A Multi‐Method Approach to Assessing Barrier Effectiveness in Preventing the Spread of Invasive Signal Crayfish (Pacifastacus leniusculus)

River Research and Applications, EarlyView.
ABSTRACT Relieving barriers and increasing free flowing rivers is a global imperative to restore habitat connectivity for migratory fish stocks. While reducing river fragmentation will certainly improve biodiversity, the spread of non‐native species throughout a river system may be facilitated as an inadvertent outcome.

Scalable low‐cost seabed landers: the missing link for sustained, integrated, long‐term observations in dynamic shallow seas

Remote Sensing in Ecology and Conservation, EarlyView.
Seabed landers, when equipped with a range of biotic and abiotic sensors, offer a non‐invasive and cost‐effective solution for ecosystem‐scale monitoring of Essential Biodiversity Variables (EBVs) and Essential Ocean Variables (EOVs) in dynamic shallow seas.

Development and Evaluation of a Low‐Cost, Semi‐Automated Camera Trap for Surveying Bumble Bee Communities

Remote Sensing in Ecology and Conservation, EarlyView.
Camera traps are emerging as a useful tool for noninvasive insect monitoring; however, it remains unclear how to lure diurnal insects to traps, how to detect them upon arrival, and how camera‐based methods compare to conventional sampling. We developed a low‐cost, open‐source camera trap to monitor wild bumble bees in agricultural fields. We found that

Testing multiple environmental DNA substrates for detection of the cryptic and Critically Endangered burrowing freshwater crayfish Engaewa pseudoreducta

Environmental DNA
Effective conservation of endangered species depends on knowledge of their distributions, but species detection can often be challenging. An example of this is provided by the Critically Endangered Margaret River burrowing crayfish (Engaewa pseudoreducta)

Using eDNA to Track Microbial and Meiofaunal Communities in the Environment Surrounding Coastal Finfish Aquaculture in Nova Scotia

, 2021
Finfish aquaculture has increased globally in recent years, leading to concerns about effects on the surrounding environment. Traditionally used biological environmental monitoring techniques are often time consuming and expensive, therefore eDNA has ...

Paradigms and Principles for Integrating Nature Technology Data: Challenges, Opportunities, and Next Steps in Real‐World Biodiversity Monitoring

Remote Sensing in Ecology and Conservation, EarlyView.
We propose a set of paradigms (survey design, tip and cue, validation, consilience, interpolation and extrapolation, and data fusion) and prioritize a set of principles (metadata standards, use rights and licensing, scientific rigor, and utility) as the foundations of an actionable framework for nature technology data integration. We then analyze seven
