Predators and hidey-holes are good for coral reef fish populations（图）
Predators hidey-holes coral reef fish populations
2019/10/17
New NSF-funded research by NC State scientists highlights two factors that play critical roles in supporting reef fish populations, and ultimately in creating conditions that are more favorable for th...
To find out how invading predators change an ecosystem, watch their prey（图）
invading predators change ecosystem watch their prey
2019/10/28
Invading predators can devastate an ecosystem. In fact, a leading cause of extinction is the introduction of predators into an isolated place like an island or a lake.The destruction is usually blamed...
Drill holes in fossil shells point to bigger predators picking on small prey
Drill holes fossil shells point predators picking small prey
2017/7/21
The drill holes left in fossil shells by hunters such as snails and slugs show marine predators have grown steadily bigger and more powerful over time but stuck to picking off small prey, rather than ...
Study:Predators can drive increase in virus populations
Predators drive increase virus populations
2016/11/29
Publishing in the journal Proceedings of the National Academy of Sciences, the study’s authors have reported the first evidence that a predator’s consumption of prey can catalyze the natural rise and ...
The Roles of Large Top Predators in Coastal Ecosystems: New Insights from Long Term Ecological Research
New Insights Long Term Ecological Research
2015/7/16
During recent human history, human activities such as overhunting and habitat destruction have severely impacted many large top predator populations around the world. Studies from a variety of ecosyst...
The once-booming, now struggling Olympia oyster native to the West Coast could face a double threat from ocean acidification and invasive predators, according to new research from the University of Ca...

Nutrient enrichment differentially affects body sizes of primary consumers and predators in a detritus-based stream
Nutrient enrichment differentially affects body sizes predators
2014/4/17
We assessed how a 5-yr nutrient enrichment affected the responses of different size classes of primary
consumers and predators in a detritus-based headwater stream. We hypothesized that alterations i...
Isotopic niches and trophic levels of myctophid fishes and their predators in the Southern Ocean
Isotopic niches trophic levels myctophid fishes their predators in the Southern Ocean
2014/4/16
We report the trophic structure of a myctophid assemblage by measuring theisotopic niches of 14 species living in Kerguelen waters, southern Indian Ocean. Most of the species show distinct isotopic ni...
No empirical evidence for community-wide top-down control of prey fish density and size by fish predators in lakes
No empirical evidence community-wide top-down control prey fish density size by fish predators in lakes
2014/4/16
I tested relationships between fish predator and prey densities or size across 66 lakes of the European temperate zone, covering mean depths between 1 and 22 m and a phytoplankton biomass range betwee...
Two-step dialogue between the cladoceranBosminaand invertebrate predators: Induction and natural selection
Two-step dialogue cladocera Bosmina invertebrate predators: Induction natural selection
2014/4/16
Aquatic prey species respond to predators with fast (developmental) and slow (selective) feedbacks. Natural selection is assumed to fashion details of induction and to modify baseline morphology, but ...
Plastic phenotypes of antennule shape in Bosmina longirostris controlled by physical stimuli from predators
antennule shape Bosmina longirostris controlled
2014/4/22
Three antennule morphotypes in the small cladoceran Bosmina longirostris have been considered to be
hereditarily rigid phenotypes. However, we found that monoclonal populations of Bosmina collected f...
Selective predators and their parasitized prey: Are epidemics in zooplankton under top-down control?
Selective predators parasitized prey epidemics in zooplankton top-down control
2014/5/9
Seasonal change in the intensity of fish predation affects succession in lake zooplankton communities. Predation affects not only the zooplankton prey, but also their parasites. Because the ability of...

The assumption that macrophytes can provide zooplankton a daytime refuge against fish predation is central to
the diel horizontal migration hypothesis. However, previous observations and experi...
