Globally, alterations of marine food webs due to overfishing of species at high trophic levels are leading to unpredictable changes in coastal ecosystems. In parts of the Western Indian Ocean, increasing abundances of sea urchins (particularly Tripneustes gratilla) have been observed. Sea urchins’ grazing intensity on seagrass beds is generally...
Research on the linkages between climate change, coastal communities and gender is scarce. In this presentation we address this from a marine resource management perspective based on ecosystem goods and services, gendered adaptive capacity and its links to transformative agency. The hypothesis is that there are gender differences in resource...
In Zanzibar, an increasing number of women have entered fish markets acting as a link between fishers and
consumers, i.e. a middleman. However, since fisheries are traditionally male dominated, women receive little
recognition. Thus, gender analysis in the fisheries sector potentially can enhance management and development
policies as well as...
En mayo de este año, la Revista Panamericana de Salud Pública dedicó un número especial a promover el proceso más reciente de reforma de salud en Ecuador como un caso exitoso en la región. En el artículo editorial, la directora de la Organización Panamericana de la Salud (OPS), Carissa Etienne,...
La discusión los lleva a decir cosas que los ofende y se empujan.
El carrito de Yolanda se voltea y los paquetes de comida se riegan
en todo el suelo de la cochera. Mientras observan el desorden se
acusan el uno al otro, “Tú lo hiciste y le voy a...
Mean fields, seasonal cycles, and interannual variability are examined for fields of
satellite-derived chlorophyll pigment concentrations (CHL), sea surface height (SSH), and
sea surface temperature (SST) during 1997–2002. The analyses help to identify three
dynamic regions: an upwelling zone next to the coast, the Ensenada Front in the north,
and...
Olive ridley sea turtles (Lepidochelys olivacea) present an interesting case study of the conservation of wildlife species that aggregate in high densities and have served as resources for human consumption. Ridleys exhibit synchronized mass-nesting behavior,
during events called "arribadas," where thousands of females lay eggs together in a small area...
The 2-ka eruption of Misti volcano produced voluminous flowage deposits and a wide-spread tephra-fall deposit. The flowage deposits form large terraces within channels draining the south side of the volcano. All the channels drain into the city of Arequipa. Arequipa's city center is ~16 km from the summit of the...
