Continental-scale acoustic telemetry networks are increasingly being established worldwide, producing large volumes of information-rich geospatial data. During the last decade, the Integrated Marine Observing System’s Animal Tracking Facility (IMOS ATF) established a permanent array of acoustic receivers around Australia. Simultaneously, IMOS developed a centralised national database to foster collaborative research across the user community and quantify individual behaviour across a broad range of taxa. Here we present the database and quality control procedures developed to collate 49.6 million valid detections from 1891 receiving stations. This dataset consists of detections for 3,777 tags deployed on 117 marine species, with distances travelled ranging from a few to thousands of kilometres. Connectivity between regions was only made possible by the joint contribution of IMOS infrastructure and researcher-funded receivers. This dataset constitutes a valuable resource facilitating meta-analysis of animal movement, distributions, and habitat use, and is important for relating species distribution shifts with environmental covariates

A composite transcriptional signature differentiates responses towards closely related herbicides in Arabidopsis thaliana and Brassica napus

In this study, genome-wide expression profiling based on Affymetrix ATH1 arrays was used to identify discriminating responses of Arabidopsis thaliana to five herbicides, which contain active ingredients targeting two different branches of amino acid biosynthesis. One herbicide contained glyphosate, which targets 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS), while the other four herbicides contain different acetolactate synthase (ALS) inhibiting compounds. In contrast to the herbicide containing glyphosate, which affected only a few transcripts, many effects of the ALS inhibiting herbicides were revealed based on transcriptional changes related to ribosome biogenesis and translation, secondary metabolism, cell wall modification and growth. The expression pattern of a set of 101 genes provided a specific, composite signature that was distinct from other major stress responses and differentiated among herbicides targeting the same enzyme (ALS) or containing the same chemical class of active ingredient (sulfonylurea). A set of homologous genes could be identified in Brassica napus that exhibited a similar expression pattern and correctly distinguished exposure to the five herbicides. Our results show the ability of a limited number of genes to classify and differentiate responses to closely related herbicides in A. thaliana and B. napus and the transferability of a complex transcriptional signature across species

Observations and models to support the first Marine Ecosystem Assessment for the Southern Ocean (MEASO)

Assessments of the status and trends of habitats, species and ecosystems are needed for effective ecosystem-based management in marine ecosystems. Knowledge on imminent ecosystem changes (climate change impacts) set in train by existing climate forcings are needed for adapting management practices to achieve conservation and sustainabililty targets into the future. Here, we describe a process for enabling a marine ecosystem assessment (MEA) by the broader scientific community to support managers in this way, using a MEA for the Southern Ocean (MEASO) as an example. We develop a framework and undertake an audit to support a MEASO, involving three parts. First, we review available syntheses and assessments of the Southern Ocean ecosystem and its parts, paying special attention to building on the SCAR Antarctic Climate Change and Environment report and the SCAR Biogeographic Atlas of the Southern Ocean. Second, we audit available field observations of habitats and densities and/or abundances of taxa, using the literature as well as a survey of scientists as to their current and recent activities. Third, we audit available system models that can form a nested ensemble for making, with available data, circumpolar assessments of habitats, species and food webs. We conclude that there is sufficient data and models to undertake, at least, a circumpolar assessment of the krill-based system. The auditing framework provides the basis for the first MEASO but also provides a repository (www.SOKI.aq/display/MEASO) for easily amending the audit for future MEASOs. We note that an important outcome of the first MEASO will not only be the assessment but also to advise on priorities in observations and models for improving subsequent MEASOs

Greater weight loss with the omega loop bypass compared to the Roux-en-Y gastric bypass: a comparative study

International audienceBACKGROUND: Despite similar initial results on weight loss and metabolic control, with a better feasibility than the Roux-en-Y gastric bypass (RYGBP), the omega loop bypass (OLB) remains controversial. The aim of this study was to compare the short-term outcomes of the laparoscopic OLB versus the RYGBP in terms of weight loss, metabolic control, and safety. METHODS: Two groups of consecutive patients who underwent laparoscopic gastric bypass surgery were selected: 20 OLB patients and 61 RYGBP patients. Patients were matched for age, gender, and initial body mass index (BMI). Data concerning weight loss, metabolic outcomes, and complications were collected prospectively. RESULTS: Mean duration of the surgical procedure was shorter in the OLB group (105 vs. 152 min in the RYGBP group; p \textless 0.001). Mean excess BMI loss percent (EBL%) at 6 months and at 1 year was greater in the OLB group (76.3 vs. 60.0%, p = 0.001, and 89.0 vs. 71.0%, p = 0.002, respectively). After adjustment for age, sex, initial BMI, and history of previous bariatric surgery, the OLB procedure was still associated with a significantly greater 1-year EBL%. Diabetes improvement at 6 months was similar between both groups. The early and late complication rates were not statistically different. There were three anastomotic ulcers in the OLB group, in smokers, over 60 years old, who were not taking proton pump inhibitor medication. CONCLUSIONS: In this short-term study, we observed a greater weight loss with OLB and similar efficiency on metabolic control compared to RYGBP. Long-term evaluation is necessary to confirm these outcomes

Gastric bypass for obesity in the elderly: is it as appropriate as for young and middle-aged populations?

International audienceBACKGROUND: Obesity prevalence increases in elderly population. Bariatric surgery has been underused in patients over 60 because of fears of complications and lower weight loss. We postulated worse outcomes in the elderly in comparison to young and middle-aged population 1 year after gastric bypass. METHODS: We retrospectively analyzed gastric bypass outcomes in young (\textless40 years), middle-aged (40 to 55 years), and elderly (\textgreater60 years) patients between 2007 and 2013. Each subject over 60 (n = 24) was matched with one subject of both the other groups according to gender, preoperative body mass index (BMI), surgical procedure, and history of previous bariatric surgery (n = 72). RESULTS: Older subjects demonstrated higher prevalence of preoperative metabolic comorbidities (70 vs 30 % in the \textless40-year-old group, p \textless 0.0001). Mean duration of the surgical procedure, mean length of stay, and early and late complication rates were similar between age groups. A trend towards fewer early complications and less-severe complications in the younger groups was noted. One-year weight loss results were similar between young, middle-aged, and elderly patients (percentage of excess BMI loss (EBL%), 74.4 +/- 3.5; 78.9 +/- 4.5, and 73.7 +/- 4.5 respectively, p = 0.69). Age was not predictive of weight loss failure 1 year after surgery. Remission and improvement rates of comorbidities were similar between age groups 6 months after surgery. CONCLUSIONS: Our study confirms weight loss efficacy of gastric bypass in the elderly with acceptable risks. Further studies evaluating the benefit-risk balance of bariatric surgery in the elderly population will be required so as to confirm the relevance of increasing age limit
