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 ... -
The influence of landscape composition on butterfly populations: A behavioural ecological approach
Overall, taking behavioural ecological and trait-based approaches, my study suggests that the distribution of a species and patterns in its population densities in a landscape are affected by diverse ecological variables, ... -
Intrasexual competition in females of a socially polygynous lizard, Psammophilus dorsalis
Competition between individuals of the same sex, intrasexual competition, has received much attention in males, mainly because such competition, which is primarily for mates (i.e. sexual selection), often selects for ... -
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 ... -
On Trait Evolution in a Heterogeneous Environment: Oviposition Site Selection in a Mosquito in Response to Multiple Risk Factors
A focus in evolutionary biology is to understand the drivers of diversity in animal behavioural traits in the living world. Animals facing similar problems in the environment, such as the problem of how much to invest in ... -
Resource allocation patterns and strategies in the mutualism between figs and fig wasps
Mutualism involves exchange of services and rewards between the partners, resulting in a net benefit to all those involved. In many mutualisms, hosts are larger partners that interact with several individuals of smaller ... -
Territorial and mating strategies of males in a lekking population of blackbuck Antilope cervicapra
Territoriality associated with lek-mating systems is unique in that males defend small, heavily clustered territories that lack resources usually thought to attract females, such as food and water. Females visit these male ...
