Cuticular Layer

Rheophytes are restricted to stream beds that are regularly flooded by swift-running water after rains and are morphologically characterized by having narrow, (ob)lanceolate leaves – leaflets (stenophylls) and other features that are adapted to the unique habitat, decreasing resistance to the swift-running water. The present study characterized anatomically the leaves of fern rheophytes. Generally, the mesophyll cells of rheophytes are less expanded, and therefore their intercellular spaces are smaller than those of related dryland species. Furthermore, frequency of occurrence of stomata per unit leaf area is greater, the cuticular layer is thicker, and the epicuticular wax deposits on the leaf epidermis are denser in at least some rheophytes than in related dryland species. It can be assumed that the stenophylls of the rheophytes are produced by developmental events, including weaker cell expansion than in dryland species, and that a phylogenetic decrease in cell expansion in leaves was involved in the origin of stenophylls from broader leaves of ancestral dryland species. The leaf anatomical features are discussed in relation to the ecological specificity of the rheophytes. Key words: evolution, flood resistance, intercellular space, leaf anatomy, rheophytic ferns, stenophyll.

Recovery Experiences

The 2010 floods in Pakistan had a devastating effect on the Pakistani population. This paper summarises recovery experiences from previous natural disasters in South Asia, including the 2005 earthquake in Pakistan and the 1998 flood in Bangladesh, and suggests several lessons relevant for recovery efforts following the 2010 Pakistan flood. First, market and trade policies should maintain adequate price incentives so that private trade and imports can contribute to postdisaster recovery. Second, a strong institutional framework is needed to coordinate the large-scale disaster response. Third, recovery efforts should also include support for livelihood security and restoration, ensuring inclusion of the stakeholders. Fourth, restoring and upgrading infrastructure facilities can lead to enhanced flood resistance as well as a reduction in future disaster loss. Two alternative institutions may be possible vehicles for poverty-alleviation—the Pakistan Poverty Alleviation Fund (PPAF) and the Benazir Income Support Programme (BISP). To address future disasters, however, it is important to establish and strengthen disaster response capability, including applying lessons learned from the relief and rehabilitation response to the 2010 floods.

The responses of seedlings of Tristaniopsis laurina and Acmena smithii, two important tree species in riparian warm temperate rainforest communities in Victoria, are investigated in relation to flood disturbances. Freshly germinated A. smithii seedlings had died within 5 weeks of complete waterlogging in the greenhouse, and although the young T. laurina seedlings survived waterlogging for 14 weeks, their growth rate was curtailed. Nine-month-old seedlings of both species were found to be relatively tolerant to waterlogging, forming aerenchymatous surface roots after 40 days of flooding. Neither species suffered leaf abscission or demonstrated any other signs of water stress commonly associated with flood intolerant species. In experiments to determine the resilience of these species to physical flood damage, both species also demonstrated a capacity to regenerate vegetatively following the removal of above ground parts in young seedlings. The heartwood of T. laurina was found to be more decay resistant than that of other species in the field including that of A. smithii. The significance of these results are discussed in relation to other factors examined in earlier papers adding to the understanding of the ecological status of these species within the riparian rainforest communities.
