DOI: 10.1007/s10641-020-01021-3
Abstract: Different techniques have been employed for fish surveys in freshwater impoundments, however, despite the increasing applicability of underwater video systems for fish sampling in different aquatic ecosystems, such technology has not been tested in reservoirs.… read more here.

DOI: 10.1016/j.aaf.2020.03.003
Abstract: Abstract Captive propagation and translocation are becoming vital components of conservation and management strategies for Eastern hellbender (Cryptobranchus a. alleganiensis) populations. Zoos, aquaria, universities, and state and federal agencies are concomitantly collaborating on the protection,… read more here.

DOI: 10.1017/s0376892917000480
Abstract: SUMMARY Trawling activities are considered to be one of the main sources of disturbance to the seabed worldwide. We aimed to disentangle the dominance of environmental variations and trawling intensity in order to explain the… read more here.

DOI: 10.1109/joe.2021.3076274
Abstract: We study the transmission of high-quality video underwater. The underwater acoustic medium pathloss attenuation depends not only on transmission distance but also on the frequency occupied by the signal, where lower frequencies have lower attenuation… read more here.

DOI: 10.1371/journal.pone.0228524
Abstract: Nester abundance is a key measure of the performance of the world’s largest green turtle rookery at Raine Island, Australia, and has been estimated by mark-resight counts since 1984. Nesters are first marked by painting… read more here.

DOI: 10.1371/journal.pone.0244154
Abstract: Baited remote underwater video stations (BRUVS) are increasingly being used to evaluate and monitor reef communities. Many BRUVS studies compare multiple sites sampled at single time points that may differ from the sampling time of… read more here.

Optimising sampling of fish assemblages on intertidal reefs using remote underwater video
Sign Up to like & getrecommendations! Published in 2023 at "PeerJ"
DOI: 10.7717/peerj.15426
Abstract: Background Assessing fish assemblages in subtidal and intertidal habitats is challenging due to the structural complexity of many of these systems. Trapping and collecting are regarded as optimal ways to sample these assemblages, but this… read more here.
