• Anthropogenic and topographic correlates of natural vegetation cover within agricultural landscape mosaics in Turkey

      Pekin, Burak K. (2016)
      ...I assessed the influence of anthropogenic and topographic variables on the extent of agricultural mosaics with high natural vegetation cover in the country of Turkey where a large extent of natural and semi-natural vegetation is maintained by traditional agriculture. GIS layers depicting human land use, elevation, slope, roads and population data were obtained and summarized at two spatial scales, within provinces and for 100km2 grid cells covering the country’s entire agricultural land area.…
    • Effect of widespread agricultural chemical use on butterfly diversity across Turkish provinces

      Pekin, Burak K. (2013)
      …I assessed the effects of a major component of agricultural intensification, agricultural chemical use, and land-cover and climatic variables on butterfly diversity across 81 provinces in Turkey, where agriculture is practiced extensively but with varying degrees of intensity…. Although overall butterfly richness was primarily explained by climatic and land-cover variables, such as the area of natural vegetation cover, threatened butterfly richness and the relative number of threatened butterfly species decreased substantially as the proportion of agricultural households using pesticides increased. These findings suggest that widespread use of agricultural chemicals, or other components of agricultural intensification that may be collinear with pesticide use, pose an imminent threat to the biodiversity of Turkey.…
    • The i5K Initiative: Advancing arthropod genomics for knowledge, human health, agriculture, and the environment

      Evans, Jay D.; Brown, Susan J.; Hackett, Kevin J.; Robinson, Gene; Richards, Stephen; Lawson, Daniel; Elsik, Christine; Coddington, Jonathan; Edwards, Owain; Emrich, Scott; et al. (2013)
      Insects and their arthropod relatives including mites, spiders, and crustaceans play major roles in the world’s terrestrial, aquatic, and marine ecosystems. Arthropods compete with humans for food and transmit devastating diseases. They also comprise the most diverse and successful branch of metazoan evolution, with millions of extant species. Here, we describe an international effort to guide arthropod genomic efforts, from species prioritization to methodology and informatics. The 5000 arthropod genomes initiative (i5K) community met formally in 2012 to discuss a roadmap for sequencing and analyzing 5000 high-priority arthropods and is continuing this effort via pilot projects, the development of standard operating procedures, and training of students and career scientists. With university, governmental, and industry support, the i5K Consortium aspires to deliver sequences and analytical tools for each of the arthropod branches and each of the species having beneficial and negative effects on humankind.
