Evaluation of counterattack efficiency against predators in Schizotetranychus brevisetosus using small glass beads and phytoseiid eggs

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
The web‐nesting spider mite Schizotetranychus brevisetosus Ehara attacks predators outside the nest, but the effectiveness of this behaviour is unknown. Spreading predator‐mimicking glass beads over the web induced intense patrolling behaviour in females, which even captured and attacked beads.

Past research and future directions in understanding how birds use their sense of smell

open access: yesIbis, EarlyView.
Our understanding of the functional importance of olfaction to birds has improved over the past 60 years, largely as the result of experimental studies testing how birds use their sense of smell in different contexts. As it is impossible to measure directly which odours birds can detect, we rely on measuring behavioural responses to scent cues or ...

Field evaluation of Streptomyces rubrogriseus HDZ-9-47 for biocontrol of Meloidogyne incognita on tomato

open access: yesJournal of Integrative Agriculture, 2017
Streptomyces rubrogriseus HDZ-9-47, isolated from eggs of Meloidogyne spp., was evaluated as a potential biocontrol agent of Meloidogyne incognita under in vitro and protective field.

Nest clustering correlates with breeding phenology rather than female relatedness in Red‐breasted Mergansers (Mergus serrator)

open access: yesIbis, EarlyView.
Fine‐scale spatial and temporal genetic structuring of nests is possible in colonial birds that return to breed at their natal sites, and notably in waterfowl for which females are more philopatric than males. We genotyped female Red‐breasted Mergansers Mergus serrator breeding colonially on a coastal archipelago in eastern New Brunswick, Canada ...

Dinámica temporal en la relación entre el isópodo parásito Aporobopyrus curtatus (Crustacea: Isopoda: Bopyridae) y el cangrejo anomuro Petrolisthes armatus (Crustacea: Decapoda: Porcellanidae) en el sur de Brasil Temporal dynamic of the relationship between the parasitic isopod Aporobopyrus curtatus (Crustacea: Isopoda: Bopyridae) and the anomuran crab Petrolisthes armatus (Crustacea: Decapoda: Porcellanidae) in southern Brazil

open access: yesLatin American Journal of Aquatic Research, 2010
The prevalence of the parasite Aporobopyrus curtatus in Petrolisthes armatus from southern Brazil was determined, and the effect the parasite had on host reproduction was evaluated. Of all 775 crabs sampled in Araçá region from March 2005 to July 2006, 3.

Unexpected diversity of alternative reproductive tactics revealed in Water Rails (Rallus aquaticus)

open access: yesIbis, EarlyView.
Monogamy in birds was long considered a general mating system until molecular studies provided evidence of alternative reproductive strategies (ARS), which are now assumed to be present in ~90% of bird species. These ARS or tactics (ART), as we consider them in this study, include extra‐pair copulation, which can lead to extra‐pair paternity or extra ...
