Recent freshwater mussel research has resulted in rediscovery of several species presumed extinct. We report the rediscovery of Amblema plicata (Say, 1817) in 2019 from the Choctawhatchee River, Florida, USA. Amblema plicata has not been reported in the Choctawhatchee river basin since 1958, more than 61 years ago. This species was collected during the long-term monitoring of freshwater mussels in Florida streams. We provide genetic confirmation of our voucher identification using a DNA barcoding approach and discuss potential risks to A. plicata populations in the Choctawhatchee river basin.

Bird fauna long-term monitoring in the Romanian lower Prut river basin In the present paper, we give data on the bird' fauna's dynamic during the last 18 years in the Romanian Lower Prut River basin. This valley shelters a good level of the biodiversity being very well protected through the border status, but due the low level of the industrial development, too, despite an increasing of the human pressure in the last years. We recorded in this area some very rare breeding bird species for Romania - Platalea leucorodia, Plegadis falcinellus, Limosa limosa, Recurvirostra avosetta, Himantopus himantopus, Luscinia svecica, etc. but also some globally threatened species like Phalacrocorax pygmeus, Aythya nyroca or Crex crex. In this sector of the Prut River basin three Important Birds Areas (IBA) were delimited, all included in the "Romanian Nature 2000 Network".

The long-term monitoring of organophosphoric acid triesters started in 1976 in the Yodo River basin; Lake Biwa, Yodo River and the rivers in Osaka City. An extensive survey was also conducted in the Yamato River and Osaka Bay, Japan. This report presents the current levels and distributions of OPEs as well as the historical trend of TDCPP. Some or all of OPEs studied here have been detected in the entire water samples over the monitoring period. It was clear that OPEs were ubiquitous pollutants in the river and coastal waters. Total OPE levels ranged from 0.4 to 2.4 µgl−1 in the Yodo River basin, 2.4 to 12 µgl−1 in the rivers in Osaka City, 18 to 28 µgl−1 in the Yamato River basin and 0.1 to 1.3 µgl−1 in Osaka Bay. An apparent difference was found in the individual OPE level among the different water areas surveyed. In the Lake Biwa and the Yodo River, the predominant compound was TBXP followed by TCEP and TDCPP. The higher levels were observed for TBXP, TEP, TCPP and TCEP in the rivers in Osaka City. The highest TCPP level, which occupied more than 70% of OPEs' composition, was observed and the mean level reached to 13.1µgl−1 in the Yamato River. In Osaka Bay, 6 kinds of OPEs, except for TPP, TEHP and TCP, were found and the most prevalent compounds were TCEP and TBP. TDCPP had gradually increased in concentration in the Yodo River basin until 1987 from 1976 year by year. However, the reverse trend of TDCPP has been noticed during the last several years.
