To have an updated checklist available for a given area is crucial for many purposes (educational, conservation, management, etc.). In this paper, a complete and updated checklist of the vascular flora of Sierra Nevada mountain range (SE Spain), a recognized hotspot for plant diversity in the Mediterranean basin, is presented. It includes 2,353 taxa, 359 more than in the previous checklist (an increase of 15.25%). Also, data are shown on composition (in terms of families, number of hybrids, native/alien species, endemics, etc.) and threat status according to the IUCN. The result is a complete and updated checklist flora of this recognised biodiversity Mediterranean hotspot.

AbstractClimate change impacts are of a particular concern in small mountain ranges, where cold-adapted plant species have their optimum zone in the upper bioclimatic belts. This is commonly the case in Mediterranean mountains, which often harbour high numbers of endemic species, enhancing the risk of biodiversity losses. This study deals with shifts in vascular plant diversity in the upper zones of the Sierra Nevada, Spain, in relation with climatic parameters during the past two decades. We used vegetation data from permanent plots of three surveys of two GLORIA study regions, spanning a period of 18 years (2001–2019); ERA5 temperature and precipitation data; and snow cover durations, derived from on-site soil temperature data. Relationships between diversity patterns and climate factors were analysed using GLMMs. Species richness showed a decline between 2001 and 2008, and increased thereafter. Species cover increased slightly but significantly, although not for endemic species. While endemics underwent cover losses proportional to non-endemics, more widespread shrub species increased. Precipitation tended to increase during the last decade, after a downward trend since 1960. Precipitation was positively related to species richness, colonisation events, and cover, and negatively to disappearance events. Longer snow cover duration and rising temperatures were also related to increasing species numbers, but not to cover changes. The rapid biotic responses of Mediterranean alpine plants indicate a tight synchronisation with climate fluctuations, especially with water availability. Thus, it rather confirms concerns about biodiversity losses, if projections of increasing temperature in combination with decreasing precipitation hold true.

<p>Mar Menor (SE, Spain) is one of the largest coastal lagoons in the Mediterranean basin. Its ecological and economic significance has led to its inclusion in several protection programmes, both on a national and international level. In the last decades, this semiconfined habitat has been under high anthropogenic pressure from agricultural, mining and tourism activities, which have resulted in significant changes, such as eutrophic events and their cascading ecological effects. Previous research suggests that this degradation is linked to the introduction of nutrients and contaminants to this ecosystem, which are accumulated in the sediments of the lagoon. In this work, sediment cores from key locations of the Mar Menor were collected in order to estimate the amount of accumulated chemical compounds, such as metals and organic compounds. The results of this study are used to reconstruct the historical record of contaminants, which can fuel future contamination episodes in the lagoon.  </p><p>  </p>

Invasive alien species (IAS) negatively impact the environment and undermine human well-being, often resulting in considerable economic costs. The Mediterranean basin is a culturally, socially and economically diverse region, harbouring many IAS that threaten economic and societal integrity in multiple ways. This paper is the first attempt to collectively quantify the reported economic costs of IAS in the Mediterranean basin, across a range of taxonomic, temporal and spatial descriptors. We identify correlates of costs from invasion damages and management expenditures among key socioeconomic variables, and determine network structures that link countries and invasive taxonomic groups. The total reported invasion costs in the Mediterranean basin amounted to $27.3 billion, or $3.6 billion when only realised costs were considered, and were found to have occurred over the last three decades. Our understanding of costs of invasions in the Mediterranean was largely limited to a few, primarily western European countries and to terrestrial ecosystems, despite the known presence of numerous high-impact aquatic invasive taxa. The vast majority of costs were attributed to damages or losses from invasions ($25.2 billion) and were mostly driven by France, Spain and to a lesser extent Italy and Libya, with significantly fewer costs attributed to management expenditure ($1.7 billion). Overall, invasion costs increased through time, with average annual costs between 1990 and 2017 estimated at $975.5 million. The lack of information from a large proportion of Mediterranean countries, reflected in the spatial and taxonomic connectivity analysis and the relationship of costs with socioeconomic variables, highlights the limits of the available data and the research effort needed to improve a collective understanding of the different facets of the costs of biological invasions. Our analysis of the reported costs associated with invasions in the Mediterranean sheds light on key knowledge gaps and provides a baseline for a Mediterranean-centric approach towards building policies and designing coordinated responses. In turn, these could help reach socially desirable outcomes and efficient use of resources invested in invasive species research and management.

Artificial lakes play an important role in maintaining the valuable biodiversity linked to water bodies and related habitats. The vascular plant diversity of eight reservoirs and surrounding areas in southern Italy was inventoried and further analysed in terms of biodiversity. A total of 730 specific and subspecific taxa were recorded, with 179 taxa in the poorest area and 303 in the richest one. The results indicate a good richness of the habitats surrounding the water basins, with some species of nature conservation interest and only a few alien species.

This work highlights the importance of the vascular flora of eastern Andalusia within the hotspot of the Mediterranean Basin, analysing 3726 taxa, which represent 42.0% of the Iberian Peninsula and 29.9% of European floras. Notably, 10.3% of the flora is endemic (350 taxa), constituting 34.3% of the endemism of the Iberian Peninsula and Balearic Islands, and 2.6% of those of the Mediterranean Basin, which include 6 of the 17 endemic genera of the Iberian Peninsula and Balearic Islands, 3 of these being exclusive of the territory analysed. Chamaephytes and hemicryptophytes make up 45.5% of the flora, with decreasing values for the therophytes as altitudes rise (41.1-8.1%) and increasing values for hemicryptophytes (22.4%-63.2%). Mediterranean taxa comprise 39.2%, followed by Ibero-North African taxa (15.3%), Iberian (13.9%), European (11.3%) and local endemism (9.4%). Of these taxa, 12.5% are threatened, according to the criteria of the UICN. Tanacetum funkii, exclusive of this area, is considered extinct. Only 6 families account for 43.5% of the threatened taxa. The Mesomediterranean thermotype (600-1400 m a.s.l.) harbours 82.8% of the species, with a maximum of between 700-800 m a.s.l. and with two zones of minimums: from -100 to 0 m a.s.l. and from 3300 to 3400 m a.s.l.

Andalusia, together with Morocco, is considered part of one of the two main biodiversity centres existing in the Mediterranean Basin; the other one is in the east and includes part of Turkey and Greece. The Andalusian flora has a fundamental role in this recognition, having been studied since the 1st century A.D. Despite Andalusia having been visited by a myriad of Iberian and foreign botanists, there is still no synthetic work on this subject. In this contribution, we present the first checklist of the Andalusian vascular flora, listing 4437 taxa distributed in 171 families, 1107 genera, 4091 species, and 346 subspecies, of which 3958 are native and 479 alien. Therophytes predominate (1516, 34.2%), followed by hemicryptophytes (1219, 27.5%) and chamaephytes (628, 14.1%). In addition, 462 (10.4%) are endemic or sub-endemic to the territory, and 595 (13.4%) are subject to some degree of threat (135 critically endangered, 137 endangered, and 323 vulnerable).
