Summary Plant hormones play important roles in regulating plant growth and defence by mediating developmental processes signalling networks involved responses to a wide range of parasitic mutualistic biotic interactions. Plants are known rapidly respond pathogen herbivore attack reconfiguring their metabolism reduce pathogen/herbivore food acquisition. This involves the production defensive secondary compounds, but also an alteration primary fuel energetic requirements direct defence....
Millions of years co-evolution between animals and their associated microbial communities have shaped diversified the nature relationship. Studies continue to reveal new layers complexity in host–microbe interactions, fate which depends on a variety different factors, ranging from neutral processes environmental factors local dynamics. Research is increasingly integrating ecosystem-based approaches, metagenomics mathematical modelling disentangle individual contribution ecological microbiome...
Plants respond to insect attack by releasing blends of volatile chemicals that attract their herbivores' specific natural enemies, while herbivores may carry endosymbiotic microorganisms directly improve herbivore survival after enemy attack. Here we demonstrate the two phenomena can be linked. fed upon pea aphids release volatiles parasitic wasps, and aphid facultative bacteria prevent development wasp larva thus markedly We show these endosymbionts also attenuate systemic plants attack,...
1. The decline in insect abundance and diversity observed many ecosystems is of major concern because the long‐term consequences for ecosystem function stability. 2. Species ecological communities are connected through interactions forming complex networks. Therefore, initial extinctions can cause further species losses co‐extinctions extinction cascades, where single lead to waves secondary extinctions. Such knock‐on effects multiply impact disturbances, thereby largely adding erosion...
Interactions between plants and herbivores are central in most ecosystems, but their strength is highly variable. The amount of variability within a system thought to influence aspects plant-herbivore biology, from ecological stability plant defense evolution. Our understanding what influences variability, however, limited by sparse data. We collected standardized surveys herbivory for 503 species at 790 sites across 116° latitude. With these data, we show that within-population increases...
Animals often engage in mutualistic associations with microorganisms that protect them from predation, parasitism or pathogen infection. Studies of these interactions insects have mostly focussed on the direct effects symbiont infection natural enemies without studying community-wide effects. Here, we explore effect a defensive population dynamics and species extinctions an experimental community composed three aphid their associated specialist parasitoids. We found introducing bacterial...
The genus Thrips comprises 296 species (ThripsWiki 2019) and is the largest of all Terebrantian genera. only other Thysanopteran genera comparable in size are phlaeothripids Haplothrips Liothrips. Species can be found flowers on leaves a wide variety plants from grasses to trees. Most them beneficial pollinators (Garcia-Fayos & Goldarazena 2008; Eliyahu et al. 2015), while others pests cause significant economic damage (Mound Marullo 1996). Some polyphagous widespread, rarely seen...
Abstract Many insect parasitoids are highly specialized and thus develop on only one or a few related host species, yet some hosts attacked by many different parasitoid species in nature. For this reason, they have been often used to examine the consequences of competitive interactions. Hosts represent limited resources for larval development competitor usually excludes all others. Although competition has debated studied over past several decades, understanding factors that allow...
Under predicted global climate change, species will be gradually exposed to warmer temperatures, and a more variable including intense frequent heatwaves. Increased climatic variability is expected have different effects on ecosystems than gradual warming. A key challenge predict the impact of change understand how temperature changes affect interactions. Herbivorous insects their natural enemies belong some largest groups terrestrial animals, thus they great functioning services these...
The genus Dendrothripoides was originally described by Bagnall (1923) from India and is currently represented five species (ThripsWiki 2020). innoxius (Karny) widely distributed in the Oriental Pacific regions; D. microchaetus Okajima Philippines Indonesian archipelago; nakaharai Reyes known only Philippines, poni Kudo Thailand, venustus Faure Rhodesia [Zimbabwe] South Africa (Faure 1941; 1977; Bournier 2000). Little about biology of these because collections often have samples with few...
Abstract Ecosystem engineering is a ubiquitous process where species influence the physical environment and thereby structure ecological communities. However, there has been little effort to synthesize or predict how ecosystem may impact stability of interaction networks. To assess current scientific understanding impacts via habitat forming, modification bioturbation on networks/food webs, we reviewed literature covering marine, freshwater terrestrial food plant‐pollinator networks theory....
Abstract Aim Elevational gradients are a useful approach to evaluate how environmental factors affect animal diversity. Decades of studies on the elevation‐diversity gradient have revealed that this varies greatly with taxa and geographic regions. One potential explanation for may be dependence relationship landscape features. We explore impact fragmentation, habitat diversity amount insect (alpha beta) abundance along elevational gradients. hypothesize will relate negatively elevation, but...
Plants are sessile organisms and, consequently, exposed to a plethora of stresses in their local habitat. As result, different populations species subject selection pressures leading adaptation conditions and intraspecific divergence. The annual brassicaceous plant Arabidopsis thaliana is an attractive model for ecologists evolutionary biologists due the availability large collection resequenced natural accessions. Accessions A. display one two life cycle strategies: summer winter annuals....
The browntail moth Euproctis chrysorrhoea is a highly polyphagous univoltine forest pest. Although its young larvae usually overwinter in diapause from early autumn to the beginning of spring, winter larval feeding has been reported when this species feeds on evergreen woody shrub strawberry tree Arbutus unedo. present study investigated life‐history traits four populations E. A. unedo , including phenology different life stages, activity and incidence. By modelling relationship between size...
