  • Protecting corridors is critical to preserving genetic diversity in tigers, and mizimising...
    on January 11, 2018 at 3:14 pm

    Tigers have lost 95% of their historical range, and what remains is highly fragmented. According to a new study, high traffic roads and densely populated urban areas are a severe impediment to tiger movement between fragments. Unplanned development in the future will result in loss of connectivity and an increased possibility of extinction for several tiger populations. To ensure future persistence, tiger populations need to be managed as a network of protected areas connected by corridors. […]

  • Dead trees are alive with fungi
    on January 9, 2018 at 4:24 pm

    So far, little research has been conducted on fungi that live on dead trees, although they are vital to the forest ecology by breaking down dead wood and completing the element cycle between plants and soil. Soil biologists have now discovered that the number of fungus species inhabiting dead trees is 12 times higher than previously thought. Once trees die they are also colonized by different fungal communities depending on their species. […]

  • Amazon biodiversity hotspot to suffer even more losses after contentious law passed
    on January 8, 2018 at 5:16 pm

    In August 2017, the Bolivian government passed a contentious law that paved the way for construction of a new 190-mile road cutting through one of the country's most iconic and biodiverse protected rainforests. But a new report shows that the Isiboro-Sécure National Park and Indigenous Territory (or TIPNIS) has been subject to alarming levels of deforestation within its borders for many years, a reality that is too often overlooked.

The tree species, Pittosporum undulatum, known locally as 'mock orange', is threatening many rare and endangered species, some of which are found nowhere else in the world. Scientists are urging the relevant institutions to prioritise a program of control of this species. […]

  • Human impacts on forests and grasslands much larger and older than previously assumed
    on December 21, 2017 at 5:26 pm

    Human biomass utilization reduces global carbon stocks in vegetation by 50%, implying that massive emissions of CO2 to the atmosphere have occurred over the past centuries and millennia. The contribution of forest management and livestock grazing on natural grasslands to global carbon losses is of similar magnitude as that of deforestation. Currently, these effects are underappreciated in existing global carbon models and assessments of the greenhouse gas emissions (GHG) from land-based production. Without full consideration of land management effects, global climate forecasts and calculations of the GHG effects of future bioenergy policies are error prone, seriously jeopardizing the robust evaluation of measures that would help achieving the 1.5°C target of the Paris Agreement. […]
