New methods, visualisations and R package
(github.com/andrew-edwards/si…) for fitting size spectra to
binned data. See our new @MEPS_IR paper
int-res.com/articles/meps_oa…. Thanks to awesome co-authors @jamespwr
@BlanchardJulia @baumlab @MichaelPlankNZ
Want to reduce perceived uncertainty by billions of fish? Try highest density intervals instead of equal-tailed intervals. Can also change perception of stock health.
New short paper with @AugerMethe

New paper where we dig into and explain the methods behind Empirical Dynamic Modelling, with a narrated movie and new R package.

Thanks @mariagrigoratou for organizing this, and especially for figuring out all the time zones 🤯
📢Join us for the grand finale of SPECTRE seminars after 3 amazing years!
@AndrewM_Edwards dives into fitting size spectra to ecological data with fish examples.
Catch it either on Nov 1 or Nov 2, 2023-two chances for different time zones! More info & registration links 👇(1/3)
How to account for the fish that would have been caught if they had taken the bait quicker? See our new method to deal with hook competition in longline surveys. Relative abundances can 1/2 or 2x from usual methods. With awesome Joe Watson and @augermethe cdnsciencepub.com/doi/10.113…
Great Nature piece about reproducible research. It's timely as we've just updated our "Building Skills in Quantitative Biology" e-book (to meet web accessibility standards), where you can learn some of the tools mentioned (and more). quantitative-biology.ca/ @ecotheory

Amazing acoustic rendition of Bowie's Space Oddity by 500+ people. Worth a watch on his (and Stephen Hawking's) birthday. youtu.be/cKg1_fKO1sY via @YouTube
Postdoc in salmon productivity here on beautiful Vancouver Island. Lots of modelling and R (and fieldwork opportunities):
Recruiting a salmon ecology #postdoc with @DFO_Pacific to explore sockeye survival across life stages. Modeling focused but fieldwork options!
2 yrs, $62-66k CAD/yr, Nanaimo BC. Apply by Dec 15.
Feel free to DM w/ questions. Please RT!

Thank you @GargulMark for creating a cartogram (each riding has the same area) of the Canadian election results #elexn44. Stops me complaining all night that the usual maps are misleading to the eye... commons.wikimedia.org/wiki/F…
Our COVID modelling paper is published. The model is used by British Columbia government and the Public Health Agency of Canada (e.g. today's bottom figure of cbc.ca/news/politics/phac-mo…).

Paper: journals.plos.org/ploscompbi… . Thanks to @MichaelPlankNZ & Audrey Lustig for fitting NZ data, & to great collaborators @sean_anderson @CarolineColijn @DanCoombsUBC @JEStockdale @rebs1707 @Iyaniwura_s @MikeAIrvine @naveedjanjua @MYerlanov Nicola Mulberry & Michael Otterstatter
Yes to L'Hopital answers. But in original problem isn't k an integer?
So can you really have limit k->0?
But set k=0 and you get -ln(lambda e^-lambda) which as lambda -> 0 is -ln(0) = -infinity. Hmmm.... I thought it might drop out to 0 (like you have) until I got to the end!
Working back to the origins of my problem, and assuming that 0^0 = 1 (as seems indisputable, Google pers. comm.), then I think:

I pledge to continue opposing racism and hate, including systemic racism in science. And to do this work everyday. Join me by nominating 5 others to do the same (thanks @AugerMethe). @IanJonsen @jamespwr @BlanchardJulia @MichaelPlankNZ @DrYool

Awesome job with the figures (and R code) @sean_anderson, and great to see the @globeandmail communicating the uncertainty.
@sean_anderson did so much of this, and the team- fitting multiple locations with various testing, spikes, etc.

Intense few weeks of modelling to quantify the impact of COVID-19 control measures in British Columbia - preprint now at medrxiv.org/content/10.1101/… . Great team including @sean_anderson @CarolineColijn @DanCoombsUBC @rebs1707 @Iyaniwura_s and more.
Finally screened! medrxiv.org/content/10.1101/…. . We estimate strong impact of distancing measures in BC 1/

Very sad to hear this. Trevor had a huge influence on me, bringing me to Canada for a postdoc and encouraging me to stay. He influenced many careers and had a deep understanding of numerous diverse scientific areas. A true giant. Condolences to Shubha at this time.
PML is very saddened to report the passing of Professor Trevor Platt FRS, following a short illness. He will be much missed by all at PML & the wider science community, leaving a legacy that will continue to influence for a better & more equitable world. bit.ly/2RlbHTk

If you want to understand some of the modelling being done on COVID-19 I highly recommend this talk by UBC math biologist @DanCoombsUBC. (Thanks @ruth_baker for originally mentioning it). youtube.com/watch?v=dLVLEZMz… #FlattenTheCurve
