to be well-developed in young flies, behaviors that rely on more complex motor programs, such as courtship and aggression, exhibit ontogenetic changes which may stem in part from ongoing refinement ...
physiological mechanisms, the synergistic cooperation between stem height and radial growth can help trees’ success in survival, function and reproduction. However, when resources are short in supply, a greater ...
., 2011). Analysing these responses has led to the identification of two different components of the support function: (i) a skeletal design based on stem thickness and taper together with the strength ...
Abstract Recent successes in the stem cell field have identified some of the key chemical and biological cues which drive photoreceptor derivation from human embryonic stem cells (hESC) and human ...
