title: Data from: Why concatenation fails near the anomaly zone

description: Genome-scale sequencing has been of great benefit in recovering species
 trees, but has not provided final answers. Despite the rapid accumulation
 of molecular sequences, resolving short and deep branches of the tree of
 life has remained a challenge, and has prompted the development of new
 strategies that can make the best use of available data. One such strategy
 – the concatenation of gene alignments – can be successful when coupled
 with many tree estimation methods, but has also been shown to fail when
 there are high levels of incomplete lineage sorting. Here, we focus on the
 failure of likelihood-based methods in retrieving a rooted, asymmetric
 four-taxon species tree from concatenated data when the species tree is in
 or near the anomaly zone – a region of parameter space where the most
 common gene tree does not match the species tree because of incomplete
 lineage sorting. First, we use coalescent theory to prove that most
 informative sites will support the species tree in the anomaly zone, and
 that as a consequence maximum-parsimony succeeds in recovering the species
 tree from concatenated data. We further show that maximum-likelihood tree
 estimation from concatenated data fails both inside and outside the
 anomaly zone, and that this failure cannot be easily predicted from the
 topology of the most common gene tree. We show that likelihood-based
 methods often fail in a region partially overlapping the anomaly zone,
 likely because of the lower relative cost of substitutions on discordant
 gene tree branches that are absent from the species tree. Our results
 confirm and extend previous reports on the performance of these methods
 applied to concatenated data from a rooted, asymmetric four-taxon species
 tree, and highlight avenues for future work improving the performance of
 methods aimed at recovering species tree.

title: Indicators of the co-created destination image of island destinations on social media – a comparison of DMOs, UGC and influencers (2025)

description: This dataset provides an overview of quantitative and qualitative indicators in the context of the co-created destination image of the archipelagos of Hawaii, the Canary Islands and the Seychelles. A total of 180 image posts on the social media platform Instagram were analysed during the second half of 2025, comparing posts from destination management organisations (DMOs), user-generated content (UCG) and posts from influencers. 

The indicators provide insights into the destination image elements depicted in the image posts, as well as contributing elements and associated emotions in a comparison of different island destinations and stakeholders. On this basis, comparative research can be conducted in the context of the digital destination image and the influence of various actors on it. This dataset can thus contribute to comparative vertical and horizontal analysis and thus to studies in the field of destination management, destination image, social media and technology.

title: Data from: Linking Avicennia germinans (Acanthaceae) architecture to gall richness and abundance in Brazilian Amazon mangroves

description: The diversity and abundance of gall-inducing organisms are directly
 proportional to the structural complexity of the host plant. This
 hypothesis is controversial for forest environments, such as mangroves.
 Avicennia germinans (L.), a principal mangrove tree species found in the
 Neotropical region, is considered to be a superhost for gall-inducing
 insects. Using a Generalized Linear Mixed Model (GLMM) based on the
 analysis of 1000 apical branches from 50 A. germinans trees, we examined
 the diversity and abundance of gall morphotypes (GM), together with the
 structural attributes of replanted 5- to 9-year-old mangroves, in the
 Amazon coast of Brazil. A total of 7602 galls were registered, averaging
 1.3±0.4 galls per leaf. Sixteen of the 22 morphotypes identified were
 found at all study sites. Two gall morphotypes (GM7 and GM4) were the most
 abundant, representing approximately 40 percent of the total. The
 structural complexity of the plant (mainly based on the number of leaves)
 directly affected the abundance and diversity of these organisms. While A.
 germinans is a superhost, this type of parasitism did not affect plant
 development or survival. The ample distribution of A. germinans, the
 formation of monospecific forests, and the high palatability of this plant
 make it an essential resource for the survival of the gall-inducing guild
 in the mangroves of the Neotropics.

title: Data from: Genotype by environment interaction for growth and Dothistroma resistance and clonal connectivity between environments in radiata pine in New Zealand and Australia

description: Twenty-eight clonal trials of radiata pine planted across Australia and
 New Zealand were used to investigate genetic variation and genotype by
 environment (G×E) interaction for diameter-at-breast-height (DBH), height
 and Dothistroma resistance (DO_R). The average narrow-sense heritabilities
 were 0.11, 0.21 and 0.30 while the average broad-sense heritabilities were
 0.27, 0.34 and 0.40 for DBH, height and Dothistroma resistance,
 respectively. Dothistroma resistance was assessed as the percentage of
 needles that were not affected by Dothistroma needle blight. G×E
 interactions were analysed using an approximate reduced factor analytic
 model. Apparent G×E interactions were estimated for DBH, height and
 Dothistroma resistance. Estimates of G×E interactions and their standard
 errors were strongly influenced by the level of connectivity between
 trials, in terms of common clones and common parents. When there was
 sufficient connectivity between trials (more than 30% common clones
 between trials), a high level of G×E interaction was found for DBH and
 height but not for Dothistroma resistance. In two simulated clonal trials
 planted in two environments, low connectivity between environments
 resulted in a lower estimated genetic correlation between environments
 with an increased standard error. These results suggest that the number of
 clones in common between clonal trials is a key factor for inclusion in
 future experimental designs for estimating G×E interaction. When designing
 clonal trials for use in multiple environments for accurately estimating
 the level of G×E, if the resource for creating connectivity between
 environments is limited, at least 30% of the clones need to be in common
 between environments.

