Interactions between bacteria and phytoplankton in the phycosphere have impacts at scale of whole ecosystems, including development harmful algal blooms. The cyanobacterium Microcystis causes toxic blooms that threaten freshwater ecosystems human health globally. grows colonies harbour dense assemblages other bacteria, yet taxonomic composition these communities nature their interactions with are not well characterized. To identify taxa compositional variance within communities, we performed...
Cyanobacterial harmful algal blooms (cyanoHABs) degrade freshwater ecosystems globally. Microcystis aeruginosa often dominates cyanoHABs and produces microcystin (MC), a class of hepatotoxins that poses threats to human animal health. Microcystin toxicity is influenced by distinct structural elements across diversity related molecules encoded variant
In the oligotrophic oceans, key autotrophs depend on "helper" bacteria to reduce oxidative stress from hydrogen peroxide (H2O2) in extracellular environment. H2O2 is also a ubiquitous stressor freshwaters, but effects of and their interactions with are less well understood freshwaters. Naturally occurring freshwater systems proposed impact proportion microcystin-producing (toxic) non-microcystin-producing (nontoxic) Microcystis blooms, which influences toxin concentrations human health...
Interactions between bacteria and phytoplankton can influence primary production, community composition, algal bloom development. However, these interactions are poorly described for many consortia, particularly freshwater bloom-forming cyanobacteria. Here, we assessed the gene content expression of two uncultivated Acidobacteria from Lake Erie Microcystis blooms. These organisms were targeted because they previously identified as important catalase producers in blooms, suggesting that...
Pitfall traps were used to sample the terrestrial ant and beetle fauna of four large State Forests five roadside strips white cypress pine woodland in wheat belt central western New South Wales. In total, 93 morphospecies 82 identified. The species richness total abundance both ants beetles did not differ significantly between Forests. Multivariate analyses detected significant differences community composition faunas vegetation. Differences similar regardless whether analysis was conducted...
Differences in the assemblages of terrestrial arthropod communities burnt and adjacent unburnt areas coastal heathland are reported. The site experienced a wildfire 20 months prior to sampling. Collections invertebrates from pitfall traps winter indicated that there was no difference total species richness or numbers individuals trapped between plots. However, at level, 60 percent taxa showed strong preference for either with only few around equal both areas. Twenty were found on...
The ant genus Leptomyrmex contains 41 named taxa which are limited to eastern Australia, New Guinea and Caledonia. While most species large distinctive, a few much smaller have only recently been recognised as belonging this genus. These six species, informally called micro-Leptomyrmex, restricted rainforests wet sclerophyll forests in two relatively small regions of Australia. All described here for the first time include L. aitchisoni n. sp., burwelli dolichoscapus garretti pilosus sp. ramorniensis
