Global trends show seabird populations dropped 70 per cent since 1950s

Media Release | July 9, 2015

UBC research shows world’s monitored seabird populations have dropped 70 per cent since the 1950s, a stark indication that marine ecosystems are not doing well.



Michelle Paleczny, a UBC master’s student and researcher with the Sea Around Us project, and co-authors compiled information on more than 500 seabird populations from around the world, representing 19 per cent of the global seabird population. They found overall populations had declined by 69.6 per cent, equivalent to a loss of about 230 million birds in 60 years.

“Seabirds are particularly good indicators of the health of marine ecosystems,” said Paleczny. ”When we see this magnitude of seabird decline, we can see there is something wrong with marine ecosystems. It gives us an idea of the overall impact we’re having.”

The dramatic decline is caused by a variety of factors including overfishing of the fish seabirds rely on for food, birds getting tangled in fishing gear, plastic and oil pollution, introduction of non-native predators to seabird colonies, destruction and changes to seabird habitat, and environmental and ecological changes caused by climate change.

Damn, life is dying all around us but yet it isn't happening within the minds of some. damn.
 
This is an ecological study that needs to be done. Maybe -- specie by specie. Take $$1/2Bill from the GW budget and do it. And clean up the floating garbage dumps in the ocean.. You could build 3rd world INDUSTRIES around doing just that..

The Warmers have not only hijacked the entire list of ECO causes -- but their mindless minions don't even RECOGNIZE what ecology and conservation are about anymore. They are the walking brainwashed.
 
What'd I miss? Are the birds dying because they need to die? Is it just natural variation? Noise in the bird population numbers? Are they actually all in bird cages somewhere we just don't know about? Did they all just fly away? What? What?
 
From the paper itself:
We constructed a global database of available primarily English-language seabird population size records worldwide for the years spanning 1950–2010. We compiled data per population, defined as the breeding population of a species occurring on an island or stretch of coastline in which data were most commonly aggregated for reporting (i.e., a country or discrete sub-region of a large country such as a group of islands or a province). In total, we found data for 3213 breeding populations belonging to 324 seabird species (S1 Table) [17] reported in 357 coastal stretches (S2 Table).

We obtained data from primary sources including journal articles, books, and unpublished reports. We obtained population sizes as breeding pairs or total population; for comparison between the two, we converted records reported in breeding pairs to total population assuming that the population includes 30% non-breeders, a commonly assumed estimate for global seabird studies [1820]. If a population size was reported as a range (e.g., 100–200 breeding pairs), we assumed the population size to be the geometric mean of the minimum and maximum records; the geometric mean is the square root of the product of a pair of values, and is applied in ecology to approximate central tendency [21]. For an example of the population database contents, see S3 Table. The database derived from our study is maintained by the Sea Around Us Project and will be made publicly available at www.seaaroundus.org.

They took numbers from everyone who published anything, There is no data credibility or reliability. They placed this into their model and the output is being treated as empirical evidence..

In their methods they do not even address the ADO and PDO with its resulting shifts in migratory bird route changes they cause.

??? How did this pass peer review???

This isn't even a polished turd! Given their data credibility problems this is worse than manufactured crap... but its still crap..

Yes, they used whatever data they could find on seabird POPULATIONS (324 species) across 357 coastal stretches around the world. A nice sample!
Do you understand statistics?

Can you read or are you an imbecile? That peer-reviewed scientific article did not need ADO, PDO, AMO, ENSO or other ocean climate-related migrations, since they sampled POPULATIONS all over the world.

Yes, it looks like humans are screwing up the ecology world-wide. And you doubt that?

Yes, I assumed that those blindly critical of this research paper were also blindly following the AGW deniers, many of the same folks who supported tobacco company denials. Perhaps I am mistaken, especially if they have a good scientific argument.

For the record, as an independent SR libertarian, I criticize both Dems & Repubs who don't think for themselves.

We obtained data from primary sources including journal articles, books, and unpublished reports. We obtained population sizes as breeding pairs or total population; for comparison between the two, we converted records reported in breeding pairs to total population assuming that the population includes 30% non-breeders, a commonly assumed estimate for global seabird studies [1820]. If a population size was reported as a range (e.g., 100–200 breeding pairs), we assumed the population size to be the geometric mean of the minimum and maximum records; the geometric mean is the square root of the product of a pair of values, and is applied in ecology to approximate central tendency [21]. For an example of the population database contents, see S3 Table. The database derived from our study is maintained by the Sea Around Us Project and will be made publicly available at www.seaaroundus.org.

They took numbers from everyone who published anything, There is no data credibility or reliability. They placed this into their model and the output is being treated as empirical evidence..

In their methods they do not even address the ADO and PDO with its resulting shifts in migratory bird route changes they cause.

??? How did this pass peer review???

This isn't even a polished turd! Given their data credibility problems this is worse than manufactured crap... but its still crap..

Yes, they used whatever data they could find on seabird POPULATIONS (324 species) across 357 coastal stretches around the world. A nice sample!
Do you understand statistics?

Can you read or are you an imbecile? That peer-reviewed scientific article did not need ADO, PDO, AMO, ENSO or other ocean climate-related migrations, since they sampled POPULATIONS all over the world.

Yes, it looks like humans are screwing up the ecology world-wide. And you doubt that?

There is no statistical control or check for properly sourced numbers. They ASSUMED that the other numbers from sources were not contrived or deflated for political gain. This is like giving someone you dont know access to your bank account and assuming that the numbers are A-ok each month..

The paper and its assumptions are garbage.

You think they made up the data? That would jeopardize their future careers?

The Data they found and used were within commonly used statistical analyses.
Even if some of the data they found were inaccurate, the amount of data used was overwhelming and statistically significant ...

"Total number of birds in each year was calculated by summing the MARSS estimates for each population, including estimates from years without population estimates. The total population at the end of the time period was 30.3% of the population at the start, representing a 69.7% loss. Dashed lines represent 95% confidence intervals."
