Pollen Can Protect Mahogany From Extinction
2012-04-04 03:28:58

New research from the University of Adelaide could help protect one of the world's most globally threatened tree species - the big leaf mahogany - from extinction. Big leaf mahogany (Swietenia macrophylla) is the most prized mahogany timber around the world. It is at risk of extinction in its native habitats because of the timber trade, particularly in Central and South America.

Compromises between quantity and quality are common in animals, but do the same tradeoffs hold true for plants and their flowers? Most creatures face compromises when they reproduce – the more energy they devote to having lots of babies, the less they can invest in each one. But do the same tradeoffs hold true for plants? Biologists have long assumed that plants with bigger, showier flowers can make fewer of them per plant. But the data don't always hold up, scientists say. A new...

For Stronger Corn, Make It All Female

A Purdue University researcher has taken corn off steroids and found that the results might lead to improvements in that and other crops. Burkhard Schulz, an assistant professor of horticulture and landscape architecture, wanted to understand the relationship between natural brassinosteroids - a natural plant steroid hormone - and plant architecture, specifically plant height. Schulz said corn could benefit by becoming shorter and sturdier, but the mechanisms that control those traits are...

Reproductive assurance in a self-compatible, annual, monocarpic herb, Centaurium erythraea In plants that rely on animals for pollination, the number of seeds they produce, or their relative fitness, is influenced by pollinator visits and the successful deposition of pollen. The number of visits a plant may receive depends partly on pollinator density as well as on conspecific plant density. But what if a plant happens to grow in a population that is small or has very few pollinators...
