Stream drying is increasing globally, with widespread impacts on stream ecosystems. Here, we investigated how the of ecosystem connectivity might depend network size and location within network. Using 11 networks from across United States, simulated scenarios in which varied spatial extent drying. We found that rate loss size, such larger lost more rapidly than smaller networks. also When occurred mainstem, even small amounts resulted rapid losses connectivity. headwater reaches, had little impact Beyond a certain threshold, however, declined further increases Given worldwide, our findings underscore need for managers to be particularly vigilant about fragmentation when managing at large scales occurs mainstem reaches.
