Dear MARMAM readers,   My coauthors and I are pleased to announce the publication of our study entitled "First report of signature whistles in an oceanic common bottlenose dolphin (Tursiops truncatus) population from Revillagigedo Archipelago, Mexico” in Marine Mammal Science:   Raul Rio, Hiram Rosales-Nanduca, Lucia A.

A total of 85% (199/233) of the recorded whistles were classified as stereotyped whistles and subsequently (bout analysis/SIGID) categorized into one of five SW types. External observers were in perfect agreement in classifying whistles into the adopted SW categorization. SWs represented 42% (98/233) of the repertoire. Overall, most whistle types were categorized as sine (80%; SW1, SW2, SW4, and SW5) with one downsweep (20%, SW3). Roca Partida Island had the highest number of SW types. Principal component analysis explained 77% of the total SWs variance, highlighting the importance of shape/contour variables to the SWs variance. The combined mean SWs acoustic parameters from Revillagigedo Archipelago were higher than that recorded in coastal regions, which may indicate there are differences between SWs of pelagic and coastal populations. However, further acoustic and ecological studies in the Archipelago are needed to clarify and expand our findings, to identify its members (Photo ID and SW Revillagigedo Catalog), and to investigate this topic at other oceanic islands.

Title: Abundance estimation, group dynamics, and residence patterns of Indian Ocean humpback dolphin (Sousa plumbea) in the Dayer?Nakhiloo Marine National Park, Northern Persian Gulf, Iran Authors: Nazanin Mohsenian, S?verine Methion, Hamed Moshiri, Shadi Karbalaei Hassan, Shaghayegh Afkhami, Mohammad Amin Tollab, Mahmod Sadeh, Gill T. Braulik, Bruno D?az L?pez AbstractThe Persian Gulf is positioned in the heart of the Middle East as one of the most critical water bodies. Indian Ocean humpback dolphins (Sousa plumbea) are distributed in nearshore waters and are therefore highly vulnerable to a variety of anthropogenic pressures. To our knowledge, there is a little information and data available about habitat use and abundance of this endangered species in Iranian waters. In the present study, baseline data about population size and site fidelity of Indian Ocean humpback dolphins in the Dayer-Nakhiloo Marine National Park in Northern Persian Gulf, Iran, has been explored for the first time. From March 2014 to December 2018, 127 boat-based surveys and 6436 km of survey effort were conducted. Overall, 127 groups of humpback dolphins were observed on 62% of the surveys. Humpback dolphin group size ranged from 1 to 14 individuals (mean 5.8 ? SE 0.3). Abundance estimates were calculated and fitted with open population models. Thirty (95%!   CI 22?38) humpback dolphins were estimated to inhabit the study area. There was a lack of seasonality in the occurrence of humpback dolphins and strong site fidelity within the Dayer-Nakhiloo Marine National Park. Most of the identified individuals used the study zone regularly (79.5%), while a smaller number were present less often. The results of this study provide important baseline information about humpback dolphin ecology in an area subject to significant anthropogenicpressures which can help to take effective conservation and management measures.
