“…The biota inhabiting aquatic ecosystems are a function of the nature of the physical and chemical characteristics of these ecosystems, thus providing a direct, holistic and integrated measure of the integrity of the ecosystems (Linstead et al 2012). Therefore, the ultimate monitor of the aquatic ecosystem is the aquatic life itself (Brabets and Ourso 2013).…”

Zooplankton play an important role in the faunal biodiversity of aquatic ecosystems as they assist in transferring algal energy to higher trophic levels through grazing and also eliminate harmful algae from water. The zooplankton and environmental characteristics of Yardantsi Reservoir were studied in order to provide essential information on this important ecosystem that serves as domestic and irrigation water supply, and fishing ground. Samples for water quality and zooplankton analyses were collected from the reservoir from May, 2015 to April, 2017 using standard methods. Three groups of zooplankton (Copepoda, Cladocera and Rotifera) comprising of thirteen genera were encountered. Rotifera (36.69%) and Cladocera (34.44%) were numerically dominant during the rainy and dry seasons, respectively. The highest zooplankton abundance (5646), species richness (11), Shannon-Weiner index (2.25) and Margalef's index (1.16) were observed during the rainy season. Axes 1 and 2 of the principal component analysis (PCA) explained 74.82% and 11.89% of the zooplankton-environmental variable relationship. Diaphanosoma sp, Eubranchipus sp, Kellicottia sp and Macrothrix sp were mostly influenced by NO3, BOD, depth, pH and dissolved oxygen while Cyclops sp and Daphnia were mostly influenced by changes in alkalinity, hardness and chloride. Brachionus patulus, the dominant species in the reservoir was mostly influenced by PO4-P. The study shows that the reservoir is slightly polluted and it is essential to adopt effective management strategies such as reduced agricultural run-offs and riparian animal grazing to prevent further deterioration of water quality.

“…In Denali National Park and Preserve (NP&P) alone, there were 35 active mining operations underway when a court-ordered injunction ceased most activity in 1985. A recently completed assessment of mining reclamation at Kantishna Hills in Denali NP&P in Alaska shows how research on the effectiveness of specific management strategies was used to improve water quality (Brabets and Ourso, 2013).…”

BackgroundThe U.S. Geological Survey (USGS) and the National Park Service (NPS) work together through the USGS-NPS WaterQuality Partnership to support a broad range of policy and management needs related to high-priority water-quality issues in national parks. The program was initiated in 1998 as part of the Clean Water Action Plan, a Presidential initiative to commemorate the 25th anniversary of the Clean Water Act. Partnership projects are developed jointly by the USGS and the NPS. Studies are conducted by the USGS and findings are used by the NPS to guide policy and management actions aimed at protecting and improving water quality.The National Park Service manages many of our Nation's most highly valued aquatic systems across the country, including portions of the Great Lakes, ocean and coastal zones, historic canals, reservoirs, large rivers, high-elevation lakes and streams, geysers, springs, and wetlands. So far, the Water-Quality Partnership has undertaken 217 projects in 119 national parks. In each project, USGS studies and assessments (http://water.usgs. gov/nps_partnership/pubs.php) have supported science-based management by the NPS to protect and improve water quality in

The current study results from the collection of Chironomidae, which began in 1994 and continued until the present time in six biogeographical regions of Alaska, USA. We established that 427 species are currently reported from Alaska, adding 154 new faunistic records and six new species. In this study, we described Chaetocladius (Chaetocladius) kimfrangosi sp. nov., Chaetocladius (Chaetocladius) mendenhallensis sp. nov., Chaetocladius (Chaetocladius) tonitrus sp. nov., Corynoneura palus sp. nov., Stilocladius keithsomersi sp. nov., and Paratanytarsus giminilacus sp. nov.. Additionally, we describe the larva of a pupa Roback (1971) thought likely to belong to Krenopelopia narda Roback, 1971, the female of Cricotopus (Paratrichocladius) scaturigineus (Makarchenko & Makarchenko, 2014), and the female and pupa of Heleniella parva Sæther, 1985. For the first time, we provided a checklist of Chironomidae with distributional records from Alaska.
