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（Predator-Prey Interactions Gordon Research Conference）
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...
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 ...
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 “...
Physical Basis of Prey Capture by Marine Heterotrophic Nanoflagellates
Physical Basis Prey Capture Marine Heterotrophic Nanoflagellates
2015/8/14
Heterotrophic nanoflagellates are an important consumer group within pelagic foodwebs and play a vital role in cycling carbon and nitrogen in the world's oceans. Most primary production passes either ...
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...
Feeding rates and prey : predator size ratios of the nauplii and adult females of the marine cyclopoid copepod Oithona davisae
predator size Feeding rates and prey
2014/11/28
We studied the feeding behavior of the nauplii and adult females of the marine cyclopoid copepod Oithona
davisae in the laboratory. Functional response experiments showed that O. davisae can feed on ...
Vulnerability of Logfin Inshore Squid (Loligo Pealeii) to Predation: The Influence of Relative Prey Size and Behavior
Marine Predation Size-selection
2014/10/23
Cephalopods provide forage to a wide range of predators in marine food-webs. Despite their ecological importance, a basic understanding of the mechanisms controlling predation risk and demand is lacki...
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...
Selectivity by planktivorous fish at different prey densities, heterogeneities, and spatial scales
different prey densities heterogeneities spatial scales
2014/4/2
Studies in artificially confined, small-scale experimental systems with a homogeneous prey distribution suggest
that selectivity in planktivorous fish for more conspicuous and rewarding prey (such as...
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...
Effect of prey refuge on the dynamics and equilibrium density of
Predator-prey models Stability Limit cycles Prey refuge
2011/10/20
In this paper, we use an analytical approach to study the dynamics of the simplest forms of refuge using by prey. Here we incorporate prey refuge in a widely known continuous model|the Lotka-Volterra ...
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 ...
