Microchemical provenancing of prey remains in cormorant pellets reveals the use of diverse foraging grounds. [PDF]
J Wildl Manage, 2022 Microchemical provenancing was successfully applied to otoliths exposed to digestion by piscivorous birds and it was possible to clarify on a small scale from which waterbodies or habitat clusters the birds obtain their food. By the use of prey provenancing, site‐specific management plans can be developed and the effect of management measures on ...

Latin American Journal of Aquatic Research, 2023 The southern rays bream (Brama australis) is a highly migratory, epi-mesopelagic species supporting an important artisanal fishery off central-southern Chile. Despite its importance, several questions exist about this species's demography and migratory routes. The first step in understanding the migratory behavior of B.

Freshwater Biology, Volume 68, Issue 2, Page 312-324, February 2023., 2023 Abstract Charophytes are a key group of submerged macrophytes in temperate hardwater lakes, but have declined or been replaced by angiosperms as a result of eutrophication for more than 100 years. At present, this process is continuing in many European lakes despite an overall reduced nutrient loading.

Limnology and Oceanography: Methods, Volume 20, Issue 12, Page 789-810, December 2022., 2022 Abstract Mid‐trophic level (MTL) organisms play a key role in the sub‐Antarctic ecosystem food web, linking primary producers and tertiary consumers transferring energy across trophic levels. In this region, the relative abundance of MTLs has been monitored using single‐frequency acoustic data collected opportunistically in a time series of trawl ...

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 31, Issue 4, Page 948-963, April 2021., 2021 Abstract Invaders affect native species across multiple trophic levels, influencing the structure and stability of freshwater communities. Based on the ‘trophic position hypothesis’, invaders at the top of the food web are more harmful to native species via direct and indirect effects than trophically analogous native predators are. However, introduced

Avances en el estudio reproductivo de la reineta (Brama australis) en la costa central de Chile [PDF]
Latin American Journal of Aquatic Research, 2017 RESUMEN La información sobre los rasgos reproductivos de Brama australis, es escasa o no ha sido actualizada. Mediante análisis histológico, se estudió el tipo de reproducción, la madurez en longitud y las diferentes fases de desarrollo gonadal de machos y hembras. Se analizaron ejemplares capturados en la zona costera de Chile central.

Brama australis gel obtention and rheological characterization
Procedia Food Science, 2011 AbstractGelatine from marine sources has been looked upon as a possible alternative to bovine and porcine gelatine. Common problems connected with fish gelatine from cold water species, such as those from Chilean coast, are low gelling and melting temperature and low gel modulus.
