SIA for larval fish? Not like juveniles

Stable isotopes analysis (SIA) for larval fish? Maybe NOT like juvenile fish! CitationWeiping Mei, Yu Umezawa, Xin Wan, Jinghan Yuan, Chiyuki Sassa. (2018) Feeding habits estimated from weight-related isotope variations of mesopelagic fish larvae in the Kuroshio waters of the northeastern East China Sea. ICES Journal of Marine Science, fsy016, https://doi.org/10.1093/icesjms/fsy016 Highlights1. The nitrogen isotope of fish in the pre-flexion stage could NOT be used for trophic position analysis because the maternal effect (i.e., the residual isotopes in larval fish from their parent fish individuals). 2. The nitrogen isotope of fish after flexion stage could be appropriately used for trophic position analysis because the maternal effect was shown to disappear. 3. The isotopes of fish in the larval stage changed with their body weight (or body size), and we hyphthesised that the trends (of isotopes vs body-weight or body-size, Figure S1)are different based on their different breeder types (income breeder and capital breeder) of their parent fish species.

How to run y=a+b*exp(c*x) in R

Fomula as y=a+ b*e(c*x) For exampleto get the turnover time for stable isotopes: δt = δf + (δi - δf)evt See caution part and original R codes: http://blog.sciencenet.cn/blog-651374-1014133.html

Hexo test bilingual

I am truly thank the share link of [chenymr’s website] for his introductions about how to built a bilingual website based on Hexo. The detials please find in his origianl post written in Chinese, here, I just want to highlight something from that post.

Run ANCOVA correctly in R software

Briefly, covariance analysis (ANCOVA) is expressed in the R language as y ~ x +/* y0, where the variable is y, the covariate is y0, the independent variable is x. Then, go ahead code test.
