Shark detection and classification with machine learning

Shark detection and classification with machine learning J. Jenrette, Z. Y.-C. Liu, P. Chimote, T. Hastie, E. Fox, F. Ferrettia ABSTRACT: Suitable shark conservation depends on well-informed population assessments. Direct methods such as scientific surveys and fisheries monitoring are adequate for defining population statuses, but species-specific indices of abundance and distribution coming from these sources

Functional and phylogenetic diversity of sharks in the Northeastern Pacific

Functional and phylogenetic diversity of sharks in the Northeastern Pacific

Functional and phylogenetic diversity of sharks in the Northeastern Pacific Zachary A. Siders, Lauren B. Trotta, Fabio P. Caltabellotta, Katherine B. Loesser, Benjamin Baiser, Robert N. M. Ahrens ABSTRACT: AimThe expansive spatial scale of pelagic communities and the difficulty in acquiring pelagic species’ functional traits have stymied an understanding of marine community dynamics. We assembled

DNA barcoding of traded shark fins in Peninsular Malaysia

DNA barcoding of traded shark fins in Peninsular Malaysia Ying Giat Seah, Caroline Kibat, Simon Hew & Benjamin J. Wainwright ABSTRACT: Southeast Asia is a major shark product trade hub, and many of the world’s largest shark product selling markets are located in the region. Malaysia is the second largest importer of shark fins in

Dental pathologies in lamniform and carcharhiniform sharks

Dental pathologies in lamniform and carcharhiniform sharks

Dental pathologies in lamniform and carcharhiniform sharks with comments on the classification and homology of double tooth pathologies in vertebrates Harrison S. Miller​, Haviv M. Avrahami, Lindsay E. Zanno ABSTRACT: Double tooth pathologies are important indicators of trauma, disease, diet, and feeding biomechanics, and are widely documented in mammals. However, diagnosis of double tooth pathologies

An epithelial signalling centre in sharks supports homology of tooth morphogenesis in vertebrates

An epithelial signalling centre in sharks supports homology of tooth morphogenesis in vertebrates

An epithelial signalling centre in sharks supports homology of tooth morphogenesis in vertebrates Alexandre P Thiery, Ariane S Standing, Rory L Cooper, Gareth J Fraser ABSTRACT: Development of tooth shape is regulated by the enamel knot signalling centre, at least in mammals. Fgf signalling regulates differential proliferation between the enamel knot and adjacent dental epithelia

Evaluating the Shark Deterrent Effects of the Novel Exclusion Barrier in Comparison to the Rigorously Tested Sharksafe Barrier Technology

Evaluating the Shark Deterrent Effects of the Novel Exclusion Barrier in Comparison to the Rigorously Tested Sharksafe Barrier Technology

Evaluating the Shark Deterrent Effects of the Novel Exclusion Barrier in Comparison to the Rigorously Tested Sharksafe Barrier Technology Craig P O’Connell, Julia Crews, Andre King, Juliet Gressle ABSTRACT: Although exceedingly rare, shark attacks have a disproportionately large impact on human behavior, often resulting in shark culls. Due to the invasive nature of shark culls,
