The metabolic theory of ecology and the role of body size in marine and freshwater ecosystems
2007Introduction Body size is the single most important axis of biodiversity. Organisms range in body size over about 22 orders of magnitude, from tiny bacteria such as Mycoplasma weighing 10 13 g to giant Sequoia trees weighing 10 g. Such size variation is a pervasive feature of aquatic ecosystems, where the size spectrum spans at least 20 orders of ...

In this study, we measured the mercury concentration in 27 different fish species with high commercial value. Samples were taken from a region characterized by the diversity of aquatic environments. Mercury concentration in marine fish species varied from 30.4 to 216 ng g(-1), while in estuarine species, it varied from 12.4 to 60.3 ng g(-1).

Terrestrial mushrooms dominate mycology; their aquatic relatives are a fascinating and ecologically significant group. Psathyrella aquatica , the sole single‐gilled genus with underwater‐reported fruiting bodies, and marine‐dwelling genera such as Nia ...

AbstractAdaptive radiations are typically triggered when a lineage encounters a significant range of open niche space (ecological opportunity), stemming from colonisation of new areas, extinction of competitors or key innovations. The most well‐known of these is the colonisation of new areas, through either dispersal into new regions or the invasion of

Most of Latin America, with the exception of northern Mexico, Chile, Argentina, Uruguay, and the southern tip of Brazil, is located between the Tropic of Cancer and the Tropic of Capricorn. The tropical oceans have been considered to be less productive than those of the Temperate Zone because of certain environmental factors.

Comparative ecology of submersed grass beds in freshwater, estuarine, and marine environments1
Limnology and Oceanography, 1988Worldwide, there are 500–700 species of submersed angiosperms adapted to freshwater and estuarine environments compared with 50 species adapted to marine waters. In their evolution from freshwater ancestors, seagrasses have undergone extensive anatomical changes (e.g. reduction in floral and leaf structures, reduction of xylem tissue with a lacunal gas

Recent data demonstrating global increases in biologically damaging UV-B radiation raise the need for knowledge of how natural communities and ecosystems will respond to these environmental changes. These responses are likely to differ in terrestrial versus aquatic environments, and in freshwater versus marine environments due to fundamental ...
