“…There is a lack of information on charophytes in Iran, just a few works have been done in the past; Braun and Nordstedt (1882) reported Chara foetida ( Chara vulgaris ) from Isfahan and Kashan, Leonhard (1981) collected Chara vulgaris and Nitella hyalina in the Tabas region, Carle and Frey (1977) reported vegetation with Chara tomentosa from Lake Maharlo near Shiraz, and Hutorowicz (2008) studied the oospore of C. tomentosa from Holocene sediments of Lake Zeribar. These studies are all restricted in extent, or detail, and there is a clear need to document the Characeae of Iran.…”

Morphological characters of 10 species of Chara from different localities in northern, western and central Iran have been analyzed, with Nitella hyalina and Tolypella glomerata as outgroups. Phenetic and cladistics analyses of populations belonging to the 10 Chara species were undertaken to reveal their inter‐population morphological variation and inter‐specific relationships. Clustering was based on 54 characters (41 qualitative and 13 quantitative). This produced two major clusters, grouping Chara crassicauliss, C. vulgaris var. longibracteata, C. vulgaris var. vulgaris and C. contraria separate from C. grovesii, C. gymnophylla var. gymnophylla, C. gymnophylla var. rohlenae, C. kirghisorum and C. tomentosa. A smaller cluster of C. socotrensioides, C. fibrosa and Chara sp. was separate from these two clusters. A factor analysis identified the most variable morphological characters as type of cortification, prescence and length of the spine cells, stipulode length, type of branchlet cortication, bract cells length, placement of the gametangia, character of end segment, length of branchlet and internode, development of posterior bract cells, oogonia length and width, oospore length, width and length/width ratio, fossa breath, and number of striae.

Revisiting Zeribar lake sediments: Effects ofclimate change on human development in Zagros

Zeribar Lake, located in the west-central Zagros mountains, serves as a key record for understanding the environmental and climate history of West Asia. Studies beginning in the 1960s have examined the lake's sediments to explore how changes in the environment might have influenced major human developments, including the start of the Neolithic period and the formation of early societies. Early research, limited by less precise radiocarbon dating methods, suggested that environmental factors had little impact on the development of cultures. However, with improved dating techniques, a clear link has been established between environmental events and significant stages in human evolution. Analysis of pollen from Zeribar Lake has provided a detailed picture of the region's ecological past. The data shows a significant change from the sparse, cold conditions of the late Pleistocene and early Holocene to the rich oak forests that appeared in the mid-Holocene. This change, previously thought to be caused by more rain, is now understood to be the result of a considerable decrease in temperature, with glaciers once widespread in the area. Updated radiocarbon dating and new interpretations of pollen data suggest that agriculture began earlier than previously thought, around 14,000 years ago, indicating that shifts in the pollen record may reflect the beginnings of farming rather than changes in the climate. These climate changes, initially thought to be minor until 8,000 years ago and believed to involve only slight temperature variations, are now viewed from a different perspective. Despite these revelations, the debate continues among scholars regarding the extent of climate's role in shaping human progress. This article aims to weave together the multifaceted strands of Zeribar Lake's story, bridging paleoecology and archaeology to shed light on the complex dance between humanity and its environment in the Zagros region. It is an endeavor to bolster the bedrock of knowledge for future scholarly pursuits.

Oospores of Chara tomentosa from Holocene sediments of Lake Zeribar (Iran)

Abstract: Biometric measurements were performed on oospores of Chara tomentosa from Core 63-J from Lake Zeribar in Iran. The partially fossilized oospores examined did not differ significantly in dimensional measurements, number of ridges, or colour from oospores of modern specimens of C. tomentosa.
