Development and validation of an eDNA protocol for monitoring endemic Asian Spiny Frogs in the Himalayan region of Pakistan
<p>Wildlife monitoring programs are instrumental for the assessment of species, habitat status, and for the management of factors affecting them. This is particularly important for species found in freshwater ecosystems, such as amphibians, as they have higher estimated extinction rates than terrestrial species. We developed and validated two species-specific environmental DNA (eDNA) protocols and applied them in the field to detect the Hazara Torrent Frog (<em>Allopaa hazarensis</em>) and Murree Hills Frog (<em>Nanorana vicina</em>). Additionally, we compared eDNA surveys with visual encounter surveys and estimated site occupancy. eDNA surveys resulted in higher occurrence probabilities for both <em>A. hazarensis</em> and <em>N. vicina</em> than for visual encounter surveys. Detection probability using eDNA was greater for both species, particularly for <em>A. hazarensis</em>. The top-ranked detection model for visual encounter surveys included effects of both year and temperature on both species, and the top-ranked occupancy model included effects of elevation and year. The top-ranked detection model for eDNA data was the null model, and the top-ranked occupancy model included effects of elevation, year, and wetland type. To our knowledge, this is the first time an eDNA survey has been used to monitor amphibian species in the Himalayan region.</p>

FIGURE 3. PC1 vs. PC2 factor scores of the principal components analysis of P. conniffae, P. limbus, P. stictomerus and P. folicola, show P. conniffae and P. limbus clustered together and two species, P. stictomerus and P. folicola, separated well from each other in PC space.

FIGURE 2. Maximum likelihood phylogram based on mitochondrial 16 rRNA showing the phylogenetic position of P. conniffae. Numbers above branches indicate bootstrap support values on right (ML BS ≥ 75) and Bayesian posterior probabilities on left (BI PP ≥ 0.95), respectively; low support values (ML BS <75, BI PP <0.95) are denoted by "-". Recovered species delimitation based on overall significance of results for molecular species delimitation methods ABGD and mPTP using 16S rRNA are shown as grey color rectangles on the right.

Figure 2 in Endemic lineages of spiny frogs demonstrate the biogeographic importance and conservational needs of the Hindu Kush-Himalaya region
Figure 2. Minimum-spanning haplotype networks of Allopaa hazarensis generated for 16S and COI sequence data with the number of used sequences, detected haplotypes, and the level of nucleotide variability. Symbol sizes reflect haplotype frequencies, and a small black line between two haplotypes corresponds to one mutation step. Sequence-IDs are indicated for each haplotype (h1–h8). Map shows the localities from where the respective haplotypes originate.

Figure 1. Bayesian inference (BI; left) and maximum likelihood tree (ML; right) based on concatenated mtDNA and nDNA sequence data (16S + COI + Rag1) of the tribe Paini. Numbers at branch nodes refer to posterior probabilities ≥ 0.9 (BI tree), as well as Felsenstein's bootstrap values ≥ 70% and transfer bootstrap expectation ≥ 0.9 (ML tree). Branches of Allopaa hazarensis are indicated red, while Chrysopaa sternosignata is highlighted green. Species names are followed by voucher number (if available). Coloured shaded boxes indicate subgroups of Nanorana and the new clade (in yellow) with so far unidentified specimens.
