In the late 1980s, something began to go wrong in places that were supposed to be safe. Protected cloud forests, buffered from chainsaws and bulldozers, started losing animals that had persisted through far rougher times. Amphibians—often abundant, often overlooked—were vanishing in ways that did not fit familiar explanations. Field biologists, trained to distrust drama, found themselves comparing notes with growing unease.
“A bunch of us got together and started comparing notes,” recalled Jay M. Savage, then a professor of biology at the University of Miami, in a 1992 interview with the New York Times. “People were struck by the fact it seemed to be occurring on a worldwide basis.” He had the standing to say so. For decades, Savage had worked at the seam where taxonomy meets ecology, building arguments from specimens, notebooks, and repeated returns to the same humid places. His specialty was amphibians and reptiles, particularly in Central America, a region he came to know through sustained fieldwork rather than brief expeditions.
One of those projects produced an animal that later became emblematic. In 1964, in what is now the Monteverde Cloud Forest Reserve in Costa Rica, Savage and a colleague documented a toad whose coloration bordered on the improbable. Its scientific name was Bufo periglenes. It was better known as the golden toad, the male a vivid orange. The species spent most of its life underground, emerging briefly each year for an explosive breeding season. Thousands once gathered. In 1988, only one adult male was found. Two years later there were none, and none have been seen since.
The pattern repeated itself. Glass frogs and harlequin frogs, once common in the same forests, declined sharply. “Human beings are great at rationalization,” Savage said. “We said, it must be local damage; if we just went over the hill, we’d find them.” What unsettled him was not the loss of any single species, but the breadth of the phenomenon.
Savage’s instinct for connecting the particular with the general had been shaped long before amphibian declines entered public debate. Trained in a mid-century scientific culture that valued collections and close description, he carried those habits into field biology and teaching. Over a long career he published extensively and trained generations of students, helping to shape herpetology as both a discipline and a community.
He was also drawn to institution-building. In the early 1960s, tropical biology was rich in promise but poor in infrastructure. Savage helped design programs that brought scientists to the tropics not as visitors but as participants, an effort that led to the creation of the Organization for Tropical Studies. It became a durable base for tropical research and training, emphasizing continuity over spectacle.
The same instincts—patience, suspicion of easy narratives, attention to what endures—shaped how Savage understood loss. He did not treat extinction as spectacle. He treated it as data with consequences.
In science, as in ecosystems, the most consequential changes are often registered first by those who return often enough to notice what is missing.
