Effects of Enzyme Complex Supplementation to a Paddy-based Diet on Performance and Nutrient Digestibility of Meat-type Ducks
Autor: P. Kang, Y. Q. Hou, Derek Toms, N. D. Yan, B. Y. Ding, Joshua Gong
Publikováno v: Asian-Australasian Journal of Animal Sciences, Vol 26, Iss 2, Pp 253-259 (2013)
Paddy rice is rarely used as a feed because of its high fiber content. In this study, two experiments were conducted to study the effects of supplementing an enzyme complex consisting of xylanase, beta-glucanase and cellulase, to paddy-based diets on

Demographic and genetic evidence of the long-term recovery of (Daphnia galeata mendotae) (Crustacea: Daphniidae) in Sudbury lakes following additions of base: the role of metal toxicity
Autor: D J Taylor, H Lin, J M Filion, P G Welsh, N D Yan
Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 53:1328-1344
Twenty-year records of changes in abundance of Daphnia galeata mendotae are presented for Middle and Hannah lakes, two metal-contaminated lakes near Sudbury, Ontario, whose acidity was neutralized by additions of base in the midn1970s. A comparison o

Use of water clarity to monitor the effects of climate change and other stressors on oligotrophic lakes
Autor: J M, Gunn, E, Snucins, N D, Yan, M T, Arts
Publikováno v: Environmental monitoring and assessment. 67(1-2)
We present evidence from studies of lakes in Killarney Park, Ontario, Canada that water clarity is a key variable for monitoring the effects of climate change, high UV exposure and acidification. In small oligotrophic lakes, these stressors affect wa
