... Mouthparts of adult Tanyderidae are examined in detail for the first time, with emphasis on scanning electron microscopy. A full set of mouthparts, devoid of conspicuous dentation or serration and showing no differences between sexes, was found in both examined species, Eutanyderus wilsoni Alexander, 1928 and Peringueyomyina barnardi Alexander, 1921. The mouthparts are elongated into a proboscis i ...

Abstract:
... The analysis of the water distribution network is complicated and requires several assumptions to simplify its problem definition. Demand Driven Analysis (DDA) is typically used to analyse the network assuming that all network nodes can deliver the required demand regardless of the available pressure. In the case of analysing an existing network under deficit condition such as pipe breakage or ext ...

Abstract:
... During deposit feeding on benthic micro-algae, the siphon of buried tellinid bivalves like Macoma balthica is vulnerable to nipping by plaice Pleuronectes platessa and other flatfish. We experimentally tested the hypothesis that siphon nippers facilitate predation on the entire bivalve (by shorebirds, for example) by inducing a decrease in burying depth. Three experiments in May and in September, ...
