Chestnut Red Stain (CRS) is a heartwood discoloration that widely affects Castanea sativa Mill. productive coppice stands in the northeast of Spain. At the early stages of infection, the structural properties of the wood are not affected, but still its economic value drops up to 70% due to the rejection of this wood. This disease is caused by the f...

In this work, we investigate the native parasitoid community colonising galls by an invasive pest: the oriental chestnut gall wasp (OCGW), Dryocosmus kuriphilus (Hymenoptera; Cynipidae). We tried to understand how native parasitoids react after the arrival of the pest (two‐year sampling period) in the province of Zamora (Castilla & León region, N‐W...

Castanea sativa is a high-value tree species whose stands have faced significant threats over the past century. The occurrence of one such threat, Chestnut Red Stain—a heartwood discoloration caused by the fungus Fistulina hepatica—has recently increased. This disease devalues the timber by up to 70% due to the rejection of stained wood by the indu...

Plant-to-plant and plant-soil interactions have been largely proved to be crucial for ecosystem assembly and functioning. Facilitation is an important structuring force in natural plant communities, especially in severe and disturbed environments, where tree recruitment does not often occur in open spaces, but under the protection of nurse trees or...

El hongo causante del escaldado del alcornoque Diplodia corticola se asocia al decaimiento y pérdida de productividad de los rodales de alcornoque (Quercus suber L.). La no renovación por parte de la Unión Europea de los químicos usados hasta el momento en la prevención y control del hongo ha acelerado la búsqueda de alternativas efectivas y respet...

The canker disease caused by Diplodia corticola is one of the most important emerging pathologies of cork oak (Quercus suber) in western Europe. The fungus is dispersed by borer insects, although it is also thought that the spores can be dispersed by wind and rain. The aim of this study was to evaluate the presence of airborne inoculum of D. cortic...

Mitoviruses (family Mitoviridae) are small capsid‐less RNA viruses that replicate in the mitochondria of fungi and plants. However, to date, the only authentic animal mitovirus infecting an insect was identified as Lutzomyia longipalpis mitovirus 1 (LulMV1). Public databases of transcriptomic studies from several animals may be a good source for id...

BACKGROUND Botryosphaeria canker (causal agent: Diplodia corticola) is considered one of the most important diseases of cork oak (Quercus suber) stands since it necrotizes the subero‐phellodermic layer preventing cork regeneration after harvesting. One of the most intriguing etiological issues of this disease is its plausible spreading through trun...

The effect of inoculation with Fusarium circinatum on survival of seed and seedlings of 19 populations of Pinus sylvestris was examined under environmentally controlled conditions, with four treatments (0, 50, 10 ³ , 10 ⁶ spores ml ⁻¹ ). A single seed source of P. radiata was included as a positive control. Germination (emergence of the plumule abo...

The oak pinhole borer, Platypus cylindrus F., mainly colonizes oaks (Quercus sp.), and it is considered among the most serious pests of cork oak (Quercus suber L.). Despite being traditionally considered as a secondary pest in thermophilic oak woodlands, outbreaks seem to be more frequent throughout the Mediterranean Basin thus becoming a growing f...

The factors shaping the composition of microbial communities in trees remain poorly understood. We evaluated whether the core and satellite fungal communities in five pine species (Pinus radiata, Pinus pinaster, Pinus sylvestris, Pinus nigra, and Pinus uncinata) were shaped by the host species identity. Because the trees had earlier been inoculated...

Cryphonectria parasitica (Murrill) M.E. Barr (Sordariomycetes, Valsaceae) is the causal agent of chestnut blight. This disease is a major concern for chestnut cultivation in Europe. The fungus colonizes vascular tissues and evolves generating cankers causing severe dieback and the death of the tree. Excised and debarked well-lignified shoots of 28...

Cork is a renewable resource mainly produced in Mediterranean countries thanks to sustainable management of cork oak (Quercus suber) stands. The infection caused by the ascomycete fungus Diplodia corticola promotes the occurrence of cankers that reduce cork regeneration devaluating the stands. In this article, we tested the hypothesis that the tree...

Botryosphaeria canker of Quercus suber (causal agent: Diplodia corticola) poses a major threat for cork production along the western Mediterranean Basin. Infection by D. corticola induces cankers, which reduce tree vigour and compromise phellem regeneration. European policies in forest health advise the use of environmentally friendly methods, such...

A survey of the native parasitoid community was conducted to characterize its possible use as biological control for Asian Chestnut Gall Wasp (ACGW) at two sampling sites in northern Spain. To this end, 500 ACGW galls were collected over five sampling dates between May and July 2017; 250 of them were dissected to estimate the parasitism rates and t...

The palm borer moth (Paysandisia archon, Burmeister) is a member of the Castniidae family originally from South America and is currently included in the A2 list of the OEPP/EPPO. This moth was introduced to Europe in 2000 through ornamental palms. Since its accidental introduction, it has become a major threat for natural stands of native palms, as...

Fusarium circinatum (Nirenberg and O’ Donnell) is the causal agent of pine pitch canker (PPC) disease, one of the most devastating forest diseases worldwide. Long-distance spread occurs mainly through the movement of infected seeds whereas at regional level, the movement of seedlings, substrates, or containers may play an important role in fungal d...

Dryocosmus kuriphilus is a non-native pest that has recently spread through Europe with a special incidence along the Mediterranean Basin. The presence of this exotic wasp (originally from Asia) threatens stands and orchards of sweet chestnut (Castanea sativa Mill.) as it reduces tree growth and consequently fruit production. In this study the livi...

The fungal pathogen Fusarium circinatum (Nirenberg and O’ Donnell) is the causal agent of pine pitch canker (PPC) disease, which seriously afects conifer species in forests and nurseries worldwide.

Bark beetles (Coleoptera, Scolytinae) carry a diverse filamentous fungal community sometimes acting as vectors or carriers of phytopathogens. In this study, mycobiota carried by two Tomicus species (Tomicus piniperda and Tomicus destruens) were investigated through (i) morphological and molecular identification of taxa; (ii) taxonomic richness, div...

The red-legged partridge (Alectoris rufa) is the most important gamebird in Spain. Due to population declines in recent decades, management approaches increasingly include the release of farm-reared partridges and the establishment of so-called intensive estates, where hunting is based on put-and-take partridges. The release of farm-reared partridg...

Fifteen families of mycoviruses have been described and 80% of these catalogued. However, their evolutionary relationship with fungi is not clear. The mycovirus genome can be formed by single or double-stranded RNA (ssRNA/dsRNA) or single-stranded DNA (ssDNA). The effects of mycoviruses range from the induction of a cryptic state (asymptomatic) to...

The Aquatic Warbler (Acrocephalus paludicola) is one of the most threatened migratory passerine birds in the world. The species stops over at both European and African wetlands during its migration. Using data from a long-term ringing program in the restored wetland of La Nava (Spain), we describe several aspects of the species' stopover ecology at...
