Abstract

This review reports on the processes associated with costs of reproduction, including some theoretical considerations, definitions and methodological aspects, followed by a list of the situations where costs are difficult to find. Despite some exceptions, case studies, examined by trade-offs between reproduction and other life-history traits, generally support the predictions of the cost of reproduction hypothesis. The cost of reproduction as an evolutionary determinant of sexual dimorphism in life history traits in dioecious species was specifically tested, considering that the higher cost of reproduction in females has driven the life history traits related to sexual dimorphism. Females of woody dioecious species were consistently smaller than males supporting the costs of reproduction hypothesis. By contrast, females of herbaceous perennials were generally the larger sex, which did not fit the expectations of the hypothesis. Finally, the mechanisms that enable the compensation of the reproductive costs are detailed, including the plastic responses of photosynthesis and growth, the effects of the timing of investment, plant architecture and plant physiological integration.© New Phytologist (2002) 155 : 321 -348

“…Parkinson's disease (PD) is a neurodegenerative and progressive disorder that affects motor and cognitive functions [1] and nearly 1 % of the population over the age of 60 [2]. According to Magill et al, PD is associated with an increment in the oscillatory activity in the outer and intern part of the globus pallidus and particularly in the neurons of the subthalamic nucleus (STN) [3] [4]. There are quite effective medications to treat the motor symptoms of PD.…”
