Introduction: False killer whale (Pseudorca crassidens) is a tropical and subtropical social species that live in groups with individuals of mixed ages and sex classes. False killer whales have been documented since the late 1990s in Southwestern Costa Rica. Objective: To estimate the abundance of false killer whales in Osa Peninsula waters. Meth...

The aim of this assessment is to advance our understanding in the spatial ecology of the resident inshore and offshore population of bottlenose dolphins in Golfo Dulce (GD) and Osa Peninsula Waters (OPW). Our approach used niche-based models (Phillips et al., 2006, Thorne et al., 2012, Friedlaender et al., 2011), which provided details of how dolph...

Bottlenose dolphins (Tursiops truncatus) and pantropical spotted dolphins (Stenella attenuata) co-occur in Golfo Dulce, a fjord-like embayment located in the southern Pacific coast of Costa Rica. We evaluated if spatial overlap by these dolphin species is associated with similar environmental requirements. Presence-only models based on niche theory...

Golfo Dulce harbors an important resident population of inshore bottlenose dolphins (Tursiops truncatus) and migrating humpback whales (Megaptera novaeangliae, Northern and Southern Pacific populations). The present study offers a detailed spatial analysis of the utilization distribution of bottlenose dolphins (2005-2014: n= 407) and humpback whale...

Diversity of cetaceans in coastal seascape Golfo Dulce, Osa Peninsula, Costa Rica. Golfo Dulce is a fiord-lilke embayment located in the southern Pacific of Costa Rica, this coastal-marine ecosystem harbors an important wealth in marine biodiversity, including cetaceans. In this study we describe the cetacean community of Golfo Dulce, in relation t...

Whale shark, Rhincodon typus (Orectolobifoms: Rhincodontidae) feeding aggregations in Golfo Dulce, Osa Peninsula, Costa Rica. The zooplanktivorous whale shark (Rhincodon typus), is the largest living chondrichthyan and a cosmopolitan species, living in tropical, warm and temperate waters. It is considered vulnerable by the International Union for C...

Lacaziosis (also known as lobomycosis) is a chronic dermal disease caused by the fungal agent Lacazia loboi, which affects both humans and dolphins. Photographic data have been used to identify lacaziosis-like disease (LLD) among dolphins in the waters of North and South America, and here we report LLD in bottlenose dolphins Tursiops truncatus off...

Humpback whales (Megaptera novaeangliae) aggregate in winter breeding and calving grounds along continental margins, coastal islands, or archipelagos located in tropical waters. Migration to these breeding sites requires a long journey from northern feeding areas in temperate and circumpolar latitudes. The humpback whales habitat preference is gene...

... Photo ID analysis indicated the concurrent recapture of individuals from the OPW catalogue off Panama (LO data). Whereas a preliminary comparison with documented cases in Nicaragua has not yield any resighting of identified individuals (Pouplard et al., 2019), although a more in depth comparison is currently in progress. Based on the latter, we argue the potential occurrence of coastal population unit and oceanic island associated stock, as the one documented by Acevedo et al., (1997) off Isla del Coco. ...
... Furthermore, compared with other modelling approaches based on presence-only data, MaxEnt requires less data to build functional models, and it also provides more accurate predictions [18]. MaxEnt was applied in previous studies to obtain predictive results on bottlenose dolphins in the waters of Lampedusa Island [19], in the North-Eastern Atlantic [20], in the waters of the Osa Peninsula, and in Golfo Dulce, Costa Rica [21]. Moreover, there are also studies conducted using MaxEnt on Scopoli's shearwaters along the Tunisian [22] and Iberic [23] coasts, Yelkouan shearwaters [24], and European storm petrels along Spanish coasts [23]. ...
... Despite these limitations, isotope values from tissues have the advantage of being assimilated slowly in comparison to stomach contents, and so represent a consumer's trophic interaction over a much longer time period (Newsome et al., 2010;Walker and Macko, 1999). Stable isotope analysis has therefore become increasingly common in cetacean research to understand resource use and partitioning between sympatric species (Browning et al., 2014a;Kiszka et al., 2010;Méndez-Fernandez et al., 2013;Oviedo et al., 2018;Pinela and Borrell, 2010). ...
... The population and habitat use of the green turtle Chelonia mydas has been described by Chacón-Chaverri et al. Research on marine mammals has been emphasized with studies on humpback whales (Megaptera novaeangliae) by Bessesen (2015) and Herra-Miranda et al. (2016), the false killer whale Pseudorca crassidens (Sánchez-Robledo et al., 2020), dolphins (mainly the bottlenose dolphin Tursiops truncatus and the spotted dolphin Stenella attenuata) and other cetaceans (Acevedo, 1995;Acevedo-Gutiérrez, 1996;Acevedo & Burkhart,1998;Cubero-Pardo, 1998;Cubero-Pardo, 2007a;Cubero-Pardo, 2007b;Oviedo, 2007;Herra-Miranda et al., 2016;Moreno & Acevedo-Gutiérrez, 2016;Oviedo et al., 2018). Based on 943 sightings over a period of nine years the study by Oviedo et al. (2015) identified 12 species of cetaceans in Golfo Dulce. ...
... Lobomycosis in the bottlenose dolphin is as widespread as the geographical range of the bottlenose dolphin itself, with a prevalence as high as 16% [47][48][49][50][51][52][53][54][55][56][57][58]. Reports showed lobomycosis in bottlenose dolphins off the coasts of Florida, North Carolina (Atlantic Ocean) and Texas (Gulf of Mexico) in the United States, the coasts of Spain and France (Bay of Biscay), and the Brazilian Atlantic coast of Rio Grande do Sul state (Tramandi River) [47][48][49][50][51][52][53][54][55][56][57][58]. ...
... Despite the absence of any direct records of mating, it is very likely that mating occurs in Golfo Dulce, where competitive groups and singing males have been observed mainly in the sill area (Herra-Miranda et al. 2016). Our data add to the existing evidence that Golfo Dulce is a critical nursing and breeding area for humpback whales, which includes previous assessments and direct observations of calving (Márquez-Artavia et al. 2012;Bessesen 2015;Herra-Miranda et al. 2016). The high proportion of calves found at Golfo Dulce (54%) is similar to that in the adjacent calving areas of Chiriquí Gulf (52%, Rasmussen and Palacios 2013), Drake Bay and Isla del Canõ (58%;Vida Marina Foundation, unpubl. ...
