University leadership framed the dual appointment as a deliberate alignment between the recruits' expertise and UVic's existing institutional priorities. Lisa Kalynchuk, UVic's vice-president research and innovation, said the university is delighted to welcome what she described as two outstanding global leaders, noting that the new chair appointments align strongly with the institution's ambitions in ocean science and mental health. According to Kalynchuk, Hazen and Almeida are expected to strengthen the university's research community, catalyze new collaborations, and help address urgent global challenges. The pairing of a climate-focused ocean scientist with a specialist in everyday stress and aging reflects a coordinated strategy rather than two isolated hires, positioning UVic to expand simultaneously in environmental stewardship and population health—two areas where Canadian research funding has increasingly emphasized prevention, resilience, and real-world impact.

The announcement also arrives at a moment when the competition for senior academic talent has intensified internationally. Universities in the United States, Europe, and Asia continue to pursue the same relatively small pool of established scholars, and national governments have responded by creating dedicated recruitment instruments with multi-year funding guarantees. Canada's approach through the Global Impact+ framework is intended to give domestic institutions the financial capacity to make offers competitive with those from large American research universities and well-funded European institutes. For a mid-sized Canadian university such as UVic, securing two chairholders of this seniority in a single announcement represents a notable outcome of that strategy, and it signals to other prospective recruits that the institution can support ambitious, long-horizon research programs.

Hazen joins UVic following a 12-year career leading climate and ecosystem programs at NOAA's Southwest Fisheries Science Center, one of the leading American research institutions for marine fisheries and ecosystem science. More recently, he held a professorship at the University of Aarhus in Denmark, giving him research experience on both sides of the Atlantic and across two national scientific systems. That background in large-scale government science, combined with his recent international academic posting, positions him to bridge the operational needs of fisheries managers with the analytical tools of academic ecology. Scientists who have worked inside federal fisheries agencies tend to understand the regulatory constraints, data requirements, and political realities that determine whether scientific advice actually changes management decisions—experience that is often difficult to acquire in a purely academic career. At UVic, he will lead research aimed at improving what he and the university describe as climate-ready ocean stewardship, built on real-time data streams and sustained partnerships with government agencies and Indigenous communities along the Pacific coast.

The central ambition of Hazen's chair, as he describes it, is a fundamental shift in how marine resources are governed. "The goal is to shift marine governance from reactive to proactive," Hazen said in the announcement. Rather than responding only after a fisheries collapse, after whales become entangled in fishing gear or are struck by ships, or after climate-driven disruptions reshape human uses of the ocean, Hazen argues that managers should be able to identify early ecosystem warning signals and anticipate risk in near-real time. This approach—sometimes described in the ecological literature as ecosystem-based forecasting—depends on continuous environmental monitoring, rapid data integration, and decision-making frameworks that allow regulators to act before damage occurs rather than documenting it afterward. The Pacific coast, with its busy shipping lanes, valuable fisheries, and recovering whale populations, offers a demanding test case for such a system. Warming waters, shifting species distributions, and increasing vessel traffic have already forced managers in the region to adapt quickly, and the pace of climate-driven change is expected to outstrip the capacity of traditional assessment cycles that update stock evaluations only every few years.

To build that capacity, Hazen's research will draw on an unusually broad network of collaborators. The announcement names Ocean Networks Canada, the University of Victoria-based organization that operates cabled ocean observatories capable of streaming continuous data from the seafloor, along with Fisheries and Oceans Canada, Environment and Climate Change Canada, and Dalhousie University in Nova Scotia. The involvement of Ocean Networks Canada is particularly significant for the technical feasibility of the vision: cabled observatories can deliver power and high-bandwidth data to instruments on the seafloor year-round, something battery-powered autonomous platforms cannot match, enabling the kind of sustained, high-frequency monitoring that near-real-time forecasting requires. Indigenous communities are also named as core partners, and the announcement is explicit that the work will integrate Indigenous knowledge and data sovereignty principles. Data sovereignty—the right of Indigenous nations to govern the collection, ownership, and use of data about their territories and resources—has become an increasingly prominent consideration in Canadian environmental research, and its inclusion as a stated design principle rather than an afterthought signals how the program intends to structure its partnerships. The stated goal is to support climate-responsive ocean stewardship that combines Western scientific monitoring with Indigenous knowledge systems.

