Riparian Vegetation Structure Influences Terrestrial Invertebrate Communities in an Agricultural Landscape
Water, 2021Co-Authors: Cristina Popescu, Mihaela M. Oprina-pavelescu, Valentin Dinu, Constantin Cazacu, Francis J. Burdon, Marie Anne Eurie Forio, Benjamin Kupilas, Nikolai Friberg, Peter Goethals, Brendan G. MckieAbstract:Stream and terrestrial ecosystems are intimately connected by Riparian zones that support high biodiversity but are also vulnerable to human impacts. Landscape disturbances, overgrazing, and diffuse pollution of agrochemicals threaten Riparian biodiversity and the delivery of ecosystem services in agricultural landscapes. We assessed how terrestrial invertebrate communities respond to changes in Riparian Vegetation in Romanian agricultural catchments, with a focus on the role of forested Riparian buffers. Riparian invertebrates were sampled in 10 paired sites, with each pair consisting of an unbuffered upstream reach and a downstream reach buffered with woody Riparian Vegetation. Our results revealed distinct invertebrate community structures in the two site types. Out of 33 invertebrate families, 13 were unique to either forested (6) or unbuffered (7) sites. Thomisidae, Clubionidae, Tetragnathidae, Curculionidae, Culicidae, and Cicadidae were associated with forested buffers, while Lycosidae, Chrysomelidae, Staphylinidae, Coccinellidae, Tettigoniidae, Formicidae, and Eutichuridae were more abundant in unbuffered sites. Despite statistically equivocal results, invertebrate diversity was generally higher in forested Riparian buffers. Local Riparian attributes significantly influenced patterns in invertebrate community composition. Our findings highlight the importance of local woody Riparian buffers in maintaining terrestrial invertebrate diversity and their potential contribution as a multifunctional management tool in agricultural landscapes.

diminished groundwater recharge and circulation relative to degrading Riparian Vegetation in the middle tarim river xinjiang uygur western china
Hydrological Processes, 2009Co-Authors: Zhonghe Pang, Tianming Huang, Yaning ChenAbstract:Riparian Vegetation in the middle Tarim River is being degenerated, and groundwater in the Riparian system is a key factor controlling this process. Vegetation degeneration is related to the reduced inflow from the upstream, reduced recharge to Riparian groundwater, lowered water table and increased salinity of the groundwater system. Systematic chemical and isotopic sampling of river water and groundwater transects perpendicular to the river show that Riparian groundwater is fed by the river. River water picks up salts from the river bed and/or from irrigation returns as it flows downstream, and groundwater from riverbank sediments mirror this pattern. Mineral dissolution and evapotranspiration are the main mechanisms of salt accumulation in groundwater. Reduced recharge from the river has resulted in a distinctive zoning pattern in groundwater salinity. Groundwater residence times derived from tritium contents indicate that the extent of modern recharge (since the 1960s) is limited to approximately 1500 m from the riverbank in the middle reaches of the Tarim River. Vegetation grows better in habitats with modern groundwater than in other areas. The embankment built in 2001 along one side of the Tarim River appears to have reduced groundwater recharge, causing the water table to drop and ecosystem to degenerate.

response of Riparian Vegetation to water table changes in the lower reaches of tarim river xinjiang uygur china
Hydrogeology Journal, 2008Co-Authors: Yaning Chen, Zhonghe Pang, Yapeng Chen, Weihong Li, Changchun Xu, Xiang Huang, Tianming Huang, Zhaoxia YeAbstract:The lower reaches of Tarim River in the Xinjiang Uygur region of western China had been dried out for more than 30 years before water began to be diverted from Konqi (Peacock) River via a 927-km-long channel in year 2000, aimed at improving the Riparian ecological systems. Since then, eight intermittent water deliveries have been carried out. To evaluate the response of Riparian Vegetation to these operations, the groundwater regime and Vegetation changes have been monitored along the 350-km-long stem of the river using a network of 40 dug wells at nine transects across the river and 30 Vegetation plots at key sites. Results show that the water table rose remarkably, i.e. from a depth of 9.87 m before the water delivery to 3.16 m after the third water delivery. The lateral distance of affected water table extended to 1,050 m from the riverbank after the fourth water delivery. The Riparian Vegetation has changed in composition, type, distribution, and growing behavior. This shows that the water deliveries have had significant effects on restoration of Riparian ecosystems.
