1. Spatial patterns of beta-diversity, an important property of species communities, are less well-studied than those of local species richness, particularly in insects from tropical rainforests. 2. We use geometrid moth samples from northern Borneo to quantify ensemble turnover across distances of > 700 km, consider habitat- and sampling-related impacts on their composition, and evaluate remai...

In an earlier paper the use of Marmite, a yeast extract, in the treatment of tropical Macrocytic ansemia was reported (Wills, 1931). Since this publication other workers have recorded varying results with this line of treatment. Vaughan and Hunter (1932), Goodall ,(1932), and others have reported success both macrocytic ansemia in cases of idiopathic steatorrhcea, and in certain cases of true p...

Why integrated care matters The King’s Fund has been instrumental in making the case for integrated care (Ham and Curry 2011; Ham et al 2011; Goodwin et al 2012). Our argument is that the current fragmented services fail to meet the needs of the population and that greater integration can improve the patient experience and the outcomes and efficiency of care. This case was accepted by the NHS F...

BACKGROUND How accurately do people perceive extreme water speeds and how does their perception affect perceived risk? Prior research has focused on the characteristics of moving water that can reduce human stability or balance. The current research presents the first experiment on people's perceptions of risk and moving water at different speeds and depths. METHODS Using a randomized within-...

Conversion of tropical rainforests into plantations fundamentally alters ecological niches of animal species. Generalist predators such as centipedes (Chilopoda) may be able to persist in converted ecosystems due to their ability to adapt and switch to alternative prey populations. We investigated variations in community composition and trophic niches of soil and litter living centipedes in a r...

PRIMARY TROPICAL FORESTS ARE POWERhouses of biodiversity (1) but are rapidly declining in extent and are threatened even within some protected areas (2). As a result, non-primary forests, especially those that have been selectively logged, are becoming more important to conservation efforts. In the tropics, logging is almost always selective, targeting only certain commercially valuable tree sp...

The basic element of Lighthill's "sandwich model" of tropical cyclones is the existence of "ocean spray," a layer intermediate between air and sea made up of a cloud of droplets that can be viewed as a "third fluid." We propose a mathematical model of the flow in the ocean spray based on a semiempirical turbulence theory and demonstrate that the availability of the ocean spray over the waves in...

A sediment sample was obtained at 122 cm from the top of a drilling core in the Guapimirim mangrove, Bay of Guanabara, and analyzed using pollen analysis. This muddy core reached a sandy ground at 133 cm. 14C datation got the age of 1760 +/- 50 years B.P. The most frequent pollen grains were mangrove species of Rhizophora mangle, Laguncularia racemosa and Avicennia schaueriana. "Restinga" and t...

Theory and experiment agree that climate warming will increase carbon fluxes between terrestrial ecosystems and the atmosphere. The effect of this increased exchange on terrestrial carbon storage is less predictable, with important implications for potential feedbacks to the climate system. We quantified how increased mean annual temperature (MAT) affects ecosystem carbon storage in above- and ...

no slight degree due to improved methods of medical treatment, as well as to increased attention to the sanitary requirements of the soldier. It is only right that the medical officers of the army should be made aware that their efforts in combating actual disease have been in some instances quite as successful as in its prevention. In the present state of public feeling, the healing art is apt...
