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.

Palaeobathymetry of the Abderaz Formation using foraminifera, Iran [PDF]

open access: yes, 2009
Abderaz Formation at its type section with an age of Turonian-early Campanian and a thickness of 300 m contains light grey shale and marl. The study of the planktonic foraminifera in isolated form led to differentiate three morphotype groups.

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.

Assessing Genetic Diversity and Habitat Suitability in Endemic Iranian Darevskia (Reptilia: Lacertidae) Under Climate Change

open access: yesJournal of Zoological Systematics and Evolutionary Research, Volume 2025, Issue 1, 2025.
The Iranian Plateau, a biogeographic hotspot shaped by Pleistocene refugia and topographic complexity, hosts six endemic Darevskia lizard species (D. caspica, D. defilippii, D. schaekeli, D. kamii, D. steineri, and D. kopetdaghica), ideal for studying evolutionary responses to environmental changes. These species, characterized by cryptic diversity and

Protecting alpine biodiversity in the Middle East from climate change: Implications for high‐elevation birds

open access: yesDiversity and Distributions, Volume 30, Issue 5, May 2024.
Abstract Aims The Middle East, located in the arid belt of the Earth, is home to a diverse range of biodiversity, with its mountain ecosystems being the most important centres of species diversity and endemism. In this study, the impact of climate change on alpine bird species in the Middle East was assessed across five mountain systems: Alborz–Kopet ...
