Spatiotemporal Indexing With the M-Tree
… spatiotemporal data in real time. Because the M-Tree has been proven as an index for spatial network databases, we have selected it to be enhanced as a spatiotemporal index. We present modifications to the tree which allow trajectory reconstruction with fast insert performance and modifications …

Improving Performance of Spatial Network Queries
… between network points are stored in an M-Tree index, a balanced tree index where metric distance determines data ordering. The M-Tree uses the chessboard metric on network points embedded in a higher dimensional space using tRNE. Using the M-Tree both KNN and range queries are computed …

A Comparison of Eastern Gray Squirrel (Sciurus Carolinensis) Nesting Behavior among Habitats Differing in Anthropogenic Disturbance
… disturbance. Among the habitats, food trees were preferred over non-food trees. Nests were built at a height of approximately 12 m. Tree size preferences tended toward those at least 10 cm in diameter. Trees used in developed areas were larger than trees in natural areas, due to …

Revealing the behavioural ecology of the elusive hairy-eared dwarf lemur (Allocebus trichotis)
… diet or the use of patchily distributed gum-trees. Each focal animal used four or five different tree holes and shared these with conspecifics and occasionally with white-tailed tree rats (Brachytarsomys albicauda). Tree holes were in living trees with average diameters at breast height of 32 …

Nocturnal roost tree, roost site and landscape characteristics of Carnaby's Black-Cockatoo (Calyptorynchus latirostris) on the Swan Coastal Plain
… A minimum of five and maximum of ten individual trees were assessed at 11 roost sites with an overall total of 95 roost trees sampled. I determined the tree species composition and vegetation structural arrangement, as well as the roost site location properties of each of the selected roosts. A …
