Species often harbour large amounts of phenotypic variation in ecologically important traits, and some of this variation is genetically based. Understanding how this genetic variation is spatially structured can help to understand species' ecological tolerances and range limits. We modelled the climate envelopes of Arabidopsis thaliana genotypes, ranging from early- to late-flowering, as a func...

Abstract* Introduction: Cannabis consumption during pregnancy may affect fetal growth, motor performance, memory and cognitive functions. Methods: Primiparous pregnant Wistar rats were randomly assigned to 4 treatment groups (6 rats per group) consisting of control and sham groups as well as 2 groups treated with Win. Win treated groups received daily s.c. injections of 0.5 or 1 mg/kg WIN ...

The role of biotic interactions in shaping plant flowering phenology has long been controversial; plastic responses to the abiotic environment, limited precision of biological clocks and inconsistency of selection pressures have generally been emphasized to explain phenological variation. However, part of this variation is heritable and selection analyses show that biotic interactions can modul...

We analysed phenological observations of first flowering and peak flowering dates of 7 species of woodland herbs in the Bia8owie· za National Park (Poland), Europe’s last remaining lowland primeval forest and a World Heritage Site, during 1964–2007. There was substantial evidence for an advance in both first and peak flowering dates and flowering was closely related to temperature, which had ri...

the aim of this research was determination of nutritive value of cressa cretica with gas test method, in vivo digestibility and degradability with nylon bag method in three phenological stages. the amount of crude protein decreased significantly in seeding stage. but the amount of ndf and adf increased in seeding stage. the degradability of dry matter and rapid and slowly degradable fractions d...

in order to study the different concentrations of gibbererlic acid and girdling on quantity and quality improvement of grape cv, askari an experiment was carried out in kashmar region on 2012 as factorial in a complete randomized block design.in this experiment the effect of gibberellin at four concentration in two time of flowering and girdling at four time in four replication were performed. ...
