The migratory woodland caribou refers to two herds of Rangifer tarandus (known as caribou in North America) that are included in the migratory woodland ecotype of the subspecies Rangifer tarandus caribou or woodland caribou [1] [2] that live in Nunavik, Quebec, and Labrador: the Leaf River caribou herd (LRCH) [3] [4] and the George River caribou herd (GRCH) south of Ungava Bay.
Their neurosensory capabilities such as hearing and olfaction (sense of smell) were unexceptional, and their gaze stabilisation less developed than those of spinosaurines, so their behavioural adaptations were probably comparable to those of other large-bodied terrestrial theropods.
ɪ f ɔːr m iː z / is an order of large flightless birds that has four surviving members: the three species of cassowary, and the only remaining species of emu. They are divided into either a single family, Casuariidae, or more typically two, with the emu splitting off into its own family, Dromaiidae.
The Baldwin effect only posits that learning ability, which is genetically based, is another variable in / contributor to environmental adaptation. First proposed during the Eclipse of Darwinism in the late 19th century, this effect has been independently proposed several times, and today it is generally recognized as part of the modern synthesis .
This behavioral adaptation coincides with the chimpanzee's ability to distinguish kin from non-kin (referred to as visual kin selection) allowing chimps to formulate large, complex societies, where they use altruistic methods to ensure their genes persist in future generations. [7]
The work above is just one example of an ecomorphology based behavioural study. Studies of this variety are becoming increasingly important in the field. Behavioural studies interrelate functional and eco-morphology. Features such as locomotory ability in foraging birds have been shown to affect dietary preferences by studies of this type. [11]
The emu (/ ˈ iː m juː /; Dromaius novaehollandiae) is a species of flightless bird endemic to Australia, where it is the tallest native bird. It is the only extant member of the genus Dromaius and the third-tallest living bird after its African ratite relatives, the common ostrich and Somali ostrich. The emu's native ranges cover most of the ...
The common ostrich is the largest and heaviest living bird. Males stand 2.1 to 2.75 m (6 ft 11 in to 9 ft 0 in) tall and weigh 100 to 130 kg (220 to 290 lb), whereas females are about 1.75 to 1.9 m (5 ft 9 in to 6 ft 3 in) tall and weigh 90 to 120 kg (200 to 260 lb). [20]
