Article
Full-text available
Increasing speed and magnitude of global change threaten the world’s biodiversity and particularly coral reef fishes. A better understanding of large-scale patterns and processes on coral reefs is essential to prevent fish biodiversity decline but it requires new monitoring approaches. Here, we use environmental DNA metabarcoding to reconstruct wel...
Article
Full-text available
Quantifying fish species diversity in rich tropical marine environments remains challenging. Environmental DNA (eDNA) metabarcoding is a promising tool to face this challenge through the filtering, amplification, and sequencing of DNA traces from water samples. However, because eDNA concentration is low in marine environments, the reliability of eD...

The habitat formed by the Callogorgia species, with their abundance and colony sizes, provides an important refuge for a variety of brittle stars which are recognized as the epibionts of octocorals in both shallow and deep environments. In such a relationship, ophiurans benefit directly from being elevated because they facilitate their feeding by s...
Article
Estuaries are characterized by a tidal regime and are strongly influenced by hydrodynamics and host diverse and highly dynamic habitats, from fresh, brackish, or saltwater to terrestrial, whose biodiversity is especially difficult to monitor. Here, we investigated the potential of environmental DNA (eDNA) metabarcoding, with three primer sets targe...
Article
Assessing the impact of global changes and protection effectiveness is a key step in monitoring marine fishes. Most traditional census methods are demanding or destructive. Nondisturbing and nonlethal approaches based on video and environmental DNA are alternatives to underwater visual census or fishing. However, their ability to detect multiple bi...

Article
Full-text available
• Monitoring large marine mammals is challenging due to their low abundances in general, an ability to move over large distances and wide geographical range sizes. • The distribution of the pygmy (Kogia breviceps) and dwarf (Kogia sima) sperm whales is informed by relatively rare sightings, which does not permit accurate estimates of their distribu...

Full-text available
The book presents the results of the expeditions carried out by Invemar between 2011-2018 to the North Pacific of Chocó to study the biodiversity on the shallow portion (0-40 m deep) of the rocky reefs, locally named riscales and morros. In total, 33 sites were explored across around 200 km of coastline between Cabo Corrientes and Cabo Marzo. 59 sp...

Full-text available
Environmental DNA (eDNA) analysis is a revolutionary method to monitor marine biodiversity from animal DNA traces. Examining the capacity of eDNA to provide accurate biodiversity measures in species‐rich ecosystems such as coral reefs is a prerequisite for their application in long‐term monitoring. Here, we surveyed two Colombian tropical marine re...

Fifteen morphotypes of deep-sea holothurians were documented by photography or videography at depths of 596–2,566 m, using Remote Operated Vehicles (ROV) video surveys and towed camera transects, during hydrocarbon exploratory activities in the Colombian Southern Caribbean. Most of the morphotypes were identified to the species level based on the i...

Rocky reefs of the northern Colombian Pacific (Chocó) are diverse ecosystems that are poorly studied. Echinoderms are one of the principal groups in these ecosystems with associations to different species, including benthic organisms in which they live and other species that use them as hosts. These relationships include fishes, sponges, seaweeds,...

Holothuria (Mertensiothuria) viridiaurantia sp. nov. is described based on specimens from rocky reefs of northern Chocó in the Colombian Pacific Ocean; however, it also occurs along the Eastern Pacific Ocean from Mexico and Panama. Although specimens from Mexico and Panama were previously identified as Holothuria (Mertensiothuria) hilla Lesson, 183...

Brittle stars are recognized as octocoral epizoic organisms, both in shallow and deep environments. In these relationships, ophiurans benefit directly by being elevated, facilitating their feeding by suspension, and passive protection by octocoral. However, the octocorals do not seem to benefit or be harmed by this relationship. During the Tumaco O...

Astrophorida is one of the most diverse (>820 species) and worldwide distributed orders of demosponges. These sponges are common colonizers of hard and soft-bottoms in a broad bathymetrical range. In hard-bottom habitats on the outer shelf and upper slope, astrophorids can dominate ecosystems in terms of abundance and biomass forming sponge grounds...

Is an elongated shape geoform that combines geological and biotic processes, via structural lifting through mud domes and via the colonization of coral formations. During an explora...

We investigated the current patterns of diversity by country and by class of echinoderms, and analyzed their biogeographical, depth, and habitat or substratum affinities, using the database of the appendix of this book. Traditionally, the area has been divided into five biogeographical Regions and nine Provinces that cover a wide climate range. Cur...

Colombia is recognized as a megadiverse country based primarily on terrestrial biodiversity. However, it has a coastline on the Caribbean Sea and Pacific Ocean, home to many marine ecosystems, which in many cases have not been investigated. As expected, the Caribbean and Pacific coasts of Colombia exhibit different geological, oceanographic, climat...

Holothuria arguinensis is reported for the first time on the south-eastern Spanish coast. One specimen of this species was identified in El Mojón (Alicante, Spain, 37°50′54.17″N 0°45′39.90″W). This finding widens the geographical range of H. arguinensis and demonstrates that its environmental requirements are changing. Future genetic studies in thi...

he echinoderms of Guam have become fairly well known over the years, as these large and conspicuous animals have been popular subjects for a variety of biological studies. The first written record is by Quoy & Gaimard (1834), who described Holothuria guamensis (now Actinopyga varians, Netchy & Paulay in prep.) and noted (but did not name) that five...

Sea cucumber stocks have been overfished in many countries from Indian and Pacific oceans as result of ever-increasing market demand, uncontrolled exploitation and/or inadequate fisheries management. The life-history traits of holothurians make them especially vulnerable to overfishing because they have low or infrequent recruitment, high longevity...

We assessed the genetic structure of populations of the widely distributed sea cucumber Holothuria (Holothuria) mammata Grube, 1840, and investigated the effects of marine barriers to gene flow and historical processes. Several potential genetic breaks were considered, which would separate the Atlantic and Mediterranean basins, the isolated Macaron...

This work investigates the systematics of the genus Holothuria in the Mediterranean Sea and Northeastern Atlantic in the light of a wider molecular phylogenetic hypothesis of Holothuriidae, and it also provides a time-scale for the family diversification using mitochondrial markers and the molecular clock hypothesis. The subgenera Holothuria and Ro...
