An &lt;i&gt;r&lt;/i&gt;-strategist in Antarctic pack ice
Provedor de dados: 27
Autores: Bergmans, M.; Dahms, H.-U.; Schminke, H.K.
The Antarctic copepod &lt;i&gt;Drescheriella glacialis&lt;/i&gt;, an inhabitant of sea ice, is the first polar invertebrate metazoan to have been cultured throughout its life cycle. We describe its demographic characteristics on the basis of a laboratory cohort study and correlative field data. When compared to its closest temperate zone relatives, &lt;i&gt;D. glacialis&lt;/i&gt; shows temperate compensation of developmental and reproductive rates. A genuine &lt;i&gt;r&lt;/i&gt;-strategist in every respect, it does not fit established trends for Antarctic invertebrates but appears well adapted to the peculiar spatio-temporal variability.

Postembryonic development of &lt;i&gt;Tisbe gracilis&lt;/i&gt; (T. Scott) (Copepoda, Harpacticoida)
Provedor de dados: 27
Autores: Dahms, H.-U.; Bergmans, M.
All six naupliar and five copepodite stages of &lt;i&gt;Tisbe gracilis&lt;/i&gt; (T. Scott, 1985) are described. A key for the identification of the nauplius stages is given. The oral appendages of all copepodite stages are described. Sexual dimorphism is visible from the copepodite IV stage on.

Distribution and adaptations of sea ice inhabiting &lt;i&gt;Harpacticoida&lt;/i&gt; (Crustacea, Copepoda) of the Weddell Sea (Antarctica)
Provedor de dados: 27
Autores: Dahms, H.-U.; Bergmans, M.; Schminke, H.K.
Seven harpacticoid species were found to be associated with sea ice collected during 5 Antarctic cruises of the &lt;i&gt;RV Polarstern&lt;/i&gt;. Their distribution within the fast ice and pack ice zones of the Weddell Sea is presented. Whereas some individuals probably become entrapped into the ice only accidentally, at least 4 species are genuinely sympagic. These have evolved remarkable adaptations, as evidenced by field and laboratory studies of &lt;i&gt;Drescheriella glacialis&lt;/i&gt;, which is by far the most abundant. Such adaptations include: the ability to penetrate deep into ice; a comparatively high salinity tolerance allowing it to endure large salinity fluctuations associated with ice crystal formation and melting; good swimming ability,...

Sea ice inhabiting Harpacticoida (Crustacea, Copepoda) of the Weddell Sea (Antarctica)
Provedor de dados: 27
Autores: Dahms, H.-U.; Schminke, H.K.
Five species of harpacticoid copepods belonging to three families and four genera were collected from various samples of sea ice taken during five cruises of RV Polarstern to the Weddell Sea from 1985-89. One species is new and described, namely &lt;i&gt;Hastigerella antarctica&lt;/i&gt; sp. n. &lt;i&gt;Drescheriella racovitzai&lt;/i&gt; comb. n. (Griesbrecht, 1902), &lt;i&gt;Harpacticus furcifer&lt;/i&gt; Giesbrecht, 1902 and &lt;i&gt;Idomene antarctica&lt;/i&gt; (Giesbrecht, 1902) are redescribed. The fourth nauplius of an unknown representative of Ectinosomatidae is described as well as three naupliar stages of &lt;i&gt;Harpacticus furcifer&lt;/i&gt;.
