Tachinidae (Diptera) as Floral Visitors and Pollinators in Natural and Managed Systems

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We review the roles of bristle flies (Tachinidae) as pollinators in natural and managed systems. We find that most tachinid genera visit flowers and that floral‐adapted mouthparts have evolved repeatedly many times in the family. We review patterns of floral specificity and assess the efficacy of tachinids as pollinators with case studies.

Parasitic wasp‐associated polydnavirus and venom affect arthropod community assembly on wild cabbage via the caterpillar host

open access: yesEcological Entomology, EarlyView.
Cotesia glomerata polydnavirus and venom, either alone or in combination, affect colonisation by members of the arthropod community in a natural field setting. Plants damaged by P. brassicae injected with both polydnavirus and venom were colonised more often by Mamestra brassicae caterpillars, Myzus persicae aphids and aphid parasitoids compared to ...

Fungal infection affects sexual signalling and mate choice in the sugarcane borer

open access: yesEcological Entomology, EarlyView.
Fungus‐infected Diatraea saccharalis females exhibit enhanced attractiveness to males in wind tunnel assays. Fungal infection alters the pheromone profile of females, increasing the relative abundance of Z9‐16: Ald, a minor but behaviourally active component of the species' sex pheromone blend.

Climatic, biogeographic and ecological factors influence the spatial patterns of odd‐ and even‐year dominance in biennial European butterflies and burnet moths

open access: yesEcological Entomology, EarlyView.
250,000 observations of 7 annual, 11 biennial and 4 flexible lepidoptera species in the Alps and over 150,000 observations of 5 biennial species from Scandinavia were analysed. Maps show distinct patterns of different species that fly predominantly in odd or even years in the researched areas.

Selective feeding and niche differentiation in adult boreal Odonata revealed by DNA metabarcoding

open access: yesEcological Entomology, EarlyView.
COI metabarcoding of faecal pellets from three sympatric Odonata species in boreal Swedish wetlands revealed Diptera‐dominated diets, with mosquitoes only a minor component despite high availability. The larger hawker Libellula quadrimaculata showed greater dietary variance than the smaller damselflies, indicating size‐ and foraging strategy‐dependent ...

Breaking the ice: multiple origins of ice‐binding/antifreeze proteins

open access: yesThe FEBS Journal, EarlyView.
Ice‐binding proteins (IBPs) evolved independently in many organisms during Cenozoic cooling and glaciation. In flounders, α‐helical IBPs evolved from an antiviral protein, while similar IBPs arose independently from different progenitors in three other fish lineages.

Dietary selectivity mediates niche overlap and interspecific competition in a reedbed warbler community in southern Europe

open access: yesIbis, EarlyView.
Sympatric species are expected to use resources differently along one or more ecological dimensions. This can be complex when there is partial separation along multiple dimensions, such as where bird species exhibit similarities in habitat use and diet.

Not all crickets are equal: selective shrike predation highlights the conservation value of diverse arthropod communities to grassland birds

open access: yesIbis, EarlyView.
Understanding dietary preferences and prey selection is pivotal for interpreting the ecology and conservation needs of threatened species. We investigated the diet composition and prey selection of the Red‐backed Shrike Lanius collurio in a montane grassland of the central Italian Apennines, with special regard to sex‐related differences and the ...

Seasonal shifts in network structure and species roles in a tropical island plant–flower visitor community Cambios estacionales en la estructura de la red de interacciones entre plantas y visitantes florales y en los roles de las especies en una comunidad insular tropical

open access: yesInsect Conservation and Diversity, EarlyView.
Constant visitation rates across the flowering season masked major shifts in plant and flower visitor interaction structure, specialization, species roles and trait‐driven patterns shaping interaction intensity. Plants and flower visitors changed ecological roles over time, with native flower visitors playing key roles in maintaining network cohesion ...
