  • Species-rich forests store twice as much carbon as monocultures
    on October 4, 2018 at 6:39 pm

    Species-rich subtropical forests can take up on average twice as much carbon as monocultures. An international research team has evaluated data from forests grown specifically for this purpose in China with a total of over 150,000 trees. The results speak in favor of using many different tree species during reforestation. […]

  • Finding middle ground on the range
    on October 1, 2018 at 5:03 pm

    Cattle ranching and conservation may seem an unusual pair in the American West, but new research reveals a clear link between the economic health of ranches and the ability to maintain habitat for an iconic wild bird that for years has been at the center of public land policy debate: the greater sage grouse. […]

  • Ancient African herders had lasting ecological impact on grazed lands
    on August 29, 2018 at 5:32 pm

    Ancient animal herders added to the ecological richness and diversity of the African savanna thousands of years ago -- an effect that persists to the present day, a new study finds. The herders' practice of penning their cattle, goats and sheep at night created nutrient-rich grassy glades that still attract wildlife and have increased habitat diversity in the region, researchers report. […]

  • How does agriculture affect vulnerable insect-eating birds?
    on August 29, 2018 at 3:56 pm

    Aerial insectivores -- birds that hunt for insect prey on the wing -- are declining across North America as agricultural intensification leads to diminishing insect abundance and diversity in many areas. A new study looks at how tree swallows' diets are affected by agriculture and finds that while birds living in cropland can still find their preferred prey, they may be working harder to get it. […]

  • Color vision makes birds of prey successful hunters
    on August 29, 2018 at 3:55 pm

    In many cases it is the color of the prey that helps predatory birds to detect, pursue and capture them. In a new study, biologists show that the Harris's hawk has the best color vision of all animals investigated to date -- and in certain situations, even better than humans. The findings may help to protect threatened birds of prey against hazards such as wind turbines and power lines. […]

  • Multiple facets of biodiversity reduce variability of grassland biomass production
    on August 28, 2018 at 3:47 pm

  • Mojave Desert birds crashed over the last century due to climate change
    on August 7, 2018 at 5:17 pm

    More than 100 years ago, biologists conducted a thorough survey of birds in the Mojave Desert. A recent resurvey shows that the species richness of the desert habitat has dropped by 43 percent over the past century, on average, at the sites revisited. The main environmental change correlated with bird decline was a decrease in rainfall caused by climate change, which suggests that temporary sources of water might help prevent further decline. […]

  • Abandoned farmlands enrich bird communities

  • Heatwave and climate change having negative impact on our soil say experts
    on August 2, 2018 at 2:23 pm

    The recent heatwave and drought could be having a deeper, more negative effect on soil than we first realized say scientists. That's because organisms in soil are highly diverse and are responsible not only for producing the soil we need to grow crops, but also provide humans with many other benefits, such as cleaning water and regulating greenhouse gas emissions. […]

  • Monsoon rains found to be beneficial to underground aquifers

  • If you build it, the birds will come -- if it meets their criteria
    on July 11, 2018 at 1:31 pm

    A new study presents a case study on how bird surveys can better inform conservation and vegetation restoration efforts. Previous conservation methods have emphasized plants as the key to recreating habitat preferred by a sensitive animal. However, this study shows that there's more to the coastal sagebrush habitat of California gnatcatchers than just having the right plants present. […]

  • Plants in Africa 'green up' ahead of rainy season
    on July 2, 2018 at 5:38 pm

    A study has shown the greening up of vegetation prior to the rainy season in Africa is more widespread than previously understood. […]

  • Palm oil: The carbon cost of deforestation
    on June 19, 2018 at 4:30 pm

    Palm oil has become part of our daily lives, but a recent study serves as a reminder that intensive farming of this crop has a major impact on the environment.
