Reading as a Universal Activity of a Primary School Student
В статье рассмотрена сущность процесса чтения как реализация компетенции, которые связаны с передачей прочитанного текста. Автор уточняет, что при формировании сущности понятия чтения как универсальной деятельности младшего школьника необходимо учитывать объект чтения, то есть тексты, как особую категорию, которая представляет результат деятельности речевого характера, отраженный в письменном виде. Рассмотрены видовые характеристики объектов чтения как универсальной деятельности младшего школьника зависят от того является ли текст сплошным либо не сплошным.The article discusses the essence of the reading process as the implementation of competencies that are associated with the transfer of the read text. The author clarifies that when forming the essence of the concept of reading as a universal activity of a younger student, it is necessary to take into account the object of reading, that is, texts, as a special category that represents the result of a speech activity reflected in writing. The specific characteristics of reading objects as a universal activity of a junior schoolchild are considered, depending on whether the text is continuous or not continuous

Lichen response to ammonia deposition defines the footprint of a penguin rookery
Ammonia volatilized from penguin rookeries is a major nitrogen source in Antarctic coastal terrestrial ecosystems. However, the spatial extent of ammonia dispersion from rookeries and its impacts have not been quantified previously. We measured ammonia concentration in air and lichen ecophysiological response variables proximate to an Adèlie penguin rookery at Cape Hallett, northern Victoria Land. Ammonia emitted from the rookery was 15N-enriched (δ15N value +6.9) and concentrations in air ranged from 36–75 µg m−3 at the rookery centre to 0.05 µg m−3 at a distance of 15.3 km. δ15N values and rates of phosphomonoesterase (PME) activity in the lichens Usnea sphacelata and Umbilicaria decussata were strongly negatively related to distance from the rookery and PME activity was positively related to thallus N:P mass ratio. In contrast, the lichen Xanthomendoza borealis, which is largely restricted to within an area 0.5 km from the rookery perimeter, had high N, P and 15N concentrations but low PME activity suggesting that nutrient scavenging capacity is suppressed in highly eutrophicated sites. An ammonia dispersion model indicates that ammonia concentrations sufficient to significantly elevate PME activity and δ15N values (≥0.1 µg NH3 m−3) occurred over c. 40–300 km2 surrounding the rookery suggesting that penguin rookeries potentially can generate large spatial impact zones. In a general linear model NH3 concentration and lichen species identity were found to account for 72 % of variation in the putative proportion of lichen thallus N originating from penguin derived NH3. The results provide evidence of large scale impact of N transfer from a marine to an N-limited terrestrial ecosystem
Effects of nitrogen enrichment on phosphatase activity and nitrogen: phosphorus relationships in Cladonia portentosa
• Relationships between nitrogen deposition in the UK and phosphomonoesterase (PME) activity and nitrogen (N) and phosphorus (P) concentrations in Cladonia portentosa were quantified to understand factors limiting lichen growth and to further develop biomarkers for N pollution.
• Lichen was collected from sites differing either in rates of wet N (NH4+ + NO3-) deposition or in annual mean N concentration in rainfall based on both measured and modelled data sets. The PME activity, and total N and P concentrations were measured in specific horizontal strata in lichen mats and PME activity in the thallus was located using an enzyme-labelled fluorescent phosphatase substrate.
• With an increase in modelled N deposition from 4.1 to 32.8 kg N ha-1 yr-1, PME activity, thallus N and N : P ratio increased by factors of 2.3, 1.4 and 1.8, respectively. Correlations with modelled data were generally stronger than with measured data and those with N deposition were stronger than those with N concentration in rainfall. The PME activity was located solely in the lichen fungus in outer regions of the thallus.
• Nitrogen enrichment changes lichen N : P ratios from values typical of N limitation (for example, 10) to those indicative of P limitation (for example, 26) driving upregulation of PME activity
Response of phosphomonoesterase activity in the lichen Cladonia portentosa to nitrogen and phosphorus enrichment in a field manipulation experiment
• Effects of nitrogen (N) enrichment on the heathland lichen Cladonia portentosa
were quantified to test the hypothesis that modified N : phosphorus (P) relationships
observed in this species in N-polluted natural environments are a direct effect
of increased N deposition, and to evaluate potential confounding effects of N form
and P availability.
• Cladonia portentosa was harvested from experimental plots in lichen-rich peatland
vegetation (background total N deposition of 8 kg N ha)1 yr)1) treated for
4 yr with additional wet N deposition at 0, 8, 24 and 56 kg N ha)1 yr)1 as either
NH4
+ or NO3
), and with or without P added at either 0.6 or 4 kg P ha)1 yr)1.
• Nitrogen enrichment increased thallus N concentration, N : P mass ratio and
phosphomonoesterase (PME) activity by factors of up to 1.3, 1.4 and 1.7, respectively,
effects being independent of N form. Phosphomonoesterase activity was
tightly related to thallus N : P ratio with additions of P at 4 kg ha)1 yr)1 depressing
PME activity by a factor of 0.4.
• Nitrogen enrichment induces P-limitation in C. portentosa with attendant
changes in chemical and physiological characteristics that could be used as sensitive
biomarkers with which to detect low levels of N pollution
