1. The species showed no significant decline in fecundity. 该物种的繁殖力没有明显下降。
2. To be a successful replicator, there are three key characteristics: longevity, fecundity and fidelity. 要成为一个成功的复制因子，有三个关键特征：寿命、繁殖能力和准确度。
3. Plant species dependent solely on seeds for survival or dispersal are obviously more vulnerable to any decrease in plant fecundity that occurs. 显然，仅依靠种子生存或传播的植物物种更容易受到植物繁殖力下降的影响。
4. The question of whether the decrease in plant fecundity caused by the spraying of pesticides actually causes a decline in the overall population of flowering plant species still remains unanswered. 喷洒杀虫剂导致的植物繁殖力下降是否真的会导致开花植物物种总数的下降，这个问题仍然没有答案。
5. Fecundity is the ability to reproduce in large numbers. 生殖力是指大量繁殖的能力。
