Dieback and Replacement of Riparian Trees May Impact Stream Ecosystem Functioning Open
Alders are nitrogen (N)-fixing riparian trees that promote leaf litter decomposition in streams through their high-nutrient leaf litter inputs. While alders are widespread across Europe, their populations are at risk due to infection by th…

Alteration of the tree–soil microbial system triggers a feedback loop that boosts holm oak decline Open
In anthropic savanna ecosystems from the Iberian Peninsula (i.e. dehesa), complex interactions between climate change, pathogen outbreaks and human land use are presumed to be behind the observed increase in holm oak decline. These environ…

Screening of Cork Oak for Resistance to Phytophthora cinnamomi and Micropropagation of Tolerant Seedlings Open
Massive propagation of cork oak (Quercus suber) individuals tolerant to Phytophthora cinnamomi (Pc) is probably the most important challenge for cork production. Screening for resistance to Pc of ca. 200 seedlings obtained from a single co…

Warming Scenarios and Phytophthora cinnamomi Infection in Chestnut (Castanea sativa Mill.) Open
The main threats to chestnut in Europe are climate change and emerging pathogens. Although many works have separately addressed the impacts on chestnut of elevated temperatures and Phytophthora cinnamomi Rands (Pc) infection, none have stu…

Heat stress and recovery effects on the physiology and biochemistry of Castanea sativa Mill. Open
Chestnut forests are undergoing increasing heat stress due to the current global warming, but little is known about the physiology and biochemistry responses of Castanea sativa Mill. to heat or whether differences exist between populations…

Effect of grafting on phenology, susceptibility to Phytophthora cinnamomi and hormone profile of chestnut Open
Ink disease caused by the root-rot pathogen P. cinnamomi (Pc) threatens European sweet chestnut (Castanea sativa Mill.) orchards, and growers increasingly graft susceptible C. sativa traditional varieties on Pc-resistant hybrid commercial …

Severe dieback and mortality of wild olive trees associated with <i>Phytophthora</i> species in Italy Open
Wild olive (Olea europaea var. sylvestris) is a sclerophyllous drought-tolerant tree native to the Mediterranean basin, which is used as a hardy and disease-resistant rootstock on which scions of cultivated olive varieties are grafted (Bre…

Exploring the Use of Solid Biofertilisers to Mitigate the Effects of Phytophthora Oak Root Disease Open
Oak forests are facing multiple threats due to global change, with the introduction and expansion of invasive pathogens as one of the most detrimental. Here, we evaluated the use of soil biological fertiliser Biohumin® to improve the respo…

Beneficial and pathogenic plant‐microbe interactions during flooding stress Open
The number and intensity of flood events will likely increase in the future, raising the risk of flooding stress in terrestrial plants. Understanding flood effects on plant physiology and plant‐associated microbes is key to alleviate flood…

Holm oak decline is determined by shifts in fine root phenotypic plasticity in response to belowground stress Open
Summary Climate change and pathogen outbreaks are the two major causes of decline in Mediterranean holm oak trees ( Quercus ilex L. subsp. ballota (Desf.) Samp.). Crown‐level changes in response to these stressful conditions have been wide…

Invasive forest pathogens affect the characteristics, microbial colonisation, and decomposition of leaf litter in streams Open
Invasive tree pathogens threaten forests worldwide, but their effects on streams are poorly understood. Nevertheless, tree infections that lead to changes in the characteristics of litter inputs to streams may affect stream communities and…
