Article
Full-text available
The Mediterranean Sea is recognized today as the World’s most invaded marine region, but observations of species occurrences remain scattered in the scientific literature and scarcely accessible. Here we introduce the ORMEF database: a first comprehensive and robust compilation of exotic fish observations recorded over more than a century in the Me...
Article
Mediterranean marine protected areas (MPAs), designed to achieve long-term nature conservation, are progressively conquered by invasive species of tropical origin, posing novel challenges for managers and policymakers of the 21st century. In this study, we assessed the vulnerability of 142 coastal Mediterranean MPAs to nine of the most invasive fis...
Article
The development of approaches to predict the distribution and potential expansion of invasive species is still an open challenge. Here our goal is to improve the modelling procedure for marine invaders by coupling Species Distribution Models (SDMs) with an analysis of their univariate niche dynamics. In particular, we tested for the first time whet...
Article
Full-text available
Approaches to predicting species assemblages through stacking individual niche‐based species distribution models (S‐SDMs) need to account for community processes other than abiotic filtering. Such constraints have been introduced by implementing ecological assembly rules (EARs) into S‐SDMs, and can be based on patterns of functional traits in commu...
Article
Full-text available
Protected areas (PAs) play a critical role in conserving biodiversity and maintaining viable populations of threatened species. Yet, as global change could reduce the future effectiveness of existing PAs in covering high species richness, updating the boundaries of existing PAs or creating new ones might become necessary to uphold conservation goal...
Article
Full-text available
The prevailing method for estimating the potential impact of future climate change on biological communities is to stack binary predictions from species distribution models (binary stacked species distribution models, bS-SDM). However, it has been argued that bS-SDM may overestimate species richness and, hence, community composition. Alternative ap...

Full-text available
Context Current shifts in biodiversity are driven by multiple processes of environmental and landscape change. Particularly, land use/land cover (LU/LC) dynamics are among the major drivers of biodiversity loss worldwide. Objectives In this study we aim to explore the applicability of a new modelling framework to predict top predators’ responses t...
Article
1.The popularity of species distribution models (SDMs) and the associated stacked species distribution models (S‐SDMs), as tools for community ecologists, largely increased in recent years. However, while some consensus was reached about the best methods to threshold and evaluate individual SDMs, little agreement exists on how to best assemble indi...

1.The combined effects of climate change and other factors, such as land use change or fire disturbance, pose daunting challenges for biodiversity conservation worldwide. 2.We predicted the future effectiveness of the Natura 2000 (N2000), the current network of protected areas (PA) in Europe, at maintaining and representing suitable environmental...
Article
A key focus in ecology is to search for community assembly rules. Here we compare two community modelling frameworks that integrate a combination of environmental and spatial data to identify positive and negative species associations from presence-absence matrices, and incorporate an additional comparison using joint species distribution models (J...
Article
Full-text available
Community-level climate change indicators have been proposed to appraise the impact of global warming on community composition. However, non-climate factors may also critically influence species distribution and biological community assembly. The aim of this paper was to study how fire–vegetation dynamics can modify our ability to predict the impac...
Article
In this study, we compare two community modelling approaches to determine their ability to predict the taxonomic, functional and phylogenetic properties of plant assemblages along a broad elevation gradient and at a fine resolution. The first method is the standard stacking individual species distribution modelling (SSDM) approach, which applies a...
Article
Full-text available
The aim of the ecospat package is to make available novel tools and methods to support spatial analyses and modeling of species niches and distributions in a coherent workflow.

Full-text available
Community-based climate change indicators have been proposed to reflect the impacts of global warming on community composition. However, factors other than climate, e.g. habitat characteristics or fire disturbance, may also have a critical influence in the distribution of species and the assembly of biological communities. Here we investigated how...
Chapter
An assemblage is a group of species co-occurring at one spatial location at one point in time. They are a central object of study for ecologists. There are a few important commonly measured properties of organisms (eg, body mass, energy flux, functional traits such as leaf mass per unit area) and properties of species (eg, abundance and range size)...

