Incompatibility Reactions

Phellinus weirii is a heterothallic basidiomycete lacking clamp connections. Compatible pairings of single-spore isolates have a changed colony morphology, faster growth, and fewer nuclei per cell than the single-spore isolates alone. Compatible pairings occasionally form basidiocarps in culture. Single-spore isolates from different fruiting bodies are sexually compatible; most single-spore isolates from the same fruiting body are incompatible. Vegetative incompatibility is manifested by a line of demarcation formed when two dissimilar heterokaryotic isolates meet. Line formation is a sensitive indicator of genetic differences between heterokaryons or between heterokaryons and homokaryons.

Combined Data

The genus Bunodera Railliet, 1896 is represented by five freshwater species: the holarctic B. luciopercae (Müller, 1776) in percids; the endemic North American B. sacculata VanCleave and Mueller, 1932 in percids; B. eucaliae (Miller, 1936) and B. inconstans (Lasee, Font and Sutherland, 1988) in freshwater sticklebacks; and the trans-Pacific B. mediovitellata Tsimbaliuk and Roytman, 1966 in the threespine stickleback (Gasterosteus aculeatus L., 1758). Partial sequences of the 28S ribosomal RNA gene were combined with morphological data for a phylogenetic analysis of Bunodera spp. Parsimony analysis of the combined data yielded a tree (consistency index = 0.84) that supports the following resolution: ((((B. luciopercae(((B. sacculata((B. mediovitellata(B. eucaliae + B. inconstans)))). The basal position of B. luciopercae is consistent with its holarctic distribution and a basal percid as its main host. The relatively basal positions of two typical perch parasites and the association of a more derived clade (B. mediovitellata + B. eucaliae + B. inconstans) with sticklebacks indicate host shifting from percids to sticklebacks. The sister relationships and North American endemicity of the two most derived species, B. eucaliae and B. inconstans, are also consistent with the more derived position of their typical host, the freshwater brook stickleback (Culaea inconstans (Kirtland, 1841)).

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.
