description: Consider a non-increasing function $Ψ$ from the positive reals to the positive reals with decay $o(1/x)$ as $x$ tends to infinity. Jarnik proved in 1930 that there exist real numbers $ζ_{1},...,ζ_{k}$ together with $1$ linearly independent over $\mathbb{Q}$ with the property that all $qζ_{j}$ have distance to the nearest integer smaller than $Ψ(q)$ for infinitely many positive integers $q$, but not much smaller in a very strict sense. We give an effective generalization of this result to the case of successive powers of real $ζ$. The method also allows to generalize corresponding results for $ζ$ contained in special fractal sets such as the Cantor set.

description: Antarctic minke whales (Balaenoptera bonaerensis, AMW) are an abundant, ice-dependent species susceptible to rapid climatic changes occurring in parts of the Antarctic. Here, we used remote biopsy samples and estimates of length derived from unoccupied aircraft system (UAS) to characterize for the first time the sex ratio, maturity, and pregnancy rates of AMWs around the Western Antarctic Peninsula (WAP). DNA profiling of 82 biopsy samples (2013–2020) identified 29 individual males and 40 individual females. Blubber progesterone levels indicated 59% of all sampled females were pregnant, irrespective of maturity. When corrected for sexual maturity, the median pregnancy rate was 92.3%, indicating that most mature females become pregnant each year. We measured 68 individuals by UAS (mean = 8.04 m) and estimated that 66.5% of females were mature. This study provides the first data on the demography of AMWs along the WAP and represents the first use of non-lethal approaches to studying this species. Furthermore, these results provide baselines against which future changes in population status can be assessed in this rapidly changing marine ecosystem.

description: In this paper we explore the entanglement of two relativistic spin-$1/2$ particles with continuous momenta. The spin state is described by the Bell state and the momenta are given by Gaussian distributions of product form. Transformations of the spins are systematically investigated in different boost scenarios by calculating the orbits and concurrence of the spin degree of freedom. By visualizing the behavior of the spin state we get further insight into how and why the entanglement changes in different boost situations.

description: Let $S$ be a compact oriented surface with boundary together with finitely many marked points on the boundary, and let $S^\circ$ be the same surface equipped with the opposite orientation. We consider the double $S_\mathcal{D}$ obtained by gluing the surfaces $S$ and $S^\circ$ along corresponding boundary components. We define a notion of lamination on the double and construct coordinates on the space of all such laminations. We show that this space of laminations is a tropical version of the symplectic double introduced by Fock and Goncharov. There is a canonical pairing between our laminations and the positive real points of the symplectic double. We derive an explicit formula for this pairing using the $F$-polynomials of Fomin and Zelevinsky.

Impossibility of perfectly-secure one-round delegated quantum computing for classical client
Creators: name: Morimae, Tomoyuki

Publisher: name: arXiv
Year: 2014
Subjects: subject: Quantum Physics (quant-ph)

description: Blind quantum computing protocols enable a client, who can generate or measure single-qubit states, to delegate quantum computing to a remote quantum server protecting the client's privacy (i.e., input, output, and program). With current technologies, generations or measurements of single-qubit states are not too much burden for the client. In other words, secure delegated quantum computing is possible for "almost classical" clients. However, is it possible for a "completely classical" client? Here we consider a one-round perfectly-secure delegated quantum computing, and show that the protocol cannot satisfy both the correctness (i.e., the correct result is obtained when the server is honest) and the perfect blindness (i.e., the client's privacy is completely protected) simultaneously unless BQP is in NP. Since BQP is not believed to be in NP, the result suggests the impossibility of the one-round perfectly-secure delegated quantum computing.

