Although the importance of carrion decomposition in the atmosphere has long been recognized, the processes behind it have yet to be elucidated.
Understanding its position in the overarching ecological system is crucial to the overall understanding of ecology. Carrion is an inevitable and ecologically important component of the ecosystem.
#CARRION SWITCH PHYSICAL DRIVERS#
Spatial and temporal dynamics of detritus subsidies, along with competitive hierarchy of species using these resources, are important drivers of terrestrial system decomposition processes and are ultimately related to necrophages through evolutionary processes. In addition to impacting landscape heterogeneity through decomposition pattern destruction, decomposers such as scavengers also impact the structure of other trophic levels through their encounters with predators, parasites, and other organisms. Scavengers feeding upon carrion help to recycle carcass nutrients and resources throughout the ecosystem. From a physical standpoint, after an animal dies, its molecular structure begins to disaggregate. Decomposition in any given ecosystem includes actions of vertebrate scavengers, invertebrates, plants, and microorganisms. Understanding this process is therefore important to understanding the way an environment works as a whole. Carcass decomposition changes the surrounding environment both in the short term and in the long term. While plants make up a good portion of the detrital pool, carrion, also considered detritus, is the decaying flesh of dead animals and has a significant impact on the ecosystem. Detritus is the term for any source of non-living organic matter and is the basal trophic stage of most food webs, believed to be produced from phototropic sources.
