Chile
Beginning in 2006 and continuing in 2009, SciWrite studied the
causes of the virtual disappearance of submerged aquatic plants in the Carlos
Anwandter Nature Sanctuary, a Ramsar site near Valdivia, Chile. The
disappearance of the aquatic plants caused starvation and abandonment of the
sanctuary by black-necked swans and other waterbirds that fed on the plants.
These events followed followed decades of siltation that reduced the amount of
habitat for the dominant, submergent macrophyte, Egeria densa. The
ecosystem switched alternate stable states from a macrophyte/clear water state
to a phytoplankton/turbid water state. A paper with
Dr. Harding as the lead author has been by published:
Lee Harding, Julius Pretorius
and Michael McGurk 2007. Recent changes in the Rio Cruces: Comment on Mulsow &
Grandjean (2006). Ethics in Science and Environmental Politics 2007: 1-3.

Peru
SciWrite has not worked in Peru (yet). In 2005, Dr. Harding went bird- and
mammal watching in the Andes Mountains, Amazon Rainforest, coastal wetlands, and
a coastal desert.
