Tropical rainforest trees typically occur in low population densities and rely on animals for cross-pollination. It is of conservation interest therefore to understand how rainforest fragmentation may alter the pollination and breeding structure of remnant trees. Previous studies of the Amazonian tree Dinizia excelsa (Fabaceae) found African honeybees (Apis mellifera scutellata) as the predomin...

This contribution is the first part of a series designed to summarize present knowledge on fauna true bugs (Hemiptera: Heteroptera) Socotra Archipelago. A review aquatic, semiaquatic and shore infraorders Nepomorpha, Gerromorpha, Leptopodomorpha provided. Nine families 19 species are recorded from Island (including two marine off-shore species). The following new records given: Micronecta eupom...

cultivation of annual medics is a way to increase producing of forage with a better quality, to increase the quantity of producing forage in low yield drylands, and to assisst establishing pasture. this study was conducted in order to investigate the adaptation and determination of quantitative and qualitative characteristics of three species of annual medics. the experimnet was conducted in a ...

Studies were undertaken to determine the impact of environmental variables temperature (12.5/9.5, 20/17, 27/24 °C day/night) and soil moisture (100, 50% WHC), their interaction with Phoma medicaginis infection, on production phytoestrogen coumestrol in annual Medicago rugosa cv. Paraponto M. scutellata Sava. Disease factors measured included leaf disease incidence/severity, petiole/stem yellowi...

Abstract Relay intercropping of subsidiary legumes with durum wheat (living mulch) can be a viable option to support ecological weed control and optimize nutrient cycling in cereal-based cropping systems. However, the lack knowledge on suitable legume species is often identified as main bottleneck for successful application living mulches. This study aimed evaluate suitability 12 different rela...

Recent large-scale mortality of honeybee colonies is believed to be caused by multiple interactions between diseases, parasites, pesticide exposure, and other stress factors. To test whether a dual challenge has an additive effect in reducing survival, we experimentally stimulated the immune system of caged Apis mellifera scutellata workers from six colonies by injecting saline or Escherichia c...
