Coral reefs are quite diverse ecosystems that carry out several ecological functions and plays a relevant socioeconomic role. The artisan fishing of octopi (Octopus spp.) is practiced for the survival of part of the inhabitants of Coroa Vermelha community, in the south of the state of Bahia. We intended to study the knowledge of the octopi fishermen of Coroa Vermelha using the comprehensive ethnoecological proposal of Marques. The data were collected between July, 2006 and April, 2008 through direct observation and from interviews with fishermen met by chance and through the "native specialists" criterion. Twenty semi-structured interviews were carried out following an itinerary of pre-established questions about the activity of octopi capture, and the biological and ecological aspects of the resource. The data showed that the fishermen have knowledge about biological and ecological aspects of the octopi. Two capture techniques are used: octopus fishing (polvejamento) in the reefs and through diving. Two specific folk are recognized: the "normal octopus" (Octopus insularis) and the "east octopus" (Octopus macropus (?)). The intervieews demonstrated ecological knowledge sometimes compatible with the scientific literature, mainly in which concerns the trophic ecology and behavior of the octopi.

Abstract Background The capture of ornamental fish is one of the main economic activities of riverine families in the Amazon. However, studies regarding the local ecological knowledge of workers in this activity are still incipient. In view of this, we have studied and explored the local ecological knowledge of artisanal fishers who specialize in the capture of fish for the aquarium trade in the middle part of the Negro River basin and investigated issues related to the ecological aspects of the fish species that are targeted by this trade in the region. Methods Therefore, we conducted semi-structured interviews and applied questionnaires to artisanal fishers of ornamental fish (N = 89), from the municipality of Barcelos, from January to April 2016. Results In total, 41 popular names were cited, which correspond to four ethnocategories and 10 families. The main species were Paracheirodon axelrodi (12.5%), Hemigrammus bleheri (8.3%), Ancistrus dolichopterus (6.4%), Symphysodon discus (5.3%), and Potamotrygon motoro (3.8%). According to the fishers, the species of fish known in the region as “piabas” have a preference for living in clusters (28.9%) and carry out migratory movements (26.1%). The diet of local fish species reported by fisheries is diverse, though mainly based on periphyton (42.2%), and the reproductive cycle directly influenced by the period of flooding of rivers in the region (37.6%) Conclusion Our study revealed that the fishers possess information on the ecological aspects of local ornamental fish species, many of which are consistent with scientific literature. The information presented may assist in the decision-making process for the management of local fishery resources and contribute to the resumption of growth and sustainability in the capture of ornamental fish.

Abstract The Negro river basin is considered the largest area of extractive of ornamental fish in Brazil. This area has fundamental importance for the populations from the Amazon. The present study aimed to describe socioeconomic profile of ornamental fishermen known as “piabeiros” in the Municipality of Barcelos, as well as the ornamental fishery, fisheries area, target species, environments, fishing techniques, equipment, capture techniques and main difficulties faced by the current activity. This study was carried out in municipality of Barcelos, through semi - structured interviews, with artisanal ornamental fishermen (N= 89). The main families of ornamental fish caught and traded were: Characidae, Lebiasinidae, Gasteropelecidae, Cichilidae, Anostomidae, Loricaridae, Potamotrygonidae and Gymnotidae. The main catchment areas were igarapés, lakes, flooded fields, beaches, river banks and igapó forest. Rapiché was the most used equipment in the fisheries both by the fishermen of the urban areas (43.81%) and rural (41.89%). Most of the fishermen are associated with the colony of fishermen of Barcelos (Z33). The data showed that the dynamics of ornamental fishing have changed in a short time and directly affected fishermen, in addition to the low age renewal with the participation of younger fishermen, threatening the transmission of ecological knowledge to future generations. As a result, the increase of the problems related to the productive chain and absence of public power to the activity, since ornamental fishing has already been treated as one of the main economic activities more important for the local communities and for the State of Amazonas.

