Local environmental conditions shape generalist but not specialist components of microbial metacommunities in the Baltic Sea
No full textMarine microbes exhibit biogeographical patterns linked with fluxes of matter and
energy. Yet, knowledge of the mechanisms shaping bacterioplankton community
assembly across temporal scales remains poor. We examined bacterioplankton 16S
rRNA gene fragments obtained from Baltic Sea transects to determine phylogenetic
relatedness and assembly processes coupled with niche breadth. Communities
were phylogenetically more related over time than expected by chance, albeit with
considerable temporal variation. Hence, habitat filtering, i.e., local environmental
conditions, rather than competition structured bacterioplankton communities in summer
but not in spring or autumn. Species sorting (SS) was the dominant assembly
process, but temporal and taxonomical variation in mechanisms was observed. For May
communities, Cyanobacteria, Actinobacteria, Alpha- and Betaproteobacteria exhibited
SS while Bacteroidetes and Verrucomicrobia were assembled by SS and mass effect.
Concomitantly, Gammaproteobacteria were assembled by the neutral model and patch
dynamics. Temporal variation in habitat filtering and dispersal highlights the impact of
seasonally driven reorganization of microbial communities. Typically abundant Baltic
Sea populations such as the NS3a marine group (Bacteroidetes) and the SAR86
and SAR11 clade had the highest niche breadth. The verrucomicrobial Spartobacteria
population also exhibited high niche breadth. Surprisingly, variation in bacterioplankton
community composition was regulated by environmental factors for generalist taxa
but not specialists. Our results suggest that generalists such as NS3a, SAR86, and
SAR11 are reorganized to a greater extent by changes in the environment compared to
specialists and contribute more strongly to determining overall biogeographical patterns
of marine bacterial communities

Unscrambling cyanobacteria community dynamics related to environmental factors
No full textFuture climate scenarios in the Baltic Sea project an increase of cyanobacterial
bloom frequency and duration, attributed to eutrophication and climate change. Some
cyanobacteria can be toxic and their impact on ecosystem services is relevant for
a sustainable sea. Yet, there is limited understanding of the mechanisms regulating
cyanobacterial diversity and biogeography. Here we unravel successional patterns
and changes in cyanobacterial community structure using a 2-year monthly timeseries
during the productive season in a 100 km coastal-offshore transect using
microscopy and high-throughput sequencing of 16S rRNA gene fragments. A total of
565 cyanobacterial OTUs were found, of which 231 where filamentous/colonial and
334 picocyanobacterial. Spatial differences in community structure between coastal and
offshore waters were minor. An “epidemic population structure” (dominance of a single
cluster) was found for Aphanizomenon/Dolichospermum within the filamentous/colonial
cyanobacterial community. In summer, this cluster simultaneously occurred with
opportunistic clusters/OTUs, e.g., Nodularia spumigena and Pseudanabaena.
Picocyanobacteria, Synechococcus/Cyanobium, formed a consistent but highly diverse
group. Overall, the potential drivers structuring summer cyanobacterial communities
were temperature and salinity. However, the different responses to environmental
factors among and within genera suggest high niche specificity for individual OTUs.
The recruitment and occurrence of potentially toxic filamentous/colonial clusters
was likely related to disturbance such as mixing events and short-term shifts in
salinity, and not solely dependent on increasing temperature and nitrogen-limiting
conditions. Nutrients did not explain further the changes in cyanobacterial community
composition. Novel occurrence patterns were identified as a strong seasonal succession
revealing a tight coupling between the emergence of opportunistic picocyanobacteria
and the bloom of filamentous/colonial clusters. These findings highlight that
if environmental conditions can partially explain the presence of opportunistic
picocyanobacteria, microbial and trophic interactions with filamentous/colonial
cyanobacteria should also be considered as potential shaping factors for singlecelled
communities. Regional climate change scenarios in the Baltic Sea predict
environmental shifts leading to higher temperature and lower salinity; conditions identified here as favorable for opportunistic filamentous/colonial cyanobacteria. Altogether,the diversity and complexity of cyanobacterial communities reported here is far greater than previously known, emphasizing the importance of microbial interactions between filamentous and picocyanobacteria in the context of environmental disturbance

Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
