“…i) the fauna of Yuccabine Creek was recovering in 1983 from a prolonged dry spell; ii) unrecorded spates between sampling dates; iii) seasonal life cycles; and iv) the known patchy distribution of the benthic fauna resulting in high variance in population estimates (Pearson et al, 1986).…”

Drift and upstream movement were monitored over 14 months in a seasonal upland tropical stream in northeastern Australia. There were distinct seasonal pulses in the drift with variable peak levels in the summer wet season and low more stable levels during the dry season. Drift density ranged from 0.36 to 3.98 animals per m3 (monthly mean = 1.26). There was no correlation between drift density ad either benthic density or stream discharge. In the absence of catastrophic drift, drift was dispersive, not depletive in the wet season. A total of 121 taxa were caught in the 14 drift samples. Most taxa had nocturnal maximum drift levels with a peak immediately aftei sunset, a pattern apparently related to level of light and not temperature. Compensation for drift by upstream-moving nymphs and larvae was least during the wet season and increased during the dry season to a peak of 27% by numbers. Mean compensation was 8.2%. It is suggested that apart from in the wet season when an animal may drift substantial distances, most riffle animals will spend their larval lives in one small stretch of stream.

“…Riparian vegetation is primarily mesophyll vine forest with some tall closed mixed forest (sensu Webb, 1959) which forms a closed canopy over the sampling site. The water from Yuccabine Creek is slightly acidic (pH 5.9-6.9) and has low conductivity (33-70 $S cm-') (Pearson et al, 1986).…”

“…Comparisons among detailed studies suggest that diversity in the tropics is greater (e.g. Bishop, 1973;Pearson et al, 1986;Smith and Pearson, 1987;Table II) or lower (Arthington, 1990) but are hindered by lack of standardization of methods used.…”

“…Further support for this approach can be drawn ftom the fact that the end-points (Tasmania and North America) have well-described faunas whereas two regions with negative residuals (Queensland and tropical South America) have incompletely described faunas (Christidis, 2003). It is probable that the pattern would vary somewhat among different taxa; for example, Trichoptera and Diptera are particularly diverse in Australia (Pearson et at., 1986;Lake et aI., 1994). Using the same approach, Odonata yield a similar trend to Ephemeroptera with tropical regions showing positive deviations from the regression line whereas the negative deviations are represented by temperate data sets (Fig.…”

“…Thus, Pearson & Smith (1986) in a careful study of the diversity and abundance of the macroinvertebrates of Yuccabine Creek, a tropical rainforest stream in north-eastern Queensland, found that the total number of macroinvertebrate taxa from one site was high compared to temperate streams in Australia (and even when compared to tropical streams outside Australia). The mean number of species found by them per sample was 105 (with a range 85-134), and the total number of species recorded from a single 50 m stretch of riffle was 267.…”

Species richness in tropical fresh waters of Australia

General ecological expectations about the relationship between latitude and species richness are that at low latitudes (the tropics) species richness is greater than at higher latitudes (temperate and polar regions). Recent work suggests that this may not be the case for several habitat types and biological groups in Australia. Results are conflicting: on present evidence (admittedly sparse) it appears that in Australian tropical fresh waters species richness is generally depressed in zooplankton and littoral microfaunal communities, but not in macroinvertebrate communities in typical streams and in fish communities (and perhaps also in amphibian and reptile communities).The situation is indeterminate for tropical phytoplankton and macrophyte communities.
