Species loss in key habitats accelerates regional food web disruption - Communications Biology Simulating extinctions across regional food webs reveals that losing species from one habitat— especially wetlands—can cascade to others, accelerating multi-habitat food web collapse, highlighting the...

🚨 Hot off the press! We show that species loss from key habitats (like wetlands) accelerates secondary extinction in regional multi-habitat food webs. Also, we show the importance of common species to regional food web robustness. doi.org/10.1038/s420...

Nice reporting from @meganewald.bsky.social on point if use #eDNA detections of West African Manatees

Excited for what the future holds in being able to rapidly test for endangered cryptic species - particularly the rotund ones

Want to learn more about using #eDNA for #conservation? Take the introductory course just added to WILDLABS to learn the fundamentals of eDNA, like:
- Sample collection methods
- Statistical analysis techniques
- Interpreting results

Monitoring the biodiversity of small mammals and amphibians in the Pumalin park using #eDNA in collaboration with Rewilding Chile. We use a peristaltic pump and long filtration to concentrate rare DNA in the sampling capsules.

Monitoring the effect of protection on wildlife recovery in one of the largest wetland of Argentina, also a Ramsar site, the Ibera wetland, what a sight! @virginiemarques.bsky.social

Postdoctoral Researcher in Tectono-Geomorphic Processes and Mountain Biodiversity

The Laboratory of Ecosystems and Landscape Evolution at the ETH Zurich is looking for candidates to fill a post-doctoral position as part of the fully funded SNSF Consolidator project “Burgeon”.

Inferred patterns of biodiversity for angiosperms across the three diversity facets and the two growth forms (i.e., woody versus herbaceous). Rows from top to bottom denote species richness (A and B), phylogenetic diversity (C and D), and functional diversity (E and F), respectively. Columns on the left denote the diversity facets of woody angiosperms (A, C and E), and columns on the right denote the diversity facets of herbaceous angiosperms (B, D and F).

Estimated carbon fluxes for different modes of vegetation adaptation to climatic changes. (A) Land-derived organic carbon burial (Flocb) and (B) silicate weathering (Fsilw) for two slow-adapting vegetation implementations and an immediate adaptation implementation (no eco-evolutionary dynamics).

What is the role of a continuously evolving #vegetation on 🌎’s carbon-climate regulation system? The balance between past environmental changes & vegetation capacity to adapt could've strongly influenced #carbon fluxes between 🌎’s surface & #geologic reservoirs. www.science.org/doi/10.1126/...
