Effects of future climate extreme heat events and land use changes on land vertebrates

"By [2100], ... 7895 species are expected to face extreme heat events and/or unsuitable land use changes across their entire range, & thus potentially go globally extinct"

Effects of Future Climate Extreme Heat Events and Land Use Changes on Land Vertebrates

Our study demonstrates how the combined effects of extreme heat events resulting from climate change and land-use change may impact land vertebrates worldwide by 2100. Using global projections across...

Rethinking desert definitions: Bridging the gap between science, policy, and conservation - Ambio

Deserts are often misperceived as desolate, non-productive landscapes. This perception contributes to the misuse of terms like ‘semiarid’ and ‘desertification’, creating ambiguity in how deserts are d...

What was the composition of mammalian biomass on our planet in 1850? Our new study is now out in @natcomms.nature.com

Milo Lab @WIS @milolabwis.bsky.social · Oct 27

1/ Wild mammals now comprise ≈5% of mammal biomass globally. How did this come to be? In our new study in @NatureComms, we estimate that in 1850, wild mammals comprised ≈50% of mammal biomass globally www.nature.com/articles/s41...

Human-induced pressures are expected to intensify this century. @uriroll.bsky.social &co present #ProactiveConservationIndex, a new tool for #conservation prioritization regarding future threats for any group of species, & apply it to all terrestrial #vertebrates @plosbiology.org 🧪 plos.io/3WVRpRH

Distribution of variables used in the calculation of Proactive Conservation Index (PCI) for six species of land vertebrates. Values in spider plots were scaled between 0 and 1. Values on the upper part of each photograph indicate our assigned PCI scores (inner, values closer to 1 indicate a higher conservation priority, relative to other species in the same class), and their IUCN Red List categories (outer, LC, Least Concern; CR, Critically Endangered; DD, Data Deficient; NE, Non-Evaluated). To keep the area of spider plots proportional to PCI scores, the authors have inverted variables that reduce PCI score, and changed their names here accordingly: inverted brood size is named “Reproductive Restriction,” inverted range size is named “Range Restriction,” and inverted protected range is named “Unprotected Range.” Cyrtodactylus metropolis photograph provided by L.

Conservation runs on digital outreach campaigns—videos, memes, hashtags.

But do they work? In a new blog for @ConsEvidence, Gabriel Caetano & I evaluate talk about the evaluation of two campaigns using culturomics (big digital data).
