SYNOPSIS. Sea anemones (Phylum Cnidaria; Class Anthozoa, Order Actiniaria) exhibit a diversity of developmental patterns that include cloning by fission. Because natural histories of clonal and aclonal sea anemones are quite different, the gain and loss of fission is an important feature of actiniarian lineages. We have used mitochondrial DNA and nuclear intron DNA phylogenies to investigate th...

A suite of physical-biological models was used to explore the importance of mortality and fluid dynamics in controlling concentrations of fecal indicator bacteria (FIB) at Huntington Beach, CA. An advection-diffusion (AD) model provided a baseline to assess improvements in model skill with the inclusion of mortality. Six forms of mortality were modeled. All mortality models performed better tha...

Developed decades ago for spatial choice problems related to zoning in the urban planning field, multicriteria analysis (MCA) has more recently been applied to environmental conflicts and presented in several documented cases for the creation of protected area management plans. Its application is considered here for the development of zoning as part of a proposed marine protected area managemen...

From a notice in the British and Foreign Medico-Clururgical Review, we learn that Don R. H. Poggio has lately published, at Madrid, a work on " Red Fever" or dengue. The book is "regarded as a valuable addition t) the history of this strange exotic. It-contains ample references, and the tone is thoughtful and philosophical throughout." Don Poggio informs us that dengue broke out as an epidemic ...

The physical, biological, and oceanographic characteristics of seamounts of the New Zealand region of the South Pacific Ocean are poorly known. The aim of this study was to present a synopsis of the physical characteristics of seamounts within the region, and to present a preliminary classification using biologically meaningful variables. Data for up to 16 environmental variables were collated ...

Facilitation cascades generated by co-occurring foundation species can enhance the abundance and diversity of associated organisms. However, it remains poorly understood how differences among native and invasive species in their ability to exploit these positive interactions contribute to emergent patterns of community structure and biotic acceptance. On intertidal shorelines in New England, we...

An investigation was conducted in the Aberdeen area on wives of oil men working either off-shore or on-shore. No differences were found in measures of general health; but 'off-shore wives' were shown to experience mood and behavioural changes, linked to the pattern of swiftly recurring partings and reunions. While a majority of such wives appeared to tolerate or even thrive on their style of li...
