Web0-1 scale. We do not make such a transformation, because the index has other problems (see below). EQ = -2/ir arctan(b') where: b' = the slope of the scaled rank of abundance on log abundance, fitted by least-squares regression. [arctan is assumed to provide an angle in radians.] The ranks are scaled before the regression is fitted, by Web1. : an ample quantity : an abundant amount : profusion. a city that has an abundance of fine restaurants. 2. : affluence, wealth. a life of abundance. 3. : relative degree of plentifulness. …

WebOct 30, 2013 · Using a robust regression over three generations allowed us to estimate in a statistically sound manner the dominant recent abundance trends for the largest number of marine mammal populations, as scaled to life history and comparable to IUCN methods . In a few cases, historical estimates were included in the 3-generation regression timespan ...
WebMar 1, 2024 · Many populations of southern hemisphere baleen whales are recovering and are again becoming dominant consumers in the Southern Ocean. Key to understanding the present and future role of baleen whales in Southern Ocean ecosystems is determining their abundance on foraging grounds.

WebSep 4, 1998 · Here, a scale-independent measure of species abundance is developed, using presence-absence maps at varying spatial resolutions. By extrapolating such “scale-area” curves, species abundance can be estimated accurately even at scales finer than those used to parameterize the model, a task that had previously been deemed impossible in principle. WebMay 17, 2024 · The global-scale abundance estimates that we provide will allow for a line of inquiry into the structure of abundance across biogeographic realms and feeding guilds as well as the consequences of life history (e.g., body size, range size) on population dynamics. Importantly, our method is repeatable and scalable: as data quantity and quality ...
