    Natural history of crop-related wild species: Uses in pest habitat management (1983)
    Springer
    Environmental management 7 (1983), S. 85-89 
    Details
    ISSN: 1432-1009
    Keywords: Natural history interpretation ; Stability and diversity ; Resistance mechanisms ; Biological control ; Community structure
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract The natural histories of crop-related wild species in their native habitats can be used to develop novel pest management strategies. Traditionally, such information has provided insights for biological control, plant breeding, crop management, and applied ecology Further insights can be garnered.

    Grass carp status in the United States: A review (1983)
    Springer
    Environmental management 7 (1983), S. 151-160 
    Details
    ISSN: 1432-1009
    Keywords: Grass carp ; Biological control ; Nuisance aquatic weeds ; Fisheries ; Aquaculture ; Reproductive requirements ; Arkansas management plan ; Sterile hybrids
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract Grass carp (Ctenopharyngodon idella Val.) were introduced into the United States in 1963 as potential biological control agents for nuisance aquatic weeds. Since that time an oftentimes bitter controversy has raged over its effects on sportfishing, and its possible natural reproduction and naturalization in North America. This review considers the history, ecology, and present status of grass carp in the United States in light of the voluminous scientific research conducted since its importation. Particular attention is given to the role of grass carp in the fisheries management plans of Arkansas. Recent development of a sterile, triploid grass carp hybrid may lead to widespread use of grass carp to control nuisance aquatic weeds in culturally eutrophicated waters of the United States.

    Women as hunters among the matses of the Peruvian Amazon (1983)
    Springer
    Human ecology 11 (1983), S. 339-343 
    Details
    ISSN: 1572-9915
    Keywords: Matses ; women ; hunting ; Amazon ; Peru
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Energy, Environment Protection, Nuclear Power Engineering , Ethnic Sciences
    Notes: Abstract Matses women of the Peruvian Amazon rain forest hunt with men, and couples bring back more meat than men alone. This results from the association of women with capture of collared peccary, a large catch. Typical Amazonian beliefs about women persist, but some new features (like day care) are pertinent to Matses hunting adaptation.

    Tropical forest mimicry in Swiddens: A reassessment of Geertz's Model with Amazonian data (1983)
    Springer
    Human ecology 11 (1983), S. 35-45 
    Details
    ISSN: 1572-9915
    Keywords: Shifting cultivation ; tropical forest ecology ; Amazon
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Energy, Environment Protection, Nuclear Power Engineering , Ethnic Sciences
    Notes: Abstract Geertz's famous hypothesis that horticulturalists practicing shifting cultivation intercrop their plots to mimic the protective structure of the tropical forest is evaluated in view of data on the structural ecology of the tropical forest and swidden plots in Amazonian Ecuador. The cultivation practices of the Siona-Secoya Indians reveal a three-fold typology of cropping patterns (high-diversity intercropping, low-diversity intercropping, and monocropping), with variation among the types in terms of plot size and distribution, cultigen inventory, structural complexity, and function. These gardens and the tropical forest are compared and analyzed in terms of morphology, ecological characteristics, and human manipulation and utilization. Gardens with high-diversity intercropping show certain similarities to the tropical forest, as Geertz's model predicts, but their highly transient structure does not function as a mature ecosystem. Furthermore, plots with low-diversity intercropping and monocropping show few similarities to the forest. Garden structure is best understood in terms of the economic utilization of tropical cultigens displaying specific habits, rather than by analogy to tropical forest physiognomy and function.

    Roads, speculators, and colonization in the Ecuadorian Amazon (1983)
    Springer
    Human ecology 11 (1983), S. 385-403 
    Details
    ISSN: 1572-9915
    Keywords: Amazon ; colonization ; roads ; policy
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Energy, Environment Protection, Nuclear Power Engineering , Ethnic Sciences
    Notes: Abstract In view of the generally disappointing performance of colonization projects in the Amazon basin, unusual projects merit close scrutiny because they may suggest a more effective organizational form for the colonization of humid lowlands. With this end in mind, this article examines those aspects of the Upano-Palora project in southeastern Ecuador that are attributable to the project's unusual plan of establishing settlements first and building the roads afterwards. It concludes that the “settlements first, roads second” developmental sequence reduced the costs of the project, produced an egalitarian pattern of landownership, and contributed to a pattern of land use that had potentially damaging ecological effects. These findings suggest that variations in the timing of road building have an important impact on outcomes in new land settlement schemes.
