This paper explores the attempts to co-ordinate rural resistance and struggles in South Africa during apartheid through a case study of the Association for Rural Advancement (AFRA), a land NGO established in Natal in 1979. It was a small group but had a significant local and national impact. The paper addresses three key questions concerning the character and works of AFRA: (1) What was the character and strategy of AFRA in the politicised context of the late 1970s and 1980s? (2) Was there any historical continuity and discontinuity with early attempts by Natal liberals and African landowners to organise anti-removal campaigns in the 1950s? (3) How and to what extent could AFRA negotiate the increasing influence of the Inkatha and KwaZulu government over Natal rural communities? The paper aims to serve as a critical evaluation of AFRA's strategies and activities, and its relationship with rural communities up to 1990 when land movements became nationwide.

Each year, millions of monarch butterflies from eastern North America migrate to overwinter in 10–13 discrete colonies located in the Oyamel forests of central Mexico. For decades efforts to track monarch migration have relied on observations and tag-recapture methods, culminating with the discovery of the wintering colonies in 1975. Monarch tag returns from Mexico, however, are few and primarily from two accessible colonies, and therefore tag-recapture techniques have not quantified natal origins or distinctiveness among monarch populations at wintering sites. Such information would be invaluable in the conservation of the monarch and its migration phenomenon since the wintering sites currently are threatened by habitat alteration. Here we show that stable hydrogen (δD) and carbon (δ13C) isotope ratios of wintering monarchs can be used to evaluate natal origins on the summer breeding range. Stable-hydrogen and carbon isotopic values of 597 wintering monarchs from 13 wintering roost sites were compared with isotopic patterns measured in individuals at natal sites across their breeding range over a single migration cycle. We determined that all monarch wintering colonies were composed of individuals originating mainly from the Midwest, United States, thereby providing evidence for a panmictic model of wintering colony composition. However, two colonies showed more northerly origins, suggesting possible priority colonies for conservation efforts.