title: Data from: Monophyletic origin and evolution of the largest crucifer genomes

description: Clade E, or the Hesperis-clade is one of the major Brassicaceae
 (Crucifereae) clades comprising some 48 genera and 351 species classified
 into seven tribes and is predominantly distributed across arid and montane
 regions of Asia. Several taxa have socio-economic significance, being
 important ornamental but also weedy and invasive species. From the
 comparative genomic perspective, the clade is noteworthy as it harbors
 species with the largest crucifer genomes but low numbers of chromosomes
 (n = 5 - 7). By applying comparative cytogenetic analysis and
 whole-chloroplast phylogenetics, we constructed the first partial and
 complete cytogenetic maps for selected representatives of Clade E tribes
 and investigated their relationships in a family-wide context. The
 Hesperis-clade is a well-supported monophyletic lineage comprising seven
 tribes: Anchonieae, Buniadeae, Chorisporeae, Dontostemoneae, Euclidieae,
 Hesperideae, and Shehbazieae. The clade diverged from other Brassicaceae
 crown-group clades during the Oligocene, followed by subsequent Miocene
 tribal diversifications in central/south-western Asia. The inferred
 Ancestral Karyotype of Clade E (CEK, n = 7) originated from an older n = 8
 genome, which was also the purported progenitor of tribe Arabideae (KAA
 genome). In most taxa of Clade E, the seven linkage groups of CEK either
 remained conserved (Chorisporeae) or were reshuffled by chromosomal
 translocations (Euclidieae). In c. 50% of Anchonieae and Hesperideae
 species, the CEK genome has undergone descending dysploidy toward n = 6
 (5). This genomic data elucidates early genome evolution in Brassicaceae,
 and paves the way for future whole-genome sequencing and assembly efforts
 in this, as yet genomically neglected group of crucifer plants.

title: Data from: Ecological correlates of extinction risk in Chinese birds

description: China is one of the countries with the richest bird biodiversity in the
 world. Among the 1372 Chinese birds, 146 species are considered threatened
 and three species are regionally extinct according to the officially
 released China Biodiversity Red List in 2015. Here, we conducted the first
 extensive analysis to systematically investigate the patterns and
 processes of extinction and threat in Chinese birds. We addressed the
 following four questions. First, is extinction risk randomly distributed
 among avian families in Chinese birds? Second, which families contain more
 threatened species than would be expected by chance? Third, which species
 traits are important in determining the extinction risk in Chinese birds
 using a multivariate phylogenetic comparative approach? Finally, is the
 form of the relationship between traits additive or nonadditive
 (synergistic)? We found that the extinction risk of Chinese birds was not
 randomly distributed among taxonomic families. The families that contained
 significantly more threatened species than expected were the hornbills,
 cranes, pittas, pheasants and hawks and eagles. We obtained eleven species
 traits that are commonly hypothesized to influence extinction risk from
 the literature: body size, clutch size, trophic level, mobility, habitat
 specificity, geographical range size, nest type, nest site, flocking
 tendency, migrant status and hunting vulnerability. After phylogenetic
 correction, model selection based on Akaike’s information criterion
 identified the synergistic interaction between body size and hunting
 vulnerability as the single best correlate of extinction risk in Chinese
 birds. Our results suggest that, in order to be effective, priority
 management efforts should be given both to certain extinction-prone
 families, particularly the hornbills, pelicans, cranes, pittas, pheasants
 and hawks and eagles, and to bird species with large body size and high
 hunting vulnerability.

