Interspecies Conflict/Tiger & humans
Let's say we have a large habitat with plenty of water prey & 4 changing seasons ( rainy in spring , Hot in summer , moderate in fall , cold & snowy in winter ) with the following animals
Siberian tigers (males in this territory often reach sizes of (660lbs) due to large amounts of prey available
Human (Stone Age) weapons bow& arrow spears clubs & fire
Jeffersons ground sloth
Songhua river Mammoth
Also the humans & Siberian tigers share a symbiotic relationship so tigers are often seen around human settlements, & a tiger will often help the humans hunt & protect their camp . Female tigers will often leave their Cubs with the females of the human tribe to to watch while the tigress goes hunting with the humans
Who will dominate the park , also which predator will be dominant in each season & how would the interactions be between every living thing in the park
Humans & Siberian tigers: The humans will be near the top of the hierarchy as long as they have a safe area (like a cave or protected structure) to retreat to. With the assistance of the Siberian tigers, they will be able to attain many food sources they need and defend their territory from many outside threats. Use of arrows will be very important to deter threats before they get close enough to invade the camp area. The amount of tigers the humans have will be of some importance, as some of the animals that might invade can defeat a Siberian tiger one-on-one. With the right strategy, any animal can be taken by the humans.
Siberian tiger: Will be the most dominant pure predator in the park, but may have trouble with animal groups if it's alone. Daeodon will be 3 times heavier and more than a match for it, but a tandem or a trio of these big cats will have a chance to overpower one (especially with human backup). The tiger will weigh 4 times more than a dire wolf, but any ratio of 5-to-1 favoring the wolves will be too much of a battle for the tiger or tigers. Arctodus will be able to drive a couple of Siberian tigers away, but 3 or more of the striped cats will likely be enough to overcome it. The Utahraptor will be too dangerous for a single tiger to tackle (it weighs 2/3 more than the tiger and is well-armed), but 2 will have a decent chance. Still, it will be a dangerous encounter, and it would be better to have the humans attack it first to weaken it before the tigers move in. A single Siberian tiger will weigh 4 times more than a Deinonychus, but the powerful cat can kill one quite easily, so it should be able to hold its own against 4 or 5 of them. If the human settlement only has one tiger that actually goes out on hunts, the humans will need to make sure the cat doesn't try to take on too much without their help. The animals that the tiger can overcome one-on-one are in groups. A single Siberian tiger can hunt moose, but ambush may be needed as a bull moose can potentially repel a tiger it meets face-to-face. 2 Siberian tigers will be needed to have a chance at the gaur, and the humans may need to assist. The Styracosaurus will weigh 9 times more than the male Siberian tiger, and will be out of its league. Without human help, the tigers will need to ignore this horned dinosaur. The Jefferson's ground sloth (Megalonyx) will be slow enough to be caught, but a single tiger won't be large enough to overpower it and the tough hide of the ground sloth will be hard to breach without great effort. The bison will be about as formidable as the gaur, and 2 Siberian tigers will be needed for any chance of a successful kill. Elk can be taken by a single tiger. The Songhua river mammoth (now known to be a Steppe mammoth) will be entirely too large for the tigers to overpower. Without human help, it will be off the menu. This mammoth was originally believed to weigh close to 19 tons or more (15 tons is a closer figure for the largest Steppe mammoths), which is over 50 times the weight of a tiger. With other animals available, it won't make sense for this animal to be targeted. Imagine the humans and tigers going out and actually killing one. Getting it back to the safety of the camp while defending it from attack (especially from wolves and dromaeosaurids) will be a monumental and risky undertaking. The woolly rhino will be just about as formidable as the Styracosaurus, so it will need to be ignored by the tigers.
