“…Each digital quadrat was taken approximately 60 cm above the substratum and captured an area of ~0.25 m 2 . This nested sampling approach is used in a wide range of studies including general ecological descriptions (Riegl et al ., ; Vroom et al ., ); monitoring programmes (Brown et al ., ; McGann and Creary, ); assessment of ecological impacts, such as protection (Dumas et al ., ) and pollution (Hernández‐Delgado et al ., ); community‐level effects of coral bleaching (Tkachenko et al ., ) and disease (Francini‐Filho et al ., ); and development of survey methods (Brown et al ., ; Dumas et al ., ).…”

“…Sublethal doses of military contaminants have been documented in the tissues of fish, marine invertebrates, sea turtles, birds, seagrass, and marine mammals, but without clear physiological consequences. In one of few community‐level studies, multiple indices of coral reef health declined in close proximity to unexploded ordinance at Vieques Island, Puerto Rico, but on the other hand, the same reefs do not exhibit measurable impacts from military activities at larger spatial scales . The effects of contaminants on terrestrial plants are more straightforward, and numerous studies have shown changes to germination and growth rates in a range of species, with the potential to shift community composition at contaminated military sites toward hardy, disturbance‐tolerant vegetation …”

“…In one of few community-level studies, multiple indices of coral reef health declined in close proximity to unexploded ordinance at Vieques Island, Puerto Rico, 47 but on the other hand, the same reefs do not exhibit measurable impacts from military activities at larger spatial scales. 52 The effects of contaminants on terrestrial plants are more straightforward, and numerous studies have shown changes to germination and growth rates in a range of species, with the potential to shift community composition at contaminated military sites toward hardy, disturbance-tolerant vegetation. 53 Immediate, tangible impacts from training activities also have the potential to affect biodiversity, particularly the cratering, wildfires, and disturbance to vegetation and soils associated with live fire training and mechanized maneuvers.…”

“…The number of points to be used per unit area (point density and the unit area being an image frame from a video transect) is crucial to obtaining a robust estimate of percent cover, and initial statistical tests should be performed to establish the point density that will provide adequate precision and accuracy while maximizing efficiency (the time spent identifying substrate types underlying points). Such tests include power analysis [1,4,10], performance curves (graphical examination of standard deviation inflation relative to point density [4,[11][12][13]), bootstrap estimate of bias [13], Pearson's product moment correlations [14], and examination of the interaction term in a two-way ANOVA for transects sampled twice using different point densities [4].…”
