A few additional examples further illustrate the wealth of adaptations in selective feeding.
Selective feeding requires good sensory and nervous equipment and, in most cases, considerable mobility.
Selective feeding, food procurement in which the animal exercises choice over the type of food being taken, as opposed to filter feeding, in which food is taken randomly.
Vertebrate herbivory may result in changes in tundra vegetation through selective feeding on preferred plant species, trampling, and recycling of soil nutrients through excretion.
The increased level of Zn and Fe in vermicompost indicated accelerated mineralization with selective feeding by earthworms on materials containing these elements.
It is this shift in N/P, and possibly some level of selective feeding, that is believed to have driven changes in the relative abundance of Microcystis.
This alteration in the amount of soil separates is possibly due to selective feeding, physical grinding by gizzard and redistribution of soil particles by means of earthworms casting activities (Edwards and Bohlen 1996).
Contrary to expectations, neither δ13C nor δ15N values are strong predictors of moisture variables, which may be due to micro-scale topographic and environmental variation and selective feeding strategies.
However, the selective feeding of Nereis spp. on fresh plants, animals and microorganisms at the sediment surface associated with suspension feeding, subsurface defecation and mucus secretions along burrow walls may redistribute significant amounts of reactive organic matter within the sediment.[9].
Crucial aspects of pastoralist specialisation are: 1. the interaction of people, animals and the environment, particularly strategic mobility of livestock and selective feeding; and 2. the development of flexible resource management systems, particularly communal land management institutions and non-exclusive entitlements to water resources (ibid).
