Macroinvertebrate community diversity and habitat quality relationships along a large river from targeted eDNA metabarcode assays

Environmental DNA, 2020
Species compositions and diversity levels of aquatic macroinvertebrate communities provide important indicators of ecosystem health. However, such community analyses typically are limited by time and effort of sampling, sorting, and identifications, as ...

When Imagery and Physical Sampling Work Together: Toward an Integrative Methodology of Deep-Sea Image-Based Megafauna Identification

Frontiers in Marine Science, 2021
Imagery has become a key tool for assessing deep-sea megafaunal biodiversity, historically based on physical sampling using fishing gears. Image datasets provide quantitative and repeatable estimates, small-scale spatial patterns and habitat descriptions.

How differences in the settling behaviour of moths (Lepidoptera) may contribute to sampling bias when using automated light traps

European Journal of Entomology, 2016
Quantitative community-wide moth surveys frequently employ flight-interception traps equipped with UV-light emitting sources as attractants. It has long been known that moth species differ in their responsiveness to light traps.

Estimating Deep-Sea Fish Population Density From the Odour Extension Area: A Theoretical Basis and Comparison With the Conventional Methods

Frontiers in Marine Science, 2022
Accurately estimating the population density of deep-sea fish with a baited camera system has long been a significant challenge. Although several theoretical models have been developed using the first arrival time of an individual fish or time-varying ...
