<p class="MsoNormal" style="background:white"><span style="font-size:12.0pt;font-family:"Times New Roman",serif;color:#222222">Many ambush predators attack prey using rapid strikes, but these strikes are typically only anteriorly directed. However, a predator
may attack laterally and posteriorly oriented prey if it can couple the strikes with rapid body reorientation. I will show that the flattie spiders attack prey throughout their entire peripheral range using rapid strikes. These spiders ambush with radially
oriented, long, laterigrade legs in a ready-to-fire status. I will present how these legs are used to generate by far the fastest turning movements in legged animals.

<p class="MsoNormal" style="background:white"><span style="font-size:12.0pt;font-family:"Times New Roman",serif;color:#222222">We used machine learning techniques to interpret soil moisture across a small watershed at the Merced Grassland and Vernal Pools Reserve,
CA from multi-spectral images and high-resolution terrain models collected by unmanned aerial vehicles (UAV) remote sensing. In addition to developing model to predict high-resolution soil moisture maps, we identify important meteorological and topographic
variables that influence soil moisture dynamics at the watershed scales. This research shows the possibility of using UAV to monitor soil moisture in rangeland environments. The findings will be useful in informing watershed management.
