We quantified the damage caused by a major ice storm to individual trees in two 1-ha permanent plots located at Mont St. Hilaire in southwestern Québec, Canada. The storm, which occurred in January 1998, is the worst on record in eastern North America; glaze ice on the order of 80-100 mm accumulated at our study site. All but 3% of the trees (DBH > or = 10 cm) lost at least some crown branches,...

Two strains were selected--the lactoso-negative yeast Rhodotorula rubra GED2 and the homofermentative Lactobacillus casei subsp. casei Ha1 for co-cultivation in cheese whey ultrafiltrate (WU) and active synthesis of carotenoids. Under conditions of intensive aeration (1.0 l/l min, 220 rpm), a temperature of 30 degrees C, WU with 55.0 g lactose/l, initial pH = 5.5, the carotenoid content in the ...

Tilia is an ecologically and economically important genus in the family Malvaceae. However, there is no complete plastid genome of Tilia sequenced to date, and the taxonomy of Tilia is difficult owing to frequent hybridization and polyploidization. A well-supported interspecific relationships of this genus is not available due to limited informative sites from the commonly used molecular marker...

Abstract Alien tree species have been introduced to Europe and often used as roadside trees. Currently, preference is given that are adapted urban climate drier conditions. Native epiphytic lichens local species; however, little known whether a shift toward more alien trees would affect the diversity of within cities. We considered three genera common in Hamburg (Germany) Acer, Tilia, Quercus, ...

Magyarország területéről eddig 3 budavirág faj előfordulása volt ismert. A fiatal parla­gokon, nyílt felszíneken élő Spergularia rubra (L.) J. Presl et C. elterjedt faj, míg a szikeseken szór­ványosan előforduló S. marina Bess. és media az utóbbi években magasabbrendű útjaink mellett terjedőben van. budavirágfajok herbáriumi revíziója során közép-európai elterjedé­sű echinosperma példányait tal...

Three poorly known species of the subfamily Eriophyinae living on Tilia spp. (Tiliaceae) are illustrated and supplementary descriptions are provided. Two of them, Eriophyes exilis (Nalepa 1892) and Eriophyes nervalis (Nalepa 1918), were recorded both in vein angle galls on leaves of Tilia platyphyllos Scop. and in erinea on leaves of Tilia tomentosa Moench, Tilia americana L. 'Moltkei', Tilia a...
