Abstract Aim The first comprehensive checklist of European phytosociological alliances, orders and classes (EuroVegChecklist) was published by Mucina et al. (2016, Applied Vegetation Science , 19 (Suppl. 1), 3–264). However, this did not contain detailed information on the distribution individual vegetation types. Here we provide maps all alliances in Europe. Location Europe, Greenland, Canary Islands, Madeira, Azores, Cyprus Caucasus countries. Methods We collected data occurrence countries...
Abstract Aim Vegetation types of Mediterranean thermophilous pine forests dominated by Pinus brutia , halepensis pinaster and pinea were studied in various areas. However, a comprehensive formal vegetation classification these based on detailed data analysis has never been developed. Our aim is to provide the first broad‐scale large set plots. Location Southern Europe, North Africa, Levant, Anatolia, Crimea Caucasus. Methods We prepared European forest selected 7,277 plots cold‐sensitive...
Abstract The first comprehensive phytosociological classification of all vegetation types in Europe (EuroVegChecklist; Applied Vegetation Science , 2016, 19 3–264) contained brief descriptions each type. However, these were not standardized and mentioned only the most distinct features practical application system could be enhanced if users had option to select sets based on various combinations structural, ecological, biogeographical attributes. Based a literature review expert knowledge,...
We present a bioclimatological diagnosis of mainland Portugal, namely the thermotype and ombrotype maps following Rivas-Martínez's worldwide bioclimatic classification system. In order to obtain this diagnosis, we produced indices using, as base data, geostatistical interpolations air temperature precipitation. performed uncertainty propagation obtaining measures for maps: mean absolute errors root squared errors. For non-linear indices, besides usual approximation using Taylor expansion,...
Abstract Agricultural abandonment is a major driver of change in rural landscapes. Assumed to provide beneficial results the environment and conservation biota, triggers landscape biotic homogenization loss valuable species habitats. This article focuses on ecological effects challenges shifts extensive grazing regimes marginal pastureland Mediterranean mountains. We conceptualize navigated socioecological transition toward conservation‐oriented management after collapse historical land...
I present the Total Differential Value (TDV), an index designed for vegetation analysis based on operational concept of differential species, as classically illustrated by Heinz Ellenberg and Dieter Mueller-Dombois. Given a phytosociological table grouping its relevés, TDV is obtained averaging (DiffVal) each species in table. DiffVal, grounded combinatorial-discrete mathematics, quantifies power species. The novelty this approach lies distinction between two types absences: (i) absences...
An attempt to obtain a consistent spatial model of natural potential vegetation (NPV) for the mainland Portuguese territory is reported.Spatial modeling procedures performed in Geographic Information System (GIS) environment, aimed operationalize phytosociological expert-knowledge about putative distribution zona1 forest communities dominam continental territories.The paradigm NPV assumed was that RIVAS-MARTINEZ (1976) and et al. (1999), which presupposes, given territory, univocal...
Persistence of native forests is a global concern. We aimed at unveiling the main factors affecting tree recruitment in Portuguese forests, modelling sapling data collected during 5th Forest Inventory, for five Quercus taxa. Zero-inflated count models allowed us to examine simultaneously (i) absence and (ii) density recruitment. Using Akaike weights, we obtained importance values 15 relevant explanatory variables. Results showed that seed availability climatic variables were determinant...
Abstract Quantifying the genetic diversity of riparian trees is essential to understand their chances survive hydroclimatic alterations and maintain role as foundation species modulating fluvial ecosystem processes. However, application suitable models that account for specific dendritic structure hydrographic networks still incipient in literature. We investigate roles ecological spatial factors driving Salix salviifolia , an Iberian endemic tree, across latitudinal range. applied...
Abstract The first attempts to describe species ecological niches were simple geometric procedures that depict the niche boundaries directly from environmental data. convex hull was one of such procedures, popular for its simplicity, clear rational and precise definition niche. However, it lacked ability differentiate areas with different probabilities occurrence according suitability. We incorporate Tukey depth, a mathematical tool measure centrality point within cloud points on...
Abstract Hutchinson's pioneering work on the niche concept, dating from 1957, inspired development of many ecological models. The first proposals, BIOCLIM and HABITAT , were simple geometric approximations to shape niche. Despite their simplicity, they combine two features that make them adequate for purpose exploring niche: fit a predefined empirical data; produce binary or ordinal predictions rather than continuous predictions. Thus, both explicitly delineate precise boundary However,...
In this work we present some syntaxonomic novelties on the vegetation of referred ultramafic outcrops focused onthree new associations: Jonopsidio abulensis-Sedetum maireani, Armerio daveaui-Agrostietum castellanae and Seseli peixotoani-Avenuletum lusitanicae; in addition, a nomenclatural combination an endemic taxon from Morais massif(Armeria langei subsp. marizii) is proposed. We also clarify phytocoenotic structure Portuguese seriesthrough simple diagrammatic representation, which then...