On a regular modified C-metric

description: A particular form of the C-metric is investigated, giving it a non-standard interpretation and removing any singularity at $r = 0$. In the weak field limit of the accelerating black hole, the proper acceleration $A$ of a static observer is constant and the geometry becomes conformally-flat (anti de Sitter). The stress tensor is of $Λ$-type ($Λ= -3a^{2}/8πG$) and its energy density is negative. We propose that $Λ$ is responsible of inertial forces that appear in uniformly accelerated systems (far from the accelerating source $m$ and for $r << 1/a$ the dominant term in the expression of $a^{r}$ is $-a cosθ$). The components of the stress tensor and all invariants of the conformally-flat Schwarzschild spacetime are regulated by means of the exponential factor $exp(-k/r), k > 0$.

description: We derive a general large deviation principle for a canonical sequence of probability measures, having its origins in random matrix theory, on unbounded sets $K$ of ${\bf C}$ with weakly admissible external fields $Q$ and very general measures $ν$ on $K$. For this we use logarithmic potential theory in ${\bf R}^{n}$, $n\geq 2$, and a standard contraction principle in large deviation theory which we apply from the two-dimensional sphere in ${\bf R}^{3}$ to the complex plane ${\bf C}$.
k-symplectic structures and absolutely trianalytic subvarieties in hyperkahler manifolds

description: Let $(M,I,J,K)$ be a hyperkahler manifold, and $Z\subset (M,I)$ a complex subvariety in $(M,I)$. We say that $Z$ is trianalytic if it is complex analytic with respect to $J$ and $K$, and absolutely trianalytic if it is trianalytic with respect to any hyperkähler triple of complex structures $(M,I,J',K')$ containing $I$. For a generic complex structure $I$ on $M$, all complex subvarieties of $(M,I)$ are absolutely trianalytic. It is known that a normalization $Z'$ of a trianalytic subvariety is smooth; we prove that $b_2(Z')$ is no smaller than $b_2(M)$ when $M$ has maximal holonomy (that is, $M$ is IHS). To study absolutely trianalytic subvarieties further, we define a new geometric structure, called k-symplectic structure; this structure is a generalization of the hypersymplectic structure. A k-symplectic structure on a 2d-dimensional manifold $X$ is a k-dimensional space $R$ of closed 2-forms on $X$ which all have rank 2d or d. It is called non-degenerate if the set of all degenerate forms in $R$ is a smooth, non-degenerate quadric hypersurface in $R$. We consider absolutely trianalytic tori in a hyperkahler manifold $M$ of maximal holonomy. We prove that any such torus is equipped with a non-degenerate k-symplectic structure, where $k=b_2(M)$. We show that the tangent bundle $TX$ of a k-symplectic manifold is a Clifford module over a Clifford algebra $Cl(k-1)$. Then an absolutely trianalytic torus in a hyperkahler manifold $M$ with $b_2(M)\geq 2r+1$ is at least $2^{r-1}$-dimensional.

description: We study the problem of rank aggregation: given a set of ranked lists, we want to form a consensus ranking. Furthermore, we consider the case of extreme lists: i.e., only the rank of the best or worst elements are known. We impute missing ranks by the average value and generalise Spearman's ρto extreme ranks. Our main contribution is the derivation of a non-parametric estimator for rank aggregation based on multivariate extensions of Spearman's ρ, which measures correlation between a set of ranked lists. Multivariate Spearman's ρis defined using copulas, and we show that the geometric mean of normalised ranks maximises multivariate correlation. Motivated by this, we propose a weighted geometric mean approach for learning to rank which has a closed form least squares solution. When only the best or worst elements of a ranked list are known, we impute the missing ranks by the average value, allowing us to apply Spearman's ρ. Finally, we demonstrate good performance on the rank aggregation benchmarks MQ2007 and MQ2008.