The second chair takes UVic in a very different direction: into the daily lives of people long before they become patients. David Almeida joins the university from Pennsylvania State University, where he was a distinguished professor of human development and family studies. Over his career, Almeida has become known for research that examines how small, everyday experiences—daily stressors, fluctuations in mood, sleep quality, and moment-to-moment emotional states—accumulate over years and decades to shape long-term health. His work has helped establish that it is not only major life events, such as job loss or bereavement, that influence health trajectories, but also the accumulation of minor daily hassles and the ways individuals respond to them. At UVic, he will establish a digital and community-based research hub that uses mobile and wearable technologies to measure changes in stress, mood, sleep, and cognition in everyday settings, rather than relying solely on clinic-based assessments that capture only a snapshot of a person's functioning.

Almeida's rationale for this prevention-first approach is that the origins of most health problems lie far upstream of the health care system. "Most health challenges don't begin in hospitals," he said. "They develop gradually through the accumulation of everyday experiences." By combining detailed daily measurements with biological indicators and real-world implementation, he argues, researchers can identify risk trajectories years before clinical impairment becomes established. In his view, this prevention-first approach has the potential to transform how mental health is monitored and supported across the lifespan. The methodological foundation for such work—often called intensive longitudinal or ecological momentary assessment—uses smartphone surveys and wearable sensors to collect dense streams of data from participants as they go about ordinary life, producing a far richer picture of health dynamics than annual check-ups can provide. The approach has grown rapidly in feasibility over the past decade as smartphone ownership has become nearly universal and consumer wearables capable of tracking sleep, heart rate, and activity have proliferated, allowing researchers to study thousands of measurement points per person rather than a handful.

The scientific scope of Almeida's chair extends across several of the most pressing health challenges facing aging populations. His research at UVic will examine connections between daily experiences and long-term outcomes related to mental health, cognitive decline, aging, and cardiometabolic disease—the cluster of conditions including heart disease, stroke, and diabetes that are among the leading causes of illness and death in Canada and other wealthy nations. By linking fine-grained daily data to these downstream outcomes, the research aims to detect early warning signs analogous to those Hazen seeks in ocean ecosystems: subtle shifts in an individual's daily stress reactivity, sleep architecture, or cognitive performance that may foreshadow serious illness years later. Beyond the laboratory, Almeida also plans to build a network of researchers, community organizations, health care providers, and policy leaders to accelerate the adoption of prevention-focused approaches in practice, not just in academic journals—a translation step that prevention research has historically struggled to achieve.

Through this work, the university says, UVic will help advance Canada's leadership in prevention-focused mental health and aging science while supporting innovative approaches to improving health and well-being. The framing reflects a broader shift in Canadian health research policy toward upstream intervention—investing in the identification of risk before disease onset rather than the treatment of established illness. It also aligns with the federal government's stated interest in recruiting international talent through the Canada Global Impact+ Research Talent Initiative, of which the Eddie Goldenberg Research Chairs of Canada program is a component. The initiative is designed to support Canadian institutions in competing for leading researchers from around the world, an increasingly competitive arena as universities in the United States, Europe, and Asia vie for the same small pool of senior scholars.

The two appointments also illustrate a shared methodological theme that cuts across the university's ocean and health portfolios: the use of continuous, real-world data streams to anticipate problems before they become crises. Hazen's vision of near-real-time ocean management and Almeida's vision of daily-life health monitoring both depend on sensing technologies, longitudinal data collection, and analytical frameworks capable of turning high-frequency information into actionable early warnings. Both chairs likewise emphasize partnership beyond the academy—with government agencies and Indigenous communities in the marine case, and with community organizations, clinicians, and policymakers in the health case. That convergence suggests UVic sees anticipatory, data-rich, partnership-based science as a unifying institutional identity, one it hopes the $16 million investment will help cement.

