Predation of Bradysia sp. (Diptera: Sciaridae), Liriomyza trifolii (Diptera: Agromyzidae) and Bemisia tabaci (Hemiptera: Aleyrodidae) by Coenosia attenuata (Diptera: Muscidae) in greenhouse crops

open access: yesEuropean Journal of Entomology, 2009
We studied the predation behaviour of the "hunter fly" (Coenosia attenuata Stein) in the laboratory and greenhouse. In the laboratory, which was conducted at 25°C at 60-80% RH, with a 16L : 8D photoperiod, we examined the functional response of this ...

Dopamine inactivation efficacy related to functional DAT1 and COMT variants influences motor response evaluation [PDF]

open access: yes, 2012
BACKGROUND: Dopamine plays an important role in orienting, response anticipation and movement evaluation. Thus, we examined the influence of functional variants related to dopamine inactivation in the dopamine transporter (DAT1) and catechol-O ...

The foraging behaviour of granivorous birds: a mechanistic perspective. [PDF]

open access: yes
1. The functional response, i.e. the feeding rate as a function of prey density, links resource availability to population level demographic rates. The functional response is often central to behavioural-based population models that predict the effect ...

Functional Response and Intraspecific Competition of Three Ladybird Species Feeding on Aphids on Goji Berry Plants in Laboratory and Semi-Field Conditions

open access: yesInsects, 2023
The aphid, Aphis gossypii Glover, is identified as a significant pest that causes severe damage to goji berries in China. To analyze the ladybird consumption of aphids, the functional responses of three ladybird species, Harmonia axyridis, Coccinella ...

Clustering dichotomously scored items through functional k-means algorithm

open access: yes, 2016
In the educational field, it is common to analyze the probability of a correct response to a test item as a continuous function of the item parameters and the subject ability. This relation is given by the item response function.

Local linear regression for functional predictor and scalar response [PDF]

open access: yes, 2007
The aim of this work is to introduce a new nonparametric regression technique in the context of functional covariate and scalar response. We propose a local linear regression estimator and study its asymptotic behaviour.

Personality, predation and group size: unravelling behavioural drivers of lionfish (Pterois volitans) invasion success

open access: yesRoyal Society Open Science
Global biodiversity is in rapid decline, with invasive alien species playing a major role. Predicting which is most damaging and under what conditions is key to proactive management.
