African Mountain Thistles: Three New Genera in the Group.

The floras on the highest mountains in tropical eastern Africa are among the most unique floras in the world. Despite the exceptionally high concentration of endemic species, these floras remain understudied from an evolutionary point of view. In this study, we focus on the group (subtribe Carduinae) to unravel the evolutionary relationships of the species endemic to the tropical Afromontane and Afroalpine floras, aiming to improve the systematics of the group.

Repeatedly Northwards and Upwards: Southern African Grasslands Fuel the Colonization of the African Sky Islands in (Compositae).

The Afromontane and Afroalpine areas constitute some of the main biodiversity hotspots of Africa. They are particularly rich in plant endemics, but the biogeographic origins and evolutionary processes leading to this outstanding diversity are poorly understood. We performed phylogenomic and biogeographic analyses of one of the most species-rich plant genera in these mountains, (Compositae-Gnaphalieae).

Acute exposure to a commercial formulation of Azoxystrobin alters antioxidant enzymes and elicit damage in the aquatic macrophyte .

Azoxystrobin is a strobilurin of growing concern in aquatic environments because it is the most sold fungicide worldwide, however, the information available about its effect on aquatic non-target organisms is scarce. The objective of the present study was to evaluate potential physiological, biochemical, and genetic effects at environmentally relevant (1-10 μg/L) and elevated (100-500 μg/L) concentrations in the aquatic macrophyte exposed to the commercial formulation AMISTAR. Following an acute 24-h exposure, there were no effects of AMISTAR on photosynthetic pigments at any of the concentrations evaluated.

Evaluation of Growth, Photosynthetic Pigments and Genotoxicity in the Wetland Macrophyte Bidens laevis Exposed to Tebuconazole.

The fungicide tebuconazole (TBZ) has been used to prevent terrestrial fungi in agroecosystems, but it can also induce negative effects to non-targeted aquatic organisms, such as plants. The aim of the present work was to evaluate the potential cyto- and genotoxicity of TBZ in the aquatic macrophyte Bidens laevis, exposed to a range of concentrations of 0.1-100 µg/L.