As with any announcement of this kind, the details of how the research will unfold remain to be seen. The release describes broad research directions, named collaborators, and intended approaches, but specific projects, timelines, staffing, and measurable outcomes have not yet been laid out. The success of Hazen's program will depend on sustained coordination among multiple federal departments, a university-based observatory organization, and Indigenous partners with their own governance priorities, while Almeida's hub will need to recruit participants, secure ethical approvals for intensive digital data collection, and demonstrate that daily-life measurements can meaningfully predict clinical outcomes.

Using extensive field observations from both seas, the team ranked Red Sea species by invasion potential and highlighted three particularly high-risk candidates: the stellate pufferfish (Arothron stellatus), the cinnabar goatfish (Parupeneus heptacantha), and the yellowspotted trevally (Turrum fulvoguttatum).

The work, led by Dr. Shahar Chaikin under the supervision of Prof. Jonathan Belmaker, was published in the Journal of Animal Ecology and aims to move beyond explaining past invasions toward anticipating future ones—especially as Mediterranean warming accelerates the northward movement of tropical species.

To generate the evidence base for their model, the scientists deployed stereoscopic baited remote underwater video systems (stereo-BRUVs) across depths from 5 to 150 meters in the Gulf of Eilat and along Israel’s Mediterranean coast. They then analyzed hundreds of hours of footage covering 179 fish populations.

A key technical result overturned a common expectation: invasion success was not best predicted by whether a species is a “generalist” that tolerates many habitats. Instead, the strongest predictor was its lack of dependence on coral reefs.

Dr. Chaikin explains that the Mediterranean contains far fewer coral reef habitats than the Red Sea. Fish that rely on coral reefs are therefore less likely to complete the journey through the corridor of unsuitable conditions, whereas reef-independent species are more likely to establish.

The study also quantified behavioral shifts after arrival. Rather than retaining Red Sea habitat choices, successful migrants rapidly reconfigure their preferences to exploit resources available in the Mediterranean environment.

Importantly, the researchers found that invaders do not necessarily occupy “empty” ecological niches. They often use the same habitats as native species, implying intensified competition for food, shelter, and space—an effect likely to reshape local community dynamics.

Finally, the authors argue that “watchlists” derived from models like theirs could support early detection and improve management decisions. As conditions warm, predictive frameworks may become an essential tool for protecting marine ecosystems before new species become entrenched.

Sponges, often seen as simple filter feeders inhabiting a wide range of aquatic environments from shallow coastal canals to the abyssal depths, have a surprisingly sophisticated relationship with nitrogen. Nitrogen, an essential element for life, moves through ecosystems in various chemical forms. Understanding how sponges process nitrogen involves tracking stable isotopes of this element, but previous studies have only scratched the surface. Notably, the nitrogen isotope profiles of glass sponges—Hexactinellida—reveal unexpected patterns that challenge earlier assumptions about their feeding ecology and biochemical interactions with their surroundings.

Large sponge biomasses in certain marine regions can profoundly modulate local biogeochemical cycles, particularly nitrogen availability. These ancient animals establish symbiotic communities with diverse microorganisms capable of mediating critical nitrogen transformations, such as nitrification, denitrification, and nitrogen fixation. Dr. Stratmann’s work leverages advanced methodologies, including the deployment of incubation chambers in situ at extreme depths of around 4,000 meters, to quantify these microbial-mediated nitrogen fluxes within sponge microhabitats. Such deep-sea investigations are logistically challenging but essential, as traditional surface-based observations cannot capture the authentic metabolic dynamics of glass sponges.

Prior expeditions off New Zealand and in the Central Pacific have laid the groundwork for such studies, enabling direct measurement of nitrogen cycling in natural deep-sea sponge communities. The incubation chambers isolate individual sponges and their surrounding water, allowing precise monitoring of chemical exchanges over several days. These data elucidate the metabolic rates and pathways by which sponges and their symbionts transform various nitrogen species, offering unprecedented insight into their ecological functions and contributions to marine nitrogen budgets.

Yet, Dr. Stratmann’s research transcends contemporary ecosystems. She pioneers an innovative approach to investigating nitrogen cycling in fossilized sponges, analyzing nitrogen-containing organic compounds preserved in ancient skeletal structures. By extracting these molecular remnants and determining their isotopic signatures, her team can reconstruct nitrogen metabolic pathways from bygone geological epochs. This palaeobiogeochemical perspective holds the key to unravelling historical oceanic nutrient dynamics and environmental conditions that shaped marine ecosystems over hundreds of millions of years.

