متن کاملGenetic Redundancy: Desirable or Problematic for Evolutionary Adaptation?
Evolution is commonly viewed as a process of hill climbing on a fitness landscape. A major problem with such a view is the presence of local optima; sub-optimal regions of the landscape from which no further progress is possible. There is an increasing amount of evidence [3,4,7], however, that the presence of large degrees of redundancy in the genome may alleviate this problem through the creat...
متن کاملStress adaptation and the resilience of youth: fact or fiction?
The young are resilient! This age-old adage refers to the ability of the young to adapt to changing stress in the environment. The origin of these stressors can be physical (pollution, nutrient status, infections) or psychological (trauma, parenting, home environment). Resilience is the ability to adapt to a changing environment, and this adaptive stress response (also known as allostasis) is c...
متن کاملResistance, resilience, and redundancy in microbial communities
Although it is generally accepted that plant community composition is key for predicting rates of ecosystem processes in the face of global change, microbial community composition is often ignored in ecosystem modeling. To address this issue, we review recent experiments and assess whether microbial community composition is resistant, resilient, or functionally redundant in response to four dif...
