“…This type of distribution has been attributed to either the dispersal of individuals outwards from a 'metropolis' of high abundance (Grinnell 1917) or the decreasing physiological tolerance of individuals to changes in abiotic conditions (e.g. temperature) along an environmental gradient towards their range limits (Shelford 1911). Although a few terrestrial species have been shown to conform to the abundant-centre distribution (e.g.…”

Patterns of demography for rocky-shore, intertidal invertebrates approaching their geographical range limits: tests of the abundant-centre hypothesis in south-eastern Australia. Marine and Freshwater Research, 61 (11), 1243-1251. Patterns of demography for rocky-shore, intertidal invertebrates approaching their geographical range limits: tests of the abundant-centre hypothesis in south-eastern Australia AbstractThe abundant-centre hypothesis predicts that species' abundances peak at the centre of their geographical ranges and decline gradually towards their range limits. We tested predictions of this hypothesis for three rocky-shore, intertidal invertebrates with planktonic larvae (the whelk, Morula marginalba, the snail, Afrolittorina pyramidalis, and the barnacle, Tesseropora rosea) by quantifying their patterns of abundance and size, and inferring pulses of recruitment from size-frequency distributions, at multiple spatial scales spanning a 600-km region in south-eastern Australia and encompassing roughly the southern third of their geographical ranges. At the regional scale, abundances for all species were, as predicted, dramatically lower at their range limits. This decline was not gradual, however, because there were large variations in abundance at smaller spatial scales, and abrupt declines at the south-eastern corner of Australia. Size did not change towards the range limit for any species, but size-frequency distributions suggested a decline in the frequency of recruitment events at the range limit for T. rosea. We conclude that the abundant-centre hypothesis is not an appropriate model for abundance distributions of benthic marine invertebrates with planktonic larvae, because of the vagaries of dispersal and recruitment interacting with complex current patterns along nonuniform coastlines.

The breeding success of puffins (Fratercula arctica) in different habitats was studied on Great Island~ Newfoundland. A . multiple regression analysis showed that puffin burrow density was negatively correlated with distance from the cliff edge~ and positively correlated with angle of slope.The biological significance of these correlations was found to be that close to the cliff edge, where the angle of slope is steep, breeding success is significantly higher than on adjacent level habitat. The reasons for the difference in breeding success are~ firstly, eggs and chicks are more exposed to gull predation on level habitat, and secondly, parents are more vulnerable to robbing by gulls when taking food to chicks on level areas than when taking food to chicks on slope habitat. Thus, during the breeding season, natural selection acts more strongly against birds nesting on level habitat away from the cliff edge than against those nesting close to the cliff edge.In the absence of gull Interference puffins showed higher breeding success. A model is presented which relates the distribution of puffin nests to habitat characteristics in the presence and absence of gulls .

“…Thus, it is possible that C. cursitans may use clayey, silty, or rich organic soils. Other studies have shown that tiger beetles select oviposition sites based on soil type (Shelford 1911) and that the shape of the female ovipositor is related to the particle size of the preferred substrate (Leffler 1979).…”
