“…Mating success in the sand goby (Pomatoschistus minutus) was more evenly distributed and less skewed towards large males under turbid conditions compared with clear water [25]. The difference in mean length between mated and unmated males was also smaller in turbid water [25]. Also in the Baltic Sea, turbidity impeded mate choice in the broadnosed pipefish (Syngnathus typhle) [26].…”

One contribution of 18 to a theme issue 'Human influences on evolution, and the ecological and societal consequences'. Eutrophication increases primary production and changes the relative abundance, taxonomic composition and spatial distribution of primary producers within an aquatic ecosystem. The changes in composition and location of resources alter the distribution and flow of energy and biomass throughout the food web. Changes in productivity also alter the physico-chemical environment, which has further effects on the biota. Such ecological changes influence the direction and strength of natural and sexual selection experienced by populations. Besides altering selection, they can also erode the habitat gradients and/or behavioural mechanisms that maintain ecological separation and reproductive isolation among species. Consequently, eutrophication of lakes commonly results in reduced ecological specialization as well as genetic and phenotypic homogenization among lakes and among niches within lakes. We argue that the associated loss in functional diversity and niche differentiation may lead to decreased carrying capacity and lower resource-use efficiency by consumers. We show that in central European whitefish species radiations, the functional diversity affected by eutrophication-induced speciation reversal correlates with community-wide trophic transfer efficiency (fisheries yield per unit phosphorus). We take this as an example of how evolutionary dynamics driven by anthropogenic environmental change can have lasting effects on biodiversity and ecosystem functioning.This article is part of the themed issue 'Human influences on evolution, and the ecological and societal consequences'.

“…The study of Bonenfant et al (2003) is one of many that highlight that the population structure and the strength of sexual selection can be modified by environmental factors, such as variations in visibility (Seehausen et al 1997;Seehausen & van Alphen 1998;Järvenpää & Lindströ m 2004) or the availability of nest sites or other necessary resources for reproduction (Simmons 1992;Forsgren et al 1996;Borg et al 2002;Debuse et al 2003). Low-visibility scenarios mimic low population density if individuals detect each other visually.…”

Two very basic ideas in sexual selection are heavily influenced by numbers of potential mates: the evolution of anisogamy, leading to sex role differentiation, and the frequency dependence of reproductive success that tends to equalize primary sex ratios. However, being explicit about the numbers of potential mates is not typical to most evolutionary theory of sexual selection. Here, we argue that this may prevent us from finding the appropriate ecological equilibria that determine the evolutionary endpoints of selection. We review both theoretical and empirical advances on how population density may influence aspects of mating systems such as intrasexual competition, female choice or resistance, and parental care. Density can have strong effects on selective pressures, whether or not there is phenotypic plasticity in individual strategies with respect to density. Mating skew may either increase or decrease with density, which may be aided or counteracted by changes in female behaviour. Switchpoints between alternative mating strategies can be density dependent, and mate encounter rates may influence mate choice (including mutual mate choice), multiple mating, female resistance to male mating attempts, mate searching, mate guarding, parental care, and the probability of divorce. Considering density-dependent selection may be essential for understanding how populations can persist at all despite sexual conflict, but simple models seem to fail to predict the diversity of observed responses in nature. This highlights the importance of considering the interaction between mating systems and population dynamics, and we strongly encourage further work in this area.

“…Gasterosteus aculeatus: Rick et al 2006), water turbidity (e.g. Pomatoschistus minutus : Jarvenpaa & Lindstrom 2004) and temperature, can be effective agents in the modulation of mating behaviour. In sand gobies, P. minutus, a trend towards a higher frequency of femaleefemale interactions was observed in the cold water treatment, suggesting that females were more liable to compete when the water was cold.…”

The effect of temperature on mate preferences and female–female interactions in Syngnathus abaster

et al. 2007

Despite much effort to ascertain the consequences of temperature variation for a wide range of animal performance traits, the effect of temperature on interactions among organisms is still poorly understood. The present work tests for a direct influence of water temperature on sexual recognition, mate preferences and femaleefemale interactions in the pipefish, Syngnathus abaster. Three experiments were conducted by monitoring time spent in the vicinity of conspecifics at three water temperatures intended to reflect sea water temperatures before the onset of reproduction (15 C) and during the early (18 C) and late breeding season (24 C). Four major results emerged: (1) S. abaster can visually discriminate potential mates from fish of the same sex; (2) males and females responded differently with the former diverting their attention towards the opposite sex at intermediate (18 C) and high temperatures (24 C), while the latter only showed a significant interest in potential mates at 24 C, devoting an equal amount of interest towards both males and females at 18 C; (3) at breeding season water temperatures, both sexes discriminated against smaller partners, preferring larger ones; (4) different-sized females adopted distinct temperature-modulated behavioural responses, possibly because large dominant females, which engage in competition at 18 C, constrained the reproduction of smaller ones, which seem to compete only at 24 C. These results highlight the importance of temperature as an effective agent in the modulation of S. abaster reproductive behaviour. Considerations on the ecological significance of the observed behavioural patterns are also discussed.
