In this paper we provide a brief overview of the two mathematical constructions presented by Yves André during the first two session of Ircam’s “Mathematical School for Musicians and other Non-Mathematicians”. After discussing a musical application of Operator Theory we try to suggest the possible connection between Jean-Yves Girard’s Geometry of Interaction (based on a special case of von Neum...

By the method of biogeochemical lichen indication on territory arboretum Falz-Fein Biosphere Reserve "Askania-Nova" (Kherson Region, UKRAINE) temporal trends (2011-2021) in concentrations heavy metals and other micro- macro-elements epiphytic lichens was estimated. The samples Parmelia sulcata, Xanthoria parietina Evernia prunastri collected 2011 (39 sites) 2021 (44 for concetrations 22 chemica...

Traditionally phenology studies have been focused on changes through time, but there exist many instances in ecological research where it is necessary to interpolate among spatially stratified samples. The combined use of Geographical Information Systems (GIS) and Geostatistics can be an essential tool for spatial analysis in phenological studies. Geostatistics are a family of statistics that d...

In spite of the increasing number of studies on the importance of transgenerational plasticity for species response to novel environments, its effects on species ability to respond to climate change are still largely unexplored. We study the importance of transgenerational plasticity for response of a clonal species Festuca rubra. Individuals from four natural populations representing two level...

Fall season fertilization is a widely recommended practice for turfgrass. Fertilizer applied in the fall, however, may be subject to substantial leaching losses. A field study was conducted in Connecticut to determine the timing effects of fall fertilization on nitrate N (NO3-N) leaching, turf color, shoot density, and root mass of a 90% Kentucky bluegrass (Poa pratensis L.), 10% creeping red f...

The aim of this study was to determine the effects of N-supply and defoliation on rhizodeposition from Festuca rubra, in the context of whole-plant C- partitioning and root morphology. Plants were grown for 36 d in axenic sand microcosms continuously percolated with nutrient solutions of either high or low N concentration (2 mM or 0.01 mM NH(4)NO(3), respectively). The effects of partial defoli...
