Evolution

A major feature of floral display in many species is the aggregation of individual flowers into inflorescences. Inflorescences containing different numbers of flowers are likely to be differentially successful as pollen donors and receivers, and thus inflorescence size may influence the fitness of the plant on which an inflorescence is borne. We begin with the premise that inflorescence size is fundamentally an evolved trait and attempt to show or suggest some of the selection pressures and environmental limitations that may influence inflorescence size. In particular, this study centers on three sources of reproductive failure: failure of pod initiation, failure of fruit maturation, and failure to donate pollen. We emphasize intraspecific comparisons, in view of our interest in possible adaptive consequences. Our interest in the question of the evolution of inflorescence (umbel) size in Asclepias was sparked by the general observation that the number of fruits matured per inflorescence was commonly far smaller than the number of flowers in the inflorescence, and often much smaller than the number of young pods initiated (see also Woodson, 1941; Stevens, 1945; Moore, 1946, 1947; Sparrow and Pearson, 1948; Stebbins, 1951). We then asked what might be the adaptive value of producing so many flowers with such a low probability of producing seeds.

Chromosomal inversions are theorized to play an important role in adaptation by preventing recombination, but testing this hypothesis requires an understanding of the rate of inversion fixation. Here, we use chromosome-level whole-genome assemblies for 32 genera of plants to ask how fast inversions accumulate and what factors affect this rate. We find that on average species accumulate 4-25 inversions per million generations, but this rate is highly variable, and we find no correlation between sequence divergence or repeat content and the number of inversions or the proportion of genome that was inverted and only a small correlation with chromosome size. We also find that inversion regions are depleted for genes and enriched for TEs compared to the genomic background. This suggests that idiosyncratic forces, like natural selection and demography, are controlling how fast inversions fix.

Incubation behavior is one component of reproductive effort and thus influences the evolution of life-history strategies. We examined the relative importance of body mass, frequency of mate feeding, food, nest predation, and ambient temperature to explain interspecific variation in incubation behavior (nest attentiveness, on- and off-bout durations, and nest trips per hour) using comparative analyses for North American passerines in which only females incubate. Body mass and frequency of mate feeding explained little variation in incubation behavior. We were also unable to detect any influence of foot; diet and foraging strategy explained little interspecific variation in incubation behavior. However, the typical temperature encountered during reproduction explained significant variation in incubation behavior: Species breeding in colder environments take shorter bouts off the nest, which prevents eggs from cooling to temperatures below the physiological zero temperature. These species must compensate for shorter off-bouts by taking more of them (thus shorter on-bouts) to obtain needed energy for incubation. Nest predation also explains significant variation in incubation behavior among passerines: Species that endure high nest predation have evolved an incubation strategy (long on- and off-bouts) that minimizes activity that could attract predators. Nest substrate explained additional variation in incubation behavior (cavity-nesting birds have shorter on-bouts and make more frequent nest trips), presumably because nest predation and/or temperature varies among nest substrates. Thus, nest predation can influence reproductive effort in a way previously not demonstrated--by placing a constraint on parental activity at the nest. Incubating birds face an ecological cost associated with reproductive effort (predation of entire brood) that should be considered in future attempts to explain avian life-history evolution.

Confirmatory path analysis is a statistical technique to build models of causal hypotheses among variables and test if the data conform with the causal model. However, classical path analysis techniques ignore the nonindependence of observations due to phylogenetic relatedness among species, possibly leading to spurious results. Here, we present a simple method to perform phylogenetic confirmatory path analysis (PPA). We analyzed simulated datasets with varying amounts of phylogenetic signal in the data and a known underlying causal structure linking the traits to estimate Type I error and power. Results show that Type I error for PPA appeared to be slightly anticonservative (range: 0.047–0.072) but path analysis models ignoring phylogenetic signal resulted in much higher Type I error rates, which were positively related to the amount of phylogenetic signal (range: 0.051 for λ= 0 to 0.916 for λ= 1). Further, the power of the test was not compromised when accounting for phylogeny. As an example of the application of PPA, we revisit a study on the correlates of aggressive broodmate competition across seven avian families. The use of PPA allowed us to gain greater insight into the plausible causal paths linking species traits to aggressive broodmate competition.

