Integrating ecological feedbacks across scales and levels of organization
Ecography, EarlyView.In ecosystems, species interact in various ways with other species, and with their local environment. In addition, ecosystems are coupled in space by diverse types of flows. From these links connecting different ecological entities can emerge circular pathways of indirect effects: feedback loops.

Leaf cutting-ants: Control methods and sustainability
, 2022 The fungus-growing ants belong to the genus Atta and Acromyrmex and individuals are causing serious damage to various types of plantations due to the habit of cutting leaves and shoots of economic importance for use in cultivating the garden symbiotic fungus colonies, causing serious damage. The ants attack is harmful at any stage of the cycle, but the

Ecological Entomology, EarlyView.The height at which epiphytic bromeliads are found affects the invertebrate community composition within them. The size of epiphytic bromeliads is positively correlated with species richness of both aquatic and terrestrial invertebrates. Whether bromeliads were found in primary or secondary forest did not have a significant effect on the community of ...

Ecological Entomology, EarlyView.Extrafloral nectar mediates interactions among plants, ants and herbivores; its contingency on damage amount and within‐plant uniformity is poorly understood. Here, we explore these factors in wild cotton (Gossypium hirsutum). Herbivory amount drove increases in extrafloral nectar induction per nectary, whereas within‐plant variability in damage ...

An Easy Method to Sample Headspace Pheromones in the Field
Ethology, EarlyView.Females of the orb‐web spider Argiope bruennichi produces a pheromone to attract males for mating. Most of our knowledge about the pheromone and its strategical use by the females is known from the laboratory. While we have confidence in the validity of these results, we wanted to make sure and measure pheromones in the field.

Insect Conservation and Diversity, EarlyView.Diverse Saturniidae moth communities are found in naturally recovering tropical forests in Ecuador. Community composition showed a gradual turnover with strongest differences between old‐growth forest and active agriculture, but only weak differences in taxonomic, phylogenetic and functional diversity. While our results suggest that Saturniidae are not
