Climatologically, the Grazalema Mountain is one of the most interesting areas of the Iberian Peninsula. However, it has not been studied in detail. Thus, a detailed pluviometric analysis is presented by addressing the origin of its high rainfall records. The results obtained show that the high rainfall levels on average, annually recorded in Grazalema, (more numerous than the ones recorded on the stations located at the windward slopes) are caused by a leeward depression effect (with reinforcement of Venturi effect) produced by the Corredor del Boyar. In addition, it is evidenced that with the creation of new georeferenced extrapolated points with rainfall values, it is possible to obtain a more accurate rainfall cartographic than with other methods, due to the fact that these maps are better suited to the relief.
从气候角度来看，Grazalema山是伊比利亚半岛上最有趣的地区之一。然而，它还没有被详细研究过。因此，通过解决其高降雨记录的起源，提出了详细的降雨计量分析。得到的结果表明，Grazalema记录的年平均高降雨量(比位于上风坡的站点记录的降雨量更多)是由Corredor del Boyar产生的背风洼地效应(加强了文丘里效应)引起的。此外，有证据表明，通过创建具有降雨值的新地理参考外推点，可以获得比其他方法更准确的降雨地图，因为这些地图更适合地形。

The recent digital edition of the Atlas of Pyrenean vascular flora, allow us to analyze some patterns of geographical distribution and environmental features of the most rare plant species. The aim of our study is to contribute to the knowledge of rarity and to the planning and implementation of plant conservation at a Pyrenean scale. Among the 363 selected taxa after applying the criteria of low occupancy (10% of the whole Pyrenean flora), 352 are present in less of the 2% of the territory and 11 occupy less than 4% distributed over a scarce number of populations (less than 30). Using a net of 10 x 10 Km UTM’s squares, rare plants appear represented in the 65% of the territory; the regions with highest rare plant density overlap those with the highest total plant number. The areas with the richest rare plants are placed at the East and West extremes (beside the Cap de Creus and at between San Sebastian and Irun respectively), at the center of the French National Park of the Pyrenees and the surroundings of the Spanish Monte Perdido area. Rare flora significantly differs from the whole flora in terms of taxonomic representation, altitudinal amplitude and distribution, chorology, life-forms, edaphic preference and habitats, but not in the naturalness of the habitats where they occur.

Glacier area studies in the Pyrenees reported over 2000 ha in 1850, 806.5 ha in the 1980s and 310.33 ha in 2008. In this work we carried out an updated (2016) estimation of the current glacier area of the Pyrenees, based on remote sensing and contrasted with in-situ observations of the most representative glaciers. Our results yield a glacier area of 242.06 ha for 2016. This implies a reduction of 88.25 % since 1850, and a rapid wastage since 1980s, confirming the accelerated shrinkage during the end of the 20 th century and the first decade of the 21 st century.

The recent “on line” edition of the Atlas of vascular flora of the Pyrenees, allow us now to delimit the floristic diversity and to analyze the spatial distribution and some environmental features to contribute to their ecological study and conservation. The native vascular flora of the Pyrenees consists in 3,652 species and subspecies of vascular plants. This figure places the Pyrenees as the second most important point of Europe plant diversity, after the Alps. Considering 6 geographical sectors, the central-south (76%) and both the easterns (75%) shelter the highest plant abundance. In the altitudinal gradient, the montane belt holds the highest plant richness (87% of the total). With respect to chorology, 32% of plants are eurosiberians and 29% mediterraneans, whereas alpine orophytes and boreoalpines account for 12.6% and 5% are endemisms. Concerning life-forms, hemicryptophytes (44%) and therophytes (20.4%) predominate, although the later decrease with altitude, while chamaephytes increase. Looking at the edafic affinity, 35% of plants are calcicolus and 21% silicicolus. Distribution according to habitats shows that near 30% of the flora occur in grasslands, 16% in wetlands, and a similar percentage (around 12-13%) in rocks, forest, shrublands and anthropic plant communities. Finally, taking into account the habitat naturalness, 47% of plants occur in high or very high preserved habitats, although almost a quarter of plants live in the most disturbed ones.

