Marine traffic is increasing globally yet collisions with endangered megafauna such as whales, sea turtles, and planktivorous sharks go largely undetected or unreported. Collisions leading to ...mortality can have population-level consequences for endangered species. Hence, identifying simultaneous space use of megafauna and shipping throughout ranges may reveal as-yet-unknown spatial targets requiring conservation. However, global studies tracking megafauna and shipping occurrences are lacking. Here we combine satellite-tracked movements of the whale shark, Rhincodon typus, and vessel activity to show that 92% of sharks’ horizontal space use and nearly 50% of vertical space use overlap with persistent large vessel (>300 gross tons) traffic. Collision-risk estimates correlated with reported whale shark mortality from ship strikes, indicating higher mortality in areas with greatest overlap. Hotspots of potential collision risk were evident in all major oceans, predominantly from overlap with cargo and tanker vessels, and were concentrated in gulf regions, where dense traffic co-occurred with seasonal shark movements. Nearly a third of whale shark hotspots overlapped with the highest collision-risk areas, with the last known locations of tracked sharks coinciding with busier shipping routes more often than expected. Depth-recording tags provided evidence for sinking, likely dead, whale sharks, suggesting substantial “cryptic” lethal ship strikes are possible, which could explain why whale shark population declines continue despite international protection and low fishing-induced mortality. Mitigation measures to reduce ship-strike risk should be considered to conserve this species and other ocean giants that are likely experiencing similar impacts from growing global vessel traffic.
El proyecto Fortalecimiento de Capacidades en Personas con Discapacidad para su Inserción Laboral. Ayacucho - 2019. Es una investigación de tipo aplicativo y diseño cuasi experimental, tiene como ...objetivo “Proponer al mercado laboral personas con discapacidad acreditados como Asistente Administrativo de Recursos Humanos y Asistente de Logística.”. La Muestra fue Censal, los estudios se realizaron en el Laboratorio de la E.P. de Enfermería. Sus conclusiones fueron: 1. En el proyecto de Fortalecimiento de Capacidades Laborales: el 60% son hombres; el 56% mayores 41 años. 2. En el mismo curso solo el 59.4% de los inscritos iniciaron el curso - 10.5% lo hicieron en el curso taller de Asistente de Administración de Recursos Humanos y el 89.5% lo hicieron en el curso taller de Asistente de Logística. 3. El 10.5% concluyeron el curso Asistente de Administración de Recursos Humanos ambos hombres, el 63.1%, concluyeron el curso de Asistente de Logística: 6 hombres y seis mujeres 4. De los capacitados y acreditados 35.7% ya están insertados en el mercado laboral.
The sequences of RNA-3 and RNA-4 of rice hoja blanca tenuivirus isolates from Colombia and from Costa Rica were determined and analyzed. These isolates were 98.9% and 98.6% identical in the coding ...and non-coding regions of RNA-3, and 96.9 and 91.5% identical in the coding and non-coding regions of RNA-4, and are therefore strains of the same virus. There is about three times as much variation between isolates (based on consensus sequences) as there is within isolates (based on sequences of individual clones). There is also considerably more variation for RNA-4 (both between and within isolates) than there is for RNA-3, even though between tenivirus species RNA-3 has diverged more than RNA-4, implying that the evolution of the tenuivirus RNAs is not necessarily dependent on the amount of variation found for these RNAs.
