We compare two approaches to designing and analyzing monitoring studies to assess
chronic, local environmental impacts. Intervention Analysis (IA) compares Before and After …

Abstract Before-after-control-impact (BACI) designs are an effective method to evaluate
natural and human-induced perturbations on ecological variables when treatment sites …

Increasingly, environmental managers attempt to incorporate precautionary principles into
decision making. In any quantitative analysis of impacts, precaution is closely related to the …

Caretta caretta (loggerhead sea turtle) nesting activity was recorded daily during three
seasons prior to and two seasons immediately following a beach nourishment …

Mining waste rock dumps (WRDs) are potential sources of pollution, which after rainfall
produce leachate discharges, loaded with acid mining drainage (AMD). The discharges …

The detection of anthropogenic disturbances requires appropriate sampling design and
powerful statistical tests. This study illustrates how simulations of environmental …

Summary The Before‐After Control‐Impact Paired Series (BACIPS) design distinguishes
natural spatial and temporal variability from variation induced by an environmental impact …

Large-scale, unreplicated natural experiments (LUNEs) have a unique power to test
hypotheses at ecologically realistic scales and have delivered insights of great power into …

Since biofilms integrate the environmental effects of water chemistry, along with the physical
and geomorphological characteristics of rivers and lakes, they have been widely applied in …

Scientists and managers often seek to restore degraded systems to more desirable states. A
system might be restored by eliminating a putatively deleterious factor (s) and allowing the …
