Monitoring of persistent organic pollutants in the polar regions: knowledge gaps & gluts through evidence mapping

2017

Persistent organic pollutants (POPs) are widespread compounds that accumulating in polar regions canalise through trophic webs. Although several dozens of studies have been carried out in the last decades, the information is generally scattered across a large number of literature sources. This does not allow an efficient synthesis and constraints our understanding on how address future monitoring plans and environmental conservation strategies on the Polar Regions with respect to POPs. Thus, here, we present the outcome of a systematic map (SM) to scope, screen and chart evidences from literature dealing with POPs in Polar regions. The SMs strive to produce rigorous guidelines and have rece…

New insights on the occurrence and conservation status in Italy of Alessioporus ichnusanus (Boletaceae), an IUCN red listed mycorrhizal species

2020

The conservation status of Alessioporus ichnusanus is discussed considering new insights emerged from the IUCN global assessment. New locations were identified and Italy is confirmed as the center of distribution of this species. According to the IUCN categories and criteria, A. ichnusanus is assigned to the category Vulnerable C2a(i).

Analysis of population genetic structure and variability using RAPD markers in the endemic and endangered Limonium dufourii (Plumbaginaceae)

1998

Limonium dufourii (Plumbaginaceae) is a triploid species, with apomictic reproduction, endemic to the east mediterranean coast of Spain, where it is present in only six populations with a few individuals in most of them. L. dufourii is included in the Red List of Endangered Species by the IUCN. Genetic variation and population structure in this species has been studied using RAPDs. Twelve different primers provided 124 reliable bands of which 33 were polymorphic among the 165 individuals analysed. Those polymorphic bands were able to define 44 different patterns, of which all but six were present in only one population. Several methods for statistical evaluation have been used for intra- an…

Discovery of a second locality for the narrow endemic Anthemis ismelia (Asteraceae) in NW Sicily

2017

A new population of Anthemis ismelia (Asteraceae) has been discovered on Mt Pecoraro (Cinisi, NW Sicily), a limestone headland at about 14 km from Mt Gallo (Palermo), the locus classicus et unicus of this species described in 1884. Taxonomic framework, distribution update, habitat characterisation, ecology and phytosociological framework are provided, as well as meta-population numerical estimates and risk status assessment.

Ecological aspects of plants inhabiting Mediterranean cliffs. Challenges and prospects of life in vertical environments

2021

[ES] Esta tesis investiga las oportunidades, desafíos y limitaciones para la investigación en el campo de la ecología vegetal, en el contexto de los acantilados mediterráneos. En concreto, las especies casmofiticas, cuyos hábitats naturales se caracterizan por su acusada pendiente. Las laderas de las montañas de piedra caliza en la proximidad del mar, en la parte central y occidental del área mediterránea se consideran objetos de estudio. Los estudios se llevaron a cabo en los cinturones costeros de montaña de las costas del noroeste de Sicilia y la costa diánica en la Comunidad Valenciana. El primer capítulo, titulado "The complexity of environmental factors: cliff microclimate", investiga…

Bryophytes of Europe Traits (BET) dataset

2023

The Bryophytes of Europe Traits (BET) dataset includes values for 65 biological and ecological traits and 25 bioclimatic variables for all 1816 bryophytes included in the European Red List (Hodgetts et al. 2019). The traits are compiled from several regional trait datasets and manually complemented using Floras, species-specific literature and expert knowledge. The bioclimatic variables are calculated using the European range of each species. Details regarding the trait compilation and extraction of bioclimatic variables can be found in the corresponding data paper (Van Zuijlen et al. 2023).

A new polyploid species of Limonium (Plumbaginaceae) from the Western Mediterranean basin

2015

A new species of Plumbaginaceae, Limonium irtaensis, is described and illustrated from the Western Mediterranean basin (Iberian Peninsula). The new species is triploid (2n = 26) and shows a papillate stigma and pollen with a fine reticulate exine (B type). A detailed morphological description is given, and its main diagnostic characters are compared with the related species. Conservation status has been assessed according to the IUCN protocol.

First record of Lindenia tetraphylla (Vander Linden, 1825) and rediscovery of Orthetrum nitidinerve (Selys, 1841) in Sicily (Insecta: Odonata)

2017

The first Sicilian record of Lindenia tetraphylla and a new regional record of Orthetrum nitidinerve, species not recorded since 1975 in mainland Sicily, are here reported. All individuals of L. tetraphylla and O. nitidinerve were observed in the same site in the province of Trapani.
