LifespanIndispensable soma hypothesisIt is not surprising that one of the most complex phenomena in nature is that of ageing. It does not only bear biological interest, but it is also associated with cultural, psychological, social and even philosophical issues. It is therefore to be expected ...
If these needs are not met in childhood, and throughout thelifespan, problems will occur. 如果在童年期和随后生命期中这些需要未被满足, 就会出现问题. 期刊摘选 But one striking piece of inequality has been conveniently overlooked:lifespan.
Throughout the life span, a single female S. galinae produced a mean (+/- SE) of 31 (+/- 3.0) progeny when reared in groups, and a mean (+/- SE) of 47 (+/- 5.3) progeny when reared in single pairs. Results from our study also showed that S. galinae could be effectively ...
Plasticity, the capacity for change in response to experience, exists throughout the life span. Plasticity is distinct from flexibility, defined by one's current skill set that enables adaptation within a particular range of demands, and implies the ability to both gain in efficiency and form new...
This article provides an overview of the concept of life span. Life span is an evolved life-history characteristic of an organism that refers to the duration of its life course. Application of the concept is straightforward at both individual and cohort levels: it specifies the period between bi...
The concept thatlifespanis a function of the capacity to withstand extrinsic stress is very old. In concordance with this, long-lived individuals often have increased resistance against a variety of stresses throughout life. Genes underlying the stress response may therefore have the ability to affe...

Life-span approach;Life-span process Definition A key assumption of theories on life-span development is the belief that no process of development is only characterized by gains and progression, but that development always involves both gains and losses, even though the ratio between gains and loss...
According to Xia, the governance practice of ancient China faced particular difficulties. "For example, throughout history, China's population has comprised a large proportion of the global population, about 20 to 30 percent o...
either directly or through its effects on behavior, while estrogen levels extend lifespan (Brooks and Garratt2017). Testosterone also plays an important role in limiting expression of alternative male phenotypes (i.e., polymorphism in physiological, behavioral, morphological and life history differences...
