Effects of discharge and substrate characteristics on FPOM retention
… transport of fine particulate organic matter (FPOM). I found that doubling discharge significantly decreased both hydraulic and FPOM retention (measured as pollen uptake length). However, quadrupling discharge returned both hydraulic and FPOM retention to original or higher values. There was a …

The Role of Leaf Litter and Small Wood in the Retention of Fine Particles During Storms in an Appalachian Headwater Stream
… to retain fine particulate organic matter, FPOM. However, leaves are also a major source of FPOM. I studied the effect of leaf exclusion on FPOM transport by field sampling and by generating computer simulations of particle transport in the stream. Sampling of suspended particles during …

The use of corn pollen and glass beads to estimate fine particulate organic matter retention
… of natural fine particulate organic matter (FPOM). These particles were released into ten streams in three different physiographic regions, Appalachian Mountains, Rocky Mountains, and Central Plains, within the United States. Mean travel distance for corn pollen was 121 m and that for glass …

An ephemeral perspective of fluvial ecosystems: Viewing ephemeral rivers in the context of current lotic ecology
… fine particulate and dissolved organic matter (FPOM and DOM) deposited in the lower reaches of the rivers serve to fuel this heterotrophic biota. As a result of the hydrologic decay, sediment concentration (both organic and inorganic) increased downstream and the lower reaches of these rivers …

Macroinvertebrate drift along an elevational and stream size gradient in a southern Appalachian stream
… (#/s) was highest in late spring and winter. FPOM and mean daily water temperature accounted for 64% of the variation in total aquatic insect drift density and 60% of <i>Baetis</i> drift density, suggesting both passive and active components in drift. Both variables were also highly correlated …

Effects of native forest and pastoral land use on the population dynamics and trophic role of the New Zealand freshwater crayfish Paranephrops planifrons (Parastacidae)
… of organic matter, and through production of FPOM they may make leaf matter available to a wider range of invertebrates (e.g. collectors) in stream ecosystems. Juvenile crayfish had higher rates of assimilation for leaf detritus and higher ingestion rates of invertebrates and leaf detritus …

The influence of land use on the quality of seston in southern Appalachian stream ecosystems
Seston is the complex of organic and inorganic particles suspended in the water column in stream ecosystems. This detrital pool is a significant vector of energy and nutrients from headwaters to the ocean. Many of the processes involved in seston generation in streams involve the terrestrial …
