2015/12/11
Marine protected areas (MPAs) that excludefishing have been shown repeatedly to enhance the abundance, size, and diversity of species.
These benefits, however, mean little to most marine ...
Biodiversity is Biogeography:Implications for Conservation
Biodiversity Biogeography Conservation
2015/8/13
Three themes dominate this review. The first is that biodiversity is biogeography. Or, as Nelson and Ladiges (1990) put it: "Indeed, what beyond biogeography is 'biodiversity' about?" Second, watershe...
The Role of Marine and Coastal Protected Areas in the Conservation and Sustainable Use of Biological Diversity
Marine and Coastal Protected Areas Conservation and Sustainable Biological Diversity
2015/8/13
At a time when threats to the marine environment have never seemed greater, the importance of marine biological diversity and its conservation have never been more clear. While the traditional measure...
Population Connectivity and Conservation of Marine Biodiversity
Population Connectivity Conservation Marine Biodiversity
2015/7/22
An understanding of the extent to which marine populations are connected by larval dispersal is vital, both to comprehend past impacts and future prospects for sustaining biodiversity. Marine populati...
I have used these authors' previous text, Coastal-Marine Conservation: Science and Policy (2004), in an upper-level undergraduate course on coastal marine conservation for several years, and have been...
A decade of Ridge 2000 and related research has yielded new and refined understanding of events and processes that occur on mid-ocean ridge and back-arc spreading centers, as reported in this special ...
Can We Protect Seamounts for Research?A Call For Conservation
Protect Seamounts Call For Conservation
2015/7/7
Extractive processes such as fishing and mining are degrading seamount ecosystems considerably, raising serious concerns about the impacts of these practices on global ocean biodiversity and key fluxe...
BOOK REVIEW | The Silent Deep:The Discovery,Ecology,and Conservation of the Deep Sea
Silent Deep Discovery Ecology Conservation of the Deep Sea
2015/7/7
The deep sea represents one of the last great frontiers on Earth. Although once thought devoid of life, technology has brought the true abundance of deep ocean life into our human consciousness. Koslo...
Advances in Conservation Oceanography: New Tagging and Tracking Technologies and Their Potential for Transforming the Science Underlying Fisheries Management
Conservation Oceanography New Tagging
2015/7/3
Overexploitation of living resources and climate change are among the most obvious global-scale impacts of human society on marine ecosystems. In an age of such large-scale anthropogenic impacts, mari...
Maps from the Mid-Ocean Dynamics Experiment：Part II. Potential vorticity and its Conservation
Mid-Ocean Dynamics Experiment Conservation Potential vorticity
2009/3/7
Observations of float trajectories and vertical density profiles from the Mid-Ocean Dynamics Experiment are analyzed in terms of a likely equation of motion for mesoscale eddies involving the conserva...
Conservation Calculations in Natural Coordinates (with an Example from the Baltic)
Conservation Calculations Natural Coordinates
2009/2/13
Conservation expressions for a fluid property i* (e.g., salt, heat) and mass are derived for a semi-enclosed, stratified region as functions of a concentration j (e.g., salinity, temperature) and time...
Quasi-linear Eddy-Viscosity Model for the Flux of Energy and Momentum to Wind Waves Using Conservation-Law Equations in a Curvilinear Coordinate System
Curvilinear Coordinate System Quasi-linear Eddy-Viscosity Model
2008/12/22
The airflow above ocean waves is calculated using a quasi-linear model—one in which the effect of the waves on the mean flow is taken into account. The model uses curvilinear coordinates, in which one...
The Temporal-Residual-Mean Velocity. Part I：Derivation and the Scalar Conservation Equations
temporal-residual-mean Scalar Conservation Equations eddy fluxes
2008/12/11
The time-averaged density conservation equation in z coordinates contains a forcing term that is the divergence of the transient eddy fluxes. These fluxes are due to the temporal correlation between t...
On Conservation Equations in Oceanography: How Accurate Are Boussinesq Ocean Models
Conservation Equations Oceanography Boussinesq Ocean Models
2008/6/6
Traditionally, the conservation equations in oceanography include the Boussinesq approximation, and the velocity variable is interpreted as the Eulerian mean velocity averaged over turbulent scales. I...
Genetic diversity in the Gammarus pecos species complex: Implications for conservation and regional biogeography in the Chihuahuan Desert
Genetic diversity Gammarus pecos species complex conservation and regional biogeography Chihuahuan Desert
2014/5/14
We used allozyme electrophoresis to quantify genetic variation in nine populations of the Gammarus pecos species complex endemic to spring systems of the northern Chihuahuan Desert. There was signific...
