Bony fishes are the principal group of backboned animals in contemporary aquatic settings. Extant species are the focus of a vigorous program of macroevolutionary research, but paleontology offers important perspectives. Multiple fossil records bear on the evolution of bony fishes, each with its own strengths and weaknesses. Understanding of the interrelationships among living bony fishes has improved substantially in recent years, but confidence in the phylogenetic placement of fossils is highly variable. This reflects limitations in current understanding of both fossil anatomy and hard-tissue characters for extant clades. Patterns of taxonomic and morphological diversity over bony fish history remain incompletely known, with most studies restricted to particular clades or specific intervals of time. The wealth of anatomical data recorded by the fossil record could make an important addition to a growing body of work examining phenotypic evolution across living species, but incorporating this information requires the placement of fossils within phylogenetic trees. Expected final online publication date for the Annual Review of Ecology, Evolution, and Systematics, Volume 53 is November 2022.

The finding that adaptive evolution can often be substantial enough to alter ecological dynamics challenges traditional views of community ecology that ignore evolution. Here, we propose that evolution might commonly alter both local and regional processes of community assembly. We show how adaptation can substantially affect community assembly and that these effects depend on regional (metacommunity) factors, including environmental heterogeneity and its spatial structure. In particular, early colonists can often arrive from a nearby community, adapt to local conditions, and subsequently alter the establishment or abundance of late-arriving species, often producing an evolutionary priority effect. We also discuss how interaction type and relative rates of colonization, evolution, and community interactions determine divergent community outcomes. We describe new conceptual approaches that provide insights into these dynamics and statistical methods that can better evaluate their importance. Overall, we demonstrate that accounting for adaptation during community assembly opens up novel ways for making progress on fundamental questions in community ecology.

The interactions between ants and certain sap-feeding insects in the order Hemiptera are classic examples of food-for-protection mutualisms. In these associations, herbivorous hemipterans use a highly specialized, straw-like mouthpart to consume sap directly from plant phloem and xylem and, as a result, excrete a sugar-rich waste product called honeydew. Ant foragers in turn use specialized adaptations to collect and share honeydew with nestmates and, in exchange, protect hemipterans against predators. The two key innovations underlying this interaction—hemipteran sap feeding and ant harvesting of honeydew—have driven the evolutionary success and ecological dominance of ants. These interactions also carry unique costs and benefits for each partner and are highly context dependent. Understanding the factors mediating this mutualism is critical, as these interactions have broader ecological consequences for the natural and agricultural ecosystems in which they are embedded.

Myriad branches in the tree of life are intertwined through ecological relationships. Biologists have long hypothesized that intimate symbioses between lineages can influence diversification patterns to the extent that it leaves a topological imprint on the phylogenetic trees of interacting clades. Over the past few decades, cophylogenetic methods development has provided a toolkit for identifying such histories of codiversification, yet it is often difficult to determine which tools best suit the task at hand. In this review, we organize currently available cophylogenetic methods into three categories—pattern-based statistics, event-scoring methods, and more recently developed generative model–based methods—and discuss their assumptions and appropriateness for different types of cophylogenetic questions. We classify cophylogenetic systems based on their biological properties to provide a framework for empiricists investigating the macroevolution of symbioses. In addition, we provide recommendations for the next generation of cophylogenetic models that we hope will facilitate further methods development.

Fire has been an ecosystem process since plants colonized land over 400 million years ago. Many diverse traits provide a fitness benefit following fires, and these adaptive traits vary with the fire regime. Some of these traits enhance fire survival, while others promote recruitment in the postfire environment. Demonstrating that these traits are fire adaptations is challenging, since many arose early in the paleontological record, although increasingly better fossil records and phylogenetic analysis make timing of these trait origins to fire more certain. Resprouting from the base of stems is the most widely distributed fire-adaptive trait, and it is likely to have evolved under a diversity of disturbance types. The origins of other traits like serotiny, thick bark, fire-stimulated germination, and postfire flowering are more tightly linked to fire. Fire-adaptive traits occur in many environments: boreal and temperate forests, Mediterranean-type climate (MTC) shrublands, savannas, and other grasslands. MTC ecosystems are distinct in that many taxa in different regions have lost the resprouting ability and depend solely on postfire recruitment for postfire recovery. This obligate seeding mode is perhaps the most vulnerable fire-adaptive syndrome in the face of current global change, particularly in light of increasing anthropogenic fire frequency.

