Body mass–abundance relationships reveal uneven global energy distribution across body size classes in vertebrates The relationship between species body mass and abundance (MAR-SPP) is a fundamental feature of ecosystems, reflecting whether energy is accumulated in few large organisms or dispersed amongst several ...

Halting predicted vertebrate declines requires tackling multiple drivers of biodiversity loss Global vertebrate populations decline faster in the presence of multiple threats compared to single threats.

A new paper using data from the Living Planet Database (LPD) has been published in @science.org examining how threats are driving global vertebrate population declines.

This work highlights the value of the LPD’s threat data for understanding biodiversity change at a global scale 🌍.

Los corales también duermen por la noche Los llaman los "arquitectos de los ecosistemas marinos" porque sus arrecifes sirven de cobijo a muchísimas especies. También duermen de noche como los humanos.

¿Sabías que los corales también duermen por la noche? 🪸

Degradation of fish food webs in the Anthropocene The decrease in body size driven by the selective species turnover is widely altering fish food web topology and function.

New paper out examining fish food web degradation in the Anthropocene. We show the structure of aquatic food webs are changing-- even when species richness doesn’t. These signals are strongly associated with decreases in body size within fish communities. www.science.org/doi/10.1126/... 🌐🐠🐡🦈🐟

Excited this new paper is out in Science Advances 📄✨ I think the results are important:

To tackle vertebrate declines which are often driven by interacting threats—🦠 disease, 🐍 invasives, 🧪 pollution, 🌡️ climate, multi-threat, systems-level conservation is key 🌍

thanks, solved!

The bottom line is global biodiversity loss isn’t driven by one dominant threat. It’s the combined, cumulative pressure of multiple drivers. To halt vertebrate declines, conservation must tackle them together. 🌍
#Biodiversity #ConservationScience

Vertebrate declines are a due to “death by a thousand cuts”, so removing any single threat slows decline but does NOT reverse it.

ONLY simultaneous mitigation of multiple threats produces non-negative trends.

#BiodiversityPolicy

Contrary to our initial expectations, most threat interactions are additive (~80–90%), and synergistic effects are rare at the global scale.
#Multiplestressors

Threat interactions explain more variation in population declines than spatial or temporal effects.

It’s not just where or when populations are monitored,
it’s how multiple pressures act together.

#MultipleStressors

The steepest annual declines are associated with:
• Invasive species (~ −6%/yr)
• Disease (~ −4.6%/yr)
• Climate change (~ −3.1%/yr)
• Pollution (~ −1.8%/yr)
Impact ranking ≠ prevalence ranking.
#GlobalChange

Habitat loss (27%) and exploitation (31%) are the most common threats.
But they are NOT linked to the fastest declines.
Rarity of a threat does not mean low impact.
#Conservation

Vertebrate populations are declining worldwide.
But which threats are actually driving the steepest declines?
A global analysis of 3,129 vertebrate population time series reveals a surprising pattern 🧵👇
