A Comparison of Bottlenose Dolphin Whistles in the Atlantic Ocean: Factors Promoting Whistle Variation
Abstract Whistles are narrowband, frequency-modulated sounds produced by many cetaceans. Whistles are extensively studied in delphinids, where several factors have been proposed to explain between-
Cytochrome b and Bayesian inference of whale phylogeny.
Dogs, cats, and kin: a molecular species-level phylogeny of Carnivora.
A time-calibrated species-level phylogeny of bats (Chiroptera, Mammalia)
This work provides a cytochrome b genealogy of over 50% of bat species, and an analysis of divergence times, as tools for evolutionary and ecological studies that will be useful until more inclusive studies using multiple loci become available.
Phylogenetic review of tonal sound production in whales in relation to sociality
The results support the hypothesis that sociality influences the evolution of tonal sound complexity and the level of social and whistle complexity are correlated, suggesting that complex tonal sounds play an important role in social communication.
Phylogeny and conservation priorities of afrotherian mammals (Afrotheria, Mammalia)

A characterization of Guyana dolphin (Sotalia guianensis) whistles from Costa Rica: the importance of broadband recording systems.
It is concluded that equipment with an upper frequency limit of at least 50 kHz (150 kHz for harmonics) is required to capture the entire whistle repertoire of the Guyana dolphin.
The freshwater dolphin Inia geoffrensis geoffrensis produces high frequency whistles.
The recording of over 100 whistles from boto dolphins in the Yasunf River, Ecuador, provides conclusive evidence for whistle production in Inia geoffrensis ge offrensis, and has important implications for the evolution of whistles in Cetacea.
Patterns of cetacean sighting distribution in the Pacific exclusive economic zone of Costa Rica based on data collected from 1979-2001.
The distribution maps represent the first comprehensive representation of cetacean species that inhabit Costa Rican Pacific waters and provide essential base-line information that may be used to initiate conservation and management efforts of the habitats where these animals reproduce and forage.
