Fecundity, hatching rhythm, and the planktotrophic larval development of the hermit crab Pagurus comptus from sub-Antarctic waters of the Beagle Channel (Tierra del Fuego) were studied under controlled laboratory conditions of temperature, light cycle, food supply, and salinity. Fecundity was low, ranging from 134 to 848 eggs per female (cephalotoraxic shield length, SL, 2.3^5.0mm). Hatching ob...

The ability to identify chemical cues in the environment is essential to most animals. Apart from marine larval stages, anomuran land hermit crabs (Coenobita) have evolved different degrees of terrestriality, and thus represent an excellent opportunity to investigate adaptations of the olfactory system needed for a successful transition from aquatic to terrestrial life. Although superb processi...

The Ontology Web Language (OWL) has received considerable traction recently and is used in a number of industrial and practical applications. While decidable, all basic reasoning tasks for OWL are intractable (most of them are N2ExpTime-complete). Thus, in order to obtain a system capable of solving practically-relevant nontrivial problems, a number of theoretical and practical issues need to b...

the hermit crab fauna of the larak island was investigated, which revealed seven species representing five genera and two families. the family diogenidae represents six species namely areopaguristes perspicax (nobili, 1906), clibanarius signatus heller, 1861, dardanus lagopodes (forskål, 1775), d. tinctor (forskål, 1775), d. avarus heller, 1865, d. tirmiziae siddiqui & mclaughlin, 2003, while t...

Gastropods are known for the presence of calcareous shells, even after their death. The diversity this resource can be reflected in local living gastropods. These shells used by hermit crabs as protection and against desiccation. Coastal lagoons biodiversity hotspots site recruitment continent-sea connectivity, is sometimes altered connectivity events with adjacent areas. Therefore, we sought t...

Abstract Hermit crabs (Paguroidea; Latreille 1802) offer great opportunities to study animal behaviour and physiology. However, the animals’ size sex cannot be determined when they are inside their shell; information crucial many experimental designs. Here, we tested effects of two most common procedures used make leave shells: heating shell apex cracking with a bench press. We compared each on...

1922-1924 was a fruitful period of Maxim Gorky's literature work. It is related to searching new art form. The cycle “Stories 1922-1924” an expressive example “new prose”. For the first time, hermit character appeared in 1922-1924”. From point view generally recognized morality and Church, type ambiguous. characterized by both sinfulness holiness.
