“…Because downstream water users rely on upstream water supply, understanding WES connectivity is equally important as well as changes in WES in specific places (Yeakley et al. ). Third, the changing value of WES over space and time will require careful examination.…”

We investigated the potential impacts of climate change on water‐related ecosystem services (WES). Based on the review of the recent literature, we concluded that climate change will have substantial effects on provisioning, regulating, and cultural WES via changes in the distribution and value of water over space and time. However, the effects of climate change on specific WES will be different depending on the extent of the impact of such changes in the distribution of water and the adaptive capacity of the region's biophysical and social system. The 2015 California drought provides an excellent example of the cascading effects of climate change on multiple WES. Declining streamflow and the concomitant rising stream temperatures have immediately threatened the provision of drinking water and hydropower generation and threatened the health of ecosystems that rely on water. The secondary effects of drought on WES are widespread across different water‐dependent industries, including water‐based recreation. The findings of our study also show that the impacts of climate change will differ by location, suggesting a need for a place‐based flexible climate adaptation strategy. We also suggest that future research directions include the examination of: (1) the multiple cascading effects of climate change on potential synergies and tradeoffs among different WES, (2) the specific effects of changing climate and the connectivity of WES from upstream to downstream WES users, (3) the changing value of WES over space and time under changing climates, and (4) the effectiveness of various climate adaptation measures on the whole suite of WES.

“…However, spatial patterns of sedimentation rates were little investigated, and interannual dynamics were not described. Today, the comprehension of spatiotemporal patterns of overbank sedimentation rates appears to be critical, especially in the context of current global change and its role in floodplain system functioning and providing ecosystem services to riverside communities (Yeakley et al, ).…”

Multi‐annual contemporary flood event overbank sedimentation rates were quantified on the World's third largest river in terms of discharge, the tropical lower Orinoco. We discuss the role of variables at the basin and reach scales that contributed to the complexity of spatio‐temporal overbank sediment deposition patterns. Monitored in situ plots were characterized by distance to the main channel, hydroperiod, different geomorphological units, and vegetation cover. Flood event sedimentation rates showed a high spatial variability ranging from the absence of sediment deposition up to 225.46 kg m‐2 yr‐1. Banks and levees received relatively high amounts of sediment (39.6 kg m‐2 yr‐1), whereas observed mean sedimentation rates on the more distant floodplain and backswamps tended to be lower (17.7 kg m‐2 yr‐1). Significant differences in sedimentation rates were observed in two major vegetation types: dense herbaceous and shrubby vegetation (42.2 kg m‐2 yr‐1) and floodplain forest (12.7 kg m‐2 yr‐1). However, overbank sedimentation patterns also reflected imbricated hydrosedimentary and biogeomorphological vegetation feedbacks that co‐construct fluvial landforms. The incidence of an El Niño–Southern Oscillation–La Niña episode during the study period on sediment availability and floodplain sedimentation suggests that within whitewater rivers, where suspended sediment concentrations are naturally high, hydrological connectivity seems to be more important for floodplain sedimentation than variations in suspended sediment concentrations. These results may provide a good basis for future biogeomorphological investigation projects using complementary methodologies, in order to better anticipate global change and fluctuations in the occurrence, strength or duration of El Niño–La Niña episodes in the tropical zone and their consequences for flood discharge and sediment dynamics during channel–floodplain exchanges.

“…Instead of a single fish or fishery focus, wise ecosystem management or ecological salmon management would consider these food web connections in setting salmon and forage fish harvest levels (Michael 1998;Cedarholm et al 1999). However, that would mean reduced commercial and recreational catch levels (Cedarholm et al 1999;Stockner 2003;Piccolo et al 2009), and thus a full accounting of ecosystem services in these river ecosystems is likely required to achieve sustainable management outcomes (Yeakley et al 2016).…”
