Spanish forest ecosystems: Carbon emission will be higher in second half of century

ScienceDaily Botany News - Mon, 03/03/2014 - 08:35
Spanish forest ecosystems will probably emit high quantities of carbon dioxide in the second half of the 21st century. This is the conclusion of a report that reviews the results obtained from the implementation of a forest simulation model that serves as a tool to simulate forest growth processes under several environmental conditions and to optimize Mediterranean forests management strategies in the context of climate change.

MDC offers prescribed fire workshop for landowners in Vichy

News from the MDC - Fri, 02/28/2014 - 17:02
Written By:  Joanie Straub

The March 14 workshop is free, but space is limited and you must preregister by March 12.

VICHY, Mo. - Landowners can learn to use prescribed fire as a land management tool at a prescribed fire workshop presented by the Missouri Department of Conservation (MDC) from 9 a.m. to 3 p.m. on March 14 at the Vichy Volunteer Fire Protection firehouse. The workshop is free, but space is limited and you must preregister by March 12.

Prescribed fire is an ancient technique used to manage grasslands, CRP and old fields for forage production and improvement of wildlife habitat. Used first by Native Americans, the technique is now taught by the MDC across the state.

The nature of color: New formula to calculate hue improves accuracy of color analysis

ScienceDaily Botany News - Fri, 02/28/2014 - 14:01
Color is crucial in ecological studies, playing an important role in studies of flower and fruit development, responses to heat/drought stress, and plant–pollinator communication. But, measuring color variation is difficult, and available formulas sometimes give misleading results. An improved formula to calculate hue (one of three variables characterizing color) has now been developed.

Smoke in the water: Understanding effects of smoke compounds on seed germination

ScienceDaily Botany News - Fri, 02/28/2014 - 14:01
Wildfires, although seemingly destructive, play an important role in plant ecosystems. In ecosystems where it occurs regularly, exposure to fire may initiate seed germination or enhance plant growth. Compounds released as plant tissue burns can break seed dormancy and stimulate germination. In a new article, an efficient system to produce smoke solutions is described to aid investigation of the role of smoke compounds in seed germination and seedling growth.

Beneficial anti-inflammatory effects observed when plant extracts fed to sick pigs

ScienceDaily Botany News - Fri, 02/28/2014 - 12:12
Porcine reproductive and respiratory syndrome is the most expensive and invasive disease for pig producers on a global scale. Though it is not occurring on every farm, it is the biggest disease problem in the pig industry, said an animal sciences researcher.

Unearthing key function of plant hormone

ScienceDaily Botany News - Fri, 02/28/2014 - 10:34
Plants, like animals, employ hormones as messengers, which coordinate growth and regulate how they react to the environment. One of these plant hormones, auxin, regulates nearly all aspects of plant behavior and development, for example phototropism, root growth and fruit growth. Depending on the context, auxin elicits a range of responses such as cell polarization or division. Scientists now report finding the molecular mechanism by which the plant hormone auxin affects the organization of the cell's inner skeletons.

Coral fish biodiversity loss: Humankind could be responsible

ScienceDaily Botany News - Fri, 02/28/2014 - 08:07
Literal biodiversity reservoirs, coral reefs and associated ecosystems are in grave danger from natural and human-made disturbances. The latest World Resources Institute assessment is alarming with 75% of coral reefs reported as endangered worldwide, a figure that may reach 100% by 2050. The numbers are concerning, particularly as coral reefs provide sustenance and economic benefits for many developing countries and fish biodiversity on coral reefs partly determines the biomass available for human consumption.

Controlling zebra chip disease from the inside out

Zebra chip disease in potatoes is currently being managed by controlling the potato psyllid with insecticides. But one specialist is trying to manage the disease symptoms with alternative methods and chemistries.

Manipulating heat, drought tolerance in cowpeas

ScienceDaily Botany News - Thu, 02/27/2014 - 13:46
Cowpeas, known as black-eyed peas in the U.S., are an important and versatile food legume grown in more than 80 countries. Scientists are working to map the genes controlling drought and heat tolerance in recent varieties. Cowpeas were chosen for the study because they are a high protein grain, vegetable, fodder and high nitrogen-fixing legume that can be intercropped with corn, cotton and other crops in many countries. The drought and heat tolerant genes, once defined and cloned, are expected to significantly advance understanding of the molecular basis underlying plant tolerances to these stresses.

Water filter from the sapwood in pine tree branches

ScienceDaily Botany News - Wed, 02/26/2014 - 17:45
If you've run out of drinking water during a lakeside camping trip, there's a simple solution: Break off a branch from the nearest pine tree, peel away the bark, and slowly pour lake water through the stick. The improvised filter should trap any bacteria, producing fresh, uncontaminated water. In fact, scientists have discovered that this low-tech filtration system can produce up to four liters of drinking water a day -- enough to quench the thirst of a typical person. The researchers demonstrate that a small piece of sapwood can filter out more than 99 percent of the bacteria E. coli from water.

Characterization of stink bug saliva proteins opens door to controlling pests

ScienceDaily Botany News - Wed, 02/26/2014 - 14:45
Brown marmorated stink bugs cause millions of dollars in crop losses across the United States because of the damage their saliva does to plant tissues. Researchers have now developed methods to extract the insect saliva and identify the major protein components, which could lead to new pest control approaches. "Other than using synthetic pesticides, there have been few alternative approaches to controlling these pests. By identifying the major protein components of saliva, it now may be possible to target the specific factors in saliva that are essential for their feeding and, therefore, design new approaches for controlling stink bugs," states one of the authors.

Moths trapped with plant-produced sex pheromone

ScienceDaily Botany News - Wed, 02/26/2014 - 12:52
By engineering plants that emitted sex pheromones that mimic those naturally produced by two species of moths, researchers have demonstrated that an effective, environmentally friendly, plant-based method of insect control is possible. While a proof-of-concept experiment, engineering plants to be insect pheromone-producing factories creates an environmentally friendly alternative to pesticides as well as an easier and less expensive method of synthesizing insect pheromones

Ecotoxicity: All clear for silver nanoparticles?

ScienceDaily Botany News - Tue, 02/25/2014 - 13:45
It has long been known that, in the form of free ions, silver particles can be highly toxic to aquatic organisms. Yet to this day, there is a lack of detailed knowledge about the doses required to trigger a response and how the organisms deal with this kind of stress. In the past, silver mostly found its way into the environment in the vicinity of silver mines or via wastewater emanating from the photo industry. More recently, silver nanoparticles have become commonplace in many applications -- as ingredients in cosmetics, food packaging, disinfectants, and functional clothing. To learn more about the cellular processes that occur in the cells, scientists subjected algae to a range of silver concentrations.

Tiger lily heights controlled with flurprimidol preplant bulb soaks

ScienceDaily Botany News - Tue, 02/25/2014 - 11:29
The appropriate concentration of flurprimidol for the 'orange tiger' tiger lily has been evaluated by scientists, who tested for residual effects of flurprimidol the following year. These researchers found that flurprimidol used at optimal concentrations does not affect plant growth or flowering during the second season. The team also found differential responses to flurprimidol for three other tiger lily cultivars, and recommended that growers conduct preplant bulb soak trials to determine optimal concentrations before applying flurprimidol to an entire crop.
