Evolution: are themonkeys’ typewriters rigged?
(2014)
Evolution is presumed to proceed by random mutations, which increase an individual’s fitness. Increased fitness produces a higher survival rate for those individuals within populations and drives the variants to fixation ...
Endocranial and masticatory muscle volumes in myostatin-deficient mice
(The Royal Society, 2014)
Structural and functional trade-offs are integral to the evolution of the mammalian skull and its development. This paper examines the potential for enlargement of the masticatory musculature to limit the size of the ...
Increased natural mortality at low abundance can generate an Allee effect in amarine fish
(2014)
Negative density dependent regulation of population dynamics promotes population growth at low abundance and is therefore vital for recovery following depletion. Inversely, any process that reduces the compensatory ...
Males migrate farther than females in a differential migrant: an examination of the fasting endurance hypothesis
(The Royal Society, 2014)
Patterns of migration including connectivity between breeding and non-breeding populations and intraspecific variation in the distance travelled are important to study because they can affect individual fitness and population ...
The subgenual organ complex in the cave cricket
(2014)
Comparative studies of the organization of nervous systems and sensory organs can reveal their evolution and specific adaptations. In the forelegs of some Ensifera (including crickets and tettigoniids), tympanal hearing ...
