Functional traits explain variation in plant life history strategies.
Ecologists seek general explanations for the dramatic variation in species abundances in space and time. An increasingly popular solution is to predict species distributions, dynamics, and responses to environmental change based on easily measured anatomical and morphological traits. Trait-based approaches assume that simple functional traits influence fitness and life history evolution, but ri...
متن کاملThe adaptive value of functional and life-history traits across fertility treatments in an annual plant.
BACKGROUND AND AIMS Plant functional traits are assumed to be adaptive. As selection acts on individuals and not on traits, interpreting the adaptive value of a trait not may be straightforward. For example, productive leaves are associated with fertile environments. However, it is not clear if productive leaves confer an advantage in these habitats, or if they are an advantage as part of a sui...

کفشدوزک خربزه، Epilachna chrysomelina (F.)، یکی از آفات کلیدی گیاهان جالیزی در آسیا و شمال آفریقا میباشد. طول دورهی رشد، تولید مثل و پارامترهای جدول زندگی این کفشدوزک روی گیاهان هندوانه، خیار چنبر، خیار و خربزه در شرایط آزمایشگاهی (دمای 30 درجهی سیلسیوس، رطوبت نسبی 60 درصد و طول دورهی روشنایی به تاریکی 14 به 10 ساعت) مطالعه شد. میانگین طول دورهی زندگی از تخم تا مرحلهی بلوغ ماده روی هندوانه، خیا...
متن کاملMicrobially Mediated Plant Functional Traits
Plants are rife with bacteria and fungi that colonize roots and shoots both externally and internally. By providing novel nutritional and defense pathways and influencing plant biochemical pathways, microbes can fundamentally alter plant phenotypes. Here we review the widespread nature of microbially mediated plant functional traits. We highlight that there is likely fitness conflict between ho...
متن کاملRoot Foraging Performance and Life-History Traits
Plants use their roots to forage for nutrients in heterogeneous soil environments, but different plant species vastly differ in the intensity of foraging they perform. This diversity suggests the existence of constraints on foraging at the species level. We therefore examined the relationships between the intensity of root foraging and plant body traits across species in order to estimate the d...
