Flow pulses shape periphyton differently according to local light and nutrient conditions in experimental lowland streams

Abstract: Streams generally are affected by multiple stressors acting at different timescales. Periphyton, often the most important primary producer in these ecosystems, may respond to short‐term impacts as well as to different long‐term environmental conditions with potentially various changes in community structure. Here, we experimentally investigated the effects of sudden flow pulses on periphyton communities as a way to mimic extreme precipitation events in lowland streams that are predicted to occur more often wit… Show more

“…Furthermore, our samples were collected during the dry season, where diminished rainfall may reduce lateral inputs of nutrients from the pasture to the stream. In deforested reaches, light availability commonly acts as a driving force on periphyton algal growth (Calvo et al, 2022), influencing its response to nutrient availability (Johnson et al, 2009). This suggests that a low contribution of phosphorus coming from the pasture combined to a higher light availability may have led to a P limitation in algal growth within the pasture reach.…”

“…Periphyton productivity is influenced by various factors such as herbivory, flow velocity, light availability, and nutrient levels (Lourenço-Amorim et al, 2014;Calvo et al, 2022). While forested reaches typically exhibit low periphyton productivity due to shading, deforested areas are characterized by increased algal biomass, with limitations imposed by nutrient availability, water velocity, or herbivory (Tromboni et al, 2019).…”
