Spatial and temporal niche overlap of aardwolves and aardvarks in Serengeti National Park, Tanzania
收藏资源简介:
We collected data during August 2016–June 2018 using 106 remote cameras (Stealth Cam, model N45NG; Irving, Texas, USA). Nearest distance between cameras was 3,000 m for 63 cameras and 4,225 m for 43 cameras (Figure 1). We attached cameras to metal stakes 50-cm above ground and cleared vegetation in front of cameras. We programmed cameras to record 3-image bursts at each detection with a 30-second delay and inspected each about every 6 weeks. Because of staggered camera installations, we extracted data for a period of 70 consecutive days from each camera (hereafter a “camera-period”) during 26 August 2016–1 January 2018, and a second 70-day camera-period for 77 cameras during 22 January 2017–30 June 2018. Overlap between the two periods of data collection occurred due to staggered camera installation. Most (95%) data were obtained during September 2016–February 2018. Each 70-day camera-period was associated with a season (wet season, November-May; dry season, June-October). If a camera-period overlapped two seasons, we split the data by season into two separate, shorter camera-periods each entirely with one season.
