Evolution of Egg Size Strategies in Fairy Shrimps

The Southwestern Naturalist, 1977
Differences exist among fairy shrimps in the size of the eggs they develop. Large eggs that hatch into big larvae probably evolved in the relatively predictable melt-pond environment as a result of selection against small size by invertebrate predators.

eDNA metabarcoding bioassessment of endangered fairy shrimp (Branchinecta spp.)

Conservation Genetics Resources, 2020
Habitat degradation and land-use change severely threaten the survival of fairy shrimp and the vernal pools in which they live. Limiting effective fairy shrimp conservation management efforts is the ability to readily identify species without the capture and sacrifice of individuals for microscopy.

Mating Behavior in the Streptocephalus Fairy Shrimps (Crustacea: Anostraca)

The Southwestern Naturalist, 1981
Mating behavior in the Streptocephalus fairy shrimps consists of the following behavior patterns: detection and orientation, station taking, clasping, intromission, and disengagement. Since males have low parental investment in their offspring and since males must compete for receptive females, sexual selection should favor males which mate with ...

Acceptability of Fairy Shrimp (Streptocephalus seali) as a Diet for Larval Fish

The Progressive Fish-Culturist, 1987
Abstract Fairy shrimp (Streptocephalus seali), brine shrimp (Artemia salina), and a pelleted food were fed to tiger muskellunge (the hybrid of muskellunge, Esox masquinongy, and northern pike, E. lucius) to compare acceptability and nutritional value of the diets.

Hybridization and the Detection of Hybrids in the Fairy Shrimp Genus Streptocephalus

American Midland Naturalist, 1979
Viable adult hybrids were obtained in laboratory mating tests involving five species pairs of Streptocephalus fairy shrimps. Three hybrid types were distinguished from parental types using prominent diagnostic features of parental species: two hybrid types resembled only one parental species in diagnostic features. Laboratory hybrids provided a "search

Diversity and zoogeography of the fairy shrimps (Branchiopoda: Anostraca) on the Indian subcontinent

Hydrobiologia, 2017
The Indian subcontinent has a specific biogeographical history, but has remained understudied with respect to invertebrates like the Anostraca. In this study, we discuss the anostracan diversity and zoogeography on the subcontinent. We collected all pertinent literature and considered nineteen bioclimatic variables along with altitude and its ...

Feeding behaviour in the Antarctic fairy shrimp, Branchinecta gaini

Polar Biology, 2008
Direct observations of feeding behaviour in Branchinecta gaini are described. B. gaini possess sophisticated food manipulation behaviours, using their abdominal appendages to ‘scrape’ at and carry away food items. Scraping behaviour was employed by animals for both detrital feeding and the cannibalisation of dead conspecifics.

The Life Hitory of the Spiny‐Tailed Fairy Shrimp in Louisiana

Ecology, 1955
The "spiny-tailed fairy shrimp," as Creaser (1930) referred to Streptocephalus seali Ryder, has been recorded from seventeen states in all sections of the United States, as well as from Canada and Mexico. Although it is probably the most widely distributed of all the North American fairy shrimps, it remains one of the least known.

XXXII.—On the Feeding Mechanism of the Fairy Shrimp, Chirocephalus diaphanus Prévost

Transactions of the Royal Society of Edinburgh, 1928
Chirocephalus diaphanus, the Fairy Shrimp, feeds on minute suspended particles and organisms that it separates from water currents produced by its limbs. According to Lundblad (1920, p. 41), in the closely similar form, Tanymastix stagnalis (L.), an orally directed current is produced along the mid-ventral line between the trunk limbs which actually ...

Some Ecological Relations of Fairy Shrimps in Alkaline Habitats of Nebraska

American Midland Naturalist, 1970
Ecological studies on the distribution of fairy shrimps have been made from 246 sites in the sandhills region of Nebraska. New records for Nebraska have been established for Artemia salina, Branchinecta campestris, B. lindahli, B. mackini and Cyzicus mexicanus.
