Fossil and genetic history of a pinyon pine (Pinus edulis) isolate
The most isolated northern stand of Colorado pinyon pine (Pinus edulis) at Owl Canyon, Colorado, USA has a broad and flat size class distribution common to population expansions, with the largest and oldest trees near the center of the grove. Analyses of fossil packrat (Neotoma sp.) middens within the grove indicate that the stand originated by long—distance dispersal rather than by vicariance, a

Physical aspects of Hurricane Hugo in Puerto Rico
On 18 September 1989 the western part ofHurricane Hugo crossed eastern Puerto Rico and the Luquillo Experimental Forest (LEF). Storm-facing slopes on the northeastern part of the island that were within 15 km of the eye and received greater than 200 mm of rain were most affected by the storm. In the LEF and nearby area, recurrence intervals associated with Hurricane Hugo were 50 yr for wind veloci