description: This report provides an overview of the data modelling approaches adopted in iHELP project. The main goal is to capture the necessary data for personalized healthcare scenarios and ‘transform’ them into ready-to-use parameters into the Holistic Health Records (HHRs). Based on the outcomes of the CrowdHEALTH project1, HHRs are structured health records that include several types of information relevant to patients’ health status, such as medical and clinical data, laboratory measurements as well as data related to patients’ social life and physical activity.
 The basis for the mapping procedure is the utilization of the Fast Healthcare Interoperability Resources (FHIR) specification, which is a standard for electronically exchanging healthcare information and data, taking advantage of existing logical and theoretical models. FHIR is a new specification based on industry tactics, capitalizing the successes and challenges gained through defining and implementing standards such as the HL7 v1&v2 and CDA. The description and expansion of the HHR model will be based on an ontological level in order to accomplish a high degree of semantic interoperability. Moreover, taking into account that iHELP is focused on different factors associated with Pancreatic Cancer and relevant care pathways, appropriate standards will be used. For this reason, the mapping procedure is based on mCode standard, which focuses on concepts and fields from the oncological domain.
 The ultimate goal is to achieve sharing of specific aspects of HHR between different health platforms taking advantage of key characteristics of HHR that will allow this inter-exchange, such as their scalability and extensibility.
Brooks Type Results for Conflict-Free Colorings and {a, b}-factors in graphs

description: A vertex-coloring of a hypergraph is conflict-free, if each edge contains a vertex whose color is not repeated on any other vertex of that edge. Let $f(r, Δ)$ be the smallest integer $k$ such that each $r$-uniform hypergraph of maximum vertex degree $Δ$ has a conflict-free coloring with at most $k$ colors. As shown by Tardos and Pach, similarly to a classical Brooks' type theorem for hypergraphs, $f(r, Δ)\leq Δ+1$. Compared to Brooks' theorem, according to which there is only a couple of graphs/hypergraphs that attain the $Δ+1$ bound, we show that there are several infinite classes of uniform hypergraphs for which the upper bound is attained. We provide bounds on $f(r, Δ)$ in terms of~$Δ$ for large~$Δ$ and establish the connection between conflict-free colorings and so-called $\{t, r-t\}$-factors in $r$-regular graphs. Here, a $\{t, r-t\}$-factor is a factor in which each degree is either $t$ or $r-t$. Among others, we disprove a conjecture of Akbari and Kano~[Graphs and Combinatorics 30(4):821--826, 2014] stating that there is a $\{t,r-t\}$-factor in every $r$-regular graph for odd $r$ and any odd $t

Charred wood remaining after a wildfire as a reservoir of macro- and micronutrients in a Mediterranean pine forest

description: Large amounts of logs and coarse woody debris remain in the ecosystem after wildfires. However, the relevance of the nutrient reservoir contained in the remaining post-fire woody debris for the ecosystem nutrient reserves is rarely considered. In this paper, we determine the carbon and nutrient concentrations in the partially charred wood after a wildfire along an altitudinal gradient and assess the relative magnitude of the nutrient reservoir in the wood in relation to those existing in the first 10-cm soil layer. Soils were poorly developed and nutrients limiting for the vegetation requirements. Charred woody material still contained a relatively high concentration of nutrients compared to those reported for unburnt pine wood, and in general, this decreased with altitude. Partially charred wood represented a considerable pool of nutrients, due to both the relatively high concentrations and to the great amount of biomass still present after the fire. Potential contributions of the charred wood were particularly relevant for N and micronutrients Na, Mn, Fe, Zn and Cu, as wood contained 2–9 times more nutrients than the soil. Post-fire woody debris constitutes therefore a valuable natural element as a potential source of nutrients, which would be lost from ecosystems in cases where it is removed.
Classification of Rank 2 Cluster Varieties

description: We classify rank $2$ cluster varieties (those for which the span of the rows of the exchange matrix is $2$-dimensional) according to the deformation type of a generic fiber $U$ of their ${\mathcal X}$-spaces, as defined by Fock and Goncharov [Ann. Sci. Éc. Norm. Supér. (4) 42 (2009), 865-930]. Our approach is based on the work of Gross, Hacking, and Keel for cluster varieties and log Calabi-Yau surfaces. Call $U$ positive if $\dim[Γ(U,{\mathcal O}_U)] = \dim(U)$ (which equals 2 in these rank 2 cases). This is the condition for the Gross-Hacking-Keel construction [Publ. Math. Inst. Hautes Études Sci. 122 (2015), 65-168] to produce an additive basis of theta functions on $Γ(U,{\mathcal O}_U)$. We find that $U$ is positive and either finite-type or non-acyclic (in the usual cluster sense) if and only if the inverse monodromy of the tropicalization $U^{\rm trop}$ of $U$ is one of Kodaira's monodromies. In these cases we prove uniqueness results about the log Calabi-Yau surfaces whose tropicalization is $U^{\rm trop}$. We also describe the action of the cluster modular group on $U^{\rm trop}$ in the positive cases.

