Resource Investment in Reproduction and Its Consequences in Three Pinguicula Species

Resource investment in reproduction and its consequences were compared for three iteroparous plant species, Pinguicula alpina, P. villosa and P. vulgaris, in a subarctic environment. Resource investment (dry matter, nitrogen and phosphorus) was estimated as reproductive effort, RE, and the consequences as relative somatic cost of reproduction, RSC, and as decreased post-breeding survival and reproduction. The relative reproductive allocation varied from 0.2 (N & P in large P. alpina plants) to 0.7 (dry matter of small P. villosa) (...)
