We report the optimization of a family of human single chain antibody fragments (scFv) for neutralizing two scorpion venoms. The parental scFv 3F recognizes the main toxins of Centruroides noxius Hoffmann (Cn2) and Centruroides suffusus suffusus (Css2), albeit with low affinity. This scFv was subjected to independent processes of directed evolution to(More)
10 Identifying key food resources for critically endangered species is vital in the design of effective conservation strategies, particularly if these resources are also targeted by anthropogenic activities such as logging. The province of Esmeraldas in NW Ecuador is heavily dependent on commercial logging. It also maintains the only healthy population of(More)
Agricultural systems often involve monocultures that are vulnerable to competitors and pathogens. Successful agriculture, therefore, relies on preventing the contamination of the crop by detrimental organisms or on removing such organisms. The fungus-growing ants exhibit one of the most ancient forms of agriculture, farming a clonal fungal crop that is(More)
There is increasing evidence that large-bodied primates play important roles as seed dispersers and in the maintenance of tree diversity in forest ecosystems. In this study we compared forest regeneration at two sites with differing primate abundances in the Ecuadorian Chocoan rainforest. We predicted: (1) significant differences in primate abundance(More)
Using phage display and directed evolution, our group has progressed in the construction of a second family of human single chain variable fragments (scFv) which bind to scorpion toxins dangerous to mammals. It was observed that scFv C1 only bound initially to toxin Cn2, which constitutes 6.8% of whole venom from the scorpion Centruroides noxius Hoffman.(More)
