The lability of Rubisco activase function is thought to have a major role in the decline of leaf photosynthesis under moderate heat (<35°C). To investigate this further, we characterized Rubisco activase and explored its role in the previously demonstrated thermal acclimation and inhibition of two genotypes of Acer rubrum originally collected from Florida (FL) and Minnesota (MN). When plants we...

We analyzed the spatial patterns among seeds, seedlings, saplings, and conspecific adult trees of the cool-temperate tree species Acer palmatum var. Matsumurae in a conifer–hardwood mixed forest in northern Japan, using two models that consider the influence of each adult within the neighborhood of the offspring. The results showed that recruitment patterns of each stage could be characterized ...

fects, such as methyl brevifolincarboxylate, from the leaves of Phyllanthus niruri, ebricoic acid from the extract of Phellinus givus, and forsythiaside from the fruit of Forsythia suspensa. In our attempts to search for compounds with vasorelaxant effects from various plants, in the present study we isolated three constituents from the heartwood of Acer nikoense (Aceraceae): A. nikoense is a J...

By analyzing the effects of environmental variables on plants, changes in plant distribution as a result climate oscillations can be studied, which is great significance to protection and management policies. Acer cordatum Pax (Aceraceae) non-deciduous tree distributed valleys streams eastern China. Due changing (warmer, drier conditions) human impacts, number wild individuals A. has exhibited ...

A literature survey revealed that the semi-parasitic evergreen shrub Viscum album subsp. album (Viscaceae) has been recorded on 53 taxa of deciduous trees and shrubs (including five hybrids) in the Czech Republic,. Of the host taxa, 26 are native and 27 alien to the Czech flora. The range of hosts covers 13 families. Salicaceae (11 taxa), Rosaceae (11) and Aceraceae (7) are most represented amo...

The present paper supplements recent contributions to the systematics of derelomine flower weevils from the Neotropics (Franz 2001, Franz & O’Brien 2001a, 2001b). Under the current conception, Derelomini (Coleoptera: Curculionidae: Curculioninae sensu Alonso-Zarazaga & Lyal 1999) comprise 220 species and 39 genera, the majority of which are associated with the inflorescences of Arecaceae. Some ...
