Dietary Adaptations You are what you eat. You've heard that one before, haven't you? It's a bit of an exaggeration. You won't really become a doughnut even though you may munch on them all day, but your body may modify its shape in response to the empty calories. T...
“Our findings demonstrate that multiple eco-adaptations have contributed to the diverse mandibular structure found in proboscideans,” concludes senior author Dr. Shi-Qi Wang, professor at the Key Laboratory of Vertebrate Evolution and Human Origins of the Chinese Academy of Sciences. “Initially, ...
Abstract鈥 A cladistic viewpoint provides an historical definition of adaptation and an operational ecological test for evolutionary adaptations. Adaptatio... JA Coddington - 《Cladistics-the International Journal of the Willi Hennig Society》 被引量: 1060发表: 1988年 Dietary Restriction and Aging Diet...
The specific adaptations Homotherium had acquired would have suddenly become less advantageous, leaving the lineage stuck on a path to extinction. Conclusions The genome sequence of the scimitar-toothed cat, Homotherium latidens, improves our understanding of its evolutionary relationships with other ...
which may be the result of the complex digestive physiology that has evolved in ruminants. The putative keystone species identified in our co-occurrence analysis may be of special interest for future work determining how dietary changes can modulate the animal gut microbiome, such as in the context...
metabolic balances, these observations point out that hormetic responses are ecological adaptations and not resulting from physiological trade-offs. The pathogen control hypothesis may explain this phenomenon. Since the evolution of lifespan is driven by population pressures, the pause in reproduction ...
A considerable amount of cladogenesis and speciation in this period is likely to be the result of non-adaptive allopatric divergence or adaptations to peaks within major dietary categories. 展开 关键词: Biological Sciences(General Ecology Evolution Behavior and Systematics ...
Teeth act as tools for acquiring and processing food, thus holding a prominent role in vertebrate evolution. In mammals, dental-dietary adaptations rely on tooth complexity variations controlled by cusp number and pattern. Complexity increase through cus
The differently colored lines of best fit represent the SGR changes in the test characters on the space-time scale. The colored stars indicate the peak values of the SGR for different test characters. Principal component analysis was performed to examine the character differentiation of the coprop...
A variety of nut-producing plants have mutualistic seed-dispersal interactions with animals (rodents and corvids) that scatter hoard their nuts in the soil
