Alternative reproductive tactics (ARTs) are discrete phenotypes employed by individuals of either sex within a species to maximize their reproductive success in varying social and environmental conditions. These tactics often involve different ways of competing for mates or different tactics for parental investment. Conditional ARTs are a class of ARTs where individuals express an ART depending on an extrinsic or intrinsic cue. The fitness of conditionally expressed ARTs may not necessarily be equal for their persistence. However, there exists a class of conditional ARTs called reversible or flexible ARTs wherein individuals reversibly switch between ARTs in response to a cue. In systems which show flexible ARTs, selection could favour genotypes that gives rse to ARTs that have similar fitness. By virtue of the similarity in mating benefits amongst ARTs, individuals can seamlessly switch between ARTs depending on cues without necessarily incurring fitness losses. My thesis attempts to evaluate the mating benefits as a fitness component of flexible ARTs in Oecanthus henryi. Oecanthus henryi is a tree cricket found in the scrublands of the Indian sub-continent. O. henryi males flexibly adopt three different ARTs to obtain mates. Males can either call to attract females or remain silent. Males can adopt a third tactic, called baffling, wherein males call through a hole they make near the centre of a leaf on their host plant. Baffling is known to amplify the call of a male. In the first chapter of my thesis, I used data from a previously conducted mesocosm experiment to study the expression and mating success of calling and silent ARTs under varying predation risk from their natural predator, the green lynx spider (Peucetia viridans). The findings of the study showed that males were equally likely to call or remain silent on a night and the mating successes of both the ARTs were similar across a steep predation gradient. The similarity in mating success across varying ecological contexts may allow individuals to switch between them without incurring mating related costs. Furthermore, silent males were more likely to aggregate around other callers than callers themselves and obtained a majority of their matings by doing so, which suggests that silent males employ satellite behaviour. In the second chapter of my thesis, I explored the adaptive value of satellite behaviour. While literature suggests that individuals employ satellite behaviour to get mates, its relative advantage over other non-bourgeois tactics remains unexplored. Through laboratory experiments, I showed that silent males do not gain additional mating benefits by behaving as satellites, suggesting that satellite strategy may not be the only alternative tactic employed by silent males to get mates. In the third chapter of my thesis, I investigated why baffling is not commonly observed in the field given its amplification advantage over the other two ARTs, silent and calling. Using an individual-based modelling approach, I explored whether frequency-dependent, density-dependent selection or habitat structure could limit the mating success of bafflers. The results of the study showed that the co-existence of these tactics over ecological time scales is facilitated by the spatial structure of the landscape they inhabit, which served to equalize the otherwise unequal mating benefits of the three tactics. In the last chapter of my thesis, I explore the mortality costs of the two ARTs due to predation. Through laboratory experiments using the green lynx spider as the predator, I showed that the three ARTs elicit a very low but similar likelihood of being attacked and the mortality costs related to these attacks are negligible. The findings suggest that the three ARTs are mildly vulnerable to predation by their natural predator. In summary, my thesis demonstrates that the ARTs expressed by O. henryi provide similar mating benefits. The similar mating benefits of the ARTs and negligible mortality costs due to predation may allow O. henryi males to maximise fitness in varying ecological conditions.
