Data from: The ecological stage changes benefits of mate choice and drives preference divergence
<p>Preference divergence is thought to contribute to reproductive isolation. Ecology can alter the way selection acts on female preferences, making them most likely to diverge when ecological conditions vary among populations. We present a novel mechanism for ecologically dependent sexual selection, termed 'the ecological stage' to highlight its ecological dependence. Our hypothesized mechanism emphasizes that males and females interact over mating in a specific ecological context, and different ecological conditions change the costs and benefits of mating interactions, selecting for different preferences in distinct environments and different male traits, especially when traits are condition dependent. We test key predictions of this mechanism in a sympatric threespine stickleback species pair. We used a maternal half-sib split-clutch design for both species, mating females to attractive and unattractive males, and raising progeny on alternate diets that mimic the specialized diets of the species in nature. We estimated the benefits of mate choice for an indicator trait (male nuptial color) by measuring many fitness components across the lifetimes of both sons and daughters from these crosses. We analyzed fitness data using a combination of aster and mixed models. We found that many benefits of mating with high color males depended on both species and diet. These results support the ecological stage hypothesis for stickleback. Finally, we discuss the potential role of this mechanism for other taxa and highlight its ability to enhance reproductive isolation as speciation proceeds, thus facilitating the evolution of strong reproductive isolation.</p>
Data from: Testing the role of mating preference in a case of incomplete ecological speciation with gene flow
Mating preference can evolve as a side effect of ecological adaptation and simultaneously contribute to speciation in certain scenarios. However, theoretical predictions have been difficult to test experimentally because there has not been any simple way to relate empirical and theoretical parameters. Recently, it has been shown that the r coefficient and other statistics can be used to estimate mating preference in wild-captured mating pairs. In the present work we use these estimators to test whether mating preference has significantly increased in a context favorable for ecological divergence. We perform the study using two groups of samples from populations of the marine gastropod Littorina saxatilis: 1) a group of bimodal populations affected by ecological divergence, and 2) a group of unimodal populations. The results show that mating preference (unlike the trait affected by the preference) does not increase when two ecotypes meet and mate in sympatry, which suggests that mating preference must be controlled by strong stabilizing natural selection, and/or limited by mating cost. This would suggest that mating preference would rarely contribute to speciation under the face of gene flow in these ecotypes.
Data from: Ecological opportunity and the evolution of habitat preferences in an arid-zone bird: implications for speciation in a climate-modified landscape
Bioclimatic models are widely used to investigate the impacts of climate change on species distributions. Range shifts are expected to occur as species track their current climate niche yet the potential for exploitation of new ecological opportunities that may arise as ecosystems and communities remodel is rarely considered. Here we show that grasswrens of the Amytornis textilis-modestus complex responded to new ecological opportunities in Australia's arid biome through shifts in habitat preference following the development of chenopod shrublands during the late Plio-Pleistocene. We find evidence of spatially explicit responses to climatically driven landscape changes including changes in niche width and patterns of population growth. Conservation of structural and functional aspects of the ancestral niche appear to have facilitated recent habitat shifts, while demographic responses to late Pleistocene climate change provide evidence for the greater resilience of populations inhabiting the recently evolved chenopod shrubland communities. Similar responses could occur under future climate change in species exposed to novel ecological conditions, or those already occupying spatially heterogeneous landscapes. Mechanistic models that consider structural and functional aspects of the niche along with regional hydro-dynamics may be better predictors of future climate responses in Australia's arid biome than bioclimatic models alone.
Female preference and adverse developmental effects of glyphosate-based herbicides on ecologically relevant traits in Japanese quail
<p>Controversial glyphosate-based herbicides (GBHs) are the most frequently used herbicides globally. An increasing number of studies have identified GBH residues in soil, water and even human food that may expose non-target organism including wildlife, livestock, and humans to health risks. After a heated debate, European Union allowed the use of GBHs to continue until 2022, after which their risks will be re-evaluated. Thus, decision makers urgently need scientific evidence on GBH residues and their possible effects on ecosystems. An important, yet neglected, aspect is to assess whether animals show preference or avoidance for GBH contaminated food, as it can influence the likelihood of adverse health effects in wildlife. Here, using Japanese quails (<i>Coturnix japonica</i>) as our model, we show that females preferred GBH-contaminated food compared to control food. In females, exposure to GBHs caused delayed plumage development, and GBH residues were present in eggs, muscles and liver. These results indicate that female preference is not adaptive, potentially exposing non-target animals to greater risk of adverse effects of GBHs in natural and agricultural environments. Our results on tissue residues suggest that further studies are needed to understand the risks of such residues in the food chain.</p>
The ecological stage maintains preference differentiation and promotes speciation
<p>Influential models of speciation by sexual selection posit either a single shared preference for a universal display, expressed only when males are locally adapted and hence in high condition, or that shared loci evolve population-specific alleles for displays and preferences. However, many closely related species instead show substantial differences across categorically different traits. We present a model of secondary contact whereby females maintain preferences for distinct displays that indicate both male condition and their match to distinct environments, fostering reproductive isolation among diverging species. This occurs even with search costs and with independent preference loci targeting independent displays. Such preferences can also evolve from standing variation. Divergence occurs because condition-dependent display and female preference depend on local ecology, and females obtain different benefits of choice. Given the ubiquity of ecological differences among environments, our model could help explain the evolution of striking radiations of displays seen in nature.</p>
