Summary
A survey was made of the occurrence of zooplankton in fresh and brackish waters at Cape Thompson, Alaska between June 28, 1960 and August 7, 1961.
Fourteen species of Cladocera and 38 species of Copepoda (13 Calanoida, 11 Cyclopoida and 14 Harpacticoida) were distinguished in collections from 10 lakes, 8 lagoons, and 111 pools.
Males of Daphnia middendorffiana are illustrated and their geographical significance discussed.
Cyclops scutifer had the only hibernal developmental cycle; all others had developmental cycles during early summer or throughout the summer and fall.
Relatively complete seasonal developmental cycles are presented for Holopedium gibberum, Daphnia middendorf iana, Heterocope septentrionalis, Eurytemora canadensis, E. gracilicauda, Limnocalanus johanseni, Diaptomus pribilofensis, D. arcticus, Cyclops scutifer, and C. magnus.
Zusammenfassung
Eine Übersicht des Vorkommens vom Zooplankton in der Zeit zwischen dem 28. juni, 1960 and dem 7. August 1961 im Süsswasser und im Brackwasser des Kaps Thompson, Alaska wird hier gegeben.
Von den Sammlungen aus 10 Seen, 8 Lagunen and 111 Teichen sind 14 Spezies der Cladoceren and 38 Spezies der Copepoden (darunter 13 der Calanoiden, 11 der Cyclopoiden, und 14 der Harpacticoiden) unterschieden worden.
Die männlichen der Daphnia middendorfliana werden hierin illustriert und die geographische Bedeutung erläutert.
Cyclops scutifer hatte den einzigen winterlichen Entwicklungszyklus; die anderen hatten Entwicklungszyklen früh in dem Frühling oder während des ganzen Sommers and Herbstes.
Jahreszeitliche Entwicklungszyklen, die verhältnismässig vollkommen sind, werden für die folgenden vorgeführt: Holopedium gibberum, Daphnia middendorffiana, Heterocope septentrionalis, Eurytemora canadensis, E. gracilicauda, Limnocalanus johanseni, Diaptomus pribilofensis, D. arcticus, Cyclops scutifer, und C. magnus.
