  1. Meet our group members! Here‘s our next PhD candidate: Melanie Habermann.

    No personal picture this time, but we could share a photo of her cat instead.

    “Hi, I’m Melanie. I'm now in the last months of my PhD and in the middle of thesis writing. My background is in environmental science where I developed a passion for mathematical modeling. I mostly worked with ecological models but am fascinated by all kinds of dynamic and complex systems.

    My work focuses on food webs and how we can use their structure to our advantage. Ever wondered when it is reasonable to reduce a food web to a small group of interacting species because those dominate the dynamics? Me as well! While we can learn a lot from looking at these small groups in isolation, the dynamics can change drastically when the same group is part of a wider network. But for some properties, the dynamics are actually driven by small network motifs.

    Sometimes I also do art and science communication.”

    If you want to know more about her work on food webs, here is a paper arguing for the use of functional motifs: doi.org/10.1073/pnas.2521927123

  2. 🦈 NEW: Researchers are proposing a shift from passive #ocean protection toward active marine #rewilding, outlining principles that include restoring #foodwebs and reintroducing #apexpredators like #sharks.

    The approach emphasizes that human communities are integral parts of coastal #ecosystems rather than entities to be fenced out, and aims to build self-sustaining #habitats equipped to handle #climate shifts and #pollution.

  3. 💁🏻‍♀️ TIL: 🧮🐙 Food webs have resisted easy mapping because traditional #ecology depends on physically collecting species.

    Researchers Naoto Ishikawa and Ettore Barbieri teamed up, pairing #predators two at a time and using Bayes’ theorem to calculate likely meals. Tested against 158 documented #ecosystems, their #algorithm rebuilt invisible #foodwebs with more than 80% accuracy.

  4. A new method for identifying the structure, and trophic transfer coefficients, of food webs uses stable isotope data, pairwise comparisons between species, and Bayesian statistics to reconstruct the entire food web. This performed well over 158 marine food webs, with ROC AUC and balanced accuracy both over 80%.

  5. 📰 America’s Biggest Irrigated Crop Is Lawn Grass 😬

    🌎 U.S.: With **40+ million acres** of turf blanketing the country, experts warn that our yards have become ecological dead zones, in the midst of rapid insect and bird population declines.

    🦋 Native plants otoh feed caterpillars, support specialist insects, and rebuild the energy pathways that lawns erase.

    👉 Dedicate just a corner of your yard to natives and restore the wildlife pantry.
    A single oak, a viburnum, or a patch of goldenrod and coneflower can jump‑start a functioning food web right outside your door.

  6. Many #seabirds are starving to death as a marine #heatwave lingers off #California and #fish seek deeper, cooler waters, scientists say. Scientists fear the die-off of #birds could worsen with #ElNino warming of parts of #Pacific. Die-offs are becoming more frequent as planet warms and #oceans heat up.
    As cold-water species move deeper and farther north, the marine heat wave coupled with El Nino could further disrupt #foodwebs for sea life from gray whales to seabirds.

  9. How to make sustainable seafood choices this Christmas to ease the pressure on Australia’s oceans

    "Last year the market traded about 350 tonnes of seafood over the Christmas period, with 120t of prawns and 70,000 dozen oysters among the top sellers...Australian Marine Conservation Society’s GoodFish guide aims to showcase the most environmentally friendly seafood sources."

    'Sustainable Fishing' is a Lie
    "Fishing sustainability is based on a pseudoscientific theory that justifies taking the most marine life for maximum profit. Sustainable fishing is a deception, a myth motivated by the ideology that life on Earth belongs to humankind."

  11. Global oxygen decline in the ocean
    Ocean hypoxia: The science of climate change in the sea

    "... The field will need to draw on ... advances to meet demands for adaptation solutions to the continued progression of global ocean deoxygenation, particularly in conjunction with ocean acidification and marine heatwaves in a multi-stressor scenario."

    Chan, F., Sokolova, I. & Vopel, K. Ocean hypoxia: The science of climate change in the sea. Sci Rep 15, 4260 (2025). doi.org/10.1038/s41598-025-867

  12. So, something else that is a key element of ensuring #HumanWelfare remains in the SW range is to make sure folks are fed -- without destroying the environment! That's where #RegenerativeAgriculture , #SustainableAgriculture, #FoodForests, #CommunityGardens, etc., come into play. But #Rewilding and restoring key natural systems are also very important!

    7. #Wildlife faces #extinction cascades as #ecosystems collapse.

