Flooding Affects Fluctuating Asymmetry but not Growth of a Riparian Orbweaving Spider

This dataset is based on a mesocosm experiment investigating the impact of flood duration on spider physiology. We used the Riparian Stream Mesocosm (RSM) in Landau University, Germany, to simulate four floods between May a September 2023 of various duration. This facility comprised 16 independent mesocosms, each designed to replicate a riparian ecosystem, including both an artificial stream and its adjacent riparian area. Each artificial stream was continuously fed with water pumped from the nearby river Queich. Each mesocosm was enclosed within a 3.5 m-high greenhouse-like structure covered by 1 mm mesh gauze. We considered only the spiders exposed to the extreme treatments (e.g., Non-flooded controls and 14 days of flooding). We handpicked Tetragnatha extensa after the first and fourth flood, took picture of their heads and landmarked them using tps software. Aquatic emerging insects were also sampled during the flooding event, individual caught were then counted and identified to family. The dataset is composed of: The landmarks of the spiders head from flood 1 and 4 and the associated meta data. The emergence data
