26 Coley, Phyllis D.; Kursar, Thomas A.Using ecological criteria to design plant collection strategies for drug discoveryTropical forests are one of the most diverse and endangered habitats on earth. They have also been portrayed as a source of future pharmaceuticals, yet finding useful compounds can be both scientifically and politically challenging. Increasingly, over the past decade, the potential value of medicina...Drug discovery; Biodiversity2003
27 Goller, FranzWhite-crowned sparrows tutored with syllable pairs can produce full songsDuring their 'sensitive period', young songbirds develop an 'acquired template', representing a memory of the song(s) that it hears. Later, during the sensorimotor phase, birds use this template to evaluate, via auditory feedback, their vocalizations.Acquired template; Sensorimotor period; Temporal isolation2003
28 Sperry, John S.Xylem hydraulics and the soil-plant-atmosphere continuum: opportunities and unresolved issuesReceived for publication July 23, 2002. Soil and xylem are similar hydraulically. An unsaturated conductivity curve for soil is called a vulnerability curve for xylem?but the underlying physical basis is the same. Thus, any transport model that treats unsaturated soil conductivity would benefit by a...Soil?plant?atmosphere continuum; Water potential2003
29 Olivera, Baldomero M.; McIntosh, J. Michaelα-Conotoxins ImI and ImII: similar α7 nicotinic receptor antagonists act at different sitesA novel conotoxin, α-conotoxin ImII (α-CTx ImII), identified from Conus imperialis venom ducts, was chemically synthesized. A previously characterized C. imperialis conotoxin, α-conotoxin ImI (α-CTx ImI), is closely related; 9 of 12 amino acids are identical. Both α-CTx ImII and α-CTx ImI...Conotoxins; Conotoxin ImI; Conotoxin ImII2003
