Dados Sobre o Projeto

The project is conducted by the Ukrainian Scientific Center of Ecology of the Sea (UkrSCES) in Odessa, Ukraine, with the expert support of Schmalhausen Institute of Zoology of National Academy of Sciences of Ukraine. The UkrSCES is the main institution of the Ministry of Ecology and Natural Resources of Ukraine in the field of marine ecological research. The project is aimed to increase knowledge about population structure and local distribution of the Black Sea cetaceans, among which there are endangered Black Sea bottlenose dolphins and harbour porpoises and vulnerable common dolphins.

Métodos de Amostragem

The linear transect survey (LTS) were designed according to standard principles of distance sampling (Buckland, 2004; Buckland et al., 2001). The survey platform was the yacht 8.8 m long; two pairs of observers, equipped by binoculars (10x40 and 10x50), changed after 30 minutes, and a dedicated operator recorded the data. The survey was conducted under good weather conditions (sea state less than 2 points of the Beaufort scale, visibility more than 5 km, zero precipitation). Boat speed was on average 9.5 km/h, at maximum 11 km/h. The observer eye height was 2.5 m. Tracks and coordinates were recorded, using the GPS navigator Garmin eTrex 30. Protocols of effort and registrations were filled in during the surveys. Species, group size, distance and angle from the moving boat were recorded at each encounter. In addition, behaviour types were recorded: fast movement, normal movement, feeding, etc., as well as behaviour in relation to the boat: avoiding, attraction or neutral. Individual photo identification was conducted from small boats, with a dedicated person responsible for protocol and coordinate logging. Tracks and coordinates were recorded, using the GPS navigator Garmin eTrex 30. Protocols of effort and registrations were filled in during the surveys.

Descrição dos passos do método:

1. LTS (Linear transect surveys) The linear transect survey (LTS) was designed according to standard principles of distance sampling (Buckland, 2004; Buckland et al., 2001). Density and abundance, cluster (group) density were estimated by analytical tools based on detection probability functions for distance sampling (Buckland et al., 2001), using Distance 7.0 software (Thomas et al., 2010). Photo identification. The basis of the method is the principle of individual identification with natural labels on the body and on the dorsal fin in particular (Würsig and Jefferson, 1990; Wilson et al., 1999; Urian et al., 2015).
