Earliest Evidence Of Burials With Flowers Found In Israel Cave
2013-07-03 07:00:37

Lawrence LeBlond for redOrbit.com - Your Universe Online A recent discovery in a cave in Israel has given researchers a new look into how our ancient ancestors treated their dead. Daniel Nadel, an archaeologist at the University of Haifa in Israel, has been leading a team of researchers since 2005 in the excavation efforts at Raqefet Cave on the slopes of Mount Carmel. The discovery was that of a Natufian pair that had been purposely buried together in a grave lined with flowers. The...

Flower Patterns Play Role In Bumblebee Choices
2013-06-20 18:33:49

Lee Rannals for redOrbit.com — Your Universe Online A new study shows bumblebees actually look at flower patterns to help find spots full of nectar. Researchers writing in the journal Naturwissenschaften - The Science of Nature discovered bees prefer radial patterns when looking for food. The team performed a couple of experiments using both radio-frequency identification technology and video recordings. They exposed over 500 flower-naive bees to two types of patterns on...

Alpine Rock Cress Uses Ribonucleic Acid To Tell When It’s The Right Time To Flower
2013-06-10 15:52:15

Max Planck Institute Perennial plants flower only when they have reached a certain age and been subjected to the cold. These two circumstances prevent the plant from starting to flower during winter. George Coupland and his fellow scientists from the Max Planck Institute for Plant Breeding Research in Cologne have now discovered that the Alpine rock cress determines its age based on the quantity of a short ribonucleic acid. Perennial plants carefully balance periods of growth and...

Flowering Agri-environment Schemes Easily Enhance Pollinators
2013-06-10 13:43:51

Pensoft Publishers Agri-environment schemes aimed to promote biodiversity on farmland have positive effects on wild bees, hoverflies and butterflies. Effects on diversity and abundance were strongest when agri-environment schemes prescribed sowing wild-flowers, the more flowering species the better. Organic farms, set-aside land or fields receiving reduced amounts of fertilizer and pesticides generally hosted more wild pollinators than conventionally farmed land. Jeroen Scheper of Alterra...

Self-fertilizing Plants Play Part In Their Own Death
2013-06-10 10:28:56

University of Toronto Many plants are self-fertilizing, meaning they act as both mother and father to their own seeds. This strategy — known as selfing — guarantees reproduction but, over time, leads to reduced diversity and the accumulation of harmful mutations. A new study published in the scientific journal Nature Genetics shows that these negative consequences are apparent across a selfing plant's genome, and can arise more rapidly than previously thought. In the study,...

Genetic And Hormonal Signals Responsible For Shape, Function Of Leaves
2013-05-01 09:48:37

Brett Smith for redOrbit.com - Your Universe Online As the spring flowers (finally) begin to bloom across the United States, take a closer look and you may find a whole host of genetic and hormonal signaling that is responsible for the shape and function of various aspects of the leaves of plants. In the latest edition of the open access journal PLoS Biology, a group of UK biologists has detailed new insights into the differences and similarities between flowering plants´ petal and...

Azaleas are flowering shrubs making up part of the genus Rhododendron. Azaleas were originally classed as a different genus of plant, but now they are recognized as two of the eight sub-genera of rhododendrons - subgenus Pentanthera typified by Rhododendron nudiflorum and subgenus Tsutsusi typified by Rhododendron tsutsusi. There are two types of azaleas: deciduous and evergreen. One of the major differences between azaleas and the rest of the rhododendron family is their size. Another is...

Iris is a genus of flowering plants with showy flowers ranging in color from gold, copper-red or yellow to white, blue, blue-violet, lavender, tan, maroon and purple. Pink and apricot colored irises have also been bred in some species. The name "Iris" can be applied to the genus or to any of the species within it. It is also applied to various subdivisions within the genus. Description There are many species of iris widely distributed throughout the northern temperate zone. Their...
