During the ongoing investigation of bambusicolous ascomycetous fungi in Yunnan,China,24 specimens belonging to the family Roussoellaceae were collected and identified based on morphological features and phylogenetic support.Maximum-likelihood(ML) analyses and Bayesian analyses were generated based on the combined data set of ITS,LSU,tef1,and rpb2loci.The phylogenetic analyses revealed four novel lineages in Roussoella s.str.;thus,we introduced four new species viz.,Roussoella multiloculate sp.nov.,R.papillate sp.nov.,R.sinensis sp.nov.,and R.uniloculata sp.nov.Their morphological characters were compared with the known Roussoella taxa,which lack sequence data in the GenBank.Asexual morphs of R.kunmingensis and R.padinae were recorded from dead bamboo culms in China(from the natural substrates) for the first time.Neoroussoella bambusae,Roussoella japanensis,R.nitidula,R.padinae,R.scabrispora,and R.tuberculate were also reported as the first records from China.All new taxa are described and illustrated in detail.Plates are provided for new reports.

The Hengduan Mountains region is a biodiversity hotspot. In this study, we report the karyotypes of 19 species(21 populations) of Asteraceae from this region, 14 of which are reported for the first time. We also examined polyploidy in Asteraceae plants and summarized karyotype data in the literature for 69 congeneric taxa. In these genera, there were five different ploidy levels in the region, though the most dominant was diploid(73.08%). There is no direct evidence that ploidy level and karyotype asymmetry are associated with the distribution of recorded Asteraceae species from the Hengduan Mountains. This suggests that polyploidy(26.92%) may not play an important role in the evolutionary history of these plants, even though, among these genera, the ratio of paleopolyploidy was high(46.15%).

Fungi are an essential component of the ecosystem.They play an integral role in the decomposition of leaf litter and return nutrients to the ecosystem through nutrient cycling.They are considered as the“key players”in leaf litter decomposition,because of their ability to produce a wide range of extracellular enzymes.Time-related changes of fungal communities during leaf litter decomposition have been relatively well-investigated.However,it has not been established how the tree species,tree phylogeny,and leaf litter chemistry influence fungal communities during decomposition.Using direct observations and a culturing approach,this study compiles fungi found in freshly collected leaf litter from five phylogenetically related,native tree species in Taiwan:Celtis formosana(CF),Ficus ampelas(FA),Ficus septica(FS),Macaranga tanarius(MT),and Morus australis(MA).We investigated(i)the effects of tree species(including tree phylogeny)and leaf litter chemistry on fungal community succession,and(ii)specific patterns of fungal succession(including diversity and taxonomic community assembly)on decomposing leaf litter across the selected tree species.We hypothesized that host species and leaf litter chemistry significantly affect fungal community succession.A total of 1325 leaves(CF:275,FA:275,FS:275,MT:275 and MA:225)were collected and 236 fungal taxa were recorded(CF:48,FA:46,FS:64,MT:42 and MA:36).Tree species relationships had variable associations on the fungal communities,as even closely related tree species had strongly differing communities during decomposition.A high number of species were unique to a single tree species and may indicate‘host-specificity’to a particular leaf litter.The overlap of microfungal species in pair wise comparisons of tree species was low(7–16%),and only 1–2%of microfungal species were observed in leaves of all tree species.The percentage of occurrences of fungal communities using Hierarchical Cluster Analyses(HCA)showed that there were at least four succession stages in each tree species durin

Microorganisms experience intra-and inter-species interactions in the soil,and how these interactions affect the production of microbial volatile organic compounds(VOCs)is still not well-known.Here we evaluated the production and activity of microbial VOCs as driven by bacterial intra-species community interactions.We set up bacterial communities of increasing biodiversity out of 1–4 strains each of the Gram-positive Bacillus and Gram-negative Pseudomonas genera.We evaluated the ability of each community to provide two VOCmediated services,pathogen suppression and plant-growth promotion and then correlated these services to the production of VOCs by each community.The results showed that an increase in community richness from 1 to 4 strains of both genera increased VOC-mediated pathogen suppression and plant-growth promotion on agar medium and in the soil,which was positively correlated with the production of pathogen suppressing and plant growth-promoting VOCs.Pseudomonas strains maintained while Bacillus strains reduced community productivity with an increase in community richness and produced eight novel VOCs compared with the monocultures.These results revealed that intra-species interactions may vary between Gram-negative and Gram-positive species but improved VOC-mediated functioning with respect to pathogen suppression and plant-growth promotion by affecting the amount and diversity of produced VOCs potentially affecting plant disease outcomes.

Physiological adaptation of tree shrews(Tupaia belangeri)to changing environmental temperature has been re-ported in detail.However,the T.belangeri origin(mainland or island),population history,and adaptation to histor-ical climate change remain largely unknown or controversial.Here,for theﬁrst time,we sequenced the simpliﬁed genome of 134 T.belangeri individuals from 12 populations in China and further resequenced one individual from each population.Using population genomic approaches,weﬁrst observed considerable genetic variation in T.be-langeri.Moreover,T.belangeri populations formed obvious genetic structure and reﬂected different demographic histories;they generally exhibited high genetic diversity,although the isolated populations had relatively low ge-netic diversity.The results presented in this study indicate that T.b.modesta and T.b.tonquinia were separated recently and with a similar population dynamics.Second,physical barriers rather than distance were the driving factors of divergence,and environmental heterogeneity may play an important role in genetic differentiation in T.belangeri.Moreover,our analyses highlight the role of historical global climates in the T.belangeri population dynamics and indicate that the decrease of the T.belangeri population size may be due to the low temperature.Finally,we identiﬁed the olfaction-associated adaptive genes between different altitude populations and found that olfactory-related genes of high-altitude populations were selectively eliminated.Our study provides demographic history knowledge of T.belangeri;their adaption history offers new insights into their evolution and adaptation,and provides valuable baseline information for conservation measures.
