Data from: Bottom trawling affects fish condition through changes in the ratio of prey availability to density of competitors
负责人:
Hiddink, Jan
关键词:
Otter trawl Beam trawl ecosystem effects of fishing Kattegat Marine protected area density dependence
摘要:
Bottom-trawl fisheries are widespread and cause mortality of benthic invertebrates, which in turn may lead to a decrease in the availability of prey
Data from: The effect of uncertain bottom friction on estimates of tidal current power

摘要:
h as the Pentland Firth, UK. We examine the role of bottom friction, one of the most important sources of uncertainty. We do so by using perturbation methods
Data from: Bottom time does not always predict prey encounter rate in Antarctic fur seals

摘要:
Optimal foraging models applied to breath-holding divers predict that diving predators should optimize the time spent foraging at the bottom of dives
Data from: Assessing bottom-trawling impacts based on the longevity of benthic invertebrates

摘要:
1. Bottom trawling is the most widespread human activity directly affecting seabed habitats. Assessment and effective management of the effect
Data from: Priority effects are interactively regulated by top-down and bottom-up forces: evidence from wood decomposer communities
负责人:
关键词:
摘要:
Both top-down (grazing) and bottom-up (resource availability) forces can determine the strength of priority effects, or the effects of species
Data from: The changing contribution of top-down and bottom-up limitation of mesopredators during 220 years of land use and climate change
负责人:
Pasanen-Mortensen, Marianne
关键词:
Ecosystem processes Historical ecology Historical maps Intraguild killing Trophic interactions Wildlife monitoring Wildlife restoration
摘要:
Apex predators may buffer bottom-up driven ecosystem change, as top-down suppression may dampen herbivore and mesopredator responses to increased
Data from: Extreme diel dissolved oxygen and carbon cycles in shallow vegetated lakes

关键词:
shallow vegetated lakes;charophytes;recurring stratification-mixing;diel carbon cycles;diel dissolved oxygen cycles;daytime anoxia;Holocene
摘要:
attenuates light and turbulence generating separation between warm surface waters and much colder bottom waters. Photosynthesis in surface waters produces
Data from: Sex differences in risk perception in deep-diving bottlenose dolphins leads to decreased foraging efficiency when exposed

摘要:
of surface and bottom dives and the frequency of estimated bottom dives. 3. Males significantly increased bottom time and performed fewer bottom dives
