Permanent El Niño-like conditions during the Pliocene warm period.
During the warm early Pliocene (approximately 4.5 to 3.0 million years ago), the most recent interval with a climate warmer than today, the eastern Pacific thermocline was deep and the average west-to-east sea surface temperature difference across the equatorial Pacific was only 1.5 +/- 0.9 degrees C, much like it is during a modern El Niño event. Thus, the modern strong sea surface temperature...
متن کاملThe impact of El Niño events on the pelagic food chain in the northern California Current.
The zooplankton of the northern California Current are typically characterized by an abundance of lipid-rich copepods that support rapid growth and survival of ecologically, commercially, and recreationally valued fish, birds, and mammals. Disruption of this food chain and reduced ecosystem productivity are often associated with climatic variability such as El Niño events. We examined the varia...
متن کاملLong-term aggregation of larval fish siblings during dispersal along an open coast.
Pelagic dispersal of most benthic marine organisms is a fundamental driver of population distribution and persistence and is thought to lead to highly mixed populations. However, the mechanisms driving dispersal pathways of larvae along open coastlines are largely unknown. To examine the degree to which early stages can remain spatially coherent during dispersal, we measured genetic relatedness...
متن کاملCatastrophe, recovery and range limitation in NE Pacific kelp forests: a large-scale perspective
The 1997–98 El Niño was one of the strongest on record and resulted in widespread losses of the giant kelp Macrocystis pyrifera (Agardh) along the west coast of North America. Drawing on a rich history of studies that have shown abnormally large waves and warm nutrient-poor water associated with El Niños to negatively impact giant kelp populations at some locations in southern and Baja Californ...
متن کاملSpatial and temporal variations of the estuarine larval fish community on the west coast of Taiwan
Spatio–temporal variations in the distribution and community structure of the estuarine larval fishes on the west coast of Taiwan was examined in the estuaries of Shuangchi Creek (SC), Gongshytyan Creek (GST), Tatu Creek (TT) and Tongkang River (TK). Fish were collected by a net (mesh 0.8–1.8 mm) set against the flood tide at night during the newand full-moon periods from September 1997 through...
