Abstract Skates (class Chondrichthyes; subclass Elasmobranchii; order Rajiformes; family
Rajidae) comprise one quarter of extant chondrichthyans, yet have received little attention in …

Otolith microchemistry provides valuable information about the environmental history of
individual fish, but few studies have considered the influence of population or stock on life …

Understanding migration patterns and habitat use is of great importance for management
and conservation of marine living resources. The chemical composition of otoliths is …

Intraspecific trait variation may result from “carryover effects” of variability of environments
experienced at an earlier life stage. This phenomenon is particularly relevant in partially …

Partial migration is a widespread phenomenon in animals, whereby multiple groups follow
different migration behaviors (ie contingents) within a single population. Fishes exhibit …

The southern New England–mid-Atlantic (SNE–MA) stock of winter flounder
(Pseudopleuronectes americanus) collapsed in the 1990s without discernable recovery to …

As ecosystems change, understanding the consequences for fish population dynamics and
habitat use is essential for resource management. Using white perch (Morone americana) …

Life-cycle diversity is the existence of alternative strategies among coexisting individuals
within the same population and is an important factor in the structuring and connectivity of …

Migrations regulate population structure, which can play an important role in conferring
