Amoeboid organisms also display feeding selectivity.
Evidence suggests that a reaction between chemical compounds on the surface of the prey and the tentacle tip of the suctorian is responsible for feeding selectivity.
We recorded the activity and feeding selectivity of the camels, as well as the consumption and recovery of the common perennial plant species.
The numbers of horses grazing at pasture are increasing in developed countries, so a proper understanding of their feeding selectivity and of the tactics they use for extracting nutrients from swards is essential for the management of horses and grasslands.
Feeding selectivity in shallow water species has only been shown at the bulk level (fresh vs. old detritus) [26], [37] and not at the pigment level.
It appears that feeding selectivity for labile organic material and biochemicals is more pronounced at greater water depths as a result of lower food inputs [49].
Recently, feeding selectivity has been demonstrated at the biochemical level using specific biomarkers, including fatty acids, sterols, and photosynthetic pigments (e.g. [28] [31]).
For example [37] detected feeding selectivity for organically enriched patches in M. intestinalis and P. tremulus, whilst [72] found no evidence of selection by particle size or for organically enriched particles in shallow water holothurians.
Feeding selectivity for faecal casts, organically enriched particles, or certain particle sizes has been found for many shallow water echinoderms (e.g. [71]), but this ability is thought to vary between species and habitats.
Specifically, we investigate whether each species exhibits feeding selectivity for particular phytoplankton pigments (chlorophylls and/or carotenoids) and whether such partitioning of resources positively affects resource use when species are in mixture.
Meng et al. [70] studied the effect of temperature on feed conversion, selectivity of total light olefins and product distribution in the reaction temperature range of 600 716 °C using a CEP-1 catalyst.
