Rationale Stable isotope analysis (SIA) is a powerful tool for examining diet and food‐web dynamics. SIA assumes “you are what you eat” relative to carbon (C) nitrogen (N). However, fractionation of during lipid synthesis violates this assumption; high‐lipid tissues do not reflect δ 13 C values therefore have the potential skew mixing model results interpretations, making corrections necessary. Methods Brook Trout ( Salvelinus fontinalis ) white muscle liver samples from several fish species...
Harmful Cyanobacterial Blooms (HCBs) threaten ecological and human health, their incidence magnitude appear to be rising globally. However, a lack of guidance exists on how choose the best HCB control mitigation strategy for different types water bodies. The portfolio available in situ techniques is diverse, ranging from experimental well established, with complicated poorly-documented records effectiveness across settings range unintended consequences. We introduce decision tree that...
Stable isotope analysis (SIA) is a powerful tool for assessing food webs and diet. However, the underlying assumptions that stable ratios in an organism's tissues reflect of its present diet may be complicated by isotopic turnover retention time. Quantification situ study organisms different via field studies essential to inform scientifically sound web utilizing SIA. Rainbow Trout white muscle liver tissue were collected monthly from North Twin Lake, Washington during 2013 growing season....
Line-diffuser hypolimnetic oxygenation (HO) was initiated in North Twin Lake, Washington, 2009 to mitigate loss of coldwater fishery habitat due temperature–dissolved oxygen “habitat squeeze” and reduce internal phosphorus cycling. Active tracking, net-captures, hydroacoustic analyses demonstrated that trout populations rapidly expanded into increased within the first few years oxygenation; however, long-term benefits many basic ecological aspects HO have yet be established. Diet food web...
Summer temperature/dissolved oxygen squeeze conditions have negatively impacted coldwater fisheries, including rainbow (Oncorhynchus mykiss) and brook trout (Salvelinus fontinalis), in North South Twin lakes of northeastern Washington. In 2009, line diffuser hypolimnetic oxygenation (HO) was initiated to prevent anoxia increase summer habitat. Suitable habitat volume increased from a low 0% preoxygenation 100% the hypolimnion following HO. To assess if utilized expanded oxygenation,...
