Mariene flora en fauna te boek
Provedor de dados: 16
Autores: Hoeksema, B.W.; Gittenberger, A.
Het aantal boeken over de Nederlandse flora en fauna neemt gestaag toe. En ook de afgelopen jaren zijn er weer aardig wat nieuwe titels uitgekomen over het Nederlandse zeeleven. Op deze pagina's vier van die boeken. Eerder, in de Onderwatersport van april 2005, is ook al een aantal titels gepresenteerd van publicaties die mogelijk de moeite waard zijn om kennis te vergaren over de planten en dieren die  tijdens het duiken in Nederland de revue passeren.

The impact of small benthic passive suspension feeders in shallow marine ecosystems: the hydroids as an example
Provedor de dados: 16
Autores: Gili, J.-M.; Alvà, V.; Coma, R.; Orejas, C.; Pagès, F.; Ribes, M.; Zabala, M.; Arntz, W.; Bouillon, J.; Boero, F.; Hughes, R.G.
Benthic suspension feeders are abundant in littoral and shallow sub-littoral ecosystems, where they feed on the plankton and on organic matter suspended in the water column. Recent studies indicate that active suspension feeders with powerful water filtration mechanisms (e.g., bivalve molluscs) may exert an important influence on the abundance and production of phytoplankton, and probably zooplankton as well. Passive suspension feeders, such as hydrozoans, have received less attention, and their effect on shallow planktonic communities is poorly understood. This paper presents evidence that hydrozoans, which make only a minor contribution to benthic community biomass, capture large amounts of zooplankton and seston, and that they may play an important role...

High evolutionary potential of marine zooplankton
Provedor de dados: 16
Autores: Peijnenburg, K.T.C.A.; Goetze, E.
Open ocean zooplankton often have been viewed as slowly evolving species that have limited capacity to respond adaptively to changing ocean conditions. Hence, attention has focused on the ecological responses of zooplankton to current global change, including range shifts and changing phenology. Here, we argue that zooplankton also are well poised for evolutionary responses to global change. We present theoretical arguments that suggest plankton species may respond rapidly to selection on mildly beneficial mutations due to exceptionally large population size, and consider the circumstantial evidence that supports our inference that selection may be particularly important for these species. We also review all primary population genetic studies of open ocean...

Herinneringen aan een reis naar Sint-Helena
Provedor de dados: 16
Autores: Hartog, J.C. den.
Volgens gangbare inzichten zijn vrijwel alle oceanische eilanden uit zee opgerezen, wat impliceert dat ze oorspronkelijk kaal en zonder enig leven waren. Biologen zijn daarom bijzonder geïnteresseerd in het karakter en de herkomst van de huidige flora en fauna van die eilanden en in de kolonisatieprocessen. In het algemeen kan men stellen dat de kans op kolonisatie kleiner is naarmate een eiland verder van het vasteland (of van een ander eiland) verwijderd ligt. In feite is de zaak natuurlijk wel iets gecompliceerder, en spelen allerlei factoren een rol. Voor landorganismen zijn dit onder meer de klimatologische en meteorologische omstandigheden in het te overbruggen gebied, en de vestigingsmogelijkheden in de nieuwe omgeving. Kolonisatie door mariene...

Snellius II as a policy instrument for marine capacity building
Provedor de dados: 16
Autores: Stel, J.H.
Indonesia is the largest archipelago in the world (1.8 million km2 of land, 3.1 million km2 of sea, plus a 200 miles Exclusive Economic Zone covering some 2.7 million km2). Its population, ranking number four on the world list, amounts to more than 216 million people. Marine related programmes are given a high priority in Indonesia. During the last two decades the government has carried out a concerted effort in marine capacity building through bilateral, regional and international co-operation. This effort included increasing man-power development, expanding and improving research facilities, establishing a national marine data centre, improving co-operation within the Indonesian marine science community, and international co-operation. The bilateral...

