Urban Pollution Promotes Biotic Simplification of the Zooplankton Community in Ponds in Northeastern Brazil

open access: yesFreshwater Biology, Volume 70, Issue 6, June 2025.
ABSTRACT Pollution significantly impacts aquatic biodiversity by limiting the species pool. However, considerable uncertainty remains regarding which community attributes should be used to demonstrate the effects of this anthropogenic disturbance. We propose that zooplankton taxonomic biodiversity could serve as a reliable pollution indicator in lentic

Lipid biomarkers reveal trophic relationships and energetic trade‐offs in contrasting phenotypes of the cold‐water coral Desmophyllum dianthus in Comau Fjord, Chile

open access: yesFunctional Ecology, Volume 38, Issue 1, Page 126-142, January 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Benthic suspension feeders like corals and sponges are important bioengineers in many marine habitats, from the shallow tropics to the depth of polar oceans. While they are generally considered opportunistic, little is known about their actual in situ diet.

Variaciones de abundancia y biomasa del zooplancton en un embalse tropical oligo-mesotrófico del norte de Venezuela

open access: yesRevista de Biología Tropical, 2010
La abundancia del zooplancton en los embalses está determinada principalmente por la velocidad y el contenido del agua, pero se sabe relativamente poco sobre los embalses tropicales.

Producción primaria fitoplanctónica de un lago somero turbio orgánico en relación con el zooplancton (La Pampa, Argentina)

open access: yesBiología Acuática, 2019
La producción primaria (PPr) es la energía fijada por los organismos autótrofos. En los ecosistemas acuáticos, se produce principalmente mediante procesos fotosintéticos realizados por algas planctónicas o bentónicas y macrófitas.

Zooplankton richness, abundance and biomass of two hypertrophic shallow lakes with different salinity [PDF]

open access: yes, 2012
The zooplankton of lakes is controlled by biological and physico-chemical parameters. Among the former, predation by fish can determine the replacement of large-sized species by small-sized ones and among the latter, salinity exerts negative effects on ...
