Drought Stress alters Solute Allocation in Broadleaf
According to climate models, drier summers must be expected more frequently in 5 Central Europe during the next decades which may influence plant performance and 6 competition in grassland. The overall source-sink relations in plants, especially allocation of 7 solutes to aboveand below-ground parts, may be affected by drought. To investigate solute 8 export from a given leaf of broadleaf dock,...
متن کاملSummer drought alters carbon allocation to roots and root respiration in mountain grassland
Drought affects the carbon (C) source and sink activities of plant organs, with potential consequences for belowground C allocation, a key process of the terrestrial C cycle. The responses of belowground C allocation dynamics to drought are so far poorly understood. We combined experimental rain exclusion with (13)C pulse labelling in a mountain meadow to analyse the effects of summer drought o...
متن کاملEarly Effects of Afforestation with Willow (Salix purpurea, “Hotel”) on Soil Carbon and Nutrient Availability
Willow (Salix spp.) is currently being researched as a source of biomass energy in Canada. However, it is not certain whether afforestation with willow plantations will enhance or diminish soil C storage and nutrient availability. Trees are known to have pronounced effects on biologically mediated nutrient cycling processes which can increase nutrient availability, but willows are known to be n...
متن کاملNitrogen alters carbon dynamics during early succession in boreal forest
Boreal forests are an important source of wood products, and fertilizers could be used to improve forest yields, especially in nutrient poor regions of the boreal zone. With climate change, fire frequencies may increase, resulting in a larger fraction of the boreal landscape present in early-successional stages. Since most fertilization studies have focused on mature boreal forests, the respons...
متن کاملNutrient Stress During Ontogeny Alters Patterns of Resource Allocation in two Species of Horned Beetles.
The elaboration of exaggerated, sexually selected weapons and ornaments often comes at a cost to other traits. For instance, by sustaining the growth of an exaggerated weapon during development, shared and limited resources such as morphogens, growth factors, and nutrients may become depleted and limit the size to which other structures can grow. Such interactions are characteristic of resource...