Marine biodiversity of the coastal area of the Berau region, East Kalimantan, Indonesia : progress report East Kalimantan program, pilot phase (October 2003) : preliminary results of a field survey performed by an Indonesian-Dutch biodiversity research team
Provedor de dados: 16
Autores: Hoeksema, B.W.
The coastal waters of East Kalimantan are part of the western boundary of the Indo-West Pacific centre of maximum marine biodiversity. During the pilot phase of the East Kalimantan Program (EKP) this has been tested by various specialists who used model taxa to test this hypothesis. Emphasis has been put on the species-rich coral reefs and islands that show reef communities in association with mangroves, seagrass, and algae. A range of habitats has been surveyed, varying in distance offshore (with decreasing salinity, turbidity, sedimentation and nutrient load): fringing reefs along the mainland shore, offshore patch reefs, delta-front barrier reefs, and uplifted atolls. The atolls consist of limestone rock and contain shallow enclosed marine lakes with a...

Non-indigenous marine and estuarine species in The Netherlands
Provedor de dados: 16
Autores: Wolff, W.J.
An overview is presented of non-indigenous marine and estuarine plant and animal species recorded from The Netherlands. In this list both exotic species from outside NW Europe and non-indigenous species from elsewhere in NW Europe are enumerated. Species that have been suggested to be non-indigenous in The Netherlands but for which insufficient evidence could be found are discussed shortly as well. The list is based mainly on literature data supplemented by own observations of the author. At least 99 plant and animal species have been introduced from elsewhere in the world. Another 13 species have been introduced from other parts of NW Europe. The third category of dubious non-indigenous species enumerates 37 species. The list is preceded by an...

Foraminiferal ecology in the Ria de Arosa, Galicia, Spain
Provedor de dados: 16
Autores: Voorthuysen, J.H. van.
SUMMARY The Ria de Arosa is a large inlet of the Atlantic in western Galicia, NW Spain. It is little influenced by river discharge, the salinity is therefore the normal one for sea water, 33-36°/oo. According to Cadée (1968) the rocks exposed on the coast are for for the greater part granites; the rest, especially on the northwestern and northern coast, being gneisses and micaschists. Seven foraminiferal facies could be made. The L/D ratio is extremely low. It varies from zero to 18.5; the medium ratio is 2.3. Transport of shells from the continental shelf into the bay is rather high and more or less confined to the outer bayzone. The Recent foraminiferal fauna of the Arosa Bay has a fairly large number of species in common with the littoral Pliocene and...

Biological results of the Snellius expedition XXX : the foraminifera collected in 1929 and 1930 in the eastern part of the Indonesian Archipelago
Provedor de dados: 16
Autores: Hofker, J.
INTRODUCTION    Of the bottom material collected by the Snellius-Expedition 78 samples contained Foraminifera. Many of these samples were extremely small, since they were gathered by means of piston core samplers; some were larger, as they were collected by means of a dredge; others were samples in shallow water at beaches or reefs. A l l samples were fixed in formaldehyde, so that after the 40 years they remained in store before they were studied, rests of protoplasma were seldom preserved. The numerous plankton samples, preserved in formaldehyde or in alcohol, did note contain planktonic Foraminifera; obviously the small amount of CaC03 in the samples caused the dissolution of the tests.  The planktonic Foraminifera are not described here, as planktonic...

The distribution and diversity of whales and dolphins (Cetacea) in the southern North Sea: 1970-2005
Provedor de dados: 16
Autores: Meij, S.E.T. van der; Camphuysen, C.J.
Between 1970 and 2005 sightings data of cetaceans in the southern North Sea were collected as part of the Marine Mammal Database of the Dutch Seabird Group. The data include incidental sightings and reports as well as results from systematic surveys and seawatching data. They are therefore difficult to correct for fluctuations in observer effort. The material was evaluated firstly to see which species occur in Dutch waters and, secondly, to see if any spatial and temporal trends in abundance can be observed. In this study the harbour porpoise (Phocoena phocoena) is excluded from the analysis, except in the discussion, where the results are put into context with data about strandings and overall abundance. The status of the 17 different species that have...
