New methods for collecting Ostracoda (Crustacea) in stony sediments with methodological remarks on the separation of ostracods from sediment

Abstract

New methods for sampling ostracods are described specifically for hyporheic environments and coarse sediments (i.e., pebbles and rocks). The main module is a diaphragm pump that establishes an artificial current strong enough to force individuals from their habitat. Two other methods are presented for separating living ostracods from sediment samples taking advantage of their biological and physical properties: (1) emigration out of a basket; (2) harvesting ostracods floating on the water surface.

“…Besides, Külköylüoğlu (1999) collected species from February to November from springs of Nevada. Martín-Rubio et al (2005) reported species from Lake Caicedo de Yuso-Arreo (Spain) in January, February, March, April, June -August, and November when Scharf and Viehberg (2014) encountered species in February, April, June, July, September and October in Germany. The occurrence of the species in April from Lake Meyil (Konya, Turkey) (Akdemir 2008) and from May to January herein is now supported previously reported reproduction period of species.…”
