We studied the settlement patterns of three Caribbean coral reef fishes in three different habitat types: mangroves, seagrass beds, and coral reefs. The settlement patterns of the three species were n...
As a way to escape from adverse conditions, many zooplankton populations produce diapausing eggs that accumulate in the sediments and hatch when suitable environmental conditions are restored. While b...
Habitat restriction for otters living in a small part of the Kızılırmak River occurred due mainly to 3 causes: dam construction at the upper end, heavy pollution by oil refinery effluen...
At Hook Ridge hydrothermal vent, a new species of Sclerolinum (Monilifera, Siboglinidae) was found at a water depth of 1,045 m. On the basis of investigations of multicores and gravity cores, the spec...
In this research, which was carried out between August 1995 and July 1997 in an area that embraces Lakes Mogan and Eymir, Imrahor Valley and the Gölbaşı district of Ankara province, the...
With field, laboratory, and modeling approaches, we examined the interplay among habitat structure, intraguild predation (IGP), and parasitism in an ongoing species invasion. Native Gammarus du...
Three-dimensional modeling of lake morphometry enables the calculation of lake volume, planar surface area, and basin surface area, which are critical components of a conceptual model of how planktic...
Low numbers of mysids in eutrophic lakes have usually been related to their poor tolerance to low oxygen. In eutrophic Lake Hiidenvesi, we studied the possibility that water quality indirectly affects...
We investigated the importance of snowmelt as an organizing factor for epilithic microalgae in a high-altitude montane stream during 3 yr (1995-1997) of differing melt characteristics. Changes in alga...
The classic approach for habitat preference of big games is to compare dung density in two different site such as in two habitat types and aspects, or in two altitute or slope classes. Whereas, animal...
