I think with this particular study, the nbmuers were so low that it was easy to count every individual. However, the means of counting vary from study to study. In one damselfly study I did as an undergrad, I marked off a particular area of the shore of a pond where I was observing damselfly behavior and counted every flight I observed within that area as part of my study. Others will do mark-recapture studies to estimate total nbmuers and others will use other methods of estimation. Sometimes you can't count them all and you have to rely on estimations, but so long as you explicitly state in the methods how you counted, then people will be able to understand what you did well enough to make their own conclusions based on your data. And thanks for the idea for a post! It's not one I'm going to do right away, but it would be a good topic to mull over for a while. And yes, I'm going to do more of these posts in the future. I normally do more of them than I have the last several months, so I want to get back into them.
I've found breaking the gpuros up as follows to be helpful. Group 1 True Camponotus and Tanaemyrmex. These are all on the larger side of the spectrum. Size ranges from 6mm to 20mm long.Group 2 Myrmentoma, Myrmobrachys, Myrmothorix, and Myrmosphincta. These are basically smaller version of Group 1. Often the largest majors are only 7mm long, or certainly less than 10mm long. Group 3 Colobopsis and Myrmaphaenus. I call these door ants because the queen and largest majors all have flattened heads which are used like doors. These are small as in Group 2.
I almost alayws find watching documentaries a frustrating experience, for just that reason. If the documentary is about something you don't already know everything about, then you often don't have the basis to judge the information critically, and can't really tell if and when the truth is getting short shrift.(It's a different experience when I'm watching a documentary about something I already understand. But then I'm not really watching to learn something new; I'm just watching in order to form an opinion about the documentary. Which can be fun, of course, but it's not the same kind of fun as being educated.)The thing is, I don't really understand why this has to be the case. In principle, watching a documentary shouldn't be any more (or less) exasperating than reading a book on a subject. But something about the medium whether due to an intrinsic factor (maybe the limited time available) or historical accident seems to make documentaries much less worthy of my trust.
I give birth to be familiar with a few of the arclties on your website trendy, and I really like your tastefulness of blogging.

Pas pratique, e0 mon avis.. par rapport e0 la simplicite9 d'un blog comme Overblog, que j'ai choisi au final, et surtout gratuit..Je viens de faire un tour sur des galeries Piwigo et c'est vrai que vos pre9sentations sont tre8s belles et mettent bien en valeur les photos, mais l'administration est elle simplifie9e sur le blog ?Par ailleurs, y aura t-il une version gratuite ?Merci de votre re9ponse
How does one correlate dnhacroious glacial strata?That's a bit beyond the scope of this post, don't you think? And you should note that I was quite conservative in my description. There are lots of apparently glacial deposits around the world which roughly fall into the period between 750 and 635 million years. The oldest one in this region has a maximum age of 750 million (from dating of a granite cobble within it, if I recall correctly).The late Neoproterozoic wall clearly a time where the world was quite glaciated. Whether you can correlate everything into two global events is another question entirely. And what might be the survival of recognisable eukaryotic groups though this period is not what you might expect if there was a total deep freeze.
I not to mention my friends were actually reading through the good secrets found on your site while all of a sudden came up with a horrible feeling I never thanked the website owner for them. Those people ended up so very interested to read them and already have honestly been taking pleasure in these things. Thanks for simply being so thoughtful as well as for making a decision on these kinds of wonderful issues most people are really desperate to understand about. Our own sincere regret for not expressing gratitude to you sooner.
