MOBS 1.0: A Database of Interspecific Variation in Marine Organismal Body Sizes Motivation Body size is a fundamental trait influencing an organism's life history, ecology, physiology and evolutionary dynamics. While extensive body-size databases exist for terrestrial vertebrat...

🧵New paper + open database drop!
The Marine Organismal Body Size ( #MOBS ) Database is now live—85,000+ marine species, from plankton to whales, with standardized size data.
A huge leap for biodiversity, conservation, and climate science. #science #marinelife onlinelibrary.wiley.com/doi/10.1111/...

Join us for our Annual #BESAG2025! We have a great price for #ECRs! send us your nomination by the 4th of August and you can have a free conference ticket and present your exciting research! #freshwater #marine #aquatic Link to register to the conference: www.eventbrite.co.uk/e/besag2025-...

The global human impact on biodiversity - Nature Key measures of biodiversity were quantified and found to be affected by human pressures that shifted community composition and decreased local diversity across terrestrial, freshwater and marine ecos...

A new study by François Keck et al. reveals that human pressures reshape #biodiversity, but don’t always lead to global homogenization. Instead, impacts vary by scale, ecosystem, and type of disturbance. 🌍🧪

hey everyone! i made a list of some useful starter packs (primarily biology/earth sciences with a few bonus things thrown in) to share with friends who have joined bsky in the last week and thought it may be useful for some people here too! 🌍🧪 #SciSky #BioSky docs.google.com/document/d/1...

Hi, I would happily join the third 🌊 :) Thanks a lot for all this!

Are these food webs stable despite the high dynamism of tropical ecosystems?

Thank you

Hi! 'would be interested to join, and I'm pretty sure @davidboukal.bsky.social would be as well :) thanks in advance

I am new here! A little something about me:
*From #SaintMartin Island🌴 #SXM
* PhD degree in #Ecology about interaction between #orchids and mycorrhizal fungi 🌷🍄 at #CeskeBudejovice
*Passionate about #mushrooms
*Now living in France #Montpellier🌞 & looking for a PostDoc

Today is a great day to start the week by deleting X! Thanks #helloquittex #helloquitx!

-> Most invasions lead to neutral community changes, can be beneficial for local communities, by increases in #diversity and in communities stability. Future species invasions may have far-reaching consequences for entire communities and ecosystems, but these consequences need not always be negative

-> 2) #Invasivespecies are not necessarily bad for local communities!
Our findings challenges the conventional wisdom that #invasivespecies are usually harmful and lead to the #extinctions and #collapses of local communities.

The trophic position of #invasivespecies (as #predator or #prey), the #sizes of local and invasive species & the abiotic conditions play a key role for invasion success
-> 1) #Warming and #eutrophication are likely to accelerate invasions of smaller species!

Body size and trophic position determine the outcomes of species invasions along temperature and productivity gradients We model species invasions (characterized by varying body mass and trophic positions) in a simple consumer-resource system along environmental gradients of temperature and nutrient levels. Accounting...

Early 2024, my 2nd paper was out on the key roles of species body sizes and trophic positions to predict the outcomes of #invasivespecies in communities under gradients of #temperature and nutrients levels. A cool study with N. Pichon, A. Sentis & @davidboukal.bsky.social

Ridgeline chart showing the distribution of global daily air temperature differences from the pre-industrial reference period (1850-1900), for every year between 1940 and 2024. Each individual year resembles a hill, shaded in a darker shade of red and further to the right for warmer years. The trend is clearly towards warmer years, with 2024 standing out as first year above 1.5C.

NEW: 2024 has just been confirmed as the warmest year on record, and the first to breach the 1.5C threshold.

We used a ridgeline (Joy Division inspired) chart to visualise daily temperature anomalies since 1940.

2024 clearly stands out with 100% of its days above 1.3C and 75% above 1.5C.

If you are interested for more, here is my 1st plenary talk I gave at the #SIL Congress at Berlin in 2022 for the 4th SIL Student Competition Award

Our model highlights a diversity of potential collapses that may happen in freshwater systems in response to energetic imbalances in multichannel food webs

-> Energetic Imbalances in #freshwater communities may disrupt the food webs, causing sudden population collapses & cascade extinction.

We show that a ‘symmetry in asymmetries’ is critical to maintain multichannel food webs through two compensatory levels of asymmetry (i.e., competitive abilities of the consumers and their vulnerability to predation) that modulate the energy flows in the different food web channels

-> A ‘symmetry in asymmetries’ is critical to maintain multichannel food webs through two compensatory levels of asymmetry that modulate the energy flows in the different food web channels

Using a size-structure #foodweb community model, We demonstrated how the interplay between in differences in mesohabitat productivities and consumer body sizes, typical for many benthic and pelagic communities, promotes species coexistence or extinctions in the food web.

Community structure and collapses in multichannel food webs: Role of consumer body sizes and mesohabitat productivities Multi-channel food webs are shaped by the ability of apex predators to link asymmetric energy flows in mesohabitats differing in productivity and community traits. We show that asymmetries in mesohab...
