Intraspecific trait variation can weaken interspecific trait correlations when assessing the whole‐plant economic spectrum
The worldwide plant economic spectrum hypothesis predicts that leaf, stem, and root traits are correlated across vascular plant species because carbon gain depends on leaves being adequately supplied with water and nutrients, and because construction of each organ involves a trade-off between performance and persistence. Despite its logical and intuitive appeal, this hypothesis has received mix...

چرای دامهای اهلی و خشکسالی در ایران، به عنوان مهمترین عوامل در تغییر و شکلگیری پوشش گیاهی مطرح هستند. عوامل زیستی و غیر زیستی باعث تغییرات قابل پیشبینی در صفات گیاهی در پیش- (plant functional types (pfts)) امتداد گرادیان محیطی میشوند. گروههای عملکردی گیاهی بینی تغییرات در فرایندهای اکوسیستم را مستقیماً از طریق تغییرات منعکس شده در ترکیب گونههای گیاهی در پاسخ به تغییرات محیطی امکانپذیر میکند....
15 صفحه اولPhytoplankton functional types : a trait perspective
Phytoplankton functional types are groupings of many species into a smaller number of types according to their ecological or biogeochemical role. Models describe phytoplankton functional types by a set of traits that determine their growth rates or fitness. Traits for functional types are often determined from observations on a small number of species under laboratory conditions. Functional typ...
متن کاملLeaf trait relationships in Australian plant species
Leaf trait data were compiled for 258 Australian plant species from several habitat types dominated by woody perennials. Specific leaf area (SLA), photosynthetic capacity, dark respiration rate and leaf nitrogen (N) and phosphorus (P) concentrations were positively correlated with one another and negatively correlated with average leaf lifespan. These trait relationships were consistent with pr...
