Приказ свих података о документуАпстракт:
One long-term studied local population of Bufo bufo situated in the outskirts of
southeastern Belgrade (Serbia) was assessed for changes in body size and age over a
17 years period, at different moments: A (2005: n=47), and B (2013-2014: n=74) for
females, and A (2005: n=94), B (2013-2014: n=151) and C (2020-2021; n=302) for
males. The snout-vent length of the females did not change over time (Mann Whitney
U: Z=-0.89; p>0.05), but their body mass was higher in moment B (Mann Whitney U:
Z=-4.7; p<0.05). The snout-vent length of the males increased over the study period
(Kruskal-Wallis: Chi-sq=26.82; p<0.05), but their body mass remained similar
(Kruskal-Wallis: Chi-sq=26.82; p>0.05). We observed a sexual dimorphism, females
being larger than males (SD =1.31, Mann Whitney U: Z=-16.08; p<0.05). The median
age increased over time in both females (moment A - 4 years old; moment B - 5 years
old; Mann Whitney U; Z=-6.97; p<0.05), and males (moment A - 4 years old, B - 5 years
old, C - 5 years old, Kruskal-Wallis: Chi-sq=40.68; p<0.05). Age of sexual maturity (i.e.,
minimum age observed) remained similar over the study period in both females (3
years old) and males (2 years old). Longevity (i.e., maximum age observed) increased
over the study period, from 6 to 7 years old in females, and from 6 to 9 years old in
males. We revealed positive changes in both body size and age of the studied
population over a 17-years period of monitoring. Thus, our study provides a baseline
that will help monitor and quantify the impact of habitat changes that were only
recently observed in the area (i.e., deforestation, since 2019).
