  • Island biogeography is an important subject for several reasons. First, it has been and remains a field which feeds ideas, theories, models, and tests of same into ecology, evolutionary biology, and biogeography. This is because islands provide natural scientists with model systems—replicated and simplified contexts—allowing us to isolate particular factors and processes and to explore their effects.

  • The theory and practice of molecular ecology draw on a number of subjects, particularly genetics, ecology and evolutionary biology. Although the foundations of molecular ecology are not particularly new, it did not emerge until the 1980s as the discipline that we now recognize. Since that time the growth of molecular ecology has been explosive, in part because molecular data are becoming increasingly accessible and also because it is, by its very nature, a collaborative discipline.

  • Content marketing is all the rage. In a distracted world, where consumers are bombarded with advertising and overwhelmed by media and device choices, brands are searching for a new ways to connect—ideally over the long term. And many marketers are turning to content with varying degrees of success.

  • The second section of the book involves the regional biogeography of individual taxa. This section begins with a chapter by Alberto Taylor and his colleagues on the biogeography of cycads in Central America. Their natural history and experimental ecological methods integrate the evolutionary context of the cycad lineage with contemporary autecology, and they elucidate biogeographic patterns and conservation priorities, the latter of which are under-appreciated but pressingly important in Central America.

  • This book explores four overlapping themes in biogeography among multiple plant and animal groups, across subcontinental to global spatial scales, and over evolutionary time. These four themes include: 1) biogeographic theory and tests of concepts and processes; 2) the regional biogeography of individual taxa; 3) historical and contemporary biogeography of complex landscapes; and 4) the evolutionary biogeography of macrotaxa. In the first chapter of the conceptual biogeography section, Khalid Al Mutairi et al.

  • They use geological and distribution data on the island’s 1,284 plant genera and more than 2,000 endemic plant taxa to identify 19 biomes there, and they describe complex conservation challenges. The next chapter by Benny Chan and Pei-Fen Lee explores the biogeography of the barnacles of Taiwan, relating taxon distributions to coastal geomorphology and the complex array of oceanic currents around the island. Global climate changes in ocean water temperature may permit southerly, warmwater taxa to expand northward, invading habitat presently occupied by coldwater taxa....

  • The ability of privately insured individuals to obtain faster access to care is significantly influenced by governmental policies and approaches. Allowing public providers to treat both private and public patients and to receive different remuneration levels for these separate activities can encourage their involvement in the private sector. This spurs the development of a market for PHI products offering access to more timely elective care in the private sector.

  • Numerous authors proposed chapters on their work, and those presented here are the fruit of those proposals. As editor of this book, it has been my pleasure to collaborate with these many, fine contributing scientists. This text brings forth a great amount of fresh information on the biogeography and ecology of poorly known taxa and landscapes, and explores biogeographic processes not previously studied. The assembled work is an anthology of issues in modern biogeography, with topics ranging across regional to global spatial scales, and ecological to evolutionary temporal scales.

  • More than ten years ago, two of us (AGH and DGR) were lucky enough to edit a previous symposium of the British Ecological Society (BES) – Aquatic Ecology: Scale, Pattern and Process (Giller, Hildrew & Raffaelli, 1994). In the Introduction to that volume, we pointed out that the BES had not devoted a single previous symposium to aquatic ecosystems.

  • Air samples for formaldehyde and acetaldehyde were collected on treated silica-gel cartridges (P/N WAT047205, Waters Corp.) using separate pumps. Sampling flow rates were 2.0 L min-1 collected over 15 min to 30 min yielding sample volumes of about 30 L to 60 L. Each cartridge was extracted with 2 mL of acetonitrile. Extracts were analyzed by high- performance liquid chromatography with a diode array detector at a wavelength of 365 nm following ASTM D 5197 (ASTM, 1997a). Extract concentrations were determined from multi- point calibrations of external standard mixtures. ...
