Biodiversity on Earth Increases With Global Warming
It would seem logical that periods of global warming in Earth’s history started the extinction pulses that defined the geological record. However, that’s not the…
Generational Conflict Between Unrelated Childbearing Women Affects the Child’s Survival
Menopause affects humans, pilot whales and killer whales. These are the only organisms on Earth that stop being able to reproduce long before their lifespan…
Pacific Islanders Weapons Indicate That Three Shark Species Disappeared
The analysis of the weapons used by the indigenous people of the Gilbert Islands in the central Pacific Ocean, which primarily use shark teeth, indicate…
Genetic Analysis Reveals New Family Tree for Ray-Finned Fish
A newly published study from Yale University scientists suggests that the earliest ray-finned fishes called teleosts appeared well before what researchers had previously thought, finding…
Insects Help Scientists Understand the Predictability of Evolution
A newly published study by Cornell scientists details how they examined insect species that feed on plants containing powerful toxins called cardenolides to better under…
Marine Reserves Enhance Resilience to Climatic Impacts & Aid in Ecosystem Recovery
A new study from scientists at Stanford University and the Monterey Bay Aquarium reveals scientific evidence suggesting that marine reserves enhance resilience to climatic impacts,…
Nitrogen Pollution Is Altering Sensitive Ecosystems
Researchers at the University of Colorado Boulder believe that nitrogen emissions are altering sensitive ecosystems in the Rocky Mountain National Park, representing a first step…
Climate Change Affects Australian Shrub
While some mass media outlets are dismissing the obvious global climate change, nature isn’t. The hopbush (Dodonaea viscosa), the subspecies angustissima in South Australia, has…
Extinctions Due to Habitat Loss are Proportional to the Area Destroyed
While studying extinction threat due to habitat loss, scientists found that the relationship between geographic area and richness of species primarily depends on the mean…
Preserving Biodiversity When Agricultural Production Increases
A new study from researchers at Stanford University looks at how to preserve biodiversity while increases in agricultural production to feed people continue. To keep…
Rediscovery Sheds New Light on the Behavior of the Proboscis Anole
A team of scientists, encouraged by a handful of sightings, traveled to Mindo looking for a lizard once thought to be close to extinction –…
Fear of Predators in Grasshoppers Slows Plant Decay in Ecosystem
The fear of predators in an ecosystem can have a vast impact on soil ecology, simply due to the stress they put upon their prey….
First Direct Observation of an Under-Ice Algal Bloom in the Arctic
During a NASA-sponsored ICESCAPE expedition, scientists found a massive algal bloom under the Arctic sea ice. Once thought impossible, this marks the first direct observation…
Recreational Fishing is Causing the Collapse of Cape Cod’s Salt Marsh Ecosystems
According to a new study, ecologists at Brown University have discovered that recreational fishing has reduced predators in many of Cape Cod’s salt marsh ecosystems,…
Evidence Suggests that Earth May Be Headed Toward an Irreversible Change in the Biosphere
A new paper by 22 international scientists describes the need for better predictive models based on detailed understandings of how the biosphere reacted in the…
Insight on the Evolution of Cocaine Biosynthesis
With little known about how plants produce cocaine, biochemists at the Max Planck institute set out to better understand the process, finding that an enzyme…
