    A regional analysis of Barí land use intensification and its impact on landscape heterogeneity (1994)
    Springer
    Human ecology 22 (1994), S. 279-316

    ISSN: 1572-9915
    Keywords: cultural ecology ; land use ; landscape ; Barí ; remote sensing ; geographical information system

    Notes: Abstract Since pacification 30 years ago, the Barí of northwest Venezuela have aggregated in villages and have begun to produce cattle and some crops for sale in regional markets. This research analyzes satellite imagery to compare patterns of land use among Barí settlements that differ in their population size, cattle holdings, and distance to nearest marketplace. These comparisons indicate that settlement history mediates the effect of population pressure and herd sizes on land use. Moreover, intensification of land use is associated with greater deforestation and a more heterogeneous landscape, but less biodiversity in woody species.

    Barí spear fishing: Advantages to group formation? (1991)
    Springer
    Human ecology 19 (1991), S. 529-554

    Notes: Abstract A study of spear fishing by the Barí of the Maracaibo Basin provides data demonstrating a benefit accruing to individual fishermen fishing in groups. An analysis of counts of successful and unsuccessful spear thrusts shows that fish are made more vulnerable to spear thrusts by companion fishermen who wear down and confuse the fish. Fish vulnerability is seen to depend on the number of encounters a fish has already survived. This Encounter History effect may be operative in other predator and prey relationships.

    Risk sensitive foraging behavior among the Barí (1991)
    Springer
    Human ecology 19 (1991), S. 509-516 
    Details
    ISSN: 1572-9915
    Keywords: risk-sensitive behavior ; Barí ; protein foraging ; probability payoffs
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Energy, Environment Protection, Nuclear Power Engineering , Ethnic Sciences
    Notes: Abstract Risksensitive behavior can be defined as the active choosing among probability distributions in an attempt to maximize expected utility of returns. An analysis of human foraging behavior is examined in terms of risk sensitivity. Foraging data collected from Barí hunting and fishing trips were tested according to the prediction that future foraging behavior will be dependent on or at least be sensitive to the success of the previous day's trip. An analysis of protein foraging data yields statistically insignificant results, suggesting risk indifference on the part of the Barí.

    Barí exogamy among their territorial groups: Choice and/or necessity (1991)
    Springer
    Human ecology 19 (1991), S. 453-467 
    Details
    ISSN: 1572-9915
    Keywords: demography ; South America ; Barí ; marriage

    Topics: Biology , Energy, Environment Protection, Nuclear Power Engineering , Ethnic Sciences
    Notes: Abstract Considerable demographic data on the Barí were provided by the 1982 Venezuelan Indian census. Some of these data are presented here and used to test the hypothesis, suggested by the Barí themselves, that territorial exogamy was caused largely by a shortage of marriageable women within the territorial group. The hypothesis is disconfirmed, but new insights into the causes of territorial exogamy emerge from the analysis.

    Assumption validity in human optimal foraging: The Barí hunters of Venezuela as a test case (1991)
    Springer
    Human ecology 19 (1991), S. 499-508 
    Details
    ISSN: 1572-9915
    Keywords: optimal foraging ; Barí ; hunting ; Poisson ; Venezuela
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Energy, Environment Protection, Nuclear Power Engineering , Ethnic Sciences
    Notes: Abstract Optimal foraging theory is being used increasingly as a means of understanding human foraging behavior. One of the central assumptions of optimal foraging theory is that prey items or patches are encountered sequentially and as a Poisson process. Using empirical data gathered on the Barí hunters of Venezuela, we assess the validity of this central assumption. We compare our observed distribution of encounter frequencies with an expected Poisson distribution, utilizing chisquare tests and graphic representations. The results are strikingly consonant with the expected Poisson distribution and lend support to the applicability of optimal foraging models to human hunting behavior.
