<b>Prediction:</b>
It was predicted that there would be a greater abundance of insect species in
the grassland environment.

 <b>Hypothesis:
</b>The
abundance of insect species in the bright yellow coloured pan traps that are
within the grassland environment will be greater than the total number of
insects in the pale or white coloured pan traps, because the insects are more
attracted to the brightly coloured bowls compared to the pale coloured bowls.

<b>Meta-Data:</b>

<br>

<b>Number
of Pan traps :</b> The number of Pan traps
that were placed in each habitat. There were ten Pan traps that were placed in
the grassland environment and there was also ten Pan traps positioned in the
Woodlot.  In total there were twenty Pan
traps that were placed in the habitats combined and this also represents the
number of replicates that were conducted, which was n=20. This variable is continuous
since numbers were used.

<b>Colour
of Pan traps: </b>The Pan traps came in three different
colour s which were white, blue and yellow. This is a categorical variable.

<b>Type
of Habitat: </b>The experimental study was conducted in
a grassland and a woodlot. A grassland is known as an area where there is
vegetation. The other habitat which was a woodlot is a forest environment. This
is a categorical variable.

<b>Number
of Insects:</b> The total amount of insects was counted
in each Pan trap that was placed in each type of habitat. This is a continuous variable.

<b>Number
of different species (rtus):</b> The number of distinct
species that were found in the soapy water in each Pan trap. Rtus is the
abbreviated form which means different recognizable taxonomic units per sample.
This is a continuous variable.

<b>Methods:</b>

            This
experimental study was conducted on Tuesday September 27, 2016 from 2:50pm-3:50pm
in both a grassland and woodlot habitat. The location of this study was done in
Boyer Woodlot in York University campus, with a latitude of 43.8^o,
and a longitude of -79.5^o. The temperature was 21^oC, it
was partly cloudy, a wind coming from the southwest direction at 23 km/h and
the humidity was 43% in Boyer Woodlot. First the researcher went to the edge of
the grassland environment which was northwest of the Lumber building and took
ten steps forward. Then first Pan trap was positioned in the grassland
environment, and a systematic approach was used when placing the Pan traps in
the grassland environment. In between each Pan trap there was a distance of 0.5
metres, and the colour of the Pan traps were randomly placed with the order
white, blue, and yellow until ten Pan traps were placed in the grassland
habitat. Next the researcher filled each Pan trap which had a diameter of 18 centimetres
and a depth of 5 centimetres with soapy water. Each Pan trap was filled half way.
After the researcher stood at the edge of the woodlot habitat and took ten steps
forward, and then the first Pan trap was placed in the woodlot. The colours of
the Pan trap were also placed in the same order like the Pan traps in the grassland
habitat. Both of the habitats contained 4 white, 3 blue, and 3 yellow Pan
traps. Soapy water was also placed in each Pan trap where only half the volume
of the bowls were filled. Then the Pan traps in each habitat were left
untouched for an hour, the data was collected in a chart form. The number of
insects in the soapy water of the Pan traps within the grassland and woodlot
were visually observed and counted. The researcher then visually counted the
different number of species or the different recognizable taxonomic units per
sample. The different number of species that were found in this experiment
included ants, and flies which are two distinct species.

<b>预测:</b> 本研究预测草原生境中昆虫物种的丰度将更高。<b>假设：</b>草原生境内的亮黄色盘形诱捕器（Pan traps）中捕获的昆虫物种丰度，将高于浅色或白色盘形诱捕器中的昆虫总数量，原因在于相较于浅色诱捕器，昆虫对亮色碗状诱捕器的趋性更强。<b>元数据:</b> <br> <b>盘形诱捕器数量:</b> 各生境中布设的盘形诱捕器（Pan traps）数量。本研究在草原生境布设了10个盘形诱捕器，同时在林地生境（Woodlot）也布设了10个，两类生境总计布设20个盘形诱捕器，对应本次实验的重复次数n=20。该变量为连续变量，以数值形式表征。<b>盘形诱捕器颜色:</b> 本次实验使用的盘形诱捕器共有3种颜色，分别为白色、蓝色与黄色，属于分类变量。<b>生境类型:</b> 本实验设置了草原与林地两类生境：草原生境指以植被为主要覆盖的区域，林地生境则为森林环境，该变量属于分类变量。<b>昆虫数量:</b> 对每类生境中每个盘形诱捕器内的昆虫总数进行计数，该变量为连续变量。<b>不同可识别分类单元数量（RTUs）:</b> 每个盘形诱捕器皂液中发现的不同物种数量，RTUs为缩写，指代每个样本中的不同可识别分类单元，该变量为连续变量。<br> <b>实验方法:</b> 本实验于2016年9月27日星期二14:50-15:50在草原与林地两类生境中开展，实验地点位于约克大学校园内的博伊尔林地（Boyer Woodlot），地理坐标为北纬43.8°，西经79.5°。当日该区域气温21℃，天气为多云间晴，西南风风速23 km/h，相对湿度43%。研究者首先前往位于Lumber建筑西北侧的草原生境边缘，向前行走10步后启动诱捕器布设工作，采用系统布设方式放置盘形诱捕器：相邻诱捕器间距为0.5米，诱捕器颜色按照白、蓝、黄的顺序随机布设，直至完成10个诱捕器的布设。随后，研究者向每个直径18厘米、深度5厘米的盘形诱捕器中注入半量的皂液。完成草原生境的诱捕器布设后，研究者前往林地生境边缘，向前行走10步后开始布设林地组的盘形诱捕器，颜色布设顺序与草原组一致。两类生境的诱捕器配置均为4个白色、3个蓝色与3个黄色，同样注入半量皂液。将两类生境中的盘形诱捕器静置1小时后，研究者以表格形式记录实验数据：通过目视计数法统计各诱捕器皂液中的昆虫总数，并计数每个样本中的不同可识别分类单元数量。本次实验共观测到两类昆虫物种：蚂蚁与苍蝇。
