Threat to cedar, Cedrela odorata, plantations in Vietnam by the weevil, Aclees sp. [PDF]
J Insect Sci, 2010 The recent decline and death of young cedar, Cedrela odorata L. (Sapindales: Meliaceae), plantations in Vietnam is caused by Aclees sp. (Coleoptera: Curculionidae), a wood-boring brown weevil. A field study was undertaken in three-year-old plantations in two districts in Thanh Hoa province in August 2008.

An eco-evolutionary optimality model explains the acclimated temperature response of photosynthesis. [PDF]
New PhytolSummary The optimal temperature of photosynthesis (Topt) generally increases with plant growth temperature. Changes in Topt are associated with changes in the maximum carboxylation capacity at 25°C (Vcmax25) and the maximum electron transport rate at 25°C (Jmax25). The ratio between Jmax25 and Vcmax25 declines with warming.
