Nutrient rich conditions often promote plant invasions, yet additions of non-nitrogen (N) nutrients may provide a novel approach for conserving native symbiotic N-fixing plants in otherwise N-limited ecosystems. Lupinus oreganus is a threatened N-fixing plant endemic to prairies in western Oregon and southwest Washington (USA). We tested the effect of non-N fertilizers on the growth, reproducti...

Factors that determine the relative abundance of bumblebee species remain poorly understood, rendering management of rare and declining species difficult. Studies of bumblebee communities in the Americas suggest that there are strong competitive interactions between species with similar length tongues, and that this competition determines the relative abundance of species. In contrast, in Europ...

Japanagromyza inferna Spencer is recorded for the first time from Brazil, in the North coast of the State of Rio de Janeiro, inducing galls in Centrosema virginianum L. (Fabaceae). The species is redescribed, with illustrations of male and female terminalia. A key to the identification of the Neotropical species of Japanagromyza Sasakawa is presented.

Fistulinella cinereoalba sp. nov., Austroboletus rostrupii, previously known from southeastern Asia, and Austroboletus festivus from Brazilian Amazonia are described for the first time from the Guiana Shield. These boletes were collected from tropical forests dominated by ectomycorrhizal Dicymbe spp. (Fabaceae subfam. Caesalpinioideae) in the Pakaraima Mountains of western Guyana.

Evaluation of green immature seeds from ten cultivars of white lupin (Lupinus albus L., Fabaceae), grown in two locations in Virginia (USA) during two years, indicated that physiological mature but green white lupin seeds contained 33 percent protein and 7 oil on dry weight basis.

The aphid genus Jacksonia Theobald is reported in China for the first time, from Shaanxi, with the description of a new species, Jacksonia gibbera Qiao, Li, Zhang & Su, sp. n., found on an unidentified plant belonging to the Leguminosae/Fabaceae. A key to species of Jacksonia is provided.

Chorebus (Stiphrocera) hexomyzae sp. n. (Hymenoptera, Braconidae, Alysiinae, Dacnusini) is described and illustrated. It was reared from twig galls of Hexomyza caraganae Gu (Diptera, Agromyzidae) on Caragana korshinskii Kom. f. (Fabaceae) in Ningxia and Inner Mongolia (NW China). A partial key to related or similar Chorebus species is provided.

INTRODUCTION Studies of the medical folklore of Northwestern Argentina are of great ethnomedicine value. The fruits of Geoffroea decorticans (Fabaceae) are used for both culinary and medical purpose (1). The aim of the present work was determined the total phenolic and flavonoid contents and antioxidant activities of extracts of chañar fruits. It was investigated the possible toxic effect on rats.

Abrus precatorius is one of the most important herb belonging to Fabaceae family. It is native to India and grows in tropical and subtropical areas of the world. It used as anti-diabetic, anti inflammatory, anti fertility, anti bacterial, anti fungal. Therefore the present review is aimed to highlight the botanical characters, its Phytochemical and pharmacological activities in various diseases.

Elaphomyces compleximurus sp. nov. and E. digitatus sp. nov. are described from the Pakaraima Mountains of Guyana. Macromorphological, micromorphological, habitat and DNA sequence data are provided for each new species. This is the first report of Elaphomyces ascomata associated with ectomycorrhizal members of the Fabaceae and also for the genus from the lowland South American tropics.
