A new species of fungus belonging to the lethal genus Coelomomyces, C. neotropicus, is described and illustrated. It was found parasitizing larvae of two species of Culicidae, Culex pilosus and Aedes sp., in a lowland tropical wet forest swamp in northeast Costa Rica.

Magnetotactic algae of the genus Anisonema (Euglenophyceae) have been isolated from a coastal mangrove swamp in northeastern Brazil. The magnetotactic response is based on a permanent magnetic dipole moment per cell approximately 7 10(-10) emu. Each cell contains many magnetite (Fe(3)O(4)) particles organized in chains.

The red swamp crayfish (Procambarus clarkii) has been widely introduced into aquatic systems all around the world, triggering multiple impacts. In Doñana Natural Area, Abalario and the Biological Reserve of Doñana, Spain (one of the most important biodiversity reserves in Europe), the red swamp crayfish was first introduced in 1974 and expanded its range quickly through marsh habitat, but distr...

Macrofossil analysis of a composite 19 m long sediment core from Rano Raraku Lake (Easter Island) was related to litho-sedimentary and geochemical features of the sediment. Strong stratigraphical patterns are shown by indirect gradient analyses of the data. The good correspondence between the stratigraphical patterns derived from macrofossil (Correspondence Analysis) and sedimentary and geochem...

Southeast Asia's lowland dipterocarp forests experience supra-annual "mast" fruiting and flowering events, in which the majority of trees reproduce simultaneously at irregular intervals, with extensive intervening periods of very low primate food availability. This scarcity of food results in a negative energy balance and a reliance on "fallback foods" in some primate species. By contrast, ombr...

The article discusses issues related to the existing legal regulation of relations use and protection swamps. physical geographical features marshes as natural objects affecting peculiarities their protection, hydrological classification, ecological significance for sustainable functioning aquatic forest ecosystems are shown. Based on analysis current legislation defining procedure wetlands, pr...

Leaf size indices of the tree species in the peatland of Agusan del Sur in Mindanao in Philippines was examined to deduce the variation of forest structure and observed forest zonation.  Using raunkiaer and webb’s leaf size classification, the leaf morphometrics of seven tree species consistently found on the established sampling plots were determined.  The species includes Ternstroemia phi...

Water is a natural resource that very important for human life and other living things. Some of the water sources in Merauke district come from well or swamp. The generally blackish brown colour, has smell, taste. This study aimed to design purification device. method used this consisted preparation stage purifier design. second was construction device, last trial tool. materials were: alum, gr...

In various domains, such as computer games, robotics, and transportation networks, shortest paths may need to be found quickly. Search time can be significantly reduced if it is known which parts of the graph include “swamps”—areas that cannot lie on the only available shortest path, and can thus safely be pruned during search. We introduce an algorithm for detecting hierarchies of swamps, and ...
