Effects of simulated overfishing on the succession of benthic algae and invertebrates in an upwelling-influenced coral reef of Pacific Costa Rica

Roth, F.; Stuhldreier, I.; Sánchez-Noguera, C.; Morales-Ramírez, Á.; Wild, C. (Elsevier B.V., 2015)

Overfishing and nutrient enrichment are among the major local stressors to coral reefs worldwide, as they can alter the benthic reef community by promoting fast growing algae and bioeroders. The Northern coast of Pacific ...

From wing to wing: the persistence of long ecological interaction chains in less-disturbed ecosystems

McCauley, Douglas J.; DeSalles, Paul A.; Young, Hillary S.; Dunbar, Robert B.; Dirzo, Rodolfo; Mills, Matthew M.; Micheli, Fiorenza (Scientific Reports, 2012-05-17)

Human impact on biodiversity usually is measured by reduction in species abundance or richness. Just as important, but much more difficult to discern, is the anthropogenic elimination of ecological interactions. Here we ...

Historical Overﬁshing and the Recent Collapse of Coastal Ecosystems

Jackson, Jeremy B.C.; Kirby, Michael X.; Berger, Wolfgang H.; Bjorndal, Karen A.; Botsford, Louis W.; Bourque, Bruce J.; Bradbury, Roger H.; Cooke, Richard; Erlandson, Jon; Estes, James A.; Hughes, Terence P.; Kidwell, Susan; Lange, Carina B.; Lenihan, Hunter S.; Pandolﬁ, John M.; Peterson, Charles H.; Steneck, Robert S.; Tegner, Mia J.; Warner, Robert R. (American Association for the Advancement of Science, 2001-07-27)

Ecological extinction caused by overﬁshing precedes all other pervasive human disturbance to coastal ecosystems, including pollution, degradation of water quality, and anthropogenic climate change. Historical abundances ...

Evidence for middle Cretaceous accretion at Santa Elena Peninsula (Santa Rosa Accretionary Complex), Costa Rica

Baumgartner, P. O.; Denyer, P. (Geologica Acta, 2006)

An oceanic assemblage of alkaline basalts, radiolarites and polymictic breccias forms the tectonic substratum of the Santa Elena Nappe, which is constituted by extensive outcrops of ultramafic and mafic rocks of the Santa ...

Micro-environment of olive ridley turtle nests deposited during an aggregated nesting event

Clusella Trullas, Susana; Paladino, F.V. (The Zoological Society of London, 2007)

The hatching success of nests deposited by olive ridley turtles Lepidochelys olivacea during aggregated nesting events (‘arribada’) is typically low and the underlying mechanisms are not clear. In this study, temperature, ...

A new species of poeciliid fish, Poeciliopsis santaelena, from Peninsula Santa Elena, Area de Conservación Guanacaste, Costa Rica
