The distribution, abundance, and ecology of larval tunas from the entrance to the Gulf of California [PDF]

open access: yes, 1970
ENGLISH: This study is based on collections of larvae of Thunnus albacares, Euthynnus llneatus, and Auxis sp. obtained from surface and oblique net tows made during seven cruises, each along a comparable track in the entrance of the Gulf of California ...

Scaling the effects of size and temperature on animal consumption rates from individuals to populations in a subtropical reef fish

open access: yesFunctional Ecology, Volume 39, Issue 12, Page 3385-3395, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Measuring how temperature and body size drive individual consumption rates is fundamental to predict how climate change might shape population‐level consumption pressure. Yet, such measurements remain rare.

Validación de imágenes satelitales de temperatura superficial del mar mediante observaciones in situ

open access: yesBoletín Científico CIOH, 2003
La temperatura superficial del mar, medida in situ durante el crucero oceanográfico "Caribe-2003" a bordo del ARC "Malpelo" entre el mes de marzo y abril del 2003 en aguas de la Guajira, se compara con mediciones remotas de radiómetros de alta resolución producidas por los satélites NOAA-16-y NOAA-17. En un lapso de dos semanas, 252 mediciones en

Predictions of southern migration timing in coastal sharks under future ocean warming

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract Projected redistribution of marine species due to ocean warming may undermine current conservation efforts. Yet, there have been few studies on how ocean warming may alter migration timing. Across 5 years of acoustic telemetry data (2018–2022), we determined environmental drivers of southward migration timing for 6 migratory shark species from

Three-months extended and seasonal forecast of sea surface temperature anomalies for thermodynamic climate prediction

open access: yesGeofísica Internacional, 2000
La ecuación de conservación de energía térmica aplicada a la capa de mezcla oceánica se utiliza para la predicción de las anomalías de la temperatura de la superficie del mar y de sus cambios mensuales para periodos extendidos de tres meses, así como ...

Muscle glycogen and blood lactate in yellowfin tuna, Thunnus albacares, and skipjack, Katsuwonus pelamis, following capture and tagging [PDF]

open access: yes, 1964
ENGLISH: Tagging and the recovery of tagged yellowfin (Thunnus albacares) and skipjack (Katsuwonus pelamis) tunas are important aspects of the investigations conducted by the Inter-American Tropical Tuna Commission in the Eastern Tropical Pacific Ocean.

Morphological types and seasonal variation in eggs of zooplankton species from bottom sediments in Bahia Blanca Estuary, Argentina [PDF]

open access: yes, 2006
Resting egg production is a survival mechanism in zooplankton species against adverse environmental conditions. Egg accumulation in the upper layer of the bottom sediments is fundamental to the resurgence of the populations of these species when ...

Impact of temperature and hypoxia on the size and survival of aquatic insects

open access: yesEcological Entomology, Volume 50, Issue 6, Page 1023-1032, December 2025.
Understanding size–temperature relations is crucial for the conservation of aquatic insects. We hypothesised that the combination of high temperature and hypoxia will lead to a reduction in the size of larvae and pupae of aquatic insects (non‐biting midge, Chrionomus riparius). We showed that Chironomus riparius pupae were significantly smaller at 30°C
