In the wilds of Africa, when it’s time for a family of elephants gathered at a watering hole to leave, the matriarch of the group gives the “let’s-go rumble” — as it’s referred to in scientific literature — kicking off a coordinated and well-timed conversation, of sorts, between the leaders of the clan. First, the head honcho moves away from the group, turns her back and gives a long, slightly ...

phytoplanktons are the first bio- indicators of pollution in aquatic ecosystems. phytoplankton assemblage and aquatic ecosystems are always influenced by environmental factors therefore these environmental changes and threats must be understood in any ecosystem. phytoplankton are inexpensive and readily available bio- indicators. in the present study, phytoplankton were used to study the sefid ...

We evaluated the influence of Parkia platycephala on plant assemblages under its crown and surrounding areas in a disturbed Brazilian Savanna, as well effects aqueous extracts leaves germination development three species, hypothesis that P. might work nurse species. Eleven direct (ADIs) indirect (AIIs) 11 control (COs) were delineated. All tree shrub species present these areas, including seedl...

When Users fires a query they want relevancy in obtained results.

The effect of weed management that targets the seed stage on subsequent life stages is largely unknown. Post-dispersal predation reduces number seeds from soil surface before contribute to seedbank. Density-dependent processes can mitigate in stages. In this study, we tested if (i) targeting affects seedling stage; (ii) density-dependent mortality partly compensates abundance; and (iii) magnitu...

abstract pythium aphanidermatum is one of the most important agent of root and foot rot of cucumber, particularly in the warm humid climate. induction of host resistance by microorganisms or by the synthetic compounds is recently considered as one of the biological control method of disease. trichoderma harzianum bi is a good candidate for induction of resistance in plant against diseases. the ...

Rhizobia induce root nodules and fix atmospheric N2 for most legume species in exchange for carbon. However, the diverse endophytic non-rhizobial bacteria in legume nodules that co-exist with rhizobia are often ignored because they are difficult to cultivate using routine cultivation approaches. To enhance our understanding of the incidence and diversity of legume-bacteria associations, a high-...
