The Role of Autochothnous Production in the Formation of Dissolved and Particulate Organics in Laboratory Streams
… determined periodically under conditions where allochthonous inputs could be carefully monitored. Possible relationships between DOC and FPOC production and community structure, primary production, and community respiration were examined. The production of DOC by laboratory stream communities …

Spatial Drivers of Ecosystem Structure and Function in a Floodplain Riverscape: Springbrook Nutrient Dynamics
… dictates severity of flood disturbance and allochthonous inputs from contiguous terrestrial and groundwater systems. Between July and October 2011, I quantified aspects of ecosystem structure and function among six streams (i.e., spring brooks) originating on the Nyack floodplain, Flathead …

In-Stream Hemlock Twig Breakdown and Effects of Reach-Scale Twig Additions on Appalachian Headwater Streams
… one consequence of hemlock death is a change in allochthonous inputs to headwater streams. I predicted that hemlock twigs' dendritic structure, abundance, and resistance to decay currently make them highly effective retainers of leaves in headwater streams, with consequences for nutrient uptake. …

The effects of the invasive exotic Chinese tallow tree (Triadica sebifera) on amphibians and aquatic invertebrates
… is important to our understanding of how allochthonous inputs to aquatic habitats drive biodiversity in wetlands. It also addresses a timely conservation concern in southeastern Louisiana where invasion by Chinese tallow trees (Triadica sebifera) is displacing native trees. The invasion …

Changes in litter inputs and decomposition in headwater streams during a mountain pine beetle infestation of whitebark pine
… lacking in primary productivity and rely on allochthonous inputs to fuel secondary production. This close association with the forested landscape makes these streams sensitive to terrestrial disturbances. In the Greater Yellowstone Ecosystem (GYE) a climate change induced mountain pine beetle …

Ammonia uptake by phytoplankton and limnological studies of Mountain Lake, Virginia
… became dominated by blue-green algae. When allochthonous inputs of inorganic nitrogen renewed the levels of ammonia-nitrogen, Vmax values increased and the community changed, replacing the blue-green algae. Communities dominated by green algae (Chlorophyta) had higher MeA (and thus ammonia) …

The Importance and Seasonal Variation of Terrestrial Invertebrates as Prey for Juvenile Salmonids on the Kol River Floodplain, Kamchatka, Russian Federation
… We examined terrestrial invertebrate inputs into spring brooks and their use as prey by salmonids in two spring brook habitats from May- October 2006 on the Kol River flood plain in Kamchatka, Russia. Benthic and drifting invertebrates, terrestrial invertebrate inputs, terrestrial …

Closing the knowledge gap surrounding nitrogen cycling in Minnesota lakes
… loss of biodiversity and harmful algal blooms. Allochthonous inputs are typically the critical drivers of eutrophication, but it is also important to understand how those inputs interact with internal processes to characterize future N scenarios. Microbial processes such as N fixation and …

Influences of land use on the structure and function of headwater streams: A multiple scale analysis
… streams. In some streams, increased sediment inputs as a result of agricultural activity or residential development in riparian corridors may limit the distribution of shredders and thus influence leaf breakdown rates. Alternatively, near stream development may reduce the quantity and/or …

Biotic Impacts in Shallow Water Bodies of South Dakota Resulting From Common Carp Invasion
… dominated watersheds may mean that allochthonous inputs are very influential in the dynamics of these water bodies and nutrient turnover rates may differ substantially among systems. Lastly, carp relative abundances may not have been high enough to induce some of the ecosystem …
