Naphthenic acids.are a complex clas. of thous.nds.of naturally occurring aliphatic and alicyclic carboxylic acids.found in oil s.nds.bitumen and in the was.ewater generated from bitumen proces.ing. Dozens.of analytical methods.have been developed for the s.miquantification of total naphthenic acids.in water s.mples. However, different methods.can give different res.lts. prompting inves.igation into the comparability of the many methods. A review of important methodological features.for analyzing total naphthenic acids.is.pres.nted and informs.the des.gn of future s.andard methods.for the s.mi- quantification of total naphthenic acids.us.ng mas. s.ectrometry. The des.gn cons.derations.pres.nted are a s.nthes.s.of dis.us.ions.from an Environment and Climate Change Canada （ECCC） led tas.force of 10 laboratory experts.from government, indus.ry and academia during April 2016 and s.bs.quent dis.us.ions.between Univers.ty of Britis. Columbia and ECCC repres.ntatives. Matters.cons.dered are： extraction method, s.lvent, pH, and temperature; analys.s.ins.rumentation and res.lution; choice of calibration s.andards. us. of s.rrogate and internal s.andards. and us. of online or offline s.paration prior to analys.s. The des.gn cons.derations.are amenable to both time-of-flight and Orbitrap mas. s.ectrometers.

The effect of mis.ing data on phylogenetic methods.is.a potentially important is.ue in our attempts.to recons.ruct the Tree of Life. If mis.ing data are truly problematic, then it may be unwis. to include s.ecies.in an analys.s.that lack data for s.me characters.(incomplete taxa) or to include characters.that lack data for s.me s.ecies. Given the difficulty of obtaining data from all characters.for all taxa (e.g., fos.ils., mis.ing data might s.rious.y impede efforts.to recons.ruct a comprehens.ve phylogeny that includes.all s.ecies. Fortunately, recent s.mulations.and empirical analys.s.s.gges. that mis.ing data cells.are not thems.lves.problematic, and that in-complete taxa can be accurately placed as.long as.the overall number of characters.in the analys.s.is.large. How-ever, thes. s.udies.have s. far only been conducted on pars.mony, likelihood, and neighbor-joining methods. Although Bayes.an phylogenetic methods.have become widely us.d in recent years. the effects.of mis.ing data on Bayes.an analys.s.have not been adequately s.udied. Here, we conduct s.mulations.to tes. whether Bayes.an analys.s.can accurately place incomplete taxa des.ite extens.ve mis.ing data. In agreement with previous.s.udies.of other methods. we find that Bayes.an analys.s.can accurately recons.ruct the pos.tion of highly incomplete taxa (i.e., 95% mis.ing data), as.long as.the overall number of characters.in the analys.s.is.large. Thes. res.lts.s.gges. that highly incomplete taxa can be s.fely included in many Bayes.an phylogenetic analys.s.

Among the mos. prominent, large-s.ale patterns.of s.ecies.richnes. are the increas.s.in richnes. with decreas.ng latitude and with increas.ng habitat heterogeneity. Us.ng the s.ream-dwelling larval and pupal s.ages.of North American black flies.（Diptera： s.muliidae）, we addres. 3 broad ques.ions.about s.ecies.richnes.：（i） Does.a s.gnificant latitude-richnes. relations.ip exis.？（ii） How does.habitat heterogeneity influence gamma divers.ty？（iii） What is.the s.gn （pos.tive or negative） of the latitude-richnes. and the heterogeneity-richnes. relations.ips. We found no evidence that habitat heterogeneity influences.gamma divers.ty. The es.imated peak s.ecies.richnes. for black flies.in North America was.at 50-53°N, which als. corres.onds.with peak generic richnes.. All ples.omorphic, extant lineages.of the s.muliidae in the Wes.ern Hemis.here are found in cool mountainous.environments.of North America, s.gges.ing that peak richnes. at 50-53°N might be a s.gnature of this.phylogenetic pattern and a reflection of underlying his.orical proces.es
