I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Adirondack boreal peatlands near southern range limit likely threatened by warmer climate” Credit: Pixabay/CC0 Public Domain A study published in the journal Wetlands documents an invasion happening in the Adirondacks: the black spruce, tamarack, and other boreal species are being overcome by trees normally found in warmer, more temperate forests. Ultimately, researchers from the SUNY…
“#Research suggests a better way to keep birds from hitting power lines” Device to keep birds from hitting power lines.

Suspended, rotating devices known as “flappers” may be the key to fewer birds flying into power lines, a study by Oregon State University suggests….
“#Antarctic penguins happier with less sea ice” A penguin equipped with a video camera on its back and an accelerometer on its head.

“#Cowbirds change their eggs’ sex ratio based on breeding time” A new study finds that cowbirds adjust the sex of their offspring throughout the nesting season. A female, left, and male cowbird perch on a wire fence. Both birds are adults. Credit: Photo (c) by Michael Jeffords and Sue Post Brown-headed cowbirds show a bias…
“#Economic alien plants more likely to go wild” Oxalis pes-caprae or Bermuda buttercup is native to South Africa, and has been introduced elsewhere as bee plant (for honey production) and for ornamental purposes. It is now widely naturalized elsewhere, like here on Crete (Greece). Credit: Mark van Kleunen An international team of researchers led by…
“#Jellyfish contain no calories, so why do they still attract predators?” Credit: CC0 Public Domain They contain no carbohydrates. No fats. No proteins. Not much else but water. Still, the moon jellies (Aurelia aurita) are eaten by predators in the sea; fish, crustaceans, sea anemones and even corals and turtles. Now a new study may…
“#Biomechanical analyses and computer simulations reveal the Venus flytrap snapping mechanisms” Venus flytrap with prey. Credit: Plant Biomechanics Group The Venus flytrap (Dionaea muscipula) takes only 100 milliseconds to trap its prey. Once their leaves, which have been transformed into snap traps, have closed, insects can no longer escape. Using biomechanical experiments and virtual Venus…
“#Agricultural conservation schemes not enough to protect Britain’s rarest butterflies” A wildflower-sown set-aside strip managed through an agri-environment scheme agreement. Credit: Katie Threadgill Conservation management around the margins of agriculture fail to protect butterfly species at greatest risk from the intensification of farming, a new study says. The research, from the University of York, says…
“#Long-tailed tits avoid incest by recognising the calls of relatives” Long tailed Tit on a washing line. Credit: Dave Croker/CC BY-SA 2.0 Long-tailed tits actively avoid harmful inbreeding by discriminating between the calls of close family members and non-family members, according to new research from the University of Sheffield. Inbred animals typically suffer from reduced…
