A Global Discussion about Martha, Extinction and Conservation

Thanks to everyone who tuned in for our #Martha100 TwitterChat with @NMNH (National Museum of Natural History) and @SILibraries (Smithsonian Libraries) yesterday! The chat was a commemoration of the death of the last passenger pigeon, Martha (died Sept. 1, 1914), and a discussion on extinction, conservation, and the importance of historic literature to these fields.

We had some fantastic questions and discussions, as well as great contributions from @fieldmuseum, @SmithsonianArch (Smithsonian Archives), @birdernewjersey (aka Rick Wright, a regular guest blogger for BHL), and @SiobhanLeachman (volunteer with the SI Transcription Center).


Over 350 people participated in the conversation, which produced over 770 tweets seen by over 1.8 million people! BHL saw a 66% increase in the reach of our tweets and a 240% increase in engagement with users on Twitter during the event as compared with our average daily reach and engagements. This translates to a 92% increase in clicks on links, a 117% increase in retweets, a 103% increase in favorites, and a 650% increase in replies. We also saw an increase in our audience, with a 422% increase in Twitter followers compared to our average daily increase.



For a quick snapshot of the conversation, take a look at some of our favorite questions and answers from the TwitterChat:

Q1: @SILibraries: Who was Martha and what is a passenger pigeon?
Answers:
@NMNH: The Passenger Pigeon is an extinct North American pigeon + Martha, the last individual alive, died 9/1/1914
@SILibraries: Passenger Pigeons lived only in North America. @eol has range maps http://ow.ly/B23u5
@BioDivLibrary: Learn more about how the passenger pigeon went extinct http://ow.ly/B25az
@SmithsonianArch: Martha was named after George Washington's wife!
@SILibraries: Some flocks were thought to contain over 2 billion birds, taking days to pass by.
@SILibraries: How did passenger pigeon get its name? From French passenger, which means to pass by.
@Fezook: Was depletion of numbers below that necessary for migration a main cause of passenger pigeon extinction?
@NMNH: essentially yes; numbers declined because of hunting + habitat loss. They were highly social, probably couldn't survive in low numbers.
@BioDivLibrary: Passenger Pigeon may have survived commercial slaughter if nesting grounds not destroyed too http://ow.ly/B24Pa

Q2: @SILibraries: How fast are we losing species?
Answers:
@BioDivLibrary: Recent estimates say by as much as 1000x the natural rate http://ow.ly/B21uY
@SILibraries: This article from @SmithsonianMag says 75% of species extinct in next century http://ow.ly/B21Im
@BioDivLibrary: Among terrestrial vertebrates: 322 species extinct since 1500. 25% average decline http://ow.ly/B21ZA
@ROMbiodiversity: and they've just announced it might be worse http://ow.ly/B227Z

Q3: @SiobhanLeachman: Was wondering if it was the advent of railroads that helped allow extinction?
Answers:
@BioDivLibrary: Absolutely! Railroads allowed millions to be shipped each year http://ow.ly/B20pt
@BioDivLibrary: Cheap meat, large supply & easy distribution via railroads fueled PP annihilation
@SiobhanLeachman: Assumed it took hunters to PP as well
@birdernewjersey: Yes hotels sprang up at railroad terminus when pigeons were around to be shot
@BioDivLibrary: Telegraph was another tech allowing hunters to know quickly where PP were roosting

Q4: @SILibraries: What is so important about Taxonomic Literature?
Answers:
@BioDivLibrary: Lit provides record of species and helps scientists identify new species
@BioDivLibrary: Helps track changes in ecosystems & distributions to identify species & habitats to protect
@HsapiensMarissa: Taxonomic lit bridges gaps in understanding of biodiversity concepts so issues can be targeted holistically
@BioDivLibrary: United Nations requires countries to identify/monitor species w/in borders-BHL provides inventories/info
@BioDivLibrary: It also documents extinct species and their life, morphology, and phylogeny
@SILibraries: How does BHL helps scientists in remote countries?
@BioDivLibrary: BHL provides #openaccess to info on species anywhere/everywhere, even if no access to libraries http://ow.ly/B22xt 
@birdernewjersey: Not just in remote countries: I'd hate to go to the library every time I needed to look something up #badolddays
