climate change

Redistribution of habitats between the Sand lizard (Lacerta agilis) and the Common lizard (Zootoca vivipara) in the southern taiga subzone. Reaction to temperature rise or result of processes not related to climate change?

Main observations were made in a sample plot (by 10 km2) during 1999–2023. In 1999 about 40% of the sample plot was arable lands. In 2000–2003 the ploughing had been stopped. In sandy patches, former arables began to be replaced by heathlands with xerophytic grass and sparse sprouts of pine. In 1999–2005 Z. vivipara inhabited the outer edges of floodplain forest with high density; L. agilis distribution was restricted to small patch (about 25 ha) of drained peatland located 4 km away from floodplain forest. Since 2006 L.

Reproductive ecology of Anuran Amphibians: Effects of internal and external factors

Authors: Ivanov G. A., Yermokhin M. V., Tabachishin V. V., Tabachishin V. G.

This research paper examines the influence of internal factors (female body weight, body condition) and external ecological factors on the reproductive parameters of females, as well as on the reproductive ecology of adult individuals of anuran amphibians. Among the most significant reproductive characteristics of females are the number of eggs in a clutch, the proportion of reproductive products to female body weight (contribution to reproduction), and the average weight of eggs.
