- Abstract
The occurrence of the pod weed, Halidrys siliquosa, is recorded for the first time on the Portuguese coast. Several specimens of this brown algae were observed attached to the rocky surface in tide pools at 41º44′10″N 8º52′34″W, extending southward its previously known geographical distribution. The observed shift is inconsistent with general predictions of species migrations under warming climate conditions, which anticipate poleward shifts rather than southern expansions. Although more data will be required to undoubtedly uncover its cause, the recently observed range expansion raises important questions about the generalization of the previously stated biogeographic rules.
