“…Serratia marcescens ssp. marcescens (ATCC ® 13880™) was chosen as the invader because its ability to break DNA allowed easy recognition from other species using simple plating techniques (Ketola et al 2016 b, Ketola et al 2017). The 3 community species used in this study showed relatively high resistance against the invading S. marcescens , when reared together: Pseudomonas chlororaphis ATCC ® 17418™, Enterobacter aerogenes ATCC ® 13048™ and Leclercia adecarboxylata ATCC ® 23216™ (Ketola et al 2017).…”

“…We used a standard dilution series technique to achieve a 10 5 -fold dilution that allowed the counting of separate colonies on agar plates. We plated the samples on DNase test agar with methyl green (Becton and Dickinson and Company, Sparks, MD; premade at Tammer-tutkan maljat, Tampere, Finland) that enabled the separation of S. marcescens from the community species (see: Ketola et al 2016 b, Ketola et al 2017). The fate of specific community species was not monitored during the invasion experiment, due to frequent supplementation of species.…”

For 27 instance, fluctuations can directly increase the risk of invasions of alien species into 28 new areas, as these species have repeatedly been proposed to benefit from disturbances. 29At the same time increased environmental fluctuations may also select for better 30 invaders. However, selection by fluctuations may also influence the resistance of 31 communities to invasions, which has rarely been tested. We tested eco-evolutionary 32 dynamics of invasion with bacterial clones, evolved either in constant or fluctuating 33 temperatures, and conducted experimental invasions in both conditions.

Some species benefit 50 from these changes, and invasions and range expansions have been documented for 51 many taxa (Parmesan & Yohe, 2003; Hickling et al. 2006; Bebber et al. 2013). In 60One possible evolutionary explanation for the emergence of invasive species and 61 genotypes is that they have evolved in a disturbed and fluctuating environment. It has 62 been suggested that rapid fluctuations in particular, can select for traits that could 63 promote invasion success, such as high population growth rate, plasticity and 64 persistence (Levins, 1968; Turelli & Barton, 2004; Meyers et al. 2005; Lee & 65 Gelembiuk, 2008). Climate change has been suggested to lead to increased extreme 66 events (e.g. Stocker et al. 2013), but the pre-adaptive role of fluctuating environments 67on invasions has seldom been tested (Lee & Gelembiuk, 2008; Ketola et al. 2013).

“…In contrast to our hypothesis propagule pressure was less important than biotic interactions in driving variation in microbial composition and ecosystem functioning ( Figure 2). In both macro-and micro-organism studies increasing the number of invading individuals and the number of repeated introductions leads to higher invasion success in both field and laboratory experiments (10,15,20,21,39,48,49). Invasions with large numbers of diverse taxa compared to single taxa may increase the importance of biotic interactions relative to propagule pressure.…”

Microbial probiotics are designed to improve functions in diverse ecosystems, yet probiotics often fail to have the desired beneficial effects. The introduction of probiotics to an environment with a preexisting microbiome is analogous to an invasion event, but is rarely considered in this light. Here, we tested the relative importance of propagule pressure (inoculation dose and frequency) compared to biotic interactions (composition of introduced and resident communities) in driving microbial composition and functional outcomes following microbial community invasions in experimental microcosms. Ecosystem functioning was assessed through measurements of CO2 production and DOC (dissolved organic carbon) accumulation, an activity and an environmental modification metric, respectively. Further, to test the dependence of propagule pressures versus biotic interactions was dependent on environmental context, experiments were performed on two different substrates, R2A agar and plant litter. In both environments, we found that biotic interactions were more important than propagule pressure in driving microbial composition. Moreover, bacteria were more successful invaders than fungi. While successful invasion is a first step, ultimately the success of microbial invasions in microbiome engineering applications is measured by the impact on ecosystem functioning. As with shaping the microbiome composition, biotic interactions were key to functional outcomes, but the magnitude of the functional impact varied by environment. Identifying general principles that determine the community composition and functioning following microbial invasions is key to efficient community engineering.

Untangling the positive association of phylogenetic, functional, and taxonomic diversity with alien bird species richness

Understanding the ecological mechanisms behind biological invasions remains a major focus of conservation biology and ecosystem management. Several hypotheses highlight that different facets of native biodiversity affect the establishment and spread of alien species. Here, we approach this question by examining the spatiotemporal relationship between alien bird species richness and different facets of biodiversity (taxonomic, functional, and phylogenetic) using breeding bird atlases for three U.S. states and for two time periods in each state. We associated native species richness, and functional and phylogenetic diversity with alien species richness, using generalized least squares models. Our results show that, consistently, across the three states and two time periods examined, alien species richness is positively associated with native diversity, and particularly with phylogenetic diversity. The relative importance of biodiversity metrics reflecting the functional or phylogenetic range occupied by the assemblage seems to advocate in favor of the importance of resource diversity as a main driver of both native and alien diversity. The secondary importance of biodiversity facets reflecting species functional or phylogenetic similarity, along with the lack of importance of functional or phylogenetic clustering or overdispersion, implies that if this relationship is shaped by biotic interactions, then biotic interactions facilitating coexistence (including even processes like predator‐mediated coexistence) are far more important than adversarial interactions like competition, at least at the scale of our analysis. Finally, the dominance of phylogenetic metrics over functional ones highlights the adaptive potential of a community accumulated over long lineage history may play an additional role as a source of information on evolutionary processes driving diversity patterns.
