Population genetic structure and management perspectives for Armeria belgenciencis, a narrow endemic plant from Provence (France) by Alex Baumel, Frédéric Médail, Marianick Juin, Thibault Paquier, Marie Clares, Perrine Laffargue, Hélène Lutard, Lara Dixon, Mathias Pires

“…Despite its recent decline, the genetic diversity of A. belgenciensis was not particularly low compared to the other studied populations or other rare species in this genus. The existence of gene flow between these two populations is likely given their moderate differentiation and the detection of admixture by one of the clustering methods. …”

Biodiversity consequences of long-term active forest restoration in selectively logged tropical rainforests by Nadine Keller, Pascal A. Niklaus, Jaboury Ghazoul, Tobias Marfil, Elia Godoong, Christopher D. Philipson

“…Surprisingly, our findings suggest that active forest restoration promoted the recovery of adult tree species diversity, expressed as Shannon Diversity Index, and in particular promoted rare species. In actively restored plots, the number of adult individuals of tree species that were planted was enhanced, and the density of liana seedlings was reduced, demonstrating that these silvicultural interventions were effective and had long-lasting effects on the forest structure. …”

Phytonanofabrication of iron oxide particles from the Acacia jacquemontii plant and their potential application for the removal of brilliant green and Congo red dye from wastewater by Shreya Patel, Reema Desai, Bhakti Patel, Daoud Ali, Vinars Dawane, Kamlesh Gadhvi, Virendra Kumar Yadav, Nisha Choudhary, Dipak Kumar Sahoo, Ashish Patel

“…In the current investigation, we reported the phyto-assisted formation of iron oxide nanoparticles (IONPs) from a rare species of Acacia (Acacia jacquemontii). First, ethanolic extracts of the stem powder were analyzed by high-performance thin-layer chromatography (HPTLC) for the identification of phytochemicals in the stem sections of Acacia. …”

High‐frequency and long‐term observations of eDNA from imperiled salmonids in a coastal stream: Temporal dynamics, relationships with environmental factors, and comparisons with co... by Ryan T. Searcy, Alexandria B. Boehm, Chloe Weinstock, Christina M. Preston, Scott Jensen, Brent Roman, James M. Birch, Christopher A. Scholin, Kyle S. Van Houtan, Joseph D. Kiernan, Kevan M. Yamahara

“…The objectives of this study were to use autonomous sampling to conduct long‐term, high‐frequency monitoring of the eDNA of native salmonid species in a Californian coastal stream, describe temporal variation of eDNA on multiple scales and identify environmental factors that drive this variation, and evaluate the ability of the eDNA datasets to detect rare species and represent organismal abundance. Using high‐throughput autonomous environmental sample processors (ESPs) and qPCR, we enumerated eDNA concentrations from 674 water samples collected at subdaily intervals over 360 days at a single site. …”

Effects of error, chimera, bias, and GC content on the accuracy of amplicon sequencing by Yujia Qin, Liyou Wu, Qiuting Zhang, Chongqin Wen, Joy D. Van Nostrand, Daliang Ning, Lutgarde Raskin, Ameet Pinto, Jizhong Zhou

“…In addition, comparative analyses based on the mock communities showed that several widely used sequence processing pipelines/methods, including DADA2, Deblur, UCLUST, UNOISE, and UPARSE, had different advantages and disadvantages in artifact removal and rare species detection. These results are important for improving sequencing quality and reliability and developing new algorithms to process targeted amplicon sequences.IMPORTANCEAmplicon sequencing of targeted genes is the predominant approach to estimate the membership and structure of microbial communities. …”

Development of a Tetraplex Digital PCR Assay for the Detection of Invasive Snake Species in Florida, USA by Melissa A. Miller, Melody Bloch, Sergio A. Balaguera‐Reina, Kevin A. Olejniczak, Cynthia A. Fussell Persaud, Ericka E. Helmick, Frank J. Mazzotti, Brian W. Bahder

“…While traditional survey methods that rely on visual detections fail to reliably detect invasive constrictors, environmental DNA (eDNA) has proven to be a promising method for detection of cryptic and rare species across the landscape. To address emerging needs for multispecies detection and monitoring in Florida, we developed the first tetraplex dPCR assay designed for detection of four species of invasive constrictor snakes, including Burmese pythons (Python bivittatus), northern African pythons (P. sebae), boa constrictors (Boa constrictor), and rainbow boas (Epicrates cenchria). …”
