Virus-like particles associated with Lyngbya majuscula (Cyanophyta; Oscillatoriacea) bloom decline in Moreton Bay, Australia

Analyzing variability and the rate of decline of migratory shorebirds in Moreton Bay, Australia.

Estimating the abundance of migratory species is difficult because sources of variability differ substantially among species and populations. Recently developed state-space models address this variability issue by directly modeling both environmental and measurement error, although their efficacy in detecting declines is relatively untested for empirical data. We applied state-space modeling, g...

Integrating Science through Bayesian Belief Networks: Case study of Lyngbya in Moreton Bay

Bayesian Belief Networks (BBNs) are emerging as valuable tools for investigating complex ecological problems. In a BBN, the important variables in a problem are identified and causal relationships are represented graphically. Underpinning this is the probabilistic framework in which variables can take on a finite range of mutually exclusive states. Associated with each variable is a conditional...

Wewakamide A and guineamide G, cyclic depsipeptides from the marine cyanobacteria Lyngbya semiplena and Lyngbya majuscula.

Two new cyclic depsipeptides wewakamide A (1) and guineamide G (2) have been isolated from the marine cyanobacterium Lyngbya semiplena and Lyngbya majuscula, respectively, collected from Papua New Guinea. The amino and hydroxy acid partial structures of wewakamide A and guineamide G were elucidated through extensive spectroscopic techniques, including HR-FABMS, 1D (1)H and (13)C NMR, as well as...

Exploring Cultural Constructs: the Case of Sea Mullet Management in Moreton Bay, South East Queensland, Australia

Incorporating indigenous knowledge into fisheries management is becoming increasingly important in the derivation of alternative management solutions. It also satisfies the political demands of indigenous communities to exercise their rights and responsibilities to traditional resources and their management. Using a methodology that considers perceptions or constructs of the environment to be d...
