Predictive habitat suitability models to aid conservation of elasmobranch diversity in the central Mediterranean Sea [PDF]

open access: yes, 2015
Commercial fisheries have dramatically impacted elasmobranch populations worldwide. With high capture and bycatch rates, the abundance of many species is rapidly declining and around a quarter of the world’s sharks and rays are threatened with extinction.

Population structure, distribution and abundance patterns of the patagonian smoothhound Mustelus schmitti Springer, 1939 (Chondrichthyes, Elasmobranchii, Triakidae) in the rio de La Plata and inner continental shelf , sw Atlantic ocean (34º30'-39º30'S)

open access: yesBrazilian Journal of Oceanography, 2007
A total number of 4824 Mustelus schmitti was sampled. Females ranged from 25 to 93 cm in spring and from 28 to 90 cm in summer. Males ranged from 34 to 82 and from 28 to 77 cm, respectively.

Consumption to biomass (Q/B) ratio and estimates of Q/B-predictor parameters for Caribbean fishes [PDF]

open access: yes, 2002
Estimates of the Q/B ratio and parameters of equations to 'predict' Q/B values for 116 fish stocks in the Gulf of Salamanca, Colombia are presented. A compilation of these estimates available for Caribbean Sea fishes (264 stocks) is also provided for ...

Overfishing and the replacement of demersal finfish by shellfish: an example from the English Channel. [PDF]

open access: yes, 2013
The worldwide depletion of major fish stocks through intensive industrial fishing is thought to have profoundly altered the trophic structure of marine ecosystems.

Preliminary study on age, growth and reproduction of Mustelus mustelus (Elasmobranchii: Carcharhiniformes: Triakidae) inhabiting the Gulf of Iskenderun, north-eastern Mediterranean Sea [PDF]

open access: yesActa Ichthyologica et Piscatoria, 2018
Background. Shark populations within the eastern Mediterranean are declining due to overfishing. Unfortunately, our knowledge on the biology of sharks and specifically dogfishes within eastern Mediterranean is extremely limited due to the lack of ...

Diversification of the Neoselachii (Chondrichthyes) during the Jurassic and Cretaceous [PDF]

open access: yes, 2006
The Neoselachii are a monophyletic group including all of the extant sharks and rays. They underwent rapid diversification throughout the Jurassic and Cretaceous, going from low-diversity assemblages of members of extinct orders in the Late Triassic to ...

Assessment of a Social Media‐Based Method for Determining Raptor Diet

open access: yesEcology and Evolution, Volume 15, Issue 6, June 2025.
This study mined social media as a citizen science method to reduce the time burden and biases associated with recording accurate diet information for predators. In total, 1985 prey observations were recorded of two Australian coastal raptors and were used to produce diet profiles that were compared by region, social media platform, and against other ...

The value of conditional prediction: Can retained species help predict unknown discards in commercial fisheries?

open access: yesJournal of Applied Ecology, Volume 62, Issue 6, Page 1392-1405, June 2025.
Due to their higher performance and reliability, we consider SSDMs valuable for modelling unobserved discards and advise caution when using conditional joint prediction for continuous response variables such as biomass, especially when overdispersion is likely.

Identification and phylogenetic inferences on stocks of sharks affected by the fishing industry off the Northern coast of Brazil [PDF]

open access: yes, 2009
The ongoing decline in abundance and diversity of shark stocks, primarily due to uncontrolled fishery exploitation, is a worldwide problem. An additional problem for the development of conservation and management programmes is the identification of ...
