zones, A to E. Geographical Zone F is not included because all researchers in Antarctica are from
other parts of the world. For latitudinal ranges and countries included in geographical Zones A to

ILTER publications generated in the Northern Hemisphere accounts for 94 % of
the world's total. Therefore, for ILTER ISI publications the Northern/Southern
Hemispheres ratio is even greater than 9:1.
Most LTER research outputs listed on LTER bibliographies are not published
in ISI journals (Fig.

).

It is important to note that there are an unknown number of LTER research outputs that are not
listed in bibliographies, and the national and site-level bibliographies themselves are often incon-
sistent in what they report as publications.
