Studies in Stylidiaceae: New Taxa, Field Observations, Evolutionary Tendencies

Evolutionary patterns and genetic structure in localized and widespread species in the Stylidium caricifolium complex (Stylidiaceae).

The Stylidium caricifolium (Stylidiaceae) complex consists of seven currently recognized species and a taxon of putative hybrid origin endemic to southwest Western Australia. These taxa vary in geographical distribution from widespread, extending over a range of 500 km, to extremely localized, covering a range of only 0.5 km. Patterns of allozyme variation were investigated in 61 populations co...

New Species of Stylidium, With Comments on Evolutionary Patterns in Tropical Stylidiaceae

Investigating the Role of Land Use on vandalism in Urban Public Spaces

Vandalism is one of the problems of cities today in urban public spaces. Vandalism tendencies are shaped by intrinsic and personality factors. And how the location of the location affects the likelihood of vandalism. Among the landmarks, land use is one of the factors affecting the occurrence of degradation. The role of land use index has been examined under the criterion of land use compatibil...

Diversity of chromosome numbers and meiotic studies in genus Anchusa (Boraginaceae) from Iran (10 Nov 2015)

The present study reports the chromosome number and meiotic behaviour of 14 populationsbelonging to four taxa of Anchusa subgenus Buglossum Gusul. from Iran. All populationsshowed the chromosome number 2n= 4x= 32. It is the first meiotic study for A. subg.Buglossum. We discuss some habit form and evolutionary aspect in the light of cytogeneticdata. The origin of polyploidy (auto-allopolyploidy)...

New Approach for Estimation of Natural and Anthropogenic Components in the Recent Tendencies of Erosion Intensity and Suspended Sediment Yield Changes in River Basins

The offered approach is based on the establishment of the functional dependence between river water discharge (Q) and suspended ms ,in a number of observations, which noticeably differs from the mean value (R) of subsequent allocated period(s). The earliest period anthropogenic component during the subsequent period(s) is the difference between an actual suspended sediment yield and its hypothe...
