Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants typically interact with multiple, co‐occurring symbionts, including arbuscular mycorrhizal (AM) fungi which can form networks, connecting neighbouring plants. A characteristic aspect of the mycorrhizal symbiosis is the bidirectional exchange of nutrients between ...

European Journal of Entomology, 2005 The research on pre-diapause feeding of C. septempunctata L. adults was carried out from 1998 to 2002 in the Tiber Valley, in the Botanical Garden of Perugia University, and in the Sibillini Mountains National Park (Central Italy). The species reproduces

, 2013 Aphids are among the most severe invertebrate pests of crops and cause high economic losses. The control of aphids by natural enemies is an essential ecosystem service with high relevance to management strategies applied in agricultural plant production ...

Quantifying phenotypic plasticity: A call for consistency
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract The interest of evolutionary, functional and applied ecologists in the study of phenotypic plasticity has grown considerably in recent decades. From being considered irrelevant in the mid‐20th century, phenotypic plasticity is now considered ubiquitous and essential for

Physiological determinants of male mating performance in aphids (Hemiptera: Aphididae)
European Journal of Entomology, 2005 When investigating sexual strategies of aphids, it is necessary to set up multiple replicates to compensate for the small number of eggs laid per female.

The role of developmental plasticity in eco‐phenotypic population dynamics
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Individual variation in development can strongly impact population density via its impact on demography. When this variation in development is caused by developmental plasticity, the resulting effects on population density are characterised as ‘eco‐phenotypic dynamics ...

Journal of Applied Ecology, EarlyView.A framework for the support of pollinators in urban areas is developed here, based on five pillars: nesting, flower resources, artificial support, management and society acceptance, with additional key elements from science and society. Society should incorporate strategies for pollinators as in this framework by means of co‐planning with stakeholders,

Interactive Image-Based Aphid Counting in Yellow Water Traps under Stirring Actions [PDF]
arXivThe current vision-based aphid counting methods in water traps suffer from undercounts caused by occlusions and low visibility arising from dense aggregation of insects and other objects. To address this problem, we propose a novel aphid counting method through interactive stirring actions.

Parasitoids as vectors of facultative bacterial endosymbionts in aphids
Biology Letters, 2012 Heritable bacterial endosymbionts play an important role in aphid ecology. Sequence-based evidence suggests that facultative symbionts such as Hamiltonella defensa or Regiella insecticola also undergo horizontal transmission.
