insect communities,   etc   ; endosymbionts; insects; natural enemies; parasites; predators; trophic levels;     Show all 7 Subjects
Abstract:
... Defensive endosymbionts are now understood to be widespread among insects, targeting many different threats, including predators, parasites and disease. The effects on natural enemies can be significant, resulting in dramatic changes in the outcome of interactions between insects and their attackers. Evidence is now emerging from laboratory and field work that defensive symbionts can have importan ...

Abstract:
... Floodplains are inhabited by diverse and abundant ground beetle assemblages that are adapted to the frequently changing habitat conditions. While there have been many studies on the composition of riparian ground beetle communities in individual floodplains, the general patterns responsible for their composition remained obscure. We used data on 352 ground beetle samples taken at 224 sites along r ...

Abstract:
... Initial colonists of empty habitats tend to differ from those arriving later in terms of species identity and traits. We evaluated the dynamics of the functional attributes in aquatic insect communities during a colonization experiment under natural conditions. We tested whether the late stages of colonization show higher functional richness, diversity and specialization than early successional st ...

Abstract:
... Although elevational gradients of biodiversity have long been the topic of scientific research, information on patterns of, and processes that shape insect community structure across elevation is still lacking. Addressing this gap requires the use of both taxonomic and functional approaches when studying diversity across elevational gradients. In this study, we examined taxonomic and functional al ...

Abstract:
... Despite the critical role of pulsed resources on the dynamics and conservation of several forest-dwelling species, the transition between the period when the effects of a thinning-induced resource pulse are maximal and the period when only residual effects remain has yet to be documented in forest habitats. In this study, we investigated the occurrence of a transition period after a woody necromas ...

Abstract:
... Ecological networks are useful for characterizing interspecific associations and predicting the resilience of ecological communities. We evaluated how such networks vary with the size, spatial distribution, and timing of availability of resources, with a focus on beetle-macrofungal associations. We used 2 y of field experiments to construct ecological networks based on manipulated sporocarp baits ...

Abstract:
... Global light pollution threatens to disturb numerous wildlife species, but impacts of artificial light will likely vary among species within a community. Thus, artificial lights may change the environment in such a way as to create winners and losers as some species benefit while others do not. Insectivorous bats are nocturnal and a good model to test for differential effects of light pollution on ...

Abstract:
... Biodiversity research in tropical ecosystems—popularized as the most biodiverse habitats on Earth—often neglects invertebrates, yet invertebrates represent the bulk of local species richness. Insect communities in particular remain strongly impeded by both Linnaean and Wallacean shortfalls, and identifying species often remains a formidable challenge inhibiting the use of these organisms as indica ...

Abstract:
... BACKGROUND: Genetic variation in plants alters insect abundance and community structure in the field; however, little is known about the importance of a single gene among diverse plant genotypes. In this context, Arabidopsis trichomes provide an excellent system to discern the roles of natural variation and a key gene, GLABRA1, in shaping insect communities. In this study, we transplanted two inde ...

Morphology can characterise the morphometric niche of species and can be represented as body shape points within a morphometric universe. This information can be to calculate the morphometric diversity of communities through hypervolume ...

Abstract:
... 1. It is hypothesised that ecological restoration in grasslands can induce an alternative stable state shift in vegetation. The change in vegetation influences insect community assemblages and allows for greater functional redundancy in pollination and refuge for native insect species. 2. Insect community assemblages at eight coastal California grassland sites were evaluated. Half of these sites h ...

However, less is known about the impact of urbanization on insects in headwater streams within smaller cities that have significant upstream portions outside of urban land use. We collected insects monthly from April to Sep ...

Abstract:
... 1. Variation in spring phenology – like tree budburst – affects the structure of insect communities, but impacts of autumn phenology have been neglected. Many plant species have recently delayed their autumn phenology, and the timing of leaf senescence may be important for herbivorous insects. 2. This study explored how an insect herbivore community associated with Quercus robur is influenced by v ...

Abstract:
... Half of Borneo's forest has been logged and oil palm plantations have replaced millions of hectares of forest since the 1970's. While this extensive land-use change has been shown to reduce species richness across landscapes, there is limited current knowledge on how deforestation affects the spatial arrangement of ecological communities. Identifying responses of beta-diversity to land-use change ...

Abstract:
... Changes to the fire regime in boreal Alaska are shifting the ratio of coniferous to deciduous dominance on the landscape. The increase in aspen and birch may have important effects on predatory hymenopteran assemblages by providing a source of extrafloral nectar and increasing prey availability. Furthermore, fire-induced changes in successional age alter habitat structure and microclimate in ways ...
