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...

2018年 捕食者与猎物的相互作用戈登研究 会议
2018/1/12
The 2018 Gordon Research Conference on Predator-Prey Interactions brings together speakers from a range of disciplines to address both the underlying mechanisms and emergent impacts of the predator-pr...
In Harm's Way:Wolves May Not Risk 'Prey Switching' say USU Ecologists
Wolves May Not Risk Prey Switching USU Ecologists
2017/4/27
Ecologists have long observed predators pursue disproportionately more of a plentiful prey species, and less of scarce prey, but change to the latter if it becomes relatively more abundant. Known as “...
Usual prey gone, a fish survives by changing predictably
prey gone fish survives changing predictably
2015/3/18
CLEVELAND—A species of fish that normally eats smaller fish changes in predictable ways when isolated from its prey, research led by a Case Western Reserve University biologist found.Without the Baham...
Invertebrate Phenology and Prey Selection of Three Sympatric Species of Salmonids; Implications for Individual Fish Growth
Invertebrate Phenology Prey Selection Three Sympatric Species Salmonids Individual Fish Growth
2014/12/12
Growth plays an important roll in the survival of individual salmonid fish. Diet inevitably plays a significant role in the determination of salmonid growth, with these diets consisting primarily of a...
Sharks sense prey in surprising ways during pioneering study
Sharks sense prey in surprising ways during pioneering study
2014/4/16
A team of scientists have unmasked the intricacies of how sharks hunt prey — from the first whiff to the final chomp —in a new study about shark senses that was supported by the National Science Found...
The Effect of Differentiation of Prey Community on Stable Coexistence in a Three-Species Food--Web Model
Intraguild predation Immobilization Alternative resource Multiple resource traits Stable coexistence
2012/4/28
Food webs with intraguild predation (IGP) are widespread in natural habitats. Their adaptation and resilience behaviour is principal for understanding restructuring of ecological communities. In spite...
Existence of Periodic Solution for a Predator-prey System with Feedback Control
Hassell-Varely type predator-prey coincidence degree theorem Lyapunov function global stability
2012/9/24
A Hassell-Varely type predator-prey system with feedback controls is studied. Using the comparison, continuation theorems and coincidence degree theorem, the existence of positive periodic solutions f...
Existence and Uniqueness of the Positive Solution to a Predator-prey Model with Stochastic Perturbation
Itos formula Brownian motion existence and uniqueness
2012/9/24
In this paper, a predator-prey model is estab lished with the modified Holling-type II schemes with stochastic perturbation. We mainly use Lyapun ov function and comparison theorem to show that there ...
New DNA database to protect endangered birds of prey（图）
DNA Nottingham Trent University endangered birds of prey
2009/5/4
The collaboration - thought to be the first of its kind in the UK – will catalogue DNA profiles from genetic material extracted from feathers, cheek swabs, droppings and even egg shell. DNA samples wi...
Efficiency of fish feeding on plant-attached prey: Effects of inorganic turbidity and plant-mediated changes in the light environment
Efficiency of fish feeding plant-attached prey Effects of inorganic turbidity plant-mediated changes light environment
2014/5/4
We studied the effects of inorganic turbidity on the efficiency of perch (Perca fluviatilis) feeding on the cladoceran Sida crystallina attached to floating macrophyte leaves together with the effects...
Prey Selection by African Catfish Clarias gariepinus (Burchell, 1822) Larvae Fed Different Feeding Regimes
Clarias gariepinus prey selectivity rotifer copepod betaine
2010/3/26
Live prey selection by African catfish, Clarias gariepinus, larvae was examined under laboratory conditions. Larvae were offered plankton, plankton + trout starter (TS) and plankton + betaine suppleme...
Some Observations on Gastric Emptying in the Black Sea Whiting, Merlangius merlangus euxinus, (N. 1840) Fed on Natural Prey
Black Sea Whiting Return of Appetite Gastric Emptying Time (GET)
2010/4/1
In this study a new perspective on the feeding physiology of whiting, Merlangius merlangus euxinus, N. 1840 was investigated. The effects of the skin of the prey, double feeding and prey type on the g...
