Psychologists know that childhood trauma, or the experience of harmful or adverse events, can have lasting repercussions on the health and well-being of people well into adulthood. But while the consequences of early adversity have been well researched in humans, people aren’t the only ones who can experience adversity. If you have a rescue dog, you probably have witnessed how the abuse or neglect it may have experienced earlier in life now influence its behavior – these pets tend to be more skittish or reactive. Wild animals also experience adversity. Although their negative experiences are easy to dismiss as part of life in the wild, they still have lifelong repercussions – just like traumatic events in people and pets. As behavioral ecologists, we are interested in how adverse experiences early in life can affect animals’ behavior, including the kinds of decisions they make and the way they interact with the world around them. In other words, we want...

Two-thirds of the world’s food comes today from just nine plants: sugar cane, maize (corn), rice, wheat, potatoes, soybeans, oil-palm fruit, sugar beet and cassava. In the past, farmers grew tens of thousands of crop varieties around the world. This biodiversity protected agriculture from crop losses caused by plant diseases and climate change. Today, seed banks around the world are doing much of the work of saving crop varieties that could be essential resources under future growing conditions. The Svalbard Global Seed Vault in Norway supports them all. It is the world’s most famous backup site for seeds that are more precious than data. Tens of thousands of new seeds from around the world arrived at the seed vault on Svalbard, a Norwegian archipelago in the Arctic Ocean, in mid-October 2024. This was one of the largest deposits in the vault’s 16-year history. And on Oct. 31, crop scientists Cary Fowler and Geoffrey Hawtin, who played key roles in creating t...

The gentle, slow-moving Florida manatee has no natural predators. And yet, these charismatic mammals face numerous threats. Manatees are struck by vessels in busy waterways across the state, and a majority bear scars from these collisions. Harmful algal blooms – characterized by the rapid growth of algae that degrades water quality – can impair their nervous systems. With less blubber, or fat, compared with other marine mammals like whales, dolphins, seals and sea lions, manatees are vulnerable to cold-stress syndrome during winter months. And they can ingest or get entangled in marine debris like derelict fishing gear and drown or be crushed by floodgate and water control structures. I am a doctoral candidate in marine biology at Florida International University’s Institute of Environment. Over the past 15 years, I have gained extensive experience working with marine mammals, particularly manatees. Recently, my colleagues at the United States Geologi...
