Anthropo-niche characterization of Mediterranean cephalopods with trace elements and isotopic niches

Marine Pollution Bulletin, 2020
Human pressure leaves a mark on coastal ecosystems that can be used to study the ecology of marine species. This study compared the trace elements (TEs) composition and isotopic niche metrics of the squid Loligo vulgaris, the cuttlefish Sepia officinalis and the octopus Octopus vulgaris in the western Mediterranean Sea.

Isotopic niches do not follow the expectations of niche conservatism in the bird genusCinclodes

Journal of Evolutionary Biology, 2022
AbstractPhenotypic traits are expected to be more similar among closely related species than among species that diverged long ago (all else being equal). This pattern, known as phylogenetic niche conservatism, also applies to traits that are important to determine the niche of species.

Isotopic niche mirrors trophic niche in a vertebrate island invader

Oecologia, 2012
Caution for the indiscriminate conversion of the isotopic niche into ecologic niche was recently advised. We tested the utility of the isotopic niche to answer ecological questions on oceanic islands. We compared the isotopic niches of black rats (Rattus rattus) on two islands in the Gulf of California, Mexico: Farrallón de San Ignacio (FSI) and San ...

A niche for isotopic ecology

Frontiers in Ecology and the Environment, 2007
Fifty years ago, GE Hutchinson defined the ecological niche as a hypervolume in n-dimensional space with environmental variables as axes. Ecologists have recently developed renewed interest in the concept, and technological advances now allow us to use stable isotope analyses to quantify these niche dimensions. Analogously, we define the isotopic niche
