Revision as of 03:42, 19 November 2008

Removed the verify for livestock breeding without being in contact; I've personally witnessed a female camel and a female horse locked deep inside my fortress get telepathically impregnated by outside animals. unsigned comment by Drawfirons

Telepathically impregnated by wild outside animals? It's not part of the original question, but it sounds like that's what you're saying. --RomeoFalling 20:18, 8 November 2008 (EST)

I feel it should be mentioned somewhere that both hunting and livestock are non-renewable without some luck as to what animals are brought as pets with immigrants. Tame animals (those that are not pets) seem to be considered 'wild' in that they obey the limits set forth in the raw file for the number that will be 'spawned' (or born, if you will) before hitting a max. Basically, unnamed animals will eventually stop breeding, and only those pets with names will continue to breed. Hence why catsplosion is so bad, and why it doesn't happen with any other animals. Barring the ability to assign other animals to dwarves (and hence, give them names) I don't think meat is a very viable industry in the long term. --Gotthard 18:44, 9 November 2008 (EST)

I've seen one player claim that wild animals can be hunted to extinction. I haven't seen that myself. Barring that, hunting is renewable, albeit limited.--Maximus 21:06, 9 November 2008 (EST)
Are you saying there's a cap on live+deceased animals? If livestock doesn't need to cross paths in order to impregnate, then the meat industry is perfectly viable, although there may be some framerate issues if you choose to do more than one type of livestock -- just list one bull and eight cows as available for adoption. As for the extinction thing, are you sure he wasn't talking about the Cancel Hunt messages that say something like "There are no animals in the swamps" or somesuch? --RomeoFalling 23:09, 9 November 2008 (EST)
I have no idea what the "extinct animals" poster had experienced. I have my doubts about the claim, but can't rule out that it happened, at least to him.
There is a population cap on animals (per-species). It used to be 80, I believe, but it seems more like 50 these days. I haven't formally tested it, but my suspicion is that once you hit that population cap, breeding for that species ceases permanently, even if their count falls below the cap again. If that's true, then animal breeding is a finite resource, unless you cull their numbers carefully to keep them under the limit at all times.
I'm presently setting up a mega-corral, so I'll be testing it soon.--Maximus 23:57, 9 November 2008 (EST)
When I say renewable, I mean will never run out. Trees are renewable, given space to grow. Hunted animals are not. It isn't a *claim* that animals can be hunted to extinction, the numbers are in the raws for each particular animal. After that many of animals exist (living or dead I presume), no more are generated, whether through off-map activity, or being born as offspring. The same is true for livestock brought with you, or traded. The only animals that do NOT obey this limitation are pets (and perhaps named animals in general). I have had the same base for 15 years, and I haven't had any offspring from horses, dogs, or cows in about 9ish years. However, there are still animals being born, and I've traced the number per year back to the number of female pets I have. I'm not sure if named pets only mate with named pets, but a single female pet doesn't seem to yield any offspring (but this should be verified). I had about 20ish puppies per year at max, and it abruptly stopped. It has recently started up again, as puppies brought as pets have matured. Same thing for horses and cows, but it is slow. Frankly, with immigration stopping, and no way to assign pets (iirc?) my animal "home grown" animal supply will soon dry out. The same is not true of turtles, they seem to respawn, but I think fish fall into this category, my river hasn't had anything but turtles for 10ish years. --Gotthard 23:20, 9 November 2008 (EST)
Well, if you're referring to [POPULATION_NUMBER], Creature_tokens#P says that that is the minimum/maximum number that can show up on a map in the space of a year. I've killed something like 150 bonobos on my map, but they're still coming.
Tame animals, on the other hand, clearly have hard population limits (otherwise they'd breed into the thousands and turn every fortress into a "tribbles" episode). As I posted above, it appears that once that population limit is reached, breeding stops permanently (I'll have to test it further at some point). As far as I can tell, however, that limit does not apply to wildlife. It probably doesn't apply to wildlife even after you've hit the limit on tame animals of the same species. (It's been a while, but I once had a fort with a bunch of domesticated musk oxen. I think wild ones still showed up long after the tame ones stopped breeding.)--Maximus 02:23, 10 November 2008 (EST)
Do you know if this was changed recently? Best I can recall, EVERY fortress I've started has eventually killed off all non-aggressive wildlife. I'm not sure, but bonobos may be somehow classified as 'invaders' (aren't they the ones that steal everything?) so perhaps there are no limits on them. It takes me ~3 years to kill off all the wildlife on my map, and after that nothing else shows up. I took the numbers in the raw to be a global maximum in existence... I can verify tame animals stop breeding after a max is hit, and they do NOT start breeding again after the number goes below this. However, I'm fairly certain there is a max limit present for tame animals, as I went through cows pretty regularly, culling the population to keep it manageable. My money is on a global max ever, not alive at any one point, but I could be wrong. (Also, I think wild and tame ones are calculated separately... does your tone indicate they eventually stopped as well?)--Gotthard 22:08, 14 November 2008 (EST)
Bonobos are "wild animals" in my unit list, and they aren't one of the thieving species. I'm not sure whether all wildlife can be killed off; we need more people to chime in about their experiences. My bonobo death count is about 200 now, and shows no sign of stopping. (I've been using nerve-injured soldiers, not hunters, to do the killing.) However, I also finally have a breeding stock of tame bonobos, and I'll let them breed up to the max to see if affects their migrating onto the map. My bet is that the species cap is just for breeding, not migration.--Maximus 23:13, 14 November 2008 (EST)
I'm not doubting your experience, but I've had 4-5 maps where I consistently run out of deer. The species cap there seems to function fine, I *never* had any deer offspring, just hunted them for a while until they stopped (year 3-4ish). I can't verify wolves, however. So bonobos aren't predatory at all? I was thinking maybe more 'aggressive' animals (even if they're not thieves) may reproduce ad infitum. Or perhaps I scared them all off with my deer genocide? I mean anytime a deer showed up, I had 3 guys run down and punch it to death. Are you nicer to your bonobos? And have you seen that with any other animals? I've run out of hoary marmonts, mountain goats, and deer (on separate maps). Sorry to be insistent, but this seems like one area we don't have a lot of info. --Gotthard 22:42, 18 November 2008 (EST)
