| Changes in vegetation shaped global temperatures over last 10,000 years Posted: 15 Apr 2022 01:38 PM PDT Follow the pollen. Records from past plant life tell the real story of global temperatures. Warmer temperatures brought plants -- and then came even warmer temperatures, according to new model simulations. |
| Rain, floods and green infrastructure: Are cities mitigating the hazards equitably? Posted: 15 Apr 2022 09:47 AM PDT New research combines demographic data with the distribution of GI and geographic areas prone to rainwater flooding in Portland, Phoenix and Atlanta and asks whether these cities are equitably building GI to mitigate flood risks. |
| US Nationwide maps of bird species can help protect biodiversity Posted: 15 Apr 2022 09:47 AM PDT Researchers have developed the maps at a fine-enough resolution to help conservation managers focus their efforts where they are most likely to help birds -- in individual counties or forests, rather than across whole states or regions. |
| Methane from waste should not be wasted: Exploring landfill ecosystems Posted: 15 Apr 2022 09:47 AM PDT Scientists explore microbial communities flourishing in leachate, a liquid percolating through solid waste in a landfill. They find that the composition and behavior of specific microbes found in arid landfills, like those in Arizona, are distinct from similar communities in more subtropical or temperate climates. Microbial composition also differs depending on the age of the landfill deposits. |
| Lost South American wildflower named 'extinctus' rediscovered (but still endangered) Posted: 15 Apr 2022 07:05 AM PDT This South American wildflower was presumed extinct -- to the point that its official scientific name is Gasteranthus extinctus. But now, scientists are reporting the first confirmed sightings in 40 years. This not only means that this one little flower made it, but that an important concept in conservation biology called Centinelan extinction needs to be re-examined. |
