In the population dynamics of bi-phasic marine invertebrates, fitness one stage in life a cohort affects that following stage. This effect makes prediction fate challenging. We conducted 22 yr monthly survey cockles Cerastoderma edule focussed on juvenile Two types years were distinguished terms longevity: low-mortality group (‘L’) and high-mortality (‘H’). The cockle shell lengths 0 + cohorts ...

Chayote plants (Sechium edule) with monoecious characters require a pollination process. The process requires pollinating agents to increase its productivity, one of which is insects. This research aimed determine the diversity and abundance insects pollinator on chayote plants. Observation used scan sampling method. Pollinator observations were carried out in 3 time periods, morning, afternoon...
