AB  - Paedomorphosis, the presence of ancestral larval and juvenile traits
   that occur at the descendent adult stage, is an evolutionary phenomenon
   that shaped morphological evolution in many vertebrate lineages,
   including tailed amphibians. Among salamandrid species, paedomorphic and
   metamorphic phenotypes can be observed within single populations
   (facultative paedomorphosis). Despite wide interest in facultative
   paedomorphosis and polymorphism produced by heterochronic changes
   (heterochronic polymorphism), the studies that investigate intraspecific
   morphological variation in facultative paedomorphic species are largely
   missing. By quantifying the cranium size and development (bone
   development and remodeling), we investigated the variation at multiple
   levels (i.e., between sexes, populations and species) of two
   facultatively paedomorphic European newt species: the alpine and the
   smooth newt. The pattern of variation between paedomorphs (individuals
   keeping larval traits at the adult stage) and metamorphs (metamorphosed
   adult individuals) varied between species and among populations within a
   single species. The patterns of variation in size and skull formation
   appear to be more uniform in the alpine than in the smooth newt,
   indicating that developmental constraints differed between species (more
   pronounced in alpine than in smooth newt). Our study shows that the
   cranial skeleton provides detailed insight in the pattern of variation
   and divergence in heterochronic polymorphism within and between species
   and open new questions related to heterochronic polymorphism and
   evolution of cranial skeleton.

AB  - A precise knowledge of the spatial distribution of taxa is essential for
   decision-making processes in land management and biodiversity
   conservation, both for present and under future global change scenarios.
   This is a key base for several scientific disciplines (e. g.
   macro-ecology, biogeography, evolutionary biology, spatial planning, or
   environmental impact assessment) that rely on species distribution maps.
   An atlas summarizing the distribution of European amphibians and
   reptiles with 50 x 50 km resolution maps based on ca. 85 000 grid
   records was published by the Societas Europaea Herpetologica (SEH) in
   1997. Since then, more detailed species distribution maps covering large
   parts of Europe became available, while taxonomic progress has led to a
   plethora of taxonomic changes including new species descriptions. To
   account for these progresses, we compiled information from different
   data sources: published in books and websites, ongoing national atlases,
   personal data kindly provided to the SEH, the 1997 European Atlas, and
   the Global Biodiversity Information Facility (GBIF). Databases were
   homogenised, deleting all information except species names and
   coordinates, projected to the same coordinate system (WGS84) and
   transformed into a 50 x 50 km grid. The newly compiled database
   comprises more than 384 000 grid and locality records distributed across
   40 countries. We calculated species richness maps as well as maps of
   Corrected Weighted Endemism and defined species distribution types (i.e.
   groups of species with similar distribution patterns) by hierarchical
   cluster analysis using Jaccard's index as association measure. Our
   analysis serves as a preliminary step towards an interactive, dynamic
   and online distributed database system (NA2RE system) of the current
   spatial distribution of European amphibians and reptiles. The NA2RE
   system will serve as well to monitor potential temporal changes in their
   distributions. Grid maps of all species are made available along with
   this paper as a tool for decision-making and conservation-related
   studies and actions. We also identify taxonomic and geographic gaps of
   knowledge that need to be filled, and we highlight the need to add
   temporal and altitudinal data for all records, to allow tracking
   potential species distribution changes as well as detailed modelling of
   the impacts of land use and climate change on European amphibians and
   reptiles.

AB  - Aim Ecogeographical variation of body size in vertebrates (e.g. Bergmann's rule) has long been recognized. However, the patterns and causes of intra-specific ecogeographical variation of body size in ectotherms, and in amphibians in particular, are strongly debated. We identified the relationship between bioclimatic variables and body size predicted a priori by alternative hypotheses (heat balance, endurance, seasonality, starvation resistance, water availability, primary productivity, parental investment) proposed to explain ecogeographical patterns of body size in ectotherms, and we evaluated the relative support of these hypotheses in explaining variation in body size of the Italian crested newt, Triturus carnifex. Location Twenty-three populations covering the whole range of T. carnifex (Austria, Croatia, Italy and Slovenia). Methods We obtained data on body size (snout-vent length, SVL) of 2639 adult newts from direct measurements and the literature; we obtained high-resolution environmental data for the sampled localities. We used an information-theoretic approach to evaluate the support of the data for the different hypotheses. We also integrated information on population genetics in our models. Results We observed strong geographical variation of body size. The best Akaike information criterion (AIC) models showed that populations with larger body size are associated with cold climates and secondarily with high primary productivity. Furthermore, sexual dimorphism increases in cold climates, as the increase in body size was stronger for females. When taking into account population genetics, we did not find support for relationships with the other variables. Main conclusion Our results are consistent with three hypotheses proposed to explain ecogeographical variation in amphibians: heat balance, increased parental investment of females and productivity. Information theory provides the framework for comparing hypotheses rather than looking for patterns. We suggest that evaluating the support for mechanisms can provide better insights than simply assessing whether ecogeographical variation is in agreement with some 'rule'.

