Field training: estimating insects abundance using net-sweeping technique
收藏资源简介:
- # of individual insects is discrete variable referring to the number of insects observed in the net after each trial. - # of RTUs is a discrete variable referring to the number of species of insects caught in the net after each trial. <br>The dataset was collected on Monday, September 26th at the Saywell grassland, York University. The study was conducted by a group of researchers, Feras, Jaz, Meg and William and took place between 3:45 - 5:00 pm on a rainy, cloudy afternoon with temperature of 17C.Data was collected using two tools, sweep nets and transects. In grasslands, one was to determine a distance by transects, and walk along it sweeping the net for a specified length of time, 30 seconds in this case. Both the number of insects and number of RTUs captured were recorded. This procedure was repeated 10 times (trials).<br>Hypothesis/Prediction: How wet the grassland is affected the abundance of insects. Wetter grasslands means less insects will be captured in each trial.<br><br>
