Honored to join this group of scientists & park managers tackling how to revive Fernandina's tortoises. A hard challenge, but everyone's love for these islands showed. Thanks @parquegalapagos @savegalapagos @rewild for leading the way. 🐢
Parque Galápagos

Fernanda y el desafío de conservar una historia única de Galápagos Fernanda es, en la actualidad, el único ejemplar vivo conocido de la tortuga gigante de Fernandina. Su existencia plantea una gran interrogante: ¿qué podemos hacer para preservar una especie de la que conocemos tan poco? Para buscar respuestas, la Dirección del Parque Nacional Galápagos, con el apoyo de @savegalapagos y @rewild, reunió durante tres días a guardaparques y científicos nacionales y extranjeros para definir una hoja de ruta para los próximos cinco años. Las acciones incluirá nuevas expediciones a Fernandina para buscar evidencias que permitan conocer mejor la especie; análisis de restos subfósiles y material genético; revisión de colecciones de museos y registros históricos; y la identificación de posibles ejemplares de origen Fernandina fuera de Galápagos. También fortaleceremos el manejo reproductivo de Fernanda, explorando herramientas de reproducción asistida y estableciendo un banco de material biológico para preservar células y material genético. Sabemos que es un desafío complejo, por eso cada paso se dará con rigor científico y sin anticipar resultados. Nuestro compromiso es seguir investigando y utilizar todas las herramientas disponibles para ampliar las posibilidades de preservar este linaje único.

Do you code? Want to help #Ornithology with an AI challenge for identifying birds by sound? Checkout the BirdCLEF_2022 competition, put together by @CornellBirds, the Google Bioacoustics group, and others: kaggle.com/c/birdclef-2022

WHAT flower blossoms in the cold of winter, is mostly blackish (and white)? And WHO thought to name it "Fetid adder's tongue"? Blooming in our front yard...

New paper out in @NatureComms! We show population differentiation in Wallacean & New Guinean birds is consistently & positively correlated with barrier strength and a species’ altitudinal floor: doi.org/10.1038/s41467-021-2…

Amazing work by Google AI engineers creating automatic classifiers to identify birds in recordings. Significant improvements to the algorithms bring us closer to having functional tools for science. ai.googleblog.com/2022/01/se… #ornithology @googleai @calacademy

Another rare beauty from Maldives #mesophotic ecosystems, Plectranthias winniensis. This one is very cryptic, and this is the first good picture I take of it in situ at about 105m depth. #hopeforreefs #perpetualplanet

Yes! We will be teaching our Master Birding Course in 2022! This is a great class for advanced birders who wish to really hone their birding and environmental leadership skills. For more information, click here: calacademy.org/events/scienc… @calacademy @GGAudubon

Goodbye Galapagos! What an amazing research trip, working with @chavecito76, Ezra Mendales and Pooneh Kalhori on island birds. Thanks for the fantastic data, Galapagos! @calacademy @GSCGalapagos

Katharine Brandagee gave up her position for Alice Eastwood to come to @calacademy ! Happy to say this spirit of women supporting women is alive at CAS today 💜@RaynaCBell @alisonkestrel @flylogeny @rkim1853 @ArachnologyNerd @jacobs_sarahj @RebaFay 💜

Canadian-born Alice Eastwood succeeded Kate Brandagee as procurator and Head of the Department of Botany @CalAcademy. She rebuilt the herbarium from the 1500 type specimens she saved from burning in the 1906 earthquake to nearly a third of a million, and described 395 species.
In an old photograph, Eastwood views a fault line crack in a grassy hill.

That’s a wrap! Galápagos field season completed. Happy students (sugar high), samples collected, and great memories made. A treat to share this time with @CASBirdman @PoonehKalhori Ezra Mendales. @GSCGalapagos @SFStateBIO @calacademy @USFQ_COCIBA @jocotoco_org – at Galapagos, Ecuador

Great hike to the highest point on Santa Cruz Island in the Galapagos. Plus a new life bird for me - Galapagos Rail, with @chavecito76 who studies them….

Successful summit to the highest point on Sta Cruz-Island: Cerro Crocker. It has been a blast after 2 years of hiatus. Couldn’t be more grateful for having @CASBirdman as a colleague and two rockstar students @PoonehKalhori @Ezramenda114 #Galapagos @SFStateBIO @calacademy

Excellent work led by Devon DeRaad in Rob Moyle's lab at the University of Kansas sorting out the relationships of Chalophaps doves! Cool story of how birds diversified across these islands... authors.elsevier.com/c/1d-PP… #ornithology

The San Cristóbal Vermilion Flycatcher (Pyrocephalus dubius) hasn't been seen in many years and may be extinct. But with @DarwinFound biologists from Galápagos Islands, we are sequencing their genomes from 100+ year old specimens @calacademy! #HispanicHeritageMonth

Evidence that toxin resistance in poison birds and frogs is not rooted in sodium channel mutations and may rely on "toxin sponge" proteins. A new study from Fayal Abderemane-Ali, @ElectrosomeUCSF, @megan_kobiela, @CASBirdman et al. bit.ly/37mau5Z #MolecularPhysiology

Much of conservation depends upon our perceptions and emotions. Colleagues who study owls are conducting a survey to understand how people think and feel about owls! Please take a minute to fill out their questionnaire... you-and-the-owls.webnode.com… @RoulinRoulin

Excited to be using PacBio HiFi technology to get a reference genome for the Galapagos Vermilion Flycatchers - and unlock the DNA in our 100+ year old specimens... #HiFiExhibit @calacademy @DarwinFound
