Variation in relative abundance of major or indicator taxa and taxon groups in relation to a dry land pollen sum for selected pollen records from north-eastern Australia (Lynch’s Crater and ODP Site 820) compared with charcoal values for each site expressed as particles/cm 3, the planktonic δ 18O curve from ODP Site 820, and the marine isotope stratigraphy of Martinson et al. For example, in Central America, TMS streams flowing over Pleistocene glacial deposits can be a few kilometers away from streams draining highly weathered oxisols and carbonate platforms.įigure 6.

They also tend to drain spatially diverse and complex geology before they enter the lowlands and coastal plain. As described in detail later, the TMSs considered here are located in forested montane areas below the alpine tree line and in areas that have cooler temperatures and higher rainfall than adjacent lowland regions.

Nevertheless, identifying TMSs can be just as challenging and as conceptually useful as defining large rivers ( Potter, 1978 Miall, 2006). Figure 1 contains a generalized map of their occurrence that was developed from our knowledge of their distribution and by identifying ecoregions of tropical and subtropical humid montane forests ( Olson et al., 2001). This chapter is focused on streams in mountainous regions of the humid tropics that currently receive 2000–3000 mm or more of precipitation each year.
