    • ... However, although some studies of contemporary gene flow in fragmented landscapes have found that habitat fragmentation can promote long-distance pollen gene flow (...

    • ...Recent work has shown that pollinator communities, abundance and behaviour may change in fragmented habitats promoting long-distance pollen flow (Aldrich and Hamrick 1998; Dick 2001; White et al. 2002)...
    • ...Trees in isolated pastures may sire a large proportion of seeds in continuous or remnant populations and have the potential to link fragments separated by large distances, therefore effort should be devoted to identify and preserve such isolated individuals (Aldrich and Hamrick 1998)...

    • ...Colonisation of cleared areas also has the potential to introduce a genetic bottleneck in the demographic cycle of pioneer species due to limited propagule sourcing (Dlugosch and Parker 2007 ;L owe et al.2005), and the few studies of tropical trees from secondary forest confirm this expectation (Symphonia globulifera, Aldrich and Hamrick 1998; Swietenia macrophylla ,C espedes et al. 2003; Elaeocarpus grandis, Rossetto et al. 2004)...

    • ...The reduced genetic diversity in small, isolated populations (e.g., Jump and Pen ˜uelas 2006; Van Rossum 2008) can paradoxically be most pronounced in those with the highest levels of recruitment (e.g., Van Rossum 2008) such as when relatively few nearby parents dominate recruitment (Aldrich and Hamrick 1998)...

    • ...However, forest fragmentation may breakdown this pattern of nearest neighbor mating, as has been found in isolated trees and populations occurring in highly fragmented landscapes, including of Symphonia globulifera (Aldrich and Hamrick 1998), Swietenia macrophylla (White et al. 2002) and Dinizia excelsa (Dick et al. 2003)...
