    Three new Neotropical species of aquatic non-biting midges, Nilothauma canaima n. sp. from the Bolívar State, Venezuela, N. granma n. sp. from Granma Province, Cuba, and N. soka n. sp. from the Amazon State, Brazil are described and figured, and a key to the males of Nilothauma from the New World is given.

  • Mar Chiquita is a large salt lake of international importance because of its biodiversity. Key findings include its eutrophic condition and occurrence of a marked spring nutrient turnover followed by a clear water summer, despite lack of thermal stratification. Instead, lake shallowness and the subtropical climate appear as the main driving factors.

  • Photosynthetic performances of epilithic freshwater lichens representative of various submersion conditions were compared. Pigment composition, respiration rate, photosynthesis activity and PSII efficiency after thalli hydration/dehydration were determined, emphasizing large differences in photosynthetic traits of hyper- and sub-hydrophilic lichens. Our results reveal that performances of different freshwater lichen taxa are consistent with their habitat characteristics.

  • The effect of predatory insects on prey size distribution was investigated in two temporary Andean wetlands, located in northwest of Patagonia Argentina. The wetlands studied showed heterogeneous prey size structure and the insects impacted on survival of different prey size and stages. However the size-limited predators investigated here, seems no influence on the body size structure of the prey, other variables could be more important in the size structure of these aquatic ecosystems.

  • Recent threat of habitat loss and fragmentation impels us better understanding how habitat specific dynamics influence overall ecosystem processes. This paper demonstrates that each habitat type should be considered as a discrete metabolic entity and that particular sets of environmental factors are responsible for habitat specific metabolic responses. Such findings have a great applicability in river restoration initiatives, particularly when benthic metabolism is used as indicator of ecosystem function.
