Plants and herbivores are remarkably variable in space and time, and variability has been considered a defining feature of their interactions. Empirical research, however, has traditionally focused on understanding differences in means and overlooked the theoretically significant ecological and evolutionary roles of variability itself. We review the literature with the goal of showing how variability-explicit research expands our perspective on plant–herbivore ecology and evolution. We first clarify terminology for describing variation and then review patterns, causes, and consequences of variation in herbivory across scales of space, time, and biological organization. We consider how incorporating variability improves existing hypotheses and leads to new ones. We conclude by suggesting future work that reports full distributions, integrates effects of variation across scales, describes nonlinearities, and considers how stochastic and deterministic variation combine to determine herbivory distributions. Expected final online publication date for the Annual Review of Ecology, Evolution, and Systematics, Volume 54 is November 2023.

The origin of life entails a continuum from simple prebiotic chemistry to cells with genes and molecular machines. Using life as a guide to this continuum, we consider how selection could promote increased complexity before the emergence of genes. Structured, far-from-equilibrium environments such as hydrothermal systems drive the reaction between CO2 and H2 to form organics that self-organize into protocells. CO2 fixation within protocells generates a reaction network with a topology that prefigures the universal core of metabolism. Positive feedback loops amplify flux through this network, giving a metabolic heredity that promotes growth. Patterns in the genetic code show that genes and proteins arose through direct biophysical interactions between amino acids and nucleotides in this protometabolic network. Random genetic sequences template nonrandom peptides, producing selectable function in growing protocells. This context-dependent emergence of information gives rise seamlessly to an autotrophic last universal common ancestor.

Terrestrial ecosystems encompass a vast and vital component of Earth's biodiversity and ecosystem services. The effect of increased anthropogenic dominance on terrestrial communities defines major challenges for ecosystem conservation, including habitat destruction and fragmentation, climate change, species invasions and extinctions, and disease spread. Here, we integrate fossil, historical, and present-day organismal and ecological data to investigate how conservation paleobiology provides deep-time perspectives on terrestrial organisms, populations, communities, and ecosystems impacted by anthropogenic processes. We relate research tools to conservation outputs and highlight gaps that currently limit conservation paleobiology from reaching its full impact on conservation practice and management. In doing so, we also highlight how the colonial legacies of conservation biology and paleobiology confound our understanding of present-day biodiversity, ecosystem processes, and conservation outlooks, and we make recommendations for more inclusive and ethical practices moving forward.

Greenhouse gas emissions are warming the ocean with profound consequences at all levels of organization, from organismal rates to ecosystem processes. The proximate driver is an interplay between anthropogenic warming (the trend) and natural fluctuations in local temperature. These two properties cause anomalously warm events such as marine heatwaves to occur with increasing frequency and magnitude. Because warming and variance are not uniform, there is a large degree of geographic variation in temporal temperature variability. We review the underappreciated interaction between trend and variance in the ocean and how it modulates ecological responses to ocean warming. For example, organisms in more thermally variable environments are often more acclimatized and/or adapted to temperature extremes and are thus less sensitive to anthropogenic heatwaves. Considering both trend and variability highlights the importance of processes like legacy effects and extinction debt that influence the rate of community transformation.

Large Old World fruit bats (LOWFBs), species of Pteropus, Acerodon, and related genera of large bats in the pteropodid subfamily Pteropodinae, play important roles as agents of dispersal and pollination across the Paleotropics. LOWFBs are also collectively the most threatened group of bats in the world, with 71% of extant species assessed as threatened by the International Union for the Conservation of Nature. As highlighted here, contrary to other bats, the vast majority of LOWFBs face multiple simultaneous threats. Most importantly, biological and ecological traits, in particular life history characteristics, diet, movement, social ecology, and physiology, intensify threats and accelerate species declines. Furthermore, we demonstrate that LOWFBs are to be considered keystone species and express concern about the erosion of this role and the cascading effects expected on native ecosystems. In response to this alarming situation, we advance general recommendations and identify overarching research and conservation actions.

