Biodiversity-ecosystem functioning relationships in demersal fish communities

While the planet experiences unprecedented human-induced biodiversity loss, from marine to terrestrial realms, and from microbes to large mammals, evidence that biodiversity...

13 JUN

Dense dwarfs versus gelatinous giants

A new theoretical model describes the trade-offs and physiological limits determining the body plan of planktonic filter feeders and explains why gelatinous plankton...

A trait collection of marine fish species

We compiled 14 traits of 1700 marine fish species on three latitudinal gradients to facilitate large-scale studies on fish traits and functional diversity of fish communities...

Silicified cell walls as a defensive trait in diatoms

Diatoms contribute nearly half of the marine primary production. These microalgae differ from other phytoplankton groups in having a silicified cell wall, which is the...

Honorable mention by the American Naturalist for our paper on evolution of reproductive...

Jellyfish are weird creatures that can reproduce in different modes both sexually and asexually. Similar functional strategies are also present in several other species...

25 FEB

Competition-defense tradeoff increases the diversity of microbial plankton communities...

Defense mechanisms are very common in unicellular plankton. A wide variety of these mechanisms (toxins, shell etc.) is observed and it is rather difficult to quantify...

22 FEB

Why are diatoms so successful?

A mechanistic model of diatoms reveals a conundrum. The defining physical attributes of diatoms – their silica shell and their large central vacuole – give diatoms an...

12 FEB

Resource limitation determines temperature response of unicellular plankton communities

Increases in temperature increase enzymatic activity, so one expects growth to also increase. However, this is not always the case. We show that when organisms are resource...

12 FEB

Climate change-induced shifts in the distribution of plankton alter the global...

Changes in the distribution of zooplankton in the North Atlantic during the past 55 years has led to major changes in the biological carbon pump.

07 FEB

When more is less: phytoplankton abundance drives behavior mediated cascades in...

Our traditional view of the interactions between marine organisms is conceptualized as food webs where species interact with one another mainly via direct consumption...

05 FEB

Changes in community traits of North Sea fish not similar in time and space

The North Sea fish community has a long history of intense fishing and environmental change. Scientific bottom trawl surveys, which have been ongoing in the North Sea...

28 JAN

Non-mechanistic traits and false trade-offs

Trade-offs are the cornerstone of trait-based ecology. They describe the advantages and costs of a certain trait, and thus determine when and where organisms with that...

21 JAN

New study identifies rapid developmental shifts in the thermal sensitivity of...

Ectotherms often grow to a smaller adult body size when reared in warmer conditions. Typically, this is because development rate increases faster than growth rate with...

Limited impact of big fish mothers for population replenishment

A new paper from the Center for Ocean Life shows that the implications of a recent Science paper by Barneche et al. (Science 360(6389): 642) are much less dramatic than...

10 JAN

Why are some flagellates living in a ribbon case?

Choanoflagellates are filter feeders and an important component of microbial foodwebs. Because they are the ancestors of multicellular life, they have been intensely...

04 JAN

Predator prey games in multiple habitats reveal mixed strategies in diel vertical...

Can we apply economic principles to fish ecology and diel vertical migration? It appears that the way fish and zooplankton behave in the presence of other individuals can...

The global biogeography of zooplankton foraging traits

Do zooplankton traits matter? Scaling up trade-offs to the global scale. Taxa-transcending traits and trade-offs have been shown through lab experiments and literature...

7th Annual Meeting of the Centre for Ocean Life

Centre's annual retreat took place in Hohenwarte 10-13 December to summarize the scientific success of 2018 and discuss future directions.

22 NOV

How does the trait distribution change between oligotrophic and eutrophic pelagic...

When we look at nutrient poor (oligotrophic) and nutrient rich (eutrophic) ecosystem, we generally observe different species. We can therefore conclude that these ecosystems...

24 AUG

Copepods avoid eating Toxic Algae

Copepods avoid eating most toxic dinoflagellates and thus the toxin efficiently protects the algae against grazing

15 AUG

New paper: Modelling the cost of toxin production in phytoplankton

Is toxin production in phytoplankton costly? How do environmental conditions affect the cost of toxin production?

13 AUG

The trait based approach to Ocean Ecology

Marine ecosystems are overwhelmingly complex. The trait-based method offers a simple way to describe, model, and understand complex marine systems. In a new paper we...

06 AUG

New paper: Prey perception mechanism determines maximum clearance rates of planktonic...

What zooplankton foraging strategy is more efficient in terms of volume of water cleared? What mechanism determines clearance efficiency of zooplankton foraging strategies...

01 MAY

Crude oil spills can cause the initiation of harmful algal blooms (“red tides...

After oil spills and dispersant applications, the formation of red tides or harmful algal blooms (HABs) has been observed, but the link between both phenomena was unknown...

21 MAR

Global mismatch in marine conservation protection

A new Ocean Life paper demonstrates a global mismatch in the protection of multiple marine biodiversity components and ecosystem services.

24 JAN

Flying Copepods

Some copepods, mm-sized zooplankton, that live in the very surface layer of the ocean jump out of the water and perform spectacular flights when escaping from predators...

Defence mechanisms in phytoplankton: traits and trade-offs

New review experimentally exploring plankton defense mechanism

22 JAN

Implications of late-in-life density-dependent growth for fishery size-at-entry

Density dependence is the major driving force behind population regulation. Here we looked at density-dependent growth in real-life fish stocks, and how this relates...

17 JAN

How do copepods respond to toxic prey? And can the copepods acclimate to algal...

Many species of phytoplankton produce substances that are toxic to both human consumers and planktonic grazers, and toxin production is often considered a defense mechanism...

08 JAN

PhD positions at the Centre for Ocean Life

Centre for Ocean Life offers 3-year PhD fellowships in experimental plankton ecology and trait-based modelling within the general topic of trait-based Marine Ecology. The...

05 JAN

Temporal and spatial differences between taxonomic and trait biodiversity in a...

Biodiversity is a multifaceted concept, yet most biodiversity studies have taken a taxonomic approach, implying that all species are equally important. However, species...

6th Annual Meeting of the Centre for Ocean Life

Centre's annual retreat took place 13-14/12 in Faxe to summarize the scientific success of 2017.

04 DEC

How do food-webs respond to climate change?

To understand the effects of climate change on changing ocean biomass, understanding how different species interact is a difficult but necessary task.

28 NOV

Global patterns in marine predatory fish

Why do we find primarily large pelagic predators such as tunas and billfish in the tropics, while in boreal and temperate regions large demersal species of gadoids and...

17 NOV

New paper on invasive species from ocean life

Life-history traits of comb jellies (Mnemiopsis) invaded to European waters start reproducing at a body mass 100 times less than in mother populations. This is consistent...

What are the spatial patterns of fish life history strategies in the European Seas and what are their main drivers?

New paper on trophic strategies of unicellular plankton

We have developed a trait-based model to describe how the size of organisms and the environmental conditions interact to determine trophic strategies of unicellular plankton...
