The swimming sperm cell reminds us of our aquatic ancestors: the flagellates. While the sperm cell uses its flagellum solely for propulsion, flagellates use their flagellum also for foraging, making them the most important predators on bacteria and picophytoplankton in the ocean. A new review explores the fluid mechanics of predation in a microbial world.]]></description><pubDate>Tue, 18 Jul 2023 10:41:42 +0200</pubDate><guid>https://www.oceanlifecentre.dk/news/nyhed?id=1f25dd20-ac99-4020-9987-cb079ff30a24</guid></item><item><title>How does limitations set by physics constrain the primary production in the world’s oceans?</title><link>https://www.oceanlifecentre.dk/news/nyhed?id=808c8a1c-b065-4870-9b86-8cb0c052fa4d</link><description><![CDATA[<img src="https://www.oceanlifecentre.dk/-/media/sites/oceanlife/news/kenandysize.png?mw=220&hash=0E390A8B59A46A36D2A01E46243CB804" alt="" width="220" /><br />]]></description><pubDate>Wed, 15 Mar 2023 08:42:39 +0200</pubDate><guid>https://www.oceanlifecentre.dk/news/nyhed?id=808c8a1c-b065-4870-9b86-8cb0c052fa4d</guid></item><item><title>Fat copepods sequester carbon</title><link>https://www.oceanlifecentre.dk/news/nyhed?id=faa4994e-85ab-420e-ad7d-3e8adbf379e4</link><description><![CDATA[<img src="https://www.oceanlifecentre.dk/-/media/sites/oceanlife/news/st17_4_0091_2.jpg?mw=220&hash=12A168633AD5AD8B0942B99647C38BB0" alt="" width="220" /><br />New publication estimates that a significant amount of carbon (13 to 35 GtC) is sequestered in the deep oceans by seasonally migrating copepods. ]]></description><pubDate>Mon, 13 Mar 2023 09:09:37 +0200</pubDate><guid>https://www.oceanlifecentre.dk/news/nyhed?id=faa4994e-85ab-420e-ad7d-3e8adbf379e4</guid></item><item><title>Fast food: efficient prey handling in suspension feeding copepods</title><link>https://www.oceanlifecentre.dk/news/nyhed?id=2af8170c-4dd3-444e-a464-1df53756d932</link><description><![CDATA[<img src="https://www.oceanlifecentre.dk/-/media/sites/oceanlife/news/copepod.jpg?mw=220&hash=9B3C592F1E35319BB446D56B75D5BF1E" alt="" width="220" /><br />

Ecosystems are complex machineries, and our ability to predict how multiple drivers and environmental forcing structure communities are limited. One way to represent and understand organisms, communities and ecosystems is to think in terms of 'traits' rather than species, and how the dominant traits emerge in an evolutionary and ecological process from fundamental trade-offs. If we can identify and quantify the tradeoffs between traits, we may have a tool for predicting trait distributions in nature now and in the future. This workshop is the 6th edition of 'Trait-based approaches to Ocean Life', and now returns to Copenhagen, where the first workshop took place in 2013.

