Ungulate spatiotemporal responses to contrasting predation risk from wolves and snow leopards

Spatial responses to risk from multiple predators can precipitate emergent consequences for prey (i.e., multiple-predator effects, MPEs) and mediate indirect interactions between predators. How prey navigate risk from multiple predators may therefore have important ramifications for understanding the propagation of predation-risk effects (PREs) through ecosystems. The interaction of predator and prey traits has emerged as a potentially key driver of anti-predator behaviour but remains underexplored in large vertebrate systems, particularly where sympatric prey share multiple predators. We sought to better generalize our understanding of how predators influence their ecosystems by considering how multiple sources of contingency drive prey distribution in a multi-predator-multi-prey system. Specifically, we explored how two sympatric ungulates with different escape tactics – vertically agile, scrambling ibex (Capra sibirica) and sprinting argali (Ovis ammon) – responded to predation risk from shared predators with contrasting hunting modes – cursorial wolves (Canis lupus) and vertical-ambushing, stalking snow leopards (Panthera uncia). Contrasting risk posed by the two predators presented prey with clear trade-offs. Ibex selected for greater exposure to chronic long-term risk from snow leopards, and argali for wolves, in a nearly symmetrical manner that was predictable based on the compatibility of their respective traits. Yet, acute short-term risk from the same predator upended these long-term strategies, increasing each ungulate's exposure to risk from the alternate predator in a manner consistent with a scenario in which conflicting anti-predator behaviours precipitate risk-enhancing MPEs and mediate predator facilitation. By contrast, reactive responses to wolves led ibex to reduce their exposure to risk from both predators – a risk-reducing MPE. Evidence of a similar reactive risk-reducing effect for argali vis-à-vis snow leopards was lacking. Our results suggest that prey spatial responses and any resulting MPEs and prey-mediated interactions between predators are contingent on the interplay of hunting mode and escape tactics. Further investigation of interactions among various drivers of contingency in PREs will contribute to a more comprehensive understanding and improved forecasting of the ecological effects of predators.

Disentangling the causes of age-assortative mating in bird populations with contrasting life-history strategies

<ol> <li>Age shapes fundamental processes related to behaviour, survival and reproduction. Where age influences reproductive success, non-random mating with respect to age can magnify or mitigate such effects. Consequently, the correlation in partners' age across a population may influence its productivity. Despite widespread evidence for age-assortative mating, little is known about what drives this assortment and its variation. Specifically, the relative importance of active (same-age mate preference) and passive processes (assortment as a consequence of other spatial or temporal effects) in driving age-assortment is not well understood.</li> <li>In this paper, we compare breeding data from a great tit and mute swan population (51- and 31-year datasets respectively) to tease apart the contributions of pair retention, cohort age-structure, and active age-related mate selection to age-assortment in species with contrasting life-histories.</li> <li>Both species show age-assortative mating, and variable assortment between years. However, we demonstrate that the drivers of age-assortment differ between the species, as expected from their life-histories and resultant demographic differences. In great tits, pair fidelity has a weak effect on age-assortative mating through pair retention; variation in age-assortment is primarily driven by fluctuations in age-structure from variable juvenile recruitment. Age-assortative mating is therefore largely passive, with no evidence consistent with active age-related mate selection. In mute swans, age-assortment is partly explained by pair retention, but not population age-structure, and evidence exists for active age-assortative pairing.</li> <li>This difference is likely to result from shorter life-spans in great tits compared to mute swans, leading to fundamental differences in their population age-structure, whereby a larger proportion of great tit populations consist of a single age-cohort. In mute swans, age-assortative pairing through mate selection may also be driven by greater age-dependent variation in fitness.</li> <li>The study highlights the importance of considering how different life-histories, and demographic differences arising from these, affect population processes that appear congruent across species. We suggest that future research should focus on uncovering the proximate mechanisms that lead to variation in active age-assortative mate selection (as seen in mute swans); and the consequences of variation in age-structure on the ecological and social functioning of wild populations.</li> </ol>

Contrasting effects of two phenotypes of an alpine cushion plant on understory species drive community assembly

