Health status and morphometrics of Galápagos magnificent frigatebirds (Fregata magnificens magnificens) determined by hematology, biochemistry, blood gas, and physical examination
The magnificent frigatebird (Fregata magnificens; MFB) is a seabird found in the Atlantic and Pacific Oceans. In the Galápagos Islands, the endemic subspecies Fregata magnificens magnificens inhabits the archipelago. This study presents, for the first time, the hematological and blood biochemical values of this population in the region.
Canine vector-borne parasites in the Galapágos
Endemic species of the Galápagos Islands are vulnerable to newly introduced pathogens, often transmitted through invasive hosts. One example is invasive parasitic arthropods, whose evolutionary success is linked to their association with domestic animals present in the archipelago. This interaction poses a significant risk, as these parasites can switch hosts and facilitate pathogen transmission between domestic and wild species.
Ontogenetic feeding shifts in two thresher shark species in the Galapagos Marine
Thresher sharks are key predators in the marine ecosystems of the Tropical Pacific Ocean, playing a fundamental role in maintaining ecological balance. They primarily feed on squid and small fish. This study aims to assess possible ontogenetic changes in the feeding habits and habitat use of two thresher shark species (Alopias pelagicus) and (Alopias superciliosus) inhabiting the Galápagos Marine Reserve (GMR), aspects that remain poorly understood in the region.
Molecular Discovery of Filarial Nematode DNA in an Endangered Wild Pinniped (Galapagos Sea Lion, Zalophus wollebaeki)
Environmental changes contribute to the arrival of non-native species and their pathogens in sensitive ecosystems such as the Galápagos Islands. This poses a significant risk to the archipelago’s unique species, including the Galápagos sea lion (Zalophus wollebaeki), an endemic and endangered animal that faces the threat of contracting diseases from introduced domestic animals.
Commentary: “Addressing illegal longlining and ghost fishing in the Galapagos marine reserve: an overview of challenges and potential solutions”
The commentary on the article “Addressing illegal longlining and ghost fishing in the Galapagos marine reserve: an overview of challenges and potential solutions” by Alex Hearn and Santiago Bucaram questions the proposal to develop an open water tuna fishery, warning about the risks of legalizing harmful fishing practices for the marine ecosystem. Additionally, they analyze the challenges faced by the Galapagos due to the use of illegal longlines.
Assessing economic losses in artisanal fisheries from marine plastic pollution in coastal Ecuador and Peru
This study reveals that the artisanal fishing sector along the coastal regions of Ecuador (excluding Galapagos) and Peru faces significant economic losses due to the considerable presence of marine plastic debris which directly impacts productivity.
Nutrient enrichment can increase the thermal performance of Galápagos seaweeds
This study, published in Marine Ecology Progress Series, examines how nutrient availability can help marine macroalgae in the Galápagos Islands better adapt to higher temperatures—a challenge they face due to climate change. Macroalgae are essential aquatic plants for marine ecosystems as they provide food and shelter for many species. However, their ability to survive and thrive largely depends on environmental conditions, such as the amount of nutrients in the water.
Ladybird Beetle Diversity in Natural and Human-Modified Habitats in the San Cristóbal Island, Galápagos, Ecuador
This study investigates the diversity of ladybird beetles (Coccinellidae) on San Cristóbal Island in the Galápagos Archipelago. Researchers recorded 19 species, including four previously documented (two endemic and two native) and nine potentially native species reported for the first time. Endemic species, such as Psyllobora bisigma and Scymnobius scalesius, were rare and confined to native forests, while native species like Cycloneda sanguinea showed adaptability to various habitats, including urban and agricultural areas.
Assessing the chemical landscape of the Galápagos Marine Reserve
The Galápagos Marine Reserve (GMR), famous for its incredible biodiversity, faces growing threats from chemical pollution like plastics, oils, pesticides, and heavy metals. The unique location of the Galápagos, where major ocean currents meet under intense sunlight, allows pollutants to flow in and spread.
From Prison Islands to Island Paradises: Are Violent Histories Being Overwritten with Nature-Based Tourism Imaginaries?
This article explores the transformation of former prison islands in Latin America—specifically Isabela (Galápagos), Coiba (Panama), and Gorgona (Colombia)—into nature-based ecotourism destinations. Originally used for exiling criminals, political prisoners, and other marginalized individuals, these isolated islands were chosen for their remote locations and difficult conditions, which made them suitable sites for confinement. However, as these prisons closed, new conservation and ecotourism initiatives developed, focusing on the islands’ natural beauty and biodiversity.
