The jaguar (Panthera onca) is a large cat species and the only living member of the genus Panthera that is native to the Americas.With a body length of up to 1.85 m (6 ft 1 in) and a weight of up to 158 kg (348 lb), it is the biggest cat species in the Americas and the third largest in the world.
The average global population of all mature birds is estimated to be on the order of 100 billion individuals. [1] [2] [3] The total population including younglings is somewhat higher during the breeding season of each species. [3] This list is incomplete, because experts have not estimated all bird numbers.
Despite the declining population of cougars, the potential extinction of the North American Cougar is not seen as a large concern. [26] In Oregon, a population of 5,000 individuals was reported in 2006, exceeding a target of 3,000. [34] California has actively sought to protect the cat and has an estimated population of 4,000 to 6,000. [35]
The Jaguar is the third biggest cat in the world, after the tiger and the lion, and the largest in the Americas. They grow up to 170 cm (67 inches) long, not including their impressive tails that ...
Species population is a science falling under the purview of population ecology and biogeography. Individuals are counted by census, as carried out for the piping plover ; [ 3 ] [ 4 ] using the transect method , as done for the mountain plover ; [ 5 ] and beginning in 2012 by satellite, with the emperor penguin being first subject counted in ...

The rank abundance curve visually depicts both species richness and species evenness. Species richness can be viewed as the number of different species on the chart i.e., how many species were ranked. Species evenness is reflected in the slope of the line that fits the graph (assuming a linear, i.e. logarithmic series, relationship).
A population of 240 panthers would require 8,000–12,000 square miles (21,000–31,000 km 2) of habitat and sufficient genetic diversity to avoid inbreeding as a result of small population size. However, a study in 2006 estimated that about 3,800 square miles (9,800 km 2 ) were free for the panthers. [ 50 ]
