There is also evidence that the larvae of some crabs and fishes in temperate waters use acoustic cues from urchin-dominated reefs to detect and locate settlement sites (see [4]).
To test this concept, one strategically located settlement was chosen: Deir 'Alla.
In many coral reef fish, olfaction plays a critical role in locating settlement habitat following a larval dispersal stage (Atema et al., 2002; Lecchini et al., 2005; Gerlach et al., 2007; Leis et al., 2011).
This expansion may have influenced the settlement patterns of both cultural complexes, leading populations to locate their settlements principally within landscape units that remained clear of extensive fir forests.
Archaeological survey often employs aerial photographs and satellite images to locate human settlements and related features visible on the surface.
As a result, a characteristic of a colonizing population might be that it will very clearly demonstrate a preference for gross habitat types, and within these gross habitat types they might locate their settlements in very similar places.
While exact mechanisms that enable A. percula larvae to locate suitable settlement sites are unknown, Dixson et al. suggest that an olfactory response to chemical cues of island vegetation may play a role (Dixson et al., 2008).
Most of the suitable areas from Fig. 6 were located behind settlements.
The sandy ramata landscapes, which tend to form piles of soil due to soil movements, are also avoided when it comes to locating pastoral settlements.
Large-scale studies of Brazilian agrarian reform suggest that locating smallholder settlements near urban centers rather than in isolated frontier regions can facilitate not only improved environmental performance, but also farmer incomes and standards of living that are higher than the regional average.
The hypothesis is that settlements traditionally locate on places where the more fertile and intensively used grounds can easily be controlled.
