Over the past 4 decades there has been a growing concern for conservation status of elasmobranchs (sharks and rays). In 2002, first elasmobranch species were added to Appendix II Convention on International Trade in Endangered Species Wild Fauna Flora (CITES). Less than 20 yr later, 39 5 I. Despite concern, effective management remain challenged by lack data population many species, human−wildlife interactions, threats viability, efficacy approaches. We surveyed 100 most frequently published...
Elucidating how mobile ocean predators utilize the pelagic environment is vital to understanding dynamics of oceanic species and ecosystems. Pop-up archival transmitting (PAT) tags have emerged as an important tool describe animal migrations in environments where direct observation not feasible. Available PAT tag data, however, are for most part limited geographic position, swimming depth environmental temperature, making effective behavioral challenging. However, novel analysis approaches...
Abstract 1. An understanding of the vertical movements elasmobranchs across their range is crucial to defining critical habitat use, its overlap with anthropogenic activities and subsequently managing such interactions. 2. In this study, satellite telemetry was used investigate use three oceanic manta rays ( Mobula birostris ) tagged on northern coast Peru. 3. All mantas exhibited patterns reverse diel migration, where were significantly deeper at night than day, as well an overall...
Considering habitat use throughout the whole range of a highly mobile marine species is necessary to understand life history, identify vulnerabilities, and inform effective management. We used satellite tagging data from 128 adult female salmon sharks Lamna ditropis seasonal hotspots activity in an extended California Current region (ECCR; encompassing Large Marine Ecosystem), area far away their well-described primary Alaska Downwelling Region where they have been documented, but whose...
Abstract Large sharks shape ecosystems across their geographic ranges and have become a top research conservation priority. Eastern North Pacific (ENP) white shark ( Carcharodon carcharias ) aggregations off the United States Mexico are well described, but population status is currently uncertain. Population assessments of ENP complicated by migrations international boundaries, vulnerability at aggregation sites, undetermined mortality levels. While protective legislation exists both in...
