A new study has confirmed what biologists have long suspected: that tropical birds are much more colorful than their temperate peers.
Research led by the University of Southampton has revealed that an abrupt change in climate conditions in the North Atlantic around 800 years ago played a role in a decline in Atlantic salmon populations returning to rivers. Subsequent human exploitation of salmon combined to reduce their popula ...
New research is examining the impact of climate change on migratory Atlantic salmon. Scientists in Scotland and Canada are working on the study
Flying over Antarctica, it's hard to see what all the fuss is about. Like a gigantic wedding cake, the frosting of snow on top of the world's largest ice sheet looks smooth and unblemished, beautiful and perfectly white. Little swirls of snow dunes cover the surface.
About 20 years ago, Bala Chaudhary worked in conservation and habitat restoration in California. Her job was to design plans for creating new habitats for endangered species out of degraded or disturbed land. In her work, she kept coming up against one persistent challenge—reinstating soil micro ...
Resource pulses, i.e., occasional episodes of ephemeral resource superabundance, represent a fundamental mechanism by which energy, nutrients, and biomass are transported across ecotones. They are widespread in extant ecosystems; however, little is known about their deep-time record.
Researchers from the Xishuangbanna Tropical Botanical Garden (XTBG) of the Chinese Academy of Sciences have collected and maintained a collection of about 100 plants of Annonaceae, a large pantropical flowering plant family.
A new study led by Florida Tech recommends rewilding an island in the Galapagos with tortoises and rare plants to recreate an ecosystem irreparably damaged by whalers.
Even small differences in how fast animals grow during development can sum up to large differences in their adult body size. Nevertheless, adults of the same species are usually nearly identical in size.
Like ants, termites and bees, some bacteria work together as a multicellular group. There is a strict division of labor in such colonies, to make the group more resilient to the outside world.
Animal borne cameras now give scientists unprecedented access into the visual world of animals, including the life and death struggles of hunters and their prey.
Geckos lived in Europe as early as 47 million years ago, say paleontologists who have examined a nearly complete fossil gecko skull from central Germany. This previously unknown species was found in a former coalmining area—Geiseltal—and was described by a research team led by Dr. Andrea Villa o ...
One group of termites are habitual seafarers, suggests new research. The wood-munching insects crossed the world’s oceans at least 40 times over the past few tens of millions of years. The termites probably set sail accidentally, rafting inside pieces of wood washed out to sea.
The 2022 Atlantic hurricane season has officially started, and NASA scientists are working with partners at NOAA, FEMA and other organizations to help communities prepare for these storms and respond to their aftermath.
Electric organs help electric fish, such as the electric eel, do all sorts of amazing things: They send and receive signals that are akin to bird songs, helping them to recognize other electric fish by species, sex and even individual.
Scientists have come up with a new classification scheme for mountain belts that uses just a single number to describe whether the elevation of the mountain belt is controlled mainly by weathering and erosion or by properties of the Earth's crust, i.e., the lithospheric strength: the "Beaumont n ...
Nothing drives hurricane experts crazier than the sentiment, "Oh, it's just a Category 1." It's not just an annoying attitude, it's a deadly one. Hardly a hurricane season goes by without a fresh example of a low-category storm causing more trouble than people expected.
Extant studies have noted that China's ability to peak carbon emissions by 2030 has something to do with the economic growth rate and suggested a slowdown in economic growth in China to help peak carbon emissions. However, none of them gives a quantitative account for such a relationship.
A Kobe University research group has shed light on how low-frequency tectonic tremors occur; these findings will contribute towards better predictions of future megathrust earthquakes.
The United States has set an ambitious goal to reduce greenhouse gas (GHG) emissions by at least 50% by 2030. Are we on track to succeed?
Flies, mosquitoes, dust and even microplastics—spider webs capture whatever travels through the air. Researchers at the university have now for the first time tested if they can get an overview of plastic particles in the air by examining the eight-legged creatures' catch.
Because environmental justice screening tools will affect community members impacted by disproportionate environmental burdens, soliciting input from the environmental justice community is crucial to developing and using screening tools, according to a new study from the University of Michigan.
Earth Change Observation Laboratory, a research group operating at the Taita Research Station in Kenya and on Kumpula Campus in Helsinki, investigates environmental change with the help of field surveys and remote sensing datasets.
Comfortable urban public spaces play an important role in shaping healthy behaviors and raising well-being among citizens. Given the context of climate change, unplanned urbanization, and the worldwide air-borne pandemic, there is prominent concern about comfort in urban planning and municipal p ...
A new capability to identify urban neighborhoods, down to the block and building level, that are most vulnerable to climate change could help ensure that mitigation and resilience programs reach the people who need them the most.
Fossils of a strange early giraffoid have revealed the key driving forces in giraffe evolution, according to a study led by researchers from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences.
