Ants, Figs, Fig Wasps : The Chemical Ecology Of A Multitrophic System
(2013-04-01)
Plant–animal interaction systems are complex food webs where the members—plants, pollinators, herbivores, parasites and predators of the pollinators/herbivores—interact with each other in ways which maximize their own ...
Habitat Acoustics And Microhabitat Selection In An Ensiferan Assemblage Of A Tropical Evergreen Forest │
(2013-08-29)
Several animals, both vertebrate and invertebrate, communicate using sound and they do so in a non-ideal medium, the habitat in which they live. As acoustic signals pass through the habitat, they suffer loss of information ...
Systematics And Biogeography Of Scolopendrids Of The Western Ghats, India
(2013-06-25)
In this thesis, the biogeography of the centipede family Scolopendridae of the Western Ghats (WG)was studied. First, a novel limited sampling approach to identify putative Gondwanan origin wherein sampling of was confined ...
Attributes Of Royalty In The Primitively Eusocial Wasp Ropalidia marginata : Pheromone, Ovaries And Behavior
(2012-12-07)
This thesis has looked at the proximate mechanisms by which eusociality is maintained in colonies of the primitively eusocial wasp Ropalidia marginata. Unlike other typical primitively eusocial species, the R, marginata ...
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. ...
Studies On Endocrine And Behavioral Assessment Of Reproductive Status In Asian Elephants (Elephas Maximus)
(2013-01-16)
The Asian elephant (Elephas maximus), a charismatic ‘flagship species’, is threatened by extinction in the wild, and the development of self-sustainable captive populations is a key conservation challenge. A third of the ...
Mate Choice, Mate Sampling And Baffling Behaviour In The Tree Cricket Oecanthus henryi
(2017-07-12)
Among the different sensory modalities that play a role in sexual selection, acoustic
communication plays an important one. Acoustic communication has been known to be
used for male-male competition (territory maintenance, ...
Investigating Pattern Recognition And Bi-coordinate Sound Localization in the Tree Cricket Species Oecanthus Henryi
(2017-09-20)
Acoustic communication, used by a wide variety of animals, consists of the signaler, the signal and the receiver. A change in the behaviour of the receiver after reception of the signal is a prerequisite for communication. ...
Sexual Selection On Elephant Tusks
(2017-06-12)
Darwin was troubled by elaborate male traits observed in many species that are seemingly maladaptive for survival, the peacock’s tail being the most iconic of all. He wrote "The sight of a feather in a peacock’s tail, ...
Fire Ecology of a Seasonally Dry Tropical Forest in Southern India
(2017-10-26)
Fire ecology encompasses the study of the factors, biotic and abiotic, that influence the occurrence of fire in an area, as well as the effects fire has on the flora and fauna native and non-native to the region (Whelan ...
