Molecular characterization of the tadpole shrimp Triops (Branchiopoda: Notostraca) from the Baja California Peninsula, México: New insights on species diversity and phylogeny of the genus
TLDR
Molecular and phylogenetic analyses indicate that the nominal Triops species T. longicaudatus is a mixture of several species such that, of the seven Triops American populations studied, six phylogenetic species can be identified and two morphologically and reproductively highly divergent forms can be grouped into a single monophyletic clade.
FRESHWATER SHRIMP OF THE GENUS MACROBRACHIUM (DECAPODA: PALAEMONIDAE) FROM THE BAJA CALIFORNIA PENINSULA, MÉXICO
TLDR
A taxonomic study of freshwater shrimp, which included an extensive field survey at 81 sites distributed on both the Pacific and the Gulf of California slopes and a revision of material from the area that had been deposited in scientific collections is made.
Are Prorocentrum hoffmannianum and Prorocentrum belizeanum (DINOPHYCEAE, PROROCENTRALES), the same species? An integration of morphological and molecular data
TLDR
Subtle morphological overlaps found in cell shape, size, and ornamentation lead us to conclude that P. hoffmannianum and P. belizeanum were a highly supported monophyletic clade separated into three subclades, which broadly corresponded to the sample collection regions.
First record of the family Thamnocephalidae (Crustacea: Anostraca) from Southeast Asia and description of a new species of Branchinella
TLDR
During a two-year investigation of freshwater microcrustaceans in Thailand, an undescribed species of fairy shrimp of the genus Branchinella Sayce, 1903 in the family Thamnocephalidae was discovered, which appears to be morphologically intermediate between B. kugenumaensis from Japan and east China and B. madurai Raj from India and Pakistan.
Effect of zooplankton type and abundance on prey consumption by the fairy shrimp, Streptocephalus proboscideus (Anostraca: Crustacea)
TLDR
This study confirms S. proboscideus as a non-selective filter feeder and suggests it may contribute to structuring its prey communities, because good escapers will be enriched in the medium, while poor escaper will be depleted.
STREPTOCEPHALUS SIRINDHORNAE, NEW SPECIES OF FRESHWATER FAIRY SHRIMP (ANOSTRACA) FROM THAILAND
TLDR
Streptocephalus sirindhornae, new species, the first freshwater anostracan from Thailand, is widespread in the northeast of the country, and sequence analysis of its SSU rDNA gene reveals that its closest relative is in fact the Indian species-pair S. dichotomus-S.
High intraspecific genetic divergence in the versatile fairy shrimp Branchinecta lindahli with a comment on cryptic species in the genus Branchinecta (Crustacea: Anostraca)
TLDR
It is argued that the amount of intraspecific divergence observed in B. lindahli is not consistent with the presence of cryptic species and that caution should be taken when attempting to delimit cryptic species within this group.
FATTY ACID COMPOSITION OF ARTEMIA (BRANCHIOPODA: ANOSTRACA) CYSTS FROM TROPICAL SALTERNS OF SOUTHERN MÉXICO AND CUBA
TLDR
Based on the fatty acid composition, the Artemia strains studied can be assessed as “freshwater” type, except for the one from Oaxaca that had a “marine’ type profile characterized by 3% to 4% of the fatty Acid C20:5 n3 (eicosapentaenoic).
Influence of light, DMSO and glycerol on the hatchability of Thamnocephalus platyurus Packard cysts
TLDR
Effects of two light intensities and different concentration of dimethyl sulfoxide (DMSO) and glycerol on hydrated cyst hatching inThamnocephalus platyurus were studied and apolar compounds like Ca2+ ionophore can be dissolved in DMSO to study the role of Calcium in cySt hatching.
