Studies related to ants found in hospital environments have aroused interest in their role as mechanical vectors of pathogenic microorganisms. The objective of the current research was to determine the species composition and bacterial contamination of ant species found in a public hospital in the eastern Amazonian region. Ants were captured using ...

Tato práce se soustředí na vývoj prototypu pro amatérské i profesní chovatele mravenců. Konkrétně jde o inkubační a hibernační zařízení, které sníží počet ztrát královen mravenců při chovu a prodlouží jim života schopnost. Tento prototyp je realizován za pomoci Peltierova článku a mikrokontroleru pro řízení a zobrazování teploty a vlhkosti. V práci...

En tant que processus technique, la « robotique bio-inspirée » vise à la création d’un artefact à partir de fonctions identifiées dans le vivant. Les chercheurs et chercheuses de l’Institut des sciences du mouvement de Marseille tentent d’en reproduire deux principales : la navigation sans GPS (Global Positioning System) et le repérage dans l’espac...

Ant venoms have recently attracted increased attention due to their chemical complexity, novel molecular frameworks, and diverse biological activities. The heterodimeric peptide ∆-myrtoxin-Mp1a (Mp1a) from the venom of the Australian jack jumper ant, Myrmecia pilosula , exhibits antimicrobial, membrane-disrupting, and pain-inducing activities. In t...

The inappropriate or excessive use of antimicrobial agents caused an emerging public health problem due to the resulting resistance developed by microbes. Therefore, there is an urgent need to develop effective antimicrobial strategies relying on natural agents with different mechanisms of action. Nature has been known to offer many bioactive compo...

Symbiotic microorganisms can have a profound impact on the host physiology and behavior, and novel relationships between symbionts and their hosts are continually discovered. A colony of social ants consists of various castes that exhibit distinct lifestyles and is, thus, a unique model for investigating how symbionts may be involved in host eusoci...

Stictococcus vayssierei is a major pest of root and tuber crops in central Africa. However, data on its ecology are lacking. Here we provide an updated estimate of its distribution with the aim of facilitating the sustainable control of its populations. Surveys conducted in nine countries encompassing 13 ecological regions around the Congo basin sh...

ABSTRACT Four deutonymphs of bulb mites (hypopus) from Rhizoglyphus echinopus (Fumouze & Robin) (Acari: Acaridae) were found attached to the head of Atta sexdens in Rio de Janeiro, Brazil. This mite species is commonly associated with ornamental plants and trees with bulbs, corms and tubers. The results of this study provided an insight into the ph...

Abstract: Pheidole is a genus with wide geographical distribution and diversity, especially in the leaf litter of neotropical forests, where nests are found at the soil-litter interface, in the soil and vegetation, among leaves, seeds, and twigs. Despite the availability of twigs and Pheidole species diversity in the leaf litter, most of this resou...

Despite the environmental stresses that mangrove forests experience – including fluctuating salinity, low soil oxygen and buffeting by waves – they can be highly productive. Facilitation, defined here as the benefits to an organism by the minimisation by neighbouring organisms of biotic or physical stress, may help explain this. Theory suggests tha...
