New data on 10 adventive plant species are given. Two and one subspecies (Atriplex hortensis, Solanum nigrum subsp. schultesii, Nepeta cataria) new for the Republic of Buryatia. Five two interspecies hybrids (Arctium × mixtum, Galinsoga parviflora, Hesperis pycnotricha, Lactuca serriola, Medicago varia, Onobrychis viciifolia, Viola tricolor) recorded first time in Ulan-Ude city its neighborhood.

In 2021, the author observed and collected Onobrychis caput-galli (L.) Lam., a species of Fabacee previously unknown to Portuguese vascular flora, according Checklist Flora (Sequeira et al., 2011). The was found in Algarve, very restricted area, with several sites occurrence, most which sharing similar habitat conditions. All evidence suggests that is native Portugal should be added flora.

genus onobrychis is an important forage crop consisting of approximately 130 annual and perennial species. the present research focused on the cytological studies of embryogenic (e) and non-embryogenic (ne) callus as well as root meristem cells of in vitro and in vivo grown plants. on the contrary to the previous studies, a diploid viciifolia variety with 2n= 2x= 16 chromosomes was observed for...

bstract. The fish leech Johanssonia arctica (Johansson, 1898) was collected from king crabs Paralithodes camtschaticus Tilesius, 1815) in Finnmark, N Norway, and allowed to feed on experimental fish hosts in the laboratory. This leech ingested lood from laboratory-reared cod (Gadus morhua) and halibut (Hippoglossus hippoglossus). Some experimental halibut acquired rypanosome infection, with par...

A method of fundamental solutions has been used to study adiabatic transition amplitudes in two energy level systems for a class of Hamiltonians allowing some simplifications of Stokes graphs corresponding to such transitions. It has been shown that for simplest such cases the amplitudes take the Nikitin Umanski form but for more complicated ones they are formed by a sum of terms strictly relat...
