The House Judiciary Committee is marking up immigration provisions today as part of the budget reconciliation process. Stephen Yale-Loehr, professor of immigration law at Cornell Law School and co-author of a leading 21-volume immigration law series, says that Democrats face an…
Each year, many shark species migrate hundreds of miles, traversing ocean waters to return to the same spot year after year. Now, Florida State University researchers have found that sharks likely use the Earth’s magnetic fields to help guide them on these long-distance journeys.
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…
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.
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.
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…
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.
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.
According to a new study, environmental hazards affect populations worldwide and can drive migration under specific conditions, especially in middle-income and agricultural countries.
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.
Researchers at the University of Chicago found that some commercially-bred monarch butterflies appear to be capable of migrating south, while wild-derived monarch butterflies raised in a closed greenhouse are worse at migrating south than their outdoor-raised counterparts.
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.
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.
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 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.
Migratory birds are now flooding across the continent, as they return to their nesting grounds this spring. World Migratory Bird Day is on May 9, 2020, as people around the globe welcome birds back—and lend them a helping hand.
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.
Lights Out Texas is a new two-year study now underway in Houston, Dallas, and Fort Worth. Along with local partners, researchers from the Cornell Lab of Ornithology and Colorado State University plan to test the best times to turn off lights at night in order to prevent harm to the hundreds of millions of birds migrating over these cities.
New IIASA research shows that higher levels of education and increasing workforce participation in both migrant and local populations are needed to compensate for the negative economic impacts of aging populations in EU countries.
The eBird program at the Cornell Lab of Ornithology just released more than 500 animated maps spanning the entire Western Hemisphere. The maps show in fine detail where hundreds of species of migratory birds travel and how their numbers vary with habitat, geography, and time of year.
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.
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.
Fear of the virus may spread faster than the virus itself, a potential threat to health, liberty, trade, and the economy.
A mix of factors is involved in Chicago’s declining black population and others aren’t well defined, but inequality stands out as a leading element, according to a new report from the Institute for Research on Race and Public Policy at the University of Illinois at Chicago.
“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.
The Council on Foreign Relations (CFR) introduces Think Global Health, a multi-contributor website that examines how changes in health are reshaping economies, societies, and the everyday lives of people around the world.
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.