Decoding nitrogen cycling in fossil sponges not only informs about the organisms themselves but also generates proxies for past marine environmental variables such as oxygenation levels, nutrient availability, and microbial activity. These insights are critical in piecing together Earth’s climatic and biogeochemical evolution. Dr. Stratmann collaborates with natural history museums across Europe, tapping into their extensive sponge collections to extend her temporal reach and establish a robust dataset spanning diverse geological periods.

Returning to her alma mater, the University of Bremen, Dr. Stratmann is supported by MARUM – the Center for Marine Environmental Sciences – which provides cutting-edge facilities indispensable for executing her multidisciplinary research. MARUM’s capabilities in biogeochemical analyses and oceanographic instrumentation uniquely position her group to address complex questions at the intersection of marine biology, chemistry, and earth sciences. Beginning in February 2026, she will lead her project from Bremen, fostering collaborations and continuing deep-sea research missions.

The significance of this work extends beyond academic curiosity. Sponges represent key benthic organisms that shape ecosystem functioning and influence global biogeochemical cycles, including those regulating greenhouse gases and nutrient fluxes. Understanding their nitrogen metabolism is vital, especially as benthic habitats face mounting threats from climate change, ocean acidification, and human exploitation. Insights gained here will contribute to predictive models of marine ecosystem responses under future environmental scenarios.

Dr. Stratmann’s project was recently awarded the prestigious ERC Starting Grant, a highly competitive funding scheme recognizing exceptional early-career researchers. This grant facilitates three to five years of independent research, supporting high-risk, high-reward scientific inquiries that push boundaries. Among nearly 4,000 applicants across Europe, her selection underscores the innovative scope and potential impact of her investigations into ancient and modern marine nitrogen cycling.

The commitment of researchers like Dr. Stratmann reflects a broader scientific effort to decode the complex interplay of biological, chemical, and geological processes that govern life on Earth. By bridging observational studies in contemporary marine environments with palaeontological analyses, this research promises to deepen our understanding of the evolutionary history of nitrogen cycling and its implications for marine ecology throughout time.

Moreover, the collaborative ethos embodied by MARUM and its researchers exemplifies the integration of fundamental research with societal responsibility. The center’s dedication to open data, sustainability, and dialogue bridges the gap between science and public engagement, ensuring that discoveries in marine environmental sciences translate into actionable knowledge for environmental stewardship.

In conclusion, the exploration of nitrogen cycling in both living sponges and their fossil relatives offers a novel window into the intricate biochemical networks underlying Earth’s marine ecosystems. Dr. Stratmann’s multifaceted approach combining deep-sea fieldwork, stable isotope analyses, and palaeobiochemistry heralds a new era of marine biogeochemical research. These studies have the potential to reshape our conception of early animal evolution, terrestrial nutrient cycles, and the resilience of oceanic life through global environmental shifts.

Since its mysterious onset in 2013, SSWD has decimated sea star populations, with the sunflower sea star (Pycnopodia helianthoides) receiving the harshest blow. These remarkable creatures, capable of growing as large as a bicycle tire with up to 24 arms, have faced over 90 percent population loss across their broad range stretching from the shores of Alaska down to Mexico. This catastrophic decline has not only pushed the sunflower sea star to the brink of extinction but has also set off a cascade of ecological shifts that ripple through coastal food webs.

The protracted hunt for the cause of SSWD culminated in a meticulous four-year investigation involving international collaboration among scientists from the Hakai Institute, University of British Columbia, University of Washington, and various conservation organizations. Researchers first sifted through an array of potential pathogens, including viruses, but the breakthrough came with the identification of abnormally high concentrations of Vibrio pectenicida in the coelomic fluid—often described as the “blood” of sea stars—of diseased individuals. This microbe was ultimately proven to be the direct agent causing the disease, as experiments confirmed that injecting cultured V. pectenicida strain FHCF-3 into healthy sea stars triggered the rapid onset of wasting symptoms and death.

