Leaf litter decomposition and microbial activity in nutrient‐enriched and unaltered reaches of a headwater stream
SUMMARY 1. Decomposition of red maple (Acer rubrum) and rhododendron (Rhododendron maximum) leaves and activity of associated microorganisms were compared in two reaches of a headwater stream inExpand

Relationships between growth and sporulation of aquatic hyphomycetes on decomposing leaf litter
The dynamics of changes in microbial biomass (ATP concentrations), respiration rates and sporulation rates of aquatic hyphomycetes associated with tulip poplar leaf disks in two streams withExpand

Effect of dissolved nutrients on two aquatic hyphomycetes growing on leaf litter
Concentrations of potassium nitrate, potassium phosphate, or calcium chloride were varied in stream-simulating microcosms containing leaf discs colonized by the aquatic hyphomycetes AnguillosporaExpand

Effect of temperature on seasonal occurrence of aquatic hyphomycetes
Seasonal and successional changes in species composition of aquatic hyphomycetes colonizing leaf litter are reported from a small stream in southwestern Michigan, U.S.A. The successional pattern onExpand

Changes in the Chemical Composition of Leaves During Processing in a Woodland Stream
The weight loss and changes in the concentrations of major classes of macro—molecules were assessed in white oak (Quercus alba) and pignut hickory (Carya glabra) during processing in a third orderExpand

Experimental nutrient additions accelerate terrestrial carbon loss from stream ecosystems
Carbon kicked out by nutrients Excess nutrients added to streams result in net carbon loss from aquatic ecosystems. Nitrogen and phosphorus are known to fuel increases in algal carbon. Now, RosemondExpand

Annual production of leaf‐decaying fungi in a woodland stream
1. Fungi are thought to be important mediators of energy flow in the detritus-based food webs of woodland streams. However, until recently, quantitative methods to assess their contribution have beenExpand

Microbial biomass and production associated with decaying leaf litter of the emergent macrophyte Juncus effusus
Emergent macrophytes are a major source of organic matter production in freshwater wetlands, and often represent the bulk of the plant material entering the detrital pool. We examined theExpand
