Forest Ecosystems: Nutrient Cycling
Nutrients are elements or compounds that are essential for the growth and survival of plants. Plants require large amounts of nutrients such as nitrogen (N), phosphorus (P), carbon (C), hydrogen (H), oxygen (O), potassium (K), calcium (Ca), and magnesium (Mg), but only small amounts of others such as boron (B), manganese (Mn), iron (Fe), copper (Cu), zinc (Zn) and chlorine (Cl) (micronutrients)...
متن کاملEcohidrology and Nutrient Fluxes in Forest Ecosystems of Southern Chile
Nitrogen (N) cycling in terrestrial ecosystems is a global environmental concern. The N cycle is a complex interplay where biotic and abiotic processes interact to transform and transfer N in an ecosystem. In general, one can simplify by classifying terrestrial N cycles all over the world in two groups: ‘tight’ N cycles and ‘open’ N cycles. The ‘tight’ N cycle is characterized by its high effic...
متن کاملDust outpaces bedrock in nutrient supply to montane forest ecosystems
Dust provides ecosystem-sustaining nutrients to landscapes underlain by intensively weathered soils. Here we show that dust may also be crucial in montane forest ecosystems, dominating nutrient budgets despite continuous replacement of depleted soils with fresh bedrock via erosion. Strontium and neodymium isotopes in modern dust show that Asian sources contribute 18-45% of dust deposition acros...
متن کاملEffects of Eucalyptus Plantation on Termites in Dead Wood on the Forest Floor
Expansion of Eucalyptus plantation is considered to be one of the major human disturbances to tropical forests, where termites are superabundant and an important decomposer. Here we studied the biomass of dead wood and the abundance and species composition of termites in dead wood in Eucalyptus plantation forest (EF) in Thailand and compared the data with those of the neighboring dry evergreen ...
متن کاملConsumer-driven nutrient dynamics in freshwater ecosystems: an introduction
1. Over the past decade, studies of the effects of consumer-driven nutrient dynamics have become more common. This work has demonstrated that animals can function as sources and sinks of elements, but few studies have broadly compared these processes among organisms and across ecosystems. 2. Collectively, the articles in this special issue elucidate the important roles that organisms can play i...
