Most classical preyâpredator models do not take into account the behavioural structure of the population. Usually, the predator and the prey populations are assumed to be homogeneous, i.e. all individuals behave in the same way.ence, there is only a positive nontrivial equilibrium when. This is the dimorphic case where the predator population consists of hawk and dove predators. There are also the two trivial equilibria, the monomorphic cases, (pDH*,pDD*)=(0,pD*) (only doves) and. (only hawks).
Wood Shavings. White wood shavings (dust extracted, not sawdust) is one of the most popular bedding materials for chickens, ducks and other poultry as they are relatively cheap, very absorbent and easy to use.Shavings keep smells down and reduce ammonia in the air from droppings that can cause respiratory damage and eye problems.t is best to use straw in nest boxes and not for bedding. I would only consider using straw if I had a plentiful / cheap supply of it. Chopped straw is the most convenient to use. A major advantage is that it will compost quickly.
