Last Tuesday, police cleared a small patch of the occupied area in Mong Kok, though there were more reporters and spectators than actual protesters.
Model predictions were made for the total number of animals, the distribution of animal density among patches, the total number of occupied patches, and the probability of patch occupancy.
As the fraction of occupied patches increased, patches were colonized and abandoned at earlier ages.
Overall, the aphid was restricted to those patches at phenological stages 2, 4 and 5. Just 8% of D. octopetala patches at stage 2 were occupied by the aphid but the percentage of occupied patches increased to 35%and6767% for stages 4 and 5 respectively (Table 1).
The landscape scale described habitats within a 1-km radius of occupied patches and an equivalent sample of vacant patches.
While some of the models gave reasonable forecasts of the number of occupied patches, even in these cases, they had only moderate ability to predict which patches were occupied.
Predictions of patch occupancy were not significantly different from the actual value for the number of occupied patches in half the models tested.
Some of the models gave reasonable predictions for the number of occupied patches, but those models were unable to predict which ones were actually occupied.
Five of the 18 scenarios completed for the Agile Antechinus gave predicted numbers of occupied patches not significantly different from the observed number.
The mean detection probabilities of water vole signs in autumn (0.71) and winter (0.81) indicated that false absences may be generated in about 20 30% of occupied patches surveyed by a single observer on a single occasion.
