The essential role of large research vessels in marine ecosystem observations and ocean sustainability

open access: yesLimnology and Oceanography, EarlyView.
Abstract Our understanding of marine ecosystems and ability to manage them sustainably has come from multidisciplinary observations made repeatedly over long periods of time. These long‐term ecosystem observations depend on the capabilities of large research vessels, which play an essential role in the collection of global ocean observations.

Prolonged low flows and non‐native fish operate additively to alter insect emergence in mountain streams

open access: yesLimnology and Oceanography, EarlyView.
Abstract Climate‐induced flow alteration is decreasing snowpack and advancing snowmelt, subjecting mountain streams to longer low‐flow periods. Yet, anticipating how stream ecosystems respond to prolonged low flows remains challenging because distinct trophic levels can respond differently, and non‐native predators can dampen or amplify responses. Here,

Quantifying Eulerian Eddy Leakiness in an Idealized Model [PDF]

open access: yes, 2019
An idealized eddy‐resolving ocean basin, closely resembling the North Pacific Ocean, is simulated using MITgcm. We identify rotationally coherent Lagrangian vortices (RCLVs) and sea surface height (SSH) eddies based on the Lagrangian and Eulerian ...

Prairie stream nutrient stoichiometry across space and time: Influence of discharge, season, and crop type

open access: yesLimnology and Oceanography, EarlyView.
Abstract Stream water nutrient ratios are often influenced by flow variation and landscape characteristics. However, the influence of these drivers on total and dissolved nutrient ratios remains understudied, especially in prairie ecosystems where hydrologic connectivity between soils and streams exhibits substantial spatial and seasonal variability ...

Phylogeography of New Zealand’s coastal benthos [PDF]

open access: yes, 2009
During the past 30 years, 42 molecular studies have been undertaken in New Zealand to examine the phylogeography of coastal benthic invertebrates and plants. Here, we identify generalities and/or patterns that have emerged from this research and consider
