Viable Seeds

Although viable seeds of Mediterranean dry-fruited shrubs are found in herbivore dung, the ecological importance of this observation is still not well understood. We analysed seed retrieval percentages, defecation time and germinability after sheep gut passage for the five most common shrub species of an area in central Spain (Retama sphaerocarpa, Cytisus scoparius, Halimium umbellatum subsp. viscosum, Cistus ladanifer and Lavandula stoechas subsp. pedunculata). Five ewes were fed seeds, and their dung was collected regularly during the following week. Seeds were hand-sorted from dung subsamples and tested for germinability. The defecated seeds were clustered in time, with a majority retrieved in the 24–40 h period, although over 1% of the seeds were retained in the gut for more than 72 h. Data suggested a possible link between seed size and retrieval, with medium-sized seeds less damaged (16–23%) than larger and smaller seeds (10–12%), although only a small number of species were studied. Germination results showed an increased percentage of germination after gut passage for H. umbellatum (x2 test, P<0.05) and a marginally significant difference for C. scoparius (P<0.1). Soft-seeded L. stoechas did not germinate after gut passage. The results indicate a potential role of herbivore endozoochory for the long-distance dispersal of dry-fruited shrubs and their potential colonization of distant sites.

A Site

At Ounjougou, a site complex situated in the Yamé River valley on the Bandiagara Plateau (Dogon country, Mali), multidisciplinary research has revealed a rich archaeological and paleoenvironmental sequence used to reconstruct the history of human-environment interactions, especially during the Late Holocene (3500–300 cal BC). Geomorphological, archaeological, and archaeobotanical data coming from different sites and contexts were combined in order to elaborate a chronocultural and environmental model for this period. Bayesian analysis of 54 14C dates included within the general Late Holocene stratigraphy of Ounjougou provides better accuracy for limits of the main chronological units, as well as for some particularly important events, like the onset of agriculture in the region. The scenario that can be proposed in the current state of research shows an increasing role of anthropogenic fires from the 3rd millennium cal BC onwards, and the appearance of food production during the 2nd millennium cal BC, coupled with a distinctive cultural break. The Late Holocene sequence ends around 300 cal BC with an important sedimentary hiatus that lasts until the end of the 4th century cal AD.
