Scenarios for proactive measures and inclusive policies on migration in Europe

Migration is a complex and unpredictable phenomenon, often triggered by political crises, economic downturns, and natural or human-made disasters. A new policy brief and a White Paper authored by IIASA researchers and UK colleagues provides valuable insights and recommendations to support policymaking and increase understanding around the realistic implications of high-migration events.

Corridors between Western U.S. national parks would greatly increase the persistence time of mammals

A new study analyzed the value of establishing ecological corridors for large mammals between Yellowstone and Glacier National Parks and between Mount Rainier and North Cascades National Parks. These corridors would enlarge populations and species to shift their geographic ranges more readily in response to climate change.

Fossil CSI: Analysis of giant extinct marine reptile graveyard suggests mysterious site was ancient birthing grounds

Marine giants make migrations across the ocean to give birth where predators are scarce, congregating annually along the same stretches of coastline. A study suggests that 200 million years before whales evolved, school bus-sized marine reptiles called ichthyosaurs may have made similar migrations.

Modeling Study Projects 21st Century Droughts Will Increase Human Migration

Drought and the potential increase in the number of droughts worldwide due to climate change remains a concern for scientists. A recent study led by Stony Brook University researchers suggests that human migration due to droughts will increase by at least 200 percent as we move through the 21st Century.

Does environmental stress drive migration?

While climate-driven migration has been deemed a major threat in public discourse and academic research, comprehensive studies that take into account both environmental and social factors globally have been scarce. Now, with the help of machine learning, a research team led by Aalto University has drawn a clearer picture of the factors involved in migration for 178 countries.

Another threat from the climate crisis: Violent conflicts, including genocide, will worsen as countries compete for dwindling resources

Throughout all of human history, natural resources have been a flashpoint for conflict. As worsening climate change puts those resources at increasing risk through the rise in sea levels, more frequent flooding and the loss of arable land and clean…

Despite refugee boost and family reunification, Biden has ‘long road to go’

On Monday, the Biden administration announced a significant increase in the number refugees allowed to enter the United States. The announcement comes as the administration also begins to reunite parents separated from their children under the Trump administration’s family separation…

Deep dive into bioarchaeological data reveals Mediterranean migration trends over 8,000 years

A team of international researchers led by a Florida State University assistant professor has analyzed reams of data from the Neolithic to Late Roman period looking at migration patterns across the Mediterranean and found that despite evidence of cultural connections, there’s little evidence of massive migration across the region.

Fishes Contribute Roughly 1.65 Billion Tons of Carbon in Feces and Other Matter Annually

Scientists have little understanding of the role fishes play in the global carbon cycle linked to climate change, but a Rutgers-led study found that carbon in feces, respiration and other excretions from fishes – roughly 1.65 billion tons annually – make up about 16 percent of the total carbon that sinks below the ocean’s upper layers.

Biden’s attention to immigration ‘root causes’ promising, but will take time

The Biden administration’s executive orders on immigration announced this week will address Trump-era immigration policies including the controversial Migrant Protection Protocol, known as “Remain in Mexico,” and the family separation policy. Ian Kysel, professor of law at Cornell University and…

Less Light, More Trees Assist Migrating Birds

Scientists from the Cornell Lab of Ornithology and Colorado State University used observations from the Lab’s eBird citizen-science program to estimate the seasonal species richness of nocturnally migrating passerines within 333 well surveyed urban areas in the contiguous U.S. “Richness” is defined as the number of different species in an area.

Join Online Events to Celebrate Bird Migration

Day and night, across the country right now, a river of migrating birds is flowing overhead. The Cornell Lab of Ornithology holds its Migration Celebration to take note of this remarkable natural phenomenon. This year, Migration Celebration is taking place virtually with two weeks of special online events, including articles, activities, and live events.

New study on migration success reinforces need for monarch butterfly milkweed habitat

A recently published study presents evidence that the migration success of monarchs hasn’t declined in recent years and thus cannot explain the steep decline in the monarch population over the last few decades. The study drew on data collected on 1.4 million monarch butterflies that were tagged in the United States Midwest from 1998 to 2015 and emphasizes the need for new monarch habitat.

Climate change-influenced refugee crisis may lead to long-term settlement issues

While many models suggest that climate change will prompt a substantial number of people to leave their homes, not all research so clearly finds this is the case. Investigating cases where computer models seemed to indicate only limited impacts of climate change on people leaving rural areas, a team of researchers now suggest that the models may reveal a more nuanced circular migration pattern in areas stricken by climate change impacts.

Study First to Show Tiger Sharks’ Travels and Desired Hangouts in the Gulf of Mexico

Using sophisticated satellite telemetry, a study is the first to provide unique insights into how tiger sharks move and use habitats in the Gulf of Mexico across life-stages. Data provide an important baseline for comparison against, and/or predicting their vulnerability to future environmental change such as climate variability or oil spills.

Rutgers Expert Can Discuss Family’s 43-Year Backyard Bird Citizen Science Project

New Brunswick, N.J. (June 8, 2020) – Rutgers University–New Brunswick Professor Kimberly Russell is available for interviews on an upstate New York family’s 43-year family tradition – a competition to predict the arrival of American robins in their backyard every spring…

Oyster Farming and Shorebirds Likely Can Coexist

Oyster farming as currently practiced along the Delaware Bayshore does not significantly impact four shorebirds, including the federally threatened red knot, which migrates thousands of miles from Chile annually, according to a Rutgers-led study. The findings, published in the journal Ecosphere, likely apply to other areas around the country including the West Coast and Gulf Coast, where oyster aquaculture is expanding, according to Rutgers experts who say the study can play a key role in identifying and resolving potential conflict between the oyster aquaculture industry and red knot conservation groups.

Birds Are Coming Through: Time to Switch Off the Lights

The biggest window of opportunity is opening up now to protect birds returning to the United States and Canada on their spring migrations. Analyses by scientists at the Cornell Lab of Ornithology and Colorado State University pinpoint key periods with the heaviest movements of birds in April and May. Turning off or reducing non-essential lighting at homes, businesses, and high-rise buildings will help protect hundreds of millions of birds migrating over brightly lit cities.

Each Mediterranean island has its own genetic pattern

A Team around Anthropologist Ron Pinhasi from the University of Vienna – together with researchers from the University of Florence and Harvard University – found out that prehistoric migration from Africa, Asia and Europe to the Mediterranean islands took place long before the era of the Mediterranean seafaring civilizations.

Earliest interbreeding event between ancient human populations discovered

The study documented the earliest known interbreeding event between ancient human populations— a group known as the “super-archaics” in Eurasia interbred with a Neanderthal-Denisovan ancestor about 700,000 years ago. The event was between two populations more distantly related than any other recorded.

Major Asian Gene Study to Help Doctors Battle Disease

“Under-representation of Asian populations in genetic studies has meant that medical relevance for more than half of the human population is reduced,” one researcher said.

Ancient Rome: a 12,000-year history of genetic flux, migrations and diversity

Scholars have been all over Rome for hundreds of years, but it still holds some secrets – for instance, relatively little is known about where the city’s denizens actually came from. Now, an international team led by Researchers from the University of Vienna, Stanford University and Sapienza University of Rome, is filling in the gaps with a genetic history that shows just how much the Eternal City’s populace mirrored its sometimes tumultuous history.
