Seeing the landscape for the trees: Metrics to guide riparian shade management in river catchments
-
Rising water temperature (Tw) due to anthropogenic climate change may have serious conse- quences for river ecosystems. Conservation and/or expansion of riparian shade could counter warming and buy time for ecosystems to adapt. However, sensitivity of river reaches to direct solar radiation is highly het- erogeneous in space and time, so benefits of shading are also expected to be site specific. We use a network of high-resolution temperature measurements from two upland rivers in the UK, in conjunction with topo- graphic shade modeling, to assess the relative significance of landscape and riparian shade to the thermal behavior of river reaches. Trees occupy 7% of the study catchments (comparable with the UK national aver- age) yet shade covers 52% of the area and is concentrated along river corridors. Riparian shade is most ben- eficial for managing Tw at distances 5–20 km downstream from the source of the rivers where discharge is modest, flow is dominated by near-surface hydrological pathways, there is a wide floodplain with little land- scape shade, and where cumulative solar exposure times are sufficient to affect Tw. For the rivers studied, we find that approximately 0.5 km of complete shade is necessary to off-set Tw by 18C during July (the month with peak Tw) at a headwater site; whereas 1.1 km of shade is required 25 km downstream. Further research is needed to assess the integrated effect of future changes in air temperature, sunshine duration, direct solar radiation, and downward diffuse radiation on Tw to help tree planting schemes achieve

Sour Streams in Appalachia: Mapping Nature’s Buffer Against Sulfur Deposition
-
Sulfur emissions are regulated by the Environmental Protection Agency, but sulfuric acid that has
leached into soil and streams can linger in the environment and harm vegetation and aquatic life. Some
watersheds are better able to buffer streams against acidification than others; scientists learned why in
southern Appalachia.

Southeast Aquatic Barrier Prioritization Tool
-
The Southeast Aquatic Barrier Prioritization Tool aims to build aquatic connectivity in rivers and streams. The Tool provides inventory data on aquatic barriers (like dams and road-related culverts) and helps practitioners to describe, understand, and prioritize these barriers for removal, restoration, and mitigation.
Aquatic connectivity in rivers and streams is essential for fish and other aquatic organisms.
The Southeast Aquatic Resources Partnership (SARP) developed the tool with support from partners and funders.

Three new darter species of the Etheostoma percnurum species complex (Percidae, subgenus Catonotus) from the Tennessee and Cumberland River Drainages
-
The federally endangered Duskytail Darter, Etheostoma percnurum Jenkins, is known from only six highly disjunct populations in the Tennessee and Cumberland river drainages of Kentucky, Tennessee, and Virginia. Only four are extant. Variation in morphology including meristics, morphometrics, and pigmentation was examined among the four extant populations and limited specimens from the two extirpated populations (Abrams Creek and South Fork Holston River). Analyses of these data found each of the extant populations is morphologically diagnosable. The few specimens avail- able from Abrams Creek and South Fork Holston River prevented thorough assessment of variation, and these were grouped with their closest geographic counterparts, Citico Creek, and Little River, respectively. Three new morphologi- cally diagnosable species are described: E. sitikuense, the Citico Darter, from Citico Creek, Abrams Creek, and Tellico River (Tennessee River system); E. marmorpinnum, the Marbled Darter, from the Little River and South Fork Holston River (Tennessee River system); and E. lemniscatum, the Tuxedo Darter, from the Big South Fork (Cumberland River system). Each species warrants federal protection as an endangered species.

Watershed-Based Approach to Channel Stabilization and Sediment Control in Pleasant Run Creek
-
Excessive sediment from channelized tributaries of the Hatchie River (TN) are degrading downstream aquatic habitat. Pleasant Run Creek is a channelized tributary to the Hatchie River, exhibiting significant soil erosion and channel incision problems. This project seeks to implement channel stabilization measures on private lands that will improve riparian habitat on Pleasant Run Creek and reduce sediment loading to the Hatchie River.
