From Site Selection to Characterization: Assessment of Potential Reservoirs in the Lurestan Basin of Iran for Carbon Sequestration

open access: yesGreenhouse Gases: Science and Technology, Volume 15, Issue 3, Page 319-332, June 2025.
ABSTRACT The increasing global focus on carbon sequestration underscores the need for comprehensive CO2 storage atlases, extending beyond Europe and America to other countries that are significant contributors to carbon dioxide emissions. This article addresses this imperative by examining the CO2 storage potential in the Lurestan area of Iran, with a ...

Functional Signatures of Surface Pollen and Vegetation Are Broadly Similar: Good News for Past Reconstructions of Vegetation

open access: yesJournal of Biogeography, Volume 52, Issue 5, May 2025.
ABSTRACT Aim Pollen assemblages are widely used to infer paleoenvironment features, aiming at reconstructing both past climates and biomes. However, the functional link between environmental conditions and pollen assemblages is not straightforward and requires thorough testing to be used confidently.

Biogeographic Patterns of Iranian Lepidoptera: A Framework for Conservation

open access: yesDiversity and Distributions, Volume 31, Issue 3, March 2025.
ABSTRACT Aim The contact zone of three zoogeographic realms, the Palearctic, Saharo‐Arabian and Oriental, is an evolutionary cradle of high species richness and endemism in Iran. In this study, we investigate statistically inferred bioregions of Lepidoptera in this region.
