In the songs and bubble feeding of humpback whales; in young killer whales learning to knock a seal from an ice floe in the same way their mother does; and in the use of sea sponges by the dolphins of Shark Bay, Australia, to protect their beaks while foraging for fish, we find clear examples of the transmission of information among cetaceans. Just as human cultures pass on languages and turns of phrase, tastes in food (and in how it is acquired), and modes of dress, could whales and dolphins have developed a culture of their very own? Unequivocally: yes. In The Cultural Lives of Whales and Dolphins, cetacean biologists Hal Whitehead, who has spent much of his life on the ocean trying to understand whales, and Luke Rendell, whose research focuses on the evolution of social learning, open an astounding porthole onto the fascinating culture beneath the waves. As Whitehead and Rendell show, cetacean culture and its transmission are shaped by a blend of adaptations, innate sociality, and the unique environment in which whales and dolphins live: a watery world in which a hundred-and-fifty-ton blue whale can move with utter grace, and where the vertical expanse is as vital, and almost as vast, as the horizontal. Drawing on their own research as well as a scientific literature as immense as the sea--including evolutionary biology, animal behavior, ecology, anthropology, psychology, and neuroscience--Whitehead and Rendell dive into realms both humbling and enlightening as they seek to define what cetacean culture is, why it exists, and what it means for the future of whales and dolphins. And, ultimately, what it means for our future, as well.

Etwa 60 km sudoestlich Wiens erstreckt sich oestlich des Neu siedler Sees das Gelande des "Seewinkels", das seinen Namen nach den zahlreichen groesseren und kleineren "Seen" fuhrt, die die meistens sehr flachen Mulden des Gelandes ausfullen, das nur wenige Meter uber dem Niveau des viel ausgedehntereD Neusiedler Sees liegt. Bezuglich der verschiedenen Theorien uber die Entstehung der Gewasser, ihrer morphologischen Charaktere sowie hinsichtlich der klimatischen Bedingungen, denen sie unterliegen, verweise ich auf H. FRANZ, K. HoeFLER und E. ScHERF (1937) und besonders auf H. LoeFFLER (1957), wo auch die neueste Literatur kritisch ausgewertet wird. Nur einige Eigentumlichkeiten der Gewasser seien hier kurz erwahnt, soweit sie fur das Verstandnis der nachfolgenden Ausfuhrungen grundlegend sind. Samtliche stehenden Gewasser haben nur eine sehr geringe Tiefe, die selten I m ubersteigt. Es fehlt also stets die durch eine groessere Tiefe bedingte Zonierung, durch die ein See ausgezeichnet ist, so dass es sich in allen Fallen - auch wenn der Volksmund von einem "See" spricht -um Gewasser mit teichartigem Charakter handelt, die, mundartlich verschieden, als Lacken oder Lachen bezeichnet werden. Sie liegen vorwiegend auf tonigen Alkaliflachen oder "Zickboeden" (nach dem ungarischen "szik" = Soda, Salz), weniger auf sandigem oder auch sumpfigem und ausgesusstem Boden.

Much of what you’ve heard about plastic pollution may be wrong. Instead of a great island of trash, the infamous Great Pacific Garbage Patch is made up of manmade debris spread over hundreds of miles of sea—more like a soup than a floating garbage dump. Recycling is more complicated than we were taught: less than nine percent of the plastic we create is reused, and the majority ends up in the ocean. And plastic pollution isn’t confined to the open ocean: it’s in much of the air we breathe and the food we eat. In Thicker Than Water: The Quest for Solutions to the Plastic Crisis, journalist Erica Cirino brings readers on a globe-hopping journey to meet the scientists and activists telling the real story of the plastic crisis. From the deck of a plastic-hunting sailboat with a disabled engine, to the labs doing cutting-edge research on microplastics and the chemicals we ingest, Cirino paints a full picture of how plastic pollution is threatening wildlife and human health. Thicker Than Water reveals that the plastic crisis is also a tale of environmental injustice, as poorer nations take in a larger share of the world’s trash, and manufacturing chemicals threaten predominantly Black and low-income communities. There is some hope on the horizon, with new laws banning single-use items and technological innovations to replace plastic in our lives. But Cirino shows that we can only fix the problem if we face its full scope and begin to repair our throwaway culture. Thicker Than Water is an eloquent call to reexamine the systems churning out waves of plastic waste.

1m Jahre 1915 hatte ich ein halb popnliires Werk, "Insektlivet i ferske Vande" ("Das Insektenleben im StiBwasser"), herausgegeben. In diesem Werke waren hauptsiichlich die Ergebnisse meiner eigenen Untersuchungen tiber Wasser insekten gesammelt, Ergebnisse, die damals schon fast aIle in einer Reihe von Arbeiten in ausliindischen Zeitschriften veroffentlicht waren; im tibrigen war das Buch auf der gesamten, den Gegenstand betreffenden Literatur aufgebaut. In der Zeit von 1900. bis 1915 sind ferner noch Arbeiten tiber verschiedene andere StiBwasserorganismen, in erster Linie tiber StiBwasserplanctonten, er schienen. Die Hauptpuplikation war "Planctoninvestigations of the Danish Lakes" 1904 bis 1908, zwei Quartbiinde mit zahlreichen Tafeln. Spiiter wurden zum Teil von Ausliindern, die in meinem Laboratorium als Assistenten gearbeitet hatten, zum Teil von anderen, aber auch von mir selbst eine Reihe monographi scher Untersuchungen tiber verschiedene Tiergruppen des StiBwassers, tiber Culiciden, Infusorien, Trematoden, Rotiferen, Nematoden, Cladoceren, Hydra chniden, ferner zusammenfassende Seeuntersuchungen (Furesee, Frederiksborger SchloBteich, Esromsee) publiziert, und zwar siimtlich in den "Kg . Danske Videnska bernes Selska bs Skrifter." Ein groBer Teil meiner Untersuchungen, so tiber Wasserspinnen und Schnek ken, ist aber nicht veroffentlicht worden. Das gleiche gilt von Beobachtungen tiber das Leben der StiBwasserorganismen, die ich auf meinen zahlreichen Ex kursionen machen konnte und die nur in meinen Notizen verzeichnet sind. Es war daher seit langem mein Wunsch, dieses umfangreiche und auch das nach 1915 publizierte Material in einem groBeren Handbuch tiber die gesamte wirbellose Fauna des StiBwassers zu sammeln, genau wie es seinerzeit mit meinen insektenbiologischen Untersuchungen in den "Wasserinsekten" geschehen ist."
