Common use of Incidence Clause in Contracts

Incidence. the balance between ingestion and regurgitation/excretion Figure 1. The two extremes among birds in terms of ingested plastic dynamics: species such as gulls (left) regularly regurgitate pellets of indigestible prey items, including plastics, and thus for a given ingestion rate, contain less plastic in their stomachs than species such as petrels (right) that seldom regurgitate and so accumulate ingested plastics in their gizzards, where it is gradually eroded until it is small enough to be excreted (from ▇▇▇▇ 2016). Table 1. Numbers of seabird species reported to ingest plastic items, the proportions of each family (or sub- family) affected (expressed as a function of all species, and of those species specifically checked for ingestion), and the mean incidence of ingestion per species (the proportion of individuals within each species containing plastic, restricted to species with at least 10 individuals examined) [from ▇▇▇▇ 2016]. Figure 2. The relationship between the proportion of species in each seabird family or sub-family containing ingested plastic (excluding species not examined) and the average incidence of plastic load per species, based on data in Table 1. Groups not labelled = cormorants, sulids, loons, diving petrels.
