Animal geolocation with convolution algorithms in Julia and R via Wahoo.jl

Methods in Ecology and Evolution, EarlyView.
Abstract Animal geolocation is the core of movement ecology. In aquatic ecosystems, electronic tagging and tracking technologies, such as passive acoustic telemetry systems and biologging sensors, are widely deployed. However, statistical estimation of individual locations from these datasets can be challenging and computationally expensive.

Benthic habitat mapping in the Olympic Coast National Marine Sanctuary: Classification of side scan sonar data from survey HMPR-108-2002-01: Version I [PDF]

, 2006
In September 2002, side scan sonar was used to image a portion of the sea floor in the northern OCNMS and was mosaiced at 1-meter pixel resolution using 100 kHz data collected at 300-meter range scale.

State‐space models and inference approaches for aquatic animal tracking with passive acoustic telemetry and biologging sensors

Methods in Ecology and Evolution, EarlyView.
Abstract Passive acoustic telemetry systems are widely deployed to track animals in aquatic environments. However, investments in integrative methods of data analysis have remained comparatively limited, with current workflows typically considering individual movements separately from space use, home ranges and residency.

Web GIS Based Benthic Habitat Mapping Update Supports Smart Island Lemukutan

Journal of Applied Geospatial Information
Benthic habitats are important for the quality of life and global climate. Systematic and efficient information is important for the monitoring, mapping, and recording of aquatic bottom habitats, thus providing a habitat database.

A review of autonomous reef monitoring structures (ARMS) for monitoring hard‐bottom benthic biodiversity

Methods in Ecology and Evolution, EarlyView.
Abstract Amid increasing anthropogenic pressures on ecosystems, standardised biodiversity monitoring is critical for assessing biodiversity change. Marine hard‐bottom habitats, though ubiquitous and biodiverse, present challenges for biodiversity monitoring due to their complex structure and limited accessibility. Autonomous reef monitoring structures (

Remote Sensing Reveals Multidecadal Trends in Coral Cover at Heron Reef, Australia

Remote Sensing
Coral reefs are experiencing increasing disturbance regimes. The influence these disturbances have on coral reef health is traditionally captured through field-based monitoring, representing a very small reef area (

Random encounter modelling as a viable method to estimate absolute abundance of reef fish

Methods in Ecology and Evolution, EarlyView.
Abstract Remote underwater video (RUV) surveys are increasingly replacing diver‐based underwater visual censuses (UVCs) in fish ecology studies, especially on coral reefs. However, extracting reliable estimates of abundance or density from video footage is a major challenge, with most studies using a metric of relative abundance, MaxN (maximum number ...

Variation in size and abundance of Caribbean spiny lobster (Panulirus argus) with change in hardbottom habitat

The Owl, 2014
The specific characteristics that make a habitat suitable for an organism vary both between species and between life stages within a single species. Hardbottom habitats in Florida Bay are known as nurseries for a number of commercially and ecologically ...

Biodiversity research requires more motors in air, water and on land

Methods in Ecology and Evolution, EarlyView.
Abstract Human activities have accelerated species extinctions, driving rapid biodiversity decline. Simultaneously, advancements in Artificial Intelligence (AI) and autonomous systems offer transformative potential for biodiversity research. Uncrewed vehicles—drones (aerial systems) and other robots (ground and underwater platforms)—equipped with high ...
