“…The high macroinvertebrate variability observed among our study wetlands may be due to factors acting at local scales (e.g., morphometry, foodwebs, geomorphic setting, water chemistry, hydrology). Winter (1977), Rochelle et al (1989), Kratz et al (1997), Riera et al (2000) reported that although neighboring lacustrine wetlands share a common climate, geologic setting, and regional species pool, they may differ in terms of their hydrology and geomorphology.…”

The main goals of this study were: (1) test how beta diversity of aquatic macroinvertebrates varies among samples from different spatial scales in permanent and intermittent wetlands; and (2) test how beta diversity of aquatic macroinvertebrates varies among different wetland habitat types. Four collections were carried out over 1 year in 16 freshwater coastal wetlands in southern Brazil. The habitat types identified were: 1) hydrophytes, represented by submersed and floating plants; 2) reed-like emergent plants; and 3) leafy emergent plants. Additive partitioning of diversity was used to decompose the total variation in macroinvertebrate composition (regional diversity) into alpha (fine spatial scale) and beta components (intermediate and broad spatial scales). A total of 51,290 macroinvertebrates distributed among 63 families were collected. Additive partitioning of diversity showed similar patterns for both permanent and intermittent wetlands. In general, alpha diversity component was much lower than beta components. The beta diversity was greater among wetlands than among distinct habitats within wetlands. We found a strong evidence of scale dependence on diversity partitioning of macroinvertebrate communities, with beta diversity at broad spatial scale making a large contribution to total diversity in coastal wetlands of southern Brazil.

“…Other statistical analyses of large regional data sets have shown significant relationships between streamwater chemistry and some complex environmental factors, such as altitude and relief [24,32], catchment size [37], glacial influence [10,27], soil base saturation [5], land use [15] or some combination of these factors [11,12,19,21,22,31,34]. Surprisingly, the primary effect of precipitation amount was not often directly highlighted [16,36].…”

-The influence of sandstone composition, precipitation, vegetation and relief on streamwater composition at base flow was studied in 95 forested catchments located in the sandstone part of the Vosges Mountains (N.E. France). Catchments lie on four main types of sandstone. Information was acquired for each catchment using a geographic information system (GIS) and spatially distributed databases. Sulphate concentration is mainly negatively correlated to the annual rainfall and positively to the relative area covered by conifers in the catchment. Nitrate is positively correlated to altitude. Sodium, Cl and Si concentrations are strongly inter-correlated and negatively related to the annual precipitation and the relative area of the conglomerate layer in the catchment. Calcium, Mg, ANC (Acid Neutralising Capacity) and pH are negatively correlated to precipitation, and positively correlated to the relative area of the sandstone layer containing dolomitic nodules. This study emphasizes the role of annual rainfall amounts in controlling stream chemistry at base flow.streamwater / acidification / spatial analysis / Vosges / sandstone Résumé -Facteurs environnementaux influençant la composition chimique des eaux sur substrats gréseux dans les Vosges. L'influence de la composition chimique des grès, des précipitations, de la végétation et du relief sur la composition chimique des ruisseaux en étiage a été étudiée dans 95 bassins versants des Vosges en utilisant un système d'information géographique (SIG) et des bases de données géo-référencées. La concentration en sulfates est corrélée négativement avec les précipitations moyennes annuelles et positivement avec la surface relative couverte par les résineux dans le bassin. Les nitrates sont positivement corrélés avec l'altitude. Le sodium, le chlorure et la silice sont fortement inter-corrélés et sont négativement liées aux précipitations et à la surface relative du conglomérat dans le bassin. Le calcium, le magnésium, l'ANC et pH sont négativement corrélés aux précipitations, et positivement corrélés avec la surface relative occupée par le grès de Senones, qui contient des nodules dolomitiques. L'étude souligne le rôle des précipitations annuelles sur la composition chimique des eaux en étiage. chimie des eaux / acidification / analyse spatiale / Vosges / grès

“…This may be due to the influence of various other catchment features not included in the present study, but which previous studies have reported to influence surface water chemistry. For example, slope will mediate the relationship between catchment characteristics and surface water quality due to its influence on surface runoff (Rochelle et al, 1989) as well as being a predictor of soil organic horizon depth (Rasmussen et al, 1989) and wetland abundance (Eckhardt and Moore, 1990). The development of a particular soil type reflects a number of factors including climate, parent material, topography and vegetation and is reported to be a crucial factor in determining surface water composition and quality (Aitkenhead et al, 1999;Billett and Cresser, 1992;Hope et al, 1997).…”

Numerous catchment characteristics including topography, geology, soil and vegetation are reported to exert a strong influence on mean surface water properties. The present study employs a geographical information system (GIS) approach to examine, for the first time, the relationship between reservoir water quality [dissolved organic carbon (DOC) concentration, colour, nitrate concentration and pH] and catchment Phase 1 Habitat coverage. Analysis was conducted on two occasions and at two different spatial scales. Numerous statistically significant correlations were identified, suggesting the use of Phase 1 Habitat data could help improve predictive models of surface water quality. The occurrence and strength of correlations varied seasonally in response, we argue, to temporal variations in hydrological regime and anthropogenic activity. The data also suggest that the proximity of habitat types to the reservoir is significant in affecting reservoir water quality. The findings are used to recommend suitable measures for drinking water companies to mitigate against water quality issues.
