Borkin et al. (2004) Mass occurrence of polyploid green frogs...
The first report of massive triploidy in the territory of Eastern Ukraine. What is described in this article we have come to call the North-Donetsk center of green frog diversity. Copy - here. Borkin L. J., Korshunov A. V., Lada …
Borkin et al. (2005) Mass polyploidy in the hybridogenic complex Rana esculenta
Report on triploids at the First UGO Conference. Copy – here. Borkin L. Ya., Zinenko A. I., Korshunov A. V., Lada G. A., Lytvynchuk S. N., Rozanov Yu. M., Shabanov D. A. Massive polyploidy in the hybridogenetic complex Rana esculenta …
Borkin et al. (2008) On the Southern Boundary of the Distribution of Hybrid Rana esculenta...
A zoogeographic "common grave" from which the most interesting directions for further searches for undescribed populations of pool frogs and edible frogs emerge. Its PDF copy is available here. Borkin L. Ya., Bezman-Moseiko O. S., Mazepa G. A., Zinenko A. …
Maro et al. (2008) Can the developmental conditions of tadpoles Bufo bufo...?
Attempt to understand the ontogenetic strategies of the common toads and a hypothesis about the mechanism of their switching. Pdf of the article here. Maro A. N., Shabanova A. V., Shabanov D. A. Can the developmental conditions of Bufo bufo …
Shabanov (2009) Why dioecious organisms outcompete cross‑fertilizing hermaphrodites
To understand the specifics of green frog reproduction, a classification is needed that delineates the main types of population reproduction characteristic for animals and explains the reasons for transitions from one type of reproduction to another. Here an attempt is …
Usova (2010) Determining Natural Mortality of Sexually Mature Water Frogs
An important paper for understanding the population ecology of frogs. Frogs are by no means precocious creatures... Usova E. E. Determining the natural mortality of sexually mature water frogs (Pelophylax esculentus complex; Amphibia, Ranidae) using skeletochronology // Visnyk of V. …
Kravchenko, Shabanov (2008) Possible pathways of transformation of population systems
The latest version of the “mandala” (mandala – a highly symbolic graphic object of complex structure used as a theme for meditation) with possible transformation pathways of the GPS of green frogs. Its PDF version is available here. Kravchenko M. …
Shabanov et al. (2009) Which green frogs inhabit the Kharkiv region?
Relevant for our group today is the justification of the terminology used in the study of green frogs. In this article we proposed the term GPS (hemiclonal population system) and named the North-Donetsk Center of Green Frog Diversity. Pdf of …
Kravchenko, Shabanov (2010) Levels of biodiversity of the Pelophylax esculentus complex
Theses containing ideas that, I hope, we will further develop. Unfortunately, in this publication everything is very concise and lacks (due to space constraints) the argumentation that would be appropriate here. Kravchenko M. A., Shabanov D. A. Levels of biodiversity …
Kravchenko et al. (2011) Study of the stability of hemiclonal population systems...
A joint article with mathematicians. Studying the GPS model allowed us to draw interesting, in our view, conclusions regarding the stability of biosystems. The article proposes an interpretation of the concept "stability" that is applicable both in mathematics and in …
Kravchenko, Shabanov (2010) Modeling transformations of hemiclonal population systems...
The article that is fundamental to our work with M.K., which contains a description of all the relationships reflected in the green frog GPSS model we use, is essential. Although breaking through the formulas presented in this article is not …
Korshunov (2010) Ecological patterns of distribution of the Pelophylax esculentus complex... (Abstract)
The first (the second belongs to M.A. Kravchenko) dissertation, defended by a member of our working group on frog topics A.V. Korshunov, examines the ecological patterns of distribution of the Pelophylax esculentus complex in habitats of the upper flow basin …
Shabanov et al. (2006) Study of population systems of green frogs in Kharkiv region
Although the article presented here retains some interest, at least for its authors, the terminology requires correction. Ideas about the possible pathways of change in population systems have been refined, and certain concepts and even species names have changed. In …
Shabanov, Lytvynchuk (2010) Green Frogs: Life Without Rules or a Special Path of Evolution?
Here I post, in the form most convenient for on-screen reading, an article that is our main introduction to the problem of studying green-frog hybridization. This is a review prepared together with Spartak Lytvynchuk for the Russian journal "Priroda": Shabanov …
