“…The relationship found between lake water body area and their fluctuations indicates that larger lakes lose more water, since the fluctuations are larger and negative. Given that evaporation is considered the main water output of lakes with no drainage (Brakenridge 1978;Currey and Sack 2009), larger lakes would have more water area available for evaporation (Grasso 1996). This is particularly reasonable for the lakes here studied, since they are shallow lakes with average depth 4.5 m; being only Corona del Inca the one that exceeds this value by almost 8 m (Messager et al 2016).…”

“…Lakes with larger water body area experienced higher negative fluctuations (i.e., area decrease). Many lakes had very small minimum area and were even completely dry in one or more years in the time series, such as Pozuelos (years 1994 and 1995), Salinas Grandes (years 1992, 1994, 1995, 1996, 1998, 2003, 2004and 2017) and Laguna Blanca (years 1996, 2003, 2010and Antofalla (year 1987) of SW Cluster. These last three lakes also showed a trend to increase in water body area throughout the period studied.…”

“…This, in turn, has forced 136 considerable reliance upon local groundwater resources (Danskin, 1998). In contrast, the Amargosa Basin has been historically arid (Belcher, Sweetkind, Hopkins, & Poff, 2019), with 138 intermittent flows in the Amargosa River a residual of rare, large-scale precipitation (Grasso, 1996). Here, SPD persists in ground water seeps (Faunt, Blainey, Hill, & D'Agnese, 2019) that 140 have remained relatively consistent despite overexploitation of local water resources (Robbins, 2017).…”

22The tips in the tree of life serve as foci for conservation and management, yet clear delimitations are masked by inherent variance at the species-population interface. Analyses using thousands of 24 nuclear loci can potentially sort inconsistencies, yet standard categories applied to this parsing are themselves potentially conflicting and/or subjective [e.g., DPS (distinct population 26 segments); DUs (Diagnosable Units-Canada); MUs (management units); SSP (subspecies); Evolutionarily Significant Units (ESUs)]. One potential solution for consistent categorization is 28 to create a comparative framework by accumulating statistical results from independent studies and evaluating congruence among data sets. Our study illustrates this approach in speckled dace 30 (Cyprinidae: Rhinichthys osculus) endemic to two basins (Owens and Amargosa) in the Death Valley ecosystem (DVE). These fish persist in the Mojave Desert as isolated Pleistocene-relicts 32 and are of conservation concern, but lack formal taxonomic descriptions/designations. Doubledigest RAD (ddRAD) methods identified 14,355 SNP loci across 10 populations (N=140). 34Species delimitation analyses [multispecies coalescent (MSC) and unsupervised machine learning (UML)] delineated four putative ESUs. F ST outlier loci (N=106) were juxtaposed to 36 uncover the potential for localized adaptations. We detected one hybrid population that resulted from upstream reconnection of habitat following contemporary pluvial periods, whereas 38 remaining populations represent relics of ancient tectonism within geographically-isolated springs and groundwater-fed streams. Our study offers three salient conclusions: A blueprint for 40 a multi-faceted delimitation of conservation units; a proposed mechanism by which criteria for intraspecific biodiversity can be potentially standardized; and a strong argument for the proactive 42 management of critically-endangered DVE fishes.3
