Nativeness cannot be binary, if is to make sense and be practically applicable at the scale of countries. We propose a graduated definition, in which species native to neighbouring territories are considered "near-native" doi.org/10.1002/oik....

A graduated nativeness definition for overcoming dilemmas and difficulties of vascular plant species
Nativeness is a concept central to biodiversity conservation and invasion biology, but there are several problems related to a classic binary nativeness definition. Dilemmas arise from the dynamic na...

Our latest #SORTEE-led paper is out now in #ProcB! We reviewed data/code-sharing policy clarity, strictness & timing across 275 EcoEvo journals We also worked with #ProcB & #EcologyLetters to assess initial compliance with sharing mandates. Huge team effort! 👉 doi.org/10.1098/rspb...

From policy to practice: progress towards data- and code-sharing in ecology and evolution | Proceedings of the Royal Society B: Biological Sciences
Data and code are essential for ensuring the credibility of scientific results and facilitating reproducibility, areas in which journal sharing policies play a crucial role. However, in ecology and evolution, we still do not know how widespread data- and ...

It's like an episode of black mirror in which, instead of fixing the poisonous two-sided market that favors oligopoly publishers, funding orgs decide to try out *price controls*.

Could we use community/citizen/participatory science data to estimate population extinction risk? Our results comparing the estimates from eBird and from a standardized survey suggest we can!! #ornithology #ecology #conservation See our detailed tutorial oaccolombia.github.io/vpm_eBird/vp...

Very disappointed with the Wiley production team who did a bafflingly abysmal job handling our accepted manuscript (for 5+ months!), but we are grateful to the editor for pushing through for us.

The original SoIB 2023 report is available for free, and is filled with wonderful illustrations! You can find the PDF report as well as the raw data sheets of our results over at t.co/FrxHFwTcfX (5/5)

Though grim, our findings can help guide research and #conservation action in the country, and also inform global assessments on resident species for which systematic data are lacking. (4/n)

SoIB abundance #trends broadly match results from elsewhere. 204 spp. have declined in the long term and 142 are currently declining! Open habitat birds are struggling as a group. (3/n)
Trend graph showing change in abundance index for bird species grouped into habitat specialisation composites. Birds that require glassland & scrub have shown the strongest decline, whereas those with no habitat specialisation seem to have remained stable.

We delve into the nitty-gritty methodological details (inc. best practices for analysing eBird data) that enabled us to generate 3 metrics (long-term change, current annual trend, range size) for 942 Indian birds & thereby assign Conservation Priority status for each. (2/n)
Illustration showing numbers of bird species assigned to each of the three Conservation Priority Status categories. (178 High, 323 Mod, 441 Low)

🚨 New paper alert! We detail the MAMMOTH @stateofindiasbirds.in effort, hoping that our analytical framework (and #OpenSource codebase), serves as a blueprint for similar #StateofBirds assessments in other #GlobalSouth regions. (1/n)

🚨 Stat tips 🚨 Are you aware of the regression to the mean #RTM effect? This artefact is often overlooked in #ecology & especially in biodiversity resurveys 🌳🍄🦔🦅🦎🦋🐝🐞 It basically shows up each time you investigate changes between 2 time events: t2 vs t1 Let me unfold it for you 🧵

#HiSciSky 🌏 I'm an ecologist from India and my work revolves mostly around birds; soon starting a PhD! Some specific interests include community and functional ecology, macroecology and biogeography. Beyond profession, birding occupies a prominent role in my life and is much more than a hobby!
