Agricultural and apicultural practices expose honeybees to a range of pesticides that have the potential negatively affect their physiology, neurobiology, behavior. Accumulating evidence suggests these effects extend honeybee gut microbiome, which serves important functions for health. Here we test thiacloprid, acetamiprid, oxalic acid on microbiota honeybees, first in direct vitro inhibition assays secondly an vivo caged bee experiment if exposure leads community changes. We found...
Background/Objectives: Many tropical diseases such as malaria, Chagas, human African Trypanosomiasis, and Lymphatic filariasis coexist in endemic countries, affecting more than 1 billion people worldwide, are recognised major global vector-borne diseases. Tackling this disease requires an accurate diagnosis that is sensitive, specific, rapid. This study aimed to describe validate a new highly sensitive specific multiple-analysis system can effectively detect numerous etiological agents...
Social insects maximize resource acquisition and allocation through division of labor associations with microbial symbionts. Colonies divide among castes subcastes, where the plasticity caste roles decreases in clades higher social grades. Recent studies indicate that specific may also foster distinct gut microbiomes, suggesting synergies between symbiosis. The organization a colony potentially partitions evolutionary persistent partners to optimize symbioses complement labor. However,...
Mutualistic coevolution can be mediated by vertical transmission of symbionts between host generations. Termites complex gut bacterial communities with evolutionary histories indicative mixed-mode transmission. Here, we document that strains is congruent across parent to offspring colonies in four pedigrees the fungus-farming termite Macrotermes natalensis. We show 44% colony microbiome, including more than 80 genera and pedigree-specific strains, are consistently inherited. go on...
A multitude of factors affect the assemblies complex microbial communities associated with animal hosts, implications for community flexibility, resilience, and long-term stability; however, their relative effects have rarely been deduced. Here, we use a tractable lab model to quantify combined parental transmission (egg case microbiome present/reduced), gut inocula (cockroach versus termite provisioned), varying diets (matched or unmatched inoculum source) on microbiota structure hatchlings...
Microbiome assembly critically impacts the ability of hosts to access beneficial symbiont functions. Fungus-farming termites have co-evolved with a fungal cultivar as primary food source and complex gut microbiomes, which collectively perform complementary degradation plant biomass. A large subset bacterial community residing within termite guts are inherited (vertically transmitted) from parental colonies, while is, in most species, acquired environment (horizontally transmitted). It has...
Abstract Background Monoculture farming poses significant disease challenges, but fungus-farming termites are able to successfully keep their monoculture crop free from contamination by other fungi. It has been hypothesised that obligate gut passage of all plant substrate used manure the fungal symbiont is key accomplish this. Here we refute this hypothesis in termite species Macrotermes bellicosus . Results We first ITS amplicon sequencing show foraged on workers harbour diverse...
Wild chimpanzee populations in West Africa (Pan troglodytes verus) have dramatically decreased as a direct consequence of anthropogenic activities and infectious diseases. Little information is currently available on the epidemiology, pathogenic significance, zoonotic potential protist species wild chimpanzees. This study investigates occurrence genetic diversity intestinal blood protists well filariae faecal samples (n = 234) from chimpanzees Dindefelo Community Nature Reserve, Senegal....
Haemosporidians are among the most common parasites of birds and often negatively impact host fitness. A multitude biotic abiotic factors influence these associations, but magnitude can differ by spatial scales (i.e., local, regional global). Consequently, to better understand global drivers avian-haemosporidian it is key investigate associations at smaller (local) scales. Thus, here, we explore effect variables (e.g., temperature, forest structure, anthropogenic disturbances) on...
In migratory insects performing multigenerational migration, such as the painted lady butterfly Vanessa cardui , successive generations face a wide variety of predator communities and may be subject to different predation risks. Here, we analyze pattern wing damage over 2000 butterflies investigate, for first time, risk adult ladies across latitudinal range ca 3500 km extending from northern Mediterranean through Maghreb sub‐Saharan West Africa. Large number showed substantial attributable...
The current distribution of Campbell’s monkeys Cercopithecus campbelli extends from southwestern Gambia to the western Ivory Coast. In Senegal, it has only been confirmed in part country. Here, we report for first time its presence southeastern Senegal. We obtained camera trap footage a monkey individual Dindefelo Community Nature Reserve located Kedougou region, 174 km away known range. footage, single appears alongside group at least nine green Chlorocebus sabaeus. discuss different...
Chimpanzees use spatiotemporal cognition for fruit foraging by remembering tree locations and fruiting seasons. However, the behind exploiting other foods has rarely been studied. Here, we investigate whether chimpanzees memory to exploit concealed, underground army ant nests. We analyse 679 chimpanzee visits four nests recorded during five years (2018–2022) using camera traps in a savanna habitat. explore if intentionally revisit nests, study how they detect ants, assess availability...
Abstract Mutualistic co-evolution can be mediated by vertical transmission of symbionts between host generations. Organisms exhibit adaptations that ensure optimal microbial inheritance, yet it is unknown if this extends to superorganismal social insects co-evolved gut microbiomes. Here, we document consistent preserves more than 80 bacterial genera across colony generations in a fungus-farming termite model system. Inheritance governed reproductives, analogous organismal gametes, found new...

Abstract Mutualistic co-evolution can be mediated by vertical transmission of symbionts between host generations. Organisms exhibit adaptations that ensure optimal microbial inheritance, yet the extent to which this applies social insects, such as termites have co-evolved with gut microbes, is poorly resolved. Here, we document consistent across colony generations fungus-farming termites. Inherited bacteria comprise 44% microbiome, over 80 genera, and strains are specific termite pedigrees....
