photo - two local men on a beached boat now far from the water, "These men once relied on the Aral Sea. Today, the dry land is a reminder of lost livelihoods"

maps - total dust emissions over Central Asia for the DUBLT
simulation year of 30th March 2015 - 29th March 2016, for (a)
the ‘present’ surface water coverage, and (b) the ‘present’ - ‘past’
dierence. The black boxes indicate areas discussed in the text,
clockwise from north to west: the Aralkum, the Kyzylkum, the
Karakum, and the Garabogazköl Basin.

maps - Yearly mean PM10 values (a) from dust emitted by the Aralkum. The WHO’s guidelines recommend upper limits of 15 micro grams / m³ on the yearly average, and 45 micro grams / m³ on the daily average. Plotted in panel (b) are the numbers of days which exceed this daily average threshold of 45 micro grams / m³

“HIGHLIGHTS:
• Deadwood volumes and types were measured at beaver-created flooded forest sites.
• Significant amounts of rare deadwood types are produced at the sites.
• Beaver-created flooding occurs in areas otherwise rarely experiencing disturbances.
• Beavers are an economic option for riparian forest and wetland restoration..."
