Major update to BioTIME 2.0, world’s largest biodiversity time-series database

BioTIME 2.0 is the largest biodiversity time-series database on the planet and gives unprecedented insight into global biodiversity.

idiv.de

While 'flashy' papers are great, analyses are ephemeral. It's the data, its preservation and organization that will persist. Honored to be involved with this amazing team on what I think are some of the most important biodiversity data out there. BioTime v 2.0.

🚨New data paper/open data alert!🚨 BioTIME v2.0 is out now! We've expanded the database with improved spatial and taxonomic coverage, with a new R package! As always, free, public, and open acess :) Paper: onlinelibrary.wiley.com/doi/10.1111/... Database: biotime.st-andrews.ac.uk

What a wonderful paper!! Really clear results and extremely important research!! I will use it in my classes Congrats Thiago Gonçalves-Souza @natejsanders.bsky.social @jon-chase03.bsky.social @nickhaddad.bsky.social www.nature.com/articles/s41...

Thanks Rob, for writing such a great News & Views about our paper! A huge honor (or I guess I should write honour given your new position) to have your thoughts!

New article out today in @nature.com by Gonçalves-Souza, @nickhaddad.bsky.social, @jon-chase03.bsky.social et al. on forest fragmentation and biodiversity: www.nature.com/articles/s41... A must read for anyone interested in this topic. See my summary here: www.nature.com/articles/d41...

Is fragmentation bad or good for biodiversity? Yes! We use a classical competition-colonization metacommunity model to show that fragmentation can increase or decrease diversity depending on the total amount of habitat in the landscape. 🧪 www.nature.com/articles/s41...

Habitat amount modulates biodiversity responses to fragmentation - Nature Ecology & Evolution

How biodiversity responds to habitat fragmentation per se is debated. Here the authors combine metacommunity simulations with reanalysis of empirical metacommunities to show that the amount of habitat...

This week, embattled UCLA EEB Professor Priyanga Amarasekare faces additional disciplinary hearings. She offers a thorough defense of herself--and transparency on the history of charges & outcomes in her cases--here: pamarasekare.org

Holly Moeller@mixotrophe.bsky.social · 3y ago

As Prof. Priyanga Amarasekare's heartbreaking saga at UCLA drags into another year, I've compiled a thread of articles written about the situation. My sardonic take: Some people didn't like to be accused of racism and decided to destroy her career over their hurt feelings. 1/21

After 6 years of postdoc-ing with us at iDiv, the Synthesis group says goodbye to Emma Ladouceur. She had such an incredible influence on us all, scientifically and personally. We will miss her, but wish her well and onto bigger and better things at the University of Prince Edward Island!

For those following the ongoing saga of Priyanga Amarasekare—a major update. She speaks out, addressing all charges! This would make for a dramatic novel or Netflix series. But no, it’s the life of our brilliant and deeply caring colleague and friend. www.pamarasekare.org

Congrats to all! But super pleased to see the early career list has Melissa Guzman, whom I was privileged to help nominate (and work with; she’s a 🌟) and Diogo Provete, who is spending the next year at IDiv in my research group, on a Humboldt foundation sabbatical! www.esa.org/blog/2024/04...

Congrats to Zhonghan Wang for leading this great study in Ecology looking at habitat fragmentation effects on the Thousand Island Lake islands across multiple trophic levels. Was great having him visit iDiv on a CAS scholarship from China. doi.org/10.1002/ecy....

Higher trophic levels and species with poorer dispersal traits are more susceptible to habitat loss on island fragments

<em>Ecology</em> is a leading journal publishing original research and synthesis papers on all aspects of ecology, with particular emphasis on cutting-edge research and new concepts.

Nice new modern take on the old pseudoreplication problem (here discussed much more accurately as subsampling) in experimental design. onlinelibrary.wiley.com/doi/epdf/10....

As director of CESAB, I'm incredibly proud to share the latest article of our postdocs today in Ecology Letters. 👏 They call for a more ethical academic publishing landscape but also ask to not let only the Early Career Researchers pay the price of this paradigm shift ! doi.org/10.1111/ele.... 🧪🌍

"Amarasekare knows she could get in trouble for talking about any of this, especially to a reporter. But she said she’s tired of feeling muzzled by confidentiality rules and wants to restore her reputation." www.chronicle.com/article/ucla...

UCLA Punished a Prominent Scientist for ‘Destructive and Harmful Conduct.’ She Says It’s ‘Unjust Persecution.’

Priyanga Amarasekare was suspended and later put on involuntary leave for breaching the Faculty Code of Conduct. She hopes that speaking out will help clear her name.

🚨New paper! Is homogenization really that more common than differentiation? - not really, our latest work shows that one pattern can be as common as the other. Another great work and collaboration led by this amazing team👇

Jonathan Chase@jon-chase03.bsky.social · 2y ago

The lack of evidence for declining local diversity through time must be because everything is homogenizing, leading to larger-scale losses. Right?! Nope, says our analysis of 500+ meta-communities through time just published in Science Advances 🧪🌎🐟🌳🦋 🐦🦌 www.science.org/doi/10.1126/...

Synthesis reveals approximately balanced biotic differentiation and homogenization

Homogenization is most common at large temporal and spatial scales but is balanced by differentiation at smaller scales.

So it seems that UCLA, on top of punishing a POC professor for speaking out against racism, has also done nothing against professors for engaging in racist behavior

We have a new call for 'Synthesis' projects at iDiv. Looking forward to more great 'community-driven' synthesis work happening here. Feel free to reach out with questions, etc. www.idiv.de/en/sdiv/calls

Nice to have our Ukrainian 🇺🇦 colleagues back for another #sDiv workshop at iDiv on the scaling of grassland biodiversity. This week, traits and the dreaded beta-diversity! Expertly led by Oksana Buzhdygan and Anna Kizemko

Do plants and microbes show the same response to fragmentation? Are the mechanisms similar? It was a pleasure exploring these questions in a paper led by Yueqing Song, Ling Wang et al in the J. Ecology in degraded grassland remnants in China. doi.org/10.1111/1365...

Come join us @ iDiv👇

Marten Winter@smartenwinter.bsky.social · 3y ago

Surely one of the most exciting research centres & work places for biodiversity related topics iDiv (www.idiv.de where I work) has opened a call host & support externally funded Junior group projects Happy to talk & answer questions. www.idiv.de/en/groups-an...

So excited to announce our search for an Assistant Professor focused on understanding plant response to climate change! Come join us at UC Riverside aprecruit.ucr.edu/JPF01827