title: Data from: Evolutionary processes, dispersal limitation and climatic history shape current diversity patterns of European dragonflies

description: We investigated the effects of contemporary and historical factors on the
 spatial variation of European dragonfly diversity. Specifically, we tested
 to what extent patterns of endemism and phylogenetic diversity of European
 dragonfly assemblages are structured by (i) phylogenetic conservatism of
 thermal adaptations and (ii) differences in the ability of post-glacial
 recolonization by species adapted to running waters (lotic) and still
 waters (lentic). We investigated patterns of dragonfly diversity using
 digital distribution maps and a phylogeny of 122 European dragonfly
 species, which we constructed by combining taxonomic and molecular data.
 We calculated total taxonomic distinctiveness and mean pairwise distances
 across 4,192 50 km × 50 km equal-area grid cells as measures of
 phylogenetic diversity. We compared species richness with corrected
 weighted endemism and standardized effect sizes of mean pairwise distances
 or residuals of total taxonomic distinctiveness to identify areas with
 higher or lower phylogenetic diversity than expected by chance.
 Broken-line regression was used to detect breakpoints in
 diversity–latitude relationships. Dragonfly species richness peaked in
 central Europe, whereas endemism and phylogenetic diversity decreased from
 warm areas in the south-west to cold areas in the north-east and with an
 increasing proportion of lentic species. Except for species richness, all
 measures of diversity were consistently higher in formerly unglaciated
 areas south of the 0°C isotherm during the Last Glacial Maximum than in
 formerly glaciated areas. These results indicate that the distributions of
 dragonfly species in Europe were shaped by both phylogenetic conservatism
 of thermal adaptations and differences between lentic and lotic species in
 the ability of post-glacial recolonization/dispersal in concert with the
 climatic history of the continent. The complex diversity patterns of
 European dragonflies provide an example of how integrating climatic and
 evolutionary history with contemporary ecological data can improve our
 understanding of the processes driving the geographical variation of
 biological diversity.

We also provide the breakpoints from segmented regressions of the relationship between latitude and four different measures of the diversity of European dragonfly assemblages (species richness, corrected weighted endemism, the residuals of total taxonomic distinctiveness against species richness and standardized effect sizes of mean pairwise distances).

title: Data from: How to quantify a distance-dependent landscape effect on a biological response

description: To quantify the effect of the surrounding landscape context on a
 biological response at a site, most studies measure landscape variables
 within discs centred on this biological response (threshold-based method).
 This implicitly assumes that the effect of a unit area of the landscape is
 consistent up to a threshold distance beyond which it drops to zero.
 However, it seems more likely that the landscape effect declines with
 increasing distance from the biological response point. Here we develop a
 method to quantify landscape context effects by weighting the landscape
 variables by functions that decrease with distance. We illustrate the
 method using abundance data on birds and insects, and compare the results
 to the threshold approach. We defined distance weighting functions by the
 function family (e.g. negative exponential, Gaussian…) and by the
 parameters for this function. We developed a method to simultaneously
 estimate the parameters characterizing the effect of the landscape
 variables and the parameters of the best weighting functions. For each
 test dataset, we determined which weighting function (family and
 parameters) had the most support, by optimizing the model AIC. The
 distance-weighted method improved model support over the threshold-based
 method in three of four datasets, with the exponential power function
 selected as the best weighing function in all three cases. The observed
 differences between estimations of landscape context effects by the
 distance-weighted and the threshold methods have significant implications
 for landscape management. For example, the distance-weighted method
 suggests that managing a landscape for 90% of its effect on a focal
 population requires an area over five times larger than the area estimated
 by the threshold method, a situation that might apply for priority
 conservation of few remnant populations of a severely endangered species.
 In contrast, management for 30% of the landscape effect requires only
 about half the area estimated using the threshold method, a situation that
 might apply to a management situation with limited resources or low
 political/societal support. The distance-weighted method is applicable to
 any species-habitat relationship. More comparisons are needed to determine
 the situations in which distance-weighted estimation of landscape context
 effects is warranted over the simpler threshold method.

title: Data from: Peperomia (Piperaceae) from Trindade Island: a new species based on morphological and molecular data

description: Peperomia is one of the largest genera of basal angiosperms, with about
 1,600 species, distributed pantropically. The Brazilian oceanic island of
 Trindade is located about 1,200km off the Brazilian coast; its maximum
 altitude is 620ma.s.l. and its area is 9.28km2. Among the 113 species of
 vascular plants reported for Trindade Island there are two species of
 Peperomia: Peperomia beckeri, an endemic species known only from the type
 specimen; and Peperomia glabella.We re-evaluated specimens attributed to
 P. glabella from Trindade Island and compared them to specimens from the
 continent. The comparison included morphological analyses of the
 vegetative and reproductive organs, and a molecular phylogenetic study
 using the molecular markers trnK/matK and ITS. The trnK/matK marker showed
 significant differences between Peperomia from the mainland and Trindade.
 Together, these studies showed that the Peperomia occurring on Trindade is
 a species that differs both from those previously recorded on Trindade
 Island and from those on the continent, leading us to describe a new
 species. Peperomia segregata is endemic to Trindade, and would likely be
 considered critically endangered according to the IUCN criteria.
