“…Moreover, these values are consistent with what can be found for other tree species of the Mediterranean area (e.g. Campelo et al, 2007;Campelo et al, 2010;Cherubini et al, 2003;Garfì, 1997;Lebourgeois et al, 2012;Touchan et al, 2014).…”

“…A similar response towards late spring-early summer precipitation and/or drought has also been found in Z. sicula and numerous other species growing in the Mediterranean (e.g. Campelo et al, 2009;Cherubini et al, 2003;Di Filippo et al, 2010;Garfì, 1997;Lebourgeois et al, 2012;Nijland et al, 2011;Tessier et al, 1994;Touchan et al, 2014). No study has been carried out so far to investigate the precise period in which Mediterranean Zelkova species form tree-rings and their relationship with precipitation.…”

“…This differs with other deciduous species of the Mediterranean which show positive signals towards winter precipitation (e.g. for Quercus species: Camarero et al, 2016;Cherubini et al, 2003;Corcuera et al, 2004;Di Filippo et al, 2010). Quercus species are known to have roots that reach deep into the ground and may attain profound water reserves (Cherubini et al, 2003) and thus make use of deeply infiltrated winter precipitation.…”

Similarly to Z. abelicea, Garfì (1997) found no relationships between winter conditions and Z. sicula tree-ring widths in Sicily except for a positive correlation with precipitation occurring shortly before growth resumption.…”

“…Furthermore, other studies have shown that broadleaved trees growing in a Mediterranean climate have reduced cambial activity during the dry and hot summer (e.g. Akkemik et al, 2006;Cherubini et al, 2003;Di Filippo et al, 2010).…”

• We established the first ever centennial chronology for a broadleaved tree on Crete.• Zelkova abelicea is most sensitive to precipitation and drought in May-June.• No growth change can be related to the increase in dry conditions of the past decades.• Z. abelicea has a high capacity to withstand changing environmental conditions.We investigate the sensitivity of the relict, endemic Cretan tree species Zelkova abelicea (Lam.) Boiss. (Ulmaceae) to several climate variables (temperature, precipitation and drought). For this purpose, we establish the first centennial tree-ring chronology for the species, and the first ever tree-ring chronology for a broadleaved species on Crete. We demonstrate the strong sensitivity of Z. abelicea towards precipitation and drought in late spring to early summer and the absence of a significant response to abundant precipitation occurring during winter or early spring. Whereas the late spring sensitivity is strong and consistent through time, the species seems to be experiencing a loss of signal towards early summer conditions since the 1970s, interpreted as an earlier cessation of cambial activity due to the increase in summer drought conditions on Crete. However, despite a reduced vegetative period, no significant decrease in radial growth of Z. abelicea was observed in the tree-ring series for the last decades, thus highlighting the capacity of Z. abelicea to withstand changing environmental conditions.

Groundwater controls on biogeomorphic succession and river channel morphodynamics

Biogeomorphic succession describes feedbacks between vegetation succession and fluvial processes that, at the decadal timescale, lead to a transition from bare river‐deposited sediment to fully developed riparian forest. Where the rate of stabilization by biogeomorphic succession is greater than the rate of ecological disturbance by fluvial processes, a river is likely to evolve into less dynamic states. While river research has frequently considered the physical dimensions of morphodynamics, less is known about physical controls on succession rates, and how these impact stream morphodynamics. Here we test the hypothesis that groundwater dynamics influence morphodynamics via the rate of biogeomorphic succession. We applied historic imagery analysis in combination with dendroecological methods for willows growing on young gravelly fluvial landforms along a steep groundwater‐depth gradient. We determined the following: floodplain morphodynamics and plant encroachment at the decadal scale, pioneer willow growth rates, and their relationships to hydrological variables. Willow growth rates were correlated with moisture availability (groundwater, discharge, and precipitation variability) in the downwelling reach, while little correlation was found in the upwelling reach. After a reduction in ecological disturbance frequency, data suggest that where groundwater is upwelling, biogeomorphic succession is fast, the engineering effect of vegetation is quickly established, and hence channel stability increased and active channel width reduces. Where groundwater is downwelling, deeper and more variable, biogeomorphic succession is slower, the engineering effect is reduced, and a wider active width is maintained. Thus, groundwater is an important control on biogeomorphic feedbacks intensity and, through the stabilizing effect of vegetation, may drive long‐term river channel morphodynamics.
