Marine mammals can play important ecological roles in aquatic ecosystems, and their presence be key to community structure function. Consequently, marine are often considered indicators of ecosystem health flagship species. Yet, historical population declines caused by exploitation, additional current threats, such as climate change, fisheries bycatch, pollution maritime development, continue impact many mammal species, at least 25% classified threatened (Critically Endangered, Endangered or...
Considerable uncertainty exists regarding the migratory destinations of humpback whales (Megaptera novaeangliae) from Antarctic Peninsula region and breeding grounds off coasts South America. Evidence is presented on patterns based upon movements individuals identified by natural markings as part a large-scale international collaboration. Recapture rates were compared between animals low latitude calving areas along northeastern (n=288) northwestern (n=325) margins America with those in...
We succinctly review and document new cases of diseases the skin skeletal system external traumata in cetaceans from Ecuador, Colombia, Peru, Chile, Argentina, Uruguay, Brazil, Venezuela. The survey revealed 590 diagnosed with a significant pathology, injury or malformation on total 7635 specimens 12 odontocete species examined observed 1984-2007. Tattoo disease (TSD), lobomycosis-like (LLD) cutaneous unknown aetiology seem to be emerging several populations. TSD was confirmed eight SE...
Cetacean sighting data collected under various programmes in Colombian Pacific waters were collated with the goal of assessing distribution and abundance patterns all species occurring exclusive economic zone (EEZ). Distribution maps are presented for 19 one genus based on 603 sightings between 1986 2008. Ordered by frequency, these were: humpback whale (Megaptera novaeangliae); striped dolphin (Stenella coeruleoalba); common bottlenose (Tursiops truncatus); pantropical spotted attenuata);...
Dolphin hunting for fishing bait in Bahía Solano, Chocó, Colombia, was evaluated during eight months, between July 2005 and April 2006. Interviews were conducted with 122 fishermen (18.2% of the registered zone), who cover at most 890km2 when (approximately 2.3% Pacific Territorial Sea Colombia), data obtained from landings a company. Only using longlines (37.3%) confirmed dolphins as bait. It not possible to obtain additional information about date, specific location or dolphin species, but...
Abstract During the austral winter, G-stock humpback whales, Megaptera novaeangliae, migrate to Tropical Eastern Pacific breed. To analyse if whale migration times have changed over time, we analysed 31 years (1988–2018) of arrival and departure Gorgona National Park, Colombia, an important breeding site. this period, whales significantly their coming now earlier, but time has not significantly. Hence, stay 1 month longer than ago. Humpbacks arrived in at earliest during beginning May stayed...
We report on the epidemiology of lobomycosis-like disease (LLD), a cutaneous disorder evoking lobomycosis, in 658 common bottlenose dolphins Tursiops truncatus from South America and 94 Indo-Pacific T. aduncus southern Africa. Photographs stranding records 387 inshore residents, 60 non-residents 305 specimens undetermined origin (inshore offshore) were examined for presence LLD lesions 2004 to 2015. Seventeen 3 1 dolphin unknown residence status positive. appeared as single or multiple,...
During the whale-watching season of 2008, 6,663 whale watchers and 267 boat trips were recorded in Bahía Málaga, Colombia. Forty-four percent humpback pods sighted area approached by boats. Operators 2008 did not comply with Colombian guidelines during most encounters. The modal distance between whales boats was 50 m. Ninety-four too fast (>3 knots), 78.6% them mother–calf pods. On average, a pod observed for 42.6 minutes (SD 33.1), more than one 60.2% cases. As consequence boats'...
Wild animals are captured or taken opportunistically, and the meat, body parts, and/or eggs consumed for local subsistence used traditional purposes to some extent across most of world, particularly in tropics subtropics. The consumption aquatic is widespread, places has been sustained millennia, can be an important source nutrition, income, cultural identity communities. Yet, economic opportunities exploit wildlife at higher levels have led unsustainable exploitation species. In literature,...
Abstract Humpback whales ( Megaptera novaeangliae ) are a cosmopolitan species and perform long annual migrations between low-latitude breeding areas high-latitude feeding areas. Their populations appear to be spatially genetically segregated due long-term, maternally inherited fidelity natal In the Southern Hemisphere, some humpback whale mix in Ocean waters summer, but very little movement Pacific Atlantic has been identified date, suggesting these constituted an oceanic boundary distinct...
Southeast Pacific humpback whales (Megaptera novaeangliae) migrate annually to breeding grounds in Machalilla, Ecuador, and Uramba Bahía Málaga, Colombia. This species usually displays a black/ grey body colouration with its dorsal caudal fins exposed above water. Between 2005 2023, these regions were studied photographed on 1,627 days. Results indicated that 29 have novel markings, including white spots, irregular circles sinuous lines, which resemble the paintings of 20th Century artist...
Introduction: Proteinases and proteinase inhibitors have been described to play a role in autoimmune skin blistering diseases.We studied lesional biopsies from patients affected by several diseases for proteinases inhibitors.Methods: We utilized immunohistochemistry evaluate α-1-antitrypsin, human matrix metalloproteinase 9 (MMP9), tissue inhibitor of metalloproteinases 1 (TIMP-1), metallothionein urokinase type plasminogen activator receptor (uPAR).We tested 30 endemic pemphigus, controls...
Introducción: Los mamíferos marinos están siendo afectados por diferentes amenazas que causan un efecto negativo a las especies o poblaciones. Para mitigar estos impactos se requiere establecer para cada especie la variación espacial y temporal de estas amenazas. Objetivo: realizar una visualización cuantitativa afectan en Colombia últimas tres décadas, e identificar acciones necesarias dichas Métodos: En el presente estudio realizó revisión georreferenciación documentadas los presentes (35...
Uramba Bahía Málaga Natural National Park is one of the most important places visited by tourists to see humpback whales (Megaptera novaeangliae) in Colombia. Humpback arrive from Southern Chile and Antarctic Peninsula every year between May December reproduce, give birth rear calves. To evaluate current state whale-watching we analyzed tourist visitation data 2011 2019 during peak season (July–October), week October 2020. We found that activity has increased considerably. In 2019, 21,186...
Se registraron los primeros avistamientos de elefantes marinos, probablemente marinos del sur, Mirounga leonina, en la costa Pacífica Colombia. Un juvenil macho fue registrado las playas Piangüita y Magüipi (Valle Cauca), 23 al 25 enero 2018. Días después, el 22 febrero 2018, se reportó un macho, aparentemente mismo individuo, más norte playa Guachalito (Chocó). Luego, entre 29 diciembre 2019 20 2020, El Medio, desembocadura río Yurumanguí avistó grupo tres individuos subadultos; este...

Sightings of pinnipeds in Colombian waters the Pacific Ocean have sporadically been reported since 1970. Despite region (CPR) not being within their typical distribution range, six pinniped species—the Galápagos fur seal (Arctocephalus galapagoensis), sea lion (Zalophus wollebaeki), South American australis), (Otaria byronia), Juan Fernández philippii), and southern elephant (Mirounga leonina)—have recorded recent times. This study presents an overall systematic review sightings strandings...
