INTRODUCTION This study aims to investigate Nymphaea stellata (N. stellata) flower extract for antihyperglycaemic and antihyperlipidaemic effects in diabetic rats induced by alloxan. Its effect was compared with that of glibenclamide, a reference antidiabetic drug. METHODS Diabetic animals were randomly divided into five groups and treated orally with different doses (200, 300 and 400 mg/kg b...

Plant-insect interactions often are important for plant reproduction, but the outcome of these interactions may vary with environmental context. Pollinating seed predators have positive and negative effects on host plant reproduction, and the interaction outcome is predicted to vary with density or abundance of the partners. We studied the interaction between Silene stellata, an herbaceous pere...

UNLABELLED PREMISE OF THE STUDY The American Cross Timbers forest ecosystem runs from southeastern Kansas to Central Texas and is primarily composed of post oak (Quercus stellata). This old-growth forest currently occupies only about 2% of its ancestral range. To facilitate genetic research on this species, we developed microsatellite primers specific to post oak from reduced genomic librari...

Seaweeds have been introduced as an important sources of food and pharmaceutical active agents since last century. In this study, the chemical composition and functional characteristics of (common names) Nizamuddinia zanardinii and Iyengaria stellata, were investigated. The total carbohydrate and ash contents were the two most abundant components in these seaweeds but their crude lipid and fibe...

Identifying post-breeding migration and wintering distributions of migratory birds is important for understanding factors that may drive population dynamics. Red-throated Loons (Gavia stellata) are widely distributed across Alaska and currently have varying population trends, including some populations with recent periods of decline. To investigate population differentiation and the location of...

Hibiscadelphus stellatus H. Oppenheimer, Bustamente, & Perlman, sp. nov., a new, narrowly endemic species from West Maui, Hawaiian Islands is described, illustrated and its affinities and conservation status are discussed. It is currently known from three populations totaling 99 plants in Kaua`ula valley on leeward western Maui. It differs from H. wilderianus, its nearest congener, in its dense...
