The influence of rivers on seabird foraging ecology

open access: yesBiological Reviews, EarlyView.
ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...

Nuevos casos de Paracoccidioidomicosis

open access: yesRevista Peruana de Medicina Experimental y Salud Pública, 1998
La paracoccidioidomicosis es causada por el hongo Paracoccidioides brasiliensis. Esta infección es crónica y usualmente asintomática en niños. La distribución geográfica está limitada a Centroamérica y América del Sur. En el presente estudio se describen

Phytoplankton oceanographic characterization during El Niño 2004 event in the Northwest region of Baja California, Mexico

open access: yesRevista Bio Ciencias, 2016
An oceanographic cruise in front of the Coast of Baja California was carried from the 9th to the 29th day of July in 2004, in 91 stations at 10 m depth.

El niño vampiro y el cazador [PDF]

open access: yes, 2014
Si bien el vampiro es, tal vez, el más célebre en la galería de monstruos que cobrarán fama sobre todo a partir de la conocida serie de películas de la casa Universal Pictures, es indudable que su conocida efigie le ha llevado a un punto de ...

Extent, characteristics and policy applications of Key Biodiversity Areas

open access: yesBiological Reviews, EarlyView.
ABSTRACT A global standard for the identification of Key Biodiversity Areas (KBAs) was published 10 years ago to provide a unified set of criteria for identifying ‘sites of significance for the global persistence of biodiversity’. We review the initiative's origins, the KBA identification process, characteristics of the current network, threats, policy

Southern oscillation signal in South American palaeoclimatic data of the last 7000 years [PDF]

open access: yes, 1993
During strong El Niño events, rainfall anomalies and changes in wind patterns are observed in different regions of South America. Along the central Brazilian coast, during the 1983 El Niño year, the frontal systems were blocked to the south, provoking a ...

Environmental and local habitat variables as predictors of trophic interactions in subtidal rocky reefs along the SE Pacific coast

open access: yesEcography, EarlyView.
Temperature generally drives latitudinal patterns in the strength of trophic interactions, including consumption rates. However, local community and other environmental conditions might also affect consumption, disrupting latitudinal gradients, which results in complex large‐scale patterns.

A model study of oceanic mechanisms affecting Equatorial Pacific sea surface temperature during the 1997-98 El Niño [PDF]

open access: yes, 2001
In this study, the processes affecting sea surface temperature variability over the 1992–98 period, encompassing the very strong 1997–98 El Niño event, are analyzed.

Consumer diversity drives stronger predation in tropical marine communities

open access: yesEcography, EarlyView.
Biotic interactions are predicted to be stronger in the tropics compared to higher latitudes, contributing to observed patterns of global biodiversity. While increased consumer diversity and more complex food webs are expected in tropical communities, the trophic dynamics underlying strong regional effects of predation are not well understood.

Temporal shifts in kelp forest structure and distribution largely reflect recent ocean warming trends

open access: yesEcography, EarlyView.
Ocean warming is driving the redistribution of species at a global scale. Biogeographic transition zones are hotspots of species range shifts, as both warm‐ and cold‐adapted species are found toward contrasting range edges. While anecdotal evidence suggests some distributional shifts have occurred in the northeast Atlantic, the empirical evidence base ...
