The war in Ukraine is changing plausible future socioeconomic scenarios leading to an unexplored outlook for biodiversity

open access: yesConservation Science and Practice, Volume 6, Issue 9, September 2024.
We discuss how recent policy changes to global trade routes, agriculture, and energy production in response to the escalation of the war in Ukraine are impacting socioeconomic scenarios used to set and assess global biodiversity targets. We call for the re‐evaluation of existing biodiversity targets with newly developed scenarios that reflect the ...

Habitat suitability of biocrust communities in a cold desert ecosystem

open access: yesEcology and Evolution, Volume 14, Issue 7, July 2024.
Biocrusts are dominant primary producer communities inhabiting the McMurdo Dry Valleys of Antarctica. We found that gravimetric water content, electrical conductivity, and snow frequency are the top predictors of biocrust presence and biomass. We predict that biocrusts are present in 2.7 × 105 m2 and contain 11–72 Mg of aboveground carbon in the Lake ...

Foliar spectra accurately distinguish most temperate tree species and show strong phylogenetic signal

open access: yesAmerican Journal of Botany, Volume 111, Issue 4, April 2024.
Abstract Premise Spectroscopy is a powerful remote sensing tool for monitoring plant biodiversity over broad geographic areas. Increasing evidence suggests that foliar spectral reflectance can be used to identify trees at the species level. However, most studies have focused on only a limited number of species at a time, and few studies have explored ...
