A total of 155 plant taxa was identified from the sampled quadrats
for all study sites.
The database did not indicate the absence of canopy in quadrats
where there was no canopy.
As for the roller chain method, this procedure was repeated for three transects per quadrat
, which were averaged to provide a single mean value for each quadrat
were inexpensive and easy to construct.
Seven sample quadrats
were taken randomly and decided the species area curves of the vegetation of Yemrehane Kirstos Church Forest.
Coverage was calculated as an average of the percentage coverage estimated in quadrats
[adapted from Parada et al.
within the entire 200 m reach, extending across the entire width of the river for the length of the survey area.
Possible covariates that could be predictors of abundance were depth of the measurements, date, site effect (UPJP versus UPR), type of collection gear or net effect (quadrat
, aquarium net, small plankton net, and large plankton net).
Each transect line was then divided into three quadrats
that measure 50m x 50m each.
There is only one study comparing sampling methods in caves (WEINSTEIN; SLANEY, 1995) and, in this case, the quadrat
sampling method has not been assessed.
To evaluate the suitability of using quadrats
, a continuous belt transect survey was conducted using a 0.5 X 0.5-m quadrat
along the pre-established 100-m transects running at right angles to the shore (Fig.
On July 30th, the Bay Head Shores site was surveyed again using the quadrat
method described above.
