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 ...
Acoustic Signals, Mate Choice And Mate Sampling Strategies in a Field Cricket
(2017-10-05)
Acoustic communication in orthopterans and anurans provides a suitable model system for studying the evolutionary mechanisms of sexual selection mainly because males use acoustic signals to attract females over long distances ...
The Structure And Function Of The Vocal Repertoire Of The Greater Racket-Tailed Drongo (Dicrurus paradiseus) : Insights Into Avian Vocal Mimicry
(2017-07-12)
Sound is used as a medium for communication by taxa as varied as insects, fish, amphibians, birds and mammals. In some birds like the suboscines, song is genetically encoded, whereas in parrots, hummingbirds and oscines, ...

(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 – ...
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 ...
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 ...
The Role of Nursery Size and Plant Phenology on the Reproduction of and Relationships within a Fig-fig Wasp Nursery Pollination System
(2018-05-09)
Obligate nursery pollination mutualisms such as the fig–fig wasp system, with their central plant–pollinator mutualism associated with non-pollinating satellite wasp species, can function as closed system microcosms ...
