Employing invertebrates to restore herbivory on Caribbean coral reefs: recent developments and remaining barriers

open access: yesRestoration Ecology, Volume 33, Issue 4, May 2025.
With coral reefs in global decline and further threatened by growing anthropogenic impacts, effective strategies for restoring these critical ecosystems are increasingly sought after. In Caribbean reefs, where disease outbreaks and fishing pressure have reduced herbivore abundances and facilitated widespread phase shifts from coral to algal dominance ...

Evolution of the vaquita/totoaba socio‐ecological system in the Upper Gulf of California, Mexico

open access: yesEcosphere, Volume 16, Issue 2, February 2025.
Abstract The Upper Gulf of California (UGC) hosts a rich marine biodiversity. Complex climatic processes generate high biological productivity enabling the use of resources in a complex socio‐ecological processes (SEPs). Through a literature review, evolution and aggravation of the SEP over 50 years are analyzed.

Crossing the Pacific: Genomics Reveals the Presence of Japanese Sardine (Sardinops melanosticta) in the California Current Large Marine Ecosystem

open access: yesMolecular Ecology, Volume 33, Issue 22, November 2024.
ABSTRACT Recent increases in frequency and intensity of warm water anomalies and marine heatwaves have led to shifts in species ranges and assemblages. Genomic tools can be instrumental in detecting such shifts. In the early stages of a project assessing population genetic structure in Pacific Sardine (Sardinops sagax), we detected the presence of ...

The Multiphasic Teeth of Chiton Articulatus, an Abrasion‐Resistant and Self‐Sharpening Tool for Hard Algae Collection

open access: yesAdvanced Functional Materials, Volume 34, Issue 33, August 14, 2024.
Investigation of the ultrahard teeth of a mollusk find in the tropical Pacific reveals the presence of multiple phases of iron oxide as well as calcium phosphate, with highly tuned microstructural features. The combination of these features results in an abrasion‐resistant tough structure with a self‐sharpening ability, which contribute to developing ...
