“…Allan 1936, Egler 1942, Elton 1958, and it appears that many invaders are more successful on more fertile soils (Gerrish andMueller-Dombois 1980, Bridgewater andBackshall 1981). Invasions of all kinds are more often successful on oceanic islands then continents (Elton 1958), and this is Ecosystem Management: Selected Readings true of invasion into parks and preserves as well as disturbed areas (Loope and MuellerDombois, in press).…”

“…Prior to mangrove introduction, Hawaii essentially lacked marine vascular plants (Wester 1981), despite the availability of suitable habitats (Egler 1942). Vascular plants can alter wetland habitat characteristics and faunal community structure through a variety of direct and indirect mechanisms, acting as major ecosystem engineers (Orth 1977, Orth et al 1991, Jones et al 1997, Crooks 2002.…”

Mangroves were introduced to the Hawaiian Islands in 1902, providing an unusual opportunity to examine the impacts of introduced vascular plants on coastal ecosystems. Despite >100 yr residence in Hawaii, little is known regarding how mangroves alter coastal ecosystem structure. We conducted a case study of 2 Rhizophora mangle habitats in Hawaii, comparing habitat parameters and macrofaunal community structure in introduced mangroves and nearby control sandflats at a similar tidal elevation. Mangrove sediments had finer sediments and higher organic carbon concentrations and porewater salinities than sandflats. Emergent mangrove roots were colonized by the introduced barnacles Chthamalus proteus, Balanus reticulatus, and B. amphitrite and the introduced sponges Suberites zeteki, Sigmadocia caerulea, and Gelloides fibrosa. Higher densities of non-native macrofauna were found in mangrove transects than in sandflat controls, indicating that invasive mangroves facilitate the persistence of non-native fauna in Hawaii. Mangrove habitats also had higher macrofaunal species richness and diversity, as well as greater dominance by subsurface deposit feeders. Introduced mangroves substantially altered benthic community structure, in part by enhancing the structural complexity of the Hawaiian coastal environment. Because macrobenthos provide a variety of ecosystem services, e.g. serving as prey for fish and birds and promoting detrital decomposition, mangrove-induced changes in sediment community composition will likely have farreaching consequences in Hawaii. Similar consequences of mangrove invasion are likely in other regions, as mangrove habitats expand with climate warming and increased coastal sedimentation.

Prior to mangrove introduction, Hawaii essentially lacked marine vascular plants (Wester 1981), despite the availability of suitable habitats (Egler 1942). Vascular plants can alter wetland habitat characteristics and faunal community structure through a variety of direct and indirect mechanisms, acting as major ecosystem engineers (Orth 1977, Orth et al. 1991, Jones et al. 1997, Crooks 2002. Introduced Rhizophora mangle is likely to act as a major ecosystem engineer in the Hawaiian intertidal, causing increased availability of hard substrata for encrusting organisms, higher porewater salinities, and reduced light levels and rates of water flow (e.g. Alongi 1987a, Shokita et al. 1989, Levin & Talley 2000, Whitcraft & Levin 2007. By reducing water flow, the root structure traps fine and organic-rich sediments transported by currents or produced in situ from mangrove litter (Chapman...

“…He also has precursors outside of invasion biology, for instance in ecology (Egler 1942 ) and in various branches of philosophy. And as in the case of Mark Sagoff, many of his criticisms and suggestions resonate with ideas currently expressed in invasion biology (see, for example, Reise et al 2006 ;Davis 2006Davis , 2009 ).…”
