Acoustic Signals, Mate Choice And Mate Sampling Strategies in a Field Cricket
(2017-10-05)
Acoustic communication in orthopterans and anurans provides a suitable model system for studying the evolutionary mechanisms of sexual selection mainly because males use acoustic signals to attract females over long distances ...
Climate Change Mitigation And Adaptation In Indian Forests
(2014-10-10)
Research leading to this thesis aims to assess the policy relevant mitigation potential of Indian forests as well as aims to assess the impact of climate change on carbon stocks, vegetation boundary shifts, Net Primary ...
The Structure And Function Of The Vocal Repertoire Of The Greater Racket-Tailed Drongo (Dicrurus paradiseus) : Insights Into Avian Vocal Mimicry
(2017-07-12)
Sound is used as a medium for communication by taxa as varied as insects, fish, amphibians, birds and mammals. In some birds like the suboscines, song is genetically encoded, whereas in parrots, hummingbirds and oscines, ...
The Distribution, Dynamics & Impacts Of Invasive Lantana Camara In A Seasonal Forest Of Mudumalai, Southern India
(2016-04-25)
Species that become naturalized in a new geographical range, subsequently multiply and spread, and persist to the detriment of resident communities, are known as alien invasive species. Two aspects of species invasion – ...
Divided They Stay : Species Coexistence In A Community Of Mutualists And Exploiters
(2012-12-14)
The fig–fig wasp interaction is a classic example of obligate mutualism and coevolution. It is also a nursery pollination mutualism and supports a diversity of exploiter/parasite/non-pollinating fig wasp species. Mutualists ...
Eco-Hydrology of a Seasonally Dry Tropical Forest : Tree Growth, Belowground Water Dynamics and Drought-Vulnerability
(2017-12-13)
Tropical forests are storehouses of more thanhalf of the world‘s biodiversity and play a key role in global carbon, water and energy cycles. However, as a consequence of rapid anthropogenic climate change, biodiversity and ...
Ecology of Fungus-Farming by Termites : Fungal Population Genetics and Defensive Mechanism of Termites against the Parasitic Fungus Pseudoxylaria
(2018-05-25)
All living organisms require food for growth and survival. Heterotrophs depend on autotrophs such as green plants which can synthesize their own food unlike heterotrophic animals. Among heterotrophs, only humans and some ...
Finding the Way Back Home : A study of Spatial Orientation, Navigation and Homing Behaviour in the Social Wasp Ropalidia marginata
(2018-05-23)
For most of the animals, if not all, finding their way to a particular place is crucial for survival. To address this challenge of way-finding, different animals have evolved with different homing strategies. Social ...
Seed Dispersal In The Tropical Dry Forests Of Mudumalai, Southern India
(2011-06-30)
Plants depend on a wide variety of vectors, both biotic and abiotic, to move their seeds to locations away from parent plants. The stages between seed production and seedling establishment in the plant life cycle are under ...
Call Diversity, Spatio-Temporal Patterning And Masking Interference In An Assemblage Of Acoustically Communicating Ensiferan Species Of A Tropical Evergreen Forest In Southern India
(2011-02-21)
The present study provides the first description of the calls of a multi-species ensiferan assemblage in a tropical evergreen forest of the Indian subcontinent. I have identified and described the calls of twenty ensiferan ...
