Reconstruction of Diadema mexicanum bioerosion impact on three Costa Rican Pacific coral reefs [PDF]

Revista de Biología Tropical, 2012
The 1982-83 El Niño event produced a high coral mortality (50-90%) in several localities in the Eastern Tropical Pacific, which resulted in an outbreak of the sea urchin populations of Diadema mexicanum A.

Species complex diversification by host plant use in an herbivorous insect: The source of Puerto Rican cactus mealybug pest and implications for biological control. [PDF]

Ecol Evol, 2020
Hypogeococcus pungens is a species complex native to South America. Some of its members are cactophilic, and one of them has been reported as a pest threatening cactus diversity in the Caribbean and North America. Using a combination of genome‐wide SNPs and mtDNA, we found that the complex comprises at least five different species, each strongly ...

Fiddler Crabs (Crustacea: Decapoda: Ocypodidae) From Coastal Ecuador and the Galápagos Islands: Species Descriptions and DNA Barcodes. [PDF]

Ecol Evol
Twenty‐five taxa were collected during the surveys, while two more were noted from the literature and museum collections; five are new to Ecuador. DNA sequences for cytochrome c oxidase–subunit 1 were obtained for 27 operational taxonomic units with three morphologically indistinguishable cryptic or pseudo‐cryptic taxa were also revealed.

Neutrophil β1 adrenoceptor blockade blunts stroke‐associated neuroinflammation

British Journal of Pharmacology, Volume 180, Issue 4, Page 459-478, February 2023., 2023
Background and Purpose Reperfusion therapy is the standard of care for ischaemic stroke; however, there is a need to identify new therapeutic targets able to ameliorate cerebral damage. Neutrophil β1 adrenoceptors (β1AR) have been linked to neutrophil migration during exacerbated inflammation.

Is Ocean Acidification Really a Threat to Marine Calcifiers? A Systematic Review and Meta‐Analysis of 980+ Studies Spanning Two Decades

Small, Volume 18, Issue 35, September 1, 2022., 2022
Marine calcifiers are widely believed to be impaired by ocean acidification, but this concept has been increasingly challenged by recent evidence. This systematic review and meta‐analysis of nearly 1000 studies reveal that many calcifiers are indeed more resistant to ocean acidification than initially thought, which can result from the positive effects

Allometry of Mexican hogfish (Bodianus diplotaenia) for predicting the body length of individuals from two pre‐Columbian sites in the Pearl Island archipelago (Panama)

International Journal of Osteoarchaeology, Volume 32, Issue 3, Page 669-681, May/June 2022., 2022
Abstract The Mexican hogfish (Osteichthyes: Labridae, Bodianus diplotaenia Gill, 1862) is widely distributed throughout the tropical eastern Pacific from the Gulf of California to northern Peru, including all oceanic islands. Artisanal fishers occasionally capture it today and its remains are recovered at pre‐Columbian dwelling sites along the Pacific ...

The widely distributed, edible seaweeds in Peru, Chondracanthus chamissoi and Chondracanthus chamissoi f. glomeratus (Gigartinaceae, Rhodophyta), are morphologically diverse but not phylogenetically distinct

Journal of the World Aquaculture Society, Volume 52, Issue 6, Page 1290-1311, December 2021., 2021
Abstract Chondracanthus chamissoi is part of the diet of coastal people from Peru and is exported dehydrated to Asian countries for direct consumption. Although it is considered endemic to Peru and Chile, its range has extended to distant regions, such as Korea, Japan, and France. Using morphological and molecular approaches, we examined specimens from

Natural ocean acidification at Papagayo upwelling system (north Pacific Costa Rica): implications for reef development [PDF]

Biogeosciences, 2018
Numerous experiments have shown that ocean acidification impedes coral calcification, but knowledge about in situ reef ecosystem response to ocean acidification is still scarce. Bahía Culebra, situated at the northern Pacific coast of Costa Rica, is a
