Predicting the Distribution of Leucanthemum Vulgare Lam. Using Logistic Regression in Fandoghlou Rangelands of Ardabil Province, Iran

Species Distribution Modelling (SDM) is an important tool for conservation planning and resource management. Invasive species represent a good opportunity to evaluate SDMs predictive accuracy with independent data as their invasive range can expand quickly. Thus, the aim of this study was to investigate the relationships between presence of Leucanthemum vulgare Lam. and environmental v...

Formation of unreduced megaspores (diplospory) in apomictic dandelions (Taraxacum officinale, s.l.) is controlled by a sex-specific dominant locus.

In apomictic dandelions, Taraxacum officinale, unreduced megaspores are formed via a modified meiotic division (diplospory). The genetic basis of diplospory was investigated in a triploid (3x = 24) mapping population of 61 individuals that segregated approximately 1:1 for diplospory and meiotic reduction. This population was created by crossing a sexual diploid (2x = 16) with a tetraploid diplo...

The impact of invasive species Leucanthemum vulgare Lam. on vegetation characteristics of Fandoghlou rangelands in Namin county, Ardabil , Iran

Presence of invasive species on rangelands is a degradation sign. The aim of this study was to evaluate the effects of invasive species Leucanthemum vulgare Lam. on the structural and functional characteristics of Fandoghlou rangelands in the Namin county of Ardabil province. The model used for sampling was the stratified random systematic. Two main sites with the presence and absence of L. vul...
