Objectives and goals
Objective of this Master’s thesis is to expand
our understanding of the biology of one of
the most poorly studied species of rodents the forest-steppe marmot (M. kastschenkoi).
The object of the study is the forest-steppe
marmot (M. kastschenkoi) in sub taiga zone
of western Siberia (Tomsk region).
The subject of the study is the biology and
some of its peculiarities of M.kastschenkoi.
● Goals:
1. explore three found colonies of the forest-steppe marmot, create a map of the location of
burrows and colonies;
1. identify the number of marmots in each colony and the structure of their families;
2. use camera traps and in field observations to identify the daily activity of marmots;
3. identify threats to this species.

Material and methods
Material was collected in the period from 04.10.2022 to
20.05.2024, during spring and summer months.
Colonies were explored by using route-visual method, data
was collected with Garmin GPS navigator. 3 colonies were
discovered, with a total of 166 burrows.
QGIS software was used for GPS data analyzing and
creating maps.
The nonparametric Mann-Whitney test in the Statistica 8.0
program was used to identify statistical differences in
distances between burrows within families and between
individual families

Material and methods
Camera traps (9 pieces) were used for analyzing daily activity and family structure.
Field observation method was carried out with binoculars, from observation points and a distance of 30100 meters.
In total, we completed 6 days of field observations and 21 day of observations using a camera trap.

The distanses between intrafamily burrows were
significantly lower than distances between families
(Z = -2.12; P<0.05).
This family of forest-steppe marmots consists of
the adult male and female and two-year-olds
(juvenile) and underyearlings (pups of the year).

Recommendations
Conduct a fundamental research about the degree of influence of anthropogenic factors on the
habitat of animals, taking into account disturbance factors.
Find out the reasons for the increase or decrease in morbidity, birth rate, mortality and the
influence of all these processes on the age-sex structure of populations and on the number of
animals.
Strengthen actual protection and ensure strict compliance with the protective regime in all studied
territories, especially in “Bank slope of the Tom River” reserve to reduce the anthropogenic load
on these area.
Pay great attention to the ban on enduro motorcycles and ATVs in all these protected areas.
Refrain from developing gold deposits in the territory of the Larinsky reserve or on its borders.
