Technology tracks 'bee talk' to help improve honey bee health
147294 web
(Simon Fraser University) A Simon Fraser University researcher has devised a new bee monitoring system to better understand what more than 20,000 honeybees housed in hives in a local field are 'saying' to each other -- looking for clues about their health. www.eurekalert.org/pub_rele...
Scientists compare soil microbes in no-till, conventional tilling systems of Pacific Northwest farms
148276 web
(American Phytopathological Society) Wheat growers of the inland Pacific Northwest have been slow to adopt no-till farming, in part because short-term residue accumulation can encourage fungal soil-borne disease outbreaks. But over longer periods, researchers at Washington State University and the University of Idaho noticed fewer outbreaks in fields where no-till was practiced for multiple seasons.

Swedish researchers and global fishing companies form coalition for sustainable seas
147468 web
(Stockholm University) A new article in the scientific journal PNAS describes how researchers from Stockholm Resilience Centre at Stockholm University convened the CEOs of several of the world's largest seafood companies to form a new global coalition aiming to end unsustainable practices such as overfishing, modern slavery and destructive impacts on habitats and marine species. www.eurekalert.org/pub_rele...
Financial incentives could conserve tropical forest diversity
147059 web
(University of Missouri-Columbia) The past few decades have seen the rise of global incentive programs offering payments to landowners to help reduce tropical deforestation. In what might be a first of its kind study, University of Missouri researchers have integrated forest imaging with field-level inventories and landowner surveys to assess the impact of conservation payments in Ecuador's Amazon Basin forests. They found that conservation payment programs are making a difference in t... www.eurekalert.org/pub_rele...
Salamanders that breed in the fall are less likely to disperse
147660 web
(University of Missouri-Columbia) With changing environments, pond-breeding salamanders face increasingly hazardous treks as the space between breeding ponds and their non-breeding habitat widens or is degraded. A study from the University of Missouri suggests that a salamander's success may depend more on when it breeds than on the landscape obstacles it might face. Scientists believe that knowing the patterns in which salamanders move back and forth could lead to better forest manage... www.eurekalert.org/pub_rele...
Meadow of dancing brittle stars shows evolution at work
147782 web
(University of Cambridge) Newly described fossil shows how brittle stars evolved in response to pressure from predators, and how an 'evolutionary hangover' managed to escape them. www.eurekalert.org/pub_rele...
Smithsonian manatee count informs policy recommendations
148286 web
(Smithsonian Tropical Research Institute) Smithsonian scientists use sonar to estimate Antillean Manatee populations in the murky waters of Panama's internationally protected San San Pond Sak wetlands. www.eurekalert.org/pub_rele...
Maize from El Gigante Rock Shelter shows early transition to staple crop
147458 web
(Penn State) Mid-summer corn on the cob is everywhere, but where did it all come from and how did it get to be the big, sweet, yellow ears we eat today? Some of the answers come from carbon dating ancient maize and other organic material from the El Gigante rock shelter in Honduras, according to a team of anthropologists who show that 4,300 years ago maize was sufficiently domesticated to serve as a staple crop in the Honduran highlands. www.eurekalert.org/pub_rele...
Biochar shows benefits as manure lagoon cover
147571 web
(American Society of Agronomy) Manure is a reality in raising farm animals. Manure can be a useful fertilizer, returning valued nitrogen, phosphorus, and potassium to the soil for plant growth. But manure has problems. Odor offensiveness, gas emissions, nutrient runoff, and possible water pollution are just a few. New methods may reduce these negatives while potentially adding some positives: biochar covers. www.eurekalert.org/pub_rele...
Plants love microbes -- and so do farmers
147688 web
(University of Queensland) The Australian Sunshine Coast's plant diversity has helped University of Queensland researchers confirm that nurture has the upper hand -- at least when it comes to plant microbes.Australian Centre for Ecogenomics director Professor Phil Hugenholtz said a study of microbial communities necessary for plant development, led by UQ's Yun Kit Yeoh, could improve crop and plant yields. www.eurekalert.org/pub_rele...
