Collaborative Sampling and Imaging of Phytoplankton Communities by Two Long‐Range Autonomous Underwater Vehicles Using Acoustic Tracking and Messaging

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Collaborative operation of multiple autonomous underwater vehicles (AUVs) can effectively achieve scientific goals that are hard to achieve by independently operated vehicles. Some science payloads are large, expensive, and need to be installed in the vehicle's nose cone. A vehicle can only carry one such payload.

Moorea eDNA project: Wilderlab eDNA protocol v1

open access: yes
This procedure is used to collect eDNA samples from different locations around Mo'orea, French Polynesia; completed by UC Berkeley's Island Sustainability class of 2025 with Dr. Chris Meyer. This protocol includes steps to select sites of interest, collect a water sample, and filter and process the sample.

Control System for the Navigation of the Agricultural Robots: A Review

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Control systems for the navigation of autonomous agricultural robots—particularly those operating in uneven terrain and in the presence of static or dynamic obstacles—have advanced considerably in recent years. As conventional machinery evolves toward increasingly automated systems, the design of reliable navigation controllers has become ...

Estimating shedding and decay rates of environmental nuclear DNA with relation to water temperature and biomass

open access: yesEnvironmental DNA, 2020
Background  Environmental DNA (eDNA) analysis has been recently applied to the surveillance of species distribution and composition in aquatic ecosystems. However, most eDNA studies have used mitochondrial DNA markers, and those using nuclear DNA markers

Development and Assessment of Fluorescent‐Dyed, Preserved Invasive Grass Carp (Ctenopharyngodon idella) Eggs as Surrogates for Live Eggs in Transport and Dispersal Control Experiments

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Invasive species such as grass carp (Ctenopharyngodon idella) pose substantial ecological threats to North American freshwater ecosystems. Understanding their early life stage behavior is critical for management efforts. From spawning to hatching, invasive carp eggs must remain suspended in the water column while drifting downstream for the ...

Potential Impacts of Low Flows on Fish Foodscapes and Production in a Braided River

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Changes in river discharge affect the physical composition and connectivity of habitats which, in turn, may shape the spatial distribution of fish food abundance, accessibility and quality—the ‘foodscape’—of river ecosystems. However, the influence of river flows on fish foodscapes has received very little attention from scientists. We studied

Effect of microplastics on the transport of extracellular DNA in an agricultural soil [PDF]

open access: yesE3S Web of Conferences
The transport of eDNA is one of the key environmental behaviors for its spreading and dispersal. Microplastics (MPs) are widely present in the soil environment and directly affect the environmental behavior of co-coexisting soil pollutants.

A UAV‐based deep learning pipeline for intertidal macrobenthos monitoring: Behavioral and age classification in Tachypleus tridentatus

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
The endangered tri‐spine horseshoe crab (Tachypleus tridentatus), a “living fossil” crucial to coastal ecology and biomedical research, is experiencing severe population declines. Effective conservation requires efficient monitoring, which traditional methods cannot deliver at scale. We develop an integrated UAV deep learning framework tailored to this
