Contrasting Responses to Harvesting and Environmental Drivers of Fast and Slow Life History Species. [PDF]
PLoS ONE, 2016 According to their main life history traits, organisms can be arranged in a continuum from fast (species with small body size, short lifespan and high fecundity) to slow (species with opposite characteristics).

Multi-Model Approach on Growth Estimation and Association With Life History Trait for Elasmobranchs
Frontiers in Marine Science, 2021 Age and growth information is essential for stock assessment of fish, and growth model selection may influence the accuracy of stock assessment and subsequent fishery management decision making.

Sharks and their relatives: can their past help predict their future?
Frontiers in Marine Science, 2023 Elasmobranchs (i.e., sharks, skates, and rays) have survived five mass extinction events and changed relatively little throughout their ~450-million-year evolutionary history. Therefore, elasmobranchs may provide critical evolutionary perspectives on how

Dental microwear texture analysis as a tool for dietary discrimination in elasmobranchs
Scientific Reports, 2021 As abundant and widespread predators, elasmobranchs play influential roles in food-web dynamics of marine communities. Clearly, these trophic interactions have significant implications for fisheries management and marine conservation, yet elasmobranch ...

Elasmobranch bycatch in the Italian Adriatic pelagic trawl fishery. [PDF]
PLoS ONE, 2018 Elasmobranchs are among the most threatened long-lived marine species worldwide, and incidental capture is a major source of mortality. The northern central Adriatic Sea, though one of the most overfished basins of the Mediterranean Sea, supports a very ...

Quantitative assessment of inner ear variation in elasmobranchs
Scientific Reports, 2023 Considerable diversity has been documented in most sensory systems of elasmobranchs (sharks, rays, and skates); however, relatively little is known about morphological variation in the auditory system of these fishes.
