- this is not true for the big cats, and nor is it true
for most pack-hunters; i suspect it is not true for most
obligate wild carnivore species, as any predator species
that destroys one hundred per cent of its possible prey
species - or anything remotely resembling this - destroys
itself. the domestic cat and dog are certainly capable
of destroying local populations of some species, especially
where introduced into "island" (isolated) ecosystems that
previously lacked any comparable predator, as is the humble
hedgehog(!); but iirc the success rate of the big predators'
hunts is around one kill in ten - low enough to be coped
with by the prey species, and the rate of reproduction of
the big predators is low enough to maintain a population
sufficient to expand only relatively slowly, even when one
or more of the prey species increases considerably and rel-
atively quickly. big predators occupy large territories
and prey upon migratory animals, as a rule; but hunting is
itself dangerous for them, and they are intolerant of any
other (non-pride member, if lion) big cat in the territory,
of whatever species. this is why c.j. cherryh chose her
leonine spacefaring species in the chanur sequence, the hani,
to be primarily a pride-based civilisation, somewhat extended
to a workable kith-based clan structure, naturally somewhat
imperfectly: co-operation is necessary for culture to arise.
- i believe it's mainly in ecologically marginal territories
that they are likely to outbreed their food supply to the
point of death by starvation being anywhere near the norm
for their young. by and large the big cats spend more time
sleeping, lazing, digesting, grooming and playing (especially
females with their young) than hunting - which they would
scarcely do, if starving.
- predator species' weaponry and prey species' defences
tend to co-evolve, maintaining an approximate parity;
domestic cats and their more distant cousins' ability to
expand populations rapidly may be linked to the propensity
of their small mammal prey species populations to explode
occasionally - explode in number, that is, not percussively.
(- though that _would_ make for an *_interesting_* range
of problems for predators and rpg adventurers alike ;-) )
>Plants are even worse, naturally.
- very few plants are obligate carnivores, and scarcely any
are known habitually to go abroad hunting their prey.
