Dissolved inorganic carbon sourcing using δ13CDIC from a karst influenced river system
Rivers, representing the primary conduits of dissolved inorganic carbon (DIC) from the continents to the oceans, are important components to the global carbon cycle. To better understand the complex
Debris Dam Dynamics and Coarse Particulate Organic Matter Retention in an Appalachian Mountain Stream
Seasonal differences in retention potential were evaluated using 3-h releases conducted during winter, summer, and autumn, and it was implied that migration over time occurred by a simple mechanism of leaves falling off rocks and settling into debris dams.

Forested headwater systems provide critical habitat needs for diverse macroinvertebrate faunas globally. This study compared macroinvertebrate community structure between ten temporary and perennial
Linkages between riparian forest composition and shredder voltinism
The study stream appears to be an appropriate system for analyzing the riparian-shredder link because (1) the riparians assemblage is diverse within a broad range of leaf-processing rates, and (2) the shredder guild is correspondingly diverse with a wide array of seasonal growth patterns.
Environmental factors affecting the distribution of aquatic invertebrates in temporary ponds in Mammoth Cave National Park, Kentucky, USA
Despite a recent surge of interest in temporary lentic systems, a strong theory linking the biota to its environment has not emerged. Using data from 10 temporary ponds at Mammoth Cave National Park,
Updates to the stonefly fauna of Illinois and Indiana
In a first phase for reconstructing the stonefly fauna of the Midwest (Ohio, Indiana, Illinois, southern Ontario, Michigan, and Wisconsin) we present updates for the Illinois and Indiana stonefly
Processing and Macroinvertebrate Colonization of Black Cherry (Prunus serotina) Leaves in Two Streams Differing in Summer Biota, Thermal Regime and Riparian Vegetation
The results suggest that gathering-collectors may compensate for the reduced abundance of shredding detritivores in processing of summer leaf detritus and the absence of slow-processed riparian foliage in small woodland streams may prevent the establishment of a spring-summer shredder fauna.
The influence of flow impoundment and river regulation on the distribution of riverine macroinvertebrates at Mammoth Cave National Park, Kentucky, U.S.A.
The effects of impoundment by a low-head dam and hypolimnetic release from a reservoir on benthic macroinvertebrate assemblages were studied in two lowland rivers. The first river (Green River) was
Algal biomass accrual in relation to nutrient availability and limitation along a longitudinal gradient of a karst riverine system
Nutrient availability influences growth, productivity, and community structure of primary producers. Nutrient limitation, however, results from a deficiency mainly in nitrogen (N) or phosphorus (P)
Ohio USA stoneflies (Insecta, Plecoptera): species richness estimation, distribution of functional niche traits, drainage affiliations, and relationships to other states
The Ohio assemblage of Ohio stoneflies was assessed from over 4,000 records accumulated from 18 institutions, new collections, and trusted literature sources, finding that many rare species and several high quality stream reaches should be considered for greater protection.
