The grid layout was -300 x 300 m with 18 plots located in the tussock
grassland catchment and 22 plots in the pine forest catchment (Fig.
For that, two criteria of pasture evaluations were used to define the forage mass available for the animals (FMa, kg DM [ha.sup.-1]): forage mass above eight cm (FM8kg DM [ha.sup.-1]) in the lower stracta (sites with presence of prostrate species without presence of tussocks
) (GONCALVES et al., 2009) and 50% of the leaf blades mass of tussocks
(LBMt, kg DM [ha.sup.-1]).
On the right-hand side, the driest areas were assembled by highest correlation with the non-tussock hemicriptophytes and autochoric (FG1), tussock
hemicriptophytes (FG4) and geophytes (FG5).
The role of grass tussocks
as shelter for invertebrates has long been documented (Pearce 1948; Luff 1966).
The description of the caterpillars was consistent with the white-marked tussock
moth caterpillar (Orgyia leucostigma) (Figure), which ranges through much of the eastern United States and as far west as Texas and Colorado.
The more detailed purpose was to determine the relationships between vascular and moss species coverage, water table position and its seasonal fluctuations, water pH and electrical conductivity (EC), and litter, but also microtopography (coverage and height of tussocks
) and coverage of Molinia caerulea.
The development of the tussock
architecture in Spartina argentinensis Parodi (Poaceae: Chlorideae) is analyzed.
Rabbits are destroying the tall tussock
grass that regulates the temperature of the nesting burrows and also provides critical cover from predators.
It took us just over 20 minutes to drop down out of the high country to the edge of the snow line where patches of tussock
grass became visible, protruding through the ice.
Hoping to halt aerial pesticide spraying designed to kill the native tussock
moth, which attacks evergreens (including Christmas trees), activists pointed out that the U.S.
Creek site was located 20 km north-east of Invercargill.
Although the K-II centrifuge has not thus far been automated for totally remote operation, including cleaning between runs, this is not an overwhelming problem and should involve cascaded centrifuges, as was done for the mass isolation of Tussock
moth polyhedral inclusion bodies (15).
