Reproductive strategies in loggerhead sea turtle : polyandry and polygyny in a Southwest Atlantic rookery.

Sea turtles are highly migratory and predominantly inhabit oceanic environments, which poses significant challenges to the study of their life cycles. Research has traditionally focused on nesting females, utilizing nest counts and mark-recapture methods, while male behavior remains understudied. To address this gap, previous studies have analyzed the genotypes of females and hatchlings to indirectly infer male genotypes and evaluate the extent of multiple paternity within populations.

Genetic variation and cryptic lineage among the sergestid shrimp (Decapoda).

The taxonomic status of the sergestid shrimp, has been questioned for several decades. No specific study has been performed thus far to resolve the incongruences. This species has a wide geographical range in the western Atlantic and is represented by two formally accepted subspecies: , distributed in North America, and , present in South America.
