Linking Heterotrophic Metabolism and Nutrient Uptake in Headwater Streams
Autotrophs and heterotrophs differ in their demand, acquisition and use of materials, but fundamentally nutrient demand is inherently linked to metabolism based on the stoichiometry of biochemical reactions. The differences between these two groups of organisms confound straightforward regression …

Genetics by Nutrient Availability Interactions on Short-term Carbon Pools and Fluxes in Young Pinus taeda Plantations
… this research was to determine how genetics and nutrient availability influence C cycling in intensively managed southern pine forests. This work consisted of a two year field and a complimentary one year greenhouse study each split into above- and below-ground pools and fluxes. Both the …

The Spatiotemporal Dynamics of Nutrient Exchange at the Arbuscule
… arbuscular mycorrhizal (AM) fungi to meet this nutrient demand. AM symbiosis involves the fungus-to-plant transfer of phosphorus and nitrogen, and the reciprocal plant-to-fungus transfer of carbon at specialised structures within plant root cells, the arbuscules. While many studies have …

The effectiveness of actively accumulating dust in rejuvenating soils and ecosystems in a super-humid, high weathering and leaching environment, West Coast, South Island, New Zealand
… as an important rejuvenator by supplying nutrients and unweathered mineral material to ecosystems. While deposition rates have been regularly quantified for terrestrial environments in the past, the rejuvenating effect of dust on soils and terrestrial ecosystems and the accessional …

Dynamics of internal nutrient loading in a eutrophic, polymictic lake (Lake Rotorua, New Zealand)
… This study examines the dynamics of internal nutrient recycling processes in Lake Rotorua, including sediment nutrient release, sedimentation and resuspension, phytoplankton nutrient limitation and the relative importance of internal and external nutrient loads on influencing cyanobacteria …
