(2003-11-18)At the southern fringe of the Taklamakan desert, the annual precipitation is only 33 mm, and the potential evaporation 2600 mm. The oases are supplied with water through rivers, which run from the Kunlun Mountains and carry ... -
Water turnover in species-rich and species-poor deciduous forests: xylem sap flow and canopy transpiration
(2010-01-05)The importance of plant diversity for ecosystem functioning has been one of the central research topics in ecology during the past 15 years. While much research has focused on the role of ... -
Wechselwirkung zwischen Schwarzerlen und Erlenblattkäfer: Signaltransfer zwischen Bäumen und induzierte Resistenz
(2002-01-23)The presented work investigates the hypothesis of interplant communication between trees. According to this hypothesis, damaged plants release airborne chemical signals which can induce ... -
Weekly headache in children and adolescents: Biopsychosocial correlates and their specificity
(2007-04-27)Pediatric weekly headache is an impairing chronic illness that is increasing in prevalence. Knowledge of associated biopsychosocial variables and their specificity is necessary for the ... -

Within- and between-group feeding competition in Siberut macaques (Macaca siberu) and Assamese macaques (Macaca assamensis)
(2014-02-26)Feeding competition remains of research interest as it affects growth, survival and reproductive success of individuals. It also limits group size and shapes the social structure of animal groups. Feeding competition is ... -
Yeast Chorismate Mutase: Molecular Evolution of an Allosteric Enzyme
(2003-01-30)Chorismate mutase (CM, EC 5.4.99.5), encoded by ARO7, catalyzes the Claisen rearrangement of chorismate to prephenate in the biosynthesis of the amino acids tyrosine and phenylalanine. The ... -
Yeast cleavage factor Hrp1 is a novel guard protein that surveils pre-mRNA 3’ processing
(2022-05-10)Hrp1 is a component of the cleavage and polyadenylation complex (CPF-CF) for pre-mRNA cleavage and polyadenylation in S. cerevisiae. It specifically binds to a relatively conserved UA-rich domain called the efficiency-element ... -
Zeitwahrnehmung in isochronen Sequenzen
(2009-09-03)The predictions of three different psychological models for time perception were compared with the results of seven experiments. In each experiment the participants listened to a sequence ... -
