Short-term fitness benefits of physiological integration in the clonal herb Hydrocotyle peduncularis
We test whether physiological integration enhances the short-term fitness of the clonal herb Hydrocotyle peduncularis (Apiaceae, R. Brown ex A. Richards) subjected to spatial variation in water availability. Our measures of fitness and costs and benefits are based on the relative growth rate of fragmented genets. Physiological integration over a gradient in soil moisture resulted in a highly si...
متن کاملthe effects of keyword and context methods on pronunciation and receptive/ productive vocabulary of low-intermediate iranian efl learners: short-term and long-term memory in focus
از گذشته تا کنون، تحقیقات بسیاری صورت گرفته است که همگی به گونه ای بر مثمر ثمر بودن استفاده از استراتژی های یادگیری لغت در یک زبان بیگانه اذعان داشته اند. این تحقیق به بررسی تاثیر دو روش مختلف آموزش واژگان انگلیسی (کلیدی و بافتی) بر تلفظ و دانش لغوی فراگیران ایرانی زیر متوسط زبان انگلیسی و بر ماندگاری آن در حافظه می پردازد. به این منظور، تعداد شصت نفر از زبان آموزان ایرانی هشت تا چهارده ساله با...
15 صفحه اولPhysiological Integration Ameliorates Negative Effects of Drought Stress in the Clonal Herb Fragaria orientalis
Clonal growth allows plants to spread horizontally and to establish ramets in sites of contrasting resource status. If ramets remain physiologically integrated, clones in heterogeneous environments can act as cooperative systems--effects of stress on one ramet can be ameliorated by another connected ramet inhabiting benign conditions. But little is known about the effects of patch contrast on p...
متن کاملThe quantitative assessment of the benefits of physiological integration in clonal plants
A genet of a clonal plant often has ramets persistently interconnected by living tissue capable of supporting the exchange of materials. This condition is known as physiological integration. A quantitative framework is developed for the study of the fitness benefits of physiological integration in clonal plants in spatially heterogeneous environments. We argue that the relative growth rate of t...
متن کاملHeterogeneous water supply affects growth and benefits of clonal integration between co-existing invasive and native Hydrocotyle species
Spatial patchiness and temporal variability in water availability are common in nature under global climate change, which can remarkably influence adaptive responses of clonal plants, i.e. clonal integration (translocating resources between connected ramets). However, little is known about the effects of spatial patchiness and temporal heterogeneity in water on growth and clonal integration bet...