On the basis of the digital edition of the “Atlas of the vascular flora of the Pyrenees” (www.florapyrenaea. org), the alpine flora of this mountain range is delimited in order to know its diversity and the different patterns of its spatial distribution, along with some other environmental characteristics. The Pyrenean alpine flora is made up of 645 taxa (630 species and 15 subspecies). All the administrative regions harbour more than 60% of the alpine plants, with Catalonia and Aragon reaching the highest values (around 90%). Along the altitudinal gradient, the highest plant diversity is found between 2300 and 2600 m. a. s. l., although 25% of the total alpine flora goes beyond 3000 m. On the other hand, a remarkable number of alpine plants live in the lowlands, and thus more than 300 alpine plants can be found below 1500 m. The average altitude range of the alpine plants is 1369 m, 300 m wider than that observed for the whole Pyrenean flora. Life-forms, habitat distribution and habitat naturalness of alpine plants are significantly different from those of the whole Pyrenean flora. Distribution of abundance categories also shows values of rarity significantly lower among alpine plants than for the whole flora. More than half the Pyrenean endemic plants are present in the alpine flora. High diversity and wide ecological amplitude of the alpine flora must be taken into account either when considering vulnerability of alpine plants facing “global change” or when addressing conservation policies for the whole Pyrenees from a common perspective.

This book introduces the key stages of niche- based habitat suitability model building, evaluation and prediction required for understanding and predicting future patterns of species and biodiversity. Beginning with the main theory behind ecological niches and species distributions, the book proceeds through all major steps of model building, from conceptualization and model training to model evaluation and spatio- temporal predictions. Extensive examples using R support graduate students and researchers in quantifying ecological niches and predicting species distributions with their own data, and help to address key environmental and conservation problems. Reflecting this highly active field of research, the book incorporates the latest developments from informatics and statistics, as well as using data from remote sources such as satellite imagery. A website at www.unil.ch/ hsdm contains the codes and supporting material required to run the examples and teach courses. All three authors are recognized specialists of and have contributed substantially to the development of spatial prediction methods for species’ habitat suitability and distribution modeling. They published a large number of papers, overall cumulating tens of thousands of citations, and are ISI Highly Cited Researchers.

Is presented the recent discovery and characterization of a endorheic basin at the summit of the Sierra Palmitera, an abrupt foothill of the peridotite massif of Sierra Bermeja (SW of Spain) that reaches 1,473 meters above sea level. Given the nature of this littoral ultramafic mountain, this basin is considered a geomorphological exceptionality for the whole of the known peridotite outcrops. Fieldwork and interpretation of photographs, main methodological procedures of the research, and the use of GIS have allowed a first geographical reconnaissance and the mapping of the main physical features to detail scale (1: 5.000). The obtained results are: (1) a topographic map (equidistance of 5 meters) as basis of the thematic mapping; (2) the identification, characterization and mapping of the major geomorphological and edaphic units to the mentioned scale; (3) the characterization of the vegetation and flora of the basin through the phytosociological analysis, and the development of a vegetation map to scale detail. These results provide knowledge about the origin of the basin, its operation and its ecological role. As outstanding feature, the accumulation of sediment at the bottom of the basin allows the paleo-ecological study of vegetation from the charcoals deposited on the soil, highlighting the finding of charcoal of Abies pinsapo , species of spruce threatened currently absent in the location.

