Animal‐Mediated Dispersal and Clonal Growth Drive Prunus cerasus Invasion in Andean Temperate Forest
Integrative Zoology, EarlyView.Prunus cerasus reproduces by clonality and by seed dispersal and germination. P. cerasus is invading Patagonian protected areas. The relative relevance of germination and clonal reproduction changes along the time of P. cerasus arrival at a site. Seed dispersal by foxes is primarily responsible for the spread of P. cerasus to new areas.

Arabian Archaeology and Epigraphy, EarlyView.ABSTRACT While oasis settlements emerged during the Bronze Age in Eastern and Northern Arabia, the settlement process in Central Arabia was different. Excavations at al‐Yamāma—main ancient settlement of the al‐Kharj oasis (Riyadh Province, KSA)—suggest that the latter did not emerge before the second half of the first millennium BCE.

Agricultural and Forest Entomology, EarlyView.The persistence and health of ash populations were characterized in post‐outbreak forests near the epicentre of the emerald ash borer (EAB) invasion in North America. Regenerating ash remained abundant, but densities of understory ash were higher in wetlands (hydric), while ash remained at the seedling stage in riparian (mesic) and upland (xeric ...
