Bimodal winter haul-out patterns of adult Weddell seals (Leptonychotes weddellii) in the southern Weddell Sea

Hauling out is an essential component of pinniped life-history. Haul-out behaviour may be affected by biological (e.g. sex, age and condition) and physical factors (e.g. food availability and environmental conditions), and identifying these factors may help explain the spatio-temporal distribution and habitat use of pinnipeds. The aim of this study is to describe observed winter haul-out patterns of adult Weddell seals in the Weddell Sea and investigate the role of potential predictors to gain insight into the way these animals interact with the physical environment in this region. We examined the haul-out behaviour in relation to available biological (i.e., diving effort, sex) and physical information (i.e., sun angle). Thirty-three satellite telemetry tags were deployed on adult Weddell seals in the southern Weddell Sea during February 2007, 2009 and 2011, following their annual moult recording information on the behavioural mode of the animal: at surface, hauled out or diving. At the end of the austral summer Weddell seals spent, on average, more than 40% of their time hauled out on the ice. Under constant light conditions, it appears that physiological factors drive sex differences in the timing and duration of haul-out behaviour, with females spending on average more time hauled out than males during daylight hours. This time spent hauled-out declined to around 15% in both sexes by the beginning of autumn and remained at this level with a clear nocturnal haul-out pattern during the winter. The time spent diving increased during this period, indicating an increase in foraging effort during the winter months, and led to a common haul-out pattern in both sexes over winter. We found a positive relationship between haul-out duration and the percentage of time spent diving prior to a haul-out in both sexes, with the exception of female daytime haul-outs early in the year

Brazilian Botanic Gardens

We argue that botanic gardens, as plant conservation focused institutions, have been tested in temperate regions that possess a relatively robust conservation infrastructure and a relatively low number of threatened species. The ability of the Brazilian botanic gardens to support plant conservation is especially challenging, given their small number relative to Brazil’s plant diversity and the increasing rate of habitat loss and plant endangerment. This study, the first for Brazil, assesses the conservation capacity of Brazilian botanic gardens. An assessment is made of the status of conservation facilities in Brazilian botanic gardens and the conservation status of their plant collections.This was based on a survey sent to thirty-six Brazilian botanic gardens in 2011– 2013 using information from the 2008 Brazilian Red List, and seven state conservation lists. The results identified a small percentage of threatened species (n =102/21 per cent) in ex situ collections of 22 botanic gardens and less than 10 per cent representation for each state red list. An assessment based on the updated Brazilian Red List (2014) showed that 425 threatened species were maintained in living collections of 18 botanic gardens. Despite the extensive size of some collections, the proportion of threatened species in the collections was found to be very low. Improvement in infrastructure, technical capacity, including horticultural skills, and development of policies and protocols will benecessary to increase the effectiveness of the collections for conservation aims

Hybrid visibility compositing and masking for illustrative rendering

In this paper, we introduce a novel framework for the compositing of interactively rendered 3D layers tailored to the needs of scientific illustration. Currently, traditional scientific illustrations are produced in a series of composition stages, combining different pictorial elements using 2D digital layering. Our approach extends the layer metaphor into 3D without giving up the advantages of 2D methods. The new compositing approach allows for effects such as selective transparency, occlusion overrides, and soft depth buffering. Furthermore, we show how common manipulation techniques such as masking can be integrated into this concept. These tools behave just like in 2D, but their influence extends beyond a single viewpoint. Since the presented approach makes no assumptions about the underlying rendering algorithms, layers can be generated based on polygonal geometry, volumetric data, point-based representations, or others. Our implementation exploits current graphics hardware and permits real-time interaction and rendering.publishedVersio

DEATHS IN OPEN WATER SWIMMING RACES IN BRAZIL FROM 2009 TO 2019

International Journal of Exercise Science 15(6): 1295-1305, 2022. Since the inclusion in the Olympic Games (2008), open swimming races have attracted greater media attention and, therefore, have a greater number of practitioners, especially in Brazil, an extremely favorable country for this sport. However, increasing reports of fatal incidents in open water races brought the medical and scientific community to attention. The aim of this study was to review the characteristics of deaths in open waters events in Brazil from 2009 to 2019. The survey was divided into 3 steps: 1) contacting sports-related federations and companies, including swimming and triathlon federations, master associations and event organizing companies; 2) internet search; and 3) personal communication with athletes, coaches, organizers, and health personnel. A total of 12 deaths were observed in open water swimming races, including triathlon swimming segment races in Brazil from 2009 to 2019. The average was 1.1 deaths per year, whereas in the last 3 years (2017-2019) the average was 3 deaths per year. The male participants accounted for 11 deaths (91.7%), the average age was 47 years old, experienced athletes were more affected (80%), and incidents occurred mainly in ocean waters (75%). The increase of deaths in the last 3 years draws attention, and the best way to reduce the deaths by drowning in open waters in Brazil, is to understand the profile and causes, to propose solutions

Development of service-oriented architectures using model-driven development : a mapping study

Context: Model-Driven Development (MDD) and Service-Oriented Architecture (SOA) are two challenging research areas in software engineering. MDD is about improving software development whilst SOA is a service-based conceptual development style, therefore investigating the available proposals in the literature to use MDD when developing SOA may be insightful. However, no studies have been found with this purpose. Objective: This work aims at assessing the state of the art in MDD for SOA systems. It mainly focuses on: what are the characteristics of MDD approaches that support SOA; what types of SOA are supported; how do they handle non-functional requirements. Method: We conducted a mapping study following a rigorous protocol. We identified the representative set of venues that should be included in the study. We applied a search string over the set of selected venues. As result, 129 papers were selected and analysed (both frequency analysis and correlation analysis) with respect to the defined classification criteria derived from the research questions. Threats to validity were identified and mitigated whenever possible. Results: The analysis allows us to answer the research questions. We highlight: (1) predominance of papers from Europe and written by researchers only; (2) predominance of top-down transformation in software development activities; (3) inexistence of consolidated methods; (4) significant percentage of works without tool support; (5) SOA systems and service compositions more targeted than single services and SOA enterprise systems; (6) limited use of metamodels; (7) very limited use of NFRs; and (8) limited application in real cases. Conclusion: This mapping study does not just provide the state of the art in the topic, but also identifies several issues that deserve investigation in the future, for instance the need of methods for activities other than software development (e.g., migration) or the need of conducting more real case studies.Peer ReviewedPostprint (author's final draft
