Evaluation of responses of different ant species (Formicidae) to the scavenger deterrent factor associated with the entomopathogenic nematode-bacterium complex

open access: yesEuropean Journal of Entomology, 2018
According to previous observations, it was hypothesized that the feeding behavior of some ant species would be deterred by a scavenger deterrent factor (SDF), whereas for other species it would not.

Testing the size‐grain hypothesis in a generalist predator: The case of an ant species in the Brazilian savannah

open access: yesJournal of Zoology, EarlyView.
In our recent study, we examined whether ants in the Brazilian Cerrado follow the “grain‐size hypothesis,” which proposes that larger ants should have proportionally longer legs to move efficiently across different environments. We used Ectatomma permagnum, a common predatory ant in the Cerrado, measuring hundreds of individuals collected from various ...

Not simply red: Colouration of red wood ant Formica rufa (Hymenoptera: Formicidae) is polymorphic, modular and size-dependent

open access: yesEuropean Journal of Entomology, 2017
Insects produce pigment and structural colours mainly for camouflage, signaling, physical protection or temperature regulation, and colour patterns can provide information about individual quality.

Trait‐based recovery of insect functional diversity following pine removal in a shrubland biodiversity hotspot

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction A primary goal of habitat restoration is the return of both taxonomic and functional diversity to support ecosystem resilience and functioning. This study assessed how insect functional biodiversity (focusing on beetles [Coleoptera] and ants [Formicidae]) responds to invasive pine (Pinus spp.) removal, in a Mediterranean‐type ...

Indirect effects of ant predation (Hymenoptera: Formicidae) on bilberry Vaccinium myrtillus

open access: yesEuropean Journal of Entomology, 2005
Bilberry (Vaccinium myrtillus L.) is one of the dominant plants of the Fennoscandian boreal coniferous forest and constitutes a major food source for many insect herbivores.

Restoration tools and strategies for afforested Mediterranean coastal grasslands: is eucalypt removal alone enough to kickstart ecosystem recovery?

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Afforestation with non‐native trees has profoundly altered coastal dune grasslands worldwide, creating persistent ecological legacies that constrain ecosystem recovery. Objectives We evaluated the cost‐effectiveness of two restoration approaches, distinguished by their respective demands for resource investment: Moderately ...

Cost to the cavity-nest ant Temnothorax crassispinus (Hymenoptera: Formicidae) of overwintering aboveground

open access: yesEuropean Journal of Entomology, 2013
Most species of ants inhabiting the temperate zone overwinter underground, whereas those of the genus Temnothorax remain in nests aboveground. I studied the cost of aboveground overwintering. Workers of Temnothorax crassispinus survived in higher numbers
