Doubled-edged Dispersal! In the Anthropocene, animals disperse a lot of things. From seeds and nutrients, to pathogens and invasives. Our new paper discusses the need to balance trade-offs when both desirable and undesirable functions occur simultaneously www.sciencedirect.com/science/arti...
A general framework for what makes a novel ecosystem.. wonderfully led by @mattkerr.bsky.social
Matt Kerr@mattkerr.bsky.social · 6mo agoOur new paper presents a framework for analysing the processes that generate novel ecosystems, discussing different conceptual and practical approaches across ecological disciplines. You can read it, open access, in @methodsinecoevol.bsky.social besjournals.onlinelibrary.wiley.com/doi/10.1111/...
🌍In a new @econovoau.bsky.social paper in Methods in Ecology & Evolution, led by @mattkerr.bsky.social, we present a process-based framework linking compositional, functional, abiotic & social dimensions of novel ecosystem trajectories♨️🌿 besjournals.onlinelibrary.wiley.com/doi/10.1111/...
The making of novel ecosystems: A process‐based framework for measurement, analysis and application
Ecological novelty is emerging rapidly due to global change drivers such as climate shifts, species introductions, defaunation, and land-use transformation. These changes challenge how we assess, ...

Our January issue is now live: www.nature.com/natecolevol/... Featuring research on 🧪 🐝 pesticide impacts on wild bees 🪺 population genomics of avian brood parasitism 🌱 the origins of terrestrial herbivory Cover image from Abraham et al. www.nature.com/articles/s41...
Earth's largest land animals are limited by salt. Sodium availability constrains the density and distribution of elephants, giraffes and rhinos across Africa, and offers a new explanation for the so-called 'missing megaherbivores'. www.nature.com/articles/s41... Free access: rdcu.be/eTPY2
🦁Predators have a strong sex-bias when it comes to their favourite prey 🌏 In their new paper @andrewabraham.bsky.social quantify large carnivore sex-biases in Africa and examine how wildlife managers can replicate such effects when natural predators are missing 👇 buff.ly/Q8cB4Qq
Super important work by Tim Kuiper and co!
Tim Kuiper@timkuiper.bsky.social · last yr.Still can't believe we got onto the cover of Science! Across 11 reserves and 7 years, we found that dehorning achieved large reductions in poaching, but it's not a magic bullet Full article: www.science.org/doi/10.1126/... Popular version: www.dailymaverick.co.za/article/2025...
Great opportunity to lead discussions in biodiversity conservation for ECRs
Celesté Maré@celestemare.bsky.social · last yr.Are you an early career researcher (ECR) passionate about #Conservation? See below for an amazing opportunity to work with fellow motivated ECRs to explore and develop important themes around Biodiversity conservation! Deadline is 12 June 2025. www.linkedin.com/posts/celest...
Closing tomorrow! Last chance to apply for postdoc to explore the role of animals in savanna ecosystem productivity & nutrient cycling! Link to job: tinyurl.com/53dy4584 #savanna #termites #largemammals
The "great whale conveyer belt" that transports nitrogen, carbon, and biomass from high latitude feeding grounds to concentrated low latitude breeding grounds in gray, humpback, and right whales. Lovely figure by A. Boersma doi.org/10.1038/s414...
Sure to be an interesting talk by @andrebellve.bsky.social.. also, be prepared for some excellent graphics! #scicomm
André Bellvé@andrebellve.bsky.social · last yr.Lecture at 12 PM EST today - sign up if you are interested in a long-term perspective of seabird declines and what it means for nutrient transport! bsky.app/profile/biog...

Half of British households feed birds.. but should we? Ft our recent study on potential issues of nutrient pollution. www.theguardian.com/environment/... Full paper: esajournals.onlinelibrary.wiley.com/doi/full/10....
Should we stop feeding birds, what happens if we do and does it spread disease?
Half of British households put food out for birds but there is increasing concern it can spread disease

Nice coverage by Nat Geo of our new paper quantifying the longest nutrient transport system in the world: whale pee www.nationalgeographic.com/animals/arti... For the full paper, see here: www.nature.com/articles/s41...
The stunning power of whale pee
A single whale can produce more than 250 gallons of urine in a day. It helps sustain life across the ocean.

So what actually happened when the dinosaurs died?🦕 Using simple ecological rules*, we explore how the interplay between ecosystem engineering, seed size and light environment can explain temporal patterns of animal and seed sizes from the fossil record🌳🐘🐀🌱 onlinelibrary.wiley.com/doi/10.1111/...
Ecosystem engineers alter the evolution of seed size by impacting fertility and the understory light environment

A great thread by @alexanderlees.bsky.social on the positive and negative impacts of bird feeding, including our recent paper highlighting issues of nutrient pollution and changes to local biogeochemical cycles: esajournals.onlinelibrary.wiley.com/doi/10.1002/...).
Alexander Lees@alexanderlees.bsky.social · 2y agoQuick thread on some new papers on the science of impacts of bird feeding since the publication of our papers here www.sciencedirect.com/science/arti... and here britishbirds.co.uk/journal/arti... #Ornithoogy #UKBirding🧵 1/

It's been 10 yrs since Marius the giraffe was controversially culled by Copenhagen Zoo. So, what's happened since? Many zoos limit reproduction to avoid surplus animals and public backlash. We argue this approach fails the conservation & education mandate of zoos 🧵: www.pnas.org/doi/10.1073/...

The time it takes for food to travel through an animal's body is important for nutrient assimilation and functions like seed dispersal. Here, we show that intestine length better predicts retention time than body mass; a simple, but important concept: www.sciencedirect.com/science/arti...
