Coral reefs, the vibrant ecosystems that support roughly a quarter of marine life, are experiencing a period of unparalleled stress. Spanning less than 1% of the ocean floor, coral reefs are found in over 100 countries and territories, playing an essential role in coastal protection, food security, and the global carbon cycle. Yet, in recent [Continue reading]
On May 22—the International Day for Biological Diversity—conservationists, scientists, and governments alike reflect on the staggering variety of life on Earth and the urgent need to protect it. Biodiversity, broadly defined, refers to the variety and variability of life at all levels: ecosystems, species, and genetic diversity within species. It underpins everything from food systems [Continue reading]
Today, May 22, is the International Day for Biological Diversity. To mark the occasion, here’s a look at the world’s most biodiverse countries and territories, using two approaches: (1) total number of species (2) species richness relative to land or marine area These rankings are always contentious. People are often disappointed or upset when a [Continue reading]
Few creatures better embody the notion of peaceful coexistence than the manatee. Slow-moving and largely indifferent to human affairs, these aquatic herbivores graze on seagrasses and algae in the shallow coastal waters of the Americas and West Africa. Yet despite their unassuming nature, manatees are increasingly at the mercy of human activity. The West Indian [Continue reading]
Few ecosystems punch above their weight quite like seagrass meadows. These humble underwater pastures, spanning over 300,000 square kilometers across six continents, quietly perform a remarkable array of ecological services. They stabilize shorelines, shelter marine life, and sequester carbon at rates up to 40 times greater than terrestrial forests. Yet, like so many unsung heroes [Continue reading]
February 16th is World Whale Day. One little-known but interesting fact about whales is that some species have been found to store carbon in their bodies for over a century, making them natural climate allies. How does that work? When whales die and sink to the ocean floor, their massive bodies trap carbon that [Continue reading]
February 15th is World Pangolin Day Among the world’s lesser-known mammals, few are as peculiar or as imperiled as the pangolin. Scaly yet soft-footed, reclusive yet trafficked in vast numbers, pangolins embody paradoxes. On World Pangolin Day, here are a few facts about these creatures that warrant more attention than they receive. 💪 The only [Continue reading]
February 14th is known for love and affection—but not only among humans. It is also World Bonobo Day, a celebration of one of our closest relatives, the endangered bonobo (Pan paniscus). These apes have long been associated with cooperation and social harmony, a reputation that aligns fittingly with Valentine’s Day. Yet, recent research paints a [Continue reading]
Today is International Zebra Day With their iconic black-and-white stripes, zebras are widely recognized, yet they are often underestimated beyond their striking appearance. Members of the horse family, zebras possess exceptional hearing and eyesight, can sprint up to 70 km/h (43 mph), and deliver kicks powerful enough to deter apex predators. Their distinctive stripes, however, [Continue reading]
Today is Wildlife Conservation Day Nature documentaries and conservation campaigns paint an image of Earth teeming with wildlife, but the numbers tell a different story. A February 2023 study, published in PNAS, quantified the biomass of the world’s mammals and revealed an ecosystem heavily dominated by humanity and its livestock. A few striking figures from [Continue reading]
Today is International Jaguar Day 🐆 International Jaguar Day is dedicated to a predator whose presence shapes forests, rivers, and plains from northern Mexico to Argentina. The jaguar, Panthera onca, is a creature of paradox: elusive yet emblematic, ferocious yet vulnerable. As the Americas’ largest big cat, its muscular frame and distinctive rosette-patterned coat symbolize [Continue reading]
Today is World Lemur Day Lemurs, Madagascar’s iconic residents, encompass over 100 species. Exclusively endemic to the island (one species was introduced to a neighboring island), these fascinating creatures have evolved into one of the most diverse primate groups on the planet. To celebrate World Lemur Day, here are five lesser-known facts about these remarkable [Continue reading]
With United Nations Biodiversity Conference (COP 16) starting today in Cali, I thought a fitting way to mark Reptile Appreciation Day would be to highlight the blue anole (https://mongabay.cc/4Ycrmm), endemic to the island of Gorgona, located off the Pacific coast of Colombia, not far from Cali. Gorgona, long noted for its biodiversity, hosts this vibrant [Continue reading]
Today is International Sloth Day 🦥 Sloths, as a group, might be said to epitomize the concept of taking life slowly. The six species, found mainly in Central and South America, spend most of their days hanging from trees, moving deliberately to conserve energy—a strategy shaped by a diet of nutrient-poor leaves. Yet, contrary to [Continue reading]
Once formidable predators in the world’s coastal and estuarine waters, sawfish—members of the ray family with their distinctive, toothed “saws”—now find themselves on the verge of vanishing. On International Sawfish Day, it is worth highlighting a creature whose form is as memorable as its fate is precarious. Sawfish, which can grow up to 7.6 meters [Continue reading]
On World Octopus Day 🐙, it seems fitting to reflect on a creature whose intelligence is as intriguing as its ability to blend into its surroundings. The octopus, a soft-bodied mollusc with eight limbs, has long mesmerized audiences ranging from scientists and storytellers. With over 300 species scattered across the oceans—from shallow coral reefs to [Continue reading]
