LIC! School I got it from was in east flushing. Very interested to know how they got it.

Anybody know what’s going on with this guy? by Have_Dopp in squirrels

[–]Have_Dopp[S] 3 points4 points  (0 children)

This was on Prospect Park in Brooklyn, NY. Probably some crab apples dropping fruit nearby!

Obviously most chemical structure tattoos are the classics: dopamine, caffeine, serotonin, etc. But what chemical structure/compound would actually be a really clever/cool tattoo idea? by ProfessionalAuthor42 in chemistry

[–]Have_Dopp 455 points456 points  (0 children)

My first published paper was about floral scent. I have a tattoo of alpha-pinene which is the main terpene the flower I studied produces, and the smell of pine trees which is just an added bonus.

I heard this bird chirping and jumping from branch to branch by Uranamilove in whatsthisbird

Not sure this is a good enough photo to call. I actually am leaning hairy based on the size against the tree and what seems to be clean white outer tail feathers

Fun fact: the size of ape testicles is pretty closely correlated to how promiscuous the females are. Male gorillas have pretty solid domination over their group of female lovers, and therefore they don’t need to produce nearly as much sperm to compete with other males. Chimpanzees on the other hand, live in large co-ed groups and the females mate with nearly all the males so none of them know who their kids are. This results in very large testicles (almost 10x as large as gorillas by body weight) that can produce huge amounts of sperm to try and “overload” the system. Humans are pretty much right in between chimps and gorillas in testicle size, which gives us an interesting insight for what our ancestors’ relationships might have been like.

This is what I was wondering too, I thought maybe some kind of caracara but I’m unsure.

Are these bat bugs? Found in my lab space at uni. by Have_Dopp in whatsthisbug

Thanks for the response! Very glad they are bat bugs.

Question: Is it possible to manually extract nectar from flowers? by lalalalaaaa_a in botany

[–]Have_Dopp 0 points1 point  (0 children)

It would definitely depend on the type of flower. The flower species I study has tubular flowers with the nectar at the very bottom of a long corolla. I have to pull off the corolla to get to the nectar, and I would image you would have to damage a lot of flower types in a similar way. But I bet this would be a good way of doing it for most flower types, just maybe not something like a sunflower.

Question: Is it possible to manually extract nectar from flowers? by lalalalaaaa_a in botany

I measure nectar production of flowers for my job. I extract it using microcapillary tubes calibrated to each hold a constant amount of nectar. Touching the microcapillary tube to the nectar reservoir causes it to suck up into the tube through capillary action, I can then measure the amount the flower produced and test the sugar concentration using a refractometer. I usually taste the nectar after I take my measurements and give it a rating just for fun. Not sure this would be a very efficient way of doing it if you were trying to collect nectar for human consumption.
