Fig. 1. Distribution map of known localities for Nymphargus balionotus. Information tags to the left summarize data reported for each locality, including (in order): name of collection site, department/province, number of specimens reported, elevation, and year specimens were collected or observed. Blue circle represents the Río Manduriacu Reserve; red circle marks the type locality; yellow and gray circles represent remaining localities reported in the literature, with the gray (Campamento Chancos) population believed to be a distinct lineage by Cisneros-Heredia and McDiarmid (2006). Note: the "El Tambo" locality in the department of Cauca, Colombia, has been placed as accurately as possible based on available information (see Discussion).

Figure 1 in A NOTE ON SAMPLING CHIRONOMIDS FOR RNA-BASED STUDIES OF NATURAL POPULATIONS THAT RETAINS CRITICAL MORPHOLOGICAL VOUCHERS Abstract
Figure 1. Exemplar RNA extraction QA/QC assessments from the 42 extractions conducted. a) ten extractions analysed using 2% w/v agarose gel electrophoresis: lane 1 contains 1 µL Hyperladder IV (Bioline), lane 2 was intentionally blank, samples are from lanes 3-12; b) exemplar Agilent 2100 Bioanalyzer plot of fragment lengths (x axis) against fluorescence units (y axis). The software automatically attempts to identify the 18S and 28S peaks (labelled below the peak trace in smaller font on an angle) to calculate a RIN.
