Cross-Pollinations: The Marriage of Science and Poetry (Credo)
A pioneering ethnobotanist, Gary Paul Nabhan credits the arts with sparking unlikely scientific breakthroughs and believes that such "cross-pollination" engenders new forms of expression that are essential to discovery. In this highly readable book, he tells four stories to illustrate this idea. In the first, coping with color blindness in art class leads to his career as a scientist; in the second, ancient American Indian songs, when translated, reveal an understanding of plants and animals that rivals modern research; in the third, a poem inspires an approach to diabetes using desert plants; and in the fourth, a coalition of scientists and artists creates the Ironwood Forest National Monument in the Sonoran Desert. .

Effects of pollination distance on reproduction and offspring [An article from: Biological Conservation]
This digital document is a journal article from Biological Conservation, published by Elsevier in 2006. The article is delivered in HTML format and is available in your Amazon.com Media Library immediately after purchase. You can view it with any web browser. Description: Fragmentation of habitats has resulted in increased inbreeding for many plant species, while the introduction of foreign seed material for ecological restoration has resulted in crosses between plants from distant populations. Both processes may reduce plant fitness and increase the risk of extinction. Variation in the expression of inbreeding and outbreeding depression has been found among different genotypes and among populations, but little is known about large scale geographical patterns within species. We studied the effects of cross-proximity on seed production and offspring performance in the perennial meadow plant Hypochoeris radicata (Asteraceae) from five populations in each of three European regions (Bohemia in northwest Czechia, Northern Hesse in central Germany, and Salland in the central Netherlands). Five artificial cross types were conducted with varying proximity of mates: selfing (self), within family crosses (WF), within population crosses (WP), between population crosses (BP), and between region crosses (BR), and the offspring were grown in a common garden. Independent of the region of origin of the maternal plant, selfing, WF and BP crosses resulted in lower seed set and germination than WP crosses, indicating partial self-incompatibility, inbreeding depression and reduced performance in the F1 progeny resulting from outbreeding. However, crosses between regions resulted in similar seed set and germination as within population crosses. For late traits, the effects of inbreeding and interpopulation crosses differed among regions. WP crosses exhibited the highest survival, flowering and multiplicative fitness only in progeny from Czech maternal plants. Our results suggest that the sensitivity of populations to introgression may vary among regions and that outbreeding depression does not necessarily increase with interpopulation distance. However, the current study investigated only effects in the F1 in a common garden and outbreeding depression may be stronger in the F2 and in field populations. .
