I was glad to have read it, but remained unconvinced I knew what was at its heart, beyond the captivating contents of the rockpools.more

In the end, I wasn't convinced this book hung together. All of this is interesting, and interestingly accounted for. He discusses the bitter and harsh social history of Argyllshire. He looks at the philosophical ideas of Heraclitus.

Then he looks more widely at tides, at waves, at geology. Nicolson fashions his own rock pools in Argyllshire in Scotland in order to study, minutely, the life that fetches up there, and his resulting studies of shrimps, crabs, sea anemones and their place in the scheme of things engaged and enthralled me, even though, as a non scientist I struggled a bit to understand every word. He discusses the bitter In many ways this is a fascinating book.

Anyone who chooses can look beyond their own reflection and find the marvellous there, waiting an inch beneath their nose.more The sea is not made of water is an invitation to the shoreline. But its story is as much human as natural history: how far should our own lives be understood as an aspect of ecology? Do our buried beliefs about the tidal sea reflect a fundamental understanding of our relationship to nature? And is it the shifting condition of that tidal world, its pervasive uncertainty, its fierce interfolding of opportunity and threat, that makes it one of the most emblematic and revelatory habitats on earth? The intertidal has been the scene for all kinds of scientific discovery – from the workings of evolution to the intricacies of biological networks. The physics of the seas, the biology of anemone and limpet, the long history of the earth itself, the governing myths and stories of those who have lived and survived here: all interconnect in the zone where philosopher, scientist and poet can meet and puzzle over the nature of what exists. How do sandhoppers inherit an inbuilt compass from their parents? What is it that prawns know? How do crabs understand the tides? How can the death of one winkle guarantee the lives of its companions?Ĭonnections animate the book. In the sea is not made of water Adam Nicolson explores the multiple, interleaved layers of that world and the long human relationship with the shore.

How can the d Few places are as familiar as the shore – and few as full of mystery and surprise. Un courant descendant associé à un niveau particulièrement bas stimule l'activité de nage des crevettes, et il en résulte une concentration dans les parties profondes de leur habitat.Few places are as familiar as the shore – and few as full of mystery and surprise. Les résultats de ces observations ont montré que ces migrations sont déterminées à la fois par la vitesse du courant et par le niveau de l'eau. Par la suite, des crevettes marquées à l'aide d'un colorant bleu ont été libérées dans la partie supérieure d'une crique, à marée descendante et à marée montante, et suivies dans leurs migrations. varians sont dues à l'interaction des courants de marée et des rythmes d'activité diurnes des crevettes. Des captures régulières, à l'aide de verveux, ont d'abord été effectuées dans la partie supérieure d'une crique découverte par la marée et dans une mare saumâtre de dune, et laissent supposer que les migrations journalières de P. La migration journalière, liée aux marées, a été étudiée chez Palaemonetes varians, au cours de quelques campagnes d'été, en raison de la concentration frappante des individus de cette espèce dans les eaux profondes et calmes de son habitat intertidal.
