Abstract:
Pollinator studies in the endangered California sage scrub ecosystem have focused on spring insect assemblages, when most plant species bloom. Consequently, the insect assemblages using common fall-blooming sage scrub shrubs Lepidospartum squamatum, Ericameria pinifolia, and Baccharis pilularis remain undescribed. Our study aimed to: (1) document flower-visiting insect assemblages on fall-blooming shrubs, (2) assess the efficacy of three sampling techniques in inventorying insect assemblages, and (3) explore, using DNA metabarcoding, which plants are utilized and the extent to which surroundin

AbstractPrevious radiocarbon ages of detrital moss fragments in basal organic sediments of Lake Emma indicated that extensive deglaciation of the San Juan Mountains occurred prior to 14,900 yr B.P. (Carrara et al., 1984). Paleoecological analyses of insect and plant macrofossils from these basal sediments cast doubt on the reliability of the radiocarbon ages. Subsequent accelerator radiocarbon dates of insect fossils and wood fragments indicate an early Holocene age, rather than a late Pleistocene age, for the basal sediments of Lake Emma. These new radiocarbon ages suggest that by at least 10

Extreme global warming and environmental changes associated with the Toarcian (Lower Jurassic) Oceanic Anoxic Event (T-OAE, ~183 Mya) profoundly impacted marine organisms and terrestrial plants. Despite the exceptionally elevated abundances of fossil insects from strata of this age, only assemblages from Germany and Luxembourg have been studied in detail. Here, we focus on the insect assemblage found in strata recording the T-OAE at Alderton Hill, Gloucestershire, UK, where <15% of specimens have previously been described. We located all known fossil insects (n = 370) from Alderton Hill, an

Abstract:
ABSTRACT The paleoenvironmental resolving power of late CenozoicColeoptera fossils from arctic and subarctic sites is hindered by the fact that the fossil assemblages often differgreatly in taxonomic diversity and minimum number of individuals represented. In order to compare faunas of different age and from different sites, the fossil insect assemblages must first be normalized. One method of doing this is to group the fossils according to the ecological requirements of the taxa that they represent and then compare assemblages on the basis of the percentage of individual insects in each group

Agricultural land use causes habitats fragmentation and riparian vegetation removal, driving variability in the composition of aquatic insect assemblage in streams. We explored the effect of agriculture on the beta diversity of insect assemblages of Ephemeroptera, Plecoptera and Trichoptera (EPT) in Atlantic forest streams. We measured water physical and chemical variables and quantified the land cover of 10 stream catchments to determine the environmental integrity of the streams. The percentage of vegetation range was ∼6% to ∼47%, and agricultural land use range was ∼24% to ∼88%. We collecte

Evidence found in results of studies of latitudinal gradients of benthic macroinvertebrate diversity is variable. This study analysed how species and genus richness and the composition of caddisfly assemblages (Insecta: Trichoptera) vary in Argentinean mountain forest through a latitudinal gradient from 22 to 28°S. Qualitative and quantitative data from 20 stream sites were compared. Assemblage richness and composition were analysed by comparing linear regressions, rank–abundance (RA) curves and non-metric multidimensional scaling (nMDS). Taxonomic richness increased from high to low latitude.

ABSTRACT The paleoenvironmental message delivered by any fossil assemblage is nearly always filtered to some degree by taphonomic and preservational biases. This paper discusses some of the types of biases that affect the composition of fossil Coleoptera (beetles) assemblages. Eight samples from a single site in the northern Yukon provide the raw data for the analysis. They represent different types of host sediments — ranging from autochthonous peats to organic rich alluvial sands.

Tillage could significantly change the biodiversity in farmlands. As a prominent component of farmland ecology, crops play a key role in regulating biological communities. To explore the effects of tillage patterns and planting modes, including high-disturbance tillage practices and different plant compositions, on the abundance of soil insects, we tested the responses of soil insects to no-tillage (NT), ridge tillage (RT), and fall plow (FP) treatments with different planting modes. The results illustrated that planting modes significantly changed the distributions of ground-dwelling insect s

AbstractSaproxylic insect assemblages inhabiting dead wood in Canadian forests are highly diverse and variable but quite poorly understood. Adequate assessment of these assemblages poses significant challenges with respect to sampling, taxonomy, and analysis. Their assessment is nonetheless critical to attaining the broad goals of sustainable forest management because such species are disproportionately threatened elsewhere by the reductions in dead wood generally associated with commercial exploitation of northern forests. The composition of the saproxylic fauna is influenced by many factors,

Abstract:
The application of numerical techniques within palaeoentomology has been sporadic and of a largely simplistic nature. In particular, the assessment of faunal similarity has relied mainly upon subjective value judgements; similarly, the reconstruction of past climates using fossil Coleoptera has been undertaken with only a limited application of numerical methods. This thesis presents a computational approach to these problems. Although the intrinsic properties of palaeoentomological sample units impose limitations on the validity of a statistical analysis of faunal similarity, the use of such

Heather moorland is highly valued for its economic, cultural and biodiversity interest.  Recent declines in moorland extent are largely attributable to intense livestock grazing pressure and atmospheric nitrogen deposition.  Their combined influence leads to a replacement of <i>Calluna vulgaris</i> as the dominant plant by graminoids, especially <i>Molinia caerulea </i>or <i>Nardus stricta</i>.  Recent management has sought to reverse this process and restoration projects utilising either grazing control or more intensive mechanical methods have been initiated at a number of sites.  However th

Insects are well recognised as being the major contributor to global biodiversity, and for their critical involvement in many biotic interactions. Most of the insect diversity is found in tropical rainforests. However, these forests are threatened by high rates of clearing and the subsequent fragmentation of remaining habitat. The effects on biota, particularly insects, are poorly understood as are the mechanisms mediating faunal changes. Reforestation could potentially alleviate some of the deleterious effects of forest loss and fragmentation. However, because reforestation is a relatively ne

They reduce ant abundance and species richness, thus also changing ant assemblage structure. This is alarming, because almost 1300 species of plant species in the CFR are dispersed by certain indigenous ants, and thus there is concern for an indirect effect on indigenous plant assemblages. One of the most impacting ant species on seed dispersal is the invasive Argentine ant

Abstract:
Abstract Insect eggs are a small, but nutritive food source for parasitoid progeny. They are sedentary and unable to resist attacks of parasitoid wasps or to escape from them, and lack an immune system or other pervasive internal defence (Strand 1986). Thus, they are attacked by many species of small hymenopterous parasitoids, such as chalcidoids and proctotrupoids. Among insect eggs, those of Lepidoptera are frequently attacked by such parasitoids, probably because they are often exposed. Therefore, it is not surprising that a host species supports several egg parasitoid species. According to