The Leaf area index (LAI) and the Fractional Photosynthetically Active Radiation (fPAR) are variables related to the structure of the plant canopy that can provide new keys for the understanding of post-fire vegetation processes. In this context, the objective of this work is to characterize different burned areas in Aragon using the MDC15A2 (LAI/fPAR) product from MODIS. There are two different types of analysis: (1) static analysis of LAI/ fPAR values from the compound of 2010; (2) multi-year follow-up in 6 large fires occurred in the 2000s, representa difetive of different environmental conditions. The methodological process is based on the selection of 18 forest fires (> 500 ha, occurred between 1975-2010) with digital cartography available; and the download of the product MCD13A2 MODIS (seasonal compounds of 8 days, first week of May and September). A temporal pattern of recovery in the values of LAI has been identified. Fires occurred more than 35 years ago have average LAI values > 1 (1.13/1.40, in September and May respectively), and low values of fPAR (~ 0.5). Meanwhile, a year after the fire LAI/fPAR average values do not exceed 0.20/0.40, respectively. On the other hand, a few months after the fire average LAI values < 0.25 have been observed. In general terms, the MODIS MDC15A2 (LAI/ fPAR) product features an enormous potential in the cartographic analysis of the biological processes of burned areas, despite the problems of interpretation derived from the spatial resolution of the product.

Ancient trees abundance has been compared with distribution of threatened forest vertebrate species at the province of Salamanca (Spain). A significant correlation between both parameters has been observed for the following considered species: imperial eagle ( Aquila adalberti ), black vulture ( Aegypus monachus ), iberian lynx ( Lynx pardinus ), red kite ( Milvus milvus ) and a group of forest bats ( Miniopterus schreibersii, Myotis bechsteinii, Myotis emarginatus, Myotis mystacinus, Myotis myotis, Nyctalus lasiopterus, Nyctalus noctula, Rhinolophus euryale, Rhinolophus ferrumequinum y Rhinolophus mehelyi ). It has been proved that there is an increase of threatened forest vertebrates biodiversity along with increasing ancient trees density at the municipalities of the province. Therefore, we can deduce that ancient trees density is a good indicator parameter of the conservation status of the forest ecosystem and it is essential for the maintenance of these endangered species.

Therefore, we can deduce that ancient trees density is a good indicator parameter of the conservation status of the forest ecosystem and it is essential for the maintenance of these endangered species.","PeriodicalId":39887,"journal":{"name":"Pirineos","volume":"28 1","pages":"020"},"PeriodicalIF":0.0,"publicationDate":"2016-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76130921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present paper is based on research work that has been carried out for more than 20 years with the purpose of consolidating a method of biogeographic valuation of different plant scenes at a global scale. A few years ago, as a result of a research stay, different units of the Mediterranean environment of Chile were assessed. Among the results, the sclerophyllous Mediterranean forest with palms ( Jubaea chilensis ) clearly called one’s attention because it not only achieved the highest scores in this setting, but it got the absolute record to date. The paper is centered on, presents and analyzes the results obtained in that unit, but this time with systematic inventories and assessments made in 2015. The base study area is concentrated in a small microbasin, El Quiteno, in the coastal mountains of Vina del Mar. The natural and cultural values do not differ from some formations of the surrounding, even from formations situated in the European setting, yet the conservation priority shoots up taking into account that the participations referred to the global threat factor are very high.
本文基于20多年来的研究工作，旨在巩固全球范围内不同植物景观的生物地理评价方法。几年前，作为一项研究停留的结果，对智利地中海环境的不同单位进行了评估。在这些结果中，地中海硬叶棕榈林(Jubaea chilensis)显然引起了人们的注意，因为它不仅在该设置中获得了最高的分数，而且还获得了迄今为止的绝对记录。本文以该单元所取得的成果为中心，进行了介绍和分析，但这次是在2015年进行了系统的盘点和评估。基地研究区集中在一个小的微盆地，El Quiteno，在Vina del mar的沿海山区。自然和文化价值与周围的一些地层没有什么不同，甚至与位于欧洲环境中的地层没有什么不同，但考虑到涉及全球威胁因素的参与者非常高，保护优先级迅速上升。