AB  - Facultative paedomorphosis, a process in which newt larvae can opt for reproduction before or after metamorphosis, is geographically heterogeneous. Despite numerous ecological studies and recent evidence of declines in paedomorphic populations, however, no attempt to model environmental variables that explain the presence of paedomorphs has been made at a multi-scale level. Our aim was to fill this gap in studying three newt species (Lissotriton vulgaris, Mesotriton alpestris, and Triturus macedonicus) of the Montenegrin karst as model species. To this end, we used multivariate analysis on three scales of habitat: the breeding pond, the land use and the climatologic features. Results show that the study area is both an important hotspot for paedomorphosis and where intraspecific diversity is quickly disappearing (20-47% extirpation) because of fish introductions. Other habitat variables (water permanency, PH or the habitat origin) were shown to act on paedomorphosis but not consistently across species, confirming complexity of the evolutionary and ecological processes. This study appeals for more long-term and detailed landscape studies of polyphenisms, a neglected but promising topic, to better understand and protect alternative modes of development. Particularly, measures should be taken to identify hotspots of intraspecific diversity at a global scale and stop fish introductions before we reach a point of no-return. (C) 2008 Elsevier Ltd.

AB  - Background: Sexual size dimorphism (SSD) is a key evolutionary feature that has been studied in many organisms. In a wide range of species, this pattern is more complex because of polymorphism within each sex. However, it is not known whether the magnitude and direction of SSD could be affected by alternative developmental trajectories within sexes. Our aim was to test whether an intrasexual polymorphism, facultative paedomorphosis (a process in which the development of somatic and gonadal tissues differs in alternative morphs), could affect SSD variation patterns in European newts. Results: We report here the first evidence that SSD varies depending on the paedomorphic or metamorphic ontogenetic pathway. In species with a consistent female-biased SSD, paedomorphosis decreased the SSD level, but did not affect its direction. In species with moderate female-biased SSD or variable SSD patterns, paedomorphosis changed the magnitude, or both the magnitude and the direction, of SSD. Conclusion: Our study highlights the importance of developmental processes for shaping SSD patterns in populations in which contrasting life-history pathways evolved. European newts express different SSD patterns depending on their developmental pathway (i.e., metamorphosis versus paedomorphosis), as well as their species and population. These findings emphasize the importance of studying alternative morphotypes, which are found in a wide range of animal groups, to understand the evolution of SSD.

In a wide range of species, this pattern is more complex because of polymorphism within each sex. However, it is not known whether the magnitude and direction of SSD could be affected by alternative developmental trajectories within sexes. Our aim was to test whether an intrasexual polymorphism, facultative paedomorphosis (a process in which the development of somatic and gonadal tissues differs in alternative morphs), could affect SSD variation patterns in European newts. Results: We report here the first evidence that SSD varies depending on the paedomorphic or metamorphic ontogenetic pathway. In species with a consistent female-biased SSD, paedomorphosis decreased the SSD level, but did not affect its direction. In species with moderate female-biased SSD or variable SSD patterns, paedomorphosis changed the magnitude, or both the magnitude and the direction, of SSD. Conclusion: Our study highlights the importance of developmental processes for shaping SSD patterns in populations in which contrasting life-history pathways evolved. European newts express different SSD patterns depending on their developmental pathway (i.e., metamorphosis versus paedomorphosis), as well as their species and population. These findings emphasize the importance of studying alternative morphotypes, which are found in a wide range of animal groups, to understand the evolution of SSD.",

AB  - Aim Paedomorphosis is an evolutionary change in which larval structures are retained in adult animals. In newts and salamanders, this heterochronic process is widely represented and concerns the retention of gill slits. We want to find out whether ecological and geographical determinants may be associated with paedomorphosis in the Alpine newt Triturus alpestris. Location Europe. Methods Determination of the main characteristics of all known aquatic sites containing paedomorphic Alpine newt individuals. Results Although metamorphs are common in Europe, paedomorphs are only found at the southern margin of the geographical range of the species: mainly in Italy and in the Balkans. They were recorded in eighty-seven aquatic sites. No single trend was outlined for the analysed ecological parameters of the aquatic and terrestrial habitats (e.g. altitude, maximum water depth, drying and presence of forest). Main conclusions Contrary to the first models of paedomorphosis, the main traits of aquatic and terrestrial habitat do not explain the occurrence of paedomorphs in natural populations. Although they were found in favourable aquatic habitats surrounded by hostile terrestrial landscapes, they also exist in temporary waters located at proximity of appropriate terrestrial environments. These results support models predicting paedomorphosis in varied environments, but require complementary investigations on the costs and benefits of the alternative ontogenetic pathways. On the other hand, the southern limitation of the heterochronic phenomenon suggests a genetic basis for paedomorphosis in the studied species.
