Interesting Species

The following article contains two records apparently new to Vancouver Island, notes concerning two species rare in collections from the island and remarks concerning the status of Leptura soror LeConte.Holopleura murginata LeC. A single male, taken on Mount Tzouhalem, Duncan, Vancouver Island, on May 21, 1947, by R. L. Fiddick apparently provides the first record for the island. This interesting species was called to my attention by G. Stace Smith of Creston to whom it was originally sent for determination. The only other British Columbia record, published by H. B. Leech (1945) is based on a single specimen beaten from a Douglas fir at Arrowhead, B.C. by G. Slade on May 10, 1945.

Three new genera and six new species from Vancouver Island, British Columbia, are described: Sensiphorura marshalli gen. et sp.nov. (Pachytullbergiinae), Granuliphorura obtusochaeta gen. et sp.nov., Chaetophorura vancouverica gen. et sp.nov., Mesaphorura pacifica sp.nov., Mesaphorura macrochaeta sp.nov. (Tullbergiinae), and Onychiurus eisi sp.nov. (Onychiurinae). The status of the subfamily Pachytullbergiinae is discussed and all described species are briefly synecologically characterized.

AbstractThe cave-living and monobasic fungus gnat genusSpeoleptaEdwards is reviewed with a description of the first Nearctic species,Speolepta vockerothisp. nov., from Canada (caves in Ontario and British Columbia) and the United States (Alaska). Its morphology, life history, and biology are documented and compared with the single European speciesSpeolepta leptogaster(Winnertz). A further new species,Speolepta orientalissp.nov., is described based on a single male from northern Vietnam, representing the first record of this genus from the Oriental Region.

Conservation Evaluation

In Canada, Psilocarphus elatior occurs in British Columbia, Alberta and Saskatchewan. This paper examines the status of the Pacific populations located on southeastern Vancouver Island in southwestern British Columbia. The Pacific population consists of 12 recorded sites of which only five have been confirmed since 1993. In British Columbia, P. elatior is associated with dried beds of vernal pools and other open, moist depressions at lower elevations. In British Columbia, P. elatior populations occur in large numbers at only two of the seven locations.

Larvae of the nematode Salvelinema walkeri (Ekbaum, 1935) and metacercariae of the trematode Crepidostomum metoecus (Braun, 1900) are recorded for the first time from the amphipod Ramellogammarus vancouverensis Bousfield, 1979 (Amphipoda: Gammaridae).The infected amphipods were collected from De Mamiel Creek, southwestern Vancouver Island, British Columbia. Brief descriptions are given of both parasites, which as adults live in salmonid fishes. This report provides the first record of an intermediate host for S. walkeri, a swim-bladder parasite of salmonids of the Pacific region of North America, and of an intermediate host of a Crepidostomum species in the Pacific region of Canada.

The 27-year response of understory vegetation in a 51-year-old Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) forest to thinning and N fertilization treatments was examined in a silviculture experiment at Shawnigan Lake on southern Vancouver Island of British Columbia. The experiment was a two-way factorial design with three levels for each of thinning and N fertilization. No significant treatment effects on the number of either vascular or nonvascular species were detected. This was also true for the covers of the majority of understory species except salal (Gaultheria shallon Pursh) and Oregon beaked moss (Kindbergia oregana (Sull.) Ochyra). Heavy thinning led to high salal and Oregon beaked moss cover, whereas heavy fertilization resulted in lower cover of salal but had no effect on the cover of Oregon beaked moss. Although thinning had a marginal effect on the cover of canopy trees 27 years after treatment, the cover of the canopy trees had only minimal effects on understory vegetation. Conversely, no adverse effect of understory vegetation on canopy trees was found. This study suggested that after 27 years thinning and fertilization had little effect on understory vegetation whether in terms of species richness or vegetation cover. An effective way to conserve species diversity is to protect specific substrate types, e.g., tree trunks, stumps, and coarse woody debris. A commercial thinning was recommended to reduce the time of stem exclusion in similar type of forests.
