Baby biodiversity in the ocean

'Python of the Sea' Study Highlights How Marine Biodiversity Can Be Dramatically Underestimated

Most ocean life remains to be discovered. Because fish and many other animals that live in the ocean often have larvae or other, microscopic life stages that drift freely in ocean water, counting species by genetic barcoding of plankton samples adds to counts of species recorded as adults and is a highly efficient way to understand what lives in the ocean and how biodiversity changes as we modify the ocean environment

Dedicated to “the Ancestors who stewarded the ocean” an interactive story map created by the Pacific Sea Garden Collective reawakens traditional ways of harvesting food from the sea from Panama to Australia to the Pacific Northwest.

Unique Agates on a Panamanian Island Reveal Submarine Volcanic Activity

Giant agates found in an island on Panama's Pacific coast prompted a study on how the Isthmus evolved and became a bridge between two continents

An Indigenous Language Book Presents the Unique Biodiversity of a Panamanian Island

Botanist Alicia Ibañez hopes the book, which presents new data on the tiny island’s endemic flora and fauna in both Spanish and Ngäbere, will increase awareness of the importance of preserving its biodiversity

Accidental Slingshot Wound to a Tree Reveals Unexpected Ant Behavior

Despite significant movement restrictions during the first wave of the pandemic in Panama City, a group of curious high school students roamed their neighborhood drilling holes into Cecropia trees and documenting how Azteca alfari ants responded to damage to their host plant.

As part of her fieldwork, Fernandez habituated the bats to her presence near their day-roosts, obtaining observations of their natural behaviors and recording their vocalizations in a completely undisturbed environment during months. (Ana Endara)

Similar to Human Babies, This Bat Species Learns to Communicate Through Babbling and Vocal Imitation

Long-term monitoring of the bat species Saccopteryx bilineata in their natural setting revealed that pups display babbling behavior strikingly similar to that of human infants

Many terrestrial birds disappeared in Barro Colorado Island, in the Panama Canal, despite their abundance in adjacent mainland forests, because they could not cross Gatun Lake to maintain populations on the island. (Ghislain Rompre)

Biodiversity Loss Despite a Century of Protection

The Barro Colorado bird community has lost about a quarter of its species over time

From the surface, the havoc caused on a coral reef by a layer of low-oxygen water was barely evident.

Watch What Happens When A Coral Reef Can't Get Enough Oxygen

In September, 2017, divers observed a massive 'dead zone' rising to envelop Caribbean coral reefs in Bocas del Toro, Panama. Smithsonian post-docs formed a team to understand why reef animals were fleeing, and the role of humans in the history of hypoxia.

Heather Stewart, former PhD fellow at STRI, is very involved in local and global initiatives related to the conservation of coastal ecosystems in the Caribbean, such as mangrove forests.

The cloud forests in the Fortuna Hydrological Reserve are home to almost as many species as the entire United States.

The Fortuna Hydrological Reserve hosts one third of Panama’s tree species, a variety of fungi waiting to be discovered and a great potential to offset global warming

From Refuge Cove in Alaska to San Francisco Bay to Baja California and at the Pacific entrance to the Panama Canal, a team from the Smithsonian Tropical Research Institute and Temple University deployed panels to find out what limits marine invertebrate invasions. Here, Laura Jurgens and Carmen Schloeder, celebrate a successful deployment in Mexico (Laura Jurgens)

Invasion Dynamics

Smithsonian marine biologists and colleagues at Temple University tested predictions about biological invasions, first in Panama and then in an experiment of unprecedented geographic scale.

Ana K. Spalding and 23 other women scientists from around the world, advocate for a shift in the value system in science, to emphasize a more equal, diverse and inclusive academic culture.

Women in Science Propose Changes to Discriminatory Measures of Scientific Success

The scientists advocate shifting the current value system, which is biased against women and minorities, towards a more diverse and inclusive model of science

In her lab at the Smithsonian Tropical Research Institute, Annette Aiello usually rears caterpillars to find out which butterflies they become as adults, but in this case, she focused her attention on cicadas emerging from a houseplant on her porch in Arraijan, Panama. (J. Aleman/STRI)

Like A Cooking Show With Worms: Smithsonian Videos Teach Tropical Taxonomy of Diverse Marine Creatures

A program at the Smithsonian’s Bocas del Toro Research Station, in Panama, allows marine invertebrate experts to pass down their very specific knowledge to aspiring taxonomists.

The purple-flowered crown of Dipteryx oleifera, one of the biggest trees on Barro Colorado Island, Panama, towers above the forest. Big trees may be most exposed to the effects of climate change: more frequent and severe drought, and the high winds and lightning of monster storms. (Evan Gora)

How Will the Biggest Tropical Trees Respond to Climate Change?

The death of these giants would have a major impact on the forest, but because they are few and far between, almost nothing is known about what causes them to die
