I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Coastal development, changing climate threaten sea turtle nesting habitat” Ocean waves cover a sea turtle nest in Fort Lauderdale, Florida. Florida State University researchers found that sea-level rise is projected to submerge about 80 percent of current nesting habitat that is predicted to have a suitable climate for future egg incubation. Rising sea levels, a…
“#Study shines new light on how young tree seedlings develop” A seedling used in the study. Credit: UGA The first few weeks of a tree seedling’s life can be the most precarious. As it pushes thin new roots into the ground it’s also reaching up with tiny new leaves. Water and energy are precious. Most…
“#High human population density negative for pollinators” Credit: CC0 Public Domain Population density, and not the proportion of green spaces, has the biggest impact on species richness of pollinators in residential areas. This is the result of a study from Lund University in Sweden of gardens and residential courtyards in and around Malmö, Sweden. The…
“#Toronto seeks to save oak tree older than Canada” An oak tree estimated to be about 300 years old, or twice as old as modern Canada itself, is seen on July 12, 2020 in North York, Ontario In the shadow of Canada’s largest cluster of skyscrapers, Toronto is looking to preserve a majestic, centuries-old oak…
“#Habitats for endangered green sea turtles will be federally protected in Florida” An olive ridley sea turtle, a species of the sea turtle superfamily.

The research team based in Japan published their analysis…
“#Fossil pollen record suggests vulnerability to mass extinction ahead” Postdoctoral Fellow Yue Wang and Assistant Professor Jenny McGuire are studying pollen sample data from across the North American continent to develop improved strategies for conserving biodiversity. Credit: Allison Carter, Georgia Tech Reduced resilience of plant biomes in North America could be setting the stage for…
“#Ecologists put biodiversity experiments to the test” Aerial view of the Jena Experiment. Credit: Jena Experiment Much of our knowledge of how biodiversity benefits ecosystems comes from experimental sites. These sites contain combinations of species that are not found in the real world, which has led some ecologists to question the findings from biodiversity experiments….
“#Tropical songbirds stop breeding to survive drought” Credit: Pixabay/CC0 Public Domain Songbirds in tropical rainforests curtail their reproduction to help them survive droughts, according to a study Monday. Species with longer lifespans were better able to cope with this environmental volatility than previously thought, researchers found. With more record hot spells gripping parts of the…
“#Nooks, crannies and critters: Researchers develop new way to measure complexity of habitats” A diver swimming with camera gear over the reef to measure three-dimensional complexity at Lizard Island on the Great Barrier Reef, Australia.
