Dental crown morphological variation and heterodonty in carcharhiniform sharks

The Anatomical Record, EarlyView.
Abstract Elasmobranch teeth are highly mineralized structures that constitute the majority of the fossil record for this group. Despite their taxonomic and evolutionary significance, detailed descriptions of dental morphology remain scarce. The order Carcharhiniformes, the most diverse among sharks, comprises 304 valid species that display remarkable ...

Evidence for different shark species feeding on a diminutive right whale and a relative of the beluga in the Early Pliocene of the southern North Sea

Acta Palaeontologica Polonica
Documenting past trophic relationships is crucial to understand deep time changes in the ecology and geographic distribution of large marine predators. Though bite marks on cetacean bones are a useful source of information to assess shark-whale predator ...

Is free trade good for renewable resources? Brander and Taylor redux

Canadian Journal of Economics/Revue canadienne d'économique, EarlyView.
Abstract This paper generalizes the original Brander and Taylor model of open‐access renewable resource use and trade to address three common critiques. First, I introduce heterogeneity across agents in harvesting productivity to smooth out the model's extreme specialization patterns while maintaining its Ricardian structure and tractability. Second, I

‘Sharktober’: tiger shark parturition drives seasonality in shark bite incidents in Hawaiian waters

Frontiers in Marine Science
Shark bite incidents in Hawaiian waters exhibit a significant seasonal pattern, with October experiencing a disproportionate spike in bites despite no corresponding increase in ocean recreational activity. Analysis of 30 years of bite records (1995–2024)