Daeodon: This giant pig will be the size of a bison, and its huge head is armed with enormous bone-crushing jaws. Likely a scavenger first, it will be a danger to any other type of animal in its weight range or less. A good target for the humans or tigers if it comes close to the camp (will feed everyone), but can be a peril to them if they venture out. Can be overtaken by a pack of dire wolves (at least 6 or 7 will be needed for consistent success) or a group of Deinonychuses (many will be needed as well). A single Utahraptor may attack a single Daeodon, but the giant pig will be able to defend itself most of the time. 2 Utahraptors will have a great chance of killing it. The Arctodus will be close to the Daeodon's weight and will be a fantastic matchup for it (in most cases the pig will drive the bear away, but the bear is capable of getting a kill). Daeodon probably won't be the type of carnivore that chases prey like moose or elk, but it wouldn't be wise for a moose or an elk to stand close to it. Daeodon is capable of dominating any encounter with a moose or an elk, and might actually get the better of a bison or a Megalonyx in a turf battle (although a victory won't be guaranteed with these similar-sized animals). The gaur will be too large and powerful for the Daeodon to intimidate, and the Styracosaurus, mammoth, and rhino will be avoided altogether by the giant pig.
Dire wolves: These animals may be the most dominant predatory entity in the park, but their population will be a deciding factor there. For example, a dire wolf is a very close matchup for a Deinonychus one-on-one, but any encounter between these groups will depend on numbers. Arctodus will weigh over 12 times as much as a dire wolf, and their relationship will also depend on numbers. It will be similar to a pack of grey wolves dealing with a Kodiak or polar bear; 7 or 8 may be needed to intimidate the huge ursid and drive it off a kill. Utahraptor will be a tall task for a dire wolf pack (this theropod can easily inflict mortal wounds on a dire wolf), but enough of them can bring one down. With other food sources available, this quarry may be best left alone. The dire wolves will target moose (4 may be needed), elk, (2 may be needed), bison (6 may be needed), and even gaur (more than 6 will be needed). The Megalonyx may be targeted, and the wolves will be quick enough to surround it and avoid its claws, but a lot of time may be needed to bite through its tough hide. Styracosaurus, the Songhua river mammoth, and the woolly rhino will be avoided with all of the other prey available, but a large enough dire wolf pack can potentially take them down (many, many wolves will be needed for the mammoth).
Arctodus simus: The North American short-faced bear will be about 50% heavier than a Kodiak bear or a polar bear. It will probably look to overtake kills from other predators, but will attack prey also. The Utahraptor may try to attack it, but it should be able to overpower the dromaeosaurid most of the time. Groups of dire wolves and Deinonychuses may be trouble (the Deinonychuses may attack even if they don't have the numbers to have success), but this bear can easily kill one of these animals with a swipe or a bite. It won't waste its time trying to overpower a Megalonyx, but won't be in any danger from it. Arctodus might not be fast enough to catch the hooved herbivores without an ambush, but the moose and elk can be easily overpowered. The bison will be a challenge, and the stocky bovid may drive the bear away on occasion. Arctodus can potentially defeat a bison, but a gaur will be too strong. The "big 3" (mammoth, rhino, Styracosaurus) will be way out of the bear's league.
Utahraptor: This will be a very dangerous creature in the park. It may try to attack animals that are larger than it is without discernment, and a large group of them (assuming they hunt together), can potentially kill anything in the park. It may actually engage in skirmishes with the Deinonychuses (similar to it but 15% of its weight), but may actually coexist with them. A single Utahraptor can kill (and will try to kill) a moose, an elk, and a bison (but may lose this fight from time-to-time). It may try to attack a gaur, but will have trouble having any success in that encounter. It can harass a Megalonyx with its speed and mobility, and its weaponry can eventually cause serious wounds to the ground sloth. It can lose this fight, though. If a large number of Utahraptors leap upon one of the "big 3", they can eventually wear it down because they may be in a position that keeps them safe from an effective counter-attack. Nothing will really be 100% safe, and that includes the humans.
Deinonychus: These dromaeosaurids will likely run in packs (maybe large ones), and can be troublesome for many of the animals (including the humans and tigers). They will compete with the other predators (as mentioned in their sections), and can predate upon many of the herbivores. Several may be needed for the elk (3), the moose (4 or 5), the bison (maybe 6 or 7), and the gaur (as many as 8 or 9). They won't physically overpower these animals, but they will wear them down with the accumulation of injuries while staying out of the way (with lateral quickness or by clinging to the quarry) of the herbivore's offense. Even the tough exterior of the Megalonyx (Jefferson's ground sloth) won't guarantee safety form a large group of determined Deinonychuses. It's unlikely the dromaeosaurids will make any real effort to overcome any of the "big 3", but a tremendously large group of them could possibly succeed. This animal will be unpredictable, and will be the ones (along with the Utahraptors) to look out for when venturing out. The humans will need to keep a fire burning around the settlement to keep these creatures at bay. They will be harder to deter than the wolves.
