Biologist Illuminates Glowing Underwater World

27 October 2014

National Geographic 2014 Emerging Explorer and marine biologist David Gruber studies animals that glow and shine underwater. Using special filters, he captures dazzling sights of marine creatures that use light—through bioluminescence or fluorescence—to interact in dark habitats.

New worm species discovery in the Netherlands


Cirriformia tentaculata in New Zealand

Translated from the Dutch marine biologists of Stichting ANEMOON:

Sunday, October 26, 2014

A new marine worm species, new for the Netherlands, has recently been discovered. Recreational divers found Cirriformia tentaculata in the central Oosterschelde estuary, and published their findings in ‘Het Zeepaardje’, the bimonthly magazine of the Strandwerkgemeenschap. It is not known whether the species has only just appeared on the Dutch coast, or that it had already been present for a long time but had never been discovered before because of its unobtrusive way of life.

Much sea life is hardly visible to the eyes of sport divers. At least 300 species of worms are known from our coastal waters. Many species live hidden in the sand and mud bottoms.

So, probably many worm species in the Netherlands have not been discovered yet.

Old and new natural history books


Alexander Reeuwijk, Naturalis, 19 October 2014

This photo shows author Alexander Reeuwijk behind a table with old natural history books in Naturalis museum in Leiden, the Netherlands. Like the other photos of this blog post, this is a cellphone photograph, of 19 October 2014.

On that day, as this blog already noted, Remco Daalder, Amsterdam city ecologist, was awarded the Jan Wolkers Prize. This prize is named after famous Dutch artist and author Jan Wolkers. Natural history was one of his subjects. The Jan Wolkers Prize is for the best natural history book of the year in the Netherlands. Remco Daalder’s book is about swifts.

Remco Daalder’s book had been nominated for the prize shortlist along with four other books. One of them was Alexander Reeuwijk’s book about nineteenth century British naturalist and evolution theorist Alfred Russel Wallace and his travels in Indonesia.

The three other nominations were for Mathijs Deen, for a book on the Wadden Sea region; Bibi Dumon Tak for her children’s book on common animals; and various authors for a book on Planken Wambuis nature reserve.

Back to Alexander Reeuwijk. He presented his ten favourite natural history books from the Naturalis collections. These books were from the sixteenth till the twentieth centuries.

Pierre Belon's book, Naturalis, 19 October 2014

The oldest of Alexander’s ten books was from 1553. It was by Pierre Belon from France, about fish. Belon is often seen as the first ichthyologist. In Belon‘s time, fishes were not differentiated from aquatic mammals, aquatic invertebrates, etc. The book discussed over a 100 species for the first time ever.

The copy in Leiden is of De aquatilibus; the Latin translation of the French original.

Pierre Belon's book on sharks, Naturalis, 19 October 2014

The book contains many woodcut pictures, including of hammerheads and other sharks.

Alexander Reeuwijk’s next book was from five years later, from 1558. It was by Conrad Gessner from Switzerland.

Lobster, in Gessner's book, Naturalis, 19 October 2014

Gessner’s Historiae animalium was the first attempt to describe all the animals known. Including the lobster pictured here on a woodcut in the book.

The original watercolour depiction of the lobster, used for the woodcut, is also present in Naturalis.

Mark Catesby, parrots, Naturalis, 19 October 2014

The next book was based on two books, originally in English. Mark Catesby died in 1749. He wrote Natural History of Carolina, Florida and the Bahama Islands, published 1729-1747. George Edwards wrote A Natural History of Uncommon Birds, published 1743-1764. Catesby’s and Edwards’ books contain many pictures of birds considered as ‘exotic’ by eighteenth century Europeans, like parrots in North America and the Caribbean.

Mark Catesby's and Edwards' Dutch translation, Naturalis, 19 October 2014

Catesby’s and Edwards’ books were translated into Dutch by M. Houttuyn, and published as Verzameling uitlandsche en zeldzaame vogelen in 1772-1781.

Spotted sandpiper, Naturalis, 19 October 2014

This picture in the Dutch translation depicts, below, a spotted sandpiper from the Americas.

Alexander’s fourth book was Nederlandsche Vogelen, about Dutch birds, by Nozeman and Sepp, published in various volumes 1770-1829.

Book number five was Histoire Naturelle des plus Rares Curiosoitez de la Mer des Indes. By Louis Renard, about marine life in Indonesia. The Leiden copy was published in 1782, after the author’s death.

Next, a book about plants in the Netherlands: the Flora Batava. Jan Kops wrote the first volume, published in 1800.

Then, Histoire naturelle générale des pigeons et des gallinacés (1808). Written by Coenraad Temminck; about pigeons. With pictures by Pauline de Courcelles Knip.

One of Ms de Courcelles Knip’s pictures for the book shows a Mauritius blue pigeon; now extinct.

The next book was about kingfishers. It was A monograph of the Alcedinidae: or, family of kingfishers, 1868-1871, by Richard Bowdler Sharpe. John Keulemans made the pictures.

Then, a book from the USA, by Sherman Foote Denton. It was As Nature Shows Them : Moths and Butterflies of the United States, East of the Rocky Mountains; from 1898.

Finally, another book on birds in the Netherlands: Ornithologia Neerlandica, de vogels van Nederland, 1922-1935. Eduard Daniel van Oort wrote it. Marinus Koekkoek painted the pictures.

Rare moth less rare in the Netherlands


This is a video from Japan about a Lithosia quadra caterpillar.

Translated from the Dutch Butterfly Foundation:

Thursday, October 23, 2014

The four-spotted footman is a moth with no permanent populations in the Netherlands. It is a rare migratory moth, entering the Netherlands from the south and possibly temporarily propagates. This year the moth is reported strikingly more than usually.

The four-spotted footman (Lithosia quadra) was from 2004 to 2013 reported only thirty times and thus a rare moth. In normal years, zero to four individuals were reported. In good years there were seven (2006) to nine (2012) four-spotted footmen. Only in 2014, over a hundred reports came in on Waarneming.nl and Telmee, from more than fifty different locations. The past week still saw a lot.
