Book Description
We conceived the idea for this book after teaching a graduate seminar on 'Habitat Complexity' at The University of South Florida. Discussions during the seminar led us to conclude that similar goals were to be found in studies of the topic that spanned the breadth of ecological research. Yet, the exact meaning of 'habitat structure', and the way in which it was measured, seemed to differ widely among subdisciplines. Our own research, which involves several sorts of ecology, convinced us that the differences among subdisciplines were indeed real ones, and that they did inhibit communica tion. We decided that interchange of ideas among researchers working in marine ecology, plant-animal interactions, physiological ecology, and other more-or-less independent fields would be worthwhile, in that it might lead to useful generalizations about 'habitat structure'. To foster this interchange of ideas. we organized a symposium to attract researchers working with a wide variety of organisms living in many habitats, but united in their interest in the topic of 'habitat structure'. The symposium was held at The University of South Florida's Chinsegut Hill Conference Center, in May. 1988. We asked participants to think about 'habitat structure' in new ways; to synthesize important, but fragmented, information; and. perhaps. to consider ways of translating ideas across systems. The chapters contained in this book reflect the participants' attempts to do so. The book is divided into four parts, by major themes that we have found useful categorizations.

Book Description
Estuarine Perspectives presents most of the invited papers presented at the Fifth Biennial International Research Conference on Estuarine Research. The book includes information on one tropical and two Arctic estuaries; contemporary techniques as applied to estuarine research; and some hypotheses of estuarine ecology. The text also describes value and management of wetlands as well as the chemical cycles and fluxes. The primary production and photosynthesis; the physical and biological factors of estuarine sediment; and the ecosystem dynamics are also encompassed.

Book Description
Structurally complex habitats support high species diversity and promote ecosystem health and stability, however anthropogenic activity is causing natural forms of complexity to rapidly diminish. At the population level, reductions in complexity negatively affect densities of territorial species, as increased visual distance increases the territory size of individuals. Individual behaviour, including aggression, activity and boldness, is also altered by complexity, due to plastic behavioural responses to complexity, habitat selection by particular personality types, or both processes occurring simultaneously. This thesis explores the behavioural effects of habitat complexity in four chapters. The first chapter, a laboratory experiment based on the ideal free distribution, observes how convict cichlids (Amatitlania nigrofasciata) trade-off the higher foraging success obtainable in open habitats with the greater safety provided in complex habitats under overt predation threat. Dominants always preferred the complex habitat, forming ideal despotic distributions, while subordinates altered their habitat use in response to predation. The second chapter also employs the ideal free distribution to assess how convict cichlids within a dominance hierarchy trade-off between food monopolization and safety in the absence of a predator. Dominants again formed ideal despotic distributions in the complex habitat, while dominants with lower energetic states more strongly preferred the complex habitat. For both laboratory experiments, personality did not predict habitat preference. The third chapter, a field study with juvenile Atlantic salmon (Salmo salar), tested whether stream restorations that increase habitat complexity will also select for particular personality traits, and we again found that complexity did not favour any particular personality types. A broader range perspective regarding the effects of habitat complexity on behaviour was addressed in the fourth chapter via a meta-analysis on a wide range of territorial and non-territorial taxa. Territoriality modified the effects of complexity on behaviour, likely due to the strong reliance of territorial species on visual cues. Taken together, all four chapters demonstrate the high context dependency of the effects of complexity on behaviour. Nevertheless, whether or not an individual is territorial emerged as an important predictor of how habitat complexity is likely to affect its behaviour.

Book Description
This book addresses the fundamental issues of predator-prey interactions, with an emphasis on predation among arthropods, which have been better studied, and for which the database is more extensive than for the large and rare vertebrate predators. The book should appeal to ecologists interested in the broad issue of predation effects on communities.
