Total Numbers and Movements of Photo‐Identified Subantarctic (Type D) Killer Whales

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT The distinctive Subantarctic (Type D) killer whale (DKW) (Orcinus orca) is a highly divergent and apparently inbred form previously known only from three mass strandings and several dozen at‐sea sightings, primarily from Patagonian toothfish (Dissostichus eleginoides) longline vessels in the southern Indian Ocean and from tourism vessels in ...

Bioaccumulation d'un polychlorobiphényle commercial dans une chaîne trophodynamique expérimentale en eau douce

Knowledge and Management of Aquatic Ecosystems, 1978
Ce travail décrit les conditions d'expérimentation d'un polychlorobiphényle commercial sur les différents maillons d'une chaîne alimentaire en eau douce : algues-crustacés-poissons. Après avoir déterminé les modalités de contamination compatibles avec la

Subterranean environments contribute to three‐quarters of classified ecosystem services

Biological Reviews, Volume 101, Issue 3, Page 1582-1605, June 2026.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Higher Trophic Status Leads to More Diverse and Divergent Microeukaryote Communities Over Time in Urban Lakes From the Greater Paris (France)

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Microeukaryote dynamics across a eutrophication gradient in Greater Paris region lakes showed richness peaking at intermediate trophic levels and communities becoming more modular, variable, and less connected with higher trophic status compared to oligo‐to‐mesotrophic lakes.

Water quality and water-use conflicts in Lake Taabo (Ivory Coast) [PDF]

, 2012
The Lake Taabo (Ivory Coast, Africa) results of the construction of the Taabo dam on the Ban- dama River. The changes in the water level of the 69-km² lake depend on 1) the rainfall linked to alternating dry/wet seasons; 2) the extraction of water for ...

Genome‐Wide Population Structure of Lake Whitefish (Coregonus clupeaformis) in a Subarctic Great Lake

Evolutionary Applications, Volume 19, Issue 6, June 2026.
ABSTRACT Advances in genomics have facilitated the delineation of fisheries management units, which can be challenging in systems such as large lakes, in which high gene flow tends to limit genetic structure. In Great Slave Lake, Lake Whitefish populations have supported an important commercial fishery since the mid‐1940s. The genetic structure of Lake

The Aggregation of Fish in the Metalimnion Constrains Zooplankton Diel Vertical Migration

Freshwater Biology, Volume 71, Issue 6, June 2026.
ABSTRACT The role of fish predation in zooplankton diel vertical migration (DVM) is well established, where zooplankton move to deep waters during the day—to hide from visual predators in surface layers—and return to the epilimnion at night (i.e., ‘normal’ DVM), to feed on phytoplankton.

Marécages, une pollution par essence? Conditions d'une écopoétique des marais et autres zones humides au XXe siècle

Orbis Litterarum, Volume 81, Issue 3, Page 271-280, June 2026.
Abstract To expose the pollution of marshes and swamps, whether by hydrocarbons or other contaminants, the French or Francophone author of the twentieth century must first confront a literary tradition that equates stagnant water with a volatile poison and, more broadly, wetlands with toxic environments. In his article “Wetland Gloom and Wetland Glory,”
