As oceans warm and become more acidic and oxygen-poor, Smithsonian researchers asked how marine life on a Caribbean coral reef copes with changing conditions.
At the Smithsonian’s Bocas del Toro Research Station, in Panama, marine biologist Rachel Collin runs an educational program that recruits international experts to teach and create videos about how to collect, preserve and observe marine invertebrates, passing down their very specific knowledge to aspiring taxonomists.
Large marine animals generally have unique functions for the ecosystem. They are also more susceptible to extinction when their habitats are altered. Around 3 million years ago, at least one third of the marine megafauna became extinct, possibly due to sea level fluctuations and the contraction of coastal habitats. This also led to a loss of some of their ecological functions. In the current era, many large marine animals are deemed at risk of extinction. What will be the consequences of this potential loss?
Sharks’ bodies are covered with tiny, tooth-like scales called denticles. Shed denticles settle to the ocean floor, where they remain in sediments for years and can be used to understand which sharks lived on a reef in the past.
Most coral species fared better in the shaded environment offered by the mangrove canopy
Picture this: What to do at a party when you try to carry on a conversation, but the music is too loud? A Panamanian doctoral student is trying to figure out how dolphins communicate underwater during heavy boat traffic in the Bocas del Toro Archipelago.
The guide aims to be a clarifying, science-based framework guiding the global community in the establishment of Marine Protected Areas
Coral reefs in the Tropical Eastern Pacific (TEP) are exposed to a broad range of environmental conditions defined by the upwelling of cold, nutrient-rich water from the deep ocean. Regional variation in upwelling activity along the TEP make it an ideal natural laboratory to understand the importance of changing environmental conditions for reef health and resiliency. Watch Panamanian scientist Andrew Sellers explain the aims of the ambitious Rohr Reef Resilience (RRR) Project, and his experience in recent research expeditions to the Panamanian and Costa Rican Pacific.
Nine articles explore impacts of ancient human societies on tropical ecosystems, revealing the importance of incorporating the paleosciences, social sciences and Indigenous traditional knowledge to solve contemporary environmental challenges.
