Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.

This coast has an arctic climate warm enough to allow plant growth in late-June, July and August only, and even then frosts may occur. On the whole this is a damper, wetter area than the Low Arctic tundra ecoregion that continues along the coast west of here to Quebec. [2]
Animal species that are endangered in the tundra include the Arctic fox, caribou, and polar bears. These animals have been endangered due to overhunting, an infestation of disease, loss of diet and habitat due to climate change, and human destructive activities, such as searches for natural gas and oil, mining, and road building.

The arctic tundra often lacks sunshine. Summer days last 24 hours, yet the sun remains low on the horizon. During the winter, the opposite occurs, and the entire landscape is dark.
Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million in total. Animals range in size from 8.5 millionths of a metre to 33.6 metres (110 ft) long and have complex interactions with each other and their environments, forming intricate food webs .
This was the Arctic’s second-hottest year on record, according to a new NOAA report. The tundra has become a source of emissions, rather than a carbon sink, the authors said. The Arctic is ...