Vibrio bacteria belong to a notorious genus known for their devastating impacts across diverse marine species and even humans—for instance, Vibrio cholerae is the well-known cause of cholera. The pathogenic strain Vibrio pectenicida has previously been documented in shellfish epidemics, driving swift and fatal infections in scallop larvae. Its addition to the roster of marine pathogens adds a new layer of urgency to the study of marine microbial ecology and the increasing vulnerability of ocean life to diseases.

SSWD’s clinical progression is alarming and swift. Once infected with V. pectenicida FHCF-3, sea stars develop visible lesions and a grotesque “melting” of tissue that unfolds over about two weeks. Affected individuals often show characteristic contortion and arm loss, a physically debilitating manifestation that leaves no doubt about the severity of the infection. For species like the already beleaguered sunflower sea star, these symptoms spell ecological disaster, as population crashes diminish their critical role as predators of kelp-grazing sea urchins.

Ecologists emphasize the broader repercussions of the sea star collapse. Melanie Prentice, evolutionary ecologist and lead author of the study, highlights how the loss of billions of sea stars has inadvertently allowed sea urchin populations to explode. This surge in urchins has led to overgrazing of kelp forests, stripping away habitats that serve thousands of marine species and depriving coastal communities of economic and ecological benefits. Kelp forests are not merely underwater greenery; they function as essential carbon sinks, safeguard shorelines against erosion and storms, and form an integral cornerstone of cultural identity for many Indigenous peoples.

The discovery of V. pectenicida as the causative agent allows scientists to pivot from diagnosing the problem to innovating solutions. By having a concrete pathogen in focus, researchers and conservationists can now develop diagnostic tests akin to those used during human pandemics, enabling early detection and monitoring in wild and captive sea star populations. Such targeted approaches could revolutionize recovery attempts, facilitating safer translocations, breeding programs, and even experimental reintroduction efforts.

Furthermore, the study opens avenues for exploring environmental factors that exacerbate the disease. Alyssa Gehman, senior author and marine disease ecologist, notes the strong correlation between Vibrio bacteria and warmer ocean temperatures. Given that Vibrio proliferates dramatically during marine heatwaves, the rising frequency and intensity of ocean warming under climate change raise urgent questions about disease dynamics. The possibility that colder, more stable marine environments like British Columbia’s fjords could serve as refuges for vulnerable species adds a hopeful dimension to conservation planning.

The implications of this research extend beyond sea stars. It exemplifies how marine microbial pathogens can reshape ecosystems in profound ways, underscoring the intricate connections between disease, climate, and biodiversity. As marine heatwaves become more common, understanding the temperature sensitivity of pathogens like V. pectenicida is critical for predicting future outbreaks and establishing proactive management strategies.

With the causative agent identified, multi-institutional teams are now developing innovative interventions. These include evaluating probiotics and phage therapy to counteract bacterial infections, protocols for screening and quarantining sea stars before reintroduction, and genetic studies aimed at discovering disease resistance among individual sea stars. Captive breeding and controlled outplanting programs are underway, poised to replenish populations in regions where recovery is feasible.

The collaborative effort behind this discovery is notable. Institutions spanning academic, governmental, and conservation sectors combined expertise and resources to achieve this milestone. Funders such as The Nature Conservancy and the Tula Foundation facilitated the extensive laboratory and field research conducted at the University of British Columbia and the U.S. Geological Survey’s Marrowstone Marine Field Station.

Beyond the scientific breakthrough, this story carries a broader message about the importance of understanding marine diseases and their intersection with environmental change. As scientists like Melanie Prentice draw parallels with human experiences during the COVID-19 pandemic, the newfound capacity to test for SSWD gives conservationists a powerful tool to make informed decisions, avoid unintended spread of pathogens, and devise adaptive interventions.

This discovery heralds a new chapter in marine ecology and conservation. By pinpointing Vibrio pectenicida as the microbial pathogen behind sea star wasting disease, scientists have illuminated a critical threat and laid the foundation for restoring both a keystone species and the fragile ecosystems that depend on it. The journey from mystery to understanding exemplifies the power of rigorous science and international cooperation in confronting environmental crises and underscores hope for a future where once-thriving kelp forests and their vibrant marine communities can recover and flourish.
