Integrating Sr isotopes, microchemistry, and genetics to reconstruct Salmonidae species and life history

Archaeometry, EarlyView.
Abstract Recent approaches to fisheries research emphasize the importance of the coproduction of knowledge in building resilient and culturally mindful fisheries management frameworks. Despite widespread recognition of the need for Indigenous knowledge and historical reference points as baseline data, archaeological data are rarely included in ...

Combining morphological and molecular data to study past foraminiferal communities from a temperate coastal sediment core

Boreas, EarlyView.
This paper presents the results of a dual approach for assessing fossil benthic foraminiferal communities using both traditional morphology‐based analyses and sedimentary ancient DNA (sedaDNA) metabarcoding. The main objectives are to test the feasibility of sedaDNA analyses to assess foraminiferal biodiversity in temperate shelf sediments (Le Croisic,

Using miniaturized laboratory equipment and DNA barcoding to improve conservation genetics training and identify illegally traded species

Conservation Biology, EarlyView.
Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.

Survival, rarity, and extinction in tropical stony corals

Conservation Biology, EarlyView.
Abstract Many reef‐building tropical corals are becoming rare. We considered the meaning of rarity in corals and highlighted taxa that have reached low abundances in the last few decades. The difficulties of quantifying rarity in the marine environment arise from the sheer scale and 3‐dimensional nature of the biome and the inherent challenges therein ...

Environmental DNA for invasive rat surveillance and biosecurity on islands

Conservation Science and Practice, EarlyView.
We collected aquatic eDNA samples from beach and lake sites on three atoll islands with different invasion statuses before and after a rat eradication operation. Two dozen eDNA samples can confirm with ≥95% probability the presence of invasive rats prior to any management intervention. However, following the eradication operation, neither targeted eDNA

A framework for monitoring ecosystem restoration at landscape scale

Conservation Science and Practice, EarlyView.
The Landscape Restoration Monitoring Framework supports large‐scale ecosystem restoration projects to effectively assess progress towards outcomes. It provides guidance for the selection of indicators to assess change at two different time scales and across a diversity of ecosystem, ecosystem service, and socioeconomic dimensions.

Comparing modern identification methods for wild bees: Metabarcoding and image-based morphological taxonomic assignment.

PLoS ONE
With the decline of bee populations worldwide, studies determining current wild bee distributions and diversity are increasingly important. Wild bee identification is often completed by experienced taxonomists or by genetic analysis.

Limitations to fungal diversity in forest soil during secondary succession

Ecography, EarlyView.
The Bass Becking and Beijerinck theory of the microbial world that ‘everything is everywhere but the environment selects' has provided a basis to test microbial ecological theory for almost a century (Baas Becking 1934). Applying theory to the apparent chaos of the microbial world is arduous, and applying rules that guide our understanding is difficult.

Cyanobacteria in Waterbodies of the Biggest Anthropogenic Agglomeration: Combined DNA Metabarcoding, Microscopy, and Culture Analysis

Phycology
This study describes the results of integrative analysis of cyanobacterial communities in waterbodies of Moscow, Russia. 16S rRNA V3–V4 metabarcoding and light microscopy are implemented to investigate the diversity, abundance, and distribution of ...

Enhanced detection of equine strongyles: Insights from morphological and nemabiome metabarcoding approaches in northern Iran

Equine Veterinary Journal, EarlyView.
Abstract Background Strongyles pose significant health concerns for equids globally. Strongyles, comprising over 60 species, can lead to severe morbidity and mortality, with Strongylus vulgaris posing higher risks due to its migratory behaviour. Routine diagnostic methods, such as faecal egg counts, lack species‐level resolution, while traditional ...
