Astragalus ecomorphology in Quaternary elephantids
Journal of Quaternary Science, EarlyView.ABSTRACT The astragalus plays a fundamental role in the graviportal locomotion of proboscideans, reflecting the biomechanical constraints imposed by large body masses. This study analyses the morphological variability of the astragalus in Quaternary elephantids using linear biometry and 3D geometric morphometrics, incorporating an unpublished ...

Abrupt climate changes of the last deglaciation detected in a Western Mediterranean forest record [PDF]
, 2009 Abrupt changes in Western Mediterranean climate during the last deglaciation (20 to 6 cal ka BP) are detected in marine core MD95-2043 (Alboran Sea) through the investigation of high-resolution pollen data and pollen-based climate reconstructions by the ...

Nordic Journal of Botany, EarlyView.The Irano‐Turanian Floristic Region harbors a rich flora, but our understanding of the development of this diversity is limited by a lack of data on phylogenetic relationships and biogeographic patterns of endemic and more widespread plants. Hypotheses of in situ diversification versus allopatric diversification were tested using Iris subgen. Scorpiris,

International Journal of Osteoarchaeology, EarlyView.ABSTRACT Studying goose domestication through archaeological finds has been challenging due to the similar skeletal morphology of the European domestic goose and its wild progenitor, the greylag goose (Anser anser). We analyzed stable carbon (δ13C) and nitrogen (δ15N) isotopes from bone collagen of subfossil domestic and potentially domestic geese to ...

Understanding plant responses to drought: how important is woody tissue photosynthesis? [PDF]
, 2013 Within trees, it is known that a part of the respired CO2 is assimilated in chlorophyll-containing stem and branch tissues. However, the role of this woody tissue photosynthesis in tree functioning remains unclear, in particular under drought stress ...
