    We study biologically ‘orchestrated’ coherent quantum processes in collections of protein microtubules of brain neurons, which correlate with, and regulate, neuronal synaptic and membrane activity. In this situation the continuous Schrodinger evolution of each such process terminates in accordance with the specific Diosi-Penrose (DP) scheme of ‘objective reduction’ (‘OR’) of the quantum state. This orchestrated OR activity (‘Orch OR’) is taken to result in moments of conscious awareness and/or choice. We analyze Orch OR in light of advances and developments in quantum physics, computational neuroscience and quantum biology. Much attention is also devoted to the ‘beat frequencies’ of faster microtubule vibrations as a possible source of the observed electroencephalographic (‘EEG’) correlates of consciousness

    Исследования проводились в заповеднике «Плаюл Фагулуй» в центральной части Республики Молдова в 2011-2014 годах. В ходе исследования было зарегистрировано 26 видов мелких млекопитающих (7 видов насекомоядных и 19 видов грызунов). За все годы доминирующим видом был А. agrarius с более чем 33% из всех мелких млекопитающих, в то время как среди землероек наиболее распространенным был S. araneus. Значения индекса разнообразия Шеннона в весенний период варьировали между 0,3 и 0,85, а осенью между 0,6 и 1,1, причем самое низкое зарегистрировано в лесных экосистемах, а наибольшее во влажных биотопах. Наблюдалось общее увеличение индексов разнообразия в большинстве биотопов с начала периода исследования до 2014 года. Наибольшее сходство сообществ было зарегистрировано между обрабатываемыми полями, расположенными вблизи леса, и опушкой акациевого насаждения, а также между берегами водных бассейнов и влажными долинами. Анализ рарефакции указывает, что часть видового разнообразия еще не обнаружена. Мониторинг фауны мелких млекопитающих будет продолжаться.The studies were performed in Plaiul Fagului reserve from the central part of the Republic of Moldova during 2011-2014 years. During the study 26 species of small mammals (7 insectivore and 19 rodent species) were registered in the reserve. In all the years the dominant species was A. agrarius with more than 33% of all small mammals, while among shrews the most abundant was S. araneus. The values of Shannon diversity index in spring period were comprised between 0.3 and 0.85 and in autumn between 0.6 and 1.1, the lowest being registered in forest ecosystems and the highest in wet biotopes. A general increasing of diversity indexes in most of biotopes from the beginning of study period to the last year was established. The highest similarity was registered between cultivated land situated near the forest and edge of acacia plantation, as well as between shores of water basins and wet valleys. The rarefaction analysis indicates that a fraction of species diversity was not yet discovered. The monitoring of small mammal fauna will continue
