Sentences with phrase «european migratory»

The current European migratory crisis shows how politically sensitive the surveillance of the EU's external borders is and the dramatic human consequences of the failures of that surveillance.

These data show that almost all the assessed European migratory birds have advanced their spring migration over the last four decades of the 20th century.

Some studies show that birds that winter in Africa are most vulnerable, others state shorter - distance European migratory birds are most affected.

This study showed that in fact many European migratory birds do indeed advance the timing of their spring migration in response to climate change [so another study in favour of climate (temperature) over circadian rhythm for migration timing] and that it may actually be the long - distance migratory birds that show better adaption:

African - European migratory birds can offer an early climate warning Now why would a study over ten years old that looks back at the late 20th century already find such stark climate change impacts?

Comparing 100 European migratory bird species — some migrate sooner, some do not, and probably the ones that winter in Africa are most vulnerable to climate change But then of course we have to exclude the possibility that it's just a flycatcher phenomenon — there's always one that oversleeps, right?

Well, the temporal mismatch is probably a broad phenomenon, leading to various population declines among European migratory birds, although some species seem to adapt better than others.

«Our study clearly showed that European migratory bird species with declining breeding populations in Europe in the last decades (1990 — 2000) responded the least to recent climate change as reflected by the temporal trend in spring migration phenology, or even delayed their timing of spring migration, whereas species with stable or increasing populations advanced migration.»

Now ancient DNA from the fossilized skeleton of a short, dark - skinned, dark - eyed man who lived at least 36,000 years ago along the Middle Don River in Russia presents a different view: This young man had DNA from all three of those migratory groups and so was already «pure European,» says evolutionary biologist Eske Willerslev of the Natural History Museum of Denmark at the University of Copenhagen, who led the analysis.

And the Intergovernmental Panel on Climate Change, a few years ago in its fourth assessment in 2007, said to the Europeans — but it could have been to the Americans for that matter in a different context — Europeans if you care for your songbirds, as Europeans really do, look to Africa and how African habitats are doing: 84 percent of the migratory birds in the world are vulnerable to climate change.

European robins also showed constant levels of Cry4 during a 24 - hour cycle, and higher levels during their migratory season.

The researchers then went on to study the immune system in three different groups: sedentary birds in tropical Africa, European sedentary birds, and migratory birds.

«What really surprises me is that the immune systems of migratory birds show a similarly low variation to that of European sedentary birds.

It will be of interest to investigate the prevalence of the European AMPV - C in wild migratory birds further, and to test the genetic relationship with AMPV - C in the USA and HMPV.

And because the speed of European spring warming in recent decades is globally unprecedented, bird species that migrate between Africa and (West) Europe may offer an early warning for similar effects in Asian and American migratory birds.

Such approach should combine the use of intelligence at the operational / tactical level with the application, at the strategic level, of the typical methods of intelligence analysis to better understand migratory flows, routes and vulnerabilities in the system of the external borders (in this sense, see the recent Proposal on the European Border and Coast Guard, COM (2015) 671 final and its artt.