p-adic interpolation of automorphic periods for GL(2)
Creators: name: Van Order, Jeanine
Publisher: name: arXiv
Year: 2014
Subjects: subject: Number Theory (math.NT)
subject: FOS: Mathematics

description: We give a new and representation theoretic construction of $p$-adic interpolation series for central values of self-dual Rankin-Selberg $L$-functions for $\operatorname{GL}_2$ in dihedral towers of CM fields, using expressions of these central values as automorphic periods. The main novelty of this construction, apart from the level of generality in which it works, is that it is completely local. We give the construction here for a cuspidal automorphic representation of $\operatorname{GL}_2$ over a totally real field corresponding to a $\mathfrak{p}$-ordinary Hilbert modular forms of parallel weight two and trivial character, although a similar approach can be taken in any setting where the underlying $\operatorname{GL}_2$-representation can be chosen to take values in a discrete valuation ring. A certain choice of vectors allows us to establish a precise interpolation formula thanks to theorems of Martin-Whitehouse and File-Martin-Pitale. Such interpolation formulae had been conjectured by Bertolini-Darmon in antecedent works. Our construction also gives a conceptual framework for the nonvanishing theorems of Cornut-Vatsal in that it describes the underlying theta elements. To highlight this latter point, we describe how the construction extends in the parallel weight two setting to give a $p$-adic interpolation series for central derivative values when the root number is generically equal to $-1$, in which case the formula of Yuan-Zhang-Zhang can be used to give an interpolation formula in terms of heights of CM points on quaternionic Shimura curves.

We compare classical mirror descent (Nemirovski-Yudin, 1979) with dual averaging (Nesterov, 2005) and Grigoriadis-Khachiyan algorithm (1995). Grigoriadis-Khachiyan algorithm has just proved to be a randomized mirror descent (dual averaging) with randomization in KL-projection of (sub)gradient to a unit simplex. We found out that this randomization is an optimal way of solving sparse matrix games and some other problems arising in convex optimization and experts weighting.

We replace the last condition with the existence of a nonconstant element in $E$.

description: Climate and land-use changes, which include the application of various types of organic and inorganic fertilisers, have been reducing the species diversity of Mediterranean grasslands and threatening its conservation. Annual plants are one of the most diverse functional groups of species in these grasslands, despite suffering competitive pressure from perennial herbaceous and woody species, and they are essential for ecosystem functioning and stability. To quantify how fertilisation modulates the impact of plant-to-plant interactions and climate fluctuations on the dynamics of annuals in Mediterranean grasslands. We hypothesised that the application of sewage sludge would increase competition between functional groups, reducing the abundance of annuals in the long-term, but would buffer the negative impacts of drought on the year-to-year fluctuation of the diversity of annuals. In a semi-natural species-rich Mediterranean grassland in northern Spain, we analysed the changes in the taxonomical and functional composition and diversity of annuals over 14 years in response to variations in the abundance of perennial herbaceous and woody species, climate fluctuations and fertilisation with sewage sludge. We quantified separately the patterns of year-to-year fluctuations and long-term trends. The frequency and diversity of annuals decreased with higher abundance of perennial herbaceous species, drought in June and cold winters. The addition of sewage sludge decreased the abundance of annuals in the long-term, seemed to promote competition between annuals and other functional groups at an interannual scale, and mitigated the negative effects of drought and cold. Fertilisation influences differently the temporal response of annuals to climate fluctuations and plant-to-plant interactions.

