Missing Data in Sea Turtle Population Monitoring: A Bayesian Statistical Framework Accounting for Incomplete Sampling

This is the final version. Available on open access from Frontiers Media via the DOI in this recordData Availability Statement: Raw nest beach monitoring data gathered at sites outside of the national park will be made available upon request to the board of Renatura Congo ([email protected]). Raw nest beach monitoring data gathered at sites inside Conkouati-Douli National Park and code to run models are available from the Dryad Digital Repository: doi:10.5061/dryad.prr4xgxp3Monitoring how populations respond to sustained conservation measures is essential to detect changes in their population status and determine the effectiveness of any interventions. In the case of sea turtles, their populations are difficult to assess because of their complicated life histories. Ground-derived clutch counts are most often used as an index of population size for sea turtles; however, data are often incomplete with varying sampling intensity within and among sites and seasons. To address these issues, we: (1) develop a Bayesian statistical modelling framework that can be used to account for sampling uncertainties in a robust probabilistic manner within a given site and season; and (2) apply this to a previously unpublished long-term sea turtle dataset (n = 17 years) collated for the Republic of the Congo, which hosts two sympatrically nesting species of sea turtle (leatherback turtle [Dermochelys coriacea] and olive ridley turtle [Lepidochelys olivacea]). The results of this analysis suggest that leatherback turtle nesting levels dropped initially and then settled into quasi-cyclical levels of interannual variability, with an average of 573 (mean, 95% prediction interval: 554–626) clutches laid annually between 2012 and 2017. In contrast, nesting abundance for olive ridley turtles has increased more recently, with an average of 1,087 (mean, 95% prediction interval: 1,057–1,153) clutches laid annually between 2012 and 2017. These findings highlight the regional and global importance of this rookery with the Republic of the Congo, hosting the second largest documented populations of olive ridley and the third largest for leatherback turtles in Central Africa; and the fourth largest non-arribada olive ridley rookery globally. Furthermore, whilst the results show that Congo’s single marine and coastal national park provides protection for over half of sea turtle clutches laid in the country, there is scope for further protection along the coast. Although large parts of the African coastline remain to be adequately monitored, the modelling approach used here will be invaluable to inform future status assessments for sea turtles given that most datasets are temporally and spatially fragmented.Darwin InitiativeDepartment for Environment, Food and Rural Affairs (Defra)Research Englan

Do livro A montanha mágica ao filme Rumo à vida: a obra político-sanitária promovida por Bissaya Barreto e os seus sanatórios antituberculosos

Este texto visa colocar em relação três planos distintos, mas complementares: os edifícios antituberculosos construídos, na década de 1930, na região de Coimbra; o livro A Montanha Mágica, publicado por Thomas Mann, em 1924, exemplo definidor do ambiente dos sanatórios enquanto espaço de conversão física e espiritual, e o filme promocional Rumo à Vida, de 1950, divulgador da obra promovida por Bissaya Barreto. Através de uma análise que se foca nos seus pontos de contacto, busca-se sintetizar alguns dos paralelismos de uma narrativa literária, cinematográfica e arquitetónica, que tem como cenário as estruturas sanatoriais

La cronología del grupo Peninj, al oeste del lago Natrón (Tanzania): revisión de las discordias bioestratigráficas

En este trabajo se exponen los distintos resultados obtenidos para datar las formaciones sedimentarias fosilíferas del grupo Peninj. Se subraya la convergencia de los análisis de K-Ar y de los estudios paleomagnéticos y de la microfauna. Además se revisan las discordancias proporcionadas del estudio de la macrofauna, que se explican por haber tenido como marco comparativo la secuencia bioestratigráfica de Olduvai. Tras poner de relieve la necesidad de ampliar dicho marco con la inclusión de otras zonas, teniendo en cuenta el contexto paleoecológico, se revisa la biozonación estratigráfica de Peninj, comparándola con la de Koobi Fora, obteniendo resultados similares a los proporcionados por los otros tipos de análisis = In this paper the main results obtained for dating the fossiliferous formations of the Peninj Group are exposed. The similar results drawn from the K-Ar analysis and the palaeomagnetic and the microfauna studies are shown, contrasting them with those from the analysis of the macrofauna, with which they show some important differences. This is accounted for the fact that the biostratigraphic sequence of Olduvai has been the only comparative framework so far. After stressing the need for broadening such framework, bearing the palaeoecological context in mind, the stratigraphic biozonation of Peninj is re-examined by comparing it to the biostratigraphy of Koobi Fora. The results thus obtained are similar to those drawn from the other types of analyses

