Distribution, morphology and habitats of Elatine triandra (Elatinaceae) in Europe, with particular reference to the central part of the continent
Acta Botanica Gallica 1-13.
AbstractElatine triandra Schkuhr is the most variable and widespread species within the genus Elatine L.; it has been recorded in all continents, except Antarctica, but it is mainly located in Europe. The study is based on an extensive data set of European literature, herbaria and web data that covers the period 1828–2012. The range of the species in Europe is disjunctive, covering the southern and western parts of the Central European Plain and the southern part of the Fennoscandian Shield. At a smaller scale, the species can also be found along some river valleys. In Central Europe many localities, particularly isolated ones in the northern part of the range, are now only historical. From the data set we determined that E. triandra may be best observed between May and October. We found that species records show a near-significant shift since 1828. Depending on the environmental conditions, individuals of the taxon develop as one of two morphs: terrestrial or aquatic. The aquatic morph is characterized b...

Chrysolina fastuosa (Scopoli, 1763) is a widely distributed chrysomelid beetle in Europe. According to the literature C. fastuosa has been found in association with Lamiaceae plants such as Ballota nigra L., Galeopsis pubescens Besser, Lamium album L. and Urtica dioica L. (Urticaceae). Host plants have been referred often merely on plant genus level and many authors listed host plants for C. fastuosa which taxonomically differed significantly from one another. In spite of many references which mention consumption and/or association of Ch. fastuosa on stinging nettle, the author has almost never observed the beetle on Urtica species. This paper presents results of two laboratory experiments showing feeding prefer- ence of C. fastuosa adults concerning some Lamiaceae (B. nigra, Lamium purpureum L. and Lamium amplexicaule L.) but not on U. dioica. B. nigra seems to be one of the most preferable host plant species under natural and experimental conditions. Key

Molecules and models indicate diverging evolutionary effects from parallel altitudinal range shifts in two mountain Ringlet butterflies
Biological Journal of the Linnean Society 112(3) 569-583.
Quaternary climatic oscillations caused severe range expansions and retractions of European biota. During the cold phases, most species shifted to lower latitudes and altitudes, and expanded their distribution range northwards and to higher elevations during the warmer interglacial phases. These range shifts produced contrasting distribution dynamics, forming geographically restricted distribution patterns but also panmictic distributions, strongly dependent on the ecologic demands of the species. The two closely related butterfly species Erebia ottomana Herrich-Schäffer, 1847 and Erebia cassioides (Reiner & Hohenwarth, 1792) show subalpine and alpine distribution settings, respectively. Erebia ottomana is found up to the treeline (1400–2400 m a.s.l.), whereas E. cassioides reaches much higher elevations (from about 1800 m a.s.l. in the Retezat Mountains, in Romania, to 2800 m a.s.l.). Thus, both species cover diverging climatic niches, and thus might also have been distributed differently during the cold glacial stages. Individuals of these two species were sampled over the mountain areas of the Balkan Peninsula and genetically analysed using allozyme electrophoresis. Additionally, we performed species distribution models (SDMs) to simulate the distribution patterns of both species in the past (i.e. during the Last Glacial Maximum and the Atlanticum). Our genetic data show contrasting structures, with comparatively low genetic differentiation but high genetic diversity found in E. ottomana, and with stronger genetic differentiation and a lower level of genetic diversity, including many endemic alleles, occurring restricted to single mountain massifs in E. cassioides. The SDMs support a downhill shift during glacial periods, especially for E. ottomana, with possible interconnection among mountain regions.We conclude that during the cold glacial phases, both species are assumed to shift downhill, but persisted at different elevations, with E. ottomana reaching the foothills and spreading over major parts of the Balkan Peninsula. In contrast, E. cassioides (the truly alpine species) survived in the foothills, but did not reach and spread over lowland areas. This more widespread distribution at the Balkan Peninsula of E. ottomana compared with E. cassioides is strongly supported by our distribution models. As a consequence, long-term geographic restriction to distinct mountain massifs in E. cassioides versus panmixia in E. ottomana produced two contrasting evolutionary scenarios.

The distribution of the crested and marbled newt species (Amphibia: Salamandridae: Triturus) – an addition to the New Atlas of Amphibians and Reptiles of Europe
Amphibia-Reptilia 35(3) 376-381.
In the recently published New Atlas of Amphibians and Reptiles of Europe (Sillero et al., 2014a), the distribution of the newt genus Triturus was not resolved at the level of the species. The main reason for this was the lack of high quality distribution data from in and around the parapatric contact zones between species, where interspecific hybridization occurs. We are working extensively on Triturus and the (particularly genetic) data we have accumulated allow us to map the individual Triturus species at the appropriate scale. We here provide a database composed of distribution data for the individual species, at generally high resolution, particularly from in and around contact zones. Based on this database we produce maps at the 50 × 50 km UTM grid resolution as used in the new atlas and highlight those grid cells in which more than one Triturus species occurs.

Effect of geographic background and equilibrium state on niche model transferability: predicting areas of invasion of Leptoglossus occidentalis
Biological Invasions 16(5) 1069-1081.
Niche conservatism providing support for using ecological niche modeling in biological invasions has been widely noticed, however, the equilibrium state and geographic background effect on niche model transferability has received scant attention. The western conifer seed bug, Leptoglossus occidentalis, native to western North America, has expanded its range eastward and has become an invasive pest in Europe and Asia. Niche models calibrated on the ranges of a small native population and two large expanding populations were compared. We found that the climate niche of L. occidentalis is conserved during its steady expansion in North America and rapid spread in Europe. Models based on the small western native range successfully captured the eastern expanding and introduced European populations, whereas the large area-based models varied with the presumed state of equilibrium. The equilibrium state based model succeeded but the non-equilibrium based model failed to predict the range in Europe. Our study estimates global invasion risk zones for L. occidentalis and suggests that, based on niche conservatism, modeling based on a reasonable geographic distribution at a climatic equilibrium of a species could guarantee the transferability of niche model prediction. Caution is warranted in interpreting low niche model transferability with niche differentiation and forwarding message for management strategy.
