• Community based biodiversity monitoring in Mexico: current status, challenges, and future strategies for collaboration with scientists

      Pritchard, Diana J. (Springer, 2013-07-18)
      An array of social and political actors, from international to local levels, increasingly demand monitoring data on biodiversity and ecosystem functions. As elsewhere, prevalent approaches in Mexico emphasize the collection of scientific data regarding biological indicators, by professionals, for conservation planning, global targets, and biological inquiry. These are complicated, expensive, and dependent on external funding. They also fail to engage with communities, many of whom practice traditional forms of monitoring to manage their local environments and livelihoods. Community-based monitoring, an approach involving collaborations between scientists and communities, has the potential to contribute to sustainable forms of resource use management and as a cost-effective method. Efforts could develop once local rights of use and traditional knowledge systems are recognized, access to information is ensured, and a broad array of relevant environmental and social indicators are included.
    • Sediment impacts on growth rates of Acropora and Porites corals from fringing reefs of Sulawesi, Indonesia

      Crabbe, M. James C.; Smith, David J. (Springer, 2005)
      Small changes in environmental parameters can cause significant changes in growth rates. Often, environmental parameters influencing growth can be multifactorial, so that high energy and high sedimentation together can reduce growth (Cruz-Pinon et al. 2003), while changes in temperature, salinity, and sedimentation can influence not only growth but also diversity and abundance of corals(Lirman et al. 2003). Using digital videophotography and computer image analysis, as well as physical measurements, we have surveyed the reefs near the island of Hoga, where a Marine Research Station run by Operation Wallacea is situated. Our studies were to test the hypothesis that sedimentation and insolation on Porites lutea and Acropora valeniennesi corals from fringing reefs of Sulawesi in Indonesia influenced coral growth. Radial and linear growth rates were measured.
    • Use of Coniothyrium minitans as a biocontrol agent and some molecular aspects of sclerotial mycoparasitism

      Whipps, J.M.; Sreenivasaprasad, Surapareddy; Muthumeenakshi, S.; Rogers, C.W.; Challen, M.P. (Springer, 2008-07)
      he use of the sclerotial mycoparasite Coniothyrium minitans as a biological control agent of diseases caused by sclerotium-forming pathogens especially Sclerotinia sclerotiorum is briefly reviewed. A number of studies have examined production and application methods, integrated control, ecology, and modes of action in order to understand the biology of the mycoparasite and enhance activity and reproducibility of use. Recently, development of a number of molecular-based techniques has begun to allow the examination of genes involved in mycoparasitism. Some of these procedures have been applied to identify pathogenicity genes involved in the infection of sclerotia of S. sclerotiorum by C. minitans and this work is discussed.
