Like, how long is the dwarf gestation period anyway? Would it be comparable to humans? It seems the women folk are pumping out babies like little factories. How can I teach my dwarves about population control?
Once married, they'll give birth about once a year. Short of killing them, there's not much you can do to stop this.
How does one get his hunters to clean up all their used crossbow bolts? My landscape is littered with them, and I want to instil in them the value of not littering.
You can't.
At best, you could pave over the tiles with a road or something to cover up the broken bolts.
What's the best way to tell my mayor she needs to chill out? She's asked for nickel items 3 times now, but I still haven't found any. I don't want to hurt her feelings, but I'll hammer her if I have too!
Little-known feature: You can manually select a different dwarf to be mayor. They might elect the old one back at the next election, so you could end up having to do this every year. Alternately, ask your liaison to bring nickel bars and garnerite boulders next year.
My dwarves seem pretty reckless. One built himself into a wall and died of dehydration. I love his dedication to his job, but he really didn't need to die for a simple interior wall. How can I teach them every life is precious, and that suicide is never the answer?
Dwarves building walls will always build them from the west if possible. If not he west, they'll build from the north, and if not that, east or south. They do this without consideration that they might be walling themselves up in the process. To force a dwarf not to stand in a specific spot when building, designate a wall on the spot you don't want them to build from, then suspend the construction of that spot. Dwarves won't stand on a spot where a wall is designated for construction while building.