description: There is a large uncertainty regarding the direction and magnitude of projected changes in the pattern and quantity of precipitation in future climate change scenarios. As changes in precipitation are likely to greatly impact plant diversity and biomass in desert ecosystems, we undertook a water addition/exclusion experiment to quantify the responses of plant diversity and biomass. To quantify the short-term impacts of changing the quantity of precipitation on plant species diversity and productivity in a desert steppe ecosystem. A simulated precipitation manipulation (addition and exclusion) experiment was made with four treatments: precipitation decreased by 50% (P-50%), precipitation increased by 50% (P+50%), precipitation increased by 100% (P+100%) and natural precipitation (Control). The richness of annual and biennial species was related to treatment; above-ground biomass increased in dry years in the P+100% treatment. Water addition had no statistically significant impacts on below-ground biomass. Increase in above-ground biomass with added precipitation in a drought year was mainly contributed by perennial grasses, suggesting that, from a management point of view, perennial grasses should be the focus of mitigation of projected future precipitation changes.

description: We define persistent homology groups over any set of spaces which have inclusions defined so that the corresponding directed graph between the spaces is acyclic, as well as along any subgraph of this directed graph. This method simultaneously generalizes standard persistent homology, zigzag persistence and multidimensional persistence to arbitrary directed acyclic graphs, and it also allows the study of more general families of topological spaces or point-cloud data. We give an algorithm to compute the persistent homology groups simultaneously for all subgraphs which contain a single source and a single sink in $O(n^4)$ arithmetic operations, where $n$ is the number of vertices in the graph. We then demonstrate as an application of these tools a method to overlay two distinct filtrations of the same underlying space, which allows us to detect the most significant barcodes using considerably fewer points than standard persistence.

description: New concepts of governance take account of ambivalence, uncertainty, and distributed power in societal change. They aim for reflexivity regarding the limits of prognostic knowledge and actual control of complex processes of change. Adaptive management and transition management are two examples that evolved from the analysis of social–ecological and sociotechnical systems, respectively. Both feature strategies of collective experimentation and learning. In this paper, we ask how these two designs of reflexive governance consider politics. Based on a framework of different dimensions and levels of politics, we show that they are mainly concerned with problem solving by a focal process, but conflict and asymmetric power relations, as well as the embedding of processes within broader political contexts, are neglected. We suggest two routes for integrating politics into the design of reflexive governance: (1) recognize the politics of learning for sustainable development and develop safeguards against domination and capture by powerful actors, and (2) systematically consider the embedding of governance designs in political contexts and their ongoing dynamics for political fit.

description: We investigate whether arbitrarily small perturbations in global AdS space are generically unstable and collapse into black holes on the time scale set by gravitational interactions. We argue that current evidence, combined with our analysis, strongly suggests that a set of nonzero measure in the space of initial conditions does not collapse on this time scale. We perform an analysis in position space to study this puzzle, and our formalism allows us to directly study the vanishing-amplitude limit. We show that gravitational self-interaction leads to tidal deformations which are equally likely to focus or defocus energy, and we sketch the phase diagram accordingly. We also clarify the connection between gravitational evolution in global AdS and holographic thermalization.

description: Seaweed associated bacteria can be exploited for sustainable production and conservation of seaweeds, although limited information exists in several coastal waters in West Africa. Here, the diversity and abundance of bacteria on five seaweeds, Sargassum vulgare, Padina durvillaei, Hydropuntia dentata, Hypnea musciformis and Ulva fasciata, and surrounding seawaters across five coastal sites in the Central and Western regions of Ghana were investigated. Biochemical tests and MALDIâ€“TOF identification system were used to determine the bacteria diversity and abundance on the seaweeds and seawater. A total of 530 bacterial isolates, belonging to 28 species (and mostly Proteobacteria and Firmicutes) were identified. A higher diversity of bacteria species was found associated with the seaweeds (83%) than in seawater (17%). Bacterial composition was similar among taxonomically-related seaweeds. The brown (S. vulgare) and red (H. musciformis) seaweeds recorded the most and least diverse bacterial assemblage, respectively. Seasonally, bacterial diversity and abundance were marginally higher in the wet season. The study provides important baseline information on the spatial, temporal and taxonomic distribution of bacteria associated with commercially valuable seaweed species in the coastal areas of Ghana. The results are also important for the sustainable exploitation and conservation of these important macroalgae in Ghana and elsewhere.
Fragments of Youth: Young Men and the State in Honiara, Solomon Islands
Creators: name: Evans, Daniel
Publisher: name: The Australian National University