DISENTANGLING EVOLUTIONARY CAUSE-EFFECT RELATIONSHIPS WITH PHYLOGENETIC CONFIRMATORY PATH ANALYSIS

解开进化因果关系：基于系统发育的验证性路径分析

Abstract Understanding what processes shape the formation of species’ geographic range limits is one central objective linking ecology and evolutionary biology. One potentially key process is sexual selection; yet, theory examining how sexual selection could shape eco-evolutionary dynamics in marginal populations is still lacking. In species with separate sexes, range limits could be shaped by limitations in encountering mates at low densities. Sexual selection could therefore modulate mate limitation and resulting extinction-colonisation dynamics at range margins, through evolution of mate encounter ability and/or mate competition traits, and their demographic consequences. We use a spatially explicit eco-genetic model to reveal how different forms of sexual selection can variably affect emerging range limits. Larger ranges emerged when sexual selection acted exclusively on traits increasing mate encounter probability, thus reducing female’s mate limitation towards the range margins. In contrast, sexual selection via mate competition narrowed range limits due to increased trait-dependent mortality in males and elevated mate limitation for females. When mate encounter coevolved with mate competition, their combined effects on range limits depended on the mating system (polygyny versus monogamy). Our results demonstrate that evolution of species’ ranges may be importantly shaped by feedbacks between sexual selection and spatial population demography and dynamics.

Abstract Females that mate multiply make postmating choices about which sperm fertilize their eggs (cryptic female choice); however, the male characteristics they use to make such choices remain unclear. In this study, we sought to understand female sperm use patterns by evaluating whether Drosophila melanogaster females adjust sperm use (second male paternity) in response to four main factors: male genotype, male courtship effort, male pheromone alteration, and male postmating reproductive morphology. Our experiment was replicated across four different D. melanogaster lines, in a full factorial design, including a pheromone manipulation in which second males were perfumed to resemble heterospecific (D. yakuba) males. We found that females prefer longer sperm—regardless of mating order—in almost all contexts; this observed pattern of ‘long-sperm precedence’ is consistent with female postmating choice of high-fitness male traits. Nonetheless, we also found that this general preference can be plastically altered by females in response to effects including perfuming treatment; this differential female sperm use is between otherwise identical males, and therefore solely female-mediated. Furthermore, our finding that females exercise choice using diverse criteria suggests a possible mechanism for the maintenance of variation in sexually selected male traits.

Abstract In the more than 50 years since the initial conceptualization of the suture zone, little work has been done to take full advantage of the comparative capability of these geographic regions. During this time, great advances have been made in hybrid zone research that have provided invaluable insight in speciation and evolution. Hybrid zones have long been recognized to be “windows to the evolutionary process”. If a single hybrid zone provides a window, then multiple hybrid zones in a suture zone can provide a panoramic view of the evolutionary process. Here, we hope to redirect attention to suture zones and bring the advances from hybrid zone research to a comparative framework and further expand our understanding of speciation and evolution. In this review, we recount the historical discussions surrounding suture zones, briefly review what we can learn from hybrid zones, and review the comparative studies done on suture zones thus far. We also highlight the opportunities and challenges of performing research in suture zones to help guide researchers hoping to start a research project in these regions. Lastly, we propose future directions and questions for comparative research that can be done in suture zones.

Abstract Telomeres are DNA-protein structures that primarily protect chromosomes and serve multiple functions of gene regulation. When cells divide, telomeres shorten and their main repair system in ectotherms - telomerase – replaces lost nucleotide complexes ((T2AG3)n in vertebrates). It remains a challenge to experimentally investigate resource requirements for telomere maintenance and its effects on lifespan-reproductive tradeoffs in the wild. In sand lizards (Lacerta agilis), we show that higher female investments into reproduction results in corresponding shortening of telomeres and that males have less frequent and less profound telomere shortening than females; a contributing factor to this may be males’ higher telomerase levels. To manipulate resource access for telomere maintenance, we exploit a pseudo-experimental opportunity to analyze ‘onboard’ resources long-term using lizards that drop their tails with fat and nutrient deposits when attacked by predators. Females with less resources due to regrown tails less often and less profoundly elongate telomeres. Adult lizards with the most TL elongation live the longest, females with the highest lifetime reproductive success shorten telomeres the most, whereas males with the most telomere elongation have the highest lifetime reproductive success. This suggests ongoing evolution of resource-constrained telomere maintenance.

Abstract Hybrid zones provide valuable opportunities to interrogate the processes that drive speciation. In a new study, Hardy et al. (2024) demonstrate that the dominant vegetation type in patchy cordgrass salt marshes and mangrove swamps drives a mosaic hybrid zone between two species of killifish. Further, the authors showed that hybridization is asymmetrical, and that Fundulus grandis is more likely to hybridize than F. heteroclitus. This study highlights the need for interdisciplinary study of the environmental context of reproductive isolation
