Disagreements extend to the nature of oxygen bioavailability and whether oxygen usually limits growth under warming, explaining smaller adult size. These controversies affect two influential hypotheses: gill oxygen limitation and oxygen- and capacity-limited thermal tolerance. Here, we promote deeper integration of physiological and evolutionary mechanisms. We first clarify the nature of oxygen bioavailability in water, developing a new mass-transfer model that can be adapted to compare warming impacts on organisms with different respiratory systems and flow regimes. By distinguishing aerobic energy costs of moving oxygen from environment to tissues from costs of all other functions, we predict a decline in energy-dependent fitness during hypoxia despite approximately constant total metabolic rate before reaching critically low environmental oxygen. A new measure of oxygen bioavailability that keeps costs of generating water convection constant predicts a higher thermal sensitivity of oxygen uptake in an amphipod model than do previous oxygen supply indices. More importantly, by incorporating size- and temperature-dependent costs of generating water flow, we propose that oxygen limitation at different body sizes and temperatures can be modeled mechanistically. We then report little evidence for oxygen limitation of growth and adult size under benign warming. Yet occasional oxygen limitation, we argue, may, along with other selective pressures, help maintain adaptive plastic responses to warming. Finally, we discuss how to overcome flaws in a commonly used growth model that undermine predictions of warming impacts.</p>","PeriodicalId":55376,"journal":{"name":"Biological Bulletin","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10433057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For aquatic organisms, the consequences are poorly known but are likely to reflect both direct effects of declining oxygen bioavailability and interactions between oxygen and other stressors, including two—warming and acidification—that have received substantial attention in recent decades and that typically accompany oxygen changes. Drawing on the collected papers in this symposium volume (“An Oxygen Perspective on Climate Change”), we outline the causes and consequences of declining oxygen bioavailability. First, we discuss the scope of natural and predicted anthropogenic changes in aquatic oxygen levels. Although modern organisms are the result of long evolutionary histories during which they were exposed to natural oxygen regimes, anthropogenic change is now exposing them to more extreme conditions and novel combinations of low oxygen with other stressors. Second, we identify behavioral and physiological mechanisms that underlie the interactive effects of oxygen with other stressors, and we assess the range of potential organismal responses to oxygen limitation that occur across levels of biological organization and over multiple timescales. We argue that metabolism and energetics provide a powerful and unifying framework for understanding organism-oxygen interactions. Third, we conclude by outlining a set of approaches for maximizing the effectiveness of future work, including focusing on long-term experiments using biologically realistic variation in experimental factors and taking truly cross-disciplinary and integrative approaches to understanding and predicting future effects.","PeriodicalId":55376,"journal":{"name":"Biological Bulletin","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10433055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Coral health is greatly dependent on complex interactions between the host animal and its associated microbial symbionts. While relatively understudied, there is growing evidence that the coral microbiome contributes to the health and resilience of corals in a variety of ways, similar to more well-studied systems, such as the human microbiome. Many of these interactions are dependent upon the production and exchange of natural products, including antibacterial compounds, quorum-sensing molecules, internal signaling molecules, nutrients, and so on. While advances in sequencing, culturing, and metabolomic techniques have aided in moving forward the understanding of coral microbiome interactions, current sequence and metabolite databases are lacking, hindering detailed descriptions of the microbes and metabolites involved. This review focuses on the roles of coral microbiomes in health and disease processes of coral hosts, with special attention to the coral metabolome. We discuss what is currently known about the relationship between the coral microbiome and disease, of beneficial microbial products or services, and how the manipulation of the coral microbiome may chemically benefit the coral host against disease.

