Ecologists call these consumptive interactions trophic interactions. And so, species engaging in a particular kind of trophic interaction are said to belong to a distinct trophic group. Ecologists routinely idealize food chains and webs as being comprised of four trophic groups.
Species that consume mineralized nutrients and CO2 in order to photosynthesize carbohydrates belong to the plant trophic group, species that consume living plant tissue belong to the herbivore trophic group, species that prey on herbivores belong to the carnivore trophic group, and species that recycle dead organic material back into the nutrient pool belong to the Oddities of kingdom plantae trophic group.
Such classic idealization of ecological systems typically ignores another trophic group, scavengers. After all, mobs of bloody headed vultures vying for their share of a carcass or insect larvae crawling in stinking, rotting meat do not engender the same sense of awe and natural wonder as do grazing antelope and lions coexisting on the Serengeti plains of Africa.
Scavengers get short shrift in ecological thinking because their role is typically viewed as being a repulsive behavioral curiosity or the ecological equivalent of garbage men that sustain themselves on nature's offals.
Scavengers are sometimes viewed merely as parasites that steal food - called kleptoparasitism - from the more noble carnivores. These are, however, unfortunate and inaccurate characterizations of scavenging. As we will show below, scavenging serves an important role to the welfare of many species and it can be an important determinant of the structure and functioning of ecological communities.
Moreover, scavenging involves many more species than those few specialists that are routinely highlighted as serving this role.
Scavenging as a Trophic Interaction Scavenging, like carnivory, involves the act of consuming the flesh of dead animals - carrion. Technically, however, scavenging differs from carnivory in that it does not actively involve killing animals.
Scavengers also differ from decomposers. Decomposers like bacteria and fungi break down the protein of dead animals into its constituent carbon- nitrogen- and hydrogen-based elements Figure 1.
Those elements are then broken down further into mineralized form to be taken up later by plants. Scavengers, on the other hand, consume organismal protein and convert it into their own body tissue Figure 1. Research has shown that many organisms die from sources other than predation. In the Serengeti alone, the annual amount available to scavengers is estimated to be on the order of 26 million kg.
Clearly, neither the Serengeti plains, nor any other location globally, is littered with dead animal carcasses, testimony to the magnitude of this trophic interaction.
Depending on the size and species of carrion, a carcass can be despatched within hours to days.
Scavenging can be temperature dependent because of interplay between microbial decomposition and chemical detection of carcasses. This interplay leads to intermediate, optimal temperatures for scavenging, especially within temperature regions of the globe.
Decomposers alone are rarely able to utilize entire carcasses. So, to avoid competition with scavengers, decomposers have evolved capacities to produce noxious and odorous chemicals that can make the entire carcass distasteful or even toxic.Jan 30, · There are, however, a few oddities.
The sole basis of Epidendrum domesticum L., a name that has been associated with Vanilla, is an Engelbert Kaempfer plate, close study of which suggests that it is a composite of an orchid and a member of Iridaceae.
