Arctodiaptomus salinus inhabits water bodies across Eurasia and North Africa. Based on our own data and that from the literature, we analyzed the influences of several factors on the intra- and inter-population variability of this species. A strong negative linear correlation between temperature and average body size in the Crimean and African populations was found, in which the parameters might be influenced by salinity. Meanwhile, a significant negative correlation between female body size… Expand

Morphometric variability of Arctodiaptomus salinus (Copepoda) in the Mediterranean-Black Sea region.
Assessment of the intra- and inter-population morphometric variability of A. salinus in the Mediterranean-Black Sea region and discusses some observed regularities of linear body parameters and proportions found no effects of temperature, pH and salinity on the female/male parameter ratio, and there were significant differences in the body proportions of males and females in different populations.

Integral Indicators of Variability of Arctodiaptomus salinus (Daday, 1885) (Copepoda, Diaptomidae) and Their Possible Use in Assessing the Population State
The authors evaluate the effect of temperature, salinity, and population density; estimate the integral characteristics of the variability levels and connectivity of morphometric parameters; and discuss the possibility of using these integral characteristics for diagnostics of the planktonic-crustacean population status.

Does salinity affect body proportions and “size/mass” ratios of highly halotolerant Baeotendipes noctivagus larvae (Diptera, Chironomidae)?
Salinity is not the only factor affecting the size and mass of chironomid larvae, and it is inappropriate to use only one coefficient “b” for all chironOMid larvae. Expand
Zooplankton communities in Mediterranean temporary lakes: the case of saline lakes in Cyprus
Temporary saline lakes are diverse ecosystems mostly located in arid areas. In the Mediterranean region they are among the most remarkable, but also the most threatened habitats; thus, effectiveExpand
Environmental and zooplankton parameter changes during the drying of a saline shallow temporary lake in central Argentina
Central Argentina has numerous saline lakes sustained by groundwater sources and rainfall. These lakes are temporary and experience significant changes in water level and salinity, depending on wetExpand

How saline and hypersaline lakes may contribute to overcome this problem is discussed and a list of fish and shrimp species that can be cultivated in saline lakes is given that have excellent nutritional value. Expand

Body size and its variability in the copepod Acartia margalefi (Calanoida) from Lake Acquatina (SE Italy)
The results suggest that the body size of A margalefi (a. species adapted to variable environments) is inversely correlated with favourable conditions for reproduction, and it shows a different variability range in the two sexes probably due to the differe... Expand
The Influence of Salinity and Temperature on the Reproduction of Arctodiaptomus Salinus (Daday, 1885) (Copepoda, Calanoida) In The Temporary Salt Marsh, "La Sebkha Zima" (Morocco)
It appears that the sex ratio shows a dominance of females during the cold season and a dominate of males in the warm period, which results from a greater tolerance of the males with regard to environmental changes. Expand
Spatial and seasonal variations in size, body volume and body proportion (prosome:urosome ratio) of the copepod Acartia tonsa in a semi-closed ecosystem (Berre lagoon, western Mediterranean)
Biometric differences suggest that individuals must develop in situ for at least the final period of larval growth, despite the dispersion effect caused by hydrodynamic movements, and justify the use of somatic features (size and body proportion) to discriminate sets of individuals belonging to the same population. Expand
Post-embryonic developmental plasticity of Arctodiaptomus salinus (Copepoda: Calanoida) at different temperatures
Developmental instability could explain the high variability at high temperatures and the fluctuating speed of development throughout the successive stages and the interaction between mortality and developmental variability might be an important mechanism ensuring persistence of A. salinus populations in these fluctuating and stressing environments.

Study of salinity and temperature tolerance limits regarding four crustacean species in a temporary salt water swamp (Lake Zima, Morocco)
The tolerance range difference from species to species, together with the instability of the environmental conditions of the milieu, seem to be responsible for the quantitative and qualitative changes of the host fauna, which occur within the year and from year to year. Expand
Anostraca, Cladocera and Copepoda of Spanish saline lakes

Life histories of Neocalanus flemingeri and Neocalanus plumchrus (Calanoida: Copepoda) in the western subarctic Pacific
The life cycle of Neocalanus plumchrus was identical to the original description made for the Alaskan gyre population, although the recruitment to the surface layer during copepodite stages occurred 2 weeks to a month later than in other areas of the subarctic Pacific. Expand
Population Dynamics and Production of a Planktonic Marine Copepod,. Acartia clausii, in a Small Temperate Lagoon on San Juan Island, Washington
The population dynamics and production of Acartia clausii, a planktonic marine copepod, were studied during 1973 and 1974 in a small temperate lagoon to understand the factors which control the seasonal cycle of abundance. Expand
