Long-term shifts in coral communities on shallow to deep reef slopes of Curaçao and Bonaire: are there any winners?

Autor: Didier M De Bakker, Erik HWG Meesters, Rolf PM Bak, Gerard Nieuwland, Fleur C van Duyl

Publikováno v: Frontiers in Marine Science, Vol 3 (2016)

Tropical coral reefs are among the most biologically diverse and economically important ecosystems on earth. Nevertheless, we found dramatic changes in coral communities on the reef slopes of Curaçao and Bonaire since 1973. Cover and abundance decli

The diet of cavity sponges on the narrow fringing reefs of Cura double dagger ao, Caribbean was studied. The origin and resources of the bulk food of these sponges, i.e., dissolved organic matter (DOM), were identified using stable carbon and nitroge

Coral reef crisis in deep and shallow reefs: 30 years of constancy and change in reefs of Curacao and Bonaire

Autor: Erik H. Meesters, Rolf P. M. Bak, Gerard Nieuwland

Publikováno v: Coral Reefs. 24:475-479

Coral reefs are thought to be in worldwide decline but available data are practically limited to reefs shallower than 25 m. Zooxanthellate coral communities in deep reefs (30-40 m) are relatively unstudied. Our question is: what is happening in deep

Removal of bacteria and nutrient dynamics within the coral reef framework of Curaçao (Netherlands Antilles)

Autor: Rolf P. M. Bak, Sander R Scheffers, Gerard Nieuwland, FC van Duyl

Publikováno v: Coral Reefs. 23:413-422

The authors studied removal rates of bacteria and the regeneration of inorganic nutrients in coral reef cavities in the reef slope of Curacao, Netherlands Antilles. We found that in cavities the hard substratum surface area (=ca 68% of cavity surface

RNA/DNA ratios of scleractinian corals suggest acclimatisation/adaptation in relation to light gradients and turbidity regimes

Autor: Erik H. Meesters, A. Kok, Gerard C.A. Duineveld, Rolf P. M. Bak, Gerard Nieuwland

Publikováno v: Marine Ecology Progress Series. 227:233-239

RNA/DNA ratios are used in many organisms as an indicator of growth, biomass or metabolic functioning. We hypothesised that hermatypic corals, as they depend for growth largely on energy transferred from their algal symbionts, may show an effect in t

Temporal and spatial variations in heterotrophic nanoflagellate abundance in North Sea sediments

Autor: Gerard Nieuwland, FC van Duyl, Bjm Hondeveld, Rpm Bak

Publikováno v: Marine Ecology Progress Series. 111:235-243

Summer-winter variations in marine nanoflagellate densities at 3 depths in North Sea sediment~ (0-3, 30-33 and 60-63 mm) were studied using epifluorescence microscopy. Benthic flagellate densities in summer ranged from 7 to 859 X lo3 and in winter fr

Bacteria, auto- and heterotrophic nanoflagellates, and their relations in mixed, frontal and stratified waters of the North Sea

Autor: Gerard Nieuwland, Rolf P. M. Bak, A.J. Kop, F.C. Van Duyl

Publikováno v: Netherlands Journal of Sea Research. 26:97-109

The horizontal and vertical distributions of bacteria and bacterial productivity were compared with nanoflagellate densities in the southern part of the central North Sea. Mixed, frontal and stratified waters were sampled in transects during summer 1
