Functional adaptation rather than ecogeographical rules determine body-size metrics along a thermal cline with elevation in the Chinese pygmy dormouse (Typhlomys cinereus) by Cui, J, Lei, B, Newman, C, Ji, S, Su, H, Buesching, C, Macdonald, D, Zhou, Y

“…Based on a sample of 67 adult individuals (female, n = 29; male n = 38) trapped at 37 sites transcending an elevational range from 414 to 1757 m, we tested for trait concordance with Bergmann's rule (body mass, length and SMI), Allen's rule (length of tail, foot, ear, snout), and Hesse's rule (wet and dry heart mass). …”

Food resources and competition rather than eco-geographic rules explain trait variations in two contrasting rat species: Implications for future climate change by Jifa Cui, Boyu Lei, Chris Newman, Youbing Zhou, Zhiping Wang

“…There was no support for Allen's rule, except for a contrary effect on snout length among females; however, greater intraspecific competition and lesser food abundance were associated with shorter snout length, supporting Geist’s rule. …”

The incredible shrinking puffin: Decreasing size and increasing proportional bill size of Atlantic puffins nesting at Machias Seal Island. by Heather L Major, Joy E Rivers, Quinn B Carvey, Antony W Diamond

“…Climate change imposes physiological constraints on organisms particularly through changing thermoregulatory requirements. Bergmann's and Allen's rules suggest that body size and the size of thermoregulatory structures differ between warm and cold locations, where body size decreases with temperature and thermoregulatory structures increase. …”
