Opis:: Physalis peruviana is one of the most promising tropical fruit plants because of its rapid growth, high yield, and nutritional quality. Th is study was designed to investigate plant development under heavy metal contamination (Cd, Pb) and responsiveness to arbuscular mycorrhizal fungi (AMF) colonization by Rhizophagus clarum and Claroideoglomus claroideum. Th e antioxidant capacity, total lipid content and fatty acid profi le in fruits, accumulation of Cd and Pb in diff erent plant parts, plant dry biomass, and mycorrhizal colonization were determined. As a result of inoculation, a considerable reduction in Cd and Pb in the fruits was observed, compared with non-inoculated plants. Th e fruit number and dry weight increased in plants associated with C. claroideum. Th ese plants also showed higher acid phosphatase activity, root protein accumulation and glomalin production. Th e type of antioxidant defense was AMF strain-dependent. Antioxidant activity and H2O2 neutralization were enzymatic rather than non-enzymatic processes in the fruits of C. claroideum plants compared with those forming an association with R. clarum. Mycorrhizal establishment changed the composition and concentration of fruits’ fatty acids. Th e ratio of unsaturated fatty acids was increased. With respect to the accumulation of bioactive compounds in golden berry the present fi ndings are important for obtaining the optimum benefi ts of mycorrhizal association under unfavorable conditions.

Opis:: From the Early Maastrichtian white chalk of Rügen Island (N Germany), a specimen of the echinoid Echinocorys ovata featuring 27 boring traces of the ichnogenus Caulostrepsis is described. Individual traces are shallow to moderately deep U−shaped depressions and show distinct regeneration textures evidencing a syn−vivo infestation. All traces are located on the plastron between the peristome and periproct of the host echinoid, indicating an adaptation of the trace maker by choosing the most advantageous position of the specific host. The traces are attributed to the work of boring spionid polychaetes (Polydora complex), grounded on the close morphological resemblance with initial borings of Recent polydorids. This is the first evidence for a possible association of a boring polychaete not only with an echinoid but with an echinoderm in general. The symbiotic relationship was commensalistic in nature with the spionid probably taking advantage of organic matter resuspended by the echinoids locomotion and feeding activity and benefiting from effective shelter. For the host echinoid, the association was moderately harmful. The soft bottom environment of the chalk sea provided very limited hard substrate ecospace for settlers and bioeroders, available only in form of biogenic structures. Echinocorys was a dominant component of this benthic community and can be considered as a suitable host for symbiotic interactions because of its size and assumed longevity.

Opis:: Mycorrhiza is one of the most common forms of symbiotic association between plants and fungi occurring in nature. It is formed by hyphae of a fungus with the roots of a plant. Such symbiotic associations are currently estimated to occur in approximately 75% of trees. The presented study is an attempt to enlighten multifaceted ecological aspects of the symbiosis between plants and fungi with special consideration given to the favourable effect of a fungus on the health condition and growth of a plant.
