Frugivorous animals may use morphological traits of food items such as size, hardness, shape, color and smell as cues that allow them to assess cost-benefit relationship of foraging activity. Fruit size is an important trait that influences feeding behavior of most frugivores, since there is a functional correlation between fruit size and frugivores ...

Os lepidópteros-praga, especialmente do gênero Spodoptera, apresentam elevado potencial de danos à produção agrícola, o que tem levado ao uso intensivo de inseticidas convencionais; entretanto, produtos naturais emergem como alternativas sustentáveis para o manejo desses organismos. Neste estudo, os efeitos de contato dos óleos extraídos de P.

The best of two worlds: ecology and evolution of ambophilous plants
ABSTRACT Ambophily, the mixed mode of wind and insect pollination is still poorly understood, even though it has been known to science for over 130 years. While its presence has been repeatedly inferred, experimental data remain regrettably rare. No specific suite of morphological or ecological characteristics has yet been identified for ambophilous ...
