Host-derived organic acids enable gut colonization of the honey bee symbiont Snodgrassella alvi

Diverse bacteria can colonize the animal gut using dietary nutrients or by engaging in microbial crossfeeding interactions. Less is known about the role of host-derived nutrients in enabling gut bacterial colonization. Here we examined metabolic interactio ...

Biohybrid Superorganisms—On the Design of a Robotic System for Thermal Interactions With Honeybee Colonies

Francesco Mondada, Robert Matthew Mills, Rafael Botner Barmak, Raphael Cherfan

Social insects, such as ants, termites, and honeybees, have evolved sophisticated societies where collaboration and division of labor enhance survival of the whole colony, and are thus considered “superorganisms”. Historically, studying behaviors involving ...

A robotic honeycomb for interaction with a honeybee colony

Francesco Mondada, Robert Matthew Mills, Rafael Botner Barmak

Robotic technologies have shown the capability to interact with living organisms and even to form integrated mixed societies composed of living and artificial agents. Biocompatible robots, incorporating sensing and actuation capable of generating and respo ...

Imidacloprid induces adverse effects on fish early life stages that are more severe in Japanese medaka (Oryzias latipes) than in zebrafish (Danio rerio)

Kristin Schirmer, Juliane Hollender

Neonicotinoids are widely used insecticides that have frequently been found in freshwater with concentrations ranging from ng to mu g/L. It is known that these compounds impact non-target invertebrates, such as bees and gammaridae, in terms of toxicity and ...

Quantifying the effects of land use and climate on Holocene vegetation in Europe

Jed Oliver Kaplan

Early agriculture can be detected in palaeovegetation records, but quantification of the relative importance of climate and land use in influencing regional vegetation composition since the onset of agriculture is a topic that is rarely addressed. We prese ...

Automated computer-based detection of encounter behaviours in groups of honeybees

Alessandro Crespi, Laurent Keller

Honeybees form societies in which thousands of members integrate their behaviours to act as a single functional unit. We have little knowledge on how the collaborative features are regulated by workers' activities because we lack methods that enable collec ...

Uncovering Latent Behaviors in Ant Colonies

Patrick Thiran, Matthias Grossglauser, Laurent Keller, Mohamed Kafsi, Raphaël Braunschweig

Many biological systems exhibit collective behaviors that strengthen their adaptability to their environment, compared to more solitary species. Describing these behaviors is challenging yet necessary in order to understand these biological systems. We pro ...

Benefits and limitations of using Fe(III)-EDDS for the treatment of highly contaminated water at near-neutral pH

César Pulgarin, Stefanos Papoutsakis

This study evaluates the use of the Fe(III)-EDDS complexing agent as an alternative to conventional acidic pH photo-Fenton for the treatment of the pesticide imidacloprid in natural water. The main objective is to estimate whether Fe(III)-EDDS is a viable ...

The Insecticide Imidacloprid Causes Mortality of the Freshwater Amphipod Gammarus pulex by Interfering with Feeding Behavior

Kristin Schirmer

If an organism does not feed, it dies of starvation. Even though some insecticides which are used to control pests in agriculture can interfere with feeding behavior of insects and other invertebrates, the link from chemical exposure via affected feeding a ...

Deposition and residues of azoxystrobin and imidacloprid on greenhouse lettuce with implications for human consumption

Anna Kounina Massé

Lettuce greenhouse experiments were carried out from March to June 2011 in order to analyze how pesticides behave from the time of application until their intake via human consumption taking into account the primary distribution of pesticides, field dissip ...