Written by current and former members and collaborators of the ecospat group of Antoine Guisan, Department of Ecology and Evolution (DEE) &...
Article
A fundamental goal of ecological research is to understand and model how processes generate patterns so that if conditions change, changes in the patterns can be predicted. Different approaches have been proposed for modelling species assemblage, but their use to predict spatial patterns of species richness and other community attributes over a ran...
Article
Full-text available
Global environmental changes challenge traditional conservation approaches based on the selection of static protected areas due to their limited ability to deal with the dynamic nature of driving forces relevant to biodiversity. The Natura 2000 network (N2000) constitutes a major milestone in biodiversity conservation in Europe, but the degree to w...
Article
The amphibian micronucleus test has been widely used during the last 30 years to test the genotoxic properties of several chemicals and as a tool for ecogenotoxic monitoring. The vast majority of these studies were performed on peripheral blood of urodelan larvae and anuran tadpoles and to a lesser extent adults were also used. In this study, we de...

Article
The current challenge in a context of major environmental changes is to anticipate the responses of species to future landscape and climate scenarios. In the Mediterranean basin, climate change is one the most powerful driving forces of fire dynamics, with fire frequency and impact having markedly increased in recent years. Species distribution mod...
Article
AimModelling species distributions at the community level is required to make effective forecasts of global change impacts on diversity and ecosystem functioning. Community predictions may be achieved using macroecological properties of communities (macroecological models, MEM), or by stacking of individual species distribution models (stacked spec...
Article
Many studies have provided evidence that prey adjust their behaviour to adaptively balance the fitness effects of reproduction and predation risk. Nocturnal terrestrial animals should deal with a range of environmental conditions during the reproductive season at the breeding sites, including a variable amount of natural ambient light. High degrees...

Full-text available
Although attention on crayfish diseases has recently proliferated, the focus is mainly on a single host-parasite relationship rather than analyzing the entire mycoflora, probably due to the fact that (1) some diseases are occasional (pathogens of which are of difficult collection) and (2) economic impact is more relevant in aquaculture (i.e., a con...
Article
Aim We address the unexplored question of whether the lack of information on intra‐specific diversity inherent in species‐level niche modelling might bias evaluation of the conservation requirements of species and phylogeographic lineages under changing climates. We test for directional biases that might arise due to these methodological difference...

Amphibians are an important and imperiled component of biodiversity. In this study we analyze the efficacy of Italian reserve network for protecting multiple amphibian species in a climate change scenario, considering both nationally designated areas and Natura 2000 sites. Our approach is based on ensemble niche modeling estimate of potential range...
Article
Full-text available
Several studies have observed that taxa below the level of species can vary in the degree to which they differ from one another in the environmental space they occupy. These patterns of within-species niche variation raise the question of whether these differences should be considered when developing models for predicting the potential effects of c...

Global change poses daunting challenges for biodiversity conservation. The Natura 2000 network constitutes the cornerstone of current conservation strategies. However, the degree to which it will be able to meet its conservation objectives under changing conditions in the future remains a major question. My Post-doctoral (CONS_BIOREC) project, funded by Autonomous Goverment of Galicia, aims at developing a multi-scale protocol wherein remote sensing, correlative and process-based models, scenario planning and spatial prioritization tools will be combined to provide a guidance to decision makers for the Natura 2000 network in Iberian Peninsula. To do so, cost-effective ecosystem monitoring and modelling protocols will be developed to forecast the combined effects of the main drivers of global change (climate change, land-use change, and fire disturbance) on biodiversity within the Natura 2000 network under future socio-ecological scenarios. Conflicting conservation perspectives (e.g. Rewilding, 'fire smart' strategies, High Nature Value farmlands) will be strategically applied to seek 'win-win' solutions for conservation of species and habitats vs. providing ecosystem services and functioning, and thus gain insights in future conservation practices to face global change.
