The Gulf of California (GC) is a semi-closed sea in the Tropical Eastern Pacific and is recognised as a highly diverse marine ecosystem. Despite this status, this region is still poorly studied in comparison to other marine hotspots. To start filling this gap, we attempt to provide a global overview of reef-fish diversity around the numerous islands of the region. We evaluated species richness, the abundance and biomass, and the functional diversity of the fish assemblages for the major islands of the GC. We first highlight that the southwestern part of the central GC is the hotspot of reef-fishes diversity within the GC, in terms of species richness, functional diversity, and fish abundance. We then found out an important functional divergence between...

An osteometric approach to reconstruct the length and weight of Lutjanus argentiventris (Perciformes: Lujtanidae) for archaeological and ecological purposes
Provedor de dados: 83
Autores: Martínez-Polanco,María Fernanda; Béarez,Philippe.
ABSTRACT Lutjanus argentiventris presents a large intertropical distribution within the Eastern Pacific, which is as important to fisheries now as it was in the pre-Hispanic period. The purpose of this article is to present an allometric model that enables the size and weight of L. argentiventris to be predicted, using the isolated bones found in archaeological and paleontological contexts or the stomach contents of ichthyophagous species. A modern collection of L. argentiventris from Ecuador was used, composed of 37 individuals covering a wide range of sizes and weights. The total length (TL), standard length (SL), and total fresh weight (W) of each individual was gathered. The TL of the sample ranged between 210 and 760 mm, the SL between 164 and 627 mm...

Ecosystems services vulnerability of Uramba Marine Protected Area
Provedor de dados: 50
Autores: Uribe-Castañeda,Natalia; Satizabal,Carlos Andrés; Herrera Orozco,Leonardo; Cantera Kintz,Jaime Ricardo.
ABSTRACT Systems of Uramba Marine Protected Area (MPA), like marine and coastal systems worldwide, sustain a great variety of ecosystem services (ES) (i.e. coastal protection, climate regulation, or food provision, etc.). Anthropogenic and natural stressors (i.e. coastal erosion, sea level rise, or overfishing, etc.) can transform, degrade, or limit the supply of ecosystem services. This study explores the vulnerability of Uramba MPA ecosystem services to anthropogenic and natural stressors. Stressors and ecosystems services were characterized by a literature review, an expert’s workshop, fieldtrips for validation, and georeferencing. To calculate the vulnerability of ecosystem services, the magnitude of each stressor, their risks, and their resilience...

CONFIRMATION OF THE OCCURRENCE OF THE CORAL PAVONA CHIRIQUIENSIS GLYNN, MATÉ AND STEMANN (CNIDARIA: ANTHOZOA: AGARICIIDAE) IN THE COLOMBIAN PACIFIC
Provedor de dados: 50
Autores: Zapata,Fernando A; Rodríguez-Ramírez,Alberto; Rodríguez-Moreno,Melina; Muñoz,Carlos G; López-Victoria,Mateo.
El género Pavona comprende 18 especies de las cuales Pavona chiriquiensis ha sido recientemente descrita y registrada en varias localidades del Pacífico oriental tropical. A partir de observaciones y colecciones realizadas en arrecifes de las islas Gorgona y Malpelo entre 1999 y 2005 se confirma su presencia en Colombia. El tardío registro de P. chiriquiensis en estas islas pudo ser debido a su similitud y confusión con P. varians, o a su reciente colonización del Pacífico colombiano.

Somatic growth rates of the Hawksbill Turtle, Eretmochelys imbricata, in Gorgona Natural National Park, Colombia, between 2004 and 2018
Provedor de dados: 50
Autores: Cañas-Uribe,Mariana; Payán,Luis F.; Amorocho,Diego F.; Páez,Vivian P.
ABSTRACT The Hawksbill Turtle, Eretmochelys imbricata, is globally assessed as Critically Endangered, and information in the Eastern Pacific Ocean is limited. For this reason, this investigation evaluated the somatic growth rates in an immature hawksbill sea turtle aggregation using capture-mark-recapture on the coral reefs at Playa Blanca and La Azufrada in the Gorgona Natural National Park, Colombia. Between 2004 and 2018, we made 89 captures of 49 hawksbill individuals. The mean curved carapace length (CCL) obtained was 41.6 cm (range 32-58 cm), and the mean straight-line carapace length (SCL) was 39.1 cm (range 30.0-54.1 cm), showing these reefs to be critical foraging grounds for immature individuals. The mean body condition index was 1.3 (range...

Filling a gap: first record of the shell-less neritacean gastropod Titiscania limacina Bergh, 1890 in Colombia
Provedor de dados: 50
Autores: Londoño-Cruz,Edgardo.
ABSTRACT Recording marine biodiversity is a fundamental task and species distributions are at the very core of it. This paper is the first report of Titiscania limacina, a shell-less neritacean, in Colombia. This species was recorded in the intertidal of a rocky ecosystem at Gorgona National Natural Park, Pacific coast. This discovery fills a gap of this species distribution in the Tropical Eastern Pacific and calls attention to biodiversity monitoring, given the potential of this understudied Colombian coast to produce more and interesting findings of new species for the region, in particular, or for science, in general.
