - Integrante / Elizabeth Downes - Integrante / Daniel García - Integrante / Mailyn González - Integrante / Bibiana Moncada - Integrante / Rocio Pea-Caón - Integrante / Oscar Ruiz Rincón - Integrante / Tatiana Sanjuan - Integrante / Juan Sebastián Silano Uribe - Integrante / Diego Simijaca - Integrante / Natalia Soto Mesa - Integrante / Claudi Vilaregut Soler - Integrante / Andrea Baquero - Integrante / Natalia Vargas Estupian - Integrante / Aída Vasco-Palacios - Integrante., Financiador(es): Newton Fund UK - Auxílio financeiro.

  Symbiont policing and mutualism maintenance, Descrição: Leaf-cutting ants have domesticated fungal crops for ca 10 million years, making them one of the most successful herbivores in the Neotropics. Their fungal symbiont is a reproductively mature mushroom-forming fungus, yet mushrooms are rarely seen. Fungal viruses (mycoviruses) are known to have ?castrating? effects on human cultivated mushrooms, suggesting that ant cultivars could suffer from similar effects. Mutualism is a cooperation between partners that is viewed as a balance in a perpetual battle over resources. Natural selection favours mutualistic interactions that minimise cheating by one partner, including policing mechanisms that stabilise the partnership. Fungus-growing ants of the tribe Attini maintain a stable obligate mutualism with their fungal partner of the mushroom genus Leucoagaricus (Agaricales: Agaricaceae). Each generation, new ant queens bring fungus from the original colony to build their own, causing vertical transmission of the fungus. Fungal reproduction outside this transmission would be a waste of energy for the colony as whole and could introduce new genetic strains; threatening the domesticated phenotype and misaligning the reproductive interests of the ants and their fungal crops. To avoid these destabilising scenarios, the ants actively remove any fruiting body material initiated by the fungus. However, fruiting of the fungal symbiont is rare in general, suggesting the primary cause of fruiting body suppression takes place prior to mushroom formation. Recent pilot studies, using transmission electron microscopy, have shown the presence of a mycovirus in the ant fungal crops. In other (human cultivated) mushroom forming fungi, such as Agaricus bisporus and Pleurotus ostreatus, mycoviruses have been shown to have a ?castrating? effect, causing the fungi to produce malformed fruiting bodies and reduced germination of basidiospores. The mycovirus(es) in this system are potentially functioning to suppress fruit body formation, thereby policing the fungal symbiont and leading to long term maintenance of a stable mutualism. This project aims to identify the mycovirus(es) present in the fungal crops and investigate their role in suppressing mushroom growth.. , Situação: Em andamento; Natureza: Pesquisa. , Integrantes: Pepijn Wilhelmus Kooij - Coordenador., Financiador(es): British Ecological Society - Auxílio financeiro.

  Phylogenetic origin and evolution of asexuality in leaf-cutting ant fungiculture, Descrição: Coevolution is one of the major forces in the origin and maintenance of biodiversity. The fungus-farming ant mutualism is a model coevolutionary system, typified by the leaf-cutting ants (genera Atta and Acromyrmex), which use freshly harvested leaves as substrate for growing a fungal crop on which they depend. The fungus, Leucoagaricus gongylophorus, acts as a versatile and efficient digestive system for the ants by decomposing the harvested plant material,, converting otherwise inaccessible nutrients into specialized energy rich cells (gongylidia) on which the ants feed. Unlike their earlier diverged cousins, the leaf-cutting ants exclusively transmit their fungal symbiont vertically, and no identical free-living fungus has been documented, consistent with the view that the leaf-cutting fungus is a domesticated crop. The leaf-cutting ants originated between 8 and 12 million years ago as the most specialized crown-group of the fungus-growing ants (Attini) and their extant distribution ranges from warm-temperate South America up to the southern regions of the United States. Throughout this range these ants are important (often dominant) herbivores and significant accelerators of nitrogen and phosphorus cycling. However, leaf-cutting ants are often regarded as pests by farmers, because they forage plant material that is readily available in agricultural fields, such as coffee and cacao-plantations, and can cause devastating damage to crops. Theory predicts that reproduction outside of the symbiosis would destabilize the mutualism, as selective forces would act on the partners independently. Consistent with this prediction is the apparent lack of sexual reproduction in L. gongylophorus, based on two lines of evidence: 1) sexually reproductive bodies (mushrooms) have been rarely observed in natural and artificial conditions, and then they have not been proven fertile; 2) no identical or closely-related free-living fungi have been identified, indicating lack of ongoing recombination outside of the symbiosis. Even though sexual reproduction by the fungal symbionts seems to be suppressed throughout the whole tribe of fungus-growing ants, it appears that the growth of mushrooms is more controlled in the leaf-cutting ants. Moreover, selection should favor fungal symbionts with inherent asexuality, for example through loss-of-function mutations leading to lack of mushroom production, increasing colony efficiency by avoiding the growth of costly mushrooms with reproductive interests outside the symbiosis.. , Situação: Em andamento; Natureza: Pesquisa. , Integrantes: Pepijn Wilhelmus Kooij - Coordenador / SHIK, JONATHAN - Integrante / GAYA, ESTER - Integrante., Financiador(es): Royal Botanic Gardens, Kew - Auxílio financeiro.
