Anyone can advise where to find data on body mass/length of common marine zooplankton species (e.g. crustaceans)?

What test should I use to compare two or three means, if data is not normally distributed but sample size is > 30 in each group?

I personally feel this as a most confusing question. As per my understanding, if sample size is > 30, and sample is skewed, we can still use paramteric approach, as it will follow Z...

How to handle studies which report perfect effect sizes in a meta-analysis using Pearson's r?

I'm in the process of updating a meta-analysis and in one of the new studies, effect sizes are reported as Tau-U. Two of the effect sizes are reported as Tau-U = 1.00. I am using Andy Field's...

Привет, товарищ Потапов! It may be helpful for you to contact Dr. Steffen Harzsch (steffen.harzsch(at)uni-greifswald(dot)de). Members of his AG are working on crustacean zooplankton at both Greifswald and Helgoland. Warm regards from Washington DC!

Anton Potapov

Привет, товарищ Карлос)

Thanks a lot for this suggestion, I'll write him. Greetings from me and other comarades here.

Hi!

For copepods you may want to look at Benedetti et al. 2015 sup table 1. In case you don't already have this reference...

Best,

Dear Nicolas,

Thanks a lot for your answer! This is indeed very nice data. I have found some of species I need there.

Probably, it's worth looking into some identification keys, but I don't have an idea, which one can be good. I guess I have mostly arctic species.

Hi again.

For taxonomic key i know this one from David Conway for zooplankton of the english channel (Plymouth Marine Fauna) that you might found usefull:

Part1:Technical Report Marine zooplankton of southern Britain. Part 1: Radiolaria, ...

Part 2:Technical Report Conway, D.V.P. (2012). Marine zooplankton of southern Britai...

And Part 3:Technical Report Conway, D.V.P. (2015). Marine zooplankton of southern Britai...

Moreover for copepods you can browse this website:

http://copepodes.obs-banyuls.fr/en/

You will probably find a lot of information in there but it might be a long work to gather it in a way you can use

Hi Nicolas,

Thanks a lot for your helpful and fast response. I get also some information from this keys. Great!

Dear Anton!

There are two references on weights of copepods

- Канаева И.П. Средний вес Copepoda Центральной и Северной Атлантики, Норвежского и Гренландского морей // Тр. ВНИРО. 1962. Т. 46. С. 253-266.

-Перцова Н.М. Средние веса и размеры массовых видов зоопланктона Белого моря // Океанология. 1967. Т. 7. № 2. С. 309-313.

Its are in Russian, but I think it is nor the problem for you.

Уважаемый Андрей,

Спасибо большое за ссылки! Нашел полезную информацию.

There's also Mauchline's book Biology of calanoid copepods, 1988, Academic Press with a nice review of published regressions for dry, carbon and nitrogen weight vs. body length for many species

Dear Danilo,

Thanks a lot. It's closely related topic. I also found some publications on regressions. If it's of interest, there are some more recent examples:

Nakamura et al. 2017 "Length-weight Relationships and Chemical Composition of the Dominant Mesozooplankton Taxa/species in the Subarctic Pacific, with Special Reference to the Effect of Lipid Accumulation in Copepoda"

Robinson et al. 2010 "Length–weight relationships of 216 North Sea benthic invertebrates and fish"
