    Description: Natural potential of the increase in abundance is identified for artemia populations, based on the analysis of «inherent rate of natural increase in abundance» (r) change. It can be considered as the quantitative assessment of the pressure degree of natural factors on artemia populations. As an example of increase in population abundance, the data are presented that were obtained for A. salina populations in 8 saline lakes of Crimea (Russian Federation). Based on the study of seasonal dynamics of artemia population abundance in the lakes, the values (r) were estimated for different time spans during the growing season. Calculations for r values for the total growing season of the populations showed that the total ratio between mortality and birthrate is negative for all lakes. It can be assumed that maximum rate of increase in abundance of natural artemia populations is determined by the ratio of their definitive weight and average weight of an individual in a population. The analysis indicated that average weight of an individual in a population of A. salina in various water bodies and in different years varied from 0.23 to 0.53 g, i.e. changed in 2.5 times. Under extreme values of Wav/Wmax, the rmp appears to be equal to 0.0187 and 0.0046, respectively. Upon comparison of two extreme options, it can be noted that the increase of Wav/Wmax in 2.5 times leads to the decrease of rmp in 4 times.
    Description: На основе анализа изменения «врожденной скорости естественного увеличения численности» (r) изучено, в какой мере в популяциях артемии реализуются природные потенции увеличения их численности. Ее можно рассматривать как количественную оценку степени давления природных факторов на популяции артемий. В качестве примера роста численности популяции были приведены данные, полученные П.М. Вороновым для популяций A. salina в 8 соленых озерах Крыма. На основе изучения сезонной динамики численности популяций артемий в озерах были рассчитаны значения (r) для отдельных отрезков времени в течение вегетационного сезона. Расчеты значений r для всего вегетационного периода популяций показали, что во всех озерах суммарное соотношение между смертностью и рождаемостью имеет отрицательный знак. Можно допустить, что максимальная скорость увеличения численности в природных популяциях артемий определяется соотношением их дефинитивного веса и средним весом особей в популяции. Анализ показал, что средний вес особи в популяции A. salina в разных водоемах и в разные годы колеблется от 0,23 до 0,53 г, т. е. изменялся в 2,5 раза. При крайних значениях Wср/Wmax величина rmp оказывается равной, соответственно, 0, 0187 и 0,0046. Сравнивая два крайних варианта, можно отметить, что при увеличении Wср/Wmax в 2,5 раза это приводит к уменьшению rmp в 4 раза.

    [Perspective] Polynitrogen chemistry enters the ring (2017)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2017-01-27
    Description: Polynitrogens have the potential for ultrahigh-performing explosives or propellants because singly or doubly bonded polynitrogens can decompose to triply bonded dinitrogen (N2) with an extraordinarily large energy release. The large energy content and relatively low activation energy toward decomposition makes the synthesis of a stable polynitrogen allotrope an extraordinary challenge. Many elements exist in different forms (allotropes)—for example, carbon can exist as graphite, diamond, buckyballs, or graphene. However, no stable neutral allotropes are known for nitrogen, and only two stable homonuclear polynitrogen ions had been isolated until now—namely, the N3− anion (1) and the N5+ cation (2). On page 374 of this issue, Zhang et al. (3) report the synthesis and characterization of the first stable salt of the cyclo-N5− anion, only the third stable homonuclear polynitrogen ion ever isolated. Author: Karl O. Christe
