I’ve done my research during the years 2015-2016. During my research I’ve
done my measurements in March-June 2016 and August-October of the same
year. Through my measurements I intruded to gain sight upon the dimensions of
the amphibian fauna. During my fieldworks I examined and followed the
movements and behaviour of the common frog (Rana temporaria), yellow-bellied
toad (Bombina variegata), common toad (Bufo bufo) and newt species (Triturus
sp.). Because the habitats are in a constant alteration – and this phenomenon
affects the dimensions of the amphibians population – I would like to continue my
work in the future to find solutions that could help to curb the decay of the
habitats.
The methods useb by me to estimate the dimensions of the population are: -
the head’s counting and the spawn counting and like this. I draw a conclusion
upon the intra-racial abundance and spawn-frequency. I’ve used the Microsoft
Excel (vers. 2010) to process, systematize and to edit diagrams while for map
redaction I’ve used the Google Earth application.
The number of the wetlands investigated by me is 14 and on 10 out of these 14 I could find signs of
spawnings. Based my measurements I can say that – from the growth’s point of view – the amphibians
are using most frequently the puddles.

Absolute abundancy
Through my measurements I evidenced that the most frequently met races on the examined habitats
are the newt species (absolute abundance is 10 while the other races have an average of 0,19 abs.
absolute abundace.)
Based on theoretical literature I draw the conclusion that during the years 2005-2010 the
amphibians have had more habitats at their disposal (Demeter et. al 2011) than today on the territories
chosen by me to examinate – this stands out from the number of the camplings. Ergo the habitats are
disappearing.
My hypotesis that the habitats are disappearing is being confirmed following
ny neasurements and their comparation with the theoretical literature. It is an
important that the next generation to be able for recognizing the most minute
values because for a landscape with large biodiversity the amphibians a way
important part because they are the building blocks of the mosaic landscape.
The diminuation of the habitats is not affecting only the amphibians
population but has a negative effect on other animal population. The value
destruction of this type can be controlled only by making the people conscious
about the importance of theese values and their importance for the future.
