Abstract A description is provided for Davisomycella asiatica. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pinus sp. DISEASES: Needle cast of pines. Very little is known of the biology of this recently-described and interesting species, which has some features intermediate between Davisomycella Darker and Elytroderma Darker, but in view of the parasitic behaviour of other members of the same genus in North America, and of the strongly parasitic biology of members of the genus Elytroderma, it must be regarded as a potential pathogen of pines in south-east Asia. GEOGRAPHICAL DISTRIBUTION: Thailand. TRANSMISSION: By airborne ascospores in wet or humid conditions.

Abstract A description is provided for Lophodermium indianum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pinus caribaea, P. glabra, P. patula, P. roxburghii, P. serotina, P. taeda; previous reports of this species on P. thunbergii are incorrect. DISEASE: Needle cast of pines. Ascocarps of this species occur predominantly on dead needles in the litter, so that at first sight it appears to be saprophytic. Almost nothing is known of its ecology, however, and since many other species of this genus inhabitating pine needles are known to exist as endophytes in apparently healthy needles before producing ascocarps, this species should be regarded as a potential pathogen until shown to be otherwise. GEOGRAPHICAL DISTRIBUTION: Asia (India: Haryana, Himachal Pradesh, Jammu & Kashmir, Madhya Pradesh, Uttar Pradesh; Pakistan: Rawalpindi). TRANSMISSION: By air-borne ascospores in wet or humid weather.

Abstract A description is provided for Bifusella linearis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pinus albicaulis, P. flexilis, P. monticola, P. strobus. DISEASE: Needle blight and needle cast of white pines, tar spot needle cast, Bifusella blight. The disease apparently occurs only under moist conditions, and since its effects are usually limited to defoliation of needles two or three years old, it is not devastating. Probably infects young needles but macrosymptoms do not show up until the following spring when needles become blighted from the tip part-way to the base. The disease tends to occur principally in the lower crown (47, 2867). GEOGRAPHICAL DISTRIBUTION: North America (Canada: British Columbia, Ontario, U.S.A. : California, Colorado, Idaho, Maine, Massachusetts, Minnesota, New Hampshire, New York, North Carolina, Pennsylvania, Washington, Wisconsin). TRANSMISSION: By air-borne ascospores in wet or humid weather.

The world's gliding mammals are an extraordinary group of animals that have the ability to glide from tree to tree with seemingly effortless grace. There are more than 60 species of gliding mammals including the flying squirrels from Asia, Europe and North America, the scaly-tailed flying squirrels from central Africa and the gliding possums of Australia and New Guinea. But the most spectacular of all are the colugos – or so called flying lemurs – that occur throughout South-East Asia and the Philippines. Animals that glide from tree to tree descend at an angle of less than 45 degrees to the horizontal, while those that parachute descend at an angle greater than 45 degrees. Gliding is achieved by deflecting air flowing past well-developed gliding membranes, or patagia, which form an effective airfoil that allows the animal to travel the greatest possible horizontal distance with the least loss in height. The flying squirrels and scaly-tailed flying squirrels even have special cartilaginous spurs that extend either from the wrist or elbow, respectively, to help support the gliding membrane. Gliding Mammals of the World provides, for the first time, a synthesis of all that is known about the biology of these intriguing mammals. It includes a brief description of each species, together with a distribution map and a beautiful full-colour painting. An introduction outlines the origins and biogeography of each group of gliding mammals and examines the incredible adaptations that allow them to launch themselves and glide from tree to tree.

Indications from the first half of the year suggested that the present cyclical expansion was starting to slow in much of the OECD. The pace of activity moderated particularly sharply in North America. Canadian GDP fell slightly in the second quarter of the year and inventory levels rose considerably. Trade growth was also lower than expected, although this partially reflected the regional impact of recent developments in Mexico. Within Europe, GDP growth slowed in the UK, France and Italy, although growth proved unexpectedly robust in a number of the smaller economies, particularly Ireland, Sweden and Finland. Output also continued to grow sharply in Australia and South East Asia.

Abstract. A coupled tropospheric chemistry-climate model is used to analyze tropospheric ozone distributions observed during the MINOS campaign in the eastern Mediterranean region (August, 2001). Modeled ozone profiles are generally in good agreement with the observations. Our analysis shows that the atmospheric dynamics in the region are strongly influenced by the occurrence of an upper tropospheric anti-cyclone, associated with the Asian summer monsoon and centered over the Tibetan Plateau. The anti-cyclone affects the chemical composition of the upper troposphere, where ozone concentrations of about 50 ppbv were measured, through advection of boundary layer air from South-East Asia. A layer between 4-6 km thickness was present beneath, containing up to 120 ppbv of ozone with substantial contributions by transport from the stratosphere and through lightning NOx. Additionally, pollutant ozone from North America was mixed in. Ozone in the lower troposphere originated mainly from the European continent. The stratospheric influence may be overestimated due to too strong vertical diffusion associated with the relatively coarse vertical resolution. The estimated tropospheric ozone column over the eastern Mediterranean is ~50 DU in summer, to which ozone from recent stratospheric origin contributes about 30%, ozone from lightning 13%, and from South-East Asia, North America and Europe about 7%, 8% and 14%, respectively, adding to a long-term hemispheric background of 25% of the column.

AbstractA gall midge recently found on Dendrobium orchids in Florida, USA, is identified as Contarinia maculipennis Felt. The identification is based on anatomical similarity to a polyphagous species originally described from Hawaii but which now appears to be from south-east Asia. Contarinia maculipennis is redescribed and compared to Contarinia solani (Rübsaamen) and C. lycopersici Felt, two species with which it has been confused in the literature.
