Flowers are known for their beauty, color, and fragrance—but did you know that some can generate heat like warm-blooded animals? That’s right. A few rare plants use metabolic heat , a phenomenon called thermogenesis , to melt snow, spread their scent, and attract pollinators. Among them, the star performer is the skunk cabbage . What Is Thermogenesis in Plants? Thermogenesis is the ability of some plants to produce internal heat by burning energy (like animals do). Unlike most plants, which are cold-blooded in the sense that they match the temperature of their environment, thermogenic plants can warm themselves up —sometimes by more than 20°C above the surrounding air. This rare trait is mostly seen in early-blooming or tropical plants that need to attract pollinators under challenging conditions. Meet the Skunk Cabbage: Nature’s Floral Furnace One of the best-known thermogenic plants is the Eastern skunk cabbage (Symplocarpus foetidus) , which grows in wetlands and forests of ...

 Imagine a floating island in the middle of the ocean, not made of sand or rock, but of plastic waste. This isn't science fiction. It's the reality of what we now call "Plastic Island" or more technically, the Great Pacific Garbage Patch. These vast accumulations of plastic debris are not only unsightly but represent one of the most pressing environmental issues of our time. What is Plastic Island? Plastic Island refers to large areas in the ocean where plastic and other debris accumulate due to ocean currents. The most infamous is the Great Pacific Garbage Patch, located between Hawaii and California. This patch covers an area estimated to be 1.6 million square kilometers and contains around 1.8 trillion pieces of plastic. How Does It Form? The formation of Plastic Island is largely due to a combination of human negligence and natural oceanic processes. Plastics from land-based sources (like littering and poor waste management) and ocean-based sources (such as fishi...

W hen ecologists measure biodiversity, they often focus on the species that are present in an ecosystem. But what about the species that are missing , even though the conditions are right for them to exist there? This concept is known as "dark diversity" —the invisible counterpart to observed biodiversity. It's a new frontier in ecological research that could transform how we understand ecosystems, restoration, and conservation. What Is Dark Diversity? Dark diversity refers to the set of species that are ecologically suitable to live in a given habitat but are currently absent . These are not extinct species, nor are they exotic invaders. They are potential native species that could be part of the community but are not—often due to historical disturbances, dispersal limitations, or human impact. It’s similar to the idea of dark matter in physics: unseen, but influential. Key Concepts Species Pool : The total set of species that could inhabit a given area based on...
