“…Bone survival is known to be variable in New Zealand's coastal dunes (Worthy 2004), yet many aspects of the taphonomy of such bone deposits remain to be studied. Wind patterns, sand mineral composition, sand pH and hydrological conditions are all factors that are likely to play major roles in influencing the preservation, and hence maximum age, of bone deposits in coastal dunes, yet these relationships are poorly understood.…”

“…obs). One explanation for this is that a certain proportion of shell grit in the sand might buffer the pH, providing better preservation conditions for bones (Worthy 2004). Knowledge about the conditions under which bones are accumulated and preserved in coastal dunes will assist with identifying and protecting the sites most likely to contain such important palaeofaunal records, and with interpreting the presence/absence of faunal species at different locations and times in the past (Worthy 2004;Holdaway et al 2004).…”

Spatial distribution of late Holocene bird bones in the Mason Bay dune system, Stewart Island, New Zealand

Many of New Zealand's coastal sand dune systems contain naturally accumulated deposits of late Holocene bones, providing an important archive of our pre-settlement faunas. However, the accumulation and taphonomic processes that operate in natural dune deposits are poorly understood. Here, I contribute to our understanding of these processes through analysing spatial patterns of bone distribution in an extensive late Holocene dune system at Mason Bay, Stewart Island. The bone assemblage was collected between December 2002 and February 2003, and included 2880 identified bones from at least 28 bird species. These included extinct species (South Island piopio, Turnagra capensis), regionally rare species (e.g. weka, Gallirallus australis and New Zealand falcon, Falco novaeseelandiae) and locally rare species (e.g. South Island kākā, Nestor meridionalis meridionalis). Significant effects of distance to beach, and distance to the edge of woody vegetation, were found for bones of certain bird groups. The results indicate three main sources of bird bones for the Mason Bay dune system assemblage: 1. nesting colonies within the dunes; 2. storm-wrecked seabirds; and 3. birds inhabiting woody vegetation bordering the dunes. Understanding source biases for dune bone deposits will allow more informed interpretations about the composition of the local prehistoric faunal communities.

“…Nature subsequently published two letters criticizing Quist and Chapela's methods and interpretations (Kaplinsky et al 2002, Metz andFütterer 2002), and a response providing new data (Quist and Chapela 2002), along with an unprecedented editorial statement that data in the original paper did not justify publication (Nature 2002). Following this, Nature published two letters critiquing the critiques and Nature's editorial stance (Suarez 2002, Worthy et al 2002, claiming criticism of Quist and Chapela was related to a $25 000 000 grant to UC Berkeley from the agricultural biotechnology company Syngenta that Chapela had opposed.…”

ABSTRACT. Proponents of genetically engineered (GE) crops often assume that the risk management used in the industrial world is appropriate for small-scale, traditionally based agriculture in the Third World. Opponents of GE crops often assume that risk management is inappropriate for the Third World, because it is inherently biased in favor of the industrial world. We examine both of these assumptions, by rethinking risk management for GE crops and transgenes, using the example of maize transgene flow from the U.S. to Mexico. Risk management for the Third World is a necessary first step of a broader benefit-cost analysis of GE crops, which would include comparisons with existing varieties and with alternative varieties such as transgenic farmer varieties and organic varieties. Our goal is to use existing information on GE crops and on the social and biological characteristics of Third World agriculture to identify key processes that need to be considered in risk management, and the additional research required to adequately understand them. The four main steps in risk management are hazard identification, risk analysis (exposure x harm), risk evaluation, and risk treatment. We use informal event trees to identify possible exposure to GE crops and transgenes, and resulting biological and social harm; give examples of farmers' ability to evaluate social harm; and discuss the possibilities for risk treatment. We conclude that risk management is relevant for Third World agriculture, but needs to be based on the unique biological and social characteristics of small-scale, traditionally based agriculture, including the knowledge and values of Third World farmers and consumers.
