1. Apparent competition leaves no detectable imprint on patterns of community composition: observations from a natural experiment

Author:
KAARTINEN, RIIKKA; ROSLIN, TOMAS
Source:
Ecological entomology 2013 v.38 no.5 pp. 522-530
ISSN:

Subject:
case studies; community structure; foods; natural enemies; parasitism; phytophagous insects; population growth
Abstract:
... Indirect interactions mediated by natural enemies shared among herbivorous insects have recently attracted much interest. While many studies have predicted a high potential for apparent competition, only a few have rigorously tested predictions derived from the food web structure in terms of realised population and community dynamics. In this study, a quantified food web was used to identify pairs ...

Subject:
Curculio; dormancy; extinction; flight; fruits; genotype; insects; prediction; risk; sibling species; space and time; xerophytes
Abstract:
... Dormancy and dispersal are thought to be major adaptive mechanisms that enable short‐lived organisms to cope with environmental stochasticity. The few empirical investigations that have explored the relationship between these two strategies in disturbed environments have focused mainly on communities of annual desert plants and suggest that dispersal plays a negligible role, as compared with dorma ...

parasitism; food webs; Linepithema humile; Aphytis; Aonidiella aurantii; trees; mutualism; honeydew; Citrus; insects; lemons; California
Abstract:
... Protection mutualisms between ants and honeydew‐producing insects influence arthropod food webs by altering the behaviour, activity and local abundance of ants on plants. Ants often tend multiple species of honeydew‐producing insects; however, studies that examine such effects typically consider only pairwise mutualisms. This study investigates how multi‐species mutualisms between ants and honeyde ...

Subject:
Asphondylia; Borrichia; Iva; Torymus; galls; herbivores; host plants; islands; parasitism; parasitoids; Florida
Abstract:
... Associational resistance (AR) occurs when a plant species experiences less herbivory when growing in the presence of other plant species than when growing in monoculture. Densities of the gall midge Asphondylia borrichiae Rossi & Strong on the coastal plant Iva frutescens L. are depressed in the presence of a second coastal plant species, Borrichia frutescens (L.). Previous studies suggested that ...

Subject:
Coleoptera; Formicidae; bark; forests; indicator species; invasive species; nesting sites; sawing; tree mortality; California; San Bernardino National Forest
Abstract:
... A severe bark beetle outbreak caused very high levels of tree mortality in the San Bernardino National Forest in southern California in 2003. In 2009, the impact of the outbreak on the ant community was examined by pitfall‐trapping ants in 15 sites that saw high tree mortality (‘red’ sites) and 15 sites that suffered little or no tree mortality (‘green’ sites) during the outbreak. Ant species turn ...

6. Influence of extrafloral nectary phenology on ant–plant mutualistic networks in a neotropical savanna

Subject:
correlation; nectar secretion; nectaries; phenology; plant communities; savannas; temporal variation
Abstract:
... Temporal variation has been one remarkable feature of ecological interactions. In ant–plant mutualism, this variation is widely known, although little is understood about the mechanisms that shape these variations. This study tested whether or not the phenology of extrafloral nectaries (EFNs) influences the temporal variation of two properties of an ant–plant interaction network. The network under ...

Abstract:
... Utetes anastrephae (Viereck) and Doryctobracon areolatus (Szépligeti) are common, native, Neotropical braconid parasitoids of tephritid fruit flies that are sympatric and often found attacking the same host. The coexistence of the two species may be due in part to the longer ovipositor of D. areolatus that permits it to attack larvae in larger fruit than can U. anastrephae. This increases its pote ...

8. Larger clutches of chemically defended butterflies reduce egg mortality: evidence from Battus philenor

Abstract:
... Many toxic butterflies lay eggs in clusters and their eggs are aposematically coloured to warn predators. The pipevine swallowtail, Battus philenor (L.) (Papilionidae), is a specialist herbivore on plants in the genus Aristolochia, from which it sequesters toxic alkaloids (aristolochic acids, AAs). Eggs of this group of butterflies are laid singly or in clusters of different sizes, are aposematic ...

Abstract:
... Despite considerable research into the effects of leaf‐cutting ant nests, the potential occurrence of low‐nutrient soils at nest sites has hitherto gone undetected. Leaf litter cover and topsoil conditions (organic carbon, total nitrogen, soil acidity, cation exchange capacity) were assessed along transects running from nests of eight adult Atta cephalotes colonies into the understorey of Atlantic ...

Abstract:
... Preference–performance relationships are thought to be particularly important for sessile herbivores, such as leaf miners, whose choice of host plant is entirely determined by the ovipositing female. However, this relationship has seldom been examined between a non‐native herbivore and non‐native host plants. Leaf damage and oviposition patterns by the invasive horse‐chestnut leaf miner, Cameraria ...

Agaonidae; Ficus; figs; mutualism; parasitism; parasitoids; pollinators; trees
Abstract:
... Fig trees (Ficus) and their species‐specific pollinators (Agaonidae) represent a remarkable example of a coevolved mutualism. A number of non‐pollinating fig wasps (gallers and parasitoids, NPFW) are also an integral part of the mutualism, but have a negative impact on the reproductive success of the mutualists. Most NPFW belong to subfamilies only associated with figs and clearly have a long asso ...

Abstract:
... Tritrophic interactions among plants, herbivores and predators are expected to be influenced by the surrounding vegetation. Neighbouring plants can influence focal plant colonisation by herbivorous insects and the foraging behaviour of natural enemies, such as insectivorous birds. The aim of the experiment was to disentangle the interactive effects of neighbouring plants and avian predation on art ...

Subject:
Isoptera; biomass; nests; population dynamics; social insects
Abstract:
... Colony size is often attributed a key role in social insect population ecology. However, in nest‐building termites, colony size is a power function of nest volume, so that colonies of species with low scaling exponents tend to grow less as their nests are expanded. Thus, in such species, intercolonial differences in colony size may be less likely to develop, and changes in species total biomass ma ...
