Baleen Whale Occurrence in the Waters Off Virginia and North Carolina, U.S.A. From 2001 to 2019NARA Subscribed
Eighteen years of visual survey and strandings data were used to describe baleen whale occurrence along the continental shelf of Virginia and North Carolina, U.S.A. This region experiences heavy anthropogenic use, which poses risks for mortality and injury to baleen whales. Between 2001 and 2019, six species of baleen whales were recorded, and whales occurred year‐round. The total number of (on‐ and off‐effort) sightings and s...
Individual identification of bony fishes using unique body markings: Implications and applicationsNARA Subscribed
The natural variation in animal body markings, such as spots, stripes and blotches, offers a powerful tool for researchers, conservationists, citizen scientists and resource managers to distinguish specific individuals within species. By building libraries of photo‐identified individuals, we can track and differentiate individuals over time and space, thereby non‐invasively and often cost‐effectively studying species' biology...
Structural and developmental insights into the muscles involved in lionfish ( Pterois spp.) vocalisationsNARA Subscribed
Vocal signalling is an important mode of communication in fishes. The two species of lionfish in the Pterois complex, the Indo‐Pacific lionfish ( Pterois volitans) and the red lionfish ( Pterois miles ), are both known to produce different types of sounds with sonic muscles attached to the swimbladder. However, the specific mechanism and the functions of these vocalisations in these invasive species are still unknown. We used...
Predation can shape the distribution and abundance of animals in an environment, with a major source of predation in some systems now coming from humans. However, measuring the influence of human activities on animal behaviour across large geographic ranges can prove challenging. Here we use a citizen science approach to assess relationships between human hunting pressure and invasive lionfish abundance and behaviour across th...
Lionfish (Pterois volitans) do not show directional preferences for ambient underwater soundscapes during diurnal hoursNARA Subscribed
Sound is a valuable cue in the marine environment that can inform animals about habitat location and community composition. Indeed, sound is often used for orientation and navigation by larval reef fishes during settlement. However, despite sound’s role in the early life of reef fishes, whether post-settlement reef fishes use ambient soundscapes to inform their movement decisions remains less clear. In an in-situ playback expe...
The Influence of Biological Maturity on Dynamic Force–Time Variables and Vaulting Performance in Young Female GymnastsNARA Subscribed
Purpose This cross-sectional study investigated dynamic force–time variables and vaulting performance in young female gymnasts of different maturity status. Methods 120 gymnasts aged 5–14 years were sub-divided into maturity groupings using percent of predicted adult height (%PAH) attained. Participants performed three jumping protocols, the squat jump (SJ), countermovement jump (CMJ) and drop jump (DJ), before completing stra...
Metabolic rhythms in flowing waters: An approach for classifying river productivity regimesNARA Subscribed
Although seasonal patterns of ecosystem productivity have been extensively described and analyzed with respect to their primary forcings in terrestrial and marine systems, comparatively little is known about these same processes in rivers. However, it is now possible to perform a large‐scale synthesis on the patterns and drivers of river productivity regimes because of the recent sensor advances allowing for near‐continuous es...
