Morphological abnormalities in cladocerans related to eutrophication of a tropical reservoir

open access: yes, 2016
In zooplankton communities, morphological changes in Cladocera (Crustacea: Branchiopoda) may be resulting from water pollution by anthropogenic activities and/or natural events.

Predation by Larval Damselflies on Cladocerans

open access: yesJournal of Freshwater Ecology, 2010
ABSTRACT We quantified the strike and capture efficiency, handling time, and functional response of Enallagma hageni and Ishnura verticalis larvae feeding on several sizes of the cladocerans Polyphemus pediculus, Daphnia pulex, and Holopedium gibberum. Both species were most efficient at capturing and ingesting P.

Partners or passengers? Revisiting the association between diatoms and aquatic animals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Numerous studies have revealed the importance of research on the communities capable of colonizing animal surfaces (epibionts) and the animals on which they live (basibionts). Very few studies have considered epizoic diatoms, and there are gaps and biases in our knowledge, including the choice of basibionts, the methods used, and the habitats ...

Long-Term Responses of Crustacean Zooplankton to Hydrological Alterations in the Danube Inland Delta: Patterns of Biotic Homogenization and Differentiation

open access: yesDiversity
Our study addresses how large-scale hydrological alterations shape zooplankton biodiversity in floodplain ecosystems, which are highly sensitive to changes in river connectivity.

Microcrustacean assemblages composition and environmental variables in lakes and ponds of the Andean region - South of Chile (37-39° S) Composição de comunidades de microcustáceos e variáveis ambientais em lagos e lagoas da região andina - sul do Chile (37-39° S)

open access: yesBrazilian Journal of Biology, 2011
The zooplankton assemblages in Chilean Patagonian lakes are characterised mainly by their low biodiversity and high predominance of calanoids copepods, a pattern that has been studied for large and deep lakes between 38-51° S, and shallow ponds at 51° S.

From the sea to DNA barcode: Optimized preservation method for gelatinous zooplankton integrative taxonomy

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Assigning taxonomic identity and thus assessing taxonomic diversity in gelatinous zooplankton is challenging due to their fragility and difficult preservation. Formalin fixation compromises DNA integrity, while flash‐freezing, ethanol, and acetone preservation affect morphological features. In this study, we developed a methodological protocol

Warming modifies trophic impacts of invading shrimp with impact varying among primary producers

open access: yesOikos, EarlyView.
Environmental change drivers, such as climate change and species invasions, can disrupt biological networks and weaken ecosystem stability. Acting together, these drivers may interact and alter the effects on the ecosystem. However, few studies have examined the interactive effects of climate change and species invasions, particularly in aquatic ...

Crustacean communities in coastal ephemeral pools in the Araucanía region (38° S, Chile)

open access: yesBrazilian Journal of Biology
The fauna communities of ephemeral pools in southern Chile are characterized by heterogeneity of crustacean taxa; nevertheless, no detailed studies exist of their community structure.

Diurnal Changes of Zooplankton Community Reduction Rate at Lake Outlets and Related Environmental Factors. [PDF]

open access: yesPLoS ONE, 2016
The reduced zooplankton abundance at the outlet sections of lakes depends on the occurrence of preying fry. Therefore, light conditions can play a major role in the drift of zooplankton along river outlets.
