With increasing TP, a significant decline was observed in the species richness of zooplankton and submerged macrophytes, while for fish, phytoplankton and floatingleaved macrophytes, species richness was unimodally related to TP, all peaking at 0.1 – 0.4 mg P L − 1. The Shannon–Wiener and the Hur ...

Plitvice Lakes National Park
Plitvice Lakes National Park (Croatian: Nacionalni park Plitvička jezera, colloquial Plitvice, pronounced [plîtʋitse]) is one of the oldest national parks in Southeast Europe and the largest national park in Croatia. In 1979, Plitvice Lakes National Park was added to the UNESCO World Heritage register.The national park was founded in 1949 and is situated in the mountainous karst area of central Croatia, at the border to Bosnia and Herzegovina. The important north-south road connection, which passes through the national park area, connects the Croatian inland with the Adriatic coastal region.The protected area extends over 296.85 square kilometres (73,350 acres). About 90% of this area is part of Lika-Senj County, while the remaining 10% is part of Karlovac County.Each year, more than 1.1 million visitors are recorded. Entrance is subject to variable charges, up to 180 kuna or around $32USD per adult in peak season.
