And all the abiotic samples were less than 15.

所有样品均少于15个。

This is the digital journal where they're constructing their models based on this abiotic data to show what they expect to see.

利用这个电子日志， 他们能根据这些数据这里，他们正用定性的陈述 来支持他们的模。

While both forestry and agriculture are frequently aimed at the harvest of goods, these two management styles take vastly different approaches since the ecosystem being managed have vastly different biotic and abiotic components.

虽然林业和农业通常都以收获目标，但这两种管理方式采取了截然不同的方法，因所管理的态系统具有截然不同的和组成部分。

This enables ecologists to measure the biodiversity of an area, record data on abiotic factors, and even get a good estimate of the complexity of a local ecosystem in comparison to other sampling sites.

这使态学家能够测量一个地区的多样性，记录因素的数据，甚至与其他采样点相比，对当地态系统的复杂性有一个很好的估计。
