Thanks to Rainforest Expeditions who organised our trip. www.rainforestexpeditions.com/
Full disclosure: we paid for our flights to Peru but Rainforest Expeditions provided our visit into the rainforest for free. We visited the Tambopata Research Center and the Refugio Amazonas lodges. If you'd like to visit via the method of exchanging money, check out their site or socials:

If you want to see more Amazon insects and animals it's worth checking out Mark's channel: www.youtube.com/@aFieldBiologist I also want to use a pinned comment to thank camera-person Alex and producer Nicole for trudging into the rainforest with me to make videos. One of them got peed on by a monkey.

You do realise that Mathematics is not a science?

@danielcasas9244 4 месяца назад

Mathematics is definitely a science in the sense of a systematic and formulated knowledge~proofs can be tested and found to be true, then one day an exception is found and the proof no longer valid-how is that any different than an experiment done in a lab needing repeated success to be considered valid?

I mean this is just completely needless, I've observed dozens of awesome rare species in shitty urban habitats with nothing but my eyes and a phone camera, and I've never hurt a single one If you wanna go crazy, get some blacklights or other bug-attracting lights and a white sheet (like what they do here). Or look up other ways to attract bugs. You will get way more than with pesticide, and bugs are much prettier alive and moving anyway. Also, to be clear, when you say "new species", you mean different species from the ones in other trees, right? Not new to science, surely, unless this guy is spraying trees in a remote New Guinean cloud forest. I saw over 100 species of animal and plant I'd never seen before in the span of a month or so last year, and I didn't kill a single one

@QuantumHistorian 4 месяца назад

This is nice, but I miss the old Stand-Up Maths who would have actually gone into the mathematics of the rarefaction curves and how that model is derived from the underlying assumptions. Cheerleading things that involve maths is nice, but I much prefer when Matt actually goes into the maths (recreational or academic). Sadly, that's becoming ever rarer... This video didn't include any more maths that it's title. The last one talked about an equation but didn't do anything mathematical with it. Before that there's a few about shapes being used in the architecture or decorations. I think "All Convex Polyhedra" from 6 months ago is the most recent video that actually does some maths, rather than talking about other people who did maths.

what is that moth wall?? is it some special material that moths love? or is it in a spot where there are so many moths, all you need is a flat wall for scooping them into a jar?

@FunkyKiwiVG 4 месяца назад

The moths are attracted to the light. So they put out a bright light and a white sheet that helps make it very visible. As they also show in the video, one can use pheromones (smell) to attract them. Different species have different preferences.

@BrandyBalloon 4 месяца назад

I thought moths fly in circles around a light not because they are attracted to it, but because they use the moon to navigate. The artificial light screws up their sense of direction i.e. they think they're flying in a straight line by keeping the light (usually the moon) in the same direction, but if the light is close then they just end up flying in circles. Perhaps the big white sheet confuses them, like a jamming signal, so they stop for a rest.

@BrandyBalloon 4 месяца назад

Just to add to that... I just realized that if a moth was trying to keep the light at an angle less than 90 degrees away from straight ahead, it would spiral in towards it. Conversely, if it was trying to keep the light at an angle greater than 90 degrees away from straight ahead, it would spiral away from it. So if all the moths were trying to fly a straight line in random directions, half of them would end up getting closer to the light, and the other half further away. Unless of course the light actually was the moon, in which case the distance is so great they'd be flying in a straight line.
