• Variation in the trophic niches of skates and sharks in the Celtic Sea

  Endang Species Res 61:esr01545 (2026)

  Elasmobranchs often have common food resources, but rapid changes in trophic niche partitioning may occur in response to new environmental conditions resulting from climate change. We examined the…

• Case report: disseminated hemangiosarcoma in a neotropical freshwater stingray Potamotrygon sp.

  Dis Aquat Org

  Few reports describe neoplasia in elasmobranchs, and no prior cases of hemangiosarcoma have been documented. This report describes disseminated hemangiosarcoma in a zoo-housed neotropical river…

• Decadal patterns in ship-strike scarring of whale sharks Rhincodon typus at Ningaloo Marine Park, Western Australia

  Endang Species Res

  Ship-strikes are a major threat to whale sharks Rhincodon typus , but their frequency is difficult to estimate because lethal collisions are rarely reported and non-fatal events must be inferred from…

• Acoustic telemetry reveals cross-border movements and conservation opportunities for reef manta rays Mobula alfredi in southern Africa

  Endang Species Res 60:esr01527 (2026)

  Reef manta rays Mobula alfredi occur across a range of protected and unprotected coastal habitats in the Southwest Indian Ocean, yet their movement ecology remains poorly understood in this region. In…

  Mar Ecol Prog Ser 678:95-107 (2021)

  No-take marine protected areas (MPAs) can provide spatial refuge for species throughout all or part of their life cycles. Cabo Pulmo National Park (CPNP) is a no-take MPA located on the south-east…
