Contoh heather

• Few larvae were found in dew droplets or concealed within heather leaflets; most larvae were recovered from the plant surface.

• They vary from heather moorland to agrostis pastures invaded by gorse and bracken.

• This may be particularly important since heather is a structurally complex plant.

• The percentage cover of grasses, bracken, heather, and moss was estimated using ten randomly positioned 0.25 m2 quadrats.

• This should reduce the possible variability associated with heather stand age and the actual amount of heather present in the vegetation.

• However, all the seedbank data were derived from sites where heather was the dominant species, usually in the mature phase.

• All three figures were estimated from stands of mature heather with c. 100% cover.

• As he says, 'many a heather-covered hillside is a gravestone to a once awe-inspiring volcano'.

• To examine whether larval migration was as efficient on heather as on a monocotyledon or on a structurally simple dicotyledon we undertook a second experiment.

• Significantly more larvae of both nematode species were recovered in the region of the heather than the grass or controls.

• In the first group of eight trays, five heather stems were planted at distances 2, 4, 6, 8 and 10 cm from the centre.

• The highest numbers were recovered from the heather stems; the lowest numbers were recovered from the wheat stems (fig. 3).

• After constant exposure, significantly more larvae were recovered from heather than from either of the control plants.

• The heather stems had been trimmed so that each had a vertical stem that extended 7 cm above the soil surface.

• This implies that the structural complexity of heather causes no problems for the infective larvae.
