oughout a catchment or region is used. Once the reference condition has been established, any site suspected of being impacted can be assessed by comparison to the reference sites, and its status determined. The Reference Condition database, once formed, can be used repeatedly.978-1-4613-4705-7978-1-4419-8885-0Flatter 发表于 2025-3-22 05:51:17
s the Reference Condition Approach. This is a significant advancement in biomonitoring because it solves the problem of trying to locate nearby control or reference sites when studying an ecosystem that may be degraded, a problem that bedevils traditional approaches. Rather than using upstream referPhagocytes 发表于 2025-3-22 10:22:03

Dror G. Feitelson,Larry Rudolpheen a particular test site (or set of sites exposed to some common stressor) and the appropriate Reference Condition. Variation in the Reference Condition, rather than being a problem, is a characteristic to be “captured” for the region being studied. We must measured and characterize it before we can assess a test site.不法行为 发表于 2025-3-22 23:16:09
