Reference excerpt

Stéphanie Jenouvrier is a French population ecologist with a research interest in Antarctic seabirds as indicators of climate change. She is currently a senior scientist leading the Forecasting the Long term Ecological and Demographic impacts of Global Environmental changes (FLEDGE) lab at the Woods Hole Oceanographic Institution (WHOI). She is most known for her work with emperor penguin population forecasting models, where she reported massive declines for the species by the end of the century based on several factors including sea-ice loss.

Education Jenouvrier obtained her Bachelor of Science degree in Biology and Ecology from the University of Paris-Sud in 1999. During her time there, Jenouvrier studied brown bears in Pyrénées National Park, France, where she worked on a statistical monitoring and tracking program for the population. In 2001, Jenouvrier obtained a master's degree in ecology from the University of Pierre et Marie Curie in Paris, where she studied the performance of a statistical model in biodiveristy dynamics, as well as golden eagle conservation in Mercantour National Park. Her education terminated in 2004 with a PhD in Population Ecology from the same university. Jenouvrier's dissertation was on southern fulmar population dynamics, published in the British Ecological Society's Journal of Animal Ecology. Jenouvrier then went on to complete a postdoctoral project at the Center for Biological Studies of Chizé

Career and impact Jenouvrier's research uses models to understand and predict seabird population dynamics amidst a changing climate, as seabirds are known to be good indicator species of climate change. In 2009, Jenouvrier linked climate models with models of penguin biology to determine the response of penguins to a changing climate. Her subsequent work revealed that Emperor penguins will be quasi-extinct by the year 2100 if warming as a result of carbon emissions continues on its current predicted path. This is due to loss in sea ice, which is important for emperor penguin breeding, molting, and feeding practices. Jenouvrier's study on emperor penguins has been highlighted in several articles and a short film. It was one of the driving forces in updating the species' to "threatened status" under the Endangered Species Act in 2022. Jenouvrier is also a part of Project SENSEI (Sentinels of the Sea Ice), a French effort to understand and educate about the impacts of changing sea ice through indicator species. Through this program Jenouvrier has produced scientific work on southern fulmars in the Southern Hemisphere and has contributed to the goal of outreach through video lectures and other educational material.

Awards and honors In 2006, Jenouvrier received a L'Oréal-UNESCO For Women in Science Award.

Worked examples

Example 1 — a first encounter with Stephanie Jenouvrier

Start with the simplest possible case. Write down what Stephanie Jenouvrier claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Stephanie Jenouvrier before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Stephanie Jenouvrier ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Stephanie Jenouvrier

In research: Stephanie Jenouvrier appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Stephanie Jenouvrier in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Stephanie Jenouvrier is common in secondary-school and first-year university syllabi. It links to neighbouring topics French ecologists, French women scientists, L'Oréal-UNESCO Awards for Women in Science laureates, so understanding it makes those chapters shorter.
In everyday life: Look for Stephanie Jenouvrier outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
