Pollen as an alternative food for Harmonia axyridis
TLDR
The exploitation of pollen and other plant foods at times when insect prey is scarce, may offer a further competitive advantage to the non-indigenous coccinellid H. axyridis over native European predatory lady beetles that share the same niche and are less capable of using pollen as an alternative food.

Development and reproduction of Adalia bipunctata (Coleoptera: Coccinellidae) on eggs of Ephestia kuehniella (Lepidoptera: Phycitidae) and pollen.
TLDR
Findings indicate that A. bipunctata is able to compensate for a suboptimal diet of animal prey by supplementary feeding on flower pollen, and concludes that pollinivory may be a crucial trait for both the rearing of this natural enemy and its use in biological control programmes. Expand
Lateglacial and Holocene fluvial dynamics in the Lower Scheldt basin (N-Belgium) and their impact on the presence, detection and preservation potential of the archaeological record
Abstract Several alluvial areas in the Lower Scheldt basin (LSB) have been subjected to geo-archaeological surveys and excavations in light of tidal restoration and nature development projects.Expand
Diet-dependent cannibalism in the omnivorous phytoseiid mite Amblydromalus limonicus
TLDR
The rate of cannibalism was dependent on the food source offered, but always resulted in reduced population growth rates and cannibalistic behavior should be taken into account when selecting food sources for mass rearing of A. limonicus or supporting its populations in the field. Expand
Selective woodland exploitation for charcoal production. A detailed analysis of charcoal kiln remains (ca. 1300–1900 AD) from Zoersel (northern Belgium)
A detailed study of charcoal burning activities has been made for the Zoersel forest (Northern Belgium) based on an inventory of charcoal kiln remains, the analyses of wood charcoal and other charredExpand
Long term change in chemical properties of preindustrial charcoal particles aged in forest and agricultural temperate soil
Abstract Black carbon (BC) plays an important role in terrestrial carbon storage. Nevertheless, the effect of cultivation on long term dynamics of BC in soil has been poorly addressed. To fill thisExpand
MIDDLE AND LATE HOLOCENE VEGETATION AND LANDSCAPE EVOLUTION OF THE SCHELDT ESTUARY. A PALYNOLOGICAL STUDY OF A PEAT DEPOSIT FROM DOEL (N-BELGIUM).
Local and regional environmental conditions for the south-eastern Scheldt estuary during the middle and late Holocene period have been reconstructed based on pollen analysis, loss-on-ignition andExpand
THE HOLOCENE HISTORY OF TAXUS BACCATA (YEW) IN BELGIUM AND NEIGHBOURING REGIONS
TLDR
The Holocene distribution and palaeo ecology of Taxus taccata are discussed in a broader northwest European context and an overview of the palaeobotanical finds from Belgium is given, supplemented with finds from neighbouring regions. Expand
Alternative foods for the multicoloured Asian lady beetle Harmonia axyridis (Coleoptera: Coccinellidae)
TLDR
Gut analysis demonstrated that, despite the continued presence of aphids, over 90% of all the adults collected contained pollen throughout the year, suggesting that in the field in the majority of cases pollinivory mainly only provided complementary nutrients for this coccinellid. Expand
Wood charcoal and seeds as indicators for animal husbandry in a wetland site during the late mesolithic–early neolithic transition period (Swifterbant culture, ca. 4600–4000 b.c.) in NW Belgium
Analysis of wood charcoal and seeds from ‘Doel sector M’, a Swifterbant site (ca. 4600–4000 b.c.) from NW Belgium, provides information on the environment, plant food subsistence, animal husbandryExpand
