Consumer diversity drives stronger predation in tropical marine communities
Ecography, EarlyView.Biotic interactions are predicted to be stronger in the tropics compared to higher latitudes, contributing to observed patterns of global biodiversity. While increased consumer diversity and more complex food webs are expected in tropical communities, the trophic dynamics underlying strong regional effects of predation are not well understood.

Ecography, EarlyView.Ocean warming is driving the redistribution of species at a global scale. Biogeographic transition zones are hotspots of species range shifts, as both warm‐ and cold‐adapted species are found toward contrasting range edges. While anecdotal evidence suggests some distributional shifts have occurred in the northeast Atlantic, the empirical evidence base ...

Abstract The deep ocean environment is the most extensive on our planet. Its denizens are normally unseen but whenever they are exposed to view they are regarded as bizarre aliens from a different world. The Biology of the Deep Ocean takes a close look at this apparently hostile world and explains how its inhabitants are exquisitely ...

Deep ocean influence at ocean boundaries
2016The continental slope has an important influence on ocean dynamical variability, the steep slopes leading to rapid signal propagation and a smoothing of pressure variability along the slope. As a result, pressure variations tend to be smaller than nearby sea level variability would suggest, and mesoscale variability is suppressed.

Up to now we have discussed ocean currents only in the surface layer, i.e. above the main or permanent thermocline. This layer constitutes approximately 10% of the volume of the World Ocean. It was amply demonstrated that the major current systems in the upper strata are generated by atmospheric forces.

Paleoceanography Have changes in ocean circulation contributed to the sudden increases in the concentration of atmospheric carbon dioxide that occurred during the last deglaciation? Chen et al. provide a high-resolution radiocarbon record for that time, derived from deep sea corals.

How deep is the ocean? To find the answer to this question is not as simple as you may think. Ocean mapping technology has developed over time, and there have been many advances like the invention of sonar. But it is a fact that Mars is better mapped than of our own ocean floor.

Introduction The deep sea is defined as water depth greater than 200 m, thereby excluding the continental shelf (Chapter 15). Deep-sea environments are present over 65% of the Earth's surface, and include ocean basins, oceanic trenches, island-arc basins, marginal seas, and downfaulted continental borderlands (Figure 18.1).
