These are papers that I believe have contributed the most influential insights.
Reichard, M. - Le Comber, S.C. - Smith, C. (2007) Sneaking from a female perspective. Animal Behaviour, 74, 679-688.
We oppose the standard view that mating by non-territorial males represents coercion by low-quality males. Instead, we review empirical evidence to formally propose that in many cases females prefer to mate with non-territorial males, overcoming constraints to the expression of their partner preferences by dominant males monopolizing resources.
Reichard, M. - Smith, C. - Jordan, W.C. (2004) Genetic evidence reveals density-dependent mediated success of alternative mating behaviours in the European bitterling (Rhodeus sericeus). Molecular Ecology, 13, 1569-1578.
Combining behavioural and genetic data from large-scale experiments, we provided the first demonstration that territorial male reproductive success (number of offspring sired) is strongly density-dependent; it dramatically declined with increasing male population density, being equal to the reproductive success of sneaker males at the highest male density. Consequently, territoriality broke down at the highest male densities, with important population consequences.
Agbali, M. - Reichard, M. - Bryjová, A. - Bryja, J. - Smith, C. (2010) Mate choice for non-additive genetic benefits correlate with MHC dissimilarity in the rose bitterling (Rhodeus ocellatus). Evolution, 64, 1683-1696.
This double-blind study experimentally confirmed a positive link between partner choice, partner compatibility and offspring survival, and linked these effects to MHC dissimilarity. Females preferred MHC-dissimilar males, which doubled embryo survival in in vitro fertilization trials. The outcome was later confirmed by further experimental tests.
Reichard, M. - Vrtílek, M. - Douda, K. - Smith, C. (2012) An invasive species reverses the roles in a host-parasite relationship between bitterling fish and unionid mussels. Biology Letters, 8, 601-604.
We illustrated how intricate the effects of invasive species may be by showing that an invading mussel caused complete ecological reversal by turning a host into a parasite and vice versa. The study also documented how an invasive species may temporarily benefit from a coevolutionary lag by exploiting evolutionarily naive hosts.
Reichard, M. - Smith, C. - Bryja, J. (2008) Seasonal change in the opportunity for sexual selection. Molecular Ecology, 17, 642-651.
We showed that large dominant males had a lower opportunity to monopolize all females at the start of the mating season, when many females were receptive simultaneously. However, in the latter part of breeding season, as females become receptive asynchronously, large territorial males were able to monopolize most matings.
Reichard, M. - Polačik - M., Tarkan, A.S. - Spence, R. - Gaygusuz, O. - Ercan, E. - Ondračková, M. - Smith, C. (2010) The bitterling mussel coevolutionary relationship in areas of recent and ancient sympatry. Evolution, 64, 3047-3056.
This study has shown that parasite populations with a recent coevolutionary history with the host (bitterling and mussels in Central Europe) suffer lower host resistance than populations with an ancient coevolutionary history with the host (in Turkey).
