Nutrient enrichment alters storage and fluxes of detritus in a headwater stream ecosystem.
Responses of detrital pathways to nutrients may differ fundamentally from pathways involving living plants: basal carbon resources can potentially decrease rather than increase with nutrient enrichment. Despite the potential for nutrients to accelerate heterotrophic processes and fluxes of detritus, few studies have examined detritus-nutrient dynamics at whole-ecosystem scales. We quantified or...
متن کاملWhole-system nutrient enrichment increases secondary production in a detritus-based ecosystem.
Although the effects of nutrient enrichment on consumer-resource dynamics are relatively well studied in ecosystems based on living plants, little is known about the manner in which enrichment influences the dynamics and productivity of consumers and resources in detritus-based ecosystems. Because nutrients can stimulate loss of carbon at the base of detrital food webs, effects on higher consum...
متن کاملNutrient enrichment reduces constraints on material flows in a detritus-based food web.
Most aquatic and terrestrial ecosystems are experiencing increased nutrient availability, which is affecting their structure and function. By altering community composition and productivity of consumers, enrichment can indirectly cause changes in the pathways and magnitude of material flows in food webs. These changes, in turn, have major consequences for material storage and cycling in the eco...

15 صفحه اولIsolation from mammalian predators differentially affects two congeners
Evolutionary isolation from predators can profoundly influence the morphology, physiology, and behavior of prey, but little is known about how species respond to the loss of only some of their predators. We studied antipredator behavior of tammar wallabies (Macropus eugenii) and western gray kangaroos (Macropus fuliginosus) on Kangaroo Island (KI), South Australia, and at Tutanning Nature Reser...
