    I didn’t mow my lawn like planned this weekend because a bunch of violets and dandelions and other flowers popped up, and the bees were having a great weekend because of it.

    Bonus points : The Scott’s Lawn truck came through and they didn’t even bother leaving a flyer on my door.




  • They can if they do too many dives in rapid succession.

    You get the bends by having a lot of nitrogen dissolved on your bloodstream due to the pressure. So it’s a function of how much nitrogen you breathe, how much pressure you’re breathing it at, and the total amount of blood (and some other tissues) in your body that can absorb that nitrogen. Divers get the bends because they are taking multiple breaths of air under pressure, there is multiple lung volumes of nitrogen cycling though the diver. Whales and other diving animals don’t typically “hold” their breath when they dive, but if they did, it would only be 1 breath of air for the entire dive. Air in the lungs is bouyancy they don’t want and can potentially injure them when it re-expands. Most marine diving animals will saturate their blood and muscles with oxygen at the surface and then dive and exhale.

    Great Smoky Mountains National Park has a “Lightning Bug Lottery” every year, a certain number of passes are randomly given out to applicants to see the park at night during peak breeding season for fireflies. Supposedly they will all sync up their lights and converge in a huge group on one tree.

    I’ve seen a smaller event once in my hometown. Just a whole tree was sparkling for a few minutes. I think the most amazing thing about it is the light doesn’t really show up well on a camera, so you kinda have to just put your phone down and enjoy it with your eyes. The only place you can keep that moment is in your mind.


  • Nope. Evolution doesn’t really work like that. A ‘successful’ organism simply needs to have offspring capable of producing more offspring. In the case of a parasite, it just needs to keep the host alive long enough to infect another host. Anything more than that and you start running into quality vs quantity issues. A longer living, self limiting parasite isn’t going to reproduce as fast (as size longevity goes up, reproductive rates generally go down)

    A fast acting, highly transmissible parasite is generally going to outcompete slower parasites.

    You should try reading your source…

    “Experts say the American alligator’s top running speed clocks in at 11mph.”

    I a fat outta shape slouch, but I think in a life or death situation I could manage 11mph for a few minutes.

    Sure they can burst a good bit of speed, but that 20-30 ft sprint mostly comes from them lunging with all 4 legs and their tail as hard as they can and then maybe 1 or 2 more lunges and some scrabbling.

    It’s mainly a matter of weight and gait. They got stubby little side protruding legs and they weight a ton incomparison to their leg musculature. They can high walk for a good distance, and they can gallop, but only for a few steps.
