Summary• This study examined the effects of infection with barley and cereal yellow dwarf viruses (BYDVs) on wild grass species in California, a region in which native perennial bunchgrasses have been largely replaced by exotic annual grasses. We sought to determine whether these widespread viruses compromise the fitness of wild hosts and thus have the potential to influence grassland dynamics. Plant viruses have been long overlooked in ecological studies, and their influence on wild hosts has often been assumed to be minimal.• We examined the short-term and long-term consequences of infection on fieldgrown individuals from 18 different populations of wild California grasses (from seven native and one exotic species).• Barley yellow dwarf virus infection was aggressive in most hosts and markedly impaired host fitness by reducing growth, survivorship, and fecundity.• Previous work indicates that the presence of exotic grasses can more than double BYDV incidence in natives. Given the ubiquity of BYDVs, our results suggest that apparent competition and other virus-mediated processes may influence interactions among native and exotic grasses and potentially contribute to shifts in grassland community composition.
This paper treats the discovery of new species and new records of aleocharine beetles for the province of New Brunswick. We report here 27 species new to science, one new North American record, six new Canadian records, and 29 new provincial records. The following are the new species: Acrotona brachyoptera Klimaszewski & Webster, sp. n., Acrotona sphagnorum Klimaszewski & Webster, sp. n., Atheta (Dimetrota) alphacrenuliventris Klimaszewski & Webster, sp. n., Atheta (Dimetrota) chartersensis Klimaszewski & Webster, sp. n., Atheta (Dimetrota) cranberriensis Klimaszewski & Webster, sp. n., Atheta (Dimetrota) bubo Klimaszewski & Webster, sp. n., Atheta (Dimetrota) mcalpinei Klimaszewski & Webster, sp. n., Atheta (Dimetrota) makepeacei Klimaszewski & Webster, sp. n., Atheta (Dimetrota) giguereae Klimaszewski & Webster, sp. n., Atheta (Dimetrota) petitcapensis Klimaszewski & Webster, sp. n., Atheta (sensu lato) pseudoschistoglossa Klimaszewski & Webster, sp. n., Atheta (sensu lato) sphagnicola Klimaszewski & Webster, sp. n., Atheta (sensu lato) thujae Klimaszewski & Webster, sp. n., Atheta (Pseudota) pseudoklagesi Klimaszewski & Webster, sp. n., Philhygra atypicalis Klimaszewski & Webster, sp. n., Schistoglossa (Schistoglossa) pelletieri Klimaszewski & Webster, sp. n., Thamiaraea corverae Klimaszewski & Webster, sp. n., Thamiaraea claydeni Klimaszewski & Webster, sp. n., Pleurotobia bourdonae Klimaszewski & Webster, sp. n., Pleurotobia brunswickensis Klimaszewski & Webster, sp. n., Agaricomorpha vincenti Klimaszewski & Webster, sp. n., Gyrophaena (Gyrophaena) aldersonae Klimaszewski & Webster, sp. n., Oligota polyporicola Klimaszewski & Webster, sp. n., Oligota sevogle Klimaszewski & Webster, sp. n., Hylota cryptica Klimaszewski & Webster, sp. n., Oxypoda sunpokeana Klimaszewski & Webster, sp. n., and Phloeopora gilbertae Klimaszewski & Webster, sp. n. The spermatheca of Dinaraea curtipenis Klimaszewski & Webster, Dinaraea longipenis Klimaszewski & Webster, and Dinaraea subdepressa (Bernhauer) are illustrated for the first time. Male specimens of Mniusa odelli Klimaszewski & Webster were confirmed and are illustrated. Color habitus images and black and white images of the median lobe of the aedeagus, the spermatheca, and tergite and sternite VIII are provided for all species. New or additional habitat data are provided for most of the species treated in this contribution.
