比较了亚北极环境中3种异产植物高山槟榔、长柔毛槟榔和普通槟榔的生殖资源投入及其后果。资源投资（干物质，氮和磷）估计为生殖努力，RE，和结果的相对体细胞成本的繁殖，RSC，并减少繁殖后的生存和繁殖。相对生殖分配从0.2（N & P在大株高山山杨中）到0.7（干物质在小株长毛山杨中）不等。
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) (...)
