Testing the influence of light on nitrite cycling rates in eastern tropical North Pacific

Autor: Nicole M. Travis, Colette L. Kelly, Karen L. Casciotti

Light is considered a strong controlling factor on nitrification rates in the surface ocean. Previous work has shown that ammonia oxidation and nitrite oxidation may be inhibited by high light levels, yet active nitrification has been measured in the

Coincident Biogenic Nitrite and pH Maxima Arise in the Upper Anoxic Layer in the Eastern Tropical North Pacific

The Eastern Tropical North Pacific (ETNP), like the other marine oxygen deficient zones (ODZs), is characterized by an anoxic water column, nitrite accumulation at the anoxic core, and fixed nitrogen loss via nitrite reduction to N₂O and N₂ gases

Nitrite Cycling in the Primary Nitrite Maxima of the Eastern Tropical North Pacific

Autor: Nicole M. Travis, Colette L. Kelly, Margaret R. Mulholland, Karen L. Casciotti

The primary nitrite maximum (PNM) is a ubiquitous feature of the upper ocean, where nitrite accumulates in a sharp peak at the base of the euphotic zone. This feature is situated where many chemical and hydrographic properties have strong gradients a

Phytoplankton are critical component of the food web in most large rivers and estuaries, and thus identifying dominant controls on phytoplankton abundance and species composition is important to scientists, managers, and policymakers. Recent studies

Publikováno v: Kimbro, David L.; Grosholz, Edwin D.; Baukus, Adam J.; Nesbitt, Nicholas J.; Travis, Nicole M.; Attoe, Sarikka; et al.(2009). Invasive species cause large-scale loss of native California oyster habitat by disrupting trophic cascades. Oecologia, 160(3), pp 563-575. doi: 10.1007/s00442-009-1322-0. Retrieved from: http://www.escholarship.org/uc/item/10q862q1

Although invasive species often resemble their native counterparts, differences in their foraging and anti-predator strategies may disrupt native food webs. In a California estuary, we showed that regions dominated by native crabs and native whelks h
