The gut microbiome reflects ancestry despite dietary shifts across a hybrid zone

The microbiome is critical to an organism's phenotype, and its composition is shaped by, and a driver of, eco-evolutionary interactions. We investigated how host ancestry, habitat, and diet shape gut microbial composition in a mammalian hybrid zone that occurs across an ecotone between distinct vegetation communities. We found that habitat is the primary determinant of diet, while host genotype is the primary determinant of the gut microbiome—a finding further supported by intermediate microbiome composition in first generation hybrids. Despite these distinct primary drivers, microbial richness was correlated with diet richness, and individuals that maintained higher dietary richness had greater gut microbial community stability. Both relationships were stronger in the relative dietary generalist of the two parental species. Our findings show that host ancestry interacts with dietary habits to shape the microbiome, ultimately resulting in the organismal phenotypic plasticity that host-microbial interactions allow.

Limited movement of an avian hybrid zone in relation to regional variation in magnitude of climate change

Studies of natural hybrid zones can provide documentation of range shifts in response to climate change and identify loci important to reproductive isolation. Using a temporal (36–38 years) comparison of the black-capped (Poecile atricapillus) and Carolina (P. carolinensis) chickadee hybrid zone, we investigated movement of the western portion of the zone (western Missouri) and assessed whether loci and pathways underpinning reproductive isolation were similar to those in the eastern portion of the hybrid zone. Using 92 birds sampled along the hybrid zone transect in 2016 and 68 birds sampled between 1978 and 1980, we generated 11,669 SNPs via ddRADseq. These SNPs were used to assess movement of the hybrid zone through time and to evaluate variation in introgression among loci. We demonstrate that the interface has moved ~5 km to the northwest over the last 36–38 years, i.e., at only one-fifth the rate at which the eastern portion (e.g., Pennsylvania, Ohio) of the hybrid zone has moved. Temperature trends over the last 38 years reveal that eastern areas have warmed 50% more than western areas in terms of annual mean temperature, possibly providing an explanation for the slower movement of the hybrid zone in Missouri. Our results suggest hybrid zone movement in broadly distributed species, such as chickadees, will vary between areas in response to local differences in the impacts of climate change.

Data From: Females alter their mate preferences depending on hybridization risk

Mating with another species is often maladaptive because it generally results in no or low-fitness offspring. When hybridization is sufficiently costly, individuals should avoid mating with heterospecifics even if it reduces their ability to mate with high-quality conspecifics that resemble heterospecifics. Here, we used spadefoot toads, Spea multiplicata, to evaluate whether females alter their preferences for conspecific male sexual signals (call rate) depending on heterospecific presence. When presented with conspecific signals against a background including both conspecific and heterospecific signals, females preferred male traits that were most dissimilar to heterospecifics—even though these signals are potentially associated with lower-quality mates. However, when these same females were presented with a background that included only conspecific signals, some females switched their preferences, choosing conspecific signals that were exaggerated and indicative of high-quality conspecific mates. Because only some females switched their preferences between these two chorus treatments, there was no population-level preference for exaggerated male signals in the absence of heterospecifics. Thus, hybridization risk can impact mate choice and thereby alter patterns of sexual selection. These results also emphasize that reproductive barriers between species (such as mate choice) can be context-dependent, with important implications for the origins and maintenance of species boundaries.

Figure 1: Venn diagram of a DSm hybrid model for a 3D frame.

As another simple example of hybrid DSm model, let's consider the 3D case with the frame £ = fµ1; µ2; µ3g with the model M 6= Mf in which we force all possible conjunctions to be empty, but µ1 \ µ2. This hybrid DSm model is then represented with the Venn diagram on Fig. 1 (where boundaries of intersection of µ1 and µ2 are not precisely de¯ned if µ1 and µ2 represent only fuzzy concepts like smallness and tallness by example).

Museum genomics reveals the hybrid origin of an extinct crater lake endemic

Crater lake fishes are common evolutionary model systems, with recent studies suggesting a key role for gene flow in promoting rapid adaptation and speciation. However, the study of these young lakes can be complicated by human-mediated extinctions. Museum genomics approaches integrating genetic data from recently extinct species are therefore critical to understanding the complex evolutionary histories of these fragile systems. Here, we examine the evolutionary history of an extinct Southern Hemisphere crater lake endemic, the rainbowfish Melanotaenia eachamensis. We undertook comprehensive sampling of extant rainbowfish populations of the Atherton Tablelands of Australia alongside historical museum material to understand the evolutionary origins of the extinct crater lake population and the dynamics of gene flow across the ecoregion. The extinct crater lake species is genetically distinct from all other nearby populations due to historic introgression between two proximate riverine lineages, similar to other prominent crater lake speciation systems, but this historic gene flow has not been sufficient to induce a species flock. Our results suggest that museum genomics approaches can be successfully combined with extant sampling to unravel complex speciation dynamics involving recently extinct species.

Maintenance of a narrow hybrid zone between native and introduced red foxes (Vulpes vulpes) despite conspecificity and high dispersal capabilities

Human-facilitated introductions of nonnative populations can lead to secondary contact between previously allopatric lineages, resulting in either homogenization of the lineages or stable hybrid zones that are maintained by pre-zygotic (e.g., behavioral) or post-zygotic (e.g., reduced hybrid fitness) reproductive barriers. We investigated patterns of gene flow between the native Sacramento Valley red fox (Vulpes vulpes patwin) and an introduced conspecific population of captive-bred (fur-farm) origin in California's Central Valley. Considering their recent divergence (i.e., ~50 kya), we hypothesized that pre-zygotic mechanisms primarily impede gene flow, rather than post-zygotic barriers. Additionally, some genes originating in nonnative foxes may confer higher fitness in the currently human-dominated landscape resulting in selective introgression into the native population. Genetic analysis of 682 red foxes (255 native, 427 nonnative) at both mitochondrial (cytB + Dloop) and nuclear loci (~19,000 SNPs) revealed significantly narrower cline widths than expected under a simulated model of unrestricted gene flow, consistent with the existence of pre- or post-zygotic reproductive barriers. We identified several loci with reduced introgression linked to behavioral divergence in captive bred foxes, which supports pre-zygotic mechanisms as a putative driver of the narrow hybrid zone. Additionally, several loci with elevated gene flow from the nonnative into the native population, were near genes associated with adaptation to human dominated landscapes. Overall, this study contributes to our understanding of hybrid zone dynamics in vertebrates, particularly in the context of species introductions and landscape changes, underscoring the importance of considering multiple mechanisms that may be at play in maintaining lineages at both the species and subspecies level.

Density functional theory calculations of 1D hybrid nanoobjects composed of alternating polycyclic hydrocarbon regions and double carbon chains

It has been proposed recently based on molecular dynamics simulations that electron irradiation of graphene nanoribbons of alternating width can lead to creation of 1D hybrid nanoobjects composed of alternating double carbon chains and polycyclic hydrocarbon regions [1]. We have performed density functional theory calculations of such 1D hybrid nanoobjects using Quantum ESPRESSO [2]. Semi-local exchange and correlation functional of Perdew, Burke and Ernzerhof [3]  and screened exchange hybrid density functional of Heyd, Scuseria and Ernzerhof [4] were used. The dependences of structure, magnetic and electronic properies on the length of chains and type of the polycyclic hydrocarbon region were studied.
