Reference excerpt

Ivette Perfecto is an ecologist and professor at the University of Michigan. Her work focuses on complex ecosystem dynamics and the application of ecological theories to agricultural systems.

Early life and education Ivette Perfecto was born in San Juan, Puerto Rico. As a child, she was fascinated by the environment of the Caribbean. She enjoyed the outdoors, particularly the underwater world she could explore while snorkeling. The interactions she observed between organisms sparked her original interest in biology. However, the contamination of many of Puerto Rico's ecosystems that resulted from the industrialization programs of Operation Bootstrap instilled a passion in Perfecto for environmental sciences. She enrolled in the Universidad Sagrado del Corázon in Santurce, Puerto Rico and graduated with a B.S. of Biology in 1977. After earning an undergraduate degree, Perfecto was accepted as a graduate student at the University of Michigan in Ann Arbor, Michigan. At the time she was a single mother and was often unable to start her work until after she had put her son to bed in the evenings. In 1982 she earned her Masters of Ecology and then returned to Puerto Rico where she taught college biology. She taught biology for a year in Puerto Rico, but her desire to continue conducting research lead her to return to the University of Michigan where she earned a PhD in Ecology and Natural Resources in 1989.

Career and research Perfecto is a professor in the School for Environment and Sustainability at the University of Michigan and became the George W. Pack Professor of Natural Resources and Environment in 2009. Her work can be generalized under the category of ecology, but specifically she studies agroecology, diversity in coffee agricultural systems, and conservation biology. Some of her major findings have included a better understanding of complex ecosystem dynamics through the analysis of spatial factors and trait mediated effects. Perfecto's research regarding the improvement of agricultural systems through the application of ecological theories is inherently interdisciplinary. It reflects her career as a scientist and efforts as an engaged activist to improve the livelihoods of Puerto Rican agriculturists through research and communication. Her work regarding the role of pest species in agroecosystems has been utilized to the effect that the use of pesticides can be reduced to the benefit of farmers. In addition, Perfecto has researched the effect of shade trees in agroecosystems as a potential alternative to increased irrigation in the face of climatic alterations such as increased temperature and decrease precipitation. Perfecto has a large volume of published books and scientific articles. More than 100 journal publications and articles that she has authored or co-authored have been cited over 27,000 times. She is also one of the founders of Alianza de Mujeres en Agroecología-Alliance of Women in Agroecology.

Public engagement Perfecto and co-contributors, John Vandermeer and Javier Lugo, were awarded a United States Department of Agriculture-National Institute of Food and Agriculture grant in 2018 assessing the effects of Hurricane Maria on the resiliency of coffee farms in Puerto Rico. Perfecto and Vandermeer also developed a board game called "Azteca-Chess" to improve coffee farmers' understanding of the ecological complexity of their farms. The game incorporates the pests common to coffee farms and is designed to educate players about the beneficial roles these insects can have in a coffee agroecosystem. Through the dissemination of this game, farmers will better understand the interconnected nature of the ecosystems they cultivate and use this knowledge to inform decisions regarding pest management.

Worked examples

Example 1 — a first encounter with Ivette Perfecto

Start with the simplest possible case. Write down what Ivette Perfecto 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 Ivette Perfecto 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 Ivette Perfecto 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 Ivette Perfecto

In research: Ivette Perfecto 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 Ivette Perfecto 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: Ivette Perfecto is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century Puerto Rican scientists, American ecologists, American women academics, so understanding it makes those chapters shorter.
In everyday life: Look for Ivette Perfecto 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.
