3. Multilocus phylogeny of arvicoline voles (Arvicolini, Rodentia) shows small tree terrace size

Subject:
divergence, evolutionary history, supertree, supermatrix, phylogenetic tree terrace, Microtus, and Arvicolinae
Language:
English
Description:
We combined mitochondrial (cyb, control region, coi, nd4) and nuclear (irbp, ghr, sry, lcat) DNA sequence data to infer phylogenetic relationships of arvicoline voles. The concatenated supermatrix contained 72.8 % of missing data. From this dataset, Bayesian inference showed close relationships of Arvicola and Chionomys, Proedromys with Lasiopodomys and Microtus gregalis, Phaiomys with Neodon and M. clarkei. Genus Microtus formed a supported group with Blanfordimys and N. juldaschi. The gene partition taxon sets were explained in the multilocus phylogeny in such a way that the resulting Bayesian inference tree represented a unique solution on a terrace in the tree space. This means that although the supermatrix contained a large proportion of missing data, it was informative in retrieving a phylogeny with a unique optimality score, tree likelihood.

4. O rudomořských želvách

Language:

Description:
V Rudém moři se vyskytuje celkem 5 druhů mořských želv, relativně hojněji zde žijí a rozmnožují se kareta pravá (Eretmochelys imbricata) a kareta obrovská (Chelonia mydas). Informace o biologii mořských želv mimo období rozmnožování se získávají složitě a naše poznatky jsou mnohdy útržkovité. Autor přibližuje různé zajímavosti ze života uvedených druhů v Rudém moři u pobřeží Egypta, hlavně o potravní biologii. and Five sea turtle species occur in the Red Sea, among them the Hawksbill Turtle (Eretmochelys imbricata) and the Green Turtle (Chelonia mydas) live and reproduce most frequently. The author presents some remarkable issues surrounding the bionomics of both these marine turtles in the Red Sea along the Egyptian shore, particularly with regard to their feeding ecology.

5. Souboje ještěrek zelených

Creator:
Moravec, Jiří and Kulíková, Helena
Type:
article and TEXT
Language:
Czech
Description:
Ritualizované souboje patří k nejnápadnějším interakcím samečků ještěrek čeledi Lacertidae. V případě ještěrky zelené mají tyto souboje více či méně stereotypní průběh a sestávají se z pěti základních fází. Tyto fáze jsou popsány a fotograficky dokumentovány v případě konkrétní populace ještěrek zelených z blízkého okolí Prahy. and Ritualised combats are the most remark­able male-male interactions in lacertid li­zards. In the Lacerta viridis male-male combats run a more or less stereotypical course consisting of five basic phases. Individual combat phases are described and documented in the case of the wild population of L. viridis living in close vicinity to Prague.

Subject:
mapping squares, species numbers, environmental variables, and PCA
Language:

Description:
The species richness of free-living vertebrates was analysed using mapping of occurrence within individual grid squares (12 x 11.1 km) over the territory of the Czech Republic. The data on species distribution were derived from recent distributional atlases published in the last 15 years, and the records originated mostly in the last 20 years. Altogether, 384 species of cyclostomes, bony fishes, amphibians, reptiles, birds and mammals were included in this study and their presence or absence was recorded in 678 grid squares. The species numbers ascertained in the 523 grid squares situated completely within the Czech Republic varied from 92 to 259 species, with a median of 182 species. The first two principal components explained 44.9 % of the total variance and separated two main habitat gradients based on values of different environmental, topographic, and demographic variables in particular squares. The PC1 represents a gradient from urban habitats at lower altitudes to more homogenous habitats with dominant coniferous forests and meadows situated at higher altitudes. The importance of natural habitats (represented by broad-leaved and mixed forests, as well as by protected areas) and landscape heterogeneity increases along the PC2. Generalized Linear Modelling for each group of vertebrates was fitted using the number of species of individual vertebrate groups as a response variable and the first two principal components as explanatory variables. The species richness of all vertebrate groups except for reptiles is highly dependent on the PC1. The number of fish, amphibian, and bird species in squares decreases with increasing value of the PC1, i.e. it is higher in urban areas at lower altitudes. By contrast, the number of mammal species is higher in uninhabited areas at higher altitudes. The gradient represented by the PC2 is highly significant for species richness of reptiles and mammals, and the number of species of both groups increases with increasing importance of natural habitats.
