Use of an acceleration data logger to measure diel activity patterns in captive whitetip reef sharks,Triaenodon obesus

open access: yesAquatic Living Resources, 2007
Traditional telemetry methods have been used to quantify the horizontal and vertical displacement of marine species, but are unable to identify specific physical activities such as swimming or gliding, resting, foraging, or spawning. We tested the utility of an acceleration data logger to quantify activity patterns of three captive whitetip reef sharks

Fishers' interactions with endangered “rhinorays” in Karimunjawa National Park, and factors influencing willingness to engage in pro‐conservation behavior

open access: yesConservation Science and Practice, Volume 7, Issue 4, April 2025.
Abstract The “rhinorays” (giant guitarfish‐Glaucostegidae and wedgefish‐Rhinidae) are a critically endangered group of “shark‐like rays,” which have experienced steep global population declines in the past decade due to overfishing. Their slow life histories and high market value increase the risk of trade‐driven extinction and lead to trade‐offs ...

Continental‐Scale Assessment of Climate‐Driven Marine Species Range Extensions Using a Decade of Citizen Science Data

open access: yesDiversity and Distributions, Volume 31, Issue 4, April 2025.
ABSTRACT Aim Climate‐driven extensions of species distributions have serious consequences for human wellbeing and ecosystems. The recent growth of citizen science data collection represents an underutilised resource for the early detection of marine species range extensions (i.e., expansion of species' distributions at the poleward edge) that can ...