    "Vertebrate populations have declined by an average of 69 percent since 1970, with some regions experiencing losses exceeding 90 percent as habitat destruction, climate change, #pollution, and direct #exploitation combine to trigger ecosystem-wide collapse that eliminates the #biodiversity necessary to maintain stable #FoodWebs. Species extinction rates now exceed background levels by 100 to 1,000 times, representing a mass extinction event comparable to the asteroid impact that eliminated the dinosaurs but compressed into a timeframe measured in decades rather than millennia.

    "The collapse of insect populations threatens #pollination services essential for agricultural production, while marine ecosystems face #acidification, warming, and #overfishing that eliminate entire trophic levels and destabilize ocean food chains supporting billions of people. Domestic animals face parallel threats as #IndustrialAgriculture concentrates genetic diversity into vulnerable #monocultures while climate change disrupts feed production and increases disease pressure on livestock populations already stressed by intensive production methods designed to maximize short-term yields rather than long-term #resilience."

  13. #NPR: The U.S. takes a step toward allowing #mining on the ocean floor, a fragile #ecosystem

    by Julia Simon, April 25, 2025

    "President #Trump signed an executive order Thursday aimed at making it easier for companies to mine the deep seafloor, saying it would create 'a robust domestic supply for critical minerals.'

    "There is currently no commercial-scale deep-sea mining anywhere in the world. But companies have long eyed the ocean floor as a potential source of metals like nickel, cobalt, manganese and copper, which are used in batteries for electric vehicles and other technologies.

    "The world has no rulebook for deep-sea mining. One company is pushing forward anyway

    "These metals can be found in potato-sized nodules lying on the ocean floor. Many of the nodules are in the middle of the Pacific ocean, beyond the legal territory of individual countries.

    "Thursday's order might circumvent ongoing international negotiations to regulate deep-sea mining.

    "Those regions have traditionally been overseen by an international organization, the #InternationalSeabedAuthority (#ISA). The ISA has hosted talks for years to try to hammer out a rulebook to govern a potential seabed mining industry. The U.S. did not ratify the treaty that governs the seabed, and is not a voting member of the ISA, though in the past under previous administrations it has respected the ISA process.

    "In his executive order, Trump instructed federal agencies to expedite the process for reviewing and issuing permits for mining on the seafloor in both U.S. and international territory. It will use a U.S. law from 1980, the "#DeepSeabed Hard Mineral Resources Act."

    "Scientists and environmental groups condemned the order, arguing that opening the deep seabed for mining could disrupt important marine ecosystems, and damage the fishing industry.

    " 'This is being planned on some of the least resilient #ecosystems on the planet,' says Douglas McCauley, professor of ocean science at the University of California Santa Barbara. 'It would have #catastrophic biological consequences.'

    "Underwater mining can create plumes of sediment that could suffocate marine life, and degrade the #FoodWebs that fish depend on, McCauley says.

    "There are also important questions about whether we actually need to be mining the seabed to get enough of these minerals for technologies like batteries, says Micah Ziegler, assistant professor of energy and chemical systems at Georgia Institute of Technology.

    "While a couple of years ago researchers were concerned about the limitations of land-based mining for metals like cobalt and nickel, a variety of alternative #battery chemistries have been developed that might reduce the need for those elements, Ziegler says."

  14. Scientists found a way to clean up #methylmercury, a dangerous pollutant that builds up in our #environment due to human activities. Fish & flies can be engineered to break down this form of #mercury and remove it from their bodies as a less harmful gas, tackling related #pollution & #foodsafety issues. Species at the top of #foodwebs, incl. humans, can accumulate #mercury at levels that harm neural & reproductive health: lighthouse.mq.edu.au/article/f #health #synbio

  15. #Ocean #heat is changing #marine #foodwebs – with far-reaching consequences for NZ #fisheries and #sea life
    Warming is already threatening #coralreefs – #GreatBarrierReef is hottest it’s been in 400 years – and marine life. But it is also reshaping #ecosystems at the very basis of #ocean food webs. Scientists are observing a downward trend in #phytoplankton leading to expanding “ocean deserts” and the depletion of beneficial microalgae in favour of harmful algal blooms.

  17. New paper from our group led by @lawojcik! We found that not only trait adaptation among but also within functional groups shape ecosystem functioning in simple food webs. Models may gain to consider multiple diversity facets and their corresponding sources of trait adaptation. Read more at doi.org/10.1111/oik.10544.
