“…que contribuíram para a regressão positiva obtida neste estudo. Estes táxons costumam apresentar elevada riqueza nos ecossistemas de água doce e, em particular, na fauna fitófila (LEARNER et al, 19 8;PINDER, 1986;RODRIGUES et al, 2013), sendo também dominantes em bancos de macrófitas aquáticas (PEARSON;MATTHEWS, 1995;TRIVINHO-STRIXINO et al, 2000;KOUAMÉ et al, 2011;MARTINS et al, 2011) onde encontram boa disponibilidade de recursos alimentares na forma de detritos orgânicos aderidos às raízes. Outras variáveis ambientais da lagoa, como, por exemplo, maior adensamento das macrófitas, proximidade das raízes do vegetal com áreas de águas abertas ou fechadas e modi cações da profundidade da lagoa, poderiam também ter in uenciado na distribuição desta macrofauna entre as raízes, contribuindo para diferentes distribuições de riqueza (SYCHRA et al, 2010).…”

Resumoacró tas aquáticas desempenham um importante papel na estruturação de comunidades dos ecossistemas de aquáticos. No presente estudo, a abundância e a riqueza da comunidade de macroinvertebrados foram comparadas através de correlação simples e da participação relativa média com o volume de raízes de Eichhornia azurea numa lagoa marginal no Pantanal ( S) no período de seca. s macroinvertebrados foram identi cados até o menor nível taxonômico possível e os volumes das raízes obtidos pelo método de deslocamento de volume. Foram identi cados 21 táxons pertencentes a 13 famílias num total de 3 1 exemplares. Chironomus sp. (Chironomidae), Slavina sp. e Dero sp. (Naididae), todos detritívoros, foram mais representativos. Houve correlação positiva entre o volume das raízes com a abundância e riqueza de macroinvertebrados. Embora a análise de variância não tenha mostrado diferenças signi cativas entre riqueza e abundância da macrofauna e o volume das raízes, observou-se uma tendência de aumento de ambas as variáveis com o aumento do volume das raízes. Assim, as raízes maiores devem ter maior disponibilidade de microhabitats usti cando a tendência observada. Os resultados obtidos indicaram que as dimensões das raízes E. azurea podem desempenhar importante papel ecológico como abrigo e local de acúmulo de alimentos para os macroinvertebrados em lagoas.

Macrophytes play an important role in the community structure of aquatic systems. In this study, we examined the macroinvertebrate communities within 20 Eichhornia azurea roots in an oxbow lake in Pantanal (MS) during dry season. Species abundance and richness were compared via linear regression, and the mean relative proportion of macroinvertebrates among root samples was determined. Macroinvertebrates were identi ed to the lowest practical taxonomic level, and root volume was measured using the volume displacement method. We identi ed 3 1 specimens, belonging to 31 families and 21 taxonomic groups. Chironomus sp.

“…The rate of development of chironomid larvae generally increases with increasing ambient temperatures (e.g. Mackey 1977, Pinder 1986). Differences in winter/ spring temperatures and differences in the warming up rate of the larval habitat might thus explain observed differences in timing of emergence of the wintering populations between years and between habitats.…”

The life-history and behaviour of the chironomid Metriocnemus (Inermipupa) carmencitabertarum was studied for three years and a comparison was made between two populations in the Netherlands. Key life-history characteristics are reported, including the number of generations (2-5 generations) and duration of larval development (19-55 days). Life-history characteristics differed between the two populations and between generations within a population. These differences were likely related to differences in competitors (mainly Chironomus riparius Meigen) and thermal characteristics of the habitat from variations in water volume and ambient temperature. Results suggested a diapause in summer, when water levels dropped, and not in winter. A clear seasonal pattern in body size was found with pupal length increasing steeply at the beginning of the summer. The increase in body size was positively correlated with mean ambient temperature during larval development. This correlation is in contrast with the TemperatureSize Rule (TSR) in ectotherms, which postulates a negative correlation between temperature and adult body size. The chance of ectotherm predators being present in the habitat is low, which may explain this feature. Life history characteristics supported a recent northward range expansion for M. (I.) carmencitabertarum due to warmer winters. If correct, it is predicted that the species will be found in Scotland and northern Germany and/or southern Denmark in the near future.
