Article title: Floristic composition
mediates change in forage nutritive quality of Atlantic mountain grasslands after experimental grazing exclusion

Authors: Gonzalo García-Baquero, Iñaki Odriozola & Arantza Aldezabal

Location: Aralar massif, northern Iberian Peninsula.

Experiment
design: four grassland sites (blocks) were selected in the Aralar grassland system; then three
"treatments" (three levels of the fixed factor )
were

applied in each of these four
blocks. Eight forage quality variables as well as floristic composition were
measured in each Site x Treatment combination 5-6 times per year during 6
years.

This corresponds to a
repeated-measures Randomized Block Design, where is the random
factor, is the fixed factor and is the
within-block (fixed) factor.

Measured
variables:

The first three columns
(Site, Treatment, Time) specify the experiment design.The levels of the
random factor Site are Alotza, Igaratza, Oidui, and Uzkuiti.

The levels of the fixed
factor Treatment are A.Grazing, B. Cage, and C. Exclosure. Time is specified
as a quantitative (discrete) variable (1, 2, 3…),

where Time = 1 corresponds to
measurements taken in June 2005
