Behavior of Marine Animals: Current Perspectives in Research
ISBN: 9781468429879 / Angielski / Miękka / 458 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Four years ago we began soliciting articles for this volume from authors who were engaged in comprehensive research on whales. From the outset we decided not to limit the subject matter to behavior but to also include natural history. Much of what is known about the behavior of whales arose from studies whose principal aim was not behavior, much as it did for other animal groups before behavior was considered a distinct discipline. Thus in many of the articles behavior is closely intertwined with natural history and in others is completely overshadowed by a basic natural history approach. Our...

Diel Vertical Migration of Zooplankton in Lakes and Oceans: Causal Explanations and Adaptive Significances
ISBN: 9789400790810 / Angielski / Miękka / 356 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Whatever theory may be advanced to explain diurnal migration, the underlying reactions involved must be demonstrated conc- sively in the laboratory before the explanation can be ?nally accepted George L. Clarke 1933 p. 434 In oceans and lakes, zooplankton often make diel vertical migrations (DVM), descending at dawn and coming up again in late afternoon and evening. The small animals cover distances of 10-40 m in lakes or even a few hundred metres in the open oceans. Although not as spectacular as migrations of birds or the massive movements of large mammals over the African savannas, the...

Rotifera XII: New Aspects in Rotifer Evolution, Genetics, Reproduction, Ecology and Biogeography
ISBN: 9789400735354 / Angielski / Miękka / 209 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Rotifera are a very common group of invertebrates and, therefore, play a considerable role in the food webs of plankton and benthos of lakes and rivers worldwide. Their ecological success is based on their distinct pattern of reproduction: a large part of them, the Monogononta, are famous for their unique mode of reproduction with parthenogenetic females and a rather rare appearance of sexuality with males. On the other hand, the Bdelloidea completely abstain from sexuality. Although many life cycle characteristics make the Rotifera ideal objects for the study of important scientific and...
