Female reproductive fluid increases the opportunities for post-mating sexual selection by prolonging egg fertilization window

Female reproductive fluid, the fluid that surrounds the eggs, has attracted increasing attention for its role in fertilization and post-mating sexual selection through its effects on sperm traits. Surprisingly, however, only a few studies have investigated the effects of female reproductive fluid on the eggs. Yet, these effects might offer great potential to affect fertilization dynamics by, for example, increasing the opportunities for post-mating sexual selection. Here, we determined whether, by extending the egg fertilization window (time available for egg fertilization), the female reproductive fluid could also increase the opportunities for multiple paternity. Using the Zebrafish Danio rerio we first tested the prediction that female reproductive fluid increases the egg fertilization window, and then, using a split-brood design with sperm of two males added at different times after eggs activation, we tested whether the degree of multiple paternity varies in presence or absence of female reproductive fluid. Our results reveal the potential of the female reproductive fluid to increase multiple paternity throughout its effects on the egg fertilization window thus broadening our knowledge of the mechanisms females in externally fertilizing species affect post-mating sexual selection.

Visual complexity of egg patterns predicts egg rejection according to Weber's law

Visual complexity is ubiquitous in nature. Drivers of complexity include selection in coevolutionary arms races between antagonists. However, the causes and consequences of biological complexity and its perception are largely understudied, partly because complexity is difficult to quantify. Here, we address this by studying egg pattern complexity and its perception in hosts (tawny-flanked prinia Prinia subflava ), which visually recognize and reject mimetic eggs of their virulent brood parasite (cuckoo finch Anomalospiza imberbis ). Using field data and an optimization algorithm, we compute a complexity metric which predicts rejection of experimentally placed conspecific eggs in prinia nests. Real cuckoo finch eggs exhibit significantly lower pattern complexity than prinia eggs, suggesting that high complexity benefits hosts because it distinguishes host eggs from parasitic eggs. We show that prinias perceive complexity differences according to Weber's law of proportional processing (i.e. relative, rather than absolute, differences between stimuli are processed in discrimination, such that two eggs with simple patterns are more easily discriminable than two with complex patterns). This may influence coevolutionary trajectories of hosts and parasites. The new methods presented for quantifying complexity and its perception can help us to understand selection pressures driving the evolution of complexity and its consequences for species interactions.

Long-term observation of the egg and chick size in the nests of Larus ichthyaetus in Lake Chany,West Siberia, Russia

Data on long-term observation and morphological study of the eggs of the great black-headed gull Larus ichthyaetus in the nesting colonies of gulls on islands of Lake Chany. Russia. Data on long-term observation and morphological study of the eggs (Data S1) and chick (Data S2) of the great black-headed gull Larus ichthyaetus in the nesting colonies of gulls on islands of Lake Chany, Russia   Abstract  This data set describes the long-term observation and morphological study of the eggs of the great black-headed gull Larus ichthyaetus in the gull nesting colonies on the islands of Lake Chany. Lake Chany is located in the Baraba forest-steppe of the West Siberian Plain, Russia, between the Ob and Irtish rivers. Lake Chany is protected by the Ramsar Convention on the Wetlands of International Importance, indicating that the lake is an important site for migratory birds, including L. ichthyaetus. This dataset contains the size and fate of all eggs, as well as the size of hatched chicks in 1164 observed L. ichthyaetus nests from 1993 to 2003.

Unpublished data on predation on leaf beetle eggs in willow bushes

The data were collected during field experiments in 2012 and 2014 in the Uppsala area, Sweden. I neither found the time nor research funding to use the data in a scientific publication or otherwise. In both field seasons the predation on leaf beetle eggs on willow bushes/plants was measured. Additionally, in 2012 the insect diversity on the bushes was sampled.
