Data from: Acute febrile illness and influenza disease burden in a rural cohort dedicated to malaria in Senegal, 2012-2013Fatoumata Diene Sarr, Mbayame Niang, Diamilatou Thiam, Ndongo Dia, Abdoulaye Badiane, Abdoulaye B. Ndao, Cheikh Sokhna, André Spiegel & Vincent Richard
Background: African populations are considered to be particularly vulnerable to fever illnesses, including malaria, and acute respiratory disease, owing to limited resources and overcrowding. However, the overall burden of influenza in this context is poorly defined and incidence data for African countries are scarce. We therefore studied the fever syndrome incidence and more specifically influenza incidence in a cohort of inhabitants of Dielmo and Ndiop in Sokone district, Senegal. Methods: Daily febrile-illness data were prospectively...
Population ecology has classically focused on pairwise species interactions, hindering the description of general patterns and processes of population abundance at large spatial scales. Here we use the Metabolic Theory of Ecology as a framework to formulate and test a model that yields predictions linking population density to the physiological constraints of body size and temperature on individual metabolism, and the ecological constraints of trophic structure and species richness on energy partitioning among species. Our...
Data from: How to capture fish in a school? Effect of successive predator attacks on seabird feeding successAndréa Thiebault, Magali Semeria, Christophe Lett & Yann Tremblay
1. Prey aggregations, such as fish schools, attract numerous predators. This typically leads to the formation of multi-specific groups of predators. These aggregations can be seen both as a place of increased competition and as a place of possible facilitation between predators. Consequently, the functional role of such predator-prey aggregation is uncertain, and its effect on individual feeding success is virtually unknown. 2. Using underwater film footages of different predators feeding on fish schools during...
Data from: Benefits and challenges of scaling up expansion of marine protected area networks in the Verde Island Passage, Central PhilippinesVera Horigue, Robert L. Pressey, Morena Mills, Jana Brotanková, Reniel Cabral & Serge Andrefouet
Locally-established marine protected areas (MPAs) have been proven to achieve local-scale fisheries and conservation objectives. However, since many of these MPAs were not designed to form ecologically-connected networks, their contributions to broader-scale goals such as complementarity and connectivity can be limited. In contrast, integrated networks of MPAs designed with systematic conservation planning are assumed to be more effective—ecologically, socially, and economically—than collections of locally-established MPAs. There is, however, little empirical evidence that clearly demonstrates the...
Data from: Spatial structure of above-ground biomass limits accuracy of carbon mapping in rainforest but large scale forest inventories can help to overcomeStéphane Guitet, Bruno Hérault, Quentin Molto, Olivier Brunaux & Pierre Couteron
Precise mapping of above-ground biomass (AGB) is a major challenge for the success of REDD+ processes in tropical rainforest. The usual mapping methods are based on two hypotheses: a large and long-ranged spatial autocorrelation and a strong environment influence at the regional scale. However, there are no studies of the spatial structure of AGB at the landscapes scale to support these assumptions. We studied spatial variation in AGB at various scales using two large forest...
We investigated the extent that the 2010 Deepwater Horizon oil spill potentially affected oceanic-stage sea turtles from populations across the Atlantic. Within an ocean-circulation model, particles were backtracked from the Gulf of Mexico spill site to determine the probability of young turtles arriving in this area from major nesting beaches. The abundance of turtles in the vicinity of the oil spill was derived by forward-tracking particles from focal beaches and integrating population size, oceanic-stage duration...
Data from: Predictive modelling of habitat selection by marine predators with respect to the abundance and depth distribution of pelagic preyCharlotte Boyd, Ramiro Castillo, , André E. Punt, Glenn R. VanBlaricom, Henri Weimerskirch, Sophie Bertrand & George L. Hunt
1. Understanding the ecological processes that underpin species distribution patterns is a fundamental goal in spatial ecology. However, developing predictive models of habitat use is challenging for species that forage in marine environments, as both predators and prey are often highly mobile and difficult to monitor. Consequently, few studies have developed resource selection functions for marine predators based directly on the abundance and distribution of their prey. 2. We analysed contemporaneous data on the diving...