Diatoms are one of the most diverse groups of phytoplankton in the ocean. One reason for this high diversity is the evolution of multiple defence mechanisms and subsequent evolution of grazer “counter measures”. In a new study, we describe the discovery of yet another defence mechanism: when exposed to chemical cues from copepods several species become “sticky” and form rapidly sinking aggregates, allowing cells to hide in the sediment until growth conditions again become favourable.  ]]></description><pubDate>Mon, 26 Sep 2022 16:40:20 +0200</pubDate><guid>https://www.oceanlifecentre.dk/news/nyhed?id=8201c62b-9b6e-46ea-ae4c-032124bb970b</guid></item><item><title>The feeding behavior of Apocyclops royi</title><link>https://www.oceanlifecentre.dk/news/nyhed?id=d8594d50-e6e5-49b7-9ec2-a007e8ce6bc5</link><description><![CDATA[<img src="https://www.oceanlifecentre.dk/-/media/sites/oceanlife/news/2022/the-feeding-behavior-of-apocyclops-royi.tif?mw=220&hash=B7F66ED87E60E8616FA0CBFBDBD6F8AB" alt="" width="220" /><br />
Ambush-feeding copepods passively wait for its prey and capture them by a fast surprise attack. The copepods sense the hydromechanical signals generated by their motile prey. However, the ambush feeding copepod Apocyclops royi can be sustained on a diet of Baker’s yeast, which are small, non-motile cells. We asked how this ambush-feeding copepod can live on a small, non-motile cell. ]]></description><pubDate>Wed, 07 Sep 2022 09:45:36 +0200</pubDate><guid>https://www.oceanlifecentre.dk/news/nyhed?id=d8594d50-e6e5-49b7-9ec2-a007e8ce6bc5</guid></item><item><title>Hairy flagellates have a clever way to overcome limitations of life at small scales</title><link>https://www.oceanlifecentre.dk/news/nyhed?id=79e7b0ac-84e1-4ded-9bae-826626eb0a6c</link><description><![CDATA[<img src="https://www.oceanlifecentre.dk/-/media/sites/oceanlife/news/2022/hairy-flagellates.png?mw=220&hash=3516EAE3DEAAAFAA14CF7E61366EF61B" alt="" width="220" /><br />
Flagellates live in a small-scale environment where viscosity impedes contact with their bacterial prey. Most flagellates use the active waving motion of a flexible flagellum with hairs to generate a feeding current. The presence of hairs significantly increases the force generated by the flagellum and also reverses its direction, hence producing an efficient feeding current coming towards the flagellate. A recent paper from the Centre describes the underlying mechanism of the force production in hairy flagellates.]]></description><pubDate>Thu, 14 Jul 2022 13:32:11 +0200</pubDate><guid>https://www.oceanlifecentre.dk/news/nyhed?id=79e7b0ac-84e1-4ded-9bae-826626eb0a6c</guid></item><item><title>Evolution of toxicity as a public good in phytoplankton</title><link>https://www.oceanlifecentre.dk/news/nyhed?id=76e69ba5-b83f-4806-9731-a5261c677da0</link><description><![CDATA[<img src="https://www.oceanlifecentre.dk/-/media/sites/oceanlife/news/2022/evolution_of_toxicity.png?mw=220&hash=CFCC6D608491133F7D7933A85D40E092" alt="" width="220" /><br />
Many species of phytoplankton release toxins that combat competitors and predators. It has long puzzled researchers how such ‘public good’ toxicity has evolved, because mutant ‘cheaters’ that do not pay the cost of toxin production would benefit equally from the toxicity and thus outcompete the toxin producers. In a new study we describe how toxins as a public good may evolve.]]></description><pubDate>Wed, 22 Jun 2022 13:03:44 +0200</pubDate><guid>https://www.oceanlifecentre.dk/news/nyhed?id=76e69ba5-b83f-4806-9731-a5261c677da0</guid></item><item><title>Exploring the relation between the size spectrum of plankton communities and carbon export in the ocean</title><link>https://www.oceanlifecentre.dk/news/nyhed?id=13bc3553-f840-42e8-94fc-2402604006bd</link><description><![CDATA[<img src="https://www.oceanlifecentre.dk/-/media/sites/oceanlife/news/2022/camilla.png?mw=220&hash=9E39981F3A10F1D1E8BBE1869329C5EA" alt="" width="220" /><br />
In the oceans, a nearly constant biomass of organisms is found in equal log- intervals of body-size. This large-scale regularity is referred to as the size spectrum. In this new modelling study, we find that parameters of the size spectrum correlate strongly with the export and export efficiency of particles into the deep ocean. These parameters performed better than other commonly used export predictors such as temperature or primary production.]]></description><pubDate>Thu, 05 May 2022 10:10:07 +0200</pubDate><guid>https://www.oceanlifecentre.dk/news/nyhed?id=13bc3553-f840-42e8-94fc-2402604006bd</guid></item><item><title>How do flagellates feed: Mystery solved</title><link>https://www.oceanlifecentre.dk/news/nyhed?id=e725a5d2-d72e-4693-a056-ce0e72bec80e</link><description><![CDATA[<img src="https://www.oceanlifecentre.dk/-/media/sites/oceanlife/news/2022/flagellates.jpg?mw=220&hash=6910C019311818EEA28DB1922FC32D8F" alt="Mechanisms and fluid dynamics of foraging in heterotrophic nanoflagellates" width="220" /><br />

