- Abstract:
- ... Population densities, reproduction, and survival of the lizard Uta stansburiana were measured at the Nevada Test Site in southern Nevada, USA, between 1964 and 1974. These data were used to develop a model of the population dynamics of this species. Results of irrigation experiments in 0.4—ha enclosures near Mercury, Nevada, were used to formulate multiple—regression equations predicting frequency ...

- Abstract:
- ... The mechanism that control the distribution and abundance of major benthic organisms in subtidal coral reef communities are poorly understood. Through field experimentation and manipulations, this study investigated the factors that account for the vertical zonation patterns found on a fringing reef in the Gulf of Panama (Pacific). In this community, pocilloporid corals form a near—monotypic stand ...

- Abstract:
- ... The developmental history of Lake Valencia, Venezuela, over the past 12 500 yr was studied by means of animal remains and some chemical and physical variables in three sediment cores. Radiocarbon dates of abandoned beach terraces also provided information for the interpretation of former lake levels. Transects of surficial sediments in the lake served as modern analogues for both animal communitie ...

- Abstract:
- ... The development of general theories concerning the origin and maintenance of community organization in marine sedimentary environments will benefit from studies of similar processes in the widest possible range of habitat types. The roles of predation and disturbance by large epibenthos are thought to be significant in many such habitats, but the bulk of recent experimental confirmation comes from ...

- Abstract:
- ... Using mark—recapture experiments, I studied the foraging movements of two crucifer feeding flea beetles, Phyllotreta cruciferae and P. striolata. To determine the influence of distance between host patches, and their quality, on beetle movement, I released marked beetles in experimental arrays of collards (Brassica oleracea). I quantified and interpreted movement behavior by applying a passive dif ...