description: The thesis examines the lives of a group of young men who live in and around Honiara, the growing capital of Solomon Islands in the southwest Pacific. Based on field work mainly conducted in 2016 in two urban communities, Burns Creek and White River, it employs interviews and participant observation in order to understand how a segment of the population engages with their state. It presents a typically underarticulated perspective: that of unemployed and under-schooled young male urbanites. In undertaking this examination, issues related to the nature of the contemporary Solomon Islands state, state-society relations and processes of state-formation as perceived and experienced by its young male citizens are engaged with. The thesis is also concerned with representations of young urban men in Solomon Islands, assessing how has this cohort been encountered and considered by those around them, in popular discourse, policy engagements and strands of academic literature. While 'male youth' are the primary object of the thesis, they should not be considered a unitary, undifferentiated category. The study reveals dynamic elements of young urban men's socio-economic positionings, worldviews and day-to-day lives, as well as insights into the physical spaces that they inhabit and engage with. Various lenses and thematic foci are employed in the thesis' engagement with its protagonists: international development thought and practice; the actions of, and perceptions towards, the state's police force; public group violence on Honiara's streets; and young Honiara residents' involvement in illicit livelihoods. These encounters are highly relevant for providing insights into the state-male youth relationship. Outside of routine service provision, they are sites where many young Honiara men are most likely to come into contact with elements of the state. The findings presented challenge deficit framings of male youth. The research argues that in the main the young men studied have a difficult association with the Solomon Islands' state and have been problematically labelled and represented. The state-male youth relationship is one that cannot be neatly categorised nor defined by reference to rigid binaries. While the state is considered legitimate it is simultaneously resisted and preyed upon.

description: La vie sur Terre a commencé dans l'eau et des milliards d’années après les algues occupent 90% des espèces de la flore aquatique. Cependant, l’augmentation accélérée de l’industrialisation et de la population mondiale marquent toujours plus négativement l’environnement et bouleverse le climat. Depuis quelques décennies, des initiatives apparaissent en réaction à ce problème pour tenter d'en minimiser les impacts. De l’usage des matériaux écologiques à la création de villes régénératrices, certains architectes essayent aussi de contribuer à la résilience de l’ensemble des écosystèmes mondiaux et de nombreuses technologies sont créées prenant la nature comme source d'inspiration. Parmi ces projets en architecture, certaines sont basée sur des technologies utilisant des plantes marines. En effet, même si nous en parlons aujourd'hui comme d'une possible source d’énergie grâce à des photobioréacteurs utilisant les microalgues, elles ont traversé l’histoire architecturale dans la construction vernaculaire de maisons depuis le néolithique et à travers le monde. Loin de la logique technologique moderne et de la simple pensée sur l’efficacité énergétique, ce mémoire a comme objectif d'aborder d’une façon critique et analytique l’emploi des plantes marines dans le contexte des habitations vernaculaire à partir d’une valorisation des anciennes méthodes éco-culturelles et éco-esthétiques qui peuvent nous inspirer aujourd’hui pour créer une nouvelle architecture résiliente.

