We examined the effect of natural host-plant quality on immune resistance in the autumnal moth, Epirrita autumnata (Borkhausen) (Lepidoptera: Geometridae). The division of mountain birches [Betula pubescens ssp. czerepanovii (Orlova) Hämet-ahti (Betulaceae)] into two categories, highand low-quality food for larvae, was based on previous years’ results on the relative growth rate of the autumnal...

The insecticidal and antifeedant activity of extracts derived from different plants of Aesculus hippocastanum L. (Hippocastanaceae), Viscum album L. (Loranthaceae), Sambucus nigra L. (Caprifoliaceae), Buxus sempervirens L. (Buxaceae), Diospyros kaki L. (Ebenaceae), Artemisia absinthum L. (Compositae), Alnus glutiosa Goertn. (Betulaceae), Origanum vulgare L., (Labiatae), Hypericum androsaemum L....

As a very important plant resource, wood played varied and roles in the lives of ancient people. In present study, was discovered Yanghai cemetery Turpan Basin, which belonged to Subeixi culture (~1300BC–200AD). By using traditional classification techniques anatomy, four taxa wood, viz. Populus sp., Salix Picea as well Betula were identified. Woods Populus, Salix, mainly used for tomb construc...

Detailed vegetation history response to complex influencing factors of arid Central Asia (ACA) is crucial understanding ecological sustainability. Here, we present the first pollen record in Ili Valley during Last Glacial Maximum (LGM) using Jirentai (JRT) loess-paleosol sequence. Combining results multi-climate proxies and optically stimulated luminescence (OSL) dating, aim reconstruct vegetat...

Eurysthea sordida (Erichson) (Coleoptera: Cerambycidae) es un coleóptero de distribución tropical en Sudamérica que ocasiona daño importancia económica Alnus acuminata Kunth el valle del Mantaro, región Junín, Perú. En la región, no hay estudio completo como ciclo vida y a acuminata. El objetivo esta investigación estudiar morfología los estadios biológicos E. recolectados A. acuminata, así car...

Theresa M. Culley* Stephen G. Weller Ann K. Sakai Dept of Ecology and Evolutionary Biology, University of California–Irvine, Irvine, CA 92697, USA. *e-mail: [email protected] Although much emphasis has been placed on specialist pollination systems, attention is shifting towards systems in which plants are visited by a variety of pollinators [1,2]. Until recently, examples of generalist pollinatio...

Plant–soil feedbacks regulate plant productivity and diversity, but potential mechanisms underpinning such feedbacks, as the allocation of recent assimilate, remain largely untested especially for plants forming tripartite symbioses. We tested how soils from under alder Alnus glutinosa beneath other species same different families affected growth nutrition, colonization roots by nitrogen-fixing...