Over the past decade, a new set of methods for estimating dated trees has emerged. Originally referred to as the fossilized birth–death (FBD) process, this single model has expanded to a family of models that allows researchers to coestimate evolutionary parameters (e.g., diversification, sampling) and patterns alongside divergence times for a variety of applications from paleobiology to real-time epidemiology. We provide an overview of this family of models. We explore the ways in which these models correspond to methods in quantitative paleobiology, as the FBD process provides a framework through which neontological and paleontological approaches to phylogenetics and macroevolution can be unified. We also provide an overview of challenges associated with applying FBD models, particularly with an eye toward the fossil record. We conclude this piece by discussing several exciting avenues for the inclusion of fossil data in phylogenetic analyses.

The study of individual behavioral variation, sometimes called animal personalities or behavioral types, is now a well-established area of research in behavioral ecology and evolution. Considerable theoretical work has developed predictions about its ecological and evolutionary causes and consequences, and studies testing these theories continue to grow. Here, we synthesize the current empirical work to shed light on which theories are well supported and which need further refinement. We find that the major frameworks explaining the existence of individual behavioral variation, the pace-of-life syndrome hypothesis and state-dependent feedbacks models, have mixed support. The consequences of individual behavioral variation are well studied at the individual level but less is known about consequences at higher levels such as among species and communities. The focus of this review is to reevaluate and reestablish the foundation of individual behavioral variation research: What do we know? What questions remain? And where are we going next?

We review transitions between hermaphroditism and dioecy in animals and (mainly flowering) plants. Although hermaphroditism and dioecy represent two end states in a sex-allocation continuum, both vary in major ways among clades. However, drawing on sex-allocation theory and distinguishing between self-fertilization and outcrossing, we recognize five broad paths to dioecy and two broad paths to hermaphroditism. Which path is taken likely depends on the starting state (especially in terms of the mating system), as well as the ecological setting or genetic context of the transition. Androdioecy may have been more important in some transitions to dioecy than current theory would suggest, and gynodioecy may often be an evolutionary end point in itself rather than a step between hermaphroditism and dioecy. Transitions between environmental and genetic sex determination may also play an important role in sexual-system evolution. Further theory is required to address these possibilities. Detailed empirical work is also greatly needed, especially in animal clades that vary in their sexual system.

The ability to reproduce is the key trait that distinguishes living organisms from inorganic matter, and the strategies used to achieve successful reproduction are almost as diverse as the organisms themselves. In animals, the most widespread form of reproduction involves separate male and female sexes: Each sex produces haploid gametes via meiosis, and two gametes fuse to form a new diploid organism. In some cases, both parents contribute equally to the nuclear and cytoplasmic genomes of their offspring. However, such fully symmetric reproduction of both parents represents the extreme end of a continuum toward complete asymmetry, where offspring inherit their nuclear and cytoplasmic genomes from only one of the two parents. Asymmetries also occur with respect to the fate of maternally and paternally inherited genomes and which sex is affected by non-Mendelian inheritance. In this review, we describe the diversity of animal reproductive systems along different axes with a symmetry–asymmetry continuum and suggest evolutionary routes that may have led to increased levels of asymmetry.

Fungi play key roles in ecosystems and human societies as decomposers, nutrient cyclers, mutualists, and pathogens. Estimates suggest that roughly 3–13 million fungal species exist worldwide, yet considerable knowledge gaps exist regarding the mechanisms and consequences, both ecological and social, of fungal dispersal from local to global scales. In this review, we summarize concepts underlying fungal dispersal, review recent research, and explore how fungi possess unique characteristics that can broaden our understanding of general dispersal ecology. We highlight emerging frontiers in fungal dispersal research that integrate technological advances with trait-based ecology, movement ecology, social–ecological systems, and work in unexplored environments. Outstanding research questions across these themes are presented to stimulate theoretical and empirical research in fungal dispersal ecology. Advances in fungal dispersal will improve our understanding of fungal community assembly and biogeography across a range of spatial scales, with implications for ecosystem functioning, global food security, and human health. Expected final online publication date for the Annual Review of Ecology, Evolution, and Systematics, Volume 53 is November 2022.