Analysis of long-term monitoring data for almost 1,500 species in Finland shows that four decades of climate change has led species to shift between the "better" and "worse" parts of their climatic niches, and that these impacts were most pronounced at higher latitudes.
Giant kelp forests around the world have struggled to stay healthy in recent decades, with some vanishing altogether. But along Patagonia's rugged southwestern coast, giant kelp are thriving, showing remarkable stability for almost 200 years. New research suggests frequent marine cold spells cou ...
Globally rising temperatures and the browning of lakes, i.e. changing color due to increased dissolved organic material, can both inhibit and promote algal growth in northern lakes. This is shown by Isolde Callisto Puts in her thesis that she defends on Friday 3 June at Umeå University in Sweden.
Warm, wet weather conditions and changing climate negatively influence the nectar intake and nutritional health of honey bees, but maintaining large tracts of grassy natural habitat with flowering plants around apiaries may help to mitigate the detrimental effects of climate, according to a new ...
Although bumblebees and honeybees get all the attention, other bees are just as important to a thriving ecosystem. According to recent research, pollinator diversity is far more important than the bees that are frequently in the spotlight.
The global scientific community has issued another warning that increasing climate change and biodiversity loss will together reinforce negative impacts on people around the world, including food insecurity, health risks and disrupted livelihoods, as well as involuntary displacements leading to ...
New research led by scientists at the Milner Centre for Evolution at the University of Bath suggests that determining evolutionary trees of organisms by comparing anatomy rather than gene sequences is misleading.
A lava lake in a crater of Kīlauea spent ten years sloshing and churning before the volcano gave a bigger belch. Kīlauea erupted dramatically in 2018. Earthquakes, ash plumes, and lava flows disrupted life on Hawaii's Big Island and changed the volcano's topography.
An ancient bout of global warming 56 million years ago that acidified oceans and wiped-out marine life had a milder effect in the Gulf of Mexico, where life was sheltered by the basin's unique geology—according to research by the University of Texas Institute for Geophysics (UTIG).
Though Africa is home to the second largest collection of biodiversity on earth, many of its unique plants, animals and microbes are facing extinction due to human activities and climate change.
A prehistoric food fight may have spelled the end for the megalodon, the largest shark that ever lived. A study of the ocean giant's fossil teeth suggests it had to compete for food with another ferocious predator, the great white shark.
The Blue Mountains of Jamaica are frequently covered in a dense blanket of cloud, but when it lifts the first thing you notice is the cloak of forest extending up their steep slopes to the top of the highest peaks.
The Tibetan Plateau (TP) is referred to as the "water tower" of Asia for being home to the headwaters of many major rivers in Asia, including the Yangtze, Yellow, Ganges, and Indus. Therefore, TP precipitation is important for not only local, but regional water resources too.
Government coalitions often dissolve when too many parties disagree on too many issues. Even if a coalition seems stable for some time, a small crisis can cause a chain reaction that eventually causes the system to collapse.
Scientists have described the youngest therizinosaur fossil from Japan and the first in Asia to have been found in marine sediments Therizinosaurs were a large group of primarily herbivorous theropod dinosaurs (dinosaurs with hollow bones and three-toed limbs). .
A new study published in Current Biology suggests that the European cuttlefish (sepia officinalis) may combine, as necessary, two distinct neural systems that process specific visual features from its local environment and visual cues relating to its overall background environment to create the ...
Around 6,000 years ago, more than two-thirds of Europe was covered in forest, a 2018 study found. But because of land clearing for agriculture and the use of wood for fuel, that number has more than halved, and today only around one third of Europe is woodland. In some countries like the UK and ...
Deborah Giles would know. As the research director of the nonprofit Wild Orca and a research scientist at the University of Washington, Giles has worked for years on a project collecting scat from endangered Southern Resident killer whales to better understand their health.
We hear a lot about how climate change will change the land, sea, and ice. But how will it affect clouds? "Low clouds could dry up and shrink like the ice sheets," says Michael Pritchard, professor of Earth System science at UC Irvine. "Or they could thicken and become more reflective."
Animals possess circadian clocks, or 24-hour oscillators, to regulate daily behavior. These typically take their cues from the periodic change of sunlight and darkness. However, many animals are also exposed to moonlight, which reoccurs with ~25h periodicity.
Researchers were stunned when they discovered a species of seagrass had effectively cloned itself for 4,500 years and covered nearly 80 square miles.
Some male wolf spiders seem to get luckier than others when it comes to courting females. The secret of their courtship? It's complicated, says a new study led by the University of Nebraska–Lincoln.
DNA "fingerprints" left behind by sea turtles offer scientists a simple, powerful way of tracking the health and whereabouts of these endangered animals, a key step forward in their conservation.
The term biodiversity invites images of lush rainforests, dynamic estuaries, and other biomes where a kaleidoscope of species interact within their communities. We could assume the same holds true for biodiversity at the microscopic level.
