“…Moreover, it is worth to mention the absence of fishes thus allowing the highest production of Simuliidae and Hydropsychidae larvae, which can be mainly used by Megaloptera larvae. Macro-filtering collectors (Smicridea and Leptonema, Hydropsychidae) are known to be very productive when the invertebrate drift densities are high (Benke, 1993) an almost permanent situation at this ecosystem. In February, the Hydropsichidae larvae were mainly the big ones in the last instar, while the simuliid larvae were small, a situation just the opposite recorded in April.…”

Biodiversity assessment of benthic macroinvertebrates in altitudinal lotic ecosystems of Serra do Cipó (MG, Brazil)

Five lotic systems of Serra do Cipó, south-east Brazil, were investigated in order to assess the existing diversity of benthic macroinvertebrates, habitats-microhabitats, and the available trophic resources. For each river it was analysed the communities of benthic macroinvertebrates and the composition of some taxonomic groups (Plecoptera, Ephemeroptera, Trichoptera and Diptera Chironomidae): the community with Bivalvia Sphaeriidae, Oligochaeta and Ephemeroptera Baetidae (being supposed a closed relation Bivalvia-Oligochaeta based on the process of bioturbation and enrichment of sediment in organic matter) in Tanque River; the macrofauna associated to aquatic macrophytes from rivers Peixe and Preto do Itambé reflecting the reaction of the ecosystems versus the quantities of nutrients which originate from the farmlands; the lithoreophilic communities of Cipó River; the community depending on deposits of leaves and filamentous algae in Congonhas Stream; the very rich community of the moss clumps in the Indaiá Stream. A proposal for biological zonation of Cipó River and some comments about the importance of the analysed benthic macroinvertebrates in the biological production of the aquatic communities were done.

“…A total of 14,878 atyid shrimps specimens were sampled, preserved in formalin 4%, measured for carapace length [24,25] using ocular micrometer, weighted with Sartorius balance of 0.01 g of precision and identified using keys of De Man [26], Monod [27] and Day et al [28]. Atyid production and biomass turnover were estimated by size frequency method according to sites [15,21,[29][30][31].…”

“…The analysis of Table 2 shows that the P/B ratios observed are located in the interval of 3 year -1 to 9 year -1 for the shrimps which are univoltine species [15]. Concerning the variation of P/B ratios, sometimes enormous, within a same species, Benke [36] thinks that it is bound to the particular environmental conditions to which is submitted a population, notably the types of habitats, the climate and other factors that act on and regulate the population.…”

“…The majority of studies concerning the production of the benthic invertebrates of freshwaters has especially been centered on the Insects. Only less than 5% of the evaluations of production inventoried by Benke [15] concerned the Crustaceans. Of these, more than 90% were dedicated to the Amphipods and Isopods that are supplanted by the Decapods in the tropical rivers.…”

Decapod crustaceans are one of the dominant faunal components of most tropical streams. However, several aspects concerning their biology and ecology are poorly known, especially in intertropical Africa. The aim of this study was to investigate the production of the atyid shrimps in Masanga Mabe, an equatorial lowland forest stream of Kisangani region. Samplings were undertaken biweekly from September 2000 to August 2003 with Surber net in four study sites. A total of 14,878 atyid shrimps specimens were sampled, measured for carapace length, weighted and identified. Atyid production was estimated by size frequency method according to sites (1, 2 and 3). Atyid composition showed the existence of two species: C. africana (Caridina africana) Kingsley 1882 and C. togoensis (Caridina togoensis) Hilgendorf 1893. Specific production ranged from 1.35 g·DM·m

“…Natality, abundance, individual growth rate, individual biomass, dispersal, and survival are all important life-history attributes that together determine levels of production at the population level (Benke 1984(Benke , 1993. Aquatic insects are important in energy flow in freshwater ecosystems, since they constitute an important link between the algal/detrital food base and the higher trophic levels, including fishes (Benke 1984).…”

In this study we focused on life history parameters of Electrogena ujhelyii. We studied life cycle, nymphal growth pattern, biomass and secondary production in a small, calcareous stream in Malé Karpaty Mts (West Carpathians). The life cycle was univoltine with a large range in the size of nymphs during most samples dates. Mean annual density was 40 ind. m −2 and the annual secondary production reached 183 mg DW m −2 y −1 . There are no published data available on the secondary production values of this species, therefore these are the first published data.