Increasing evidence suggests that coral reefs exposed to elevated turbidity may be more resilient to climate change impacts and serve as an important conservation hotspot. However, logistical difficulties in studying turbid environments have led to poor representation of these reef types within the scientific literature, with studies using different methods and definitions to characterize turbid reefs. Here we review the geological origins and growth histories of turbid reefs from the Holocene (past), their current ecological and environmental states (present), and their potential responses and resilience to increasing local and global pressures (future). We classify turbid reefs using new descriptors based on their turbidity regime (persistent, fluctuating, transitional) and sources of sediment input (natural versus anthropogenic). Further, by comparing the composition, function and resilience of two of the most studied turbid reefs, Paluma Shoals Reef Complex, Australia (natural turbidity) and Singapore reefs (anthropogenic turbidity), we found them to be two distinct types of turbid reefs with different conservation status. As the geographic range of turbid reefs is expected to increase due to local and global stressors, improving our understanding of their responses to environmental change will be central to global coral reef conservation efforts.

Coastal communities are increasingly vulnerable to climate change and its effects may push coastal ecosystems to undergo irreversible changes. This is especially true for shorebirds with the loss of biodiversity and resource-rich habitats to rest, refuel, and breed. To protect these species, it is critical to conduct research related to nature-based Solutions (NbS). Through a scoping review of scientific literature, this paper initially identified 85 articles with various ecosystem-based adaptation (EbA) strategies that could help conserve shorebird populations and promote ecotourism. Of these 85 articles, 28 articles had EbA strategies that were examined, with some like coral reefs and mangroves eliminated as they were inappropriate for this region. The scoping review identified four major EbA strategies for the Greater Niagara Region with living shorelines and beach nourishment being the most suitable, especially when combined. These strategies were then evaluated against the eight core principles of nature-based solutions protecting shorebird as well as human wellbeing. Living shoreline strategy was the only one that met all eight NbS principles. As the coastline of the region greatly varies in substrate and development, further research will be needed to decide which EbA strategies would be appropriate for each specific area to ensure their efficacy.

The study is devoted to the analysis of research texts of the historiographic development of the history of entrepreneurship in pre-revolutionary Siberia. Modern historiography has accumulated a great deal of factual material. Historians have published monographs, thematic collections, articles, abstracts, reviews, reports, bibliographic indexes, encyclopedias and reference pub-lications, the councils defend candidate and doctoral dissertations on various problems in this area. The genre variety of scientific literature about business people reflects a broad professional and public interest in trade and other business activities and contributes to the coordination of research activities. Domestic historiography of the history of merchants and entrepreneurship in Siberia is represented by a significant number of works by historians of the region. The purpose of the study is to analyze the research text as a form of organizing speech material in the scientific discourse of studying the history of entrepreneurship in Siberia in the second half of the 19th – early 20th centuries. We use the methods of historical research, based on the analysis and generalization of research by other researchers, with the application of the principle of historicism, which made it possible to apply the historical-logical, historical-systemic methods. The region-oriented approach made it possible to study more fully the features of scientific texts in the historiography of the history of entrepreneurship in Siberia. The research results are as follows: scientific historical discourse is characterized by a certain set of norms, stereotypes of thinking and behavior; scientific communication plays a significant role in the life of society; genres act as a means of organizing and formalizing interaction in the scientific community; text as a form of organizing speech material in scientific discourse is characterized by the originality and recognizability of style, compositional structure.

Goliath Grouper

The goliath grouper Epinephelus itajara is a large sized (> 400 kg) and critically endangered marine fish, which is protected in many countries, including Brazil. Through the application of semi-structured interviews, we investigated the local ecological knowledge of seven fishermen specialist on catching E. itajara from the Babitonga bay, Santa Catarina, Brazil. Local long-line fisheries for E. itajara seemed to be a disappearing tradition in the studied site, with a detailed inherent local ecological knowledge system, which is also being lost. Our study also showed that fishermen engaged in recent fisheries, such as spear-fishing, can also possess a detailed local ecological knowledge system. Through the analysis of fishermen local ecological knowledge, several aspects of E. itajara life history were registered. This species is found in the inner and outer Babitonga bay, from saline waters to areas with a large input of freshwater, and inhabits submerged wooden substrates and artificial reefs such as shipwrecks, mooring pillars and cargo containers. It is known to spawn in December and subsequent summer months in the studied area. Spawning aggregations are usually seen in December (during full moon), being also eventually observed in January and February by our informants. While lobsters, spadefishes and octopuses seem to constitute the most important food items of inner bay E. itajara, outer bay individuals may feed on catfishes, crustaceans and other fish species. The goliath grouper is regarded as pacific and curious fish, but frequently display agonistic behavior in the presence of divers. Based on the perception of well experienced spear fishermen, we hypothesize that E. itajara undertakes seasonal migrations from the inner to the outer bay during summer, and that the studied population is suffering from growth over-fishing. Our data provides a practical evidence of how joining scientific and local ecological knowledge will likely benefit E. itajara local conservation and management practices by adding important new biological data into the decision-making process.

