Résumé :

Abstract Spider mites (Tetranychidae) are among the most injurious pests of commercial landscape plant nurseries. The introduction of predaceous mites (Phytoseiidae) into nursery crops for control of spider mites can be an effective alternative to pesticides. We sought to evaluate the use of banker plants as a method of rearing and dispersing predatory mites for the control of spider mites in landscape nursery systems. Banker plants include any plant addition that aids in development and dispersal of predators for control of herbivorous pests. Addition of the predatory mite Neoseiulus fallacis

Résumé :

Predator impacts on prey diversity are often studied among higher organisms over short periods, but microbial predator-prey systems allow examination of prey-diversity dynamics over evolutionary timescales. We previously showed that Escherichia coli commonly evolved minority mucoid phenotypes in response to predation by the bacterial predator Myxococcus xanthus by one time point of a coevolution experiment now named MyxoEE-6. Here we examine mucoid frequencies across several MyxoEE-6 timepoints to discriminate between the hypotheses that mucoids were increasing to fixation, stabilizing around

Résumé :

Predatory animals have evolved to optimally detect their prey using exquisite sensory systems such as vision, olfaction and hearing. It may not be so surprising that vertebrates, with large central nervous systems, excel at predatory behaviors. More striking is the fact that many tiny insects, with their miniscule brains and scaled down nerve cords, are also ferocious, highly successful predators. For predation, it is important to determine whether a prey is suitable before initiating pursuit. This is paramount since pursuing a prey that is too large to capture, subdue or dispatch will generat

Résumé :

In this work, we present sufficient conditions to determine if the limit cycles of certain differential systems in the plane are algebraic or not. In particular, we obtain criteria such that the limit cycles of equations derived from predatory prey models with rational functional response are necessarily transcendental ovals.

Résumé :

Biological control is an important ecosystem service for soil and plant health and has been successfully exploited, especially through augmentative biological control programs, for above-ground agricultural pest control often using predatory mites of Mesostigmata. Similar success has not been achieved for below-ground systems. Predatory mites are an important part of soil food webs, in which they have a regulatory impact. While this is mediated by the predator on the prey, recent studies suggest that biocontrol efficiency can be enhanced in the mid to long term for generalist predators by the

Résumé :

ABSTRACT Bdellovibrio bacteriovorus is a species of unique obligate predatory bacteria that utilize gram-negative bacteria as prey. Their life cycle alternates between a motile extracellular phase and a growth phase within the prey cell periplasm. The mechanism of prey cell invasion and the genetic networks and regulation during the life cycle have not been elucidated. The obligate predatory nature of the B. bacteriovorus life cycle suggests the use of this bacterium in potential applications involving pathogen control but adds complexity to the development of practical genetic systems that ca

Résumé :

The study of animal behaviour is important for both ecology and ecotoxicology, yet research in these two fields is currently developing independently. Here, we synthesize the available knowledge on drug-induced behavioural alterations in fish, discuss potential ecological consequences and report results from an experiment in which we quantify both uptake and behavioural impact of a psychiatric drug on a predatory fish ( Perca fluviatilis ) and its invertebrate prey ( Coenagrion hastulatum ). We show that perch became more active while damselfly behaviour was unaffected, illustrating that behav

Résumé :

AbstractIn vertebrates, it has been shown that binocular visual experience is necessary to develop normal spatial vision. We have investigated whether this is also true for an invertebrate, the praying mantis. The praying mantis is a predatory insect in which prey localization involves the use of binocular disparities. We raised mantids which had one eye occluded throughout development and tested monocular visual fixation and binocular distance estimation in the adult animals. The results revealed that both fixation and prey catching behavior were normally functional in the monocularly reared

Résumé :

<p>From the perspective of ecological control, harvesting behavior plays a crucial role in the ecosystem natural cycle. This paper proposes a diffusive predator-prey system with predator harvesting to explore the impact of harvesting on predatory ecological relationships. First, the existence and boundedness of system solutions were investigated and the non-existence and existence of non-constant steady states were obtained. Second, the conditions for Turing instability were given to further investigate the Turing patterns. Based on these conditions, the amplitude equations at the thresh

Résumé :

Scalar hyperbolic balance laws in several space dimensions play a central role in this thesis. First, we deal with a new class of mixed parabolic-hyperbolic systems on all R^n: we obtain the basic well-posedness theorems, devise an ad hoc numerical algorithm, prove its convergence and investigate the qualitative properties of the solutions. The extension of these results to bounded domains requires a deep understanding of the initial boundary value problem (IBVP) for hyperbolic balance laws. The last part of the thesis provides rigorous estimates on the solution to this IBVP, under precise reg

Résumé :

Predator-prey interactions form an essential part of ecological communities, determining the flow of energy from autotrophs to top predators. The rate of predation is a key regulator of that energy flow, and that rate is determined by the functional response. Functional responses themselves are emergent ecological phenomena – they reflect morphology, behavior, and physiology of both predator and prey and are both outcomes of evolution and the source of additional evolution. The functional response is thus a concept that connects many aspects of biology from behavioral ecology to eco-evolutiona

Résumé :

Abstract Ecologists often seek generalizations about the structure and dynamics of communities in predator-prey interactions, because simple logic demands a causal relationship between the extent of predation and state of the prey population. In tightly coupled systems, such as those envisaged by the Lotka-Volterra equations, the relationship between predator and prey population is mutual, but with increasing polyphagy, the interaction becomes diffuse, with specific prey perhaps having little influence on the abundance of the predator. Either way, it is easy to imagine that details of predator

Résumé :

Abstract Active detection of food items by echolocation has some obvious advantages over passive detection, since it affords independence from ambient light and sound levels. For predatory animals, however, echolocation would also appear to have a significant disadvantage-the echolocation calls might alert prey to the predator’s presence. Surprisingly, therefore, all but two of the different groups of vertebrates that have evolved echolocation are predatory. Despite the diversity of predatory taxa in which echolocation has evolved it is still a relatively uncommon form of perception. It has be

Abstract Free-living copepods come in predatory, omnivorous and mostly herbivorous versions, with appropriate sensory systems and limb structures for obtaining those meals. Corycaeus species are among the few predators that see their prey, clasp them with antennae modified as claws, then scrape nutrition with rasping mouthparts. Euchaeta (and other genera) directionally sense the sources of micro-eddies from swimmers around them with innervated antennular setae. They lunge toward the eddy source, impaling it with saber-like setae on their maxillae and maxillipeds. Jeannette Yen studied the det

Abstract To place our research on the Glanville fritillary butterfly (Melitaea cinxia) in a historical perspective, consider the state of metapopulation ecology in 1990. The earlier history, reviewed by Hanski (19996), includes outstanding conceptual contributions by Wright (1940) in population genetics and evolution and by Nicholson (1933) and Andrewartha and Birch (1954) in population ecology. Several significant though somewhat isolated studies appeared in the 1950s and 1960s.

Résumé :

The western flower thrips (WFT), Frankliniella occidentalis (Pergande), is a serious widespread pest of vegetable and ornamental crops worldwide. Chemical control for Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) on floriculture or vegetable crops can be difficult because this pest has developed resistance to many insecticides and also tends to hide within flowers, buds, and apical meristems. Predatory bugs, predatory mites, and entomopathogenic nematodes are commercially available in both the US and Israel for control of WFT. Predatory bugs, such as Orius species, can suppre
