Abiotic factors influence the flow of interaction in an environment so it is an important move to study their effects on living organisms. Cavity nesting animals such as bluebirds, nuthatch, wrens, screech owls, squirrels and woodpeckers have very little, if any, shelter available. The topsoil blows away, and the natural vegetation does not reproduce, not finding suitable mediums. In its spread across Australia, the rabbit took advantage of pre-existing burrows and evicted various burrowing mammals such as the rufous hare-wallaby. The impact on small predators was bad, lynxes, foxes and several birds of prey that depended on eating rabbits declined drastically. Predict: Based on your hypothesis, predict how changing the rabbit population will affect the other organisms at first. Rabbits cause damage to the environment by: - Overgrazing on native and/or sown shrubs and plants - Increasing and spreading the amount of invasive weeds which overtake crops - Building and digging burrows/warrens which cause land degradation In another example, let's assume all the dead hollow trees are removed from a forest ecosystem. The community also suffers indirectly, as they might pay higher prices for rabbit-affected commodities (such as wool) 2 or bear the loss of ecosystem services at the catchment scale 3. They also found that combinations of predators , such as wolves and bears, can create an important synergy for moderating the size of large herbivore populations. Rabbits gain moisture from their food and do not need access to water, except in semi-arid areas. Question: An ecosystem is a group of living things and their physical environment.
