For those following the Whale Lab at the University of Victoria, and
colleagues interested in whale geography, a couple of new publications

First record of the marine mysid Hippacanthomysis platypoda Murano &
Chess, 1987 in coastal waters of British Columbia, Canada

Mysids are key components of marine ecosystems, and changes in abundance
or range may be indicative of a wider ecological condition. We report for
the first time the collection of the mysid Hippacanthomysis
platypodaMurano & Chess, 1987, previously known from California, in
samples taken at a study site on the west coast of Vancouver Island,
British Columbia, Canada. The record may represent a growth in population
number, or perhaps a range extension northward. Drivers for this increased
recruitment or expansion may include an opening of niche space following
reduction of sympatric species by predation and ocean warming from El Niño
effect.



Whale geography -Acoustics, biogeography and whales

Typically, organism-based biogeographic studies consider distribution and
abundance over time on various scales. However, to be comprehensive,
factors of environment and habitat, energetics, morphology, and population
dynamics should also be included. In addition, these studies should
consider not only the spatial extent that an individual or species
occupies or can roam within, but also the space over which an animal can
extract and interpret information, a less well-defined element of niche
space which largely shapes its movements or distribution. Understanding
the processes that inform patterns of species distribution, both intrinsic
and external to the animal, is key to understanding a species’ ecology.
Here, we consider the biogeography of whales, given these ideas, with a
particular focus on the acoustical components of their biology and
landscape. Cetaceans use of sound to communicate, navigate and forage, and
so interpret the soundscape, is a central consideration. It has important
implications in a changing ambient environment and will increasingly
influence species’ survival.
