Use of large Acacia trees by the cavity dwelling Black-tailed Tree Rat in the Southern Kalahari
2006
Recent extensive harvesting of large, often dead Acacia trees in arid savanna of southern Africa is cause for concern about the conservation status of the arid savanna and its animal community. We mapped vegetation and nests of the Black-tailed Tree Rat Thallomys nigricauda to assess the extent to which the rats depend on particular tree species and on the existence of dead, standing trees. The study was conducted in continuous Acacia woodland on the southern and eastern edge of the Kalahari, South Africa. Trees in which there were tree rat nests were compared with trees of similar size and vigour to identify the characteristics of nest sites. Spatial analysis of tree rat distribution was c…
Seaweed fails to prevent ocean acidification impact on foraminifera along a shallow-water CO2 gradient
2015
Ocean acidification causes biodiversity loss, alters ecosystems, and may impact food security, as shells of small organisms dissolve easily in corrosive waters. There is a suggestion that photosynthetic organisms could mitigate ocean acidification on a local scale, through seagrass protection or seaweed cultivation, as net ecosystem organic production raises the saturation state of calcium carbonate making seawater less corrosive. Here, we used a natural gradient in calcium carbonate saturation, caused by shallow-water CO2 seeps in the Mediterranean Sea, to assess whether seaweed that is resistant to acidification (Padina pavonica) could prevent adverse effects of acidification on epiphytic…
Ricerche tassonomiche sulle Capparaceae della Somalia: una nuova combinazione nel genere Boscia Lam.
1991
Lo studio dei tipi di Boscia tomentella Chiov. e Maerua mazzocchii (Chiov.) Chiov. ha dimostrato che si tratta di taxa conspecifici, correttamente inquadrabili nel genere Boscia. Sulla base delle regole nomenclaturali, viene quindi istituita la nuova combinazione Boscia mazzocchii (Chiov.) Fici et Kers, comb. nov.
