Contre les duperies écologiques, Jean de Kervasdoué veut faire entendre l. a. raison. Un essai vigoureux et utile.
" Il n'y a pas d'autres domaines que l'écologie où les préoccupations les plus justifiées voisinent avec les plus évidentes bêtises, où los angeles confusion des options est aussi manifeste, où les croyances l'emportent sur los angeles raison, où l. a. pression sociale est aussi sirupeuse que violente, où l'idéologie prend le masque de los angeles vérité, où les intérêts se cachent sous l. a. bannière de l. a. générosité, où les informations sont partielles, partiales et souvent truquées. Cette bouillie de pretend ideas, de grands sentiments et d'intérêts camouflés conduit les hommes les plus respectables à proférer doctement les plus évidentes contrevérités, à prendre los angeles plaine de l. a. Beauce pour le Sahel, à considérer que le réchauffement climatique affecte Bordeaux comme Tombouctou, que le débit du Rhône est celui du Jourdain, que l. a. dégustation d'un steak est aussi dangereuse que l. a. traversée à l. a. nage du détroit de Magellan et, surtout, à prendre les plus incontestables bienfaits de los angeles technology pour le plus grand des hazards. Pourquoi ce fossé entre l. a. réalité et sa conception ? " Jean de Kervasdoué

Houston (1974:18) commented that all censuses from 1935–68 were made after the hunting seasons and park removals. The mean, estimated fall populations for the censused years of the 1920s, 1930s, and 1940s were 14,624, 13,918, and 14,239. 1% of the estimated fall numbers. On average, the population evidently maintained its numbers in the face of these hunting removals. But the averages do not disclose the detailed trends in the population. The gaps in the data complicate interpretation and make it tentative.

Hunter-gatherer cultures depended heavily on plant resources. Fishing was also important between late spring and early fall. Winter was spent outside the area hunting ungulates, the inhabitants of the park area moving north to the plains in search of bison. Jackson Hole occupants moved southeast in winter to the Green River–Red Desert area or west into Pierre’s Hole. No evidence was found that large numbers of elk occurred in Jackson Hole in either winter or summer. Kay (1990), in addition to quantifying the ungulate remains in archaeological sites around the Yellowstone area, analyzed data from sites throughout the Intermountain West.

This effect is perhaps to be expected because the tendency for the animals to move north out of the park has increased as the herd size has grown (Coughenour and Singer 1996; Lemke et al. 1998) and thus become increasingly vulnerable to hunting. But the total density dependence operating on the population only accounts for 23–55% of the variance in r. Thus, perhaps half to two-thirds of the variance is associated with density-independent influences in the environment and with measurement error.
