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 ... -
Causes and Consequences of Hetrospecific Foraging Associations in Terrestrial Bird Communities
(2018-04-12)The question of group-living in animals has attracted a lot of research attention. Today, we have a nuanced understanding of ultimate explanations and proximate mechanisms for group-living, as well as the genetic basis for ... -
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 ... -
Climate-Growth Relationships of West Himalayan Fir (Abies pindrow) along an Altitudinal Gradient in Northwestern Himalaya
Climate change which includes an increase in temperature, changes in precipitation, retreating of glaciers, has a significant impact on ecosystem dynamics and the social communities. High mountains around the globe are ... -
Collective escape dynamics of fission-fusion groups in the wild
Collective movement is a fundamental process affecting the survival and reproductive success of group-living animals. Many of the hypothesized benefits of grouping such as predation evasion and foraging efficiency may ... -
Colony Founding And The Evolution Of Eusociality In Primitively Eusocial Wasp, Ropalidia Marginata
(Indian Institute of Science, 2005-08-08)Many animals live in societies of varying degrees of organization. Some individuals in these societies seem to sacrifice their own fitness to increase the fitness of some others. Understanding the forces that mould the ... -
Condition-dependent signalling and mating behaviour in the tree cricket, Oecanthus henryi
Male reproductive success in systems exhibiting sexually selected traits can be driven by male mating effort in sexual signals and in the production of nuptial gifts. Male mating effort can be determined by various biotic ... -
Deciphering the evolutionary ecology of snake venoms and its impact on snakebite therapy in India
Venom, being an adaptive trait, has propelled the expansion of snake lineages across diverse habitats, such as the biogeographically distinct Indian landscapes. Natural selection optimises the potency, composition and ... -
Determinants Of Behavioural And Reproductive Dominance In The Primitively Eusocial Wasp Ropalidia Marginata
(2016-09-15)In societies where all individuals are reproductively totipotent and yet, at a given time only one of them reproduces, it is interesting to examine the factor(s) that may influence and predict who will be the reproductive. ... -
Dispersal Patterns and Processes in Littorinid Snails along the Indian Coastline
Dispersal has important ecological and evolutionary consequences for a species. Marine dispersal is unique because of facilitation by ocean currents, where oceanography interacts with species traits and environmental ... -
Distribution, activity budget and feeding ecology of Himalayan gray langur (Semnopithecus ajax) in Kashmir Himalaya
Colobines are group of primates known to inhabit harsh environments. These habitats pose different challenges which they have coped up physiologically and behaviourally. Primates in such environments are subjected to ... -
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 – ... -
Diversity and distribution of mixed-species foraging groups in the Lakshadweep Islands, India
Species interactions are known to shape biological communities. While antagonistic interactions like competition and predation are well known, cooperative interactions have received comparatively less attention. Mixed-species ... -
Diversity from the Gut to Species: Phylogeny, Population genetics and Microbiome of the Antilope cervicapra
Evolutionary relationships between members of the Antilopina taxon have been much debated in recent years. The ‘true antelope’ clade is currently comprised of 4 genera viz., Gazella, Nanger, Eudorcas and the monotypic genus ... -
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 ... -
Dynamic colour change in Psammophilus dorsalis: role of natural and sexual selection
Overall, the results from this study support the idea that animal signals arise from a balance between increased conspicuousness for social signalling and inconspicuousness to avoid predation risk. Animals that can change ... -
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 ... -
Ecology of predator-prey interactions in the context of mate searching
Animals communicating in the context of mate searching benefit by increasing their likelihood of encountering mates. Mate searching begins the important process of individuals of opposite sexes forming pairs, which is ...