In alpine systems, cushion plants act as foundation species by ameliorating local environmental conditions. Empirical studies indicate that contrasting phenotypes of alpine cushion species have different effects on understory plant species, either facilitative or competitive. Furthermore, dependent species within each community type might also exhibit different responses to each cushion phenotype, which can be clustered into several "response groups". Additionally, these species-groups specific responses to alpine cushion species phenotypes could alter community assembly. However, very few studies have assessed responses of dependent communities at species-group levels, in particular for both above- and below-ground communities. Here, we selected a loose and a tight phenotype of the alpine cushion species Thylacospermum caespitosum in two sites in northwest China, and use the relative intensity of interactions index to quantify cushion plant effects on subordinate communities of plants and soil fungi and bacteria. We assessed variations in responses of both above- and below-ground organisms to cushion plant effects at species-group level. Species-group level analyses showed that the effects of the phenotype varied among groups of each of the three community types, and different species-groups were composed of unique taxa. Additionally, we found that loose cushions enhanced stochastic processes in community assembly, for plants and soil fungi but not for soil bacteria. These variations of phenotypic effects on different species-group induced contrasting taxonomic composition between groups and altered community assembly thereby. Our study highlights the occurrence of contrasting effects of two phenotypes of a foundation cushion plant on understory plants, soil fungi and bacteria community composition, but not necessarily on their richness. We also showed that assessing responses of understory species at the species-group level allows a more realistic and mechanistic understanding of biotic interactions both for above- and below-ground communities.

Contrasting phylogeographic patterns of mitochondrial and genome-wide variation in the groundwater amphipod (Crangonyx islandicus) that survived the Ice age in Iceland

In this zip "DataAvailability.zip" all the data and parameter files, as well as R scripts and bash codes used to perform the analyses of the mitochondrial and the RADseq data are provided. A ReadMe file is available at the root describing the content of the different folders and files. Below is the abstract of the associated manuscript: Analysis of phylogeographic patterns have often been based on mitochondrial DNA variation, but recent analyses dealing with nuclear DNA have in some instances revealed mito-nuclear discordances and complex evolutionary histories. These enigmatic scenarios which may involve stochastic lineage sorting, ancestral hybridization, past dispersal, and secondary contacts are increasingly scrutinized with a new generation of genomic tools such as RADseq, which pose also additional analytical challenges. Here, we revisited the previously inconclusive phylogeographic history, showing mito-nuclear discordance, of an endemic groundwater amphipod from Iceland, Crangonyx islandicus, which is the only metazoan known to have survived the Pleistocene beneath the glaciers. Previous studies based on three DNA markers documented a mitochondrial scenario with the main divergence occurring between populations in northern Iceland and an ITS scenario with the main divergence between the south and north. We used double digest restriction-site-associated DNA sequencing (ddRADseq) to clarify this mito-nuclear discordance by applying several statistical methods while estimating the sensitivity to different analytical approaches (data-type, differentiation indices and base call uncertainty). A majority of nuclear markers and methods support the ITS divergence. Nevertheless, a more complex scenario emerges, possibly involving introgression led by male-biased dispersal among northern locations or mitochondrial capture which may have been further strengthened by natural selection.

Adaptation to distinct habitats is maintained by contrasting selection at different life stages in sunflower ecotypes

Conspecific populations living in adjacent but contrasting microenvironments represent excellent systems for studying natural selection. These systems are valuable because gene flow is expected to force genetic homogeneity except at loci experiencing divergent selection. A history of reciprocal transplant and common garden studies in such systems, and a growing number of genomic studies, have contributed to understanding how selection operates in natural populations. While selection can vary across different fitness components and life stages, few studies have investigated how this ultimately affects allele frequencies and the maintenance of divergence between populations. Here, we study two sunflower ecotypes in distinct, adjacent habitats by combining demographic models with genome-wide sequence data to estimate fitness and allele frequency change at multiple life stages. This framework allows us to estimate that only local ecotypes are likely to experience positive population growth (λ>1) and that the maintenance of divergent adaptation appears to be mediated via habitat- and life-stage-specific selection. We identify genetic variation, significantly driven by loci in chromosomal inversions, associated with different life history strategies in neighbouring ecotypes that optimize different fitness components and may contribute to the maintenance of distinct ecotypes.
