Absence of nectar resource partitioning in a community of parasitoid wasps [PDF]

open access: yes, 2015
Parasitoid wasps occur in diverse communities, with the adults of most species sourcing carbohydrates from nectar or honeydew. However, the role of niche partitioning of nectar resources in maintaining diverse communities of parasitoid Hymenoptera is ...

Variation in pollen limitation among reproductive modules points to likely resource reallocation in the alpine plant Veratrum grandiflorum

open access: yesNordic Journal of Botany, EarlyView.
Pollen limitation, a decrease in seed production due to insufficient pollen receipt, may influence plant demography and the evolution of sexual systems. Its empirical estimation of pollen supplementation of some of the flowers on an individual is well known to be prone to overestimation due to potential resource reallocation among the individual's ...

Learning is involved in the response of parasitic wasps Aphidius ervi (Haliday) (Hymenoptera: Braconidae) to volatiles from a broad bean plant, Vicia faba (Fabaceae), infested by aphids Acyrthosiphon pisum (Harris) (Homoptera: Aphididae) [PDF]

open access: yes, 2009
It has been reported that volatiles from broad bean plants, Vicia faba (cv. ‘the Sutton’) infested by the pea aphid, Acyrthosiphon pisum, attract a specialist parasitoid Aphidius ervi, collected from populations in England, Italy and Bulgaria, which had ...

Community composition mediates interannual shifts in pollinators' roles within networks

open access: yesNordic Journal of Botany, EarlyView.
Plant–pollinator networks are complex structures that describe interactions between plants and pollinators within ecological communities. Understanding how these networks are organized is crucial for the preservation of populations, communities, and ecosystem services, because network structure is linked to the function and resilience of communities ...

Figs and fig wasps.

open access: yes, 2005
What are figs and fig wasps? Figs are plants in the genus Ficus, which have a unique closed inflorescence called a syconium, typically containing hundreds of flowers. We eat the ripe syconia of one species, F.

The hunt for Scabiosa trenta Hacq: how the pursuit of a phantom ignited a passion for botany and mountaineering

open access: yesNordic Journal of Botany, EarlyView.
Scabiosa trenta Hacq. was first described in 1782 by Balthasar Hacquet, with its specific epithet referring to the Trenta Valley in Slovenia. Since then, S. trenta has been the focus of numerous mountaineering and botanical expeditions, particularly by the alpinist Julius Kugy during the Golden Age of Alpinism, a period in the second half of 19th ...

Examining the multi‐disciplinary origins of biophobia towards threatening and non‐threatening wildlife in a highly urbanised city in China

open access: yesPeople and Nature, EarlyView.
Abstract Urbanisation is reshaping how people experience wildlife, reducing our shared spaces with local biodiversity. Fewer opportunities for human–wildlife interactions weaken our emotional attachments to nature and precipitate a loss of species knowledge and familiarity.

The shared benefits of fallen fruits: A novel mechanism stabilizing a nursery pollination mutualism between Sambucus and kateretid beetles

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.
