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 ...
Urbanisation and Shifting Phenotypes Behavioural, Physiological and Cognitive Strategies of the Indian Rock Agama Psammophilus Dorsalis
(2018-07-09)
Humans directly or indirectly cause changes in the environment, and urbanisation is currently one of the most important threats to biodiversity. Urbanisation exposes organisms to novel pressures that are drastically different ...
For Queen and Country : Reproductive and Non-Reproductive Division of Labour in the Primitively Eusocial Wasp Ropalidia Cyathiformis
(2018-07-05)
Division of labour is a hallmark of eusocial insects and is believed to be a major factor in their evolutionary success and ecological dominance. Division of labour can be of two kinds
– reproductive division of labour ...
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. ...
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. ...
