The study of habitat fragmentation found its roots early, with Aldo Leopold’s ideas on edge effect and Robert MacArthur and E. O. Wilson’s studies and models of island biogeography laying a foundation for the field (Laurance and Bierregaard 1997). These concepts offer potential applicable and hypothetico-deductive value for the study of ...
The Tyrreno-ROMS model was used to measure the ocean current or gyres along with the sea surface temperatures in the fin whales' habitat within the Mediterranean Sea. [ 219 ] The results of the studies indicated that there were high levels of microplastics within the surface level of the Mediterranean Sea which is the fin whales' habitat and ...
The other model is the variegation model. Variegated landscapes retain much of their natural vegetation but are intermixed with gradients of modified habitat [84] This model of habitat fragmentation typically applies to landscapes that are modified by agriculture. In contrast to the fragmentation model that is denoted by isolated patches of ...
The SLOSS debate was a debate in ecology and conservation biology during the 1970's and 1980's as to whether a single large or several small (SLOSS) reserves were a superior means of conserving biodiversity in a fragmented habitat. Since its inception, multiple alternate theories have been proposed.
Logging, fire, farming, and reforestation can all contribute to the process of colonization, and can effectively change the shape of the patch. Patch dynamics also refers to changes in the structure, function, and composition of individual patches that can, for example, affect the rate of nutrient cycling [citation needed]. Patches are also linked.
Plastic pollution in the ocean is a type of marine pollution by plastics, ranging in size from large original material such as bottles and bags, down to microplastics formed from the fragmentation of plastic material. Marine debris is mainly discarded human rubbish which floats on, or is suspended in the ocean.
The ocean's surface is hit hard by anthropogenic change, and the surface ecosystem is likely already dramatically different from even a few hundred years ago. For example, prior to widespread damming, logging, and industrialisation, more wood may have entered the open ocean, [ 14 ] while plastic had not yet been invented.
The pelagic food web, showing the central involvement of marine microorganisms in how the ocean imports carbon and then exports it back to the atmosphere and ocean floor The biological pump (or ocean carbon biological pump or marine biological carbon pump ) is the ocean's biologically driven sequestration of carbon from the atmosphere and land ...
