Wetlands as environments of early human occupation: A new classification for freshwater palaeowetlands

open access: yesThe Depositional Record, EarlyView.
A new classification for inland freshwater palaeowetlands to be used in the field or core laboratory by sedimentologists, providing examples from the Guadix Basin (southern Spain). Abstract Present wetlands have proven to be delicate, biodiverse ecosystems, that are natural sinks for CO2 and act as good indicators for climate changes.

Recent origin of low trabecular bone density in modern humans [PDF]

open access: yes, 2014
Humans are unique, compared with our closest living relatives (chimpanzees) and early fossil hominins, in having an enlarged body size and lower limb joint surfaces in combination with a relatively gracile skeleton (i.e., lower bone mass for our body ...

Ground ice as indicator of the Pleistocene history of the Russian Arctic

open access: yesЛëд и снег, 2015
Based on the analysis of massive ground ice origin, the geological development of the Russian Arctic in the Quaternary period has been considered. A classification of massive ice with two new genetic types (submarine and coastal-marine) and new mechanism

Stratigraphic units of the Apulian Tavoliere plain (Southern Italy): Chronology, correlation with marine isotope stages and implications regarding vertical movements

open access: yes, 2010
The geologic study of the Apulian Tavoliere plain (Apulia region, southern Italy) is extremely difficult due to the scarcity of outcrops and fauna that could be used for dating. The survey in progress of the 1:50,000 scale geological sheet no.

Fifty years of research on the Joulters ooid sandbody—Impact on carbonate sedimentology and diagenesis and lessons learned from an invaluable analogue

open access: yesThe Depositional Record, EarlyView.
The Joulters ooid sandbody of northern Great Bahama Bank is a vast expanse of muddy ooid sands partly rimmed by clean ooid sands and formed into a relatively thick layer of significant extent. Knowledge of the development of depositional and diagenetic patterns in the Joulters example has forwarded our general understanding of carbonate sedimentology ...

Late Pleistocene to Holocene diversification and historical zoogeography of the Arabian killifish (Aphanius dispar) inferred from otolith morphology

open access: yesScientia Marina, 2012
Aphanius dispar (Rüppell, 1829) is a common marine-euryhaline teleost fish in the Near East that has undergone considerable intraspecific differentiation. Otolith morphology is used to analyse the diversity within A.

Bahaman patch reefs: Numerous and neglected

open access: yesThe Depositional Record, EarlyView.
Abstract Phanerozoic patch reefs are extensively studied because they are abundant and are potential reservoirs for valuable fluids. In contrast, geologic studies of modern reefs have largely focused on platform margins, leaving patch reefs comparatively neglected. What conditions favour patch‐reef development?
