Global drivers of mangrove loss in protected areas

Conservation Biology, Volume 38, Issue 6, December 2024.
Abstract Despite increasing efforts and investment in mangrove conservation, mangrove cover continues to decline globally. The extent to which protected area (PA) management effectively prevents mangrove loss globally across differing management objectives and governance types is not well understood.

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

Molecular 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 ...

Evidence for a by‐product mutualism in a group hunter depends on prey movement state

Functional Ecology, Volume 38, Issue 10, Page 2123-2138, October 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Group‐hunting animals have been shown to engage their prey in long pursuits (kms) to increase capture success, but the evidence for this is limited to a few terrestrial species.

Monogeneos, parásitos de peces en México: estudio recapitulativo

Revista Mexicana de Ciencias Pecuarias, 2012
No obstante la importancia económica de la acuacultura, existen serias limitantes que frenan su crecimiento, destacando entre ellas las parasitosis, que en afecciones severas además de demeritar la calidad del producto, son capaces de anular la ...

El cambio climático global: impacto y adaptación de la acuacultura mexicana

Revista Mexicana de Ciencias Agrícolas, 2017
México es uno de los países del mundo más afectado por el Cambio Climático Global (CCG). El estado de Veracruz (localizado en la costa del golfo de México) es impactado por fuertes ciclones y tormentas tropicales cada año. Este estado es uno de los mayores productores de tilapia en el país.

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

Advanced 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 ...

Global mismatches between threat mapping research effort and the potential of threat abatement actions to reduce extinction risk

Conservation Biology, Volume 38, Issue 4, August 2024.
Abstract Threat mapping is a necessary tool for identifying and abating direct threats to species in the ongoing extinction crisis. There are known gaps in the threat mapping literature for particular threats and geographic locations, and it remains unclear if the distribution of research effort is appropriately targeted relative to conservation need ...

Size at sexual maturity, seasonal variation by maturity stages, and fecundity of the spotted round ray (Urobatis maculatus) and the thorny stingray (Urotrygon rogersi) from the northern tropical eastern Pacific

Journal of Fish Biology, Volume 104, Issue 5, Page 1587-1602, May 2024.
Abstract Round rays (family: Urotrygonidae) are commonly caught as by‐catch by shrimp trawl fisheries in the tropical eastern Pacific (TEP). However, little information on their life history and catch species composition exists for most round ray species, preventing the evaluation of the impact of fishing on their populations.
