2011
The locality of <em>Potamogeton berchtoldii</em> Fieber, the new species to the flora of Tajikistan (Middle Asia), together with its ecological conditions are presented. Additionally, the list of herbarium specimens of <em>P. pusillus</em> L. s. stricto gathered in Tajikistan and few specimens of <em>P. berchtoldii</em> collected from the area of adjacent countries are also provided. Taxonomical position of the species within the <em>Potamogeton pusillus</em> aggregation, the main morphological features of both taxa and possibility of finding other localities are discussed.
Aquatic Macrophytes Occurrence in Mediterranean Farm Ponds: Preliminary Investigations in North-Western Sicily (Italy)
2021
Mediterranean wetlands are severely affected by habitat degradation and related loss of biodiversity. In this scenario, the wide number of artificial farm ponds can play a significant role in the biodiversity conservation of aquatic flora. In the present contribution we show the preliminary results of a study on Mediterranean farm ponds of north-western Sicily (Italy), aimed to investigating the environmental factors linked to the occurrence of submerged macrophytes (vascular plants and charophytes). We studied the aquatic flora of 30 ponds and determined the chemical and isotopic composition of their water bodies on a subset of the most representative 10 sites. Results show that (1) farm p…
