Ecosistema de información relacionado con el monitoreo del estilo de vida saludable de los adultos

This article discusses the problem of providing adults with reliable, relevant and timely information that allows them to organize their activities: the regime of work and rest in accordance with the goals of a healthy lifestyle and health correction. The goal is to determine the criteria and components of an information resource that will be adequate to the goals of keeping health of adults. The leading approaches to the health care mass media research are: structural-analytical, personality-oriented and cultural approaches. Research methods: analysis and synthesis of scientific and methodological literature and the information environment on the problems of the population health improving and methods of mathematical data processing. The article presents the results of determining the criteria for monitoring the information ecosystem on a healthy lifestyle, among these criteria the following were identified: the scientific validity of information, targeting, social significance and dialogue. Also, data portals that contribute to the solution of certain tasks of the adult population health improving were identified. The authors designed and implemented the informational and educational portal “3 youth” which is aimed at the integrated implementation of the basic health-improving needs of the adult population, taking into account the interconnection of health components: physical, mental, social. The results proving the effectiveness of using the authors' portal to ensure a healthy lifestyle for adults are presented and discussed. The article will be useful to adults who want to lead a healthy lifestyle with the support of the information resources, teachers and trainers working with people of mature age. This article is also useful for teachers of the Faculty of Physical Education who plan to promote a healthy lifestyle among different age categories.Este artículo analiza el problema de proporcionar a los adultos información confiable, relevante y oportuna que les permita organizar sus actividades: el régimen de trabajo y descanso de acuerdo con los objetivos de un estilo de vida saludable y la corrección de la salud.

Arctic introgression and chromatin regulation facilitated rapid Qinghai-Tibet Plateau colonization by an avian predator

The Qinghai-Tibet Plateau (QTP), possesses a climate as cold as that of the Arctic, and also presents uniquely low oxygen concentrations and intense ultraviolet (UV) radiation. QTP animals have adapted to these extreme conditions, but whether they obtained genetic variations from the Arctic during cold adaptation, and how genomic mutations in non-coding regions regulate gene expression under hypoxia and intense UV environment, remain largely unknown. Here, we assemble a high-quality saker falcon genome and resequence populations across Eurasia. We identify female-biased hybridization with Arctic gyrfalcons in the last glacial maximum, that endowed eastern sakers with alleles conveying larger body size and changes in fat metabolism, predisposing their QTP cold adaptation. We discover that QTP hypoxia and UV adaptations mainly involve independent changes in non-coding genomic variants. Our study highlights key roles of gene flow from Arctic relatives during QTP hypothermia adaptation, and cis-regulatory elements during hypoxic response and UV protection

Biological Earth observation with animal sensors

Space-based tracking technology using low-cost miniature tags is now delivering data on fine-scale animal movement at near-global scale. Linked with remotely sensed environmental data, this offers a biological lens on habitat integrity and connectivity for conservation and human health; a global network of animal sentinels of environmen-tal change

Flexibility in a changing arctic food web: Can rough-legged buzzards cope with changing small rodent communities?

Indirect effects of climate change are often mediated by trophic interactions and consequences for individual species depend on how they are tied into the local food web. Here we show how the response of demographic rates of an arctic bird of prey to fluctuations in small rodent abundance changed when small rodent community composition and dynamics changed, possibly under the effect of climate warming. We observed the breeding biology of rough‐legged buzzards (Buteo lagopus) at the Erkuta Tundra Monitoring Site in southern Yamal, low arctic Russia, for 19 years (1999–2017). At the same time, data on small rodent abundance were collected and information on buzzard diet was obtained from pellet dissection. The small rodent community experienced a shift from high‐amplitude cycles to dampened fluctuations paralleled with a change in species composition toward less lemmings and more voles. Buzzards clearly preferred lemmings as prey. Breeding density of buzzards was positively related to small rodent abundance, but the shift in small rodent community lead to lower numbers relative to small rodent abundance. At the same time, after the change in small rodent community, the average number of fledglings was higher relative to small rodent abundance than earlier. These results suggest that the buzzard population adapted to a certain degree to the changes in the major resource, although at the same time density declined. The documented flexibility in the short‐term response of demographic rates to changes in structure and dynamics of key food web components make it difficult to predict how complex food webs will be transformed in a warmer Arctic. The degree of plasticity of functional responses is indeed likely to vary between species and between regions, depending also on the local food web context
