Molecular phylogenetic markers used to be ubiquitously obtained by Sanger sequencing, while recently, next generation sequencing (NGS) approaches have become popular alternatives. In this study, a pipeline utilizing Oxford Nanopore Technologies (ONT) amplicon sequencing (amplicon‐seq) was examined as an alternative to Sanger sequencing, with nine loci [11 polymerase chain reaction (PCR) products], in Aeschynanthus (Gesneriacea...
Land use change threatens global biodiversity and compromises ecosystem functions, including pollination and food production. Reduced taxonomic α‐diversity is often reported under land use change, yet the impacts could be different at larger spatial scales (i.e., γ‐diversity), either due to reduced β‐diversity amplifying diversity loss or increased β‐diversity dampening diversity loss. Additionally, studies often focus on taxo...

Wildfire smoke impacts lake ecosystemsNARA Subscribed
Wildfire activity is increasing globally. The resulting smoke plumes can travel hundreds to thousands of kilometers, reflecting or scattering sunlight and depositing particles within ecosystems. Several key physical, chemical, and biological processes in lakes are controlled by factors affected by smoke. The spatial and temporal scales of lake exposure to smoke are extensive and under‐recognized. We introduce the concept of th...
Are novel or locally adapted pathogens more devastating and why? Resolving opposing hypothesesNARA Subscribed
There is a rich literature highlighting that pathogens are generally better adapted to infect local than novel hosts, and a separate seemingly contradictory literature indicating that novel pathogens pose the greatest threat to biodiversity and public health. Here, using Batrachochytrium dendrobatidis , the fungus associated with worldwide amphibian declines, we test the hypothesis that there is enough variance in “novel” (qua...
Internal phosphorus loading alters nutrient limitation and contributes to cyanobacterial blooms in a polymictic lakeNARA Subscribed
Clear Lake, a medium-sized hypereutrophic, polymictic lake in northern California, has had recurring harmful cyanobacteria blooms (HCBs) for over a century despite reductions in external phosphorus (P) loadings. Internal P loading can alter nutrient availability and limitation supporting HCBs but is rarely quantified or compared with external loads. We have quantified external P loads from 2019 to 2021 for the three main tribu...
Transitional circulation patterns from full ice cover to ice-off in a seasonally ice-covered lakeNARA Subscribed
There is consensus that under-ice circulation presents multiple phases through the winter, and that different mechanisms dominate each period. In this work, measurements of temperature, water velocity, conductivity, and dissolved oxygen from Lake Massawippi, Quebec, Canada, obtained during the ice-covered season in 2019, were used to characterize the time scales of different winter regimes and transitions among dominating circ...
Re‐imagining the precautionary approach to make collaborative fisheries management inclusive of Indigenous Knowledge SystemsNARA Subscribed
Fisheries science uses quantitative methods to inform management decisions that reflect cultural preferences which, in turn, indirectly influence the states of ecosystems. To date, it has largely supported Eurocentric preferences for the commodification of marine organisms under the tenets of maximum sustainable yield, whereby abundances are intentionally maintained far below their historical baselines despite broader socio‐ec...
