Soil animals alter plant litter diversity effects on decomposition.
Most of the terrestrial net primary production enters the decomposer system as dead organic matter, and the subsequent recycling of C and nutrients are key processes for the functioning of ecosystems and the delivery of ecosystem goods and services. Although climatic and substrate quality controls are reasonably well understood, the functional role of biodiversity for biogeochemical cycles rema...
متن کاملEffects of Plant Functional Group Loss on Soil Microbial Community and Litter Decomposition in a Steppe Vegetation
Globally, many terrestrial ecosystems are experiencing a rapid loss of biodiversity. Continued improvements in our understanding of interrelationships between plant diversity and soil microbes are critical to address the concern over the consequences of the decline in biodiversity on ecosystem functioning and services. By removing forbs, or grasses, or, to an extreme scenario, both forbs and gr...
متن کاملEffects of Elevated CO2 on Litter Chemistry and Subsequent Invertebrate Detritivore Feeding Responses
Elevated atmospheric CO2 can change foliar tissue chemistry. This alters leaf litter palatability to macroinvertebrate detritivores with consequences for decomposition, nutrient turnover, and food-web structure. Currently there is no consensus on the link between CO2 enrichment, litter chemistry, and macroinvertebrate-mediated leaf decomposition. To identify any unifying mechanisms, we presente...
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 کاملEffects of plant litter diversity, species, origin and traits on larval toad performance
Decreased plant diversity is expected to reduce ecosystem function. Although many studies have examined eff ects of plant species on trophic interactions, information regarding eff ects of native or non-native plant diversity on performance of individuals of higher trophic levels is limited. We reared larval American toad Anaxyrus americanus tadpoles in outdoor mesocosms containing litter of 1,...
