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

open access: yesInternational 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

open access: yesJournal 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

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

open access: yesEcology and Evolution, Volume 10, Issue 19, Page 10463-10480, October 2020., 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 ...

Resistance, resilience, and vulnerability of social‐ecological systems to hurricanes in Puerto Rico

open access: yesEcosphere, Volume 11, Issue 10, October 2020., 2020
Abstract Subject to hurricane disturbance for millennia, natural ecosystems of Puerto Rico exhibit clear patterns of resistance (e.g., many tree species have little immediate storm‐related mortality) and resilience (e.g., leaf litterfall and stream chemistry returned to pre‐hurricane levels in as little as five years).

Origin of Low-26Al/27Al Corundum/Hibonite Inclusions in Meteorites

open access: yesThe Astrophysical Journal, 2023
Most meteoritic calcium-rich, aluminum-rich inclusions formed from a reservoir with ^26 Al/ ^27 Al ≈ 5 × 10 ^−5 , but some record lower ${({}^{26}\mathrm{Al}/{}^{27}\mathrm{Al})}_{0}$ , demanding they sampled a reservoir without live ^26 Al.

Genetic composition and origin of juvenile green turtles foraging at Culebra, Puerto Rico, as revealed by mtDNA

open access: yes, 2017
Marine migratory species encounter a range of threats as they move through coastal and oceanic zones. Understanding the connectivity and dispersal patterns of such species is critical to their effective conservation. Here we analyzed the temporal genetic

Experimental Verification of Cavity-Flow Wall Effects and Correction Rules [PDF]

open access: yes, 1970
This report is intended as a companion to Report No. E-111A.5, "Wall Efects in Cavity Flows", by Wu, Whitney and Lin. Some simple rules for the correction of wall effect are derived from that theoretical study.

Medusas (Cnidaria: Hydrozoa) de una zona de afloramiento costero, Bahía Culebra, Pacífico, Costa Rica

open access: yes, 2012
Medusae (Cnidaria: Hydrozoa) from a coastal upwelling zone, Culebra Bay, Pacific, Costa Rica. The hydromedusae have an important role in marine trophic webs due to their predatory feeding habits. This is the first study of this group of gelatinous marine
