MAXENT is now a common species distribution modeling (SDM) tool used by conservation practitioners for predicting the of from set records and environmental predictors. However, datasets occurrence to train model are often biased in geographical space because unequal sampling effort across study area. This bias may be source strong inaccuracy resulting could lead incorrect predictions. Although number correction methods have been proposed, there no consensual guideline account it. We compared...
Aim Studies of environmental niche shift/niche conservatism that are based on species distribution modelling require a quantification purity and potential overlap. Although various metrics have been proposed for this task, no comparisons their performance available yet express the linearity range shifts error-proneness. Herein, we assess six overlap using three sister pairs plethodontid salamanders as well artificial to test curves, impacts varying sizes study area sizes. Location North...
ABSTRACT Aim The use of ecological niche models (ENMs) to predict potential distributions species is steadily increasing. A necessary assumption that climatic niches are conservative, but recent findings shifts during biological invasion indicate this not always valid. Selection predictor variables may be one reason for the observed shifts. In paper we assess differences in native and invaded ranges Mediterranean house gecko ( Hemidactylus turcicus ) terms commonly applied climate ENMs. We...
Background Species Distribution Models (SDMs) aim on the characterization of a species' ecological niche and project it into geographic space. The result is map potential distribution, which is, for instance, helpful to predict capability alien invasive species. With regard species, recently several authors observed mismatch between distributions native ranges derived from SDMs and, as an explanation, shift during biological invasion has been suggested. We studied physiologically well known...
Species are being lost at increasing rates due to anthropogenic effects, leading the recognition that we witnessing onset of a sixth mass extinction. Emerging infectious disease has been shown increase species loss and any attempts reduce extinction need squarely confront this challenge. Here, develop procedure for identifying amphibian most risk from effects chytridiomycosis by combining spatial analyses key host life-history variables with pathogen's predicted distribution. We apply our...
Abstract The amphibian fungal disease chytridiomycosis, which affects species across all continents, recently emerged as one of the greatest threats to biodiversity. Yet, many aspects basic biology and epidemiology pathogen, Batrachochytrium dendrobatidis ( Bd ), are still unknown, such when from where did emerge what is its true ecological niche? Here, we review ecology evolution in Americas highlight controversies that make this so enigmatic. We explore factors associated with variance...
Abstract Anthropogenic global climate change has already led to alterations in biodiversity patterns by directly and indirectly affecting species distributions. It been suggested that poikilothermic animals, including reptiles, will be particularly affected large‐scale reptile declines have observed. Currently, half of the world's freshwater turtles tortoises are considered threatened with extinction, may exacerbate these declines. In this study, we assess how chelonian richness near future....
An integrative taxonomic approach based on morphology, molecular analyses, and climatic niche modeling was used to uncover cryptic diversity in the phyllodactylid gecko species Phyllodactylus reissii. At least three distinct could be identified among examined specimens from southern Ecuador northern Peru. magister, described by Noble (1924) arid Andean valleys of Chinchipe Marañón rivers Peruvian Department Cajamarca synonymized with P. reissii Dixon & Huey (1970) is elevated synonymy a...
Abstract Most of Earth's biodiversity is found in 36 hotspots, yet less than 10% natural intact vegetation remains. We calculated models projecting the future state most these hotspots for year 2050, based on climatic and agroeconomic pressure. Our project an increasing demand agricultural land resulting conversion >50% remaining about one third all 2–6 from This confirms that, short term, habitat loss greater concern climate change their biodiversity. Hotspots are severely threatened...
Abstract Aim We introduce a high‐quality global database of established alien amphibians and reptiles. use this data set to analyse: (1) the distribution; (2) temporal dynamics; (3) flows between native ranges; (4) key drivers Location Worldwide. Methods collected geographical records reptiles from thorough search across wide number sources. supplemented these with year first record, when available. used descriptive statistics visualization techniques analyse taxonomic, spatial patterns in...
Abstract Climate change impacts biodiversity and is driving range shifts of species populations across the globe. To understand effects climate warming on biota, long-term observations occurrence detailed knowledge their ecology life-history crucial. Mountain particularly suffer under often respond to environmental changes by altitudinal shifts.

Abstract Habitat change and fragmentation are the primary causes of biodiversity loss worldwide. Recent decades have seen a surge funding, published papers citations in field as these threats to continue rise. However, how research directions agenda evolving this remains poorly understood. In study, we examined current state on habitat (due agriculture, logging, fragmentation, urbanisation roads) pertaining two most threatened vertebrate groups, reptiles amphibians. We did so by conducting...
The disease chytridiomycosis, caused by the fungus Batrachochytrium dendrobatidis (Bd), has dramatic amphibian population declines and extinctions in Australia, Central North America, Europe. Bd is associated with >200 species of amphibians, but not all that become infected are susceptible to disease. Specifically, rapidly emerged some areas world, such as USA, throughout South causing collapse. mechanism behind rapid global emergence poorly understood, part due an incomplete picture...
While traditionally species recognition has been based solely on morphological differences either typological or quantitative, several newly developed methods can be used for a more objective and integrative approach delimitation. This may especially relevant when dealing with cryptic complexes, where high overall resemblance between is coupled comparatively variation within populations. Rock lizards, genus Darevskia, are such an example, as many of its members offer few diagnostic features....
The climate warming of the postglacial has strongly reduced distribution cold-adapted species over most Central Europe. Such taxa have therefore become extinct lowlands and shifted to higher altitudes where they survived present day. lycaenid butterfly Lycaena helle follows this pattern former widespread later restriction mountain areas such as European middle mountains. We sampled 203 individuals from 10 populations representing six ranges (Pyrenees, Jura, Massif Central, Morvan, Vosges...
Studies of Hordeum vulgare subsp. spontaneum, the wild progenitor cultivated barley, have mostly relied on materials collected decades ago and maintained since then ex situ in germplasm repositories. We analyzed spatial genetic variation barley populations rather recently, exploring sequence variations at seven single-copy nuclear loci, inferred relationships among these toward genepool crop. The collection covers whole natural distribution area from Mediterranean to Middle Asia. In contrast...
By altering or eliminating delicate ecological relationships, non-indigenous species are considered a major threat to biodiversity, as well driver of environmental change. Global climate change affects ecosystems and communities, leading changes in the phenology, geographic ranges, population abundance several species. Thus, predicting impacts global on current future distribution invasive is an important subject macroecological studies. The African clawed frog (Xenopus laevis), native South...
