Fire-catalyzed vegetation shifts in ponderosa pine and Douglas-fir forests of the western United States
Increased wildfire activity combined with warm and dry post-fire conditions may undermine the mechanisms maintaining forest resilience to wildfires, potentially causing ecosystem transitions, or fire-catalyzed vegetation shifts. Stand-replacing fire is especially likely to catalyze vegetation shifts expected from climate change, by killing mature trees that are less sensitive to climate than juveniles. To understand the vulnerability of forests t…
Disturbance in Biogeography
Ecological disturbances, both natural and anthropogenic, are inherent components of all ecosystems that fundamentally affect their structure and function. At landscape and regional scales, differences in the types and spatiotemporal attributes of disturbances profoundly influence coarse‐scale biogeographic patterns and the evolution of the component biota. Modern research on disturbances such as wildfires and tree‐killing insects in ecology and b…
The Physical Geography of South America
The Physical Geography of South America, the eighth volume in the Oxford Regional Environments series, presents an enduring statement on the physical and biogeographic conditions of this remarkable continent and their relationships to human activity. It fills a void in recent environmental literature by assembling a team of specialists from within and beyond South America in order to provide an integrated, cross-disciplinary body of knowledge abo…

Are Wildfire Mitigation and Restoration of Historic Forest Structure Compatible? A Spatial Modeling Assessment
In response to catastrophic wildfires, wide-reaching forest management policies have been enacted in recent years, most notably the Healthy Forests Restoration Act of 2003. A key premise underlying these policies is that fire suppression has resulted in denser forests than were present historically in some western forest types. Therefore, although reducing the threat of wildfire is the primary goal, forest managers commonly view fuel treatments a…

The Ecology and Biogeography of Nothofagus Forests
Focusing on the tree species Nothofagus, or southern beech, ecologists and biogeographers here provide a comprehensive examination of the distribution, history, and ecology of this species that predominates in forests from highland New Guinea at the equator to the subantarctic latitudes of Tierra del Fuego. The Nothofagus genus offers a fascinating key to understanding historical plant geography and modern vegetation patterns
Tree-ring based reconstructions of northern Patagonia precipitation since AD 1600
Long-term reconstructions (400 years) of seasonal and annual precipitation variations were developed for northern Patagonia east of the Andes using a new set of 16 tree ring-width chronologies from Austrocedrus chilensis (D.Don) Endl. Reconstructions, which capture between 41 and 50% of the precipitation variance, show that the twentieth century contains the most extreme long periods of wetness and dryness in the past 400 years. Since about ad 19…

Steppe Expansion in Patagonia?
Westward expansion of the Patagonian steppe and retrocession of Andean forests due to increasing aridity over the past one or two millennia has been a persistent theme in the ecological and paleoecological literature for at least half a century. New evidence from pollen profiles, tree-ring analysis, vegetation structure, and photographic and documentary historical sources does not show the expansion of the steppe. Instead, over the past century t…
Recent Vegetation Changes along the Forest/Steppe Ecotone of Northern Patagonia
In northern Patagonia over a west-to-east distance of approximately 50 km, the vegetation changes from Nothofagus rainforests through woodlands of Austrocedrus chilensis to steppe dominated by bunchgrasses and shrubs. Analysis of tree population age structures and photographic comparisons of the forest/steppe margin over the past century indicate an expansion of trees into the steppe. Throughout northern Patagonia, Austrocedrus chilensis and othe…

The Effects of Introduced Wild Animals on New Zealand Forests
Although New Zealand lacks native terrestrial mammals (except for two species of bats), more than 50 species of mammals have been introduced by human beings and have become established since the late eighteenth century. The impact of introduced browsing and grazing mammals on the vegetation of New Zealand is widely perceived as an ecological disaster involving severe depletion of the plant cover and widespread accelerated erosion. Although there …
Forest Preservation in the Western Highlands of Guatemala
HE rapid rate of human destruction of tropical forests and its ecological as well as social consequences is a theme of growing concern among both social and natural scientists. The implications of this massive landscape transformation in tropical America have been widely discussed with regard to the loss, or impending loss, of valuable forest genetic resources, accelerated soil erosion, and the destruction of wildlife habitats.' Geographers have …
Native Population Decline in Totonicapán, Guatemala∗
The Spanish conquest of the New World resulted in a rapid and drastic reduction of the native population. This demographic collapse was caused by the battles of conquest, the severe disruption of native economies, and the devastating impact of Old World diseases on an immunologically virgin population. In the case of Totonicapán in the western highlands of Guatemala, population decline was initiated by lethal epidemics introduced via Mexico which…
