Habitat richness

Species (habitat) richness was thus compiled on a 1-km2 basis for six taxonomic and life history groupings of species along with regional habitat importance ratings (Myers et al., 2001). The six species groupings were mammals, birds, amphibians, snakes and lizards, turtles, and fishes as p =... 

Measurement of contaminants in fish has concentrated on muscle tissue since the aim has generally been to protect the health of the consumer rather than that of the fish. Endocrine tissue such as the gonads has been much more rarely examined, while data for adrenal, thyroid and pituitary levels are virtually non-existent. More data are available for the liver, as a lipid rich tissue and the major site of xenobiotic catabolism, but the concentrations have rarely been related to its capacity to produce vitellogenin or metabolise endogenous hormones. Tissue concentrations of a wide range of chemicals, are at a level which suggests that, either alone or in combination, they will cause significant endocrine disruption in fish in many polluted habitats. 

A balanced landscape needs waterbodies. These should be designed to have shallow margins to provide the appropriate conditions for wetland planting which, in turn, provide the balanced habitats for a rich wetland ecosystem.

Beetles (Coleoptera) comprise the most species-rich insect order. About 350,000 species have been described today, about 10% of the estimated actual amount. Apart from open oceans, beetles are colonizing almost every habitat and are able... 

Teeming with iife A flowering meadow is a rich habitat for wildlife many grasses are food plants for caterpillars, without which we would have no butterflies. 

Substrate types characterizing these habitats included surfaces of dead coral, fine and coarse sands, organically rich mud-sand mixtures, wood and steel surfaces on wrecked ships, algal mats, attached macroalgae, and seagrass beds. Water depths at the various sites ranged from 0.2 to 25 meters.
