We describe a novel species Cheiracanthium ilicis sp. n. (Araneae, Eutichuridae) collected in the province of Toledo (Central Spain). It was found during a systematic sampling campaign carried out in an agricultural landscape with isolated Holm oaks Quercus ilex and small forest patches. Its morphology and affinities with other species of the genus are discussed. Furthermore, one mitochondrial ...

A newly recognized, late-season leaf disease of Quercus macrocarpa (bur oak) has become increasingly severe across Iowa and in neighboring states since the 1990s. Vein necrosis and leaf death may occur over the whole crown or only on the lower branches. Symptoms typically intensify year-to-year in individual trees, and there appears to be substantial variation in susceptibility. Distinctive con...

Cell polarization is a crucial process during plant development, as well as in plant-microbe interactions, and is frequently associated with extensive cytoskeletal rearrangements. In interactions of plants with inappropriate fungal pathogens (so-called non-host interactions), the actin cytoskeleton is thought to contribute to the establishment of effective barriers at the cell periphery against...

Some unusual specimens of the wood-inhabiting fungus Auricularia auricula-judae have been studied using morphological and molecular methods. As expected from external features, we describe a new species cerrina sp. nov. Sequencing ITS region confirms differences other Auricularia, preliminary phylogenetic analysis is presented. characterized by blackish fruitbodies in fresh conditions with comb...

Preliminary data from newly excavated archaeological site no. 8 in Kraków-Górka Narodowa (southern Poland) show that two main phases of Early Neolithic occupation can be distinguished based on pottery finds, one associated with the Malice culture and other Pleszów- Modlnica group Lengyel culture. These are presented along lithic materials discussed context results archaeobotanical analysis. Cha...

Aphid species within the genus Tuberculatus exhibit a variety of interactions with ants, ranging from close associations to non-attendance. An ant-attended species, Tuberculatus quercicola, and two non-attended species, Tuberculatus japonicus and Tuberculatus paiki, are sympatric and hosted by the tree species Quercus dentata (Fagaceae). An undescribed ant-attended species of Tuberculatus (sp. ...

Several squirrel species excise the embryo of acorns of most white oak species to arrest germination for long-term storage. However, it is not clear how these acorns counter embryo excision and survive in the arms race of coevolution. In this study, we simulated the embryo excision behavior of squirrels by removing 4 mm of cotyledon from the apical end of white oak acorns differing in embryo de...
