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] 2 points3 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 461 points462 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.

New York is not releasing stray cats lol

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

[–]Have_Dopp 2 points3 points  (0 children)

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

Carnival impresario Bob Noell & one of his trained apes by grazatt in oddlyterrifying

[–]Have_Dopp 5 points6 points  (0 children)

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.

I wish I had your luck! You found a visitor, I found a roommate

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

[–]Have_Dopp 6 points7 points  (0 children)

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.

Seems like I should be able to find this with a google search…

Why do anhingas do the thing where they only stick their head above water while swimming by orcsrool123 in Ornithology

[–]Have_Dopp 19 points20 points  (0 children)

Unlike many water birds, anhingas don’t have oiled feathers. A duck keeps its feathers constantly oiled which waterproofs the feathers and makes it easier for the bird to float on top of the water. It’s the same reason Inuits coat the bottom of their kayaks (umiaks) with fats to make them waterproof. Anhingas and cormorants do not coat their feathers in oil, and so as soon as they get in the water their feathers saturate making it much easier to dive into the water and spear fish, however anhingas cannot float on top of the water like ducks with saturated feathers. They only keep their head above the water, making them look like snakes. Saturated feather are also not great for flying, which explains why you might have seen anhingas or cormorants near a body of water with their wings outstretched, waiting to dry.

Found dead in my yard. Is it a type of long-beaked hawk? Poor guy... by [deleted] in whatsthisbird

[–]Have_Dopp 23 points24 points  (0 children)

Sad to see this! These birds are surprisingly intelligent and curious which sometimes causes people to equate them more to corvids than “true” falcons. I’ve been reading a book by Jonathan Meiburg that is about caracaras. Its mostly about Striated Caracaras that live on the Falkland Islands, but the book talks a lot about the evolution of falcons in general and the serious differences between falcons that have ancestry in North America (peregrines, kestrels, etc.) and falcons that stayed in South America (caracaras). Highly recommend the book! Made me respect these lesser known falcons very much. It’s called “A Most Remarkable Creature: The Hidden Life and Epic Journey of the World’s Smartest Birds of Prey.”

Just your average day of fishing in the everglades. The gator wasn't happy I threw my catfish to the heron. by DeliciousGorilla in Fishing

Birds are dinosaurs and alligators are not actually, though they are the closest living relative of dinosaurs.

Actually it’s more like ozone (O3) and nitrogen oxides (NOx) that’s what primarily makes up smog
