Exploring ecohydrology through the lens of local fishers in the Bolivian Amazon

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract The natural flow regimes of Andean‐Amazon tributaries play a vital role in sustaining their rich biodiversity and productive local fisheries, but ongoing and proposed alteration of river flow regimes by large dams threatens to negatively impact river ecosystems. Despite its importance, our understanding of how hydrologic variability influences

Assessing fish assemblages similarity above and below a dam in a Neotropical reservoir with partial blockage

Brazilian Journal of Biology
Damming rivers disrupts the water flow and changes the ichthyofauna organisation. We investigated an impoundment with permanent connection and homogeneous environmental conditions between the zones above and below the dam.

DRELIO : Un drone hélicoptère pour le suivi des zones littorales

XIèmes Journées, Les Sables d'Olonne, 2010
La connaissance du littoral, sa protection, son amenagement necessitent un suivi des changements qui s'y produisent. Toutefois, en France, devant l'etendue des facades maritimes a couvrir, les techniques de mesures in situ ne peuvent etre appliquees de facon systematique.

A new South American darter (Crenuchidae: Characidium) from rivers draining the Northeastern Mata Atlantica Freshwater Ecoregion, Brazil: morphological and molecular evidence

Journal of Fish Biology, Volume 108, Issue 4, Page 1311-1323, April 2026.
Abstract Characidium tupi, a new species from rivers draining the southern portion of the Northeastern Mata Atlantica Freshwater Ecoregion, is described. The new species can be distinguished from all congeners by its colour pattern, including 7–14 dark bars enlarged and more conspicuous on their ventralmost portion, resulting in a longitudinal series ...

Le processus de production du risque « submersion marine » en zone littorale : l’exemple des territoires « Xynthia » [PDF]

Norois, 2012
Les lourdes conséquences des catastrophes naturelles restent (trop) souvent expliquées, à travers les médias notamment, par les phénomènes de changements climatiques, par la défaillance des systèmes de défense ou par le caractère exceptionnel des conditions naturelles comme ce fut le cas lors des événements de février 2010 « Xynthia ».

Atténuer l’impact du marnage artificiel sur la biodiversité des retenues : l’exemple du projet UROS et de ses îlots flottants

Sciences, Eaux & Territoires
De nombreux plans d’eau voient leurs zones littorales, naturellement très biogènes, dégradées par le marnage artificiel. L'utilisation d'îlots flottants offrant en permanence des habitats diversifiés apparaît comme une solution potentielle d’atténuation

Dismantling the genus Tarenna (Rubiaceae: Pavetteae) in Africa and Madagascar, with the description of three new genera

TAXON, Volume 75, Issue 1, February 2026.
Abstract As presently circumscribed, the Paleotropical genus Tarenna, belonging to the tribe Pavetteae (Rubiaceae), comprises about 200 species and has its centres of diversity in tropical Asia and Africa. Previous molecular phylogenetic studies of the tribe revealed the polyphyly of Tarenna, suggesting that the genus needs to be recircumscribed ...

Metabolic strategy and appetite regulation of Japanese eel (Anguilla japonica) subjected to long‐term food deprivation: Physiological adaptation and survival implication

Journal of the World Aquaculture Society, Volume 57, Issue 1, February 2026.
Abstract This study examined the effects of different food deprivation periods (0, 7, 14, 28, 42, and 84 days) on physical indexes, appetite gene expression, physiological and biochemical levels and intestinal histology in Japanese eel (Anguilla japonica).

Gouverner des écosystèmes en tension: Conflictualités et dynamiques d'acteurs dans les mangroves de Douala (Cameroun)

Canadian Geographies / Géographies canadiennes, Volume 70, Issue 1, Spring / printemps 2026.
Résumé Dans un contexte régional alimenté par la multiplication des tensions autour de l'accès, de l'usage et du contrôle des ressources naturelles, les mangroves de Douala se révèlent être un terrain emblématique pour apprécier la conflictualité socio‐environnementale à l'échelle urbaine.

The Agricultural Heritage System framework for collaborative environmental governance: A case for the Bay of Fundy's dykelands and foreshore marshes

Canadian Geographies / Géographies canadiennes, Volume 70, Issue 1, Spring / printemps 2026.
Abstract Canadian production systems face conflict between conservation and production goals, especially amid the impacts of climate change. The problem may, in part, be the frameworks we use to understand them. One potential framework that merits further research in this context is the Agricultural Heritage System.
