BACKGROUND Geohelminths are parasites that stand out for their prevalence and wide distribution, depending on the soil for their transmission. AIMS The aim of this work was to evaluate the predatory capacity of the fungal isolate of the genus Duddingtonia (CG768) on third stage larvae (L3) of Ancylostoma spp. in beach sand under laboratory conditions. METHODS In the assay A five treatment g...

plant diversityis essential to maintain the health of planet's ecosystems. conservation of biodiversity is necessary for the ecological stability and productivity in natural ecosystems. the aim of this research was to study the biodiversity and richness of plant species (including trees, shrubs and grasses) related to the environmental factors (soil and physiography) in the forests of zagros, w...

This study aims to identify favorable oil–gas reservoir facies in the Chishan group of the Wubao fault zone (Gaoyou sag, Subei basin, China) using the methods of outcrops and cores observation, granularity analysis, scanning electron microscope, log data, etc. The results suggest that the Chishan group in the studied area mainly develops desert sedimentary system, and contains five kinds of fac...

Background. Beach soccer is one of the most well-known international sports in the world. The laws of the game were introduced by some associations and today they are covered by FIFA. There are also certain rules for the selection of beach soccer sand, but the specifications are too simple and rough. Thus, a wide range of sand types falls in the acceptable range of FIFA. Objectives. In this st...

The Husab Sand Lizard (Pedioplanis husabensis Berger-Dell’Mour and Mayer, 1989) is a recently described lacertid lizard endemic to a small region in the central Namib Desert. Although this species is of conservation concern, very little is known about how this lizard functions in its environment. We used the doubly labeled water method to measure the field energetics in this lizard species and ...

In a small shallow fjord with predominantly wind-driven circulation, larvae of the sand dollar Dendraster excentricus (Eschscholtz) do not persist for longer than 2 wk after a local population in the fjord spawns. Changes in distnbuhon and abundance of larval cohorts indicate that larvae are advected out of the fiord and thus contribute to a regional larval pool. A series of plankton samples at...
