The global naturalized Alien Flora (GloNAF) database

This dataset provides the Global Naturalized Alien Flora (GloNAF) database, ver-sion 1.2. Glo NAF represents a data compendium on th e occurrence and identit y of naturalizedalien vascular plant taxa across geographic regions (e.g. countries, states, provinces, districts,islands) around the globe. The dataset includes 13,939 taxa and covers 1,029 regions (including381 islands). The dataset is based on 210 data sources. For each ta x on-b y-region combination, wepr ovide information on whether the tax on is consider ed to be naturalized in the specific region(i.e. has established self-sustaining popula tions in the wild). Non-native taxa are marked as“alien”, when it is not clear whether they are naturalized. To facilitate alignment with other plantdatabases, we pro v ide f or each taxon the name as given in the original data source and the stan-dardized taxon and family names used by The Plant List Version 1.1 (http://www.theplantlist.org/). We pro vide an ESRI shapefile including polygons f or each region and informa tion on whetherit is an island or a mainland region, the country and the Taxonomic Databases Working Group(TDWG) regions it is part of (TDWG levels 1–4). We also provide several variables that can beused to filter the data according to quality and completeness of alien taxon lists, which varyamong the combinations of regions and da ta sources. A pre vious version of the GloNAF dataset(version 1.1) has already been used in several studies on, for example, historical spatial flows oftaxa between continents and geographical patterns and determinants of naturalization across dif-ferent taxonomic groups. We intend the updated and expanded GloNAF version presented hereto be a global resource useful for studying plant inv asions and changes in biodiversity from regio-nal to global scales. We release these data into the public domain under a Crea ti ve CommonsZer o license waiver (https://creati v ecommons.org/share-y our -work/public-domain/cc0/). Wheny ou use the da ta in your publication, we request that y ou cite this da ta paper. If GloN AF is amajor part of the data analyzed in your study, you should consider inviting the GloNAF coreteam (see Metadata S1: Originators in the Overall project description) as collaborators. If youplan to use the GloNAF dataset, we encourage y ou to contact the GloNAF core team to checkwhether there have been recent updates of the dataset, and whether similar analyses are already ongoing

Data from: The role of species pools in determining species diversity in spatially heterogeneous communities

1. The 'habitat-specific species pool hypothesis' proposes that differences between habitats in the sizes of their species pools are the main drivers of diversity responses to habitat heterogeneity. Empirical tests of this hypothesis are not trivial since species might be missing from ecologically suitable habitats due to limited dispersal, while others may occur in unsuitable habitats by means of source-sink dynamics and mass effect. 2. We tested the habitat-specific species pool hypothesis in a local, environmentally heterogeneous community of annual plants using a novel 'ecological selection' experiment. Mixtures of seeds representing the whole community were sown in each habitat, and the emerging species were exposed to six generations of selection by environmental filtering and competition while being blocked from dispersal. A comparison of the total number of species that were able to survive in each habitat (i.e., to pass the selection test) with data on species richness in the natural community allowed us to test the degree to which observed differences in species richness between habitats could be explained by differences in the sizes of the respective species pools. 3. Results supported the species pool hypothesis, showing that differences in the sizes of the habitat-specific species pools were important in determining diversity responses to habitat heterogeneity. Moreover, species richness showed a unimodal response to local-scale gradients in habitat productivity, and this response could be attributed to underlying differences in species-pool sizes. Both results were robust to properties of the data and the method of analysis. 4. Synthesis. Our results provide a strong experimental evidence that differences in the sizes of habitat-specific species pools might be important in shaping the diversity of local communities. Future theoretical and empirical studies in community ecology should explore the potential sources and implications of such differences

Isatis Armena (Brassicaceae), New For Flora Palaestina

We report three records of Isatis armena L. (Brassicaceae) from southwestern Jordan, new for Flora Palaestina. The species, typically of a broad Irano-Turanian distribution, is unprecedentedly reported from the Saharo-Arabian floristic region, nearly 1000 km remote from its known range

The Red Plants of Israël : a proposal of updated and revised list of plant species protected by the law

The list of plant species protected by the law in Israel, established in 1964, includes 268 wild plant species. This list contains mainly attractive flowering plants and includes many ambiguities. The list includes plant species that are highly abundant, genera without specifying the species and plants that are not natives in Israel. Thus, the existing list of plants species protected by the law is insufficient for the current conservation needs of Israel. Since the species were not selected on the basis of any quantitative data, it is highly disadvantaged for conservation. We suggest an update and revised list of plant species to be protected. Entry criterion of the revised list is rarity, defined as less than 100 grid cells of one square km (0.5% of Israel area) in which the plant is present. The criteria for inclusion in the red list are (i) rarity, (ii) attractivity of the plant for picking the flower or for commercial use, (Hi) endemism, (iv) life form of tree or a shrub, and (v) rate of extinction or habitat destruction, combined together because of the correlation exists. The revised list includes 543 species, 0.25 of the 2167 plant species in the Israeli flora. Of the list of the “red plants ”, 1 19 species are present in 1 to 3 sites and 307 species present in less than 30 sites. The proposed list might be a better tool in nature conservation in Israel, regarding parameters affecting extinction probabilities.La liste des végétaux supérieurs d’Israël protégés par la loi, établie en 1964, comporte 268 espèces sauvages. Cette liste contient principalement de nombreuses phanérogames attractives, mais beaucoup d’ambiguïtés existent. En effet, cette liste inclut des végétaux abondants et des genres au sein desquels les végétaux non indigènes ne sont pas spécifiés et exclus. De plus, les espèces mentionnées n’ont pas été sélectionnées sur la base de données quantitatives. Ainsi, la liste actuelle des plantes protégées s’avère insuffisante par rapport aux nécessités de conservation en Israël. Nous suggérons donc une liste révisée et mise à jour des plantes protégées par la loi. Le critère d’entrée dans la liste revisée repose sur la rareté, définie comme la présence d’une plante dans moins de 100 cellules de 1 km2 (0,5% de la surface d’Israël). Les critères d’inclusion dans la liste sont (i) la rareté, (ii) l’attractivité de la plante, vis-à-vis de la cueillette ou d’un usage commercial,, (iii) l’endémisme, (iv) le type biologique, (v) les taux d’extinction ou de destruction des habitats, souvent combinés ensemble. La liste révisée comporte 543 espèces, soit 25 % des 2167 végétaux supérieurs recensés en Israël. Dans cette liste rouge, 119 espèces ne se rencontrent que dans 1 à 3 sites, et 307 plantes sont présentes dans moins de 30 sites. Cette proposition de nouvelle liste rouge représente un outil actuellement plus adapté à la conservation de la nature en Israël, en regard des divers paramètres responsables des probabilités d’extinction des espèces végétales.Shmida Avi, Fragman Ori, Nathan Ran, Shamir Zvi, Sapir Yuval.
