ABSTRACT Accurate estimations of adult mortality are essential for understanding population dynamics and achieving efficient management actions that are directed toward long-lived species. Several noninvasive methods may be used to monitor endangered long-lived birds like raptors, but their performance in real-world scenarios remains poorly studied. We used eight Bonelli's Eagle (Aquila fasciata) breeding pairs (1) to compare the efficiency of direct observations with binoculars and telescopes (2004–2016), camera trapping (2012–2016), and feather genetic analysis (2004–2015) for detecting and identifying individuals over time, (2) to conduct a cost-benefit analysis of methods, and (3) to evaluate the accuracy of the direct observation method for estimating survival by comparing it with camera trapping and feather analysis. Both the feather genetic analysis and camera trapping approaches allowed us to successfully identify individuals and to detect replacements that we did not notice during direct observations. The classic direct observation method overestimated adult survival, which could hamper an accurate understanding of the demographic dynamics of this population. Feather analysis gave a low detection rate of individuals (47%), probably due to difficulties in finding feathers in the rugged habitat of this species. However, identification success at the individual level with this method was 96%. Remote camera surveys had both a high detection rate (100%) and identification success (93%). Given that costs associated with camera surveys were lower than the costs of genetic procedures, we concluded that camera trapping is the most efficient indirect method to assess adult survival in this and other raptors with external features that make individual identification possible. However, because no method showed complete efficiency, genotyping of feathers collected at the end of the breeding season could be a useful additional method, especially when camera trapping is not possible or when it fails.

ABSTRACTThis pilot project aims to test and see the relevance of the direct observation method to collect data on the barriers and facilitators to attending public places by seniors with TBI. The study is based on the conceptual framework VADA WHO which focuses on the development of friendly built and technological environments for seniors. Three elderly people participated in the study, recruited from an ongoing project, The Citizen Intervention in Community Living (APIC), in the presence of their personalized attendant. The study shows the feasibility of the method in terms of its acceptability and resources mobilized. It shows its relevance to access additional data that would have been difficult to obtain using others methods (e.g., semi-structured interview), such as the identification of the strategies used by the participants to address the obstacles encountered (avoidance, travel planning, use of physical and preventative support of the personalized attendant).

The article deals with the consideration of the paremic text in the modern linguistic paradigm: approaches to the researches are presented, the text-forming and linguocultural potential of individual units is shown. The direct observation method was used as the main method in this work, followed by the use of descriptive-analytical, comparative, contextual and linguistic and cultural methods. The Study is based on examples from lexicographic sources and illustrations from the Internet. The article provides an overview of the main aspects of the paremiological studies. Paremias are considered as a folklore genre, the thematic and ideographic principle of classifying paremias is presented, the aspects of cultural linguistics (linguoculturological) and translation studies are substantiated, and peculiarities of historical and etymological discursive (functional) analysis are shown. Comparative linguistic and cultural analysis is recognized by the authors of the paper as an integrative aspect of the paremiological material description. The article analyzes the text-forming and linguoculturological potential of the paremiology in different languages. As an example of the realization of the text-forming potential of paremias, the functioning of the proverb Не рой другому яму - сам в нее попадешь (упадешь) (He who digs a pit for others may fall himself therein) is studied as the verbal part of the Russian and Lithuanian demotivators. The paper provides a linguistic and cultural analysis of paremias with a toponymical component in different languages. Despite the abundance of various toponyms, which are characteristic for different countries, in these proverbs are dominated the international component, which is associated with the universal laws of human thinking, which makes it possible to find their semantic equivalents in various languages. The relevance of this study lies in the fact that paremias are considered in various aspects from the standpoint of modern humanistic education. With the development of social communications in modern society, an intercultural connection is being strengthened, requiring linguocultural commentary.

The spatial patterns of field arthropod communities are an essential part of ecology and can provide fundamental data regarding field ecological processes and reveal the mechanism of ecosystem biodiversity maintenance. This study investigated the spatial distribution pattern of field insect communities to detect the spatial relationships between insect communities in farmland. The study site was located at the Dehui Agro-ecological Experimental Station of Black Soil, Jilin, China. Insect communities and environmental factors were sampled at 121 uniformly distributed points in a 400 × 400 m plot in August, September, and October 2015. The analysis revealed that insect communities from June to October demonstrated significant spatial correlation, and 6085 samples of 47 species and 47 families in 11 orders were collected from the insect community in the farmland. The farmland insect community structure changes and dynamic changes of nutritional function groups occur with time. According to the 400 x 400 m plot, the diversity of farmland insect communities and functional groups is maintained at a relatively high and stable level. In this study, a total of 6085 samples of corn farmland insects were obtained using the fluke method and direct observation method, including 11 orders, 26 families and 47 species, 4 absolute dominant populations, 6 main dominant populations, and 37 other populations. These studies can provide help for pest control in the spring corn area of Northeast China.

Camera trapping is widely used in different ecological studies and is particularly important for remote locations and extreme environments. However, the application of camera traps in Arctic regions remains very limited. One of the challenges is the formation of hoar on the lens of cameras. In this article, we propose a solution to address this problem by changing the camera parameters and its position in order to optimize the camera trap for long-term subnivean deployment in the Canadian Arctic. Preliminary field tests show that this approach allows tracking lemmings in the frozen environment without natural light or external electrical power supply, where the direct observations are impossible for the most part of the year. We obtained the first videos of lemmings under the snow during the Arctic winter. Extending the observational network of the newly designed camera traps will help to better understand lemming population dynamics. The demonstrated approach is also promising for other polar applications.

  Rice farmers in Besur Village planted four species of refugia plants around rice plants to enhance biological control as a part of Healthy Plant Management Program. These refugia plants were flowering plants i.e., Cosmos sulphureus, Helianthus annuus, Zinnia elegans, and Sesamum indicum. The objective of this research was to observe the Arthropods associating with these refugia plants. This research was conducted in December 2017 to March 2018 at Besur Village, Lamongan District, East Java Province. Samples were obtained from each refugia species by branches beating, sweep net, pitfall trap, and direct observation method in the vegetative, generative, and postharvest periods paddy plant. The results showed that Arthropods associated with refugia plants are mostly belong to the order of Diptera, Hymenoptera, and Araneae. Detritivore group was the most abundant in all periods. Analysis of the diversity and similarity of all refugia species showed moderate to high values with high similarities each other.   Keywords: beneficial insect, flower, healthy plant management, integrated pest management, paddy field
