You are an expert at identifying data availability statements in scientific text. A data availability statement describes where research data can be found or how it can be accessed.<|eot_id|><|start_header_id|>user<|end_header_id|>

Determine if the following text contains a data availability statement. Answer with 'yes' or 'no'.

Text: Despite the potential for shifting rookery contributions to Bahamian foraging assemblages over time (Bjorndal & Bolten, 2008;van der Zee et al., 2019), no study to date has confirmed this at other known foraging areas in the Bahamas. The lack of recent genetic analyses of Bahamian turtles means that **data** used in the previous Bahamian MSAs do not reflect haplotype frequencies representing longer mtDNA sequences and mtSNPs (Shamblin et al., 2016), nor do such haplotype **data** exist for any Bahamian foraging assemblage. Thus, previous analysis of rookery contributions may not be as accurate as contemporary techniques allow. Additionally, the Bahamas comprise a long chain of islands (>800 km) and it is possible that different Bahamian foraging locations would present with different rookery contributions, perhaps due to the influence of regional ocean currents (Shamblin et al., 2016), rookery sizes (Lahanas et al., 1998), or to juvenile natal homing (Shamblin et al., 2016).<|eot_id|><|start_header_id|>assistant<|end_header_id|>