The bloom-forming diatom Pseudo-nitzschia produces a potent neurotoxin, domoic acid, that may cause closure of fisheries. The reason for its production has long been under debate. In a new study (in collaboration with the Natural History Museum of Denmark) we demonstrate a ‘private-good’ benefit to producing the toxins as toxic cells are more frequently rejected by grazing copepods. However, the production of toxins comes at a cost to the cells in terms of reduced growth rate. ]]></description><pubDate>Wed, 13 Apr 2022 11:57:42 +0200</pubDate><guid>https://www.oceanlifecentre.dk/news/nyhed?id=b93330c7-868e-4b5e-9679-681d74793f76</guid></item><item><title>Species Specific Responses to Grazer Cues and Acidification in Phytoplankton- Winners and Losers in a Changing World</title><link>https://www.oceanlifecentre.dk/news/nyhed?id=ac3253e9-c297-43e9-84c8-7910fa513a8d</link><description><![CDATA[<img src="https://www.oceanlifecentre.dk/-/media/sites/oceanlife/news/2022/figureoa.jpg?mw=220&hash=9D567DAAFFD182E5173DB410295AF758" alt="" width="220" /><br />
Phytoplankton employ a wide variety of defense against grazers, and rely on chemical cues to assess the current grazing pressure. However, these signals are potentially vulnerable to environmental change, such as ocean acidification. In a collaboration with the Marine Chemical Ecology group at the University of Gothenburg, Sweden, Ocean Life researchers have tested if ocean acidification can alter the chemical signals released by copepod grazers.  ]]></description><pubDate>Fri, 08 Apr 2022 13:56:07 +0200</pubDate><guid>https://www.oceanlifecentre.dk/news/nyhed?id=ac3253e9-c297-43e9-84c8-7910fa513a8d</guid></item><item><title>Predator field and colony morphology determine the defensive benefit of colony formation in marine phytoplankton</title><link>https://www.oceanlifecentre.dk/news/nyhed?id=f8f0c559-6427-4083-80d4-8d4ef41e7ed1</link><description><![CDATA[<img src="https://www.oceanlifecentre.dk/-/media/sites/oceanlife/news/2022/fredrik2022_04.png?mw=220&hash=AD960FB4EFF0FC65303B1B88B818E0CA" alt="" width="220" /><br />

In most organisms foraging implies elevated exposure to predators. Such foraging trade-offs are universal and are main determinants of the structure and function of ecosystems. Yet, in few organisms have such trade-offs been quantified. In a new paper published this week in PNAS we demonstrate for the smallest predators in the ocean - unicellular flagellates - that those species that most efficiently clear the ambient water for prey also run the highest predation risk, and we quantify this foraging trade-off.]]></description><pubDate>Thu, 14 Jan 2021 13:50:23 +0200</pubDate><guid>https://www.oceanlifecentre.dk/news/nyhed?id=d9a21fbd-5e51-45f5-ad8c-ea73b47c44fc</guid></item><item><title>Feeding flows of microorganisms attached to solid surfaces</title><link>https://www.oceanlifecentre.dk/news/nyhed?id=9697290a-f6dc-4cdd-b961-841b6829d0e4</link><description><![CDATA[<img src="https://www.oceanlifecentre.dk/-/media/sites/oceanlife/news/2020/oceanlifeweb.png?mw=220&hash=7133DC38FF3A265B66BFAC60D56FE5B8" alt="" width="220" /><br />

This is demonstrated in a new paper published online today in PNAS analyzing data from more than 500 species, aquatic and terrestrial, and from single celled organisms to birds and mammals.]]></description><pubDate>Thu, 24 Sep 2020 09:54:09 +0200</pubDate><guid>https://www.oceanlifecentre.dk/news/nyhed?id=5e20d2e1-3e1f-44c1-aeb4-ba13247df0ed</guid></item><item><title>Fish are neither right- nor left-brained</title><link>https://www.oceanlifecentre.dk/news/nyhed?id=54585f22-2f0e-4b0d-80d8-fa25765e5378</link><description><![CDATA[<img src="https://www.oceanlifecentre.dk/-/media/sites/oceanlife/news/2020/tommy_paper_brainfish.png?mw=220&hash=8C617DEF8B86452482297E4A475A4DB3" alt="Illustration of whether fishes are right- or left-brained" width="220" /><br />]]></description><pubDate>Mon, 31 Aug 2020 11:04:50 +0200</pubDate><guid>https://www.oceanlifecentre.dk/news/nyhed?id=54585f22-2f0e-4b0d-80d8-fa25765e5378</guid></item><item><title>New book on fish physiology</title><link>https://www.oceanlifecentre.dk/news/nyhed?id=976c508a-24cc-4174-93f5-895b148c984b</link><description><![CDATA[<img src="https://www.oceanlifecentre.dk/-/media/sites/oceanlife/news/2020/picturetommy.png?mw=220&hash=B47E71523B67B73022DD55508042A9D4" alt="Illustration fishes as abundant and diverse vertebrates." width="220" /><br />
With over 30,000 species, fishes are the most abundant and diverse vertebrates on the planet. This new edition of the textbook ‘The Physiology of Fishes’ explores and explains how fish work, how they adapt and thrive in such a wide range of habitats on earth, and how global change may affect their continued success. Dr Tommy Norin, a researcher at the Centre for Ocean Life, has contributed with a chapter on fish metabolism.]]></description><pubDate>Thu, 27 Aug 2020 14:37:20 +0200</pubDate><guid>https://www.oceanlifecentre.dk/news/nyhed?id=976c508a-24cc-4174-93f5-895b148c984b</guid></item></channel></rss>
