New study: Roundup
Comments (14)Here is another study showing negative effects on frog, brought to you via Prof. joe cummins. ------------------------------------------------------- The current work comes on the heals of French work showing strong effects of the herbicide on animal reproduction after exposure to levels of herbicide on tenth the level recommended for spraying. Glyphosate should be re-evaluated by EPA at this time. However, the response from the regulators will likely be a pr campaign defending the pesticide rather than the frogs. Can the planet live after the frogs are all wiped out? We may be shocked at the impact of the end of frogs may have on the framework of life on the planet. Ecological Applications, 15(2), 2005, pp. 618Â627 THE IMPACT OF INSECTICIDES AND HERBICIDES ON THE BIODIVERSITY AND PRODUCTIVITY OF AQUATIC COMMUNITIES RICK A. RELYEA1 Department of Biological Sciences, 101 Clapp Hall, University of Pittsburgh, Pittsburgh, Pennsylvania 15260 USA Abstract. Pesticides constitute a major anthropogenic addition to natural communities. In aquatic communities, a great majority of pesticide impacts are determined from singlespecies experiments conducted under laboratory conditions. Although this is an essential protocol to rapidly identify the direct impacts of pesticides on organisms, it prevents an assessment of direct and indirect pesticide effects on organisms embedded in their natural ecological contexts. In this study, I examined the impact of four globally common pesticides (two insecticides, carbaryl [Sevin] and malathion; two herbicides, glyphosate [Roundup] and 2,4-D) on the biodiversity of aquatic communities containing algae and 25 species of animals. Species richness was reduced by 15% with Sevin, 30% with malathion, and 22% with Roundup, whereas 2,4-D had no effect. Both insecticides reduced zooplankton diversity by eliminating cladocerans but not copepods (the latter increased in abundance). The insecticides also reduced the diversity and biomass of predatory insects and had an apparent indirect positive effect on several species of tadpoles, but had no effect on snails. The two herbicides had no effects on zooplankton, insect predators, or snails. Moreover, the herbicide 2,4-D had no effect on tadpoles. However, Roundup completely eliminated two species of tadpoles and nearly exterminated a third species, resulting in a 70% decline in the species richness of tadpoles. This study represents one of the most extensive experimental investigations of pesticide effects on aquatic communities and offers a comprehensive perspective on the impacts of pesticides when nontarget organisms are examined under ecologically relevant conditions....See MoreMy new favorite gadget for chopped salads...

Comments (17)Don't throw it away! If you don't want it box it up and send it to Cathy. She collects funny kitchen gadgets. My father taught me to make huge spaetzle noodles. Dumpling he called them. A dozen eggs cracked into a bowl, flour until it is fairly stiff dough, and a half a handful of parsley. Dropped from a spoon into a pot of boiling water. Tip.. wet the spoon in a cup of water bewteen each spoonful of dough so it won't stick... push off into the water with your finger. I've also seen my father roll this dough out on a floured cutting board and cut it into strips for stroganoff noodles. One of my variations that is very delicious is to substitute spinach flour. They take to most any gravy and can be added to soups (don't cook them in the soup). My youngest sister likes them buttered with parmeasan cheese. My father often cooked a chicken, made gravy, and these spaetzle noodles to go with the gravy. After awhile he started leaving the chicken on the stove because everyone ate spaetzle and gravy until they were full. Give them a try Bobby. They are easy to make and difficult to get wrong. They float when cooked and you can even overcook them some without making them bad. They keep in the fridge and reheat perfectly in a microwave. : ) lyra...See MoreQOTD - Do you have a new gadget or quilting aid?
Comments (18)I don't have any new innovative things, but I did have to replace my rotary cutter yesterday. The bolt that went through the blade got damaged somehow (ok, ok, Ill confess...by me pressing too hard and using a cheaper brand of blade)... The new one is so much smoother, but throwing the other one away was like saying goodbye to an old friend. Beu, I have a Fiskars rail riding rotary ruler cutter thingy, but mine is clumsy and I prefer the control of separate cutter and ruler.... I'm glad yours works for you! Glad you've also never cut yourself... of course they do make a rotary cutting glove for protection if you ever want to check it out! I've dropped my cutter on my foot and had my pointer finger resting right on the blade when I went to take a cut one time... I noticed a commercial for the Guidelines 4 quilters ruler that has a sliding guide on it and I think it needs to go on the list... it would be so nice if I could just slide that where I wanted it and not have to manually visually find my line again with each cut. Marsha, I'm glad you like the table.... that will be my next quilting purchase.... I need to write or call and ask them a few questions and it will give me a taste of their customer service before I order the extension table.... Has anyone tried those Superior Titanium top stitch needles yet? They are supposed to last 8 times longer than regular s/m needles and I'm just about ready to pull the trigger on ordering my first package to try... Awesome question (I'm glad we resurrected this idea!)... Can't wait to see what things I didn't even know existed that I can't live without!...See More- 10 years ago
