Historical Perspective On Ecosystem Engineering
Natalie Buchman, Kim Cuddington, and John Lambrinos Ecologists have been aware that animals and plants modify the physical environment for at least 150 years, even though the term ecosystem engineer was not coined until 1994 (Jones et al. 1994). As we have argued elsewhere (Beisner and Cuddington 2005), awareness of the historical development of any ecological topic can lead to deeper understanding and more rapid scientific progress. In this spirit, we outline some of the major areas of...

Sphaeroma Quoianum
S. quoianum ( S. quoyanum, S. pentodon) lives intertidally (Riegel 1959, Morris et al. 1980) and burrows into a variety of available soft substrates including peat, mud, and soft rock. It also bores into floating material FIGURE 9.1 Schematic diagrams showing the conversion of a (A) salt marsh, (B) mangrove, and (C) kelp forest to open, unvegetated systems initiated by the burrowing activities of isopods. The burrows of the isopods also create fine-scale habitat for bur-rowing-dwelling...

Plant-feeding insects that construct shelters on their food plants provide ample opportunities for examining the impacts of allogenic ecosystem engineering on nature's most diverse group of organisms, the arthropods. Shelters serve as habitats for a variety of plant-dwelling arthropods that exploit a range of available resources within these constructs. The small size and somewhat ephemeral nature of these constructs at first may suggest their effects on animal community composition and...
Posteradication Flora And Fauna Dynamics
TNC recognized that there were many potential outcomes of the sheep eradication program (Schuyler 1993). The fundamental and most desirable one was that native biodiversity would be maintained or improved, but they were also aware that other outcomes could be undesirable or have unknown consequences. These included an increase in the pig population because of increased food and cover, increased fire frequency and extent resulting from increased vegetation biomass, and an increase in non-native...
