Collections made along the coast of California have revealed the presence of a species of Pseudosphaeroma Chilton, 1909, a genus common in New Zealand coastal waters. The genus is entirely Southern Hemisphere in distribution, and this record reports the introduction of a species of Pseudosphaeroma into the San Francisco and Central Coast region of California, the first reported occurrence of the genus as an invasive taxon, and the first record of the genus from the Northern Hemisphere. The genus is also recorded for the first time from the Galapagos and Argentina.

The late Pleistocene deposits of south-central British Columbia record two major glacial and two major nonglacial periods of deposition. The oldest recognized Pleistocene deposits, called Westwold Sediments, were deposited during a nonglacial interval more than 60 000 years ago. Little information is available on the climate of this period, but permafrost may have been present at one time during final stages of deposition of Westwold Sediments. The latter part of this nonglacial period is probably correlative with the early Wisconsin Substage of the Great Lakes – St. Lawrence Valley area. However, deposition of the Westwold Sediments may have begun during the Sangamon Interglacial.Okanagan Centre Drift is the name applied to sediments deposited during the glaciation that followed deposition of Westwold Sediments. Okanagan Centre Drift is known to be older than 43 800 years BP and probably is older than 51 000. It is considered to correlate with an early Wisconsin glacial period.Bessette Sediments were deposited during the last major nonglacial period, which in south-central British Columbia persisted from at least 43 800 years BP (possibly more than 51 000) to about 19 000 years BP. This episode corresponds to Olympia Interglaciation of the Pacific Coast region and the mid-Wisconsin Substage of the Great Lakes – St. Lawrence Valley area. During parts of Olympia Interglaciation the climate was probably as warm as the present-day climate in the interior of British Columbia. Information from coastal regions indicates that there may have been periods of cooler and moister climate.Kamloops Lake Drift was deposited during the last major glaciation of south-central British Columbia. Ice occupied lowland areas from approximately 19 000 to 10 000 years BP. This period corresponds approximately to the Fraser Glaciation of the Pacific Coast region and the late Wisconsin Substage of central and eastern parts of North America.

It is proposed to offer a series of papers, based primarily on the material collected by Professor E. H. Strickland of the University of Alberta at Edmonton.Chelynia nitida (Cresson). This genus of parasitic bees has over twenty species in North America, the majority from the Pacific Coast region. There are two closely allied species described from females, black with cream-coloured abdominal bands. For some years I have had in my collection a male from Tolland, Colorado, July 1915, at flowers of Frasera, collected by L. A. Kenoyer, determined by me as C. nitida (Cress). I now receive a very similar but distinct male from Professor E. H. Strickland, collected by O. Peck at Beaverlodge, Alberta, July 6, 1931. I conclude that this must be the genuine C. nitida, and the Tolland one the undescribed male of the related C. idahoensis Swenk.

Abstract Small-scale fisheries (SSFs) around the world are increasingly facing pressures from a range of environmental, economic, and social sources. To sustain SSFs, it is imperative to understand how fishing communities adapt to these pressures. In particular, to manage economic risks fishers often catch many different species; diversifying harvest portfolios creates multiple income sources in case one species becomes less abundant, less valuable, or otherwise unavailable. Here, we apply fisheries connectivity network analysis to assess the portfolios and potential adaptive capacity of small-scale fishing communities in the Baja California Peninsula (BCP), Mexico. We found that network metrics like modularity and density varied by region and through time. The Pacific coast region of Baja California displayed increasingly modular fisheries connectivity networks, indicating fisheries landings became increasingly asynchronous with each other and the potential adaptive capacity increased. The remaining three regions of Baja California showed the opposite trend, where the temporal covariance between fisheries increased over time. Overall, this study shows that the potential adaptive capacity of fishing communities varies substantially throughout the BCP, and highlights how fisheries connectivity networks can offer a way to quantify and advance our understanding of adaptive capacity within small-scale fishing communities.
