The tropical climate in China exists in southeastern Xizang (Tibet), southwestern to southeastern Yunnan, southwestern Guangxi, southern Guangdon, southern Taiwan, and Hainan, and these southern Chinese areas contain tropical floras. I checked and synonymized native seed plants from these tropical areas in China and recognized 12,844 species of seed plants included in 2,181 genera and 227 famil...

A bimodal distribution of tropical tree cover at intermediate precipitation levels has been presented as evidence of fire-induced bistability. Here we subdivide satellite vegetation data into those from human-unaffected areas and those from regions close to human-cultivated zones. Bimodality is found to be almost absent in the unaffected regions, whereas it is significantly enhanced close to cu...

Tropical butterflies in the genus Heliconius have long been models in the study of the stages of speciation. Heliconius are unpalatable to predators, and many species are notable for multiple geographic populations with striking warning colour pattern differences associated with Müllerian mimicry. A speciation continuum is evident in Heliconius hybrid zones. Examples range from hybrid zones acr...

INTRODUCTION Pyomyositis, or isolated abscess formation within a skeletal muscle, is a relatively common condition in tropical climates but it is only encountered rarely in temperate zones. CASE PRESENTATION We present a case of non-tropical pyomyositis of the gluteal muscle in a 26-year-old, previously healthy man from the United Kingdom, who initially presented with sciatica-like symptoms w...

GPS/MET observations of the tropical atmosphere of the southern hemisphere (5S to 25S) during February 1997 are analysed, when a high amount of convective tropospheric water vapor is at these latitudes. Enhanced gravity wave activity of the lower stratosphere at h=22-28 km is associated to areas of increased tropospheric water vapor pressure at h=4-6 km, regarded as a measure of tropical convec...

The tropics, sadly, continues to be a belt of poverty. The countries of the tropics all have low or middling incomes, with a few tiny or natural-resource-rich exceptions, and few of the poorest countries are outside of the tropics. The causes of tropical poverty are surely complex, involving initial endowments (Diamond), history, especially colonization, and geographical isolation (Gallup and S...

Dalbergia sissoo Roxb (Indian rosewood) is an important tree species belonging to the family papilionaceae. It is a medium to large‐sized, gregarious deciduous tree, attaining a height up to 30 m and a girth up to 2•5 m in a favorable climate (sub‐tropical and tropical zones). According to Champion & Seth [1], the Shisham tree is a characteristic species of Khair-sissoo (Acacia catechu‐Dalbergi...

The general objective of the work underway is to develop a baseline characterization of the spatial and temporal variability in optical/acoustical water properties for tropical island environments in response to variations in physical forcing. OBJECTIVES Specifically, the project aims to address the following questions:-What are the dominant space and time scales for variability in optical and ...

The permanent deformation pavement of roads and streets at tropical zones Abstract (if layers are sufficiently compacted) is due to increase of asphalt layers temperature and consequential decrease of modulus of elasticity. Therefore, the asphalt mixture moves aside of the wheels of heavy vehicles and cause permanent deformations without volume variation. On the other hand, if the asphalt layer...

Prevalence of epilepsy in developing countries is considered to be 2 to 5 times superior to the industrialized countries. In tropical areas, the diagnosis of epilepsy is still reliant on the clinic and requires a precise semiological description. A good epidemiological and clinical research requires standardized and validated screening tools. The objective of this work was to evaluate the valid...
