Creating large conservation zones in remote areas, with less intense stakeholder overlap and limited environmental information, requires periodic review to ensure zonation mitigates primary threats and fill gaps in representation, while achieving conservation targets. Follow-up reviews can utilise improved methods and data, potentially identifying new… (More)
Selecting reserve areas based on percentages, such as 10% or 12% of a bioregion, is common in conservation planning despite widespread admission that such percentages are arbitrary and likely to be inadequate for the conservation of all biodiversity.

Zonae Cogito is a free software package that couples Marxan with a MapWindow GIS interface to provide practitioners with an easy to use GIS to support Marxan analysis. In addition to providing a method for visualizing Marxan output, Zonae Cogito extends the basic Marxan functionality to better support an iterative and interactive design process. Zonae… (More)
In the burrowing cockroach Arenivaga, two giant interneurons in each connective of the ventral nerve cord provide gravity orientation information. The interneurons receive input from plumb bob-like equilibrium receptors on the ventral surface of the cerci. Ouir results support the theory that the cerci of cockroaches are specialized equilibrium organs.