Larvae as organisms has been a focal topic in the journal. While papers on insect and vertebrate larvae were common in the early years, recent volumes mainly address marine larvae. In consideration of the 125th anniversary of the journal, I scanned the first 25 volumes, and I also queried Web of Science (Clavariate Analytics) for the topic “larvae” in The Biological Bulletin. The earliest papers are anatomical and behavioral and cover all animal groups (e.g., bowfin embryos, Prather, 1900. Biol. Bull. 1: 57–80; ant larvae, Wheeler, 1900. Biol. Bull. 2: 1–31; zoanthid larvae, Cary, 1904. Biol. Bull. 7: 75–78; geotropism in sea urchin larvae, Lyon, 1906. Biol. Bull. 12: 21–22; heliotropism in shrimp larvae, Lyon, 1906. Biol. Bull. 12: 23–25). My search of the publication “Biological Bulletin” in Web of Science (back to its start in 1965) returned over 4900 titles (not counting meeting abstracts). Adding “larvae” as a topic returned 741 titles, indicating that 15% of all contributions mention larvae. Three articles on marine larvae are among the top 10 most cited titles in the journal. Two are on larval dispersal (Shanks, 2009. Biol. Bull. 216: 373–385 [496 citations] and Scheltema, 1971. Biol. Bull. 140: 284–322 [451 citations]), and a third is on fertilization in the field (Pennington, 1985. Biol. Bull. 169: 417–430 [444 citations]). I will discuss the two papers on larval dispersal for contrast. Scheltema (1971) addresses the possibility that larvae are transported long distances across the ocean and maintain genetic continuity. In particular, he made this argument for some species of gastropods that are found on both sides of the Atlantic. The study maps where larvae of 10 coastal species were found in plankton samples taken at stations all across the northern Atlantic ocean (Scheltema’s figs. 4–12) in both warm-temperate and tropical waters.

In particular, longfin inshore squid, Doryteuthis pealeii, sometimes called the “Woods Hole squid” (Fig. 1) because they migrate each spring to the waters of Cape Cod, have lured neuroscientists to Woods Hole to study the neurons that control the distinctive jetescape behavior of these animals. In the summer of 1936, the 29-year-old English comparative zoologist John Zachary (JZ) Young (Fig. 2) came to Woods Hole to study the stellate ganglion of squid—in particular that ganglion’s characteristic motor neuron, with its giant axon. This neuron integrates various inputs and, when sufficiently excited, produces an action potential that rapidly travels via its giant axon to the mantle muscles of the squid’s body. There, excitation of circularmuscle fibers causes a contraction of themantle, and the ensuing rapid jet-escape behavior. That summer, Young had three main lines of investigation of these neurons. One was a collaboration with a longtime MBL summer researcher, C. Ladd Prosser, also 29 years old that summer (Fig. 2), in which they studied the physiology of the synapses between these motor giant axons and the circular muscle. Prosser and Young published their work from the summer of 1936 in the next year’s October issue of The Biological Bulletin (“Responses of Muscles of the Squid to Repetitive Stimulation of the Giant Nerve Fibers,” 73: 237–241; Fig. 3). They examined whether the responses of these muscle fibers were facilitating, that is, whether the responses became larger with each of a series of axon potentials.

These pentaradial wonders have been useful for studying basic biology and more recently in understanding effects of climate change and ocean acidification on organisms (Matson et al., 2012. Biol.

We had picked the purple sea urchin and a large barnacle as test organisms. They were good candidates because we could easily sample fluid from their body cavities. The sea urchins were especially easy to sample. And we would measure things that any respiratory and acid-base physiologist would measure. Early in our study, serendipity paid us a visit. I remember David Scholnick, one in our group, walking into the lab, holding a sea urchin, and proclaiming that sea urchins leak water from somewhere for minutes after they are exposed to air. We knew how to sample the fluid, called perivisceral coelomic fluid (PCF), from the main body compartment; and this allowed us to make our measurements.

At the time, the phenomenon of coral bleaching, the paling of coral tissues due to loss of their endosymbiotic dinoflagellate algae (once called zooxanthellae but now known to be members of the diverse family Symbiodiniaceae), was just beginning to be observed and documented in nature and linked to high-temperature anomalies (Glynn, 1990. Elsevier Oceanogr. Ser. 1990: 55–126). Now, 30 years later, we are witnessing the collapse of the world’s coral reefs as climate change drives high-temperature events that cause vast stretches of reef to bleach and ultimately die, resulting in the destruction of the entire ecosystem (vanWoesik et al., 2022.Glob. Change Biol., https://doi.org/10.1111/gcb.16192). Coral biologists the world over are racing to develop solutions to help coral reefs survive in the Anthropocene (National Academies of Sciences, Engineering, and Medicine, 2019. A Research Review of Interventions to Increase the Persistence and Resilience of Coral Reefs). Many of their approaches are based on foundational knowledge of the mechanisms driving coral bleaching (a form of dysbiosis), the area that this seminal paper helped to start. In the study, Gates and colleagues aimed to document the process of symbiont release from hosts at the cellular level. They started by setting up a variety of possibilities for mechanisms of bleaching, in Figure 1. This now-iconic figure (Fig. 1) has been reproduced, modified, and added to innumerable times in both original papers and reviews (e.g., Weis, 2008. J. Exp.
