On the hybrid origin of the C2 Salsola divaricata agg. (Amaranthaceae) from C3 and C4 parental lineages

open access: yesNew Phytologist, Volume 234, Issue 5, Page 1876-1890, June 2022., 2022
Summary C2 photosynthesis is characterised using recapturing photorespiratory CO2 by RuBisCo in Kranz‐like cells and is therefore physiologically intermediate between C3 and C4 photosynthesis. C2 can be interpreted as an evolutionary precursor of C4 and/or as the result of hybridisation between a C3 and C4 lineage.

The bird remains from WF16, an early Neolithic settlement in southern Jordan: Assemblage composition, chronology and spatial distribution

open access: yesInternational Journal of Osteoarchaeology, Volume 31, Issue 6, Page 1030-1045, November/December 2021., 2021
Abstract Excavations at the early Neolithic settlement of WF16 in Faynan, southern Jordan, 11.84–10.24 ka BP, recovered 17,700 bird bones, of which 7808 could be identified to at least family level.

Foraging patterns of habitat use reveal landscape of fear of Nubian ibex Capra nubiana

open access: yesWildlife Biology, Volume 18, Issue 2, Page 194-201, June 2012., 2012
Different environmental features may serve as cues of the risk of predation. Therefore, when foraging in heterogeneous landscapes, the costs of predation for optimal foragers should vary along with the environmental features. In our study, we describe how foraging costs of predation vary spatially for Nubian ibex Capra nubiana with respect to ...