Traitements des données de trafic : besoins, état de l'art, exemple de mise en oeuvre

Cette étude s'est intéressée particulièrement à la mise en oeuvre d'un outil de traitement de données de trafic pour les besoins du système global de gestion des déplacements de l'agglomération toulousaine. Cependant, la problématique du traitement des données et les solutions proposées sont largement transposables à d'autres contextes locaux. Ce rapport présente les différents acteurs gestionnaires de déplacements et leurs relations. Leurs besoins sont analysés, qui couvrent à la fois les services aux usagers et les besoins propres aux exploitants. Une revue des systèmes de traitements de données utilisés aujourd'hui permet de présenter différentes techniques de recueil et de fusion de données. Les spécifications techniques d'un système de traitement de données sont ensuite largement détaillées avec les méthodes utilisées dans les trois modules clés que sont le qualification des données, le filtrage et l'estimation par fusion de données, la prédiction des états du réseau. La mise en oeuvre du système proposé est ensuite présentée, avec le contenu de la base de données, les fichiers utilisés et l'implantation matérielle. Le document est complété par des références bibliographiques et des approfondissements techniques sur les méthodes de traitement de données de trafic proposées. Ce rapport s'adresse particulièrement aux gestionnaires de réseaux de circulation, qui reconnaîtront dans cette étude la problématique du traitement des données à laquelle ils sont quotidiennement confrontés. Ce document constitue pour eux des pistes de réflexion et un point de vue actuel sur les systèmes de traitement de données de trafic

Data from: Using satellite AIS to improve our understanding of shipping and fill gaps in ocean observation data to support marine spatial planning

1. A key stage underpinning marine spatial planning (MSP) involves mapping the spatial distribution of ecological processes and biological features, as well the social and economic interests of different user groups. One sector, merchant shipping (vessels that transport cargo or passengers), however, is often poorly represented in MSP due to a perceived lack of fine-scale spatially explicit data to support decision making processes. 2. Here, using the Republic of Congo as an example, we show how publicly accessible satellite derived Automatic Identification System (S-AIS) data can address gaps in ocean observation data for shipping at a national scale. We also demonstrate how fine-scale (0.05 km2 resolution) spatial data layers derived from S-AIS (intensity, occupancy) can be used to generate maps of vessel pressure to provide an indication of patterns of impact on the marine environment and potential for conflict with other ocean-user groups. 3. We reveal that passenger vessels, offshore service vessels, bulk carrier and cargo vessels and tankers account for 93.7% of all vessels and vessel traffic annually, and that these sectors operate in a combined area equivalent to 92% of Congo’s exclusive economic zone(EEZ) – far exceeding the areas allocated for other user-groups (conservation, fisheries and petrochemicals). We also show that the shallow coastal waters and habitats of the continental shelf are subject to more persistent pressure associated with shipping; and that the potential for conflict among user groups is likely to be greater with fisheries, whose zones are subject to the highest vessel pressure scores than with conservation or petrochemical sectors. 4. Synthesis and applications. Shipping dominates ocean use, and so excluding this sector from decision making could lead to increased conflict among user groups, poor compliance and negative environmental impacts. This study demonstrates how Satellite derived Automatic Identification System data can provide a comprehensive mechanism to fill gaps in ocean observation data and visualise patterns of vessel behaviour and potential threats to better support marine spatial planning at national scales.13-Feb-201
