  abstract = {{F}luoroprobes, such as {B}entho{T}orch, offer a relatively rapid in situ method for monitoring benthic algae, provide new opportunities for aquatic ecological research, and enable early warning of algal proliferation in municipal water supplies. {C}urrently, however, {B}entho{T}orch is limited for the measurement of heterogeneous samples, and homogenizing samples is rather difficult. {I}n this study, we compared chlorophyll-a ({C}hl-a) measurements between {B}entho{T}orch and standard laboratory methods to quantify and describe the biomass and biovolume proportion of benthic algae growing on artificial and natural substrates. {W}e used the difference in {C}hl-a measurements between these methods (n = 359) to evaluate the effects of environmental variables. {M}oreover, we used artificial and natural substrates to determine whether either of them reduced variation in {B}entho{T}orch measurements. {T}here was a general concordance in measurements between the two methods, but this agreement was stronger for artificial substrates. {A}rtificial substrates also led to significantly less variation in {B}entho{T}orch readings compared with natural substrates. {T}his may be attributed to the formation of relatively thin algal mats on artificial substrates. {T}o enable early warning of algal proliferation in an aquatic ecosystem, we recommend the use of {B}entho{T}orch and artificial substrates combined with appropriate calibration using standard laboratory methods. {T}he ability of {B}entho{T}orch to produce instantaneous results facilitates replicate collection, which reduces sampling error and increases sampling area on the same day. {D}espite substantial variation in readings on natural substrates, {B}entho{T}orch enables relatively rapid measurements, facilitating easy monitoring of large areas. {T}herefore, {B}entho{T}orch may be worth incorporating into aquatic ecosystem studies, depending on the specific research questions.},
