Dear colleagues, We are pleased to announce our new publication:
LAURA VÁZQUEZ-CASTÁN, ARTURO SERRANO, MARISELA LÓPEZ-ORTEGA, JOSÉ A. GALINDO, MIGUEL A. DÍAZ-ARREDONDO & ASENCIÓN CAPISTRÁN-BARRADAS. 2014. IS THE NORTHERN-CENTRAL COAST OF VERACRUZ, MEXICO AN IMPORTANT AREA FOR BOTTLENOSE DOLPHINS (Tursiops truncatus Montagu, 1821)? Thalassas. 30(2): 57-64. Abstract: The northern and central coasts of the state of Veracruz are inhabited by a great variety of organisms due to its high primary productivity. The bottlenose dolphin (Tursiops truncatus Montagu, 1821) is one of the most charismatic species of this area. The purpose of this study was to determine the density and abundance of bottlenose dolphins on the northern and central coasts of Veracruz. The study area was subdivided into three zones, each housing a bottlenose dolphin population: Tamiahua, Tuxpan and Nautla. Distance sampling methodology was used to estimate dolphin density and abundance. In total, 89 surveys were conducted, totalizing 392.5 h of survey effort and an area sampled of 7,430 km2. Dolphins were sighted during 59 surveys, and of the 950 animals observed, 532 were determined to be unique individuals based on photo-identification. The abundance estimated for the entire study area is 2,632 dolphins (CV= 10.37%), with a density of 0.35 dolphin/km2 (CV= 10.37%), and density group of 0.35 group/km2 (CV= 10.37%). The results indicate that even though the study area is small it supports a larger density of bottlenose dolphins than the surrounding waters and may represent an important bottlenose dolphin conservation area in the Gulf of Mexico.
