Global sustainability strategies require assessing whether countries' development trajectories are sustainable over time. However, sustainability assessments are limited because losses of natural capital and its ecosystem services through deforestation have not been comprehensively incorporated into national accounts. We update the national accounts of 80 nations that underwent tropical defores...

The latitudinal diversity gradient has been hypothesized to reflect past evolutionary dynamics driven by climatic niche conservation during cladogenesis, i.e. the tropical conservatism hypothesis. Here we show that the species diversity of treefrogs (Hylidae) across the western hemisphere is actually independent of evolutionary niche dynamics. We evaluated three key predictions of the tropical ...

With the advent of increasingly sophisticated techniques for access, tropical forest canopy research has burgeoned in the last few years. Although an enormous amount of basic descriptive work remains to be done, canopy research is now entering a more advanced and ecological phase.

Katphala or Kaiphala, botanically equated with plant Myrica esculenta Buch. - Ham., is an important bark drug of Indian systems of medicine. It is one of the plant species, which are under imminent danger of extinction from U. P. Himalayas. Since, no pharmacognostic study on this drug is on record, the present investigations has been undertaken. In this article, macroscopic and microscopic char...

Current research efforts to understand the relative invasibility of different plant communities have mostly ignored tropical forests. Only a few studies have treated invasive species in tropical forests, and recent worldwide analyses have not provided clear predictions concerning the relative invasibility of tropical forests. In this review, the extent to which exotic species have invaded tropi...

We aimed to explore Campylobacter genotype-specific risk factors in Australia. Isolates collected prospectively from cases recruited into a case-control study were genotyped using flaA restriction fragment-length polymorphism typing (flaA genotyping). Exposure information for cases and controls was collected by telephone interview. Risk factors were examined for major flaA genotypes using logis...

Entomologist, Spirochetosis Transmission Enquiry Calcutta School of Tropical Mcdicinc. In October 1929, whilst on leave, I carried out a study of the anopheline fauna and malaria in Blmgalpur. The results of this investigation may be of some interest, as there is no previous detailed record of the anopheline fauna nor of the malaria of the place. Bhagalpur, the chief town and administrative hea...

THIS is an excellent book although unhappily the only coloured plates concern artists' impressions of various Plasmodia; there is available, however, a set of 180 colour illustrations which can be obtained separately, but the reviewer did not have the pleasure of secinz these. It must be added that many of the black-and-white illustrations given in the text are of outstanding quality; several m...

Tropical myiasis is likely to present in the larger second instar larval stage in the United Kingdom. The use of ultrasound to confirm the size and determine method of removal is described.
