“…For example, amphibitic Plecoptera (Stoneflies) in the Flathead River (MT) have been collected from hyporheic water at least 4.2 m below and 50 m laterally to the river [183]. These organisms return to the surface stream to emerge, mate, lay the eggs of the next generation [183,184], and are a source of food for fishes and riparian birds and bats. Hyporheic zones may also serve as refugia for benthic macroinvertebrates during high [185] and low [186] flow events and surface water-subsurface water connections are often associated with fish spawning locations [187,188].…”

Abstract:The southern United States is characterized by a humid, subtropical climate and consists of 16 states (Texas, Oklahoma, Arkansas, Louisiana, Mississippi, Tennessee, Kentucky, Alabama, Florida, Georgia, South Carolina, North Carolina, Virginia, West Virginia, Delaware, and Maryland) and Washington DC. Currently this region is experiencing the largest net population growth in the U.S. Over the last century, the expansion of large urban centers and impervious area in the region has altered the hydrologic cycle. This review synthesizes regional research that shows how watershed hydrology, groundwater recharge, stream geomorphology, climate, biogeochemistry, and stream ecology have been affected by urbanization and the expansion of watershed impervious area.

“…Such conditions are most prevalent in anabranched rivers with alluvium dominated by gravel and cobble. In these rivers, hyporheic zones are especially expansive [e.g., Stanford et al, 1994;Jones et al, 2007], and hyporheic flow paths commonly range in length from meters to kilometers [Poole et al, 2008].…”

[1] We monitored summertime base flow water temperatures of hyporheic discharge to surface water in main, side, and spring channels located within the bank-full scour zone of the gravel-and cobble-bedded Umatilla River, Oregon, USA. Diel temperature cycles in hyporheic discharge were common, but spatially variable. Relative to the main channel's diel cycle, hyporheic discharge locations typically had similar daily mean temperatures, but smaller diel ranges (compressed by 2 to 6°C) and desynchronized phases (offset by 0 to 6 h). In spring channels (which received only hyporheic discharge), surface water diel cycles were also compressed (by 2 to 6°C) and desynchronized (by À4 to 6 h) relative to the main channel, creating diverse daytime and nighttime mosaics of surface water temperatures across main, side, and spring channels, despite only minor differences (<1°C) in daily mean temperatures among the channels. The river's hyporheic zone received and stored heat from the channel, yet hyporheic return flows carried heat back to the channel minutes to months after removal. Associated surface water temperature dynamics were therefore complex. Hyporheic discharge was not simply ''cooler'' or ''warmer'' than main channel water. Instead, instantaneous temperature differences between channel water and hyporheic discharge typically arose from diel temperature cycles in hyporheic discharge that were buffered and lagged relative to diel cycles in the main channel.

“…Due to the transition between terrestrial and aquatic zones, springs can be considered as patchy, highly structured multiple 3-way ecotones which create interfaces to groundwater and surface water (Townsend, 1989;Roca & Baltanás, 1993;Cantonati et al, 2006;Scarsbrook et al, 2007;Gerecke et al, 2011). Combining many different microhabitats and substrate types, springs are hot spots of structural and biotic diversity where groundwater species mix with surface water biota and terrestrial or wetland taxa (Illies & Botosaneanu, 1963;Stanford et al, 1994;Ferrington, 1995;Hahn, 2000;Hoffsten & Malmqvist, 2000). In addition, surface water and neighbouring terrestrial ecosystems also control springs, thereby creating a three-way zone of interaction (Scarsbrook et al, 2007;Pokorny et al, 2010).…”

Which factors shape macrozoobenthic communities in tufa springs? Results from Austrian meteogene travertine-depositing sites

et al. 2017

By studying 14 travertine-depositing springs all over Austria, we hypothesized the existence of (1) key elements of the physical and chemical template ultimately defining the structure of macroinvertebrate taxa composition and (2) a specific, travertine-associated macrozoobenthic taxa community in an environment shaped by ongoing deposition of calcium carbonate and the ever-changing limestone structures thereby created. For testing these hypotheses, we measured 29 geological and limnochemical parameters and collected benthic macroinvertebrates on travertine, coarse and fine particular organic matter microhabitats in a spring and autumn sampling run. The results identified four parameters significantly shaping taxa composition: sinter coverage, total phosphorous, oxygen concentration and the Langelier saturation index. The macroinvertebrate community was predominantly composed of stygobiontic taxa from groundwater refugia and of immigrated generalists that prefer the stable conditions offered in spring habitats. We found only few species and specialists separating study sites, the majority being well-known spring-and headwater-dwelling species without adaptation to high carbonate precipitation or association with travertine. Nonetheless, carbonate precipitation leads to higher structural heterogeneity and provides a range of new niches, which contribute to broader ranges of taxonomic diversity.
