The Prediction Of Field Cricket Phonotaxis In Complex Acoustic Environments
(2010-09-24)
Animals detect, recognize and localize relevant objects in noisy, multi-source environments. Female crickets locate potential mates in choruses of simultaneously calling males using acoustic signals, a behaviour termed ...
The Biology Of Two Sexes : A Study Of The Primitively Eusocial Wasp Ropalidia Marginata
(2009-05-21)
A striking feature of hymenopterans societies is the absence of male workers. Foraging, nest building, brood care and all other activities required for the functioning of the colony are carried out by the females. These ...
Tree Diameter Growth : Variations And Demographic Niches In A Tropical Dry Forest Of Southern India
(2009-08-03)
Tree growth influences forest community dynamics and responses to environmental variations, but currently is not well understood. Tree growth in highly diverse wet tropical forests have been well studied and characterised ...
Molecular Ecology of the Primitively Eusocial Wasp Ropalidia Marginata : Relatedness, Queen Succession and Population Genetics
(2018-06-08)
Altruism is defined as a trait in an individual that increases some other individual’s fitness at the expense of her own. Therefore, existence of such traits in a population is an evolutionary paradox, as natural selection ...
Stress Physiology of Free-ranging Asian Elephants (Elephas maximus) : Influence of Ecological and Anthropogenic Stressors
(2018-07-09)
Various ecological and human-induced disturbances play an important role in defining the health of an animal. To cope up with such threats or challenges to its homeostasis, an animal responds by secreting stress hormones ...
Investigating the Impact of Habitat Disturbance and the Role of Functional Traits in a Tropical Butterfly Assemblage
(2018-07-09)
Tropical habitats face a diverse range of anthropogenic threats. Two common and important threats to tropical biodiversity are invasive species and roads. Invasive plants are proposed to be a major threat to biodiversity ...
Sensory Ecology Of Acoustic Communication In The Tropical Bushcricket Genus Mecopoda : Mechanisms And Evolution Of Synchrony
(2009-07-10)
In this thesis, I characterise five species of the bushcricket genus Mecopoda with respect to their acoustic signals and morphology and investigate the phenomenon of acoustic synchrony in one of these five species: Mecopoda ...
Game of Thrones : Direct Fitness through Nest Foundation in the Primitively Eusocial Wasp Ropalidia Marginata
(2018-07-09)
Reproduction is the avenue for gaining direct fitness. But in certain species some individuals do not reproduce, instead gain indirect fitness by helping relatives to reproduce; the prime examples for this come from the ...
Understanding Patterns of Bird Species Distribution in the Western Ghats
(2018-06-23)
Macroecology is the study of relationships between organisms and the environment at large spatial and temporal scales. This field of research examines patterns in species abundance, distribution and diversity. Understanding ...
Queens And Their Succerssors : The Story Of Power In The Primitively Eusocial Wasp Ropalidia Marginata
(2009-04-30)
Ropalidia marginata is characterized as a primitively eusocial wasp due to the absence of morphological differentiation between the queen and worker castes. Unlike other primitively eusocial wasps, however, the queen in ...
