“…Being light-weight, small in size (Hester-Dendy samplers) and suspended in the water column means that mid-water samplers are less stable than benthic samplers (Minshall 1984). Stability of the substrate plays an important role in the distribution of macroinvertebrates (Luedtke & Brusven 1976, Malmqvist et al 1978, with at least an intermediate degree of stability needed to support a more abundant and diverse community (Stanford & Ward 1983). In addition, macroinvertebrates in lentic environments tend to be closely associated with the benthos (Merritt & Cummins 1996).…”

Reliable quantitative methods for sampling invertebrate communities are critical for effective freshwater biomonitoring. We tested a range of devices and protocols for sampling benthic macroinvertebrates in shallow tropical lakes; this is the first time this has been attempted in Southeast Asia. First, a pilot study to identify a suitable artificial substrate and colonisation period was conducted. Coconut brushes combined with split palm fronds attracted the greatest macroinvertebrate abundance and richness. A colonisation period of 4 wk was sufficient to capture the key macroinvertebrate families and orders. Second, the sampling efficiencies of 7 artificial substrate sampler designs and 2 hydraulic suction devices were compared in rocky and soft-sediment littoral habitats of a reservoir in Singapore. Among the 9 different sampling techniques tested, the samplers containing coconut brushes and split palm fronds again were the most effective at capturing the greatest total abundance and family richness of benthic macroinvertebrates. Variation in community structure among sampler types was largely explained by the abundance of Chironomidae and Polymitarcyidae (Ephemeroptera). Results were similar between sites dominated by 'rocky' and 'vegetated' littoral habitats. This project identified a sampling device suitable for biomonitoring Singapore's lentic environment, with protocols likely to apply to shallow tropical lentic systems elsewhere.

“…In fact, due to their stable ecological features and their interface with freshwater and groundwater systems, they can support a variety of relatively rare and unusual fauna (Glazier 1991;Di Sabatino et al 2003), providing refuge from disturbance events or extreme seasonal conditions. Furthermore, they may act as a source of downstream colonizers and a permeable ecotone for the interaction of phreatic and surface communities (Stanford & Ward 1983).…”

“…The influence of seasonal variation of water temperature on macrozoobenthos diversity has been most thoroughly investigated in eurythermal streams (Vinson & Hawkins, 1998). It has been established that an increase in temperature variations, mainly down a gradient of elevations above sea level, results in an increase of diversity (Ward & Dufford, 1979;Stanford & Ward, 1983;Lillehammer, 1985;Ward, 1986), although there are contrary findings (Resh, 1983).…”

In contrast to cold and eurythermal waters, benthic communities of warm brooks in temperate regions have been inadequately studied. In order to investigate the effects of water thermal regime on the benthic communities of warm waters and their relationships with those of cold and eurythermic ones, the macrozoobenthos was studied at eight sites in the Toplica River, and at four sites in its tributary, the Termalni brook. Investigations were carried out seasonally from April 2000 to January 2001. Warm waters of the Termalni brook were characterized by specific macrozoobenthos assemblages that exhibited significant differences to the populations of eurythermal and cold waters of the Toplica River. The dominant taxa in the macrozoobenthos community of warm waters were mainly Gastropoda species. Moreover, benthic communities of warm waters were characterized by lower diversity and greater biomass in comparison with those of cold and eurythermal waters. The gradient of average annual temperatures represented the main ecological factor influencing changes of diversity and biomass along the course of the investigated Termalni brook. Inflow of warm waters at site T6 lead to a decrease in macrozoobenthos abundance and changes in qualitative and quantitative composition of the benthocoenosis of a highland stream, but did not significantly alter diversity.
