“…Springs are often very small ecosystems but at the same time very numerous, both regionally and globally (Glazier 2012). As an interface between aquatic and terrestrial habitats, springs harbour numerous specialized species which strongly respond to changes in water chemistry and thus the biogeo-chemistry of the catchments feeding them (Beierkuhnlein and Gollan 1999, Cantonati et al 2006, Kapfer et al 2012, Kubíková et al 2012. Among all the morphological types of springs described by Thienemann (1924), 'helocrenic' springs (seepage springs) host the most specialized and taxon-rich communities (Cantonati et al 2012a).…”

The processes underlying species' dominance patterns and community composition are insufficiently investigated for springs, yet these systems, which are believed to be very stable environments, represent an important interface between aquatic and terrestrial habitats contributing significantly to local and regional diversity. We studied the dominance patterns and plant community composition of 238 springs in Central Europe. According to the conventional ecological belief we hypothesized (1) a positive relationship between local abundance and regional distribution of spring plant species, as well as between species commonness and species' realized breadth and (2) the occurrence of oligarchic species similar to other stable environments like tropical forests. Based on previous studies on these springs, we furthermore hypothesized (3) that water pH-essentially a proxy for nutrient availability-is the major driver of spatial compositional dissimilarity, i.e. beta-diversity. We tested these three hypotheses by using species commonness estimates, realized niche space and generalized dissimilarity modelling based on hydrochemistry. In line with conventional wisdom, we report a positive relationship between local abundance, species commonness and regional distribution for the majority of the species. In contradiction to other systems, we found both specialist and generalist species to be locally dominant and regionally widespread, thus common, while species with intermediate niche breadth showed the lowest commonness values. However, we detected three oligarchic species, exceeding all other species in local abundance and regional distribution, which did not follow these relationships. Both dominance relations (oligarchy) and community composition were mainly driven by water temperature and concentration of elements related to acidity regime (Al, Cd, Ca and Mg), although much of the variation in both remained unexplained. Thus, further research should focus on biotic interactions, which are likely to be important drivers of plant community composition in springs.

“…The macroinvertebrate community may differ according to structural variables (substrate composition, food availability and flow velocity) in a small scale or can result of water limnological differences in a large scale (Kikuchi and Uieda, 1998;Melo, 2009). Moreover, abiotic variables may be divided in macro or meso spatial scale in which mesoscale can be structural and limnological with hierarchical relationship between these scales influencing organisms (Vilella et al, 2004;Kubíková et al, 2012).…”

Aim:The present study aimed to elucidate if the water physical and chemical parameters from a first order stream of Biological Reserve of Saltinho from south Pernambuco induces in the distribution and abundance of benthic macroinvertebrates. Methods: Both limnological parameters (pH-value, electrical conductivity, water temperature, turbidity, salinity and dissolved oxygen) and structural variables of aquatic habitat (substrate, food availability and flow velocity) influence the macroinvertebrates community structure. The creek is very small, with an approximate width of 1-3 m and a depth of 0.5 m. It was used a Surber sampler (100 µm) in three stretch of the creek, each one with two sampling units (s.u.) totaling six s.u. distant 50 m, with a sampling effort of five minutes per s.u.. The measurer multiparameter was used in order to obtain the water analysis (limnological parameters). Results: From 11 taxa of macroinvertebrates found no significant correlation (p<0.05) was presented with pH-value, water temperature and salinity, but some taxa showed with electrical conductivity (EC), turbidity (TD) and dissolved oxygen (DO). Hemiptera abundance increases with decreasing DO; Ostracoda abundance increases with increasing EC and TD and the decrease in DO; and Trichoptera abundance increases with the decrease in EC and TD and the increase in DO. The stretches exhibited similarity in relation to the richness and abundance of macroinvertebrates and limnological parameters. The macroinvertebrates distribution in the stream not showed the same pattern, grouping s.u. of different stretch, because the habitat structural variables influenced the distribution. Conclusions: Therefore, the macroinvertebrates community varies according to abiotic factors in different limnological and structural parameters. This study is the first record of a work that associates benthic fauna and abiotic parameters at the Atlantic forest of Pernambuco.Keywords: macroinvertebrates, abiotic variables, stream, Atlantic forest, benthic fauna.Resumo: Objetivo: O presente trabalho teve por objetivo elucidar se as variáveis físicas e químicas da água, de um riacho de primeira ordem da Reserva Biológica de Saltinho do sul de Pernambuco atuam na distribuição e abundância dos macroinvertebrados bentônicos. Métodos: Sabe-se que tanto as variáveis limnológicas (pH, condutividade, temperatura, turbidez, salinidade e oxigênio dissolvido) quanto as variáveis estruturais do habitat aquático (substrato, disponibilidade de alimento e velocidade do fluxo) influenciam na estrutura da comunidade de macroinvertebrados. O riacho é muito pequeno com largura aproximada de 1-3 m e profundidade de 0,5 m. Foi utilizado um amostrador tipo Surber (100 µm) em três trechos do riacho, cada um com duas unidades amostrais (u.a.) totalizando seis u.a. distantes 50 m, com um esforço amostral de cinco minutos por u.a.; as variáveis da água foram coletadas com o auxílio do medidor multiparâmetro de qualidade da água. Resultados: Dos 11 táxons encontrados nenhum exibiu cor...

“…Here, detritus processing takes a much longer time (Sedell et al 1974, Whiles andWallace 1997) and can be characterised as a low quality detritivore food resource (Taylor et al 1989, Klemmedson 1992, Friberg and Jacobsen 1994. Furthermore, comparing deciduous and coniferous spring microhabitats, one main conclusion is that substrate types are more important than substrate heterogeneity in contrast to a more general finding by Kubíková et al (2012). However, in this study, it is not possible to distinguish between acidification and substrate types for describing a prevailing key factor causing taxa and individuals' richness in forest spring habitats.…”

Nature Conservation 27: 85-99. https://doi.org/10.3897/ natureconservation.27.26024 AbstractHeadwater springs in the German Low Mountain Ranges are local ecotone habitats and biogeographical islands embedded in and interlinked with their adjacent landscape. The structure of forests reflects the eco-hydrological conditions in substrate type occurrence, microhabitat richness and biodiversity in forest springs. This study considers effects from different forest land cover by comparing spring habitats in deciduous beech forests and coniferous spruce forests on eco-hydrological structures and biodiversity. Study areas include six different forest landscapes in the Low Mountain Ranges in Central Germany in Hesse and Thuringia. Hydro-morphological structure mapping and invertebrate sampling was executed within a multi-habitat sampling regime, which involves sampling plots being allocated according to the cover ratio of the occurring substrata. Aquatic and terrestrial spring zones are considered with respect to an ecotone approach. Some in situ measurements were implemented, such as pH values, to assess the acidity of the spring water. Results show obvious differences in acidity, substrate type cover ratios and biodiversity in deciduous and coniferous forest springs. Conifer forest springs were found tending to acidification while deciduous forest springs were slightly alkaline. Deciduous forest springs had higher cover ratios of organic microhabitats as well as a higher biodiversity in species richness and total number of individuals. Although it was not possible to clearly distinguish one direct key factor of fauna assemblages, negative effects from forest management practices (e.g. monoculture plantations of conifer forest) on spring habitats can be concluded.
