CYCLOPOID COPEPODS

open access: yesJournal of the American Mosquito Control Association, 2007
Cyclopoid copepods have proved more effective for practical mosquito control than any other invertebrate predator of mosquito larvae. Their operational potential is enhanced by the fact that mass production is relatively easy and inexpensive. The exceptional potential of copepods for mosquito control was first realized about 25 years ago.

A model of chlorophyll a destruction by Calanus spp. and implications for the estimation of ingestion rates using the gut fluorescence method [PDF]

open access: yes, 1998
Chlorophyll a (chl a) destruction by groups of Calanus spp. with different long-term in situ feeding histories was compared. For copepods that had fed during both pre- and early-bloom conditions, degrees of chl a destruction were relatively constant at ...

Effect of supplying four copepod densities (Acartia sp. and Calanus pacificus) onthe productive response of Litopenaeus vannamei pregrown intensively at microcosm level

open access: yesCiencias Marinas, 2011
A seven-week experiment was performed to evaluate the effect of supplying copepods (Acartia sp. and Calanus pacificus), as exogenous feed during the intensive pre-growout phase of white shrimp (Litopenaeus vannamei), on the productive parameters and ...

Behavior out of control: experimental evolution of resistance to host manipulation [PDF]

open access: yes, 2019
Many parasites alter their host's phenotype in a manner that enhances their own fitness beyond the benefits they would gain from normal exploitation. Such host manipulation is rarely consistent with the host's best interests resulting in suboptimal and ...

Ectoparasitic copepod infestation on a wild population of Neotropical catfish Sciades herzbergii Bloch, 1794: Histological evidences of lesions on host

open access: yesInternational Journal for Parasitology: Parasites and Wildlife, 2017
We analyzed the infestation of the attached copepod species Lepeophtheirus sp on a wild population of Sciades herzbergii. The infestation and occurrence of attached copepods were related to body size, maturity and sex of host and the presence of lesions ...

A checklist of the marine Harpacticoida (Copepoda) of the Caribbean Sea [PDF]

open access: yes, 2006
Recent surveys on the benthic harpacticoids in the northwestern sector of the Caribbean have called attention to the lack of a list of species of this diverse group in this large tropical basin. A first checklist of the Caribbean harpacticoid copepods is

Biological responses to change in Antarctic sea ice habitats

open access: yesFrontiers in Ecology and Evolution, 2023
Sea ice is a key habitat in the high latitude Southern Ocean and is predicted to change in its extent, thickness and duration in coming decades. The sea-ice cover is instrumental in mediating ocean–atmosphere exchanges and provides an important substrate

Seasonal change in acclimatised respiration rate of Temora longicornis [PDF]

open access: yes, 2014
We investigated the seasonal changes in the respiration rate (R) of adult Temora longicornis (Müller) acclimatised to in situ conditions over 1 yr. Mean (±1 SE) R varied from 50.5 ± 2.8 nl O2 ind.-1 h-1 in December to 73.2 ± 3.53 nl O2 ind.-1 h-1 in ...

Copepods’ Response to Burgers’ Vortex: Deconstructing Interactions of Copepods with Turbulence [PDF]

open access: yesIntegrative and Comparative Biology, 2015
This study examined the behavioral response of two marine copepods, Acartia tonsa and Temora longicornis, to a Burgers' vortex intended to mimic the characteristics of a turbulent vortex that a copepod is likely to encounter in the coastal or near-surface zone.
