Galápagos and Californian sea lions are separate species: Genetic analysis of the genus Zalophus and its implications for conservation management [PDF]

Frontiers in Zoology, 2007
Background Accurate formal taxonomic designations are thought to be of critical importance for the conservation of endangered taxa. The Galápagos sea lion (GSL), being appreciated as a key element of the Galápagos marine ecosystem, has lately been listed

A critical analysis of the discourses of conservation and science on the Galápagos Islands [PDF]

, 2011
Conservation of the world’s biodiversity is a paradigmatic example of a ‘wicked problem’, a problem that resists resolution because it is defined, experienced and measured differently by different people, in ways that are inseparable from a range of ...

'Rooting,' For Change: The Role of Culture Beyond Resilience and Adaptation

Conservation & Society, 2022
Confronted with concerns about rising biodiversity loss and pollution, conservation on the Galápagos has recently moved away from the goal of preserving pristine ecosystems to managing a complex socio-ecological system (SES).

Volcanic event management in the Galápagos Islands, Ecuador

Volcanica, 2022
The volcanoes of Galápagos, Ecuador, are among the most active in the world, with an average of five eruptions per decade. Monitoring and communication of their activity are essential for timely management of events. In this context, the Instituto Geofí

Pelagic sea cucumbers in the Galapagos: Midwater grazers that short-circuit deep-sea carbon flux. [PDF]

Ecology
Abstract Direct observations from submersible dives off the Galapagos Islands have revealed that Pelagothuria natatrix, the only known holopelagic echinoderm, actively intercepts settling particles well before they can reach the deep seafloor, thereby short‐circuiting the typical downward flux of organic carbon generated in the photic zone.

Soil Fertility Changes With Climate and Island Age in Galápagos: New Baseline Data for Sustainable Agricultural Management

Frontiers in Environmental Science, 2021
While the extended absence of human influence has led to matchless natural conditions on the Galápagos archipelago, agricultural activities on the inhabited islands are increasingly affecting soil health and functioning.

Environment-driven changes in terrestrial habitat use and distribution of the Galapagos sea lion

Endangered Species Research, 2014
Understanding habitat use patterns of marine apex predators is of paramount importance for the effective design of conservation plans. Due to their amphibious life cycle, pinnipeds are one of the most vulnerable groups to habitat loss and degradation ...

The Effects of Climatic Variability on the Feeding Ecology of the Scalloped Hammerhead Shark (Sphyrna lewini) in the Tropical Eastern Pacific

Frontiers in Marine Science, 2021
Climatic variability changes ocean productivity and generates systematic cascading effects in marine food webs. Studying the feeding ecology of top predators, such as sharks, can provide insights into the overall health of marine ecosystems. We conducted

Tracing early stages of species differentiation: Ecological, morphological and genetic divergence of Galapagos sea lion populations [PDF]

, 2008
Background: Oceans are high gene flow environments that are traditionally believed to hamper the build-up of genetic divergence. Despite this, divergence appears to occur occasionally at surprisingly small scales.
