carnivorous plants

plants which obtain at least some of their nutrients by trapping small animals, usually insects. In the UK such plants often grow in boggy places where nitrogen is difficult to obtain, extra nitrogen being extracted from the bodies of captured prey. The sundew Drosera and the bladderwort Utricularia are the commonest British carnivorous plants and are protected species.

Carnivorous plants were something that fascinated him from a very early age.
In addition to prey relationships and entrapment mechanisms, there are presentations regarding the connnensalism and mutualism aspects of some species, particularly in Nepenthes, along with an array of discussions on habitats and the general ecology of carnivorous plants. There is also an assessment on the contemporary vulnerability of carnivorous plants with regard to anthropogenic impacts on their various habitats, bolstered by various models of species distribution and exposure lo broader impacts, such as accelerated climate change.
Much of the native habitat of carnivorous plants is under threat; reputable nurseries propagate without harming wild populations.
There are two other techniques also used by carnivorous plants: snap traps and lobster-pot traps.

Nevertheless, in spite or perhaps because of the proximity of their publication dates, this hoax in fact shows the greatest debt to Darwin's work on both evolution and carnivorous plants, as its (fictional) author compares the contents of the letter he is about to share with Darwin's "studies of drosera and sarracenia [the North American pitcher plant]," and compares himself to Darwin publishing on evolution: "My special and only motive for publishing prematurely [...] is similar to that which influenced Darwin to bring out his book on the origin of species" (Arment, Botanica Delira 47).
Most common carnivorous plants use leaves above the ground to trap their prey.
Presence of potential animal prey for carnivorous plants may vary among environments and seasons, so that different populations of plants establish themselves in the presence of particular communities of prey (Zamora et al., 1998; Alcala and Dominguez, 2003).
