“…The search represents all taxa that are likely to have recorded impacts in the literature (see Figure ). The remaining bamboos that were not evaluated in this study are therefore classed as NE—Not Evaluated under the EICAT scheme (although some of these can be considered as NA—No Alien Population according to Canavan et al, ). Of the 135 taxa that were included in the study, we found 65 references which contained details on 20 species for which recorded environmental impacts could be scored using the EICAT scheme.…”

Societal Impact Statement Non‐native species can cause considerable negative impacts in natural ecosystems. Such impacts often are directly due to the fact that these species occur in habitats where they did not evolve. We explored this for bamboos and found that, contrary to the situation in many other plant groups, biogeographic origin was not a strong predictor of the type and severity of environmental impacts caused. We argue that impacts from bamboos are a response to land transformation and disturbance of forest habitats by humans. Therefore, the threats posed by bamboos to highly disturbed forest systems should be the same wherever bamboos are present or planted, and management should adopt similar approaches. Summary Negative environmental impacts can result from the human‐mediated breakdown of biogeographic boundaries that historically shaped species distributions leading to rapid population expansions, that is, from biological invasions. However, the alteration of natural ecosystems by humans has created opportunities for both native and non‐native species to become weedy. We assessed whether origin status (native or non‐native) matters for the type and magnitude of environmental impacts caused by bamboos (Poaceae: Bambusoideae). We used a systematic global literature search and the International Union for Conservation of Nature's (IUCN) Environmental Impact Classification of Alien Taxa (EICAT) scheme as the basis for scoring impacts of bamboo species. We found that the type and severity of recorded impacts were similar in the native and non‐native ranges of weedy bamboos, and that the habitats in which impacts are most often reported (i.e., temperate and tropical forests) were also the same. Origin was not a strong predictor of environmental impacts for bamboos. Rather, impacts are likely to be a response to human‐mediated land transformation and disturbance of forests. Further research on the mechanisms whereby bamboos impact other species is needed to guide management strategies in their native ranges and as input to risk assessments for new introductions and plantings.

“…Many plants (c. 70% in the temperate zone) possess the capacity to reproduce vegetatively via rhizomes and stolons (Klimeš, Klimešova, Hendriks, & van Groenendael, 1997). Such clonal plants, including many invasive exotics (Canavan et al, 2016;Liu et al, 2006;Pyšek, 1997), often dominate terrestrial habitats, such as grasslands, salt marshes, and understoreys of temperate and boreal forests. Clonal plants also appear to increase its abundance in response to global change drivers such as habitat fragmentation (Tomimatsu et al, 2011) and nutrient deposition (Dickson, Mittelbach, Reynolds, & Gross, 2014;Gough et al, 2012), with important consequences for community structure and function.…”

Despite the advantage of plant clonality in patchy environments, studies focusing on genet demography in relation to spatially heterogeneous environments remain scarce. Regeneration of bamboos in forest understoreys after synchronous die‐off provides an opportunity for assessing how they come to proliferate across heterogeneous light environments. In a Japanese forest, we examined genet demography of a population of Sasa kurilensis over a 7‐year period starting 10 years after die‐off, shortly after which some genets began spreading horizontally by rhizomes. The aboveground biomass was estimated, and genets were discriminated in 9‐m2 plots placed under both canopy gaps and closed canopies. Overall, the results suggest that the survival and spread of more productive genets and the spatial expansion of genets into closed canopies underlie the proliferation of S. kurilensis. Compared to canopy gaps, the recovery rate of biomass was much slower under closed canopies for the first 10 years after the die‐off, but became accelerated during the next 7 years. Genet survival was greater for more productive genets (with greater initial number of culms), and the spaces occupied by genets that died were often colonized afterward by clonal growth of surviving genets. The number of genets decreased under canopy gaps due to greater mortality, but increased under closed canopies where greater number of genets colonized clonally from outside the plots than genets died. The colonizing genets were more productive (having larger culms) than those originally germinated within the plots, and the contribution of colonizing genets to the biomass was greater under closed canopies. Our study emphasizes the importance of investigating genet dynamics over relevant spatiotemporal scales to reveal processes underlying the success of clonal plants in heterogeneous habitats.

“…“Bamboo” is the common term for plants in the subfamily Bambusoideae, a diverse group with c. 121 genera and 1,662 species worldwide (Canavan et al, ). These grasses are distributed mainly in tropical and subtropical areas, but also occur in mild‐temperate regions in south and southeast Asia (Lobovikov, Ball, Guardia, & Russo, ).…”

The Asian‐Melanesian bambusicolous genus Myriodiscus is related to the genus Tympanis, the North American‐European tree pathogen

Species of Tympanis are well‐known pathogens in Holarctic forests, but we know little about their relationship to other genera in Tympanidaceae. The genus Myriodiscus, remarkable macroscopically and a possible pathogen on bamboo, has a complicated taxonomic history and has not been conclusively placed phylogenetically. Species of Myriodiscus have been described under two other generic names, Ascotremellopsis and Gelatinomyces, the latter being related to the pathogenic genus Collophorina. There has been no formal synonymy of these three bambusicolous genera or agreement on their systematic positions. We combine accurate micromorphology and DNA sequence data to show the link between Tympanis and Myriodiscus and reveal previously unrecognized features of the latter. These two genera show a type of ascus development unique in the Leotiomycetes. With this new data, we have resolved past confusions over the identity of these fungi, determined their systematic position and have proposed the proper synonymies for Myriodiscus sparassoides and one new combination (M. conus).
