flower : : the specialized part of an angiospermous plant that occurs singly or in clusters, possesses whorls of often colorful petals or sepals, and bears the reproductive structures (such as stamens or pistils) involved in the development of seeds and fruit : blossom — Webster
Flower, sometimes known as a bloom or blossom, is the reproductive structure found in plants that are floral (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to effect reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) or allow selfing (fusion of sperm and egg from the same flower). Some flowers produce diaspores without fertilization (parthenocarpy). Flowers contain sporangia and are the site where gametophytes develop. Many flowers have evolved to be attractive to animals, so as to cause them to be vectors for the transfer of pollen. After fertilization, the ovary of the flower develops into fruit containing seeds. In addition to facilitating the reproduction of flowering plants, flowers have long been admired and used by humans to beautify their environment, and also as objects of romance, ritual, religion, medicine and as a source of food. — Wikipedia

New approach to stem soil erosion
on March 19, 2019 at 1:43 pm
Topsoil and nutrient runoff are two serious challenges of sustainable agriculture. Perennial crops can help solve these problems by preserving cropland productivity without requiring substantial dietary and manufacture shifts. Although the development of perennial corn has long been an idea, a major roadblock has been the lack of knowledge about the genetics of perennialism. SDSU researchers Drs. Yang Yen and Donald Auger have been working on this problem. […]

Species often experience a genetic bottleneck that diminishes genetic variation after speciation or introduction into a new area. Though bottlenecks in population size always reduce fitness and evolutionary potential, introduced species often become invasive. This is known as the genetic paradox of invasion. […]

A new study published in Ecology Letters is using observations made by Henry David Thoreau—19th-century American naturalist, social reformer, and philosopher—to explore the effects of climate change on tree leaf-out and, as a result, the emergence of spring wildflowers. […]
