If you’d look at the title, you’ll see the one thing I want more than anything in the world but can never get because I’m a lonely loser: SSSSSSSSSSSSLEEP. (gotcha)
Foraging is the search/hunt for food amongst animals. Different animals take into account different factors when they forage, for example the bluegill sunfish classifies their prey into small, medium, and larger sizes. If the target is small (of low density), then it would eat a lot of that size, if only to gain enough energy/food. If the target is of high density, it would select a larger size, to get the most energy through one individual. If the prey is of medium density, it would choose large prey over small prey.
Another word for us is courtship, which is a complex interplay of two sets of communications. Courtship is how potential mates inform each other and read each other’s signals to know whether or not they’ll mate. Courting stimuli is normally specific to a species, allowing individuals to breed only within its own species. Factors that therefore affect courtship include: health, size, aggressiveness, resources, adaptive abilities, and parental investment.
Hey, that sounds like human.
DBQ page 355:
1) The flight lengths are shorter in autumn, measuring between 1-2 hours. Before sunrise, there is little to no activity and most flights happen before sunset. All flights end by 2100.
- a) During the summer there are many flights per day compared to during the autumn, when there is only one flight per day. However in both summer and autumn, all flights seem to start after sunset and end before sunrise.
- b) There might be a difference in behaviour because the environment changes with the season, making foraging harder during the autumn, which is why more flights happen during the summer and less happen during the autumn simply because there isn’t enough food. Also, summer could be mating season, huehuehue.
3) The bats are an example of rhythmical variation because they are nocturnal, meaning they forage at night and sleep in the mornings (aka my life). That’s daily; annually, more activity happens during the summer compared to in the autumn, when things calm down for the bats and they only fly once a day.
