Trophic interactions drive diel vertical migration patterns

Using a game theoretic and mechanistic model, researchers from the Centre for Ocean Life showed how traits influencing predator-prey interactions shape the diel vertical...

DTU professor awarded Carlsberg Foundation Research Prize 2019

Thomas Kiørboe, Professor of Ocean Ecology at DTU, receives research prize for his groundbreaking work.

Salmon

Optimal Salmon Lice Treatment and Tragedy of the Commons

Sea lice on salmon farms are controlled via treatments. Authorities mandate treatments when sea lice infections reach a given threshold. Using a bio-economic model, we...

Planktonic encounter rates with non-spherical encounter zones

Planktonic encounter rates with non-spherical encounter zones

A new theoretical approach makes it possible to model planktonic predator-prey interactions and quantify the effects of the encounter zone shape for both non-motile and...

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...

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 are...

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...

Diatoms

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...

Evolution of reproductive strategies in jellyfish
01 MAR

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...

Plankton communities
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 the...

Diatom
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...

Temperature response of unicellular plankton communities
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...

Illustration of climate change-induced shifts in the distribution of plankton alter the global carbon cycle
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.

Phytoplankton abundance drives behavior mediated cascades in marine food webs
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...

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 since...

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...

Pelagic copepods
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...

Big fish mamas

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...

Flagellates
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 studied...
