Frank's Legacy from a North American Perspective
I am highly honoured to describe the monumental North American legacy of Frank Pantridge. Most emphatically Frank became a great life-changer for many in Europe and the Americas. I thank Alun Evans for this opportunity to focus upon our extraordinary Pantridge endowment. Forty-three years ago one could not stand erect in a North American ambulance. Hearses, limousines and estate wagons transpor...
متن کاملFine-scale niche structure of Neotropical forests reflects a legacy of the Great American Biotic Interchange.
The tendency of species to retain their ancestral niches may link processes that determine community assembly with biogeographic histories that span geological time scales. Biogeographic history is likely to have had a particularly strong impact on Neotropical forests because of the influence of the Great American Biotic Interchange, which followed emergence of a land connection between North a...
متن کاملPopulation structure of the butternut canker fungus, Ophiognomonia clavigignenti-juglandacearum, in North American forests
The occurrence of multiple introduction events, or sudden emergence from a host jump, of forest pathogens may be an important factor in successful establishment in a novel environment or on a new host; however, few studies have focused on the introduction and emergence of fungal pathogens in forest ecosystems. While Ophiognomonia clavigignenti-juglandacearum (Oc-j), the butternut canker fungus,...
متن کاملLegacy of Pre-Disturbance Spatial Pattern Determines Early Structural Diversity following Severe Disturbance in Montane Spruce Forests
BACKGROUND Severe canopy-removing disturbances are native to many temperate forests and radically alter stand structure, but biotic legacies (surviving elements or patterns) can lend continuity to ecosystem function after such events. Poorly understood is the degree to which the structural complexity of an old-growth forest carries over to the next stand. We asked how pre-disturbance spatial pa...
متن کاملNorth American forest disturbance mapped from a decadal Landsat record
Article history: Received 26 December 2006 Received in revised form 8 February 2008 Accepted 9 February 2008 Forest disturbance and recovery are critical ecosystem processes, but the spatial pattern of disturbance has never been mapped across North America. The LEDAPS (Landsat Ecosystem Disturbance Adaptive Processing System) project has assembled a wall-to-wall record of stand-clearing disturb...
