The Role of Litter in Nutrient Cycling in a Brackish
The role of litter in nutrient cycling in a Typha angustifolia dominated brackish tidal marsh was studied with a field experiment. In replicated plots, litter was either removed, replaced with plastic strips (pseudolitter), increased threefold, or left unaltered. One set of plots received fortnightly surface applications of ammonium phosphate solution at an annual rate of 65 g/m2 of N and 72 g/...
متن کاملPlant species effects on nutrient cycling: revisiting litter feedbacks.
In a review published over two decades ago I asserted that, along soil fertility gradients, plant traits change in ways that reinforce patterns of soil fertility and net primary productivity (NPP). I reevaluate this assertion in light of recent research, focusing on feedbacks to NPP operating through litter decomposition. I conclude that mechanisms emerging since my previous review might weaken...
متن کاملChanges in litter quality induced by nutrient addition alter litter decomposition in an alpine meadow on the Qinghai-Tibet Plateau
The effects of nitrogen (N) and phosphorus (P) addition on litter decomposition are poorly understood in Tibetan alpine meadows. Leaf litter was collected from plots within a factorial N × P addition experiment and allowed to decompose over 708 days in an unfertilized plot to determine the effects of N and/or P addition on litter decomposition. Results showed that nutrient addition significantl...
متن کاملMixing Effects of Understory Plant Litter on Decomposition and Nutrient Release of Tree Litter in Two Plantations in Northeast China
Understory vegetation plays a crucial role in carbon and nutrient cycling in forest ecosystems; however, it is not clear how understory species affect tree litter decomposition and nutrient dynamics. In this study, we examined the impacts of understory litter on the decomposition and nutrient release of tree litter both in a pine (Pinus sylvestris var. mongolica) and a poplar (Populus × xiaozhu...
متن کاملNon-Rainfall Moisture Activates Fungal Decomposition of Surface Litter in the Namib Sand Sea
The hyper-arid western Namib Sand Sea (mean annual rainfall 0-17 mm) is a detritus-based ecosystem in which primary production is driven by large, but infrequent rainfall events. A diverse Namib detritivore community is sustained by minimal moisture inputs from rain and fog. The decomposition of plant material in the Namib Sand Sea (NSS) has long been assumed to be the province of these detriti...
