Small prey fight back: post-capture defences shape prey–predator size relationships [PDF]

Scientific Reports
Size relationships between prey and predators are a key topic in ecology. A positive correlation often exists between the sizes of prey and predators. Although predators can consume much smaller prey, some preferentially target larger prey and avoid very

Efficacy of indigenous larvivorous fishes against Culex quinquefasciatus in the presence of alternative prey: Implications for biological control [PDF]

Journal of Vector Borne Diseases, 2012
Background & objectives: Indigenous larvivorous fishes bear potential for regulating vector mosquitoes throughtrophic interactions. The mosquito prey preference of five indigenous larvivorous fishes in the presence of alternativefood items was assessed ...

Dynamics of harvested-predator–prey model: role of alternative resources [PDF]

Modeling Earth Systems and Environment, 2016
In this paper, A predator–prey model with square root functional response for herd behaviour of prey incorporating predator harvesting is proposed and analysed. The predator population is provided with alternative resource. The proposed model is demonstrated in respect of theoretical as well as numerical results.

A focus on long-run sustainability of a harvested prey predator system in the presence of alternative prey.

Comptes Rendus. Biologies, 2010
Within the framework of a general equilibrium model we study the long-run dynamics of a prey-predator model in the presence of an alternative prey. Our results show that sustainability, i.e. a positive value of the population in the long run, essentially depends on individual harvesting efforts and digesting factors relative to alternative prey.

Use of Amphipods as alternative prey to culture cuttlefish (Sepia officinalis) hatchlings.

Aquaculture, 2010
article i nfo The effects of feeding two alternative live prey (exclusively caprellids (Caprella equilibra) or several species of gammarids, mainly Ericthonius brasiliensis, Jassa marmorata and Elasmopus sp.), to cuttlefish hatchlings were compared to ...

Vulnerability of the mosquito larvae to the guppies (Poecilia reticulata) in the presence of alternative preys [PDF]

Journal of Vector Borne Diseases, 2008
Background & objectives: The predatory potential of the larvivorous fishes can be affected by the presence of alternative preys. In the present study the predation pattern of the sewage dwelling Poecilia reticulata (Peters 1872) on the larvae of Culex ...

Pronounced Seasonal Diet Diversity Expansion of Golden Eagles (Aquila chrysaetos) in Northern Greece during the Non-Breeding Season: The Role of Tortoises

Diversity, 2022
Golden Eagles are resident in Greece and known to feed mainly on tortoises when breeding. However, information on alternative prey is scarce, especially during the tortoise brumation, that roughly coincides with the eagles’ non-breeding season.

Direct and indirect effects of banker plants on population establishment of Harmonia axyridis and aphid control on pepper crop

Frontiers in Plant Science, 2022
Banker plant systems increase biological pest control by supporting populations of natural enemies, i.e., using non-pest arthropod species as alternative prey.

An alternating active-dormitive strategy enables disadvantaged prey to outcompete the perennially active prey through Parrondo’s paradox [PDF]

BMC Biology, 2021
Abstract Background Dormancy is widespread in nature, but while it can be an effective adaptive strategy in fluctuating environments, the dormant forms are costly due to the inability to breed and the relatively high energy consumption.

A simple predator–prey model of exploited marine fish populations incorporating alternative prey [PDF]

ICES Journal of Marine Science, 1996
A simple two-species population model in which the predator is partially coupled to the prey is developed. The model is an extension of traditional two-species models but less complex than a three-species system. The growth rate of the predator depends upon predation on the modeled and alternate prey; this formulation provides greater realism in ...
