Looking across a landscape, river networks appear deceptively static. However, flowing
streams expand and contract following ever-changing hydrological conditions of the …

Dynamic changes in the active portion of stream networks represent a phenomenon
common to diverse climates and geologic settings. However, mechanistically describing …

Intermittent rivers, those channels that periodically cease to flow, constitute over half of the
total discharge of the global river network and will likely increase in their extent owing to …

Non-perennial river segments—those that recurrently cease to flow or frequently dry—occur
in all river networks and are globally more abundant than perennial (always flowing) …

In the majority of existing studies, streams are conceived as static objects that occupy
predefined regions of the landscape. However, empirical observations suggest that stream …

Intermittent streams comprise much of the global river network, and are expected to become
more prevalent with climate change. Characterizing the expansion and contraction of …

The growing interest in combining spatial and temporal patterns in nature has been fostered
by the current availability of high‐frequency measurements. However, we still lack a …

Temporal variations in the configuration of the flowing portion of stream networks are
observed in the large majority of rivers worldwide. However, the ecological implications of …

Non‐perennial streams have a global prevalence, but quantitative knowledge of the
temporal dynamics of their flowing length—namely the extent of the wet portion of the stream …

In spite of the prevalence of temporary rivers over a wide range of climatic conditions, they
represent a relatively understudied fraction of the global river network. Here, we exploit a …
