Abstract— Termites work together to modify their surroundings, which in turn influences their behaviour,
leading to the building of termite mounds. The study was designed to assess diversity of termite mounds
present in the Bangalore University Campus, Bengaluru, India. Observations were made on the occurrence,
abundance, evenness and richness of the termite mounds. Mounds were surveyed by field survey and
photographic interpretation method during July 2021 to June 2022. Totally 119 mounds were found, out of
which 18 are ground level mounds, 42 small mounds, 37 medium mounds and 22 tall mounds. To test its
effectiveness and to know about the influence of the mounds on the ecological well-being, termite mounds
were identified, compared and interpreted using google earth map and the results were statistically verified.
Keywords— Termites, Mounds, Diversity Index, Richness index and Evenness index.
I. INTRODUCTION
Termites being eusocial insects are spread widely in sub-
tropics and tropics specially playing key role as
decomposers and engineers of soil [13, 16]. Termite are
having very soft cuticle, they do not sustain in cold regions,
their nests are formed by uniform thermal envelope with
very hard outer shell for protection from predators and
desiccation [33]. Termites feed on various kinds of organic
matter such as dead organic materials, wood, cardboard,
paper etc [15]. Thus, they contribute much to nutrient cycle
and community structuring in any ecosystem [32]. Along
with ants and earthworms, the termites play a major role in
increasing porosity of soil and creates tunnels which are
called mounds. mounds are solid but porous walls made
from soil and termite faeces acting as niche for various
microorganisms and fauna providing protection against
changing environment [10, 20, 27, 34].
The degree of termite contribution for the spatial
heterogeneity in an ecosystem is attached with the mounds’
spatial distribution per unit area and its size and number.
The spatial distribution of mounds is still the concept of
debate as emphasized by findings from various ecosystems
[5, 18, 19, 22, 30, 35]. Earlier studies of mounds are uneven,
focusing on species classification [1] nest building and
foraging activities [2] nutrient cycling [17] and termite-
herbivore interactions [39]. However, understanding the
spatial distribution of termite mounds can be a key
component in predicting habitat utilisation and forage for
herbivores [11, 12, 24]. Hence the present study was
undertaken.
II. METHODOLOGY
The present study was carried out in Jnanabharathi campus
(13º 05” N and 77º 34” E) at an altitude of 924 meters above
the mean sea level with annual rainfall range of 530 mm to
1375 mm (mean 916 mm) spread to an area about 4.5 sq.km
(1100 acres), situated on the elevated plateau at the western
side of Bangalore, Karnataka, India. The study area is
divided into site 1 (North) and site 2 (South) and is partially
inhabited (Fig 1). The major part being un-inhabited,
possesses wide range of vegetation from scrubby jungle,
wild to cultivated trees with fauna such as insects, toads,
reptiles, rodents and birds with a high population of termites
and snakes.
