Journal of Fish Biology, EarlyView.Abstract Increasing evidence supports associations between various elasmobranch species and estuarine habitats, particularly during early life stages. However, with substantial knowledge gaps surrounding spatial habitat use and trophic ecology of estuary‐associated species in Australia, we cannot reliably assess the functional importance of these areas

, 2015 BACKGROUND: Industrial fishing has profoundly changed the biological state of oceans and seas. While the direct impacts of overfishing on target stocks are being increasingly addressed, unwanted bycatch and discarding of non-target species remains a key ...

Elasmobranch ectoparasite communities in Miami, FL
Parasite communities and interactions with their hosts can provide insight into how host species live. Host life history, species, habitat, size, age, and population health can have effects on parasite communities.

Navigating morphometric minefields: Modelling heteroscedasticity in length‐conversion models
Journal of Fish Biology, EarlyView.Abstract A common problem when combining data on species' traits from multiple sources is that researchers often measure the same trait in different ways. For example, the length of a shark can be measured in a straight‐line or over‐the‐body, and for lengths that include the tail (e.g., fork and total lengths), with the tail in ‘stretched’ or ‘natural’

Revealing elasmobranch diversity across the Cretaceous-Paleogene boundary in the Central Tethys (Byala, Bulgaria) [PDF]
Fossil RecordExtensive bulk-sampling of the continuous K-Pg succession at Byala (Central Tethys) provides high-resolution insights into elasmobranch responses to the end-Cretaceous mass extinction of a deep-marine environmental setting. The studied section represents

Repeatability of baited remote underwater video station (BRUVS) results within and between seasons.
PLoS ONE, 2020 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 another site. As BRUVS

Journal of Fish Biology, EarlyView.Abstract Maximum longevity varies widely among marine‐occurring fishes, but the form of its relationship with body size and the contribution of broad environmental gradients remain uncertain. We analysed 757 species, using maximum length as the primary size metric and completed mass only in sensitivity analyses.

DiversityThough a previous study in Sudan confirmed the existence of a living hybrid of an oceanic manta ray (Mobula birostris) and a reef manta ray (M. alfredi), courtship behaviors between the two closely related species have never been documented.

Journal of Fish Biology, EarlyView.Abstract The shortfin mako (Isurus oxyrinchus) is a fast‐swimming pelagic shark of global ecological and socioeconomic importance, yet it is relatively understudied in temperate eastern Australian waters. This study investigated the trophic ecology of mako sharks using stable isotope analysis (SIA) of nitrogen (δ15N), carbon (δ13C) and sulphur (δ34S ...

Digenea and acanthocephala of elasmobranch fishes from the southern coast of Brazil
Memorias do Instituto Oswaldo Cruz, 2001 New records for helminth species recovered from elasmobranch fishes in Brazil are established. Digenean and acanthocephalan parasites of elasmobranch fishes are reported from the southern coast of Brazil: Otodistomum veliporum (Creplin, 1837) Stafford ...
