The higher stoat numbers reduce the rodent population and the stoats then prey on birds. [6] For instance, the wild population of the endangered takahē dropped by a third between 2006 and 2007, after a stoat plague triggered by the 2005–2006 mast wiped out more than half the takahē in areas where stoat numbers were not limited by trapping.

Skull. The root word for "stoat" is likely either the Dutch word stout ("bold") [4] or the Gothic word 𐍃𐍄𐌰𐌿𐍄𐌰𐌽 (stautan, "to push"). [5] According to John Guillim, in his Display of Heraldrie, the word "ermine" is likely derived from Armenia, the nation where it was thought the species originated, [4] though other authors have linked it to the Norman French from the ...
Scarcity during colonial history may have been due to early spread of brown rats and feral cats throughout New Zealand; a captive bird showed alarm at the presence of a cat. Final extinction coincided with the first expansion of stoats on the West Coast Region, before the wetlands were drained for farming. [87]
Marine mammals comprise over 130 living and recently extinct species in three taxonomic orders.The Society for Marine Mammalogy, an international scientific society, maintains a list of valid species and subspecies, most recently updated in October 2015. [1]
The near extinction of the formerly widespread South Island takahē is due to a number of factors: over-hunting, loss of habitat and introduced predators have all played a part. The introduction of red deer (Cervus elaphus) represent a severe competition for food, while stoats (Mustela erminea) take a role as predators.
The short-tailed weasel is the common name in North America for two species once considered a single species: . Stoat or Beringian ermine (Mustela erminea), native to Eurasia and the northern portions of North America
More than 80% of ships are speeding through "go slow" zones set by environmental regulators along the U.S. East Coast to protect endangered North Atlantic Right Whales, according to a report ...
Global extinction approximately 65 Ma (million years ago) resulted in the loss of fauna such as non-avian dinosaurs, pterosaurs and marine reptiles e.g. mosasaurs, elasmosaurs and plesiosaurs. [1] The ancient fauna is not well known, but at least one species of terrestrial mammal existed in New Zealand around 19 Ma.
