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...

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 are...

02 MAY

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...

29 APR

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 the...

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...

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 since...

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...

10 JAN

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 studied...

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...

Happy Christmas and one final achievement for the year

After a wonderful annual retreat and Christmas party, it is now time to wish everyone a lovely Christmas and for most, safe travels to their home country.

18 DEC

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.