description: Computer-assisted surgery (CAS) plays a prominent role in certain surgical disciplines. We investigated the current perceptions and use of this technology for orbital surgery. An online survey was emailed to members of the American Society of Ophthalmic Plastic and Reconstructive Surgery, Canadian Society of Oculoplastic Surgery, and British Oculoplastic Surgery Society. Respondents were asked to describe their practice type and seniority, their frequency of orbital surgery, experience, use, and accessibility of CAS, and their opinion on the technology. There were a total of 151 responses across the societies. 105 respondents (69.5%) had been in attending/consultant practice for over 10 years, with over half (54.7%) working in academic/teaching hospitals. The majority (66.7%) had superficial or no experience with CAS. In total, 84.8% of respondents rarely or never use CAS for orbital surgery (n = 128). Posterior orbital surgery (64.2%) and orbital decompression (49.0%) were the two most useful reasons to implement CAS. Longer operating time (58.3%) and cost (54.8%) were the two most selected weaknesses for CAS, whereas improved accuracy in attaining surgical end point(s) (80.8%) and patient safety (63.6%) were the principal advantages. Type of practice was significantly associated with CAS availability/accessibility (p < 0.05). Proportion of orbital surgery performed in practice was significantly associated with both CAS experience and use (p < 0.05). Our study confirms an expected variation in the perception and use of CAS for orbital surgery. Demonstrated patient benefit and integration of refined and cost-effective CAS systems into operating room environments may influence its future role.

description: By favouring long-distance dispersal, anemochory is often associated with open and patchy habitats, whereas zoochory enables short-distance dispersal and prevails in closed and extensive habitats. Brazilian savanna (Cerrado) on shallow rocky soils (RS) have open vegetation and are patchily distributed, whereas savanna on deep soils (DS) have dense vegetation and occur in large stands. Thus, we predicted that zoochory would be favoured in DS and anemochory would characterise RS. We tested the hypothesis that vegetation structure and distribution patchiness are related to the characteristic dispersal mechanisms associated with closed and open habitats. We compared the abundance of dispersal mechanisms between DS and RS with generalised linear mixed models and used an indicator species analysis to identify species associated with each vegetation type. There was no difference between DS and RS in the number of species associated with one or the other dispersal mechanism. We found fewer-than-expected zoochorous individuals and more-than-expected anemochorous individuals in RS, and more zoochorous indicator species in DS. Habitat patchiness and openness are related to the composition of dispersal mechanisms. Open vegetation on shallow rocky soils favours long-distance dispersal relative to zoochory. This implies reduced plant establishment and increased leaflessness, being harsher on animal dispersers. Protected areas are often concentrated in RS, whereas DS are rapidly converted into croplands due to their excellent aptitude for mechanised agriculture. Conserving DS and RS requires a balanced complementary approach, that ensures that all landscape elements are adequately represented in protected areas.

description: Measures are needed to protect water sources from substances that are mobile, persistent and toxic (PMT) or
very persistent and very mobile (vPvM). PMT/vPvM substances are used in a diverse range of applications,
including consumer products. The combined application of the essential-use and functional substitution
concepts has been proposed to phase out substances of concern and support the transition to safer and
more sustainable chemicals, a key goal of the European Commission's Chemicals Strategy for Sustainability.
Here, we first identified the market share of PMT/vPvM containing cosmetic products. We found that 6.4%
of cosmetic products available on the European market contain PMT or vPvM substances. PMT/vPvM
substances were most often found in hair care products. Based on their high occurrence, the substances
Allura red (CAS 25956-17-6), benzophenone-4 (CAS 4065-45-6) and climbazole (CAS 38083-17-9) were
selected as case-studies for assessment of their functionality, availability of safer alternatives and
essentiality. Following the functional substitution framework, we found that the technical function of Allura
red was not necessary for the performance of some cosmetic products, making the use non-essential. For
other applications of Allura red, as well as all applications of benzophenone-4 and climbazole, the technical
function of the chemical was considered necessary for the performance. Via the alternative's assessment
procedure, which used experimental and in silico data and three different multicriteria decision analysis
(MCDA) strategies, safer alternatives were identified for all case-study chemicals. All assessed uses of PMT/
vPvM substances were thus deemed non-essential and should consequently be phased out.
