This study documents for the first time the taxonomic composition of the nematode community and the number of free-living nematode species in the Lake Varano, Southern Adriatic Sea, Italy. The nematode community was mainly composed of species typical of fine sediments that usually prevail in transitional environments (TEs).

Lake Varano is a coastal lagoon located on the northern side of the Gargano National Park (Southern Adriatic Sea). It comprises an area of about 65 km2 and its water depth is about 4 m.

Transitional environments (TEs) are aquatic systems characterized by large fluctuations of physicochemical and geochemical variables, which may greatly affect the benthos. In particular, Adriatic Sea coast hosts a large amount of TEs, which range from the largest and most studied Lagoon of Venice, to wetlands, estuaries, embayments and ponds. All these habitats have been modified to meet human requirements for millennia and are currently under severe stress due to both anthropogenic activities and climate changes.
Of the 55 species identified in the present study, 20 are new records for the Italian coasts, 3 are new records for the Adriatic basin and 40 are reported for the first time for the Southern Adriatic sector. These data greatly increase the faunistic information available on the distribution of the marine Nematoda along the Italian coasts, and especially in the TE systems that are still poorly known environments.

Sediment samples were treated with a 7% MgCl2 aqueous solution to narcotize the fauna, fixed in a 4% formaldehyde solution in buffered sea-water, and stained with Rose Bengal. In the laboratory, the samples were rinsed with a gentle jet of fresh water through a 0.5mm sieve to remove the macrofaunal components. The residual sediment was then decanted, sieved 10 times through a 42μm mesh and centrifuged three times with Ludox HS30 (specific density 1.18) (Pfannkuche & Thiel, 1988). One hundred nematodes were randomly picked from each sample and mounted on permanent slides for taxonomic study (Seinhorst, 1959). The specimens were observed under Nomarski Differential Interference Contrast illumination (Optiphot-2 Nikon, 100x oil immersion objective) and identified by means of the NeMys online identification key (Vanaverbeke et al. 2005).
Sediment samples from 21 stations were collected on 22nd March 2012
Samples were collected using a modified model of Van Veen Grab
