Unveiling coralline diversity of mesophotic rhodoliths in subtropical Japan, including new species of Sporolithon, emended genera Orientalilithon and Roseolithon (Corallinophycidae, Rhodophyta). [PDF]

J Phycol
Abstract The mesophotic zone off Tanegashima Island (approximately 30–40 m deep) is a marine macroalgal hotspot in subtropical Japan; however, the taxonomic diversity of calcifying red algal community remains poorly understood. Our phylogenetic analyses based on psbA, rbcL, and COI‐5P gene markers disclosed the presence of at least 12 rhodolith‐forming

Joint effects of elevated copper and temperature in juvenile Tambaqui exposed in black and white waters of the Amazon. [PDF]

J Fish Biol
Abstract This study aimed to investigate how exposure to elevated water temperature and metal concentration jointly affect the physiology of Amazonian fish. Aboard a research vessel in the Amazon, we evaluated the effects of water temperature (river T°C at 31.5°C and a + 4°C increase to 35.5°C) and of 3‐h copper (Cu) exposure (up to 600 μg/L) in ...

An updated classification of growth forms in non-geniculate coralline algae (Corallinophycidae, Rhodophyta). [PDF]

J Phycol
Abstract The current challenge of defining growth forms in the non‐geniculate coralline red algae was addressed. Since the 19th century, those who have worked on this large and globally distributed group of algae have tried to summarize and systematically describe their growth forms. This effort resulted in a plethora of terms, which could sometimes be

Magniporophytum gen. nov. and Orientalilithon gen. nov. (Hapalidiales, Corallinophycidae): Two new genera of coralline red algae from the Pacific Ocean, including the description of three new species. [PDF]

J Phycol
Abstract We propose, based on a robust set of molecular and morpho‐anatomical data of specimens from warm‐temperate Japan, two new genera of non‐geniculate coralline algae accommodating both attached and rhodolith‐forming species: Magniporophytum gen. nov. containing M. variabile sp. nov. (the generitype) and M. epizoicum sp. nov.

Mesures de houles partiellement stationnaires en zones côtière et littorale [PDF]

Mécanique & Industries, 2006
Les instruments de mesures des courants en mer permettent d'obtenir un nombre d'informations de plus en plus important grâce a des techniques de mesures de plus en plus sophistiquees. En particulier, les mesures ponctuelles de vitesses et de pression permettent d'obtenir des informations sur l'energie de la houle et sa direction de propagation.

Influence of the river flow on the structure of fish assemblage along the longitudinal gradient from river to reservoir

Zoologia (Curitiba), 2010
Changes in fish assemblage structure along a longitudinal gradient of the Paraíba do Sul River and Funil reservoir were studied to detect distribution patterns and the seasonal influence of the inflowing river.

COMPOSITION DU PEUPLEMENT PISCICOLE D'UN PETIT ESTUAIRE ANTHROPISÉ (LE COUESNON, FRANCE).

Knowledge and Management of Aquatic Ecosystems, 2001
Dans un petit estuaire du nord de la Bretagne (France), l'ichtyofaune a été échantillonnée lors de chaque saison d'une année sur six stations selon une répartition amont-aval. 28 espèces ont ainsi été capturées à l'aide de deux engins de pêche, une senne

Construction des trajectoires paysagères de zones humides littorales

, 2021
Les espaces littoraux sont l’objet de nombreux enjeux. Avec le changement climatique, les collectivités se doivent d’entreprendre des approches prospectives du développement territorial. Celles-ci doivent se nourrir de l’étude des territoires, de leurs trajectoires et des temporalités de changements.

Fish Assemblages in an Urbanized Neotropical Basin: Influence of Environmental Factors Across Dry and Rainy Periods

International Review of Hydrobiology, Volume 111, Issue 2, December 2026.
ABSTRACT This study investigated the effects of season and environmental disturbances on fish communities in neotropical rivers of the Sorocaba basin, a Sub‐Basin of the Paraná River in Southeast Brazil, based on sampling 1196 individuals from 49 species, including two non‐native and one threatened with extinction.
