Spatial and temporal patterns of macroinvertebrates in drift and on substrate of a mountain stream (Cordoba, Central Argentina)

Acta Limnologica Brasiliensia, 2013
AIMS: The aims of this study are to evaluate the effects of spatial and temporal variability of the macroinvertebrate fauna in drift and in the substrate of a mountain stream.

Altered Coral‐Turf Algae Competition Leads to the Passive Dissolution of Coral Skeletons Under Ocean Acidification

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
Under ocean acidification, turf algae are favored over corals, shifting the competition outcome and decreasing coral survival. The local pH microenvironment under the turf, resulting from associated biological activity, drives the dissolution of the coral carbonate skeleton.

The food niche overlap of five fish species in the Úpoř brook (Central Bohemia)

Knowledge and Management of Aquatic Ecosystems, 2013
The diet and food niche overlap of five fish species in the Úpoř brook was evaluated. The supply of food represented by benthos was studied, and the proportion of total food particles in the intestine of brown trout Salmo trutta L ...

From temporal variability to integrated metabolic balance: Interpreting total alkalinity and dissolved inorganic carbon relationships in dynamic coral reef ecosystems

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Linear regressions between total alkalinity (TA) and dissolved inorganic carbon (DIC) are widely used to infer the balance between net ecosystem calcification (NEC) and net ecosystem production (NEP) in coral reefs. Using high‐frequency carbonate chemistry observations from an Australian reef flat and simple numerical models, we show that TA ...

How are coastal benthos fed?

Limnology and Oceanography Letters, 2017
Water movement can influence the distribution of benthos, in part, by increasing food delivery; however, the impact of advective transport and turbulent diffusion on organic matter flux to nearshore benthic communities is not well quantified.

Amino Acids in the Natural Food Web of Global Fishponds: Way Forward for Precision Protein Feeding in Pond Cyprinid Aquaculture

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
ABSTRACT Natural food webs in freshwater pond ecosystems provide an important nutritional foundation for cyprinid aquaculture, yet information on their protein and amino acid composition remains fragmented. This review synthesized published data from 30 studies (1950–2026) reporting protein and indispensable amino acid (IAA) composition of freshwater ...

Landscape composition as a determinant of diversity and functional feeding groups of aquatic macroinvertebrates in southern rivers of the Araucanía, Chile

Latin American Journal of Aquatic Research, 2015
Changes in land use which directly or indirectly affect freshwater fauna constitute one of the principal anthropic factors which have caused world biological diversity to disappear rapidly during recent decades.

BRIGHT LIFE IN THE BENTHOS [PDF]

Journal of Experimental Biology, 2012
![Figure][1] Sinking through the inky ocean, it would seem that there is little light at depth: but you'd be wrong. ‘In the mesopelagic realm [200–1000 m] bioluminescence [light produced by animals] is very common’, says Sonke Johnsen from Duke University, USA, explaining that ...

Large wood supports hydrologically variable floodplain environments and aquatic biodiversity

Ecosphere, Volume 17, Issue 8, August 2026.
Abstract Riparian vegetation and wood play crucial roles in enhancing spatial heterogeneity in rivers. Historical removal of large wood and cutting of streamside forests around the world have simplified rivers and substantially reduced aquatic habitat complexity.