Moose: Will be a popular choice for predators because it won't be beyond most of their capabilities, and will be able to feed a large predator or a large group of smaller predators. Will be a dangerous quarry with its wide-spreading antlers and sharp hooves. Will dominate the elk on most occasions, but will "give way" to all of the other herbivores that live around it. The bison, gaur, Daeodon, Megalonyx, and the "big 3" can bully it out of the way, but a peaceful coexistence will likely occur with most of them.
Gaur: Very strong bovid with thick horns and a muscular body. Will dominate the moose, elk, and bison for grazing areas (if they cross paths and if any conflict arises), and will likely get the better of any encounter with Daeodon and Megalonyx. The "big 3" (Songhua mammoth, woolly rhino, Styracosaurus) will be too large for the gaur to challenge in any way. The largest prey item that won't require extreme effort to overcome, but still a formidable quarry.
Jefferson's ground sloth (Megalonyx): 1-ton version of the huge Megatherium. Likely not aggressive or overly assertive against other herbivores, but well-armed with strong clawed forelimbs and well-protected by tough hide. Not a very fast or mobile animal, which may force it to be defensive in most hostile encounters. Will "give way" to the "big 3" in any situation, but may stand its ground successfully against any of the other plant-eaters (even if it can't win a fight against them). May actually get along well with the other plant eaters. Daeodon may be a rival if they meet, and the resulting contest can be a close one. Lack of speed may make it a target for the humans.
Bison: This 2,200lb giant will be a tough adversary for some, but it is only more dominant than the moose, the elk, and perhaps the Megalonyx. Good matchup for the Megalonyx in a hypothetical battle, and a good matchup for the Daeodon and Arctodus. Another decent animal to target as a food source (not to large to bring to camp and large enough to feed the group).
Elk: Even at over 1/2 ton in weight and well-antlered, this herbivore will be at the bottom of the totem pole among potential prey items. All other herbivores will be more powerful, and every predator can potentially kill it (only the dire wolves and the Deinonychuses will need more than one for a successful attack). It's a fast animal, and that is what makes capturing one potentially difficult.
Styracosaurus: Horned dinosaur weighing about 3 tons. Will dominate all other herbivores except the mammoth and perhaps the woolly rhino (which will be a confrontation that can go either way if the higher estimates for the rhino's weight are used). No single predator will be able to kill it, but a group of Utahraptors will come the closest. The humans might target one if it comes close to camp, but it will take a lot of weaponry to subdue this dinosaur. Will likely get along with all other herbivores. would defeat a mammoth at parity, but won't have a chance against one weighing at least 5 times more than it does.
Woolly rhino: Estimates for its weight range from 2 tons to 4 1/2 tons, but likely the 3rd most dominant single animal in the ecosystem after the mammoth and the Styracosaurus. Will have no trouble with any single predator, but a large group of Utahraptors (over 4) can subdue it. Several Siberian tigers would succeed, and huge groups of Deinonychuses and dire wolves would have a chance. The Daeodon and the Arctodus won't even look its way, and it will probably happily coexist with the other herbivores.
Songhua river mammoth: Regardless of which size we use (old size: close to 17ft at shoulder & over 19 tons; new size: 15ft at the shoulder and over 15 tons), this mammoth will be the king of the park. Only a massive group of Utahraptors will be able to threaten it, and the number of dire wolves or Deinonychuses required would be astronomical. More than a dozen Siberian tigers would be needed, and it would take several Styracosauruses and woolly rhinos to drive one away. This will be the safest animal in the park.
The colder seasons will favor the Siberian tiger, but will not favor the dromaeosaurids. The dire wolves will probably be the most adaptable; effective in any season.
