Reduced fertilization regimes could boost biocontrol service without reducing crop yield

Insect Science, EarlyView.
Fertilization level influences pest control effectiveness in tomato crops. High fertilization increases plant growth and aphid density but reduces the performance of the parasitoid Aphidius ervi. In contrast, the predator Adalia bipunctata maintains consistent aphid suppression regardless of fertilization regime.

Do aphid endosymbiotic bacteria influence parasitoid searching behaviour through changes in aphid honeydew production?

Ecological Entomology, EarlyView.
Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.

Assimetrias na harmonia vocálica em português do Brasil

Cadernos de Estudos Lingüísticos, 2014
É comum, em processos de harmonia vocálica, que a vogal /a/ não se comporte como um gatilho. Este é o caso, por exemplo, do iorubá (cf. Archangeli e Pulleyblank 1989).

Product Positioning and Incentives to Innovate

Journal of Economics &Management Strategy, EarlyView.
ABSTRACT This paper shows that product positioning affects the incentives to invest in process innovation. The result is found using a model of price competition with three firms under horizontal product differentiation—and then extended to a more general Bertrand triopoly.

A música dos números primos: a história de um problema não resolvido da matemática

Boletim GEPEM, 2008
Este livro propõe uma viagem no mundo dos números primos desde a Grécia antiga até os dias atuais. O ponto alto é a hipótese levantada por Riemann de que era possível haver harmonia entre os números primos semelhante a uma harmonia musical.

Analysing the Ecological Requirements of the Australian Tortoise Beetle Trachymela sloanei (Blackburn, 1897) (Coleoptera: Chrysomelidae) to Determine the Prospects for Its Invasion Process

Journal of Applied Entomology, EarlyView.
ABSTRACT Invasive species pose a serious threat to biodiversity and result in significant economic costs. Although much effort is devoted to understanding invasive processes, some aspects are poorly understood, such as the early stages of invasions and the reasons for invasion failure.