ABSTRACTObjectives:Prion diseases are rare dementias that most commonly occur sporadically, but can be inherited or acquired, and for which there is no cure. We sought to understand which prion disease symptoms are most problematic for carers, to inform the development of outcome measures.Design:Self-completed questionnaire with follow-up of a subset of participants by structured interview.Setting:A nested study in the UK National Prion Monitoring Cohort, a longitudinal observational study.Participants and measurements:71 carers, of people with different prion diseases with a wide range of disease severity, identified 236 of their four most problematic symptoms by questionnaire which were grouped into ten domains. Structured interviews were then done to qualitatively explore these experiences. Eleven family carers of people with prion disease were selected, including those representative of a range of demographics and disease subtypes and those who cared for people with prion disease, living or recently deceased. Interviews were transcribed and formally studied.Results:The six most problematic symptom domains were: mobility and coordination; mood and behavior; personal care and continence; eating and swallowing; communication; and cognition and memory. The prevalence of these symptoms varied significantly by disease stage and type. A formal analysis of structured interviews to explore these domains is reported.Conclusions:We make suggestions about how healthcare professionals can focus their support for people with prion disease. Clinical trials that aim to generate evidence regarding therapies that might confer meaningful benefits to carers should consider including outcome measures that monitor the symptomatic domains we have identified as problematic.

The Patagoniansteppe is a cultural landscape which is constantly being recreated by man. In this case study, peridomestic forestation oftree species was analysed in a small community, including the richness of plants used and the reasons behind their choice.In the Mapuche population of Pilkiniyeu del Limay (Río Negro) free and semi-structured interviews were carried out with28 interviewees. The data was analysed using both uni- and multivariate methods. Results indicate that nine exotic speciesare used. These forested areas, used for meetings and recreation, provide useful living space and are of great socialimportance. The principal motivation behind this forestation is the need for materials for building fences (96%), toprovide shelter from the elements (86%), firewood (43%), and cattle fodder (11%). The MSD revealed a shared valuesystem with respect to the forestation. The traditional ecological knowledge that people use in the selection and use offirewood species does not seem to have an influence on choices made when planting trees around their homes. This couldindicate that forestation is a general practice deeply rooted and influenced by the oblique transmission carried out byexternal agriculture agents who visit and offer help to this community.

Researchers' interest in consumer religiosity and behavior is explained by the fact that religion influences not only the social behavior of individuals, but also their consumption behavior. Most of the studies on the subject come from Western and Asian countries with a few of such studies been conducted in Africa and particularly in Ghana. The aim of this paper is to explore the concepts of religiosity and consumer behavior in Ghana, in order to consider the role of culture in the management and marketing of industrial products. Ghana is a country where religion plays an important role in shaping lives and ensuring community cohesion. However, a determined part of the believers contributes to increasing the consumption of industrial beverages, and the obliviousness in the marketing sector also seems to be a barrier that slows the production and consumption of non-alcoholic industrial beverages. The research approach is exploratory and qualitative. The collection of qualitative data is done with the aid of a SONY voice recorder through some semi-structured interviews. Then, the qualitative data are transcribed manually and verbatim analyzed. The results show that in the context of Ghana, religiosity of believers affects the behavior of the consumer and that consumer behavior towards non-alcoholic industrial beverages affects religiosity. Keywords: Religiosity, Consumer Behavior, Industrial Beverages, Consumption, Marketing, Ghana.

The study aims to investigate the relationship between Board capital and internationalization of SMEs. The study implements a systematic review and synthesis of scientific literature. The article presents useful insights into the concept of Board capital, Agency, Resource dependency, Institutional theories, and Resource-Based view. These theories give us a better understanding of Board capital, the firm’s management and behavior. The analysis of recent studies suggests that external members of the Board might positively affect internationalization outcomes and be useful in overcoming obstacles during the initiation of international activities. Nevertheless, international entrepreneurship literature is still lacking studies considering Board capital. A deeper investigation of Board capital factors impacting the internationalization of SMEs can be stated as a future research direction.
