AQUATIC ECOLOGY SECTION

Ecology of Vibrio mimicus in aquatic environments.

An environmental study was done to examine the prevalence of Vibrio mimicus in some aquatic environments of Dhaka, Bangladesh, and of Okayama, Japan. Water samples from Dhaka environments and water and plankton samples from Okayama environments were quantitatively as well as qualitatively analyzed throughout the seasons for V. mimicus. The organism was isolated from Bangladesh environments thro...

Special Section: Hierarchical Models in Avian Ecology

As spatial ecology, biogeography, and landscape ecology progress we are increasingly aware of how spatial and temporal scale structure ecological patterns and affect ecological processes (Wiens 1989). Advances in these fields have come from studies of a variety of taxa, particularly plants and insects (With 1994, Ludwig and Tongway 1995, Wondzell et al. 1996, McIntyre and Wiens 1999, Östman and...

Biomechanical Properties of Aquatic Plants: Implications for Hydraulic Engineering and Aquatic Ecology

Aquatic vegetation in rivers often modifies hydraulic resistance and can enhance seasonally occurring flooding. To which extent a plant constitutes an obstacle in the flow is strongly influenced by its biomechanical traits which determine the ability of plants to reconfigure in the flow, i.e. to adopt a shape that minimizes drag forces and hence to smooth the flow dynamics in and around submerg...

[Ecology of Vibrio cholerae serogroup 01 in aquatic environments].

The endemic and seasonal nature of cholera depends upon the survival of Vibrio cholerae 01 in a viable but not necessarily culturable state in ecologic niches in aquatic environments during interepidemic periods. To understand the ecology of V. cholerae it is necessary to know which aquatic ecosystems can harbor it and thus contribute to the endemic presence of cholera in Latin America. This ar...
