Unlike the Northern Hemisphere (Northern Atlantic and Pacific Ocean) where land masses provide a barrier which hinders the connection to other ocean basins, the Southern Hemisphere is open to the propagation of southern swell towards all ocean basins due to the fact that a circumpolar oceanic zone free of land barriers connects them together [25].
It is postulated that mangroves have dispersed widely, influenced by continental drift and other vicariant events, on top of species-specific long distance dispersal limited by land barriers and direction of ocean currents.
They believe that separated by the land barrier, species evolved to adapt to their new surroundings, becoming separate "sister species".
The researchers report the findings in the current issue of the journal Proceedings of the Royal Society B. The Central American isthmus — the strip of land that separates North and South America — rose about three million years ago, creating a land barrier between the Atlantic and Pacific Oceans.
The Pyrenees mountain range forms an effective land barrier in the northeast, separating the Iberian Peninsula from the rest of Europe, and in the south at Gibraltar the peninsula is separated from North Africa by the narrow Strait of Gibraltar.
This land barrier protected Bruges from bombardment by land or sea by all but the very largest calibre artillery and also secured it against raiding parties from the Royal Navy.
Accordingly, the present-day Gulf attained its current form as a result of the separation of the Cape region from mainland and the break of the land barrier separating the two basins.
The dichotomous genetic differentiation into Indian and Pacific Ocean lineages have been reported in other mangrove species [ 36, 37] and coastal fauna [ 38, 39], and was attributed to the role of Sundaland as a land barrier during past glaciations periods.

Sometimes the slurry is pumped straight from the boats in heavy plumes, landing between barriers marking off what will become solid ground.
Findings from a multinomial logit model of estate planning actions suggest that landowner and land characteristics, barriers to the planning process, and intentions to pass to heirs, recreational and financial investment objectives, and landscape area differences explain variation in the extent and type of planning by owners.
