When it comes to pollen formation, seed plants go for overproduction Plants producing flower pollen must not leave anything to chance. The model plant thale cress (Arabidopsis), for instance, uses three signaling pathways in concert with partially overlapping functions. The yield becomes the greatest when all three processes are active; however, two are sufficient to form an acceptable quantity of flower pollen. In a new study, Peter Huijser and his colleagues at the Max Planck Institute for...

Global warming is already affecting the earth in a variety of ways that demand our attention. Now, research carried out at the Hebrew University of Jerusalem indicates that many tree species might become extinct due to climate change if no action is taken in time. According to the research, trees which disperse their seeds by wind, such as pines and maples, will be unable to spread at a pace that can cope with expected climate changes. The research, which focused on the ecological...

FISHERS, Ind., Jan. 18, 2011 /PRNewswire/ -- Research shows that more than 50 percent of New Year's Resolutions, most of which have to do with diet or nutrition, don't last beyond January. Two leading nutritionists aim to reverse that trend by encouraging people to focus on one realistic and attainable resolution: eat more fruit. According to Stephanie Clarke and Willow Jarosh, licensed nutritionists, registered dietitians, and co-founders of C&J Nutrition, fruit is an essential part...

Plant biologists are facing pressure to quantify the response of plants to changing environments and to breed plants that can respond to such changes. One method of monitoring the response of plants to different environments is by studying their vein network patterns. These networks impact whole plant photosynthesis and the mechanical properties of leaves, and vary between species that have evolved or have been bred under different environmental conditions. To help address the challenge of...

SAN ANTONIO, Jan. 13, 2011 /PRNewswire/ -- While the rest of the nation battles frigid cold and snow storms, South Texans are dealing with a massive blizzard of pollen. Record-breaking Mountain Cedar pollen counts - the worst since the 90s - are causing even the least symptomatic to suffer. Mountain Cedar, the most prolific pollinating tree in the world, is a drought-tolerant evergreen shrub or small tree, most prevalent in South Central Texas. The pollen can cause a severe allergic...

Results help predict tree failures, estimate damage from diseased trees Landscape trees, valued for their aesthetic nature and their environmental benefits, are becomingly increasingly valuable in urban environments. A single mature tree can add considerable value to commercial and residential properties. Conversely, tree mortality can result in significant economic losses. Urban trees must endure adverse growing conditions that reduce their structural strength and subject them to stresses,...

From southern Africa's pineapple lily to Western Australia's swamp bottlebrush, flowering plants are everywhere.  Also called angiosperms, they make up 90 percent of all land-based, plant life. New research published this week in the Proceedings of the National Academy of Sciences provides new insights into their genetic origin, an evolutionary innovation that quickly gave rise to many diverse flowering plants more than 130 million years ago. Moreover, a flower with genetic programming...

Cyclamen persicum is a flowering, herbaceous plant from the Myrsinaceae family. It is commonly referred to as the Persian cyclamen. C. persicum is a tuberous plant. A tuber is a modified plant structure that is enlarged to store nutrients. The flowers and leaves come from buds at the top of the tuber. Roots emerge from the sides and bottom. Wild specimens have heart-shaped leaves that grow as long as 6 inches. They are usually green in color, with a light green marbling effect on the...

Kelp Forest

Kelp forests are areas that are underwater with a high density of kelp. They’re recognized as one of the most dynamic and productive ecosystems on Earth. Smaller regions of anchored kelp are known as kelp beds. Kelp forests can be found worldwide throughout polar and temperate coastal oceans. In the year 2007, kelp forests were discovered in tropical waters near Ecuador as well. While they are physically formed by brown macroalgae of the order Laminariales, kelp forests offer a unique...

humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