Pollination is an essential component of plant reproduction that is transformed by the novel environmental conditions in cities. We summarize patterns of urban plant reproduction and trace the mechanisms by which urban environments influence pollination, beginning at the level of the individual plant. We then progress through several processes unique to animal-pollinated plants, including plant–pollinator signaling, community-level effects, and emergent plant–pollinator interaction networks. Last, we review pollen movement and plant spatial mating networks. Despite a global signal of reduced pollination in urban, animal-pollinated plants, effects vary among studies, and the extent of pollen dispersal through a city remains difficult to predict. We highlight recent progress, as well as areas where new research will help crystallize our understanding of urban pollination. These advances have the potential to spur exciting new insights into network dynamics and pollen movement, and may ultimately inform the sustainable design of urban conservation and ecosystem services.

Biological toxins are entrenched within ecosystems. Thus, animals are often exposed to such toxins, and how they adapt can be a key determinant of their evolutionary trajectories. In this review, we provide an overview of the diversity of toxin resistance mechanisms, with a focus on animals that sequester toxins from their diet and their natural predators and parasites. We propose a structured framework in which to study toxin resistance by recategorizing and reorganizing known mechanisms into avoidance, metabolism, and target categories. Then, using this framework, we review evidence regarding how animals resist four widely studied compounds: tetrodotoxin, batrachotoxin, cardiac glycosides, and pyrrolizidine alkaloids. Based on the available data, we conclude that toxin resistance and sequestration are interrelated from both ecological and evolutionary perspectives. To conclude, we highlight open questions regarding toxin resistance and review its importance as a field. En los ecosistemas las toxinas de origen biológico son componentes intrínsecos.

Functional trait–based mediation of animal invasions is only now developing, yet it is already showing as much promise as the approach has for plant invasion biology. Here, we provide a theory-founded examination of functional trait-based ecology with respect to animal invasions, together with a review of the empirical research. Recent developments in the scaling of traits to ecosystems, along with the frameworks for invasion ecology, provide a powerful foundation for investigations. Despite growing empirical research in this field, interspecific comparisons incorporating comparative phylogenetic approaches remain uncommon, and those examining assemblages are even more so. Despite the importance of time since introduction, it is rarely included in studies. Broad environmental tolerances, life history traits associated with fast growth or greater reproduction, and in some cases, greater phenotypic plasticity of traits, mediate the success of animal alien species at various stages of invasion, although introduction effort remains one of the most important factors affecting success.

Density-dependent selection, which promotes contrasting patterns of trait means at different population densities, has a long history in population genetics and ecology. The unifying principle from theory is that density-dependent selection operates on phenotypic traits whose values counter the effects of whatever ecological agent is limiting population growth, be it resource competition, predators, or pathogens. However, the complexity inherent in density dependence means that the same selective process can generate multiple outcomes, depending upon the details of how population density affects vital rates and the age or size structure of a population. Failure to appreciate the potential for multiple outcomes confounded many early studies of the process. Nonetheless, careful empirical work in laboratory studies, long-term field studies, and studies of sexual selection demonstrates the wide reach of density-dependent selection. The inconsistent outcomes observed in these studies call for renewed research into how the details of density dependence channel adaptive responses.

The coronavirus disease 2019 (COVID-19) pandemic challenged the workings of human society, but in doing so, it advanced our understanding of the ecology and evolution of infectious diseases. Fluctuating transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) demonstrated the highly dynamic nature of human social behavior, often without government intervention. Evolution of SARS-CoV-2 in the first two years following spillover resulted primarily in increased transmissibility, while in the third year, the globally dominant virus variants had all evolved substantial immune evasion. The combination of viral evolution and the buildup of host immunity through vaccination and infection greatly decreased the realized virulence of SARS-CoV-2 due to the age dependence of disease severity. The COVID-19 pandemic was exacerbated by presymptomatic, asymptomatic, and highly heterogeneous transmission, as well as highly variable disease severity and the broad host range of SARS-CoV-2. Insights and tools developed during the COVID-19 pandemic could provide a stronger scientific basis for preventing, mitigating, and controlling future pandemics. Expected final online publication date for the Annual Review of Ecology, Evolution, and Systematics, Volume 54 is November 2023.
