“…First, substrate has been widely identified as one of the most important variables explaining the presence and abundance of benthic macroinvertebrates on a micro scale (Beisel et al, 1998). Macroinvertebrates are typically associated with certain substrates due to various morphological and physiological adaptations (Pardo and Armitage, 1997) as analysed in previous studies (e.g., Schröder et al, 2013), since they provide important requisites such as shelter, food and reproduction.…”

“…However, the fine-scale structure can act as an important factor for the distribution of gastropod grazers (Clampitt, 1973;Hoffman et al, 2006) and other epilithic invertebrates (e.g. Bivalvia, Ephemeroptera, Trichoptera) (Schröder et al, 2013). Clifford et al (1989) and Clifford et al (1992) showed that nymphs of Epeorus spp.…”

a b s t r a c tFreshwater snails are widely distributed in running water systems. Most of them are feeding on biofilms attached to substrata. We used gastropods with different morphology and potentially different traits to analyse the effect of water currents and substratum roughness on the interactions between grazers and biofilms. The gastropods were exposed to naturally grown biofilms from the River Rhine that differed in age and in their artificial substratum roughness (mimicked by abrasive paper). The experiments were conducted in endless channels with paddle wheels where the current velocity could be set steplessly. The freshwater pulmonates Ancylus fluviatilis and Physella acuta as well as the freshwater prosobranchs Bithynia tentaculata and Potamopyrgus antipodarum were used as model organisms in this investigation. The time the snails remained on the test area related to the substratum roughness, and current velocity was used to compare the performance of the four snail species on different aged biofilms. In one experiment, the locomotive activity of snails was traced.Gastropods left substrata without biofilms and did not show different responses to biofilms of diverse ages with significant differences in their biochemical contents. Grazing by snails altered the biofilms in their chlorophyll-a content, ash-free dry mass, and ash mass. A current velocity above 0.12 m s −1 drove B. tentaculata, P. acuta, and P. antipodarum off the test areas, only A. fluviatilis remained unaffected by the applied current velocities (up to 0.23 m s −1 ). The substratum roughness had no direct influence on the retention time of snails and their locomotive activity on the substrata, whereas the chlorophyll-a content of the biofilm strongly influenced snail activity. Substratum roughness had only an indirect influence on the behaviour of snails contrary to studies on marine snail species.

“…Several benthic invertebrate species develop various morphological and physiological adaptations strongly associated with habitat conditions and thus can depend on the type, composition and size of the substrate for their distribution in streams (Schröder et al, 2013). The substrate size can vary from larger and more complex, such as pebbles, leaves and woody materials that support a great diversity and abundance, to fine sediments like sand, with few species (Kikuchi and Uieda, 2005).…”

Does the habitat structure control the distribution and diversity of the Odonatofauna?

The statement that the habitat complexity and structure govern the abundance and diversity of biological communities has been widely investigated. In this context, we assumed the hypothesis of habitat heterogeneity, that is, the higher habitat complexity leads to greater diversity of Odonata. In addition, we analyzed the influence of habitat structure on the distribution of this community, and evaluated the effects of abiotic variables. Odonata larvae were collected with sieves and by electrofishing in ten neotropical streams belonging to the Pirapó River basin. Forty species of Odonata were registered, which were distributed in eight families, Libellulidae stood out with the highest richness. The high gamma diversity and distribution of Odonata were associated with habitat heterogeneity in these streams. However, the abiotic variables also seem to affect the distribution of Odonata species, in view of the impact of the land use in the vicinity of streams.Keywords: insect, habitat heterogeneity, structural complexity, streams.A estrutura do habitat controla a distribuição e diversidade da Odonatofauna?Resumo O fato de que a complexidade e estrutura de habitat são reguladores da abundância e diversidade de comunidades biológicas tem sido amplamente investigada. Neste contexto, assumimos a hipótese da heterogeneidade de habitat, ou seja, maior complexidade de habitat conduz a maior diversidade de Odonata. Além disso, foi analisada a influência da estrutura do habitat sobre a distribuição desta comunidade, além de avaliar os efeitos das variáveis abióticas. As larvas de Odonata foram coletadas com peneiras e através da pesca elétrica em dez riachos neotropicais pertencentes à bacia hidrográfica do rio Pirapó. Foram registradas quarenta espécies de Odonata, distribuídas em oito famílias, Libellulidae destacou-se com maior riqueza. A elevada diversidade gama e distribuição de Odonata foram associadas à heterogeneidade de habitat presentes nestes riachos. No entanto, as variáveis abióticas da água parece também ter efeito sobre a distribuição de espécies de Odonata, tendo em vista o impacto do uso do solo dos riachos.Palavras-chave: insetos, heterogeneidade de habitat, complexidade estrutural, riachos.
