Maternal effects in plants
Deborah A. Roach,Renata D. Wulff +1 more
TL;DR: It is contention that despite evidence that maternal effects can have a large in fluence on offspring phenotype, few detailed studies have identified the specific causes of maternal effects, particularly in natural populations.
Journal ArticleDOI
The case for negative senescence.
TL;DR: It is concluded that negative senescence may be widespread, especially in indeterminate-growth species for which size and fertility increase with age, and optimization models of life-history strategies are developed that demonstrate that negativesenescence is theoretically possible.
Journal ArticleDOI

TL;DR: It is found that long-distance dispersal and repeated introductions by humans have shaped adaptive potential in a globally distributed invasive species, highlighting the need to constrain future introductions of species even if they already exist in an area.
Journal ArticleDOI
Reproductive Strategies of Pioneering Alpine Species: Seed Production, Dispersal, and Germination
TL;DR: In this article, Reproductive characteristics for four plant species identified as potential early colonizers of disturbed alpine tundra in the White Mountains of New Hampshire are reported for Arenaria groenlandica.
Journal ArticleDOI
Multigenerational effects of flowering and fruiting phenology in plantago lanceolata
TL;DR: The hypotheses that there are cross-generational trade-offs between parental and offspring components of parental fitness influencing the evolution of reproductive phenology and multigenerational fitness effects in Plantago lanceolata are tested are tested.
