Schistidium relictum is described as a new northwest North American and Siberian species of moss. Important distinguishing characters include dull, nearly black plants, with stems densely and evenly foliated, weakly spreading leaves that usually lack awns, and the mostly 1-stratose distal leaf laminae with 2(–3) -stratose margins. The species has a remarkable disjunct distribution pattern with most of the sites where it has been found having been unglaciated during the Pleistocene glaciations. It is restricted to areas with occurrence of calcareous bedrock, especially limestones. It appears to be rather isolated genetically based on molecular studies of total ITS. It is sister to the large clade, ‘Apocarpum’, which consists of species which probably embody its closest known extant relatives.

One hundred mosses and seven liverworts are reported from the Cypress Hills of southwestern Alberta and southeastern Saskatchewan. Included are 11 bryophytes not previously reported from Saskatchewan and 6 new to Alberta. Of special interest was the discovery of Scapania carinthiaca, known previously from two North American stations and a few in Europe and Siberia. Also interesting was the collection of Dicranum drummondii and Mnium drummondii, both of which are seldom encountered and are restricted to a central North American distribution pattern. Chromosome counts were made from material of Atrichum undulatum var. altecristatum (n = 7), Atrichum selwynii (n = 7), and Plagiothecium turfaceum (n = 11). The ecology and elements of the area are discussed. A montane element of 9.1% was found to exist in the moss flora.

Purpose The original Connected Speech Test (CST; Cox et al., 1987) is a well-regarded and often utilized speech perception test. The aim of this study was to develop a new version of the CST using a neutral North American accent and to assess the use of this updated CST on participants with normal hearing. Method A female English speaker was recruited to read the original CST passages, which were recorded as the new CST stimuli. A study was designed to assess the newly recorded CST passages' equivalence and conduct normalization. The study included 19 Western University students (11 females and eight males) with normal hearing and with English as a first language. Results Raw scores for the 48 tested passages were converted to rationalized arcsine units, and average passage scores more than 1 rationalized arcsine unit standard deviation from the mean were excluded. The internal reliability of the 32 remaining passages was assessed, and the two-way random effects intraclass correlation was .944. Conclusion The aim of our study was to create new CST stimuli with a more general North American accent in order to minimize accent effects on the speech perception scores. The study resulted in 32 passages of equivalent difficulty for listeners with normal hearing.
