<p>Community matrix for avian point
count data (Sp.Matrix.point1) and mist-net data (Sp.Matrix.Mist) containing
species names and avian abundance for each point count station/transect.
</p>
<p><b>Sp.Matrix.point1:</b> Column 1
are the different point-count stations numbered 1-108 (1-48 are in unlogged
forests, 49-72 are in naturally regenerating logged forests, 73-108 are in
restored logged forests). Row 1 are the scientific names for the avian species
and below them are the abundances or absences (0) of the species that occur at
the different point-count stations.</p>
<p><b>Sp.Matrix.Mist:</b> Column 1
are the different transects with names UL in unlogged forests, NR in naturally
regenerating logged forests and R in restored logged forests. Row 1 are the
scientific names for the avian species and below them are the abundances or
absences (0) of the species that occur at the different transects.</p>
<p><b><u>Data collection method:</u></b></p>
<p>Two
avian communities (<b>overall bird
community, understorey bird community</b>) were sampled in 3 habitat types
(unlogged forests, naturally regenerating logged forests, restored logged forests)
in the lowland dry dipterocarp forests of the one million hectare Yayasan Sabah
(YS) logging concession in Sabah, Malaysian Borneo. Data for both communities were
extracted from Ansell <i>et al</i>. (2011)
and Edwards <i>et al</i>. (2013, 2014a). </p>
<p><b>Overall
bird community (Point Count Data):</b> Point count surveys with unlimited-radius
were conducted from May – September 2008 and May – June 2009. At sites created
within each habitat type, we sampled 12 point-count stations per site with each
station separated by 250 m (48 point-count stations in unlogged forests, 24 in
naturally regenerating forests, and 36 in restored forests). Point-count
surveys occurred for 15 minutes on three consecutive days from 0545 – 1000 h.
Each site was only sampled in one year, and any temporal effects (within or
between years) were minimized by rotating sampling between the different
habitat types. The highest number of individual birds recorded for a certain
species on any of the three days was taken as our estimate of maximum abundance
but not the species’ true abundance, which is unknown. All point counts were
conducted by a single experienced observer (D. P. Edwards) to minimise the
potential for observer bias. </p>
<p><b>Understorey
bird community (Mist Net Data):</b> Mist netting was conducted
from June – October 2007, May – September 2008 and May – July 2009. Fifty-four
transects were created (18 transects in unlogged primary forests, 18 in
naturally regenerating logged forests and 18 in restored logged forests) with
transects within each habitat placed at least 500 m apart. Each transect
contained 15 mist nets (12 x 2.7 m; mesh size 25 mm) placed end to end.
Sampling occurred for three consecutive days from 0600 – 1200 h. Each site was
only sampled in one year, and any temporal effects (i.e., within or between
years) were minimized by rotating sampling between the different habitat types.
To ensure that individual birds were sampled only once, each bird was marked
with a uniquely numbered metal leg ring. Totalling the unique individuals of
each species across the three sampling days gave an estimate of maximum
abundance, but not a species’ true abundance, which is unknown. </p>
